RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 15/235,813 filed on Aug. 12, 2016, that is a
continuation of U.S. patent application Ser. No. 14/067,576 filed
on Oct. 30, 2013, that is a continuation of U.S. patent application
Ser. No. 11/277,951 filed on Mar. 30, 2006, all of which are hereby

FIELD OF THE INVENTION
[0002] The present invention relates to electronic devices, and
means for data communication using electronic devices. More
particularly, the invention relates to a user friendly solution for
communicating data using an electronic device with a Near Field
Communication interface.
BACKGROUND
[0003] Digital mobile telephony has become one of the most
important ways of communicating, both for making voice calls and
exchanging data. For the mere purpose of exchanging data, network
protocols have also evolved for use by means of computers, e.g. in
Wireless Local Area Networks (WLAN).
[0004] A system for short range radio communication between
electronic devices has also been provided under the name
Bluetooth.TM.. Bluetooth is basically a wireless personal area
network technology, which is an open standard for short-range
transmission of digital voice and data between predominantly mobile
devices, and supports point-to-point and multipoint applications.
Bluetooth typically provides up to 720 Kbps data transfer within a
range of 10 meters and up to 100 meters with a power boost.
Bluetooth uses omni-directional radio waves that can transmit
through walls and other non-metal barriers in the unlicensed 2.4
GHz band.
[0005] In recent years, a new technology for even shorter range
communication in the mobile telecommunications market has evolved,
based on radio frequency identification (RFID) and generally
referred to as Near Field Communication (NFC). NFC has been
characterized as the intuitive link between consumer devices, and
facilitates short-range communication between electronic devices,
such as mobile phones, Personal Digital Assistants (PDA), computers
and advanced consumer electronics, via a fast and easy wireless
connection. The NFC technology has been developed jointly by Royal
Philips Electronics and Sony Corporation, and enables consumers to
securely exchange and store all kinds of information including
ownership rights, credit card numbers, coupons, membership
messages, pictures and MP3 files, simply by bringing two devices
close together. NFC may act as a secure smart key for access to
content and services such as cashless payment, ticketing, online
entertainment and access control, and can also be used to
automatically configure and initiate wireless connections under
other protocols, such as Bluetooth or Wi-Fi, enabling devices to
communicate at longer ranges or transfer data at higher rates.
[0006] Typically, NFC provides a contactless proximity interaction
over a few centimeters which simplifies the issue of
identification, as there is less confusion when devices can only
connect with their immediate neighbors. A number of NFC trials are
currently taking place around the globe. Since December 2005, a
major NFC trial has been underway at the Philips Arena stadium in
Atlanta, Ga., allowing sports fans to easily buy goods at
concession stands and apparel stores. Additionally they are able to
access and download mobile content such as ring tones, wallpapers,
screensavers and clips from favorite players and artists by holding
their NFC-enabled phone in front of a poster embedded with an NFC
tag.
[0007] NFC runs on the 13.56 MHz frequency band with a read and
write range of up to 10 centimeters. It operates at data rates of
106 kbits/s and 212 kbits/s, although higher transmission speeds
can be achieved between dedicated NFC devices, initially up to 424
kbits/s with potential for higher bit rates. As NFC devices can
operate in an active or passive mode, the technology also offers a
unique link to the contactless smart card world as it is compatible
with the broadly established contactless smart card infrastructure
based on ISO 14443 A (i.e. Philips MIFARE.RTM. technology), as well
as Sony's FeliCa.TM. card used for electronic ticketing in public
transport and for payment applications. It also allows mobile
devices to communicate in passive mode, saving power and extending
battery life. Targeted to become a widely adapted contactless
infrastructure, NFC is already standardized according to globally
accepted standardization bodies, such as ISO (18092), ECMA (340)
and ETSI. As is often the case with the devices sharing a single RF
band, the communication is half-duplex. The devices implement the
"listen before talk" policy--any device must first listen on the
carrier and start transmitting a signal only if no other device can
be detected transmitting. Furthermore, the NFC protocol
distinguishes between the Initiator and the Target of the
communication. Any device may be either an Initiator or a Target.
The Initiator, as follows from the name, is the device that
initiates and controls the exchange of data. The Target is the
device that answers the request from the Initiator. The NFC
protocol also distinguishes between two modes of operation: Active
mode and Passive mode. All devices support both communication
modes. The distinction is as follows:
[0008] In the Active mode of communication both devices generate
their own RF field to carry the data.
[0009] In the Passive mode of communication only one device
generates the RF field while the other device uses load modulation
to transfer the data. The protocol specifies that the Initiator is
the device responsible to generate the RF field.
SUMMARY OF THE INVENTION
[0010] Many electronic devices of today are capable of exchanging
data with other devices in several different ways. A mobile phone,
for instance, is typically configured to communicates with a radio
communications network such as a WCDMA network, for voice calls and
for downloading or streaming data from content servers. A Bluetooth
chip is often also included, enabling short range communication.
NFC technology provides yet another means for communication using
the same electronic device. Even though the different communication
technologies are intended to supplement each other, it may be
difficult for the average user with limited technical skills to
appropriately handle an electronic device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0068] The present invention relates to communication of data in
electronic devices, including sending and acquiring data. The
electronic device as such may take the shape of e.g. a personal
computer, a digital camera, a media player, or a PDA. However, as a
best mode of the invention presently known, the invention will
mainly be described herein as incorporated in the field of
telecommunications, and the electronic device will therefore
occasionally be referred to as a mobile phone. It should be noted,
though, that the borders between what can be considered a mobile
phone, a portable laptop computer, a PDA, becomes less and less
clear since many electronic devices include corresponding
functions, even though focus is on different functionalities in the
different categories of electronic devices. Furthermore, it should
be emphasized that the term comprising or comprises, when used in
this description and in the appended claims to indicate included
features, elements or steps, is in no way to be interpreted as
excluding the presence of other features elements or steps than
those expressly stated.
[0069] Exemplary embodiments will now be described with references
made to the accompanying drawings.
[0070] FIG. 1 schematically illustrates a pair of electronic
devices 10, 30 in the form of mobile phones, the one to the left
being electronic device 10. Details of the mobile phone 10 as such
are of little importance to the invention, but for the sake of
clarity it should be mentioned that phone 10 comprises a support
structure 11 including a chassis and a cover, directly or
indirectly supporting the other components of the terminal. Phone
10 is further devised with a user interface comprising a keypad 12
and a touch-sensitive display 13, as well as a microphone 14 and a
speaker 15. Though not shown in FIG. 1, phone 10 further comprises
a signal transceiver, including an antenna and radio transmission
and reception electronics, for communicative connection to a base
station of a communications network, such as a WCDMA network. A
power supply is preferably included in phone 10 in the form of a
battery, and a cable socket for connection to a mains outlet via a
transformer. Phone 10 is also devised with a computer system,
including a microprocessor with associated memory and software,
configured to carry out the tasks of signal processing and data
handling in the phone. All of these features are, as such, well
known in the field of telecommunication devices.
[0071] FIG. 3 is a block diagram, schematically representing mobile
phone 10 of FIG. 1. A control unit 16 represents the microprocessor
of the computer system configured to control the processes carried
out within mobile phone 10. In order for a user to control and
monitor the processes carried out under control of control unit 16,
the user interface, including keypad 12, display 13, microphone 14
and speaker 15, is communicatively connected to control unit 16. A
data memory 19 is also connected to control unit 16, for storing
data code in files representing e.g. images, games, music, video
and so on. In the present embodiment, where the electronic device
is a mobile phone, control unit 16 is also connected to a signal
transceiver 20, e.g. including an antenna for wireless
communication with a base station in a radio network.
[0072] In accordance with the invention, the electronic device here
provided in the shape of mobile phone 10 further comprises a
contact-free near field communication interface, using
electromagnetic waves. The embodiments described herein make use of
the Near Field Communication (NFC) technology referred to above.
The NFC technology is as such standardized and described in the
related literature, and will therefore not be described in detail
herein, as it lies within the field of knowledge of the skilled
person. However, it may be mentioned that the published European
patent application EP 1 431 904 A2 describes both the function and
structure of an NFC apparatus, including how an NFC apparatus is
configured to communicate data with another NFC apparatus, which
may be an NFC tag, by transmitting an electromagnetic wave signal
using an antenna, and by detecting a modulated electromagnetic wave
signal received in response from the NFC tag. For this reason, EP 1
431 904 A2 is incorporated herein by reference.
[0073] In order to carry out near field communication, the NFC
interface of phone 10 therefore comprises an antenna 18 devised for
transmission and reception of electromagnetic waves, connected to a
circuit 17. Circuit 17 comprises an electromagnetic wave generator
for forming a radio frequency field, connected to the antenna, and
a modulator connected to the antenna 18, for sending data by
modulating electromagnetic waves. The circuit 17 may also comprise
a demodulator connected to the antenna for acquiring data modulated
in an electromagnetic wave. The specific structure and function of
the NFC interface circuitry is not crucial to the present
invention, but the NFC interface may e.g. be configured in
accordance with the previously mentioned RFID, MIFARE or FeliCa
technologies. Antenna 18 is preferably a closed loop coil, as
illustrated. The NFC interface is usable for interacting with
external NFC devices placed in proximity to antenna 18, such as
below phone 10 or beside phone 10 as shown in FIGS. 1 and 2.
[0074] The invention relates to combined use of the user interface
and the communication interface of an electronic device, here
embodied as mobile phone 10. As previously noted, modern day mobile
phones are often equipped to provide communication capabilities for
interaction in many different communication systems, including long
range radio communication in a radio network, such as a WCDMA or
GSM network, Bluetooth for direct short range communication with
other devices, possibly WLAN communication, as well as being
devised for near field communication. The different communication
protocols are suitable for different purposes, and new means for
communication are continuously developed. NFC has a benefit in its
short range, typically 0-20 cm, in that it is generally clear which
two devices are arranged to communicate. NFC is a powerful
technology for natural interaction by gestures. However, it is not
always obvious to a user what will happen when touching or
approaching an NFC tag or another electronic device equipped with
an NFC interface. For one thing, there are many different actions
that can be performed on a certain object. For instance, when a
picture is shown on display 13, does positioning of the phones NFC
interface adjacent to another devices NFC interface mean Send or
Move or Show Temporarily or Hand Over Slideshow Control, etc? As
another example, there may be several different objects shown on
display 13, e.g. a plurality of pictures. Even if the action to
carry out, such as Send, has been made clear by means of an input
command, it is still not obvious which picture should be sent.
[0075] In accordance with the invention, this general problem is
solved by combining the detection of a present NFC connection with
another NFC device, with simultaneous detection of a command
entered on the touch-sensitive display 13, as a trigger to execute
an NFC communication action.
[0076] FIG. 1 illustrates a scenario according to an embodiment of
the invention, where phone 10 is placed in contact with or adjacent
to a second NFC device 30. In the drawings, second NFC device 30 is
also illustrated as a mobile phone, but it should be noted that
second device 30 may be any kind of electronic device containing an
NFC interface, and even a simple NFC tag. Second electronic device
30 will therefore not be described in any greater detail. The
embodiment of FIG. 1 relates to a sharing scenario where the user
of phone 10 wants to send a picture to second device 30. A
plurality of objects 131-134, in this case pictures, are shown on
display 13. In the illustrated embodiment there are four pictures
shown but there may of course be more or less than that. The
displaying of these pictures may be activated responsive to the NFC
interface 17, 18 detecting the presence of second device 30,
wherein displaying of images stored in a memory 19 is set as a
default action to be carried out when a second NFC device is
detected. Alternatively, a command has been entered by the user of
phone 10, by means of an input key of keypad 12 or on
touch-sensitive display 13, to display all pictures of memory 19,
or all pictures of a certain folder in memory 19. In a state of the
art mobile phone, there are a number of different actions that may
be carried out when one or more pictures are shown on display 13.
Using a soft key function, you may e.g. edit the picture, rename
it, use it as background, send it and so on. In the present
embodiment, though, the simultaneous presentation of the pictures
and detection of an established communication link to second device
30, renders a predetermined executable action to be ready to be
carried out, and preferably also presentation of a label 135 on
display 13 indicating the action, namely Send Picture. By touching
e.g. object 131, the first picture, on display 13 while an
established communication link to second device 30 is detected, the
NFC interface is triggered to execute the command on that object,
i.e. to send picture 131. In a state of the art solution for
handling pictures in a mobile phone, an input send command is
followed by the user being presented a menu with different
selectable communication means, such as email, MMS, Bluetooth, IR,
and so on. In accordance with the presented embodiment of the
invention, this step is no longer necessary in the presence of a
second NFC device 30, as NFC will automatically be selected.
Furthermore, NFC has been proposed to operate with focus on
performing automatic communication tasks when an NFC device is
placed in communication range with a second NFC device, for sending
or downloading of data. This may not be appropriate when there are
many data items, such as pictures, that may be shared, and the user
only wants to share one or a few of those objects. As opposed to
these prior art procedures, simultaneous touching of the intended
object 131 and detection of a communicative connection acts as a
confirmation process that data representing that object is to be
sent using NFC to the currently connected second device 30. The
preferred embodiment of this invention involves the presentation of
a plurality of objects which are separately selectable by touching,
as shown in FIG. 1, but the invention also works with only one
presented object. The embodiment of FIG. 1 has been described for
pictures, but may of course as work just as well for other types of
data items, such as games, ring tones, video clips and so on, which
are then preferably represented by objects in the form of icons or
labels.
[0077] FIG. 2 illustrates a second embodiment, in which display 13
is filled with a plurality of different objects 231-234
representing different commands. Again, it may be a default setting
that this screen is to be presented when a second NFC device 30 is
detected to be in communicative connection with phone 10.
Alternatively, this screen may be selected by means of a separate
command entered by a user of phone 10 using an input key. The
different objects preferably represent some of the most commonly
used commands for use in near field communications. As an example,
object 231 may represent music, and include a label stating "Share
Favorite Music". Simultaneous touching of object 231 and detection
of a present communicative connection between the NFC interface of
phone 10 with a second NFC device 30 will then trigger sending of a
music file or playlist stored in memory 19 to the currently
connected second device 30 using NFC. A second object 232 may
represent a business card, and include a label stating "Send
Business Card". Simultaneous touching of object 232 and detection
of a present communicative connection between the NFC interface of
phone 10 with a second NFC device 30 will then trigger sending of
an electronic business card for the user of phone 10 to the
currently connected second device 30 using NFC. Other possible
objects presentable in a common screen may represent commands such
as share a contact, a picture, or a ring signal etc, touching of
which may lead to a list where a certain item within the category
in question may be selected by touching or by using a navigation
tool, which contact is then sent to the second device 30 using NFC.
In another embodiment, though, the commands represented in the
presented objects are all specific, meaning that one touch of a
command uniquely identifies and triggers the action to be executed
without having to make a new selection. A label 235 may also be
presented, in this case Command, on display 13.
[0078] In order to indicate that there is an established
communication connection between phone 10 and second device 30, a
visual indicator may be employed, functioning to provide a visual
indication of an ongoing connection. Such a visual indication may
be given by a separate photo diode on phone 10 (not shown), or by
an indication on display 13.
[0079] By combining a touch-sensitive display function with
detection of NFC communication connection, the ease of use of NFC
communication is enhanced. Making e.g. a plurality of selectable
commands visible on the display decreases the invisibility of NFC
interaction, so that the user will sure of what actually happens in
the interaction with another NFC device. Furthermore, there will be
fewer accidental interactions when the phone is positioned in
communication range with other NFC devices, since the user needs to
touch an object on the screen to trigger a communication action.
This increases the control over the near field communication
process. Furthermore, the present invention provides the ease of
use sought for by the market, in a time where different types of
data communication not only provides extended capabilities but also
requires a higher degree of knowledge from the users.
[0080] The principles of the present invention have been described
in the foregoing by examples of embodiments or modes of operations.
However, the invention is not limited to the particular embodiments
discussed above, which should be regarded as illustrative rather
than restrictive, and it should be appreciated that variations may
be made in those embodiments by persons skilled in the art, without
departing from the scope of the present invention as defined by the
appended claims.
