[0037] 6. Conclusion
[0038] <<1. Configuration of Communication System>>
[0039] Firstly, a configuration of a communication system according
to an embodiment of the present disclosure will be described with
reference to FIGS. 1-5.
[0040] <1.1. General Configuration of Communication
System>
[0041] A general configuration of a communication system 1
according to this embodiment will be described with reference to
FIG. 1. FIG. 1 is an illustrative diagram illustrating an example
of the general configuration of the communication system 1
according to this embodiment. Referring to FIG. 1, the
communication system 1 includes a base station 10, a management
node 20, and a communication apparatus 100.
[0042] The base station 10 performs wireless communication with an
apparatus located within the communication area (i.e., a cell) of
the base station 10. For example, when the communication apparatus
100 is located within the communication area, the base station 10
performs wireless communication with the communication apparatus
100.
[0043] The management node 20 performs management involved with
wireless communication. For example, the management node 20 is a
node in a mobile communication network including the base station
10. More specifically, for example, the management node 20 is a
core network node located within a core network 30.
[0044] The communication apparatus 100 performs wireless
communication. For example, the communication apparatus 100, when
located within the communication area (i.e., a cell) of the base
station 10, performs wireless communication with the base station
10. Also, for example, the communication apparatus 100 performs
wireless communication without routing via the base station 10.
[0045] According to this embodiment, the communication apparatus
100 generates information related to data which is wirelessly
transmitted or received without being routed via the base station
10 (hereinafter referred to as "data-related information"), and
transmits the data-related information to a node which is not
involved with the transmission or reception of the data. Note that
the node is the management node 20. Also, the communication
apparatus 100 is involved with the transmission or reception of the
data.
[0046] <1.2. Specific Examples of Communication
Apparatus>
[0047] Next, specific examples of the communication apparatus 100
will be described with reference to FIGS. 2-4.
First Example
[0048] In a first example, the communication apparatus 100 performs
D2D communication, and the data wirelessly transmitted or received
without being routed via the base station 10 is data which is
transmitted or received by D2D communication. This example will now
be more specifically described with reference to FIG. 2.
[0049] FIG. 2 is an illustrative diagram for describing a first
specific example of the communication apparatus 100 according to
this embodiment. Referring to FIG. 2, in addition to the base
station 10 and the management node 20, the communication apparatus
100, which is a terminal apparatus, and a terminal apparatus 41 are
shown. In this example, the communication apparatus 100 performs
D2D communication with the terminal apparatus 41. The communication
apparatus 100 also generates data-related information related to
data transmitted or received by D2D communication, and transmits
the data-related information to the management node 20. Note that
the communication apparatus 100 may be either a source of data in
D2D communication or a destination of data in D2D
communication.
[0050] As a result, for example, management involved with D2D
communication can be performed.
Second Example
[0051] In a second example, the communication apparatus 100
performs wireless communication within a localized network (LN),
and the data wirelessly transmitted or received without being
routed via the base station 10 is data transmitted or received
within an LN. This example will now be more specifically described
with reference to FIG. 3.
[0052] FIG. 3 is an illustrative diagram for describing a second
specific example of the communication apparatus 100 according to
this embodiment. Referring to FIG. 3, in addition to the base
station 10 and the management node 20, the communication apparatus
100, a terminal apparatus 43, and a terminal apparatus 45 which are
a terminal apparatus, are shown. In this example, the communication
apparatus 100, the terminal apparatus 43, and the terminal
apparatus 45 form an LN, and perform wireless communication within
the LN. The communication apparatus 100 generates data-related
information related to data transmitted or received within the LN,
and transmits the data-related information to the management node
20. For example, the communication apparatus 100 is a master node
which performs control of wireless communication within the LN
(e.g., scheduling of wireless communication within the LN, etc.).
In this case, the terminal apparatus 43 and the terminal apparatus
45 are a slave node which performs wireless communication under the
control of the master node. Note that when two slave nodes (the
terminal apparatus 43 and the terminal apparatus 45) transmit and
receive data, the communication apparatus 100 acquires information
related to data transmitted or received from one of the two slave
nodes.
[0053] As a result, for example, management involved with wireless
communication within an LN can be performed.
[0054] Although an example in which the communication apparatus 100
is a master node has been described, this embodiment is not limited
to this example. For example, the communication apparatus 100 may
be a slave node instead of a master node. In this case, the
communication apparatus 100 may be a slave node which is a source
of data, or a slave node which is a destination of data.
Third Example
[0055] In a third example, the communication apparatus 100
communicates with another apparatus via a relay node, and the data
wirelessly transmitted or received without being routed via the
base station 10 is data which is transmitted or received via a
relay node. This example will now be more specifically described
with reference to FIG. 4.
[0056] FIG. 4 is an illustrative diagram for describing a third
specific example of the communication apparatus 100 according to
this embodiment. Referring to FIG. 4, in addition to the base
station 10 and the management node 20, the communication apparatus
100, which is a terminal apparatus, a relay node 51, and a terminal
apparatus 53 are shown. In this example, the communication
apparatus 100 communicates with the terminal apparatus 53 via the
relay node 51. The communication apparatus 100 generates
data-related information related to data transmitted or received
via the relay node 51, and transmits the data-related information
to the management node 20. Note that the communication apparatus
100 may be either a source of data, or a destination of data in D2D
communication.
[0057] As a result, for example, management involved with wireless
communication via a relay node can be performed.
Fourth Example
[0058] In a fourth example, the communication apparatus 100 is a
relay node, and the data wirelessly transmitted or received without
being routed via the base station 10 is data which is transmitted
or received via a relay node (i.e., the communication apparatus
100). This example will now be more specifically described with
reference to FIG. 5.
[0059] FIG. 5 is an illustrative diagram for describing a fourth
specific example of the communication apparatus 100 according to
this embodiment. Referring to FIG. 5, in addition to the base
station 10 and the management node 20, the communication apparatus
100, which is a relay node, a terminal apparatus 55, and a terminal
apparatus 57 are shown. In this example, the communication
apparatus 100 performs relay between the terminal apparatus 55 and
the terminal apparatus 57. The communication apparatus 100
generates data-related information related to data transmitted or
received via the communication apparatus 100, which is a relay
node, and transmits the data-related information to the management
node 20.
[0060] As a result, for example, management involved with wireless
communication via a relay node can be performed.
[0061] In the foregoing, specific examples of the communication
apparatus 100 have been described with reference to FIGS. 2-5. Note
that, for example, the data wirelessly transmitted or received
without being routed via the base station 10 is transmitted or
received according to the same wireless communication scheme as
that which is used by the base station 10. As an example, the
wireless communication scheme is a multiple access scheme, such as
orthogonal frequency division multiple access (OFDMA), single
carrier frequency division multiple access (SC-FDMA), frequency
division multiple access (FDMA), or time division multiple access
(TDMA). As another example, the wireless communication scheme may
be a multiplexing scheme, such as orthogonal frequency division
multiplexing (OFDM), frequency division multiplexing (FDM), or time
division multiplexing (TDM).
[0062] Instead of a single communication apparatus 100, two
communication apparatuses 100 (or three or more communication
apparatuses 100) may generate data-related information, and
transmit the data-related information to the management node 20.
For example, one communication apparatus 100 which is a source of
data, and another communication apparatus 100 which is a
destination of the data, may each generate data-related information
related to the data, and transmit the data-related information to
the management node 20. As a result, for example, the reliability
of data-related information can be improved. As an example, even if
data-related information transmitted by one communication apparatus
100 fails to reach the management node 20, data-related information
transmitted by another communication apparatus 100 may reach the
management node 20. As another example, even if data-related
information transmitted by one communication apparatus 100 is
information generated without authorization, the data-related
information can be verified using data-related information
transmitted by another communication apparatus 100.
[0063] <<2. Configuration of Communication
Apparatus>>
[0064] Next, an example of a configuration of the communication
apparatus 100 according to this embodiment will be described with
reference to FIGS. 6-8. FIG. 6 is a block diagram illustrating an
example of a configuration of the communication apparatus 100
according to this embodiment. Referring to FIG. 6, the
communication apparatus 100 includes an antenna unit 110, a radio
communication unit 120, a storage unit 130, and a processing unit
140.
[0065] (Antenna Unit 110)
[0066] The antenna unit 110 radiates a signal output by the radio
communication unit 120, as radio waves, into space. The antenna
unit 110 also converts radio waves in space into a signal, and
outputs the signal to the radio communication unit 120.
[0067] (Radio Communication Unit 120)
[0068] The radio communication unit 120 performs wireless
communication. For example, the radio communication unit 120
transmits a signal or receives a signal.
[0069] For example, the radio communication unit 120 performs
wireless communication with the base station 10. More specifically,
for example, the radio communication unit 120, when located within
the communication area (i.e., a cell) of the base station 10,
receives a downlink signal transmitted by the base station 10, and
transmits an uplink signal to the base station 10.
[0070] Also, for example, the radio communication unit 120 performs
wireless communication with a second apparatus other than the base
station 10. More specifically, for example, the radio communication
unit 120 receives a signal from the second apparatus, and transmits
a signal to the second apparatus.
[0071] (Storage Unit 130)
[0072] The storage unit 130 temporarily or permanently stores a
program and data for operating the communication apparatus 100.
[0073] (Processing Unit 140)
[0074] The processing unit 140 provides various functions of the
communication apparatus 100. The processing unit 140 includes an
information generation unit 141 and a transmission control unit
143.
[0075] (Information Generation Unit 141)
[0076] The information generation unit 141 generates information
related to data (i.e., data-related information) which is
wirelessly transmitted or received without being routed via the
base station 10.
[0077] Information for Charging
[0078] In a first example, the data-related information is
information for charging for the transmission or reception of the
data.
[0079] Destination and Destination
[0080] For example, the data-related information contains
information indicating at least one of the source and destination
of the data. More specifically, for example, the data-related
information is addresses (e.g., Internet protocol (IP) addresses,
media access control (MAC) addresses, etc.) of the source and
destination of the data, or other identification information of the
source and destination of the data. Such information can, for
example, be used to identify an apparatus or user to be
charged.
[0081] Amount of Radio Resources/Amount of Data
[0082] Amount of Radio Resources
[0083] For example, the data-related information contains
information indicating the amount of radio resources used for the
transmission or reception of data. More specifically, for example,
the data-related information contains, as the information
indicating the amount of radio resources, the number of resource
blocks, the number of slots, the number of sub-frames, and the
like. Such information can, for example, be used to charge on the
basis of the amount of radio resources used.
[0084] Amount of Data
[0085] Note that the data-related information may contain
information indicating the amount of data instead of or in addition
to the information indicating the amount of radio resources. More
specifically, for example, the data-related information may
contain, as the information indicating the amount data, information
indicating a data size, the amount of packets, etc. Such
information can, for example, be used to charge on the basis of the
amount of data transmitted or received.
[0086] Case Where Communication Error Occurs
[0087] A communication error (e.g., an error on a physical link)
may occur during transmission or reception of data. Therefore,
there may be a number of techniques of calculating the amount of
radio resources or the amount of data.
[0088] For example, in a first calculation technique, the amount of
all radio resources used for transmission or reception of data (or
the amount of all data transmitted or received) is calculated
irrespective of whether a communication error occurs. Thereafter,
data-related information containing information indicating the
amount of all radio resources (or the amount of all data) is
generated.
[0089] For example, in a second calculation technique, the amount
of radio resources used when a communication error does not occur
(or the amount of data transmitted or received when a communication
error does not occur) is calculated. Thereafter, data-related
information containing information indicating the radio resource
amount (or the data amount) is generated. According to the second
calculation technique, for example, a situation where the amount of
charge exceeds what is expected by the user, due to the occurrence
of a communication error, can be avoided.
[0090] When the second calculation technique is employed, the
scheme of retransmission control (e.g., hybrid automatic
repeat-request (HARQ)) or cyclic redundancy check (CRC) may be
utilized in order to calculate the radio resource amount or the
data amount, for example.
[0091] For example, the communication apparatus 100, when being a
source of data, calculates the amount of radio resources on the
basis of ACK/NACK of HARQ. Specifically, the communication
apparatus 100, when receiving ACK, adds the amount of radio
resources used in transmission of data corresponding to the ACK, to
the calculated amount of radio resources. Meanwhile, the
communication apparatus 100, when receiving NACK, does not add the
amount of radio resources used in transmission of data
corresponding to NACK, to the calculated amount of radio resources.
The communication apparatus 100, when receiving neither ACK nor
NACK, does not add the amount of radio resources used in
transmission of corresponding data, to the calculated amount of
radio resources. Although an example of the amount of radio
resources has been described, the amount of data is calculated in a
similar fashion.
[0092] For example, the communication apparatus 100, when being a
destination of data, calculates the amount of radio resources on
the basis of the result of error detection by CRC. Specifically,
when an error has not been detected by CRC (i.e., CRC is
successful), the communication apparatus 100 adds the amount of
radio resources used in transmission of data corresponding to the
CRC, to the calculated amount of radio resources. Meanwhile, when
an error has been detected by CRC, the communication apparatus 100
does not add the amount of radio resources used in transmission of
data corresponding to the CRC, to the calculated amount of radio
resources.
[0093] Note that data-related information is generated, and
transmitted as described below, each time it is found that a
communication error has not occurred. For example, each time the
communication apparatus 100 receives ACK, the communication
apparatus 100, when being a source of data, may calculate the
amount of radio resources used in transmission of data
corresponding to the ACK (or the amount of the data), and generate
and transmit data-related information containing information
indicating that amount. Alternatively, each time CRC is successful,
the communication apparatus 100, when being a destination of data,
calculates the amount of radio resources used in transmission of
data corresponding to the CRC (or the amount of the data), and
generate and transmit data-related information containing
information indicating that amount.
[0094] Others
[0095] Note that the data-related information may contain other
information. As an example, the data-related information may
contain information related to an application corresponding to the
data (e.g., information indicating the type of the application,
information indicating the application, etc.). As another example,
the data-related information may contain a communication form
(e.g., D2D communication, communication within an LN, relay,
etc.).
[0096] As described above, for example, the data-related
information is information for charging for the transmission or
reception of the data. Such data-related information can, for
example, be used to manage charging for wireless communication
which is performed without routing via the base station 10.
[0097] Information for Lawful Interception (LI)
[0098] As a second example, the data-related information is
information for lawful interception (LI).
[0099] Destination and Destination
[0100] For example, the data-related information contains
information containing at least one of the source and destination
of the data. More specifically, for example, the data-related
information is addresses (e.g., an IP address, a MAC address, etc.)
of the source and destination of the data, or other identification
information of the source and destination of the data. Such
information can, for example, be used to identify an apparatus or
user which transmits or receives data.
[0101] Data
[0102] For example, the data-related information contains the data
(i.e., data transmitted or received without being routed via the
base station 10). Such information can, for example, be used to
check transmitted or received data itself
[0103] Others
[0104] Note that the data-related information may contain other
information. As an example, the data-related information may
contain information related to an application corresponding to the
data. As another example, the data-related information may contain
information indicating a communication form.
[0105] As described above, for example, the data-related
information is information for LI. Such data-related information
can, for example, be used to perform lawful interception (LI) for
wireless communication which is performed without routing via the
base station 10. Note that, for example, when two apparatus
transmit and receive data, then if at least one of the two
apparatuses is an apparatus for LI, information (data-related
information) for LI is generated and transmitted.
[0106] Unit of Generation of Data-Related Information
[0107] The information generation unit 141 may generate the
data-related information in various units. For example, the
information generation unit 141 may generate the data-related
information on a packet-by-packet basis, or may generate the
data-related information about data which is transmitted or
received during a predetermined period of time, or may generate the
data-related information which is transmitted or received during a
period of time between the start and end of a session (or
connection).
[0108] (Transmission Control Unit 143)
[0109] The transmission control unit 143 controls transmission of
the data-related information to a node which is not involved in the
transmission or reception of the data (i.e., data transmitted or
received without being routed via the base station 10).
[0110] Node Not Involved in Transmission or Reception of Data
[0111] The node which is not involved in the transmission or
reception of the data (i.e., a node which is a destination of the
data-related information) is the management node 20.
[0112] As described above, in a first example, the data-related
information is information for charging for the transmission or
reception of the data. In this case, the management node 20 is a
node which manages charging. More specifically, for example, the
management node 20 is a policy and charging rule function
(PCRF).
[0113] Also, as described above, in a second example, the
data-related information is information for lawful interception
(LI). In this case, the management node 20 is a node for performing
a process for LI. The process includes, for example, storing the
information for LI to a storage device. The storage device may be a
storage device included in the management node 20, or a storage
device included in another node. As an example, the management node
20 is a packet data network (PDN) gateway (P-GW).
[0114] Path for Transmission of Data-Related Information
[0115] For example, the data-related information is transmitted to
the management node 20 via the base station 10. A specific example
of this will now be described with reference to FIG. 7.
[0116] FIG. 7 is an illustrative diagram for describing a first
example of a transmission path for data-related information.
Referring to FIG. 7, the base station 10, the management node 20,
and the communication apparatus 100 are shown. In this example, the
management node 20 is located in the core network 30, and the
communication apparatus 100 transmits the data-related information
to the management node 20 via the base station 10 and the core
network 30.
[0117] Note that the transmission path in this embodiment is not
limited to this example. For example, the data-related information
may be transmitted to the management node 20 without being routed
via the base station 10 instead of being transmitted to the
management node 20 via the base station 10. A specific example of
this will now be described with reference to FIG. 8.
[0118] FIG. 8 is an illustrative diagram for describing a second
example of the transmission path for the data-related information.
Referring to FIG. 7, the base station 10, the management node 20,
and the communication apparatus 100 are shown. In this example, the
management node 20 is located in the core network 30, and the
communication apparatus 100 transmits the data-related information
to the management node 20 via an external network 60 and the core
network 30. The external network 60 includes, for example, the
Internet. As an example, the communication apparatus 100 connects
to a wired LAN or a wireless LAN, and transmits the data-related
information to the management node 20 via the Internet.
[0119] Specific Examples of Control
[0120] As an example, as control of transmission of the
data-related information, the transmission control unit 143
generates one or more packets each containing a portion or the
entirety of the data-related information, which are to be sent to
the management node 20. Thereafter, the transmission control unit
143 causes the radio communication unit 120 to transmit the one or
more packets.
[0121] As another example, the transmission control unit 143 may
generate control information for a mobile communication network
containing the data-related information, and cause the radio
communication unit 120 to transmit the control information.
[0122] As still another example, the transmission control unit 143
may trigger transmission of the data-related information.
Specifically, the transmission control unit 143 may instruct
another component (e.g., another component included in the
processing unit 140) of the communication apparatus 100 to transmit
the data-related information.
[0123] The data-related information is thus generated and
transmitted. As a result, for example, management involved with
wireless communication without routing via the base station 10 can
be performed.
[0124] <<3. Flow of Process>>
[0125] Next, examples of the process according to this embodiment
will be described with reference to FIGS. 9-12.
[0126] (Flow of Entire Process)
[0127] First Example
[0128] FIG. 9 is a sequence diagram illustrating a first example of
a general flow of the entire process according to this embodiment.
This process is performed after transmission or reception of data
without routing via the base station 10.
[0129] Initially, the communication apparatus 100 generates
information related to data (i.e., data-related information) which
is wirelessly transmitted or received without being routed via the
base station 10 (S310).
[0130] Thereafter, the communication apparatus 100 transmits the
data-related information to the management node 20, and the
management node 20 receives the data-related information
(S320).
[0131] Thereafter, the management node 20 executes a management
process using the data-related information (S400).
[0132] Second Example
[0133] FIG. 10 is a sequence diagram illustrating a second example
of a general flow of the entire process according to this
embodiment. The process is executed after transmission or reception
of data without routing via the base station 10.
[0134] Initially, a communication apparatus 100A and a
communication apparatus 100B each generate information related to
data (i.e., data-related information) which is wirelessly
transmitted or received without being routed via the base station
10 (S330, S340).
[0135] Thereafter, the communication apparatus 100A and the
communication apparatus 100B each transmit the data-related
information to the management node 20, and the management node 20
receives the data-related information (S350, S360).
[0136] Thereafter, the management node 20 executes a management
process using the data-related information (S400).
[0137] (Examples of Management Process)
[0138] First Example: Charging
[0139] FIG. 11 is a flowchart illustrating an example of a general
flow of a first example of the management process according to this
embodiment. The first example of the management process is a
process for charging management.
[0140] Initially, the management node 20 acquires data-related
information transmitted by the communication apparatus 100 (S401).
Thereafter, the management node 20 checks the source and
destination of data which is transmitted or received without being
routed via the base station 10a, an application corresponding to
the data, and the amount of radio resources used in the
transmission or reception of the data (S403, 5405, S407).
[0141] Thereafter, the management node 20, when determining to
update charging information (S409: YES), determines a node for
which charging information is to be updated (S411), and updates the
charging information of the node (S413).
[0142] Also, the management node 20, when determining to update
policy information related to charging (S415: YES), determines a
node for which policy information is to be updated (S417), and
updates the policy information of the node (S419). Thereafter, the
process is ended.
[0143] Second Example: Lawful Interception (LI)
[0144] FIG. 12 is a flowchart illustrating an example of a general
flow of a second example of the management process according to
this embodiment. The second example of the management process is a
process for LI.
[0145] Initially, the management node 20 acquires data-related
information transmitted by the communication apparatus 100
(S431).
[0146] Thereafter, the management node 20 checks the source of data
which is transmitted or received without being routed via the base
station 10 (S433). Thereafter, the management node 20, when
determining that the source is to be subjected to LI (S435: YES),
executes a process requested for the source to be subjected to LI
(S437). The process includes storing information for LI (e.g., the
data and the source and destination of the data, etc.) to a storage
device.
[0147] The management node 20 also checks the destination of the
data (S439). Thereafter, the management node 20, when determining
that the destination is to be subjected to LI (S441: YES), executes
a process requested for the destination to be subjected to LI
(S443). The process includes storing information for LI to a
storage device. Thereafter, the process is ended.
[0148] <<4. Variations>>
[0149] Next, variations according to this embodiment will be
described with reference to FIGS. 13 and 14.
[0150] Frequency Band Used in Transmission of Data and Data-Related
Information
[0151] A frequency band used in wireless communication which is
performed without routing via a base station (e.g., D2D
communication, communication in an LN, etc.) may be the same as or
different from a frequency band used in wireless communication with
a base station. The frequency band is, for example, a component
carrier for a cellular network, a channel for wireless LAN, or the
like.
[0152] In a variation according to this embodiment, a frequency
band used in wireless communication which is performed without
routing via a base station (e.g., D2D communication, communication
in an LN, etc.) (hereinafter referred to as a "first frequency
band") is different from a frequency band used in wireless
communication with a base station (hereinafter referred to as a
"second frequency band")). Moreover, the second frequency band is a
band having lower frequencies than those of the first frequency
band. A specific example of this example will now be described with
reference to FIG. 13.
[0153] FIG. 13 is an illustrative diagram for describing an example
of the frequency bands. Referring to FIG. 13, a frequency band F1
and a frequency band F2 are shown. For example, the frequency band
F1 is a frequency band which is used in wireless communication with
the base station 10, and the frequency band F2 is a frequency band
which is used in wireless communication which is performed without
routing via the base station 10. The frequency band F1 is a band
having lower frequencies than those of the frequency band F2.
[0154] Also, for example, the second frequency band (a band having
higher frequencies) is used to wirelessly transmit or receive data
without routing via the base station 10, and the first frequency
band (a band having lower frequencies) is used to transmit
information related to the data (i.e., data-related information) to
the base station 10.
[0155] As a result, radio resources can be more effectively used.
More specifically, for example, it is assumed that data-related
information is transmitted to a base station which is located in a
relatively far place. Therefore, the use of a band having lower
frequencies (i.e., the first frequency band), which are less
attenuated, may reduce the possibility that a communication error
occurs in transmission of the data-related information. In other
words, radio resources are more effectively used. For example, it
is also assumed that data is transmitted or received between
apparatuses located relatively close to each other. Therefore, for
example, transmission may be performed by using a band having
higher frequencies (i.e., the second frequency band), which are
significantly attenuated. Also, in the high-frequency band, radio
resources having a wider band width can be provided. In other
words, radio resources can be more effectively used.
[0156] Allocation of Radio Resources for Transmission of Data and
Data-Related Information
[0157] Radio resources for transmission of data-related information
(hereinafter referred to as "first radio resources") and radio
resources for transmission of data (hereinafter referred to as
"second radio resources") are allocated (e.g. by the base station
10).
[0158] For example, the first radio resources and the second radio
resources are allocated as a set of radio resources. As a result,
for example, it is not necessary to request allocation of the first
radio resources and allocation of the second radio resources
separately. For example, even when the first radio resources (radio
resources for transmission of data-related information) are not
independently requested, then if the second radio resources (radio
resources for transmission of data) are requested, transmission of
data-related information is allowed. Note that, in this case,
data-related information is generated by the time when allocation
of radio resources is requested.
[0159] Moreover, the first radio resources and the second radio
resources are allocated so that there is a predetermined offset in
time between the first radio resources and the second radio
resources. A specific example of this will now be described with
reference to FIG. 14.
[0160] FIG. 14 is an illustrative diagram for describing an example
of the first radio resources and the second radio resources.
Referring to FIG. 14, the radio resources of the frequency band F1
and the radio resources of the frequency band F2 are shown. For
example, as radio for transmission of data (i.e., the second radio
resources), the radio resources of time T1 of the frequency band F2
are allocated. As radio resources for transmission of corresponding
data-related information (i.e., the first radio resources), the
radio resources of time T2 of the frequency band F1 are allocated.
Here, the time T2 is time later than the time T1 by a predetermined
offset. For example, thus, there is a predetermined offset (T2-T1)
in time between the first radio resources and the second radio
resources.
[0161] Note that the predetermined offset may be represented in
units of sub-frames, slots, or the like in a cellular network. The
predetermined offset may be represented in units of inter-frames
(IF) or the like in a wireless LAN. Alternatively, the
predetermined offset may be represented in units of seconds or the
like. The length of the predetermined offset may, for example, be
previously determined as a fixed value in a communication system,
or may be set as appropriate in a communication system. The
communication apparatus 100 (or other apparatuses) may be notified
of the length of the predetermined offset at any timing (e.g.,
regularly). This notification may be performed by any of broadcast,
multicast, and unicast.
[0162] <<5. Applications>>
[0163] Technology according to the present disclosure is applicable
to various products. For example, a the communication apparatus 100
may be implemented as a mobile terminal such as a smartphone, a
tablet personal computer (PC), a notebook PC, a portable game
terminal, a portable/dongle type mobile router, and a digital
camera, or an in-vehicle terminal such as a car navigation
apparatus. The communication apparatus 100 may also be implemented
as a terminal (that is also referred to as a machine type
communication (MTC) terminal) that performs machine-to-machine
(M2M) communication. Alternatively, the communication apparatus 100
may be implemented as a relay node or an apparatus included in a
relay node. Moreover, at least a portion of the components of the
communication apparatus 100 may be implemented as a module (e.g.,
an integrated circuit module including a single die) mounted on
these terminals or apparatuses.
First Application Example
[0164] FIG. 15 is a block diagram illustrating an example of a
general configuration of a smartphone 900 to which the technology
of the present disclosure may be applied. The smartphone 900
includes a processor 901, a memory 902, a storage 903, an external
connection interface 904, a camera 906, a sensor 907, a microphone
908, an input device 909, a display device 910, a speaker 911, a
radio communication interface 912, one or more antenna switches
915, one or more antennas 916, a bus 917, a battery 918, and an
auxiliary controller 919.
[0165] The processor 901 may be, for example, a CPU or a system on
a chip (SoC), and controls functions of an application layer and
another layer of the smartphone 900. The memory 902 includes RAM
and ROM, and stores a program that is executed by the processor
901, and data. The storage 903 may include a storage medium such as
a semiconductor memory and a hard disk. The external connection
interface 904 is an interface for connecting an external device
such as a memory card and a universal serial bus (USB) device to
the smartphone 900.
[0166] The camera 906 includes an image sensor such as a charge
coupled device (CCD) and a complementary metal oxide semiconductor
(CMOS), and generates a captured image. The sensor 907 may include
a group of sensors such as a measurement sensor, a gyro sensor, a
geomagnetic sensor, and an acceleration sensor. The microphone 908
converts sounds that are input to the smartphone 900 to audio
signals. The input device 909 includes, for example, a touch sensor
configured to detect touch onto a screen of the display device 910,
a keypad, a keyboard, a button, or a switch, and receives an
operation or an information input from a user. The display device
910 includes a screen such as a liquid crystal display (LCD) and an
organic light-emitting diode (OLED) display, and displays an output
image of the smartphone 900. The speaker 911 converts audio signals
that are output from the smartphone 900 to sounds.
[0167] The radio communication interface 912 supports any cellular
communication scheme such as LTE and LTE-Advanced, and performs
radio communication. The radio communication interface 912 may
typically include, for example, a BB processor 913 and an RF
circuit 914. The BB processor 913 may perform, for example,
encoding/decoding, modulating/demodulating, and
multiplexing/demultiplexing, and performs various types of signal
processing for radio communication. Meanwhile, the RF circuit 914
may include, for example, a mixer, a filter, and an amplifier, and
transmits and receives radio signals via the antenna 916. The radio
communication interface 912 may also be a one chip module that has
the BB processor 913 and the RF circuit 914 integrated thereon. The
radio communication interface 912 may include the multiple BB
processors 913 and the multiple RF circuits 914, as illustrated in
FIG. 15. Although FIG. 15 illustrates the example in which the
radio communication interface 912 includes the multiple BB
processors 913 and the multiple RF circuits 914, the radio
communication interface 912 may also include a single BB processor
913 or a single RF circuit 914.
[0168] Furthermore, in addition to a cellular communication scheme,
the radio communication interface 912 may support another type of
radio communication scheme such as a short-distance wireless
communication scheme, a near field communication scheme, and a
radio local area network (LAN) scheme. In that case, the radio
communication interface 912 may include the BB processor 913 and
the RF circuit 914 for each radio communication scheme.
[0169] Each of the antenna switches 915 switches connection
destinations of the antennas 916 among multiple circuits (such as
circuits for different radio communication schemes) included in the
radio communication interface 912.
[0170] Each of the antennas 916 includes a single or multiple
antenna elements (such as multiple antenna elements included in an
MIMO antenna), and is used for the radio communication interface
912 to transmit and receive radio signals. The smartphone 900 may
include the multiple antennas 916, as illustrated in FIG. 15.
Although FIG. 15 illustrates the example in which the smartphone
900 includes the multiple antennas 916, the smartphone 900 may also
include a single antenna 916.
[0171] Furthermore, the smartphone 900 may include the antenna 916
for each radio communication scheme. In that case, the antenna
switches 915 may be omitted from the configuration of the
smartphone 900.
[0172] The bus 917 connects the processor 901, the memory 902, the
storage 903, the external connection interface 904, the camera 906,
the sensor 907, the microphone 908, the input device 909, the
display device 910, the speaker 911, the radio communication
interface 912, and the auxiliary controller 919 to each other. The
battery 918 supplies power to blocks of the smartphone 900
illustrated in FIG. 15 via feeder lines, which are partially shown
as dashed lines in the figure. The auxiliary controller 919
operates a minimum necessary function of the smartphone 900, for
example, in a sleep mode.
[0173] In the smartphone 900 shown in FIG. 15, the information
generation unit 141 and the transmission control unit 143 described
with reference to FIG. 6 may be implemented in the processor 901 or
the auxiliary controller 919. Alternatively, at least a portion of
these components may be implemented in the radio communication
interface 912. As an example, the smartphone 900 may include a
module including the processor 901, the auxiliary controller 919,
and/or a portion (e.g., the BB processor 913) or the entirety of
the radio communication interface 912. In this module, the
information generation unit 141 and the transmission control unit
143 may be implemented. In this case, the module may store a
program for causing the processor to function as the information
generation unit 141 and the transmission control unit 143 (in other
words, a program for causing the processor to execute operations of
the information generation unit 141 and the transmission control
unit 143), and execute the program. As another example, a program
for causing the processor to function as the information generation
unit 141 and the transmission control unit 143 may be installed in
the smartphone 900, and executed by the processor 901, the
auxiliary controller 919, and/or the radio communication interface
912 (e.g., the BB processor 913). As described above, the
smartphone 900 or the module may be provided as an apparatus
including the information generation unit 141 and the transmission
control unit 143, and a program for causing a processor to function
as the information generation unit 141 and the transmission control
unit 143 may be provided. A readable storage medium storing the
program may also be provided.
Second Application Example
[0174] FIG. 16 is a block diagram illustrating an example of a
general configuration of a car navigation apparatus 920 to which
the technology of the present disclosure may be applied. The car
navigation apparatus 920 includes a processor 921, a memory 922, a
global positioning system (GPS) module 924, a sensor 925, a data
interface 926, a content player 927, a storage medium interface
928, an input device 929, a display device 930, a speaker 931, a
radio communication interface 933, one or more antenna switches
936, one or more antennas 937, and a battery 938.
[0175] The processor 921 may be, for example, a CPU or a SoC, and
controls a navigation function and another function of the car
navigation apparatus 920. The memory 922 includes RAM and ROM, and
stores a program that is executed by the processor 921, and
data.
[0176] The GPS module 924 uses GPS signals received from a GPS
satellite to measure a position (such as latitude, longitude, and
altitude) of the car navigation apparatus 920. The sensor 925 may
include a group of sensors such as a gyro sensor, a geomagnetic
sensor, and an air pressure sensor. The data interface 926 is
connected to, for example, an in-vehicle network 941 via a terminal
that is not shown, and acquires data generated by the vehicle, such
as vehicle speed data.
[0177] The content player 927 reproduces content stored in a
storage medium (such as a CD and a DVD) that is inserted into the
storage medium interface 928. The input device 929 includes, for
example, a touch sensor configured to detect touch onto a screen of
the display device 930, a button, or a switch, and receives an
operation or an information input from a user. The display device
930 includes a screen such as a LCD or an OLED display, and
displays an image of the navigation function or content that is
reproduced. The speaker 931 outputs sounds of the navigation
function or the content that is reproduced.
[0178] The radio communication interface 933 supports any cellular
communication scheme such as LET and LTE-Advanced, and performs
radio communication. The radio communication interface 933 may
typically include, for example, a BB processor 934 and an RF
circuit 935. The BB processor 934 may perform, for example,
encoding/decoding, modulating/demodulating, and
multiplexing/demultiplexing, and performs various types of signal
processing for radio communication. Meanwhile, the RF circuit 935
may include, for example, a mixer, a filter, and an amplifier, and
transmits and receives radio signals via the antenna 937. The radio
communication interface 933 may be a one chip module having the BB
processor 934 and the RF circuit 935 integrated thereon. The radio
communication interface 933 may include the multiple BB processors
934 and the multiple RF circuits 935, as illustrated in FIG. 16.
Although FIG. 16 illustrates the example in which the radio
communication interface 933 includes the multiple BB processors 934
and the multiple RF circuits 935, the radio communication interface
933 may also include a single BB processor 934 or a single RF
circuit 935.
[0179] Furthermore, in addition to a cellular communication scheme,
the radio communication interface 933 may support another type of
radio communication scheme such as a short-distance wireless
communication scheme, a near field communication scheme, and a
radio LAN scheme. In that case, the radio communication interface
933 may include the BB processor 934 and the RF circuit 935 for
each radio communication scheme.
[0180] Each of the antenna switches 936 switches connection
destinations of the antennas 937 among multiple circuits (such as
circuits for different radio communication schemes) included in the
radio communication interface 933.
[0181] Each of the antennas 937 includes a single or multiple
antenna elements (such as multiple antenna elements included in an
MIMO antenna), and is used for the radio communication interface
933 to transmit and receive radio signals. The car navigation
apparatus 920 may include the multiple antennas 937, as illustrated
in FIG. 16. Although FIG. 16 illustrates the example in which the
car navigation apparatus 920 includes the multiple antennas 937,
the car navigation apparatus 920 may also include a single antenna
937.
[0182] Furthermore, the car navigation apparatus 920 may include
the antenna 937 for each radio communication scheme. In that case,
the antenna switches 936 may be omitted from the configuration of
the car navigation apparatus 920.
[0183] The battery 938 supplies power to blocks of the car
navigation apparatus 920 illustrated in FIG. 16 via feeder lines
that are partially shown as dashed lines in the figure. The battery
938 accumulates power supplied form the vehicle.
[0184] In the car navigation apparatus 920 shown in FIG. 16, the
information generation unit 141 and the transmission control unit
143 described with reference to FIG. 6 may be implemented in the
processor 921. Alternatively, at least a portion of these
components may be implemented in the wireless communication
interface 933. As an example, the car navigation apparatus 920 may
include a module including the processor 921 and/or a portion
(e.g., the BB processor 934) or the entirety of the radio
communication interface 933. In this module, the information
generation unit 141 and the transmission control unit 143 may be
implemented. In this case, the module may store a program for
causing the processor to function as the information generation
unit 141 and the transmission control unit 143 (in other words, a
program for causing the processor to execute operations of the
information generation unit 141 and the transmission control unit
143), and execute the program. As another example, a program for
causing the processor to function as the information generation
unit 141 and the transmission control unit 143 may be installed in
the car navigation apparatus 920, and executed by the processor 921
and/or the radio communication interface 933 (e.g., the BB
processor 913). As described above, the car navigation apparatus
920 or the module may be provided as an apparatus including the
information generation unit 141 and the transmission control unit
143, and a program for causing the processor to function as the
information generation unit 141 and the transmission control unit
143 may be provided. A readable storage medium storing the program
may also be provided.
[0185] The technology of the present disclosure may also be
implemented as an in-vehicle system (or a vehicle) 940 including
one or more blocks of the car navigation apparatus 920, the
in-vehicle network 941, and a vehicle module 942. Specifically, the
in-vehicle system (or a vehicle) 940 may be provided as an
apparatus including the information generation unit 141 and the
transmission control unit 143. The vehicle module 942 generates
vehicle data such as vehicle speed, engine speed, and trouble
information, and outputs the generated data to the in-vehicle
network 941.
[0186] <<6. Conclusion>>

network (e.g., a base station). Alternatively, a management node
may be a node which is not a node in a mobile communication
network, and is out of a mobile communication network.
[0203] Also, for example, an example in which data-related
information is information for charging for the transmission or
reception of the data, and an example in which data-related
information is information for lawful interception (LI), have been
described. The present disclosure is not limited to this example.
For example, data-related information may be information for other
managements.
[0204] Also, the processing steps in each process in this
specification are not strictly limited to being executed in a time
series following the sequence described in a flowchart. For
example, the processing steps in each process may be executed in a
sequence that differs from a sequence described herein as a
flowchart, and furthermore may be executed in parallel.
[0205] In addition, it is possible to create a computer program for
causing hardware such as a CPU, ROM, and RAM built into a device
according to an embodiment of the present disclosure (a
communication control device or a terminal device) to exhibit
functions similar to each structural element of the foregoing
devices. Also, a storage medium having such a computer program
stored therein may also be provided. Also, an information
processing device (e.g., a processing circuit or chip) equipped
with memory storing such a computer program (e.g., ROM and RAM) and
one or more processors capable of executing such a computer program
(such as a CPU or DSP, for example) may also be provided.
[0206] In addition, the advantageous effects described in this
specification are merely for the sake of explanation or
illustration, and are not limiting. In other words, instead of or
in addition to the above advantageous effects, technology according
to the present disclosure may exhibit other advantageous effects
