BACKGROUND OF THE INVENTION
[0006] Communication devices (e.g., mobile communication devices)
are continually increasing in popularity. Such communication
devices include, for example and without limitation, cellular
phones, paging devices, portable email devices, and personal
digital assistants. Mobile communication devices, for example,
provide the user with the capability to conduct communications
while moving through a variety of environments.
[0007] Mobile communication devices may operate in accordance with
multiple communication modes. For example a mobile communication
device may be adapted to operate in a cellular communication mode
and a wireless computer network communication mode. Such multimode
mobile communication devices may utilize respective radio
configurations for each communication mode. For example, various
communication modes may correspond to different respective radios
and/or different communication protocols.
[0008] As mobile communication devices increase in popularity,
communication networks providing communication links to such mobile
communication devices and various electronic devices providing
services to such mobile communication devices are also increasing
in popularity. The increase in communication network and device
availability provides an increasing number of communication options
to mobile communication devices. In addition, as mobile
communication devices move between environments, the array of
communication networks available to the mobile communication
devices also changes.
[0009] As the number of mobile communication devices and/or
communication networks or other devices increases, the complexity
of establishing and maintaining communication links between mobile
communication devices and communication networks or other devices
also increases. Such increased complexity, in turn, may result in
increased power consumption, increased cost, etc. Further
limitations and disadvantages of conventional and traditional
approaches will become apparent to one of skill in the art, through
comparison of such systems with the present invention as set forth
in the remainder of the present application with reference to the
drawings.
BRIEF SUMMARY OF THE INVENTION
[0010] Various aspects of the present invention comprise a system
and method providing location based wireless resource
identification in a communication system, substantially as shown in
and/or described in connection with at least one of the figures, as
set forth more completely in the claims. These and other
advantages, aspects and novel features of the present invention, as
well as details of illustrative aspects thereof, will be more fully

DETAILED DESCRIPTION OF THE INVENTION
[0016] FIG. 1 is a diagram illustrating a first exemplary method
for operating a communication system, in accordance with various
aspects of the present invention. The communication system may
comprise characteristics of any of a variety of communication
systems (e.g., multimode communication systems). For example and
without limitation, the communication system may comprise
characteristics of any of a variety of mobile communication devices
(e.g., cellular phones, paging devices, portable email devices,
etc.). Also for example, the communication system may comprise
characteristics of fixed communication systems or devices (e.g.,
network access points, base stations, satellites, wireless routers,
set top boxes, etc.). Further for example, the communication system
may comprise characteristics of a variety of electronic devices
with wireless communication capability (e.g., televisions, music
players, cameras, remote controls, personal digital assistants,
handheld computers, mobile gaming devices, etc.) Accordingly, the
scope of various aspects of the present invention should not be
limited by characteristics of particular communication systems or
devices.
[0017] The following discussion will, at times, refer to various
communication modes. For the following discussion, a communication
mode may generally be considered to coincide with communication
utilizing a particular communication protocol or standard. A
non-limiting list of exemplary communication protocols includes
various cellular communication protocols (e.g., GSM, GPRS, EDGE,
CDMA, WCDMA, TDMA, PDC, etc.), various wireless networking
protocols or standards, including WLAN, WMAN, WPAN and WWAN (e.g.,
IEEE 802.11, Bluetooth, IEEE 802.15, UWB, IEEE 802.16, IEEE 802.20,
Zigbee, any WiFi protocol, etc.), various television communication
standards, etc. Accordingly, the scope of various aspects of the
present invention should not be limited by characteristics of
particular communication modes or protocols, whether standard or
proprietary.
[0018] The exemplary method 100 begins executing at step 105. The
exemplary method 100 (and all methods discussed herein) may begin
executing for any of a large variety of reasons. For example and
without limitation, the exemplary method 100 may begin executing in
response to powering-up or resetting the communication system
implementing the method 100. Also for example, the exemplary method
100 may begin executing in response to a schedule (e.g.,
periodically, aperiodically, etc.). Further for example, the
exemplary method 100 may begin executing in response to a user
input directing the method 100 to begin executing. Additionally for
example, the exemplary method 100 may begin executing in response
to communication link conditions (e.g., a change in communication
link quality, whether better or worse). Accordingly, the scope of
various aspects of the present invention should not be limited by
characteristics of any particular initiating cause or
condition.
[0019] The exemplary method 100 may, at step 110, comprise
determining the location of the communication system (e.g., a
mobile multimode communication device) implementing the method 100.
Step 110 may comprise determining the location of the communication
system in any of a variety of manners, non-limiting examples of
which will be presented below.
[0020] For example, step 110 may comprise utilizing location or
location-related information received from various types of systems
generally associated with positioning information (e.g.,
terrestrial and/or satellite based positioning systems). As an
example, step 110 may comprise receiving and processing global
positioning system ("GPS") information to determine the location of
the communication system. Step 110 may, for example, utilize a GPS
receiver on-board the communication system to receive GPS
information.
[0021] Also for example, step 110 may comprise utilizing
ultrawideband ("UWB") positioning information to determine the
location of the communication system. As an example, step 110 may
comprise receiving UWB positioning information from a
position-tracking system. Various portions of such a
position-tracking system might be internal or external to the
communication system.
[0022] Further for example, step 110 may comprise receiving
location information from a communication network (or network
device) with which the communication system implementing the method
100 has established communication. As a non-limiting example, step
110 may comprise establishing a communication link with an access
point of a particular personal area network ("PAN") or local area
network ("LAN") that notifies the communication system of the
network or access point location.
[0023] Additionally for example, step 110 may comprise ascertaining
location of the communication system implementing the method 100
from one or more detected communication networks. For example, step
110 may comprise utilizing knowledge of communication network
location. As a non-limiting example, step 110 may comprise
ascertaining that the communication system is in the home when a
PAN associated with a home office is detected. As another
non-limiting example, step 110 may comprise ascertaining that the
communication system is at the office when the office LAN is
detected. As a further non-limiting example, step 110 may comprise
ascertaining that the communication system is at a particular
airport when the airport's LAN is detected, or that the
communication system is in a particular city when the city's
metropolitan area network ("MAN") is detected. Step 110 may
comprise ascertaining location of the communication system based on
any of a variety of detected networks (e.g., two-way communication
networks, one-way communication networks, television networks,
radio networks, etc.).
[0024] Further for example, step 110 may comprise ascertaining
location of the communication system implementing the method 100
from one or more detected devices. For example, step 110 may
comprise utilizing knowledge of device location. As a non-limiting
example, step 110 may comprise ascertaining that the communication
system is in the home when a home device is detected. Such devices
may, for example, include a computer, modem, printer, mouse,
keyboard, television, stereo, set top box, environmental control
system, alarm system, memory device, telephone, wireless relay,
video game box, or any home device with communication capability or
other detectable feature. As a further non-limiting example, step
110 may comprise ascertaining that the communication system is in
the office when an office device is detected. Such devices may, for
example, include an office computer, printer, telephone, modem,
router, fax machine, copier, keyboard, mouse, network access point,
wireless router/modem, database or any office device with
communication capability or other detectable feature.
[0025] Step 110 may, for example, comprise determining location of
a communication system implementing the method 100 by analyzing
communication link conditions. As a non-limiting example, step 110
may comprise determining that the communication system is in the
immediate vicinity of the office based on a relatively high-quality
communication link between the communication system and the office
LAN. Continuing the example, step 110 may alternatively comprise
determining that the communication system is at least one block
away from the office based on a relatively low-quality
communication link between the communication system and the office
LAN. As another example, step 110 may comprise determining that the
communication system is home but not within the home office based
on a relatively high-quality communication link with a home LAN and
a relatively low-quality communication link with a home office
PAN.
[0026] Step 110 may further, for example, comprise determining
location of a communication system implementing the method 100
based on user input. As a non-limiting example, a user may
explicitly indicate to the communication system that the
communication system is located in a particular city, building,
room, campus, etc.
[0027] In general, step 110 may comprise determining location of
the communication system. Accordingly, the scope of various aspects
of the present invention should not be limited by characteristics
of any particular manner of determining a communication system
location.
[0028] The exemplary method 100 may, at step 120, comprise
identifying one or more wireless resources based, at least in part,
on the determined location (e.g., as determined at step 110). Step
120 may comprise identifying one or more wireless resources in any
of a variety of manners, non-limiting examples of which will be
presented below.
[0029] A wireless resource may generally be considered a resource
(e.g., a wireless communication network, network access point or
other electronic device with wireless communication capability)
with which a communication system may communicate. For example, a
wireless resource may comprise a particular wireless communication
network or wireless network access point. Also for example, a
wireless resource may comprise a printer or memory device with
wireless communication capability. Further for example, a wireless
resource may comprise a wireless link to a wired or optical
communication network. Still further for example, a wireless
resource may comprise a wireless LAN, WAN or PAN access point. Yet
further for example, a wireless resource may comprise a
wireless-capable monitor, print, audio input or output device,
camera, keyboard, telephone, mouse, intercom system, environmental
control system, satellite transceiver, television, etc.
[0030] Identifying one or more wireless resources may generally
comprise determining any of a large variety of types of information
utilized to identify a wireless resource. For example, wireless
resource identification may comprise a single piece of information
related to a particular wireless resource or may comprise a
relatively large amount of information related to a relatively
complex array of wireless resources. For example and without
limitation, wireless resource identification information may
comprise resource name, type, address (universal and/or local),
characteristics, capabilities, communication protocols,
availability, status, location, access privileges, etc. The
following examples will provide non-limiting examples of
information that might be included in a wireless resource
identification.
[0031] Step 120 may, for example, comprise identifying a list of
wireless resources associated with the determined location. Such a
list of wireless resources may, for example, comprise a list of
wireless communication networks associated with the determined
location. Such a list of wireless resources may, for example,
comprise a list of electronic devices with wireless communication
capability that are associated with the determined location. Such a
list may also, for example, comprise any of a variety of types of
information associated with a wireless resource (e.g., resource
name, type, address (universal and/or local), characteristics,
capabilities, communication protocols, availability, status,
location, access privileges, etc.).
[0032] A list or other grouping of wireless resources associated
with a determined location may, for example, be formed from
information stored in a database. Such a database may, for example,
reside on-board the communication system (e.g., in a non-volatile
memory device) or may reside in another device communicatively
coupled to the communication system (e.g., through a communication
network, like a LAN or the Internet). Such a database may, for
example, comprise stored information correlating one or more
locations with one or more respective wireless resources. As will
be discussed in more detail later, such a database may be
maintained manually or automatically and/or managed off-line or in
real-time. A list of wireless resources may, for example, be
exclusive or non-exclusive. That is, such a list may, for example,
comprise a list of the only wireless resources that the
communication system is to utilize or may, for example, comprise a
list of primary resources that the communication system is to
utilize while allowing for the utilization of other wireless
resources that the communication system determines are
available.
[0033] Step 120 may, for example, comprise identifying a set of
wireless resources of a plurality of predetermined sets of wireless
resources, each of which might be associated with one or more
particular locations. In a non-limiting exemplary scenario, a first
set of wireless resources may be associated with a home location, a
second set of wireless resources may be associated with an office
location, a third set of wireless resources may be associated with
a commute (or portion thereof), and a fourth set of wireless
resources may be associated with a particular city. Note that in
various exemplary scenarios (e.g., located in an office), a
plurality of locations may be determined simultaneously (e.g.,
office, campus and city). Thus, in such exemplary scenarios, a
plurality of sets of wireless resources may be simultaneously
applicable.
[0034] Also for example, step 120 may comprise identifying unknown
wireless resources. For example, step 120 may comprise searching
for any wireless resources that are recognized and available. Such
identification may, for example, be performed in addition to, or in
lieu of, identifying known wireless resources. As an example, step
120 may comprise determining that no wireless resources are known
to be associated with the present location, and determining to
search for all recognized and available resources within range of
the location. Such searching may, for example, comprise performing
active searching (e.g., sending beacons and waiting for responses)
and/or passive searching (e.g., listening for beacons or other
signals sent by other devices). As will be mentioned later,
information of identified previously unknown resources may be
stored in a database for future reference.
[0035] Additionally for example, step 120 may comprise verifying
the existence and/or availability of known resources. For example,
step 120 may comprise first determining a list of wireless
resources that are known to be generally available at a particular
location, and then attempting to establish communication links with
the known devices to verify that the known devices are currently
available. As will be discussed later, information related to
resource verification may be utilized to update database
information for future reference.
[0036] In various exemplary scenarios, step 120 may also comprise
failing to identify any wireless resources associated with the
location. In such a scenario, as discussed above, step 120 may
comprise searching for unknown resources. Alternatively, in such a
scenario, step 120 may comprise not searching for other resources
(e.g., in an energy-saving mode or in accordance with a
user-defined behavioral profile).
[0037] Still further for example, step 120 may comprise interacting
with a user regarding wireless resources. For example, step 120 may
comprise receiving a user input identifying a set of wireless
resources to utilize until directed otherwise by the user. Also for
example, step 120 may comprise presenting a plurality of sets of
wireless resources to the user (e.g., on a display) for the user to
select from. Further for example, step 120 may comprise presenting
any of a variety of types of information regarding wireless
resources to a user and acquiring user input regarding the
presented information.
[0038] In general, step 120 may comprise identifying one or more
wireless resources based, at least in part, on the determined
location. Accordingly, the scope of various aspects of the present
invention should not be limited by characteristics of one or more
particular manners of identifying wireless resources.
[0039] The exemplary method 100 may, at step 130, comprise
identifying respective manner(s) of communicating with the
identified wireless resources(s) (e.g., as identified at step 120).
Step 130 may comprise identifying the respective manner(s) of
communicating with the identified wireless resource(s) in any of a
variety of manners, non-limiting examples of which will be provided
below.
[0040] For example, step 130 may comprise identifying at least one
radio of a plurality of radios of the communication system (e.g., a
mobile multimode communication device) to utilize to communicate
with identified wireless resources (e.g., as identified at step
120). As a non-limiting example, a multimode communication device
may comprise a first radio adapted to communicate utilizing a first
communication protocol or standard (e.g., IEEE 802.11), a second
radio adapted to communicate utilizing a second communication
protocol or standard (e.g., Bluetooth) and a third radio adapted to
communicate utilizing a third communication protocol or standard
(e.g., IEEE 802.15). Continuing the non-limiting example, step 110
may comprise determining that the communication system implementing
the method 100 is located in an office. Step 120 may then comprise
identifying a first wireless resource (e.g., a video monitor) that
communicates utilizing the second communication protocol and a
second wireless resource (e.g., a LAN access point) that
communicates utilizing the first communication protocol. Step 130
may then, for example, comprise identifying the second radio for
communicating with the first wireless resource and identifying the
first radio for communicating with the second wireless
resource.
[0041] Also for example, step 130 may comprise identifying at least
one radio configuration profile with which to configure a
programmable radio of the communication system (e.g., a multimode
communication device). As a non-limiting example, a multimode
communication device may comprise a programmable radio that is
configurable to communicate in accordance with a plurality of
communication protocols (or standards). In a non-limiting exemplary
scenario, a first configuration profile may correspond to
communicating utilizing GSM, a second configuration profile may
correspond to communicating utilizing EDGE, a third configuration
profile may correspond to communicating utilizing IEEE 802.20, and
a fourth configuration profile may correspond to communicating
utilizing WCDMA. Continuing the non-limiting exemplary scenario,
step 110 may comprise determining that the communication system
implementing the method 100 is located in the home living room.
Step 120 may then comprise identifying a first wireless resource
(e.g., a set top box) and a second wireless resource (e.g., a GSM
cellular network) associated with the home living room location.
Step 130 may then comprise identifying the third configuration
profile for communicating with the set top box utilizing IEEE
802.20 and identifying the first configuration profile for placing
a telephone call utilizing the GSM cellular network.
[0042] For a non-limiting exemplary discussion of programmable
radio configurations generally, refer to U.S. patent application
Ser. No. 11/217,645, entitled "MULTIMEDIA COMMUNICATION DEVICE WITH
CONFIGURATION UPDATE CAPABILITY," filed Sep. 1, 2005, and U.S.
patent application Ser. No. ___/___,___, entitled "PROGRAMMABLE
WIRELESS ACCESS POINT SUPPORTING CONFIGURATION PROFILE UPDATING,"
filed ______, with attorney docket number 16864US01, which are
hereby incorporated herein by reference in their entirety.
[0043] Further for example, step 130 may comprise identifying at
least one communication protocol (or standard) of a plurality of
communication protocols (or standards) to utilize for
communications. In a non-limiting exemplary scenario, the
communication system implementing the exemplary method 100 may be
adapted to communicate utilizing a first communication protocol
(e.g., IEEE 802.11), a second communication protocol (e.g.,
Bluetooth), a third communication protocol (e.g., IEEE 802.16) and
a fourth communication protocol (e.g., WCDMA). Continuing the
exemplary scenario, step 110 may comprise determining that the
communication system implementing the system is located in a
particular conference room in a particular building. Step 120 may
then, for example, comprise identifying a first wireless resource
(e.g., a Bluetooth-based wireless LAN access point), a second
wireless resource (e.g., an IEEE 802.16-based video projector) and
a third wireless resource (e.g., a Bluetooth-based audio output
device). Continuing the exemplary scenario, step 130 may then
comprise identifying the second communication protocol for
communicating with the wireless LAN, the third communication
protocol for communicating with the video projector and the second
communication protocol for communicating with the audio output
device.
[0044] Note that communication protocol (or standard)
identification may also comprise various implementation details
associated with a communication protocol. Such protocol
implementation details may, for example and without limitation,
comprise power information, frequency information, secure
communication information, etc. Note also that such information may
vary based on location. For example, different geographical regions
may have different respective maximum power limits associated with
the IEEE 802.11 standard and/or may require operation in different
respective frequency bands. Accordingly, implementing a first
protocol at a first location may be different from implementing the
first protocol at a second location.
[0045] In general, step 130 may comprise identifying respective
manner(s) of communicating with the identified wireless
resources(s). Accordingly, the scope of various aspects of the
present invention should not be limited by characteristics of any
particular manner of identifying a manner of communicating.
[0046] The exemplary method 100 may, at step 140, comprise
communicating with the identified wireless resources (e.g., as
identified at step 120) in particular respective manners (e.g., as
identified at step 130). Step 140 may comprise communicating with
the identified wireless resources in any of a variety of
manners.
[0047] The exemplary method 100 may, at step 195, comprise
performing continued processing. Such continued processing may
comprise performing any of a variety of continued processing
activities. For example and without limitation, as will be
discussed later, step 195 may comprise maintaining wireless
resource database information. Also for example, step 195 may
comprise returning execution flow of the exemplary method 100 back
to redetermine location at step 110 and continue operation. Further
for example, step 195 may comprise receiving operational
information from a user. Still further for example, step 195 may
comprise periodically performing searches for unknown wireless
resources and/or verification of the existence and/or availability
of known wireless resources.
[0048] The exemplary method 100 was presented to provide
non-limiting exemplary illustrations of various aspects of the
present invention. Accordingly, the scope of various aspects of the
present invention should not be limited by characteristics of the
exemplary method 100.
[0049] FIG. 2 is a diagram illustrating a method 200 for operating
a communication system (e.g., a multimode communication device), in
accordance with various aspects of the present invention. The
exemplary method 200 may, for example and without limitation, share
any or all characteristics with the exemplary method 100
illustrated in FIG. 1 and discussed previously.
[0050] The exemplary method 200 may, at step 210, comprise
receiving information regarding the location of the communication
system (e.g., from a source external to the communication
system/device implementing the method 200). Step 210 may, for
example and without limitation, share any or all characteristics
with step 110 of the exemplary method 100 discussed previously. For
example, step 210 may comprise receiving such information from a
dedicated navigational or positional system (e.g., GPS), from a
communication network or device to which the communication system
is communicatively coupled, from a user, etc.
[0051] The exemplary method 200 may, at step 212, comprise
determining whether the communication system implementing the
method 200 is located at (or near) a known location (e.g., a
location at which the communication system has a communication
history with known wireless resources). Step 212 may, for example
and without limitation, comprise searching a database or other
memory storage for information regarding the location. In a
non-limiting exemplary scenario, step 212 may comprise determining
that there is no database information corresponding to the
location, and thus, determining that the location is unknown. In
another non-limiting exemplary scenario, step 212 may comprise
determining that there is database information corresponding to the
location and that the information indicates that there are no known
wireless resources associated with the location, and thus,
determining that the location is to be treated as an unknown
location. In a further non-limiting exemplary scenario, step 212
may comprise soliciting and receiving user input regarding a
present location to determine whether the location is unknown or to
be treated as unknown. In general, step 212 may comprise
determining whether the location is unknown (or to be treated as
such) in any of a variety of manners.
[0052] If step 212 comprises determining that the location is a
known location, then step 212 may comprise directing execution flow
of the exemplary method 200 to steps 220 and 230. Steps 220 and 230
may, for example, comprise identifying one or more wireless
resources based, at least in part, on the determined location and
identifying respective manner(s) for communicating with the
identified wireless resources(s). Steps 220 and 230 may, for
example and without limitation, share any or all characteristics
with steps 120 and 130 of the exemplary method 100 illustrated in
FIG. 1 and discussed previously.
[0053] If step 212 comprises determining that the location is not a
known location, then step 212 may comprise directing execution flow
of the exemplary method 200 to step 214. Step 214 may then, in
turn, comprise determining whether to search for unknown wireless
resources. Step 214 may comprise making such determination in any
of a variety of manners. For example and without limitation, step
214 may comprise soliciting input from a user (e.g., in real time)
regarding whether to search for unknown wireless resources. Also
for example, step 214 may comprise making such determination by
analyzing a pre-defined profile (e.g., defined in non-real time
prior to the real-time need for such information) indicating
whether to search for unknown wireless resources. Such a profile
may, for example, indicate to the communication system implementing
the method 200 the circumstances under which the communication
system is to search for unknown wireless resources. As a further
example, step 214 may comprise determining whether to search for
unknown wireless resources based on present power supply levels of
the communication system. As yet another example, step 214 may
comprise always or never searching for unknown wireless
resources.
[0054] If step 214 determines that no search for unknown wireless
resources is to be conducted, then step 214 may comprise directing
execution flow of the exemplary method 200 to step 216, which
delays further execution of the method 200. Step 216 may, for
example and without limitation, comprise implementing a predefined
time delay (e.g., periodic, random or according to a predefined
profile). Step 216 may also, for example, comprise waiting for any
of a variety of events to occur before continuing execution of the
method 200. After implementing the delay, step 216 may direct
execution flow of the exemplary method 200 to step 210 for
receiving updated information regarding the location of the
communication system.
[0055] If step 214 determines that a search for unknown wireless
resources is to be conducted, then step 214 may comprise directing
execution flow of the exemplary method 200 to step 218, which
comprises searching for unknown wireless resources. Various
non-limiting exemplary manners of searching for unknown wireless
resources were discussed previously. For example and without
limitation, step 218 may comprise actively searching for unknown
wireless resources. Such active searching may, for example,
comprise transmitting beacon signals and analyzing return signals.
Such active searching may also, for example, comprise communicating
with a database (e.g, through the Internet and/or cellular
telephony infrastructure) to determine whether there are any
records of particular wireless resources associated with the
location. Step 218 may alternatively, for example, comprise
performing passive searching for wireless resources. Such passive
searching may, for example, comprise passively listening for beacon
signals or other signals transmitted by wireless resources. Such
passive searching may also, for example, comprise passively
listening for wireless resource identification information
transmitted by other devices.
[0056] In various non-limiting exemplary scenarios, as part of
searching for unknown wireless resources, step 218 may also
comprise identifying respective manner(s) for communicating with
the identified wireless resources(s). Examples of such manners of
communication were presented previously with regard to step 130 of
the exemplary method 100 discussed previously. For example and
without limitation, step 218 may comprise analyzing received
signals (e.g., beacon signals or responses to beacon signals) to
determine a manner of communicating with identified wireless
resources. Also for example, step 218 may comprise analyzing
database information associated with identified wireless resources
to determine such manners of communication. Further for example,
step 218 may comprise communicating with a wireless resource using
a first manner of communication to determine other manners of
communication with which the wireless resource may communicate.
[0057] The exemplary method 200 may, at step 240, comprise
communicating with the identified wireless resources (e.g., as
identified at step 220 and/or step 218) in particular respective
manners (e.g., as identified at step 230 and/or step 218). Step 240
may comprise communicating with the identified wireless resources
in any of a variety of manners.
[0058] The exemplary method 200 may, at step 295, comprise
performing continued processing. Such continued processing may
comprise performing any of a variety of continued processing
activities. For example and without limitation, as will be
discussed later, step 295 may comprise maintaining wireless
resource database information. Also for example, step 295 may
comprise returning execution flow of the exemplary method 200 back
to re-determine location at step 210 and continue operation.
Further for example, step 295 may comprise receiving operational
information from a user. Still further for example, step 295 may
comprise periodically performing searches for unknown wireless
resources and/or verification of the existence and/or availability
of known wireless resources. Yet further for example, step 295 may
comprise returning execution flow of the exemplary method 200 to
step 214 to search for unknown wireless resources (e.g., even in a
scenario involving a known location).
[0059] The exemplary method 200 was presented to provide
non-limiting exemplary illustrations of various aspects of the
present invention. Accordingly, the scope of various aspects of the
present invention should not be limited by characteristics of the
exemplary method 200.
[0060] FIG. 3 is a diagram illustrating a third exemplary method
300 for operating a communication system (e.g., a multimode
communication device), in accordance with various aspects of the
present invention. The exemplary method 300 may, for example and
without limitation, share any or all characteristics with the
exemplary methods 100, 200 illustrated in FIGS. 1-2 and discussed
previously.
[0061] The exemplary method 300 may, at step 310, comprise
determining location of a communication system implementing the
method 300. Step 310 may, for example and without limitation, share
any or all characteristics with steps 110 and 210 of the exemplary
methods 100, 200 illustrated in FIGS. 1-2 and discussed
previously.
[0062] As a non-limiting exemplary sub-step of step 310, the
exemplary method 300 may, at step 311, comprise detecting a known
communication network and/or electronic device. Such a
communication network may, for example, be a wireless communication
network, and such a device may, for example, comprise wireless
communication capability. Such detection may, for example, comprise
processing a received signal (e.g., a beacon or other signal)
transmitted from a network or electronic device. Such detection may
also, for example, comprise processing a message received from a
network or electronic device in response to a transmitted signal
(e.g., a beacon or other signal). Such detection may further, for
example, comprise establishing two-way way communication with a
network or electronic device.
[0063] As another non-limiting exemplary sub-step of step 310, the
exemplary method 300 may, at step 312, comprise ascertaining
location of the communication system from one or more detected
networks and/or devices. For example, step 312 may comprise
utilizing knowledge of network and/or device location. As a
non-limiting example, step 312 may comprise ascertaining that a
communication system is in the home when a PAN associated with a
home office and/or a printer associated with a home office is
detected (e.g., detected at step 311). As another non-limiting
limiting example, step 312 may comprise ascertaining that the
communication system is at the office when the office LAN is
detected and/or a PC associated with the office is detected. As a
further non-limiting example, step 312 may comprise ascertaining
that the communication system is at a particular airport when the
airport's LAN is detected, or that the communication system is in a
particular city when the city's MAN or television station is
detected. Step 312 may comprise ascertaining location of the
communication system based on any of a variety of detected networks
and/or devices (e.g., two-way communication network, one-way
communication network, television network, radio network, office
computer, printer, telephone, modem, router, fax machine, copier,
keyboard, mouse, network access point, wireless router/modem,
database or any device with communication capability or other
detectable feature etc.).
[0064] The exemplary method 300 may, at step 320, comprise
searching (e.g., querying) a wireless resource database to identify
one or more wireless resources associated with the location (e.g.,
determined at step 310). Such a database may, for example, comprise
stored information corresponding to wireless resources associated
with particular locations. Such a database may, for example, reside
on-board the communication system (e.g., in a non-volatile memory
device) or may reside in another device communicatively coupled to
the communication system (e.g., through a communication network,
like a LAN or the Internet). Such a database may, for example,
comprise stored information correlating one or more locations with
one or more respective wireless resources.
[0065] Such a database may, for example, be maintained manually or
automatically. For example, a user of the communication system may
maintain information in the database and/or the communication
system may itself maintain information in the database without
interaction with a user. Such a database may, for example, be
maintained specifically for the communication system or may be
maintained for a plurality of communication systems that may access
the database.
[0066] In a non-limiting exemplary scenario, the database may
comprise information of wireless resources associated with a home,
home office, family room, etc. Also for example, the database may
comprise information of wireless resources associated with an
office, office suite or group of offices. Further for example, the
database may comprise information of wireless resources associated
with a campus or metropolitan area.
[0067] The exemplary method 300 may, at step 330, comprise
identifying respective manner(s) of communicating with the
identified wireless resources(s) (e.g., as identified at step 320).
Step 330 may, for example and without limitation, share any or all
characteristics with steps 130 and 230 of the exemplary methods
100, 200 illustrated in FIGS. 1-2 and discussed previously. As a
non-limiting example, step 330 may comprise identifying manner(s)
of communicating with the identified wireless resource(s) by
communicating with a database that includes stored information
identifying manner(s) of communicating associated with particular
wireless resources. Such a database may, for example, be the same
database utilized at step 320 to identify the wireless
resources.
[0068] The exemplary method 300 may, at steps 314 and 318,
determine whether to search for unknown wireless resources and
perform such searching if deemed necessary. Steps 314 and 318 may,
for example and without limitation, share any or all
characteristics with steps 214 and 218 of the exemplary method 200
discussed previously.
[0069] The exemplary method 300 may, at step 319, comprise
maintaining (e.g., updating) a database of wireless resource
information (e.g., as utilized at step 320 and/or step 330)
associated with particular locations. Such updating may, for
example, comprise updating the database regarding wireless
resources previously identified as "known" resources, where such
devices are no longer available. Such updating may also, for
example, comprise updating the database regarding previously
unknown wireless resources identified at step 318. As mentioned
previously, such a database may be on-board the communication
system or may be off-board.
[0070] The exemplary method 300 may, at step 340, comprise
communicating with identified wireless resources as necessary. Step
340 may, for example and without limitation, share any or all
characteristics with steps 140 and 240 of the exemplary methods
100, 200 illustrated in FIGS. 1-2 and discussed previously.
[0071] The exemplary method 300 was presented to provide
non-limiting exemplary illustrations of various aspects of the
present invention. Accordingly, the scope of various aspects of the
present invention should not be limited by characteristics of the
exemplary method 300.
[0072] FIG. 4 is a diagram illustrating a portion of a first
exemplary communication system 400, in accordance with various
aspects of the present invention. The exemplary communication
system 400 may, for example and without limitation, share any or
all functional characteristics with the exemplary methods 100, 200,
300 illustrated in FIGS. 1-3 and discussed previously.
[0073] As explained previously with regard to FIG. 1, the exemplary
communication system 400 may comprise characteristics of any of a
variety of types of communication systems (e.g., fixed or mobile
multimode communication devices).
[0074] The exemplary communication system 400 may comprise one or
more wireless interface modules 410. The wireless interface
module(s) 410 may comprise characteristics of any of a variety of
wireless interface hardware and/or software. For example, the
wireless interface module(s) 410 may comprise a plurality of radios
dedicated to communicating in respective modes associated with
respective communication protocols and/or standards. Also for
example, the wireless interface module(s) 410 may comprise one or
more programmable radios that are programmable to communicate in
any of a plurality of communication modes, depending on the
programming.
[0075] For a non-limiting exemplary discussion of programmable
radio configurations generally, refer to U.S. patent application
Ser. No. 11/217,645, entitled "MULTIMEDIA COMMUNICATION DEVICE WITH
CONFIGURATION UPDATE CAPABILITY," filed Sep. 1, 2005, and U.S.
patent application Ser. No. ___/___,___, entitled "PROGRAMMABLE
WIRELESS ACCESS POINT SUPPORTING CONFIGURATION PROFILE UPDATING,"
filed ______, with attorney docket number 16864US01, which are
hereby incorporated herein by reference in their entirety.
[0076] The exemplary communication system 400 may further comprise
one or more user interface modules 450. The user interface
module(s) 450 may generally be adapted to provide a communication
link between the communication system 400 and a user of the
communication system 400. The user interface module(s) 450 may
comprise characteristics of any of a variety of user interface
module(s). Accordingly, the scope of various aspects of the present
invention should not be limited by characteristics of any
particular type of user interface module.
[0077] The exemplary communication system 400 may comprise a
location determination module 420 adapted to determine a location
of the communication system 400. The location determination module
420 may, for example and without limitation, share any or all
finctional characteristics with steps 110, 210 and 310 of the
exemplary methods 100, 200, 300 illustrated in FIGS. 1-3 and
discussed previously.
[0078] For example and without limitation, the location
determination module 420 may be adapted to acquire (e.g., utilizing
the wireless interface module(s) 410) and utilize location-related
information received from various types of systems generally
associated with positioning information (e.g., terrestrial and/or
satellite-based positioning systems). As an example, the location
determination module 420 may be adapted to receive and process GPS
and/or UWB information to determine the location of the
communication system 400. The location determination module 420 (or
other module of the communication system 400, for example, the
wireless interface modules 410) may, for example, comprise an
on-board GPS and/or other location information receiver. Note that
portions of a position tracking system may be included in the
communication system 400.
[0079] Further for example, the location determination module 420
may be adapted to receive location information from a communication
network (or network device) with which the communication system 400
has established communication (e.g., utilizing the wireless
interface module(s) 410). As a non-limiting example, the location
determination module 420 may be adapted to establish a
communication link with an access point of a particular personal
area network ("PAN") or local area network ("LAN") that then
notifies the communication system 400 of the network or access
point location.
[0080] Additionally for example, the location determination module
420 may be adapted to ascertain location of the communication
system 400 from one or more detected communication networks. For
example, the location determination module 420 may be adapted to
utilize knowledge of communication network location. As a
non-limiting example, the location determination module 420 may be
adapted to ascertain that the communication system 400 is in the
home when a PAN associated with a home office is detected (e.g.,
utilizing the wireless interface module(s) 410). As another
non-limiting example, the location determination module 420 may be
adapted to ascertain that the communication system 400 is at the
office when the office LAN is detected. As a further non-limiting
example, the location determination module 420 may be adapted to
ascertain that the communication system 400 is at a particular
airport when the airport's LAN is detected, or that the
communication system 400 is in a particular city when the city's
MAN is detected. The location determination module 420 may be
adapted to ascertain location of the communication system 400 based
on any of a variety of detected networks (e.g., two-way
communication networks, one-way communication networks, television
networks, radio networks, etc.).
[0081] Further for example, the location determination module 420
may be adapted to ascertain location of the communication system
400 from one or more detected electronic devices. For example, the
location determination module 420 may be adapted to utilize
knowledge of device location. As a non-limiting example, the
location determination module 420 may be adapted to ascertain that
the communication system 400 is in the home when a home device is
detected (e.g., utilizing the wireless interface module(s) 410).
Various examples of such devices were provided previously. As a
further non-limiting example, the location determination module 420
may be adapted to ascertain that the communication system 400 is in
the office when an office device is detected. Various examples of
such devices were provided previously.
[0082] The location determination module 420 may, for example, be
adapted to determine location of the communication system 400 by
analyzing communication link conditions (e.g., utilizing the
wireless interface module(s) 410). As a non-limiting example, the
location determination module 420 may be adapted to determine that
the communication system 400 is in the immediate vicinity of the
office based on a relatively high-quality communication link
between the communication system 400 and the office LAN. Continuing
the example, the location determination module 420 may
alternatively be adapted to determine that the communication system
400 is at least one block away from the office based on a
relatively low-quality communication link between the communication
system 400 and the office LAN. As another example, the location
determination module 420 may be adapted to determine that the
communication system 400 is home but not within the home office
based on a relatively high-quality communication link with a home
LAN and a relatively low-quality communication link with a home
office PAN.
[0083] The location determination module 420 may further, for
example, be adapted to determine location of the communication
system 400 based on user input. As a non-limiting example, a user
may explicitly indicate to the communication system 400 (e.g.,
through the user interface module(s) 450) that the communication
system 400 is located in a particular city, building, room, campus,
etc.
[0084] In general, the location determination module 420 may be
adapted to determine location of the communication system 400.
Accordingly, the scope of various aspects of the present invention
should not be limited by characteristics of any particular manner
of, or mechanism for, determining a communication system
location.
[0085] The exemplary communication system 400 may comprise a
wireless resource identification module 430 adapted to identify one
or more wireless resources based, at least in part, on the
determined location (e.g., as determined by the location
determination module 420). The wireless resource identification
module 430 may, for example and without limitation, share any or
all functional characteristics with steps 120, 220 and 320 and with
steps 212-218 and 314-318 of the exemplary methods 100, 200, 300
illustrated in FIGS. 1-3 and discussed previously.
[0086] The wireless resource identification module 430 may be
adapted to identify one or more wireless resources in any of a
variety of manners, non-limiting examples of which will be
presented below. Various aspects of wireless resources and the
identification of wireless resources were presented previously.
[0087] The wireless resource identification module 430 may, for
example, be adapted to identify a list of wireless resources
associated with the determined location. Such a list of wireless
resources may, for example, comprise a list of wireless
communication networks associated with the determined location.
Such a list of wireless resources may, for example, comprise a list
of electronic devices with wireless communication capability that
are associated with the determined location. Such a list may also,
for example, comprise any of a variety of types of information
associated with a wireless resource (e.g., resource name, type,
address (universal and/or local), characteristics, capabilities,
communication protocols, availability, status, location, access
privileges, etc.).
[0088] A list or other grouping of wireless resources associated
with a determined location may, for example, be formed from
information stored in a database. Such a database may, for example
reside on-board the communication system 400 (e.g., in a
non-volatile memory device) or may reside in another device
communicatively coupled to the communication system 400 (e.g.,
through a communication network, like a LAN or the Internet). Such
a database may, for example, comprise stored information
correlating one or more locations with one or more respective
wireless resources. As will be discussed in more detail later, such
a database may be maintained manually or automatically and/or
managed off-line or in real-time. A list of wireless resources may,
for example, be exclusive or non-exclusive. That is, such a list
may, for example, comprise a list of the only wireless resources
that the communication system 400 is to utilize or may, for
example, comprise a list of primary resources that the
communication system 400 is to utilize while allowing for the
utilization of other wireless resources that the communication
system 400 determines are available.
[0089] The wireless resource identification module 430 may, for
example, be adapted to identify a set of wireless resources of a
plurality of predetermined sets of wireless resources, each of
which might be associated with one or more particular locations. In
a non-limiting exemplary scenario, a first set of wireless
resources may be associated with a home location, a second set of
wireless resources may be associated with an office location, a
third set of wireless resources may be associated with a commute
(or portion thereof), and a fourth set of wireless resources may be
associated with a particular city. Note that in various exemplary
scenarios (e.g., located in an office), a plurality of locations
may be determined simultaneously (e.g., office, campus and city).
Thus, in such exemplary scenarios, a plurality of sets of wireless
resources may be simultaneously applicable.
[0090] Also for example, the wireless resource identification
module 430 may be adapted to identify unknown wireless resources.
For example, the wireless resource identification module 430 may be
adapted to search for any wireless resources that are recognized
and available. In various exemplary scenarios, the wireless
resource identification module 430 may be adapted to utilize the
wireless interface modules 410, or portions thereof, to perform
such searching. Such identification may, for example, be performed
in addition to, or in lieu of, identifying known wireless
resources. As an example, the wireless resource identification
module 430 may be adapted to determine that no wireless resources
are known to be associated with the present location, and determine
to search for all recognized and available resources within range
of the location. Such searching may, for example, comprise
performing active searching (e.g., sending beacons and waiting for
responses) and/or passive searching (e.g., listening for beacons or
other signals sent by other devices). In various exemplary
scenarios, information of identified previously unknown resources
may be stored in a database for future reference.
[0091] Additionally for example, the wireless resource
identification module 430 may be adapted to verify the existence
and/or availability of known resources. In various exemplary
scenarios, the wireless resource identification module 430 may be
adapted to utilize the wireless interface module 410, or portions
thereof, to perform such searching. For example, the wireless
resource identification module 430 may be adapted to first
determine a list of wireless resources that are known to be
generally available at a particular location, and then attempt to
establish communication links with the known devices to verify that
the known devices are currently available. As will be discussed
later, information related to resource verification may be utilized
to update database information for future reference.
[0092] In various exemplary scenarios, the wireless resource
identification module 430 may also fail to identify any wireless
resources associated with the location. In such a scenario, as
discussed above, the wireless resource identification module 430
may be adapted to search for unknown resources. Alternatively, in
such a scenario, the wireless resource identification module 430
may be adapted to not search for other resources (e.g., in an
energy-saving mode or in accordance with a user-defined behavioral
profile).
[0093] Still further for example, the wireless resource
identification module 430 may be adapted to interact with a user
regarding wireless resources. For example, the wireless resource
identification module 430 may be adapted to receive a user input
(e.g., utilizing the user interface modules 450) identifying a set
of wireless resources to utilize until directed otherwise by the
user. Also for example, the wireless resource identification module
430 may be adapted to present a plurality of sets of wireless
resources to the user (e.g., on a display coupled to the user
interface modules 450) for the user to select from. Further for
example, the wireless resource identification module 430 may be
adapted to utilize the user interface modules 450 to present any of
a variety of types of information regarding wireless resources to a
user and acquiring user input regarding the presented
information.
[0094] As mentioned previously, the wireless resource
identification module 430 may be adapted to determine whether the
communication system 400 is located at (or near) a known location
(e.g., a location at which the communication system 400 has a
communication history with known wireless resources). In a
non-limiting exemplary scenario, the wireless resource
identification module 430 may be adapted to search (or query) a
database or other memory storage for information regarding the
location. In one example, the wireless resource identification
module 430 may, for example, be adapted to determine that there is
no database information corresponding to the location, and thus,
determine that the location is unknown. In another example, the
wireless resource identification module 430 may be adapted to
determine that there is database information corresponding to the
location and that the information indicates that there are no known
wireless resources associated with the location, and thus,
determine that the location is to be treated as an unknown
location. In a further non-limiting exemplary scenario, the
wireless resource identification module 430 may be adapted to
solicit and receive user input (e.g., utilizing the user interface
modules 450) regarding a present location to determine whether the
location is unknown or to be treated as unknown. In general, the
wireless resource identification module 430 may be adapted to
determine whether the location is unknown (or to be treated as
such) in any of a variety of manners.
[0095] If, for example, the wireless resource identification module
430 determines that the location is a known location, then the
wireless resource identification module 430 may be adapted to
identify one or more wireless resources based, at least in part, on
the determined location and identify respective manner(s) for
communicating with the identified wireless resources(s).
[0096] If, for example, the wireless resource identification module
430 determines that the location is not a known location, then the
wireless resource identification module 430 may be adapted to
determine whether to search for unknown wireless resources. The
wireless resource identification module 430 may be adapted to make
such a determination in any of a variety of manners. For example
and without limitation, the wireless resource identification module
430 may be adapted to solicit input from a user (e.g., in real time
utilizing the user interface modules 450) regarding whether to
search for unknown wireless resources. Also for example, the
wireless resource identification module 430 may be adapted to make
such a determination by analyzing a pre-defined profile (e.g.,
defined in non-real time prior to the real-time need for such
information) indicating whether to search for unknown wireless
resources. Such a profile may, for example, indicate to the
communication system 400 the circumstances under which the
communication system 400 is to search for unknown wireless
resources. As a further example, the wireless resource
identification module 430 may be adapted to determine whether to
search for unknown wireless resources based on present power supply
levels of the communication system 400. As yet another example, the
wireless resource identification module 430 may be adapted to
always or never search for unknown wireless resources.
[0097] If the wireless resource identification module 430
determines that no search for unknown wireless resources is to be
conducted, then the wireless resource identification module 430
may, in various scenarios, implement a delay of some sort (e.g., to
conserve finite power resources). For example and without
limitation, the wireless resource identification module 430 may be
adapted to implement a predefined time delay (e.g., periodic,
random or according to a predefined schedule or profile). The
wireless resource identification module 430 may also, for example,
be adapted to wait for any of a variety of events to occur before
continuing operation. After implementing the delay, the wireless
resource identification module 430 may be adapted to receiving
updated information regarding the location of the communication
system 400.
[0098] If the wireless resource identification module 430
determines that a search for unknown wireless resources is to be
conducted, the wireless resource identification module 430 may be
adapted to search for unknown wireless resources. Various
non-limiting exemplary manners of searching for unknown wireless
resources were discussed previously. For example and without
limitation, the wireless resource identification module 430 may be
adapted to actively search for unknown wireless resources. Such
active searching may, for example, comprise transmitting beacon
signals and analyzing return signals (e.g., utilizing the wireless
interface modules 410). Such active searching may also, for
example, comprise communicating with a database (e.g., locally,
through the Internet and/or through the cellular telephony
infrastructure) to determine whether there are any records of
particular wireless resources associated with the location. The
wireless resource identification module 430 may alternatively, for
example, be adapted to perform passive searching for wireless
resources (e.g., utilizing the wireless interface modules 410).
Such passive searching may, for example, comprise passively
listening for beacon or other signals transmitted by wireless
resources. Such passive searching may also, for example, comprise
passively listening for wireless resource identification
information transmitted by other devices.
[0099] As part of searching for unknown wireless resources, the
wireless resource identification module 430 may also be adapted to
identify respective manner(s) of communicating with the identified
wireless resources(s). Examples of such manners of communication
were presented previously. For example and without limitation, the
wireless resource identification module 430 may be adapted to
analyze received signals (e.g., beacon signals or responses to
beacon signals) to determine a manner of communicating with
identified wireless resources. Also for example, the wireless
resource identification module 430 may be adapted to analyze
database information associated with identified wireless resources
to determine such manners of communication. Further for example,
the wireless resource identification module 430 may be adapted to
communicate with a wireless resource using a first manner of
communication (e.g., utilizing the wireless interface modules 410)
to determine other manners of communication with which the wireless
resource may communicate.
[0100] In general, the wireless resource identification module 430
is adapted to identify one or more wireless resources based, at
least in part, on the determined location. Accordingly, the scope
of various aspects of the present invention should not be limited
by characteristics of one or more particular manners of, or
mechanisms for, identifying wireless resources.
[0101] The exemplary communication system 400 may also comprise a
communication manager module 440 adapted to identify respective
manner(s) of communicating with the identified wireless resource(s)
(e.g., as identified by the wireless resource identification module
430). The communication manager module 440 may, for example and
without limitation, share any or all functional characteristics
with steps 130, 230 and 330 and with steps 140, 240 and 340 of the
exemplary methods 100, 200, 300 illustrated in FIGS. 1-3 and
discussed previously.
[0102] The communication manager module 440 may, for example, be
adapted to identify respective manner(s) of communicating with the
identified wireless resources(s) (e.g., as identified by the
wireless resource identification module 430). The communication
manager module 440 may be adapted to identify the respective
manner(s) of communicating with the identified wireless resource(s)
in any of a variety of manners, non-limiting examples of which will
be presented below.
[0103] For example, the communication manager module 440 may be
adapted to identify at least one radio of a plurality of radios of
the communication system 400 to utilize to communicate with
identified wireless resources (e.g., as identified by the wireless
resource identification module 430). As a non-limiting example, the
communication system 400 may (e.g., as wireless interface modules
410) comprise a first radio adapted to communicate utilizing a
first communication protocol or standard (e.g., IEEE 802.11), a
second radio adapted to communicate utilizing a second
communication protocol or standard (e.g., Bluetooth) and a third
radio adapted to communicate utilizing a third communication
protocol or standard (e.g., IEEE 802.15). Continuing the
non-limiting example, the location determination module 420 may
determine that the communication system 400 is located in an
office. The wireless resource identification module 430 may then
identify a first wireless resource (e.g., a video monitor) that
communicates utilizing the second communication protocol and a
second wireless resource (e.g., a LAN access point) that
communicates utilizing the first communication protocol. The
communication manager module 440 may then, for example, identify
the second radio for communicating with the first wireless resource
and identify the first radio for communicating with the second
wireless resource.
[0104] Also for example, the communication manager module 440 may
be adapted to identify at least one radio configuration profile
with which to configure a programmable radio (e.g., of the wireless
interface modules 410) of the communication system 400. As a
non-limiting example, a multimode communication device may comprise
a programmable radio that is configurable to communicate in
accordance with a plurality of communication protocols (or
standards). In a non-limiting exemplary scenario, a first
configuration profile may correspond to communicating utilizing
GSM, a second configuration profile may correspond to communicating
utilizing EDGE, a third configuration profile may correspond to
communicating utilizing IEEE 802.20, and a fourth configuration
profile may correspond to communicating utilizing WCDMA. Continuing
the non-limiting exemplary scenario, the location determination
module 420 may determine that the communication system 400 is
located in the home living room. The wireless resource
identification module 430 may then identify a first wireless
resource (e.g., a set top box) and a second wireless resource
(e.g., a GSM cellular network) associated with the home living room
location. The communication manager module 440 may then identify
the third configuration profile for communicating with the set top
box utilizing IEEE 802.20 and identify the first configuration
profile for placing a telephone call utilizing the GSM cellular
network.
[0105] Further for example, the communication manager module 440
may be adapted to identify at least one communication protocol (or
standard) of a plurality of communication protocols (or standards)
to utilize for communications. In a non-limiting exemplary
scenario, the communication system 400 (e.g., the wireless
interface modules 410) may be adapted to communicate utilizing a
first communication protocol (e.g., IEEE 802.11), a second
communication protocol (e.g., Bluetooth), a third communication
protocol (e.g., IEEE 802.16) and a fourth communication protocol
(e.g., WCDMA). Continuing the exemplary scenario, the location
determination module 420 may determine that the communication
system 400 is located in a particular conference room in a
particular building. The wireless resource identification module
430 may then, for example, identify a first wireless resource
(e.g., a Bluetooth-based wireless LAN access point), a second
wireless resource (e.g., an IEEE 802.16-based video projector) and
a third wireless resource (e.g., a Bluetooth-based audio output
device). Continuing the exemplary scenario, the communication
manager module 440 may then identify the second communication
protocol for communicating with the wireless LAN, the third
communication protocol for communicating with the video projector
and the second communication protocol for communicating with the
audio output device.
[0106] Note that communication protocol (or standard)
identification may also comprise various implementation details
associated with a communication protocol. Such protocol
implementation details may, for example and without limitation,
comprise power information, frequency information, secure
communication information, etc. Note also that such information may
vary based on location. For example, different regions may have
different respective maximum power limits associated with the IEEE
802.11 standard and/or may require operation in different
respective frequency bands. Accordingly, implementing a first
protocol at a first location may be different from implementing the
first protocol at a second location.
[0107] In general, the communication manager module 440 may be
adapted to identify respective manner(s) of communicating with the
identified wireless resources(s). Accordingly, the scope of various
aspects of the present invention should not be limited by
characteristics of any particular manner of, or mechanism for,
identifying a manner of communicating.
[0108] The communication manager module 440 may (e.g., utilizing
the wireless interface modules 410 be adapted to communicate with
the identified wireless resources (e.g., as identified by the
wireless resource identification module 430) in particular
respective manners (e.g., as identified by the communication
manager module 440). The communication manager module 440 may be
adapted to communicate with the identified wireless resources in
any of a variety of manners (e.g., utilizing the wireless interface
modules 410).
[0109] The communication system 400 may generally perform any of a
variety of types of additional processing. For example, the
communication system 400 (or a module thereof) may be adapted to
maintain wireless resource database information. Also for example,
the location determination module 420 may be adapted to
re-determine location of the communication system 400 and continue
operation. Further for example, the communication system 400 may be
adapted to receive operational information from a user (e.g.,
through the user interface modules 450). Still further for example,
the wireless resource identification module 430 may be adapted to
periodically perform searches for unknown wireless resources and/or
verifying the existence and/or availability of known wireless
resources.

comprising GSM/GPRS/EDGE, CDMA/WCDMA, TDMA/PDC, Bluetooth, IEEE
802.11, UWB, IEEE 802.15, IEEE 802.16, IEEE 802.20, DVB-H, etc.
[0114] The exemplary communication system 500 may also comprise a

[0115] The exemplary communication system 500 may additionally

obtained through user interaction, etc.
[0116] The exemplary communication system 500 may further comprise
a communication manager module 540, which may share any or all
characteristics with the communication manager module 440
illustrated in FIG. 4 and discussed previously. For example, the
communication manager module 540 may be adapted to identify manners
of communication with various wireless resources and to manage
communication with various wireless resources. For example, the
communication manager module 540 may be adapted to identify various
radios, radio configurations, protocols and/or standards to utilize
for communication with various wireless resources.
[0117] The exemplary communication system 500 may, for example,
comprise a general processor or digital signal processor 560 and a
memory 570. The processor 560 and memory 570 may be adapted to
implement various aspects of the present invention with the

[0118] Also for example, as discussed previously, various aspects
of wireless resource identification may involve utilizing memory

maintaining a wireless resource database). The memory 570 may be
utilized for such a purpose.
[0119] The exemplary system 500 further includes one or more user
