To establish near field communications (NFC) with other locally positioned electronic devices, such as a NFC-enabled and/or NFC-compliant electronic devices and the like, the mobile telephone 10 may further include a NFC interface adapter 52. As used herein, the phrases “NFC-enabled” and “NFC-compliant” may be used interchangeably and refer to devices that are capable of communicating with other devices using one or more near field communication protocols. Preferably, the NFC interface adapter 52 is compatible with one or more NFC related protocols and allows the mobile telephone 10 to communicate with other NFC-enabled and/or compliant devices. As used herein, the phrase “near field communication” and its acronym “NFC” fully comprises all of the communication features and functions associated with radio frequency identification (RFID) and any other near field communication protocols.
The mobile telephone 10 may also be configured to operate in a wide area communications system (e.g. 3G, GPRS) (not illustrated). The system can include a server or servers for managing calls, Internet access and/or E-mails placed by and/or destined to the mobile telephone 10, transmitting content (e.g., image files, audio files, video files, etc.) to and/or from the mobile telephone 10 and carrying out any other support functions. The server generally communicates with the mobile telephone 10 via a network and a transmission medium. The transmission medium may be any appropriate device or assembly, including, for example, a communications tower, another mobile telephone, a wireless access point, a satellite, etc. Portions of the network may include wireless transmission pathways.
FIG. 3 illustrates an exemplary near field communication system 60 in accordance with the present invention. The system 60 consists of a mobile telephone 10 and an electronic device 62. The electronic device 62 may be any electronic device having NFC capabilities. For example, the electronic device 62 may be a personal digital assistant (PDA), a personal computer (PC), a mobile telephone, a wristwatch, a pen, or other communication device. The mobile telephone 10 and the electronic device 62 are adapted to perform near field communication based on electromagnetic induction making use of the carrier waves of a single frequency with other NFC apparatuses. The frequency of the carrier waves used by the mobile telephone 10 and the electronic device 62 may be any suitable frequency. For example, one such suitable frequency is 13.56 MHz, which is in the industrial scientific medical (ISM) band.
As one of ordinary skill in the art will appreciate, near field communication means the communication that can be accomplished when the distance “d”, as illustrated in FIG. 3, between communicating apparatuses is several tens of centimeters or less, and it includes the communication accomplished through the contact between communicating apparatuses or between their housings.
The communication system illustrated in FIG. 3 may be used as an IC card system in which one or more of the NFC-compliant devices (e.g. mobile telephone 10 and electronic device 62 function as readers/writers, while the remaining one or more function as IC cards. Generally, NFC-compliant devices permit communication in two communication modes (e.g., active and passive modes) and also permit data transmission at a plurality of transmission rates.
In the passive mode, the mobile telephone 10 may modulate the carrier waves corresponding to the electromagnetic waves that it generates, so as to send data to the electronic device 62. The electronic device 62 generally modulates the carrier waves corresponding to the electromagnetic waves generated by the mobile telephone 10 and sends the resulting information, in the form of a NFC tag to the mobile telephone 10.
In the active mode, mobile telephone 10 and electronic device 62 both modulate the carrier waves corresponding to the electromagnetic waves generated by themselves so as to send information (e.g., NFC tags). When the near field communication based on electromagnetic induction is performed, the apparatus that outputs electromagnetic waves first to initiate the communication and may be said to take the initiative is called an initiator. The initiator transmits a command to a communicating party, and the communicating party sends a response associated with the command so as to establish the near field communication. The communicating party who sends the response to the command received from the initiator is called a target. For example, if mobile telephone 10 begins outputting electromagnetic waves to start communication with the electronic device 62, then the mobile telephone 10 will be the initiator and the electronic device 62 will be the target.
In the passive mode, the mobile telephone 10, which is the initiator, continues outputting electromagnetic waves. The mobile telephone 10 modulates the electromagnetic waves generated by itself so as to send data to the electronic device 62, which is the target. The electronic device 62 carries out load-modulation on the electromagnetic waves output from the mobile telephone 10, which is the initiator, and sends information to the mobile telephone 10.
In the active mode, when the mobile telephone 10, which is the initiator, sends information, it generally first starts outputting electromagnetic waves by itself, and modulates the generated electromagnetic waves so as to send data to the target, i.e., the electronic device 62. The mobile telephone 10 may stop outputting electromagnetic waves after the completion of the transmission of data. When the electronic device 62, which is the target, sends data, it begins outputting electromagnetic waves by itself, and modulates the electromagnetic waves so as to send data to the mobile telephone 10, which is the initiator. The electronic device 62 may stops the output of the electromagnetic waves after the transmission of data is finished.
One of ordinary skill in the art will readily appreciate that the above discussion is exemplary in nature and in no way is intended to limit the scope of the present invention. Likewise, one of ordinary skill in the art will readily appreciate that the NFC tag transmitted from one NFC-compliant device to another may contain a variety of information. Such information may include, for example, a number or identification that is unique to the NFC-adapter, a telephone number, a serial number, a model number, etc.
Aspect of the present invention relate to storing the NFC tag of an electronic device (e.g., electronic device 62) in an electronic phonebook. The step of storing may occur automatically when the electronic device is within the near field communication range of the mobile telephone. In addition, the step of storing may be also manual and/or a combination of automatic and/or manual.
As shown in FIG. 4, a conventional electronic phonebook 70 can accommodate a plurality of contacts, with each of the contacts including a variety of fields. For example, as shown in FIG. 4, the conventional phonebook 70 includes a plurality of contacts. Each contact generally includes one or more associated fields. Such fields may include, for example, entry number, contact name, and one or more telephone numbers, ring tones, pictures, e-mail addresses, home address, electronic business cards and the like. Mobile phone users routinely make use of the phonebook function for convenience. Typically electronic phonebooks organize and display contacts based on when the contact information was entered into the phonebook or organized in alphabetical order based on contact name.
Referring to FIG. 5, an exemplary electronic phonebook 80 in accordance with aspects of the present is illustrated. The electronic phonebook 80 may allow conventional inputting of information for population of the phonebook. For example, the user may manually enter information (e.g., contact name, telephone number, electronic mail address, business card, and the like); the user may also electronically synchronize the electronic phonebook 80 with a remote device (e.g., a personal computer) that contains information for downloading to the electronic phonebook 80.
The electronic phonebook 80 may also use one or more near field communication protocols to populate one or more contacts and/or entries of the electronic phonebook 80. Near field communication may be used to exchange information (e.g., NFC tags, telephone numbers, contact information, electronic business cards, etc.) between mobile telephone 10 and any NFC-compliant device.
An exemplary illustration of an electronic phonebook 80 for storing NFC tags is shown in FIG. 5. As stated above, since NFC tags are generally technical in nature, aspects of the present invention relate to automatically associating the NFC tags with user-friendly information (e.g., contact information) that facilitates identification of the user and/or device when the user of the mobile telephone 10 is within a geographical range of an NFC-compliant device. In some applications, it may be undesirable to allow the user of the electronic phonebook 80 to have access to the NFC tags stored in the electronic phonebook 80. In some advanced technical and/or administrative application, the electronic phonebook application designer may provide the user with access to stored NFC tags in the electronic phonebook 80 (e.g., allowing the user to view the NFC tag on the display 14, allowing the user to organize the contact information based upon the NFC tag, etc.).
An exemplary method 82 in accordance with aspects of the present invention is illustrated. Referring to FIGS. 3 and 6, at step 84, the mobile telephone 10 determines that a NFC-compliant device is present and establishes a near field communication link. One of ordinary skill in the art will readily appreciate that there are a variety of ways to detect presence and/or absence of an NFC-compliant device. All such methods fall within the scope of the present invention.
At step 86, a request for information is transmitted from the mobile telephone 10 to the NFC-compliant device (e.g., electronic device 62). The request is typically transmitted through a NFC adapter (e.g., near field adapter 52) associated with the mobile telephone 10. The request may be sent automatically by continuously transmitting requests until a response is detected, automatically determining the presence of another NFC-compliant device, and/or manually initiated by a user action.
At step 88, the NFC adapter 52 of the mobile telephone 10 (e.g., NFC adapter 52) receives information in response to the request for information from the NFC-compliant electronic device. The received information is in the form of a NFC signal. The received information may include a NFC tag, telephone number and/or any other desired information.
At step 90, the mobile telephone 10 receives a telephone number or other contact information from the NFC-compliant device. As one of ordinary skill in the art will readily appreciate, the step of receiving information in response at step 88 may also include receiving a telephone number or other contact information from the NFC-compliant device.
At step 92, the mobile telephone determines if the telephone number or other contact information is stored in the electronic phonebook 80. If the telephone number or other contact information is stored in the electronic phonebook 80, at step 94, the electronic phonebook stores the NFC tag for the NFC-compliant device and associates the NFC-tag with user-friendly contact information.
Likewise, if the telephone number or other contact information has a different NFC tag associated than the newly received NFC tag, the electronic phonebook 80 may overwrite the previously stored NFC tag with the newly received NFC tag. In this way, the electronic phonebook 80 will maintain the current NFC tag associated with the telephone number and/or other associated contact information.
The exemplary method 82 preferably occurs automatically when the mobile telephone 10 comes within a distance “d” (as denoted in FIG. 3) of another NFC-compliant device. The method may be initiated by any desired mechanism. For example, a request may be sent automatically by continuously transmitting requests until a response is detected, automatically determining the presence and/or absence of another NFC-compliant device, and/or manually initiated by a user action, etc.
It is also preferable that the exemplary method 82 occurs seamlessly and without user intervention. Thus, when the mobile telephone 10 comes within a distance “d” of another NFC-compliant device, the NFC tag associated with the NFC-compliant device is stored in the electronic phonebook 80 and associated with one or more contacts contained in the electronic phonebook 80. Accordingly, the NFC tag received from the NFC-compliant device is associated with user-friendly information that facilitates identification of the user and/or device for future communications.
Another exemplary method 100 in accordance with aspects of the present invention is illustrated in FIG. 7. The method 100 allows two NFC-compliant devices to exchange information.
At step 102, a request for information is transmitted from a mobile telephone 10, where the request is transmitted through a near field communication (NFC) adapter 52 associated with the mobile telephone 10. The request may be sent automatically by continuously transmitting requests until a response is detected, automatically determining the presence of another NFC-compliant device, and/or manually initiated by a user action.
At step 104, the NFC adapter 53 receives information in response to the request for information from an electronic device, wherein the received information is a NFC signal. The information may include a NFC tag, telephone number, or any other information.
At step 106, a user-sensible query is displayed on the display 14. The query is presented in a user-sensible format on the display of the mobile telephone to an associated user. In response to the query, the user will generally enter user input from the keypad 16. Such user input will generally correspond to a user-friendly designation representing at least one of the electronic device and/or the contact. Such user-friendly designation will typically include, for example, a name, a nickname, acronym, and/or other indicia which the user of the mobile telephone 10 may use to easily refer to the user and/or another NFC-compliant device (e.g. electronic device 62).
For example, if the NFC tag includes the other user and/or device's telephone number, the display may prompt the user of the mobile telephone 10 to save the telephone number to the list of contacts in the electronic phonebook application 80. If the user decides to save the number to the list of contacts in the electronic phonebook application 80, the user will be queried to enter a user-friendly designation (e.g., name, nickname, etc.) for the contact.
In a similar manner, if the NFC tag does not include the user and/or device's telephone number, the display may prompt the user of the mobile telephone 10 to save the identity of the NFC to the electronic phonebook 80 and also provide one or more graphical user screens on the display to enter such information as a user-friendly designation, telephone number and the like.
At step 108, the electronic phonebook stores at least a portion of the received information from another NFC-compliant device 62 in the electronic phonebook application 80. During the storing step, it may preferable for the display 14 to display a message that the information was stored in the electronic phonebook 80.
Preferably, the contact information entered by user (e.g., user input) is used by electronic phonebook 80 to identify the NFC-compliant device in future communications. For example, if the mobile telephone 10 is transferring a song, for example, to a NFC-compliant device already stored in the electronic phonebook application 80, the display 14 will identify the contact name of the individual and/or device prior to and/or during at least a portion of the song transfer.
Another exemplary method 150 in accordance with aspects of the present invention is illustrated in FIG. 8.
At step 152, a request for information is transmitted from a mobile telephone 10, where the request is transmitted through a near field communication (NFC) adapter 52 associated with the mobile telephone 10. The request may be sent automatically by continuously transmitting requests until a response is detected, automatically determining the presence of another NFC-compliant device, and/or manually initiated by a user action.
At step 154, the NFC adapter 53 receives information in response to the request for information from an electronic device 62, wherein the received information is a NFC signal. The information may include a NFC tag, telephone number, or any other information.
At step 156, determining that information associated with the electronic device 62 has previously been stored in the electronic phonebook application 80 of the mobile telephone 10 and a user-friendly designation has been associated with the electronic device 62.
At step 158, providing an indication to the user that the electronic device 62 previously has been communicatively coupled to the mobile telephone 10. The indication may be any suitable indication mechanism. For example, an indication may be a message (e.g., information, query, status, statement, etc.) displayed on the display 14. Such a message may include, for example, “Welcome back ANNA”, assuming the contact name associated with the NFC tag was ANNA, “In Contact with ANNA”, “Do you wish to exchange information with ANNA?”, etc.) and/or an audible indication (e.g. a beep, a tone, a song, etc.). The indication may be provided for a period prior to initiation of a transfer of information, the entire period the mobile telephone 10 is connected to the electronic device associated with the ANNA designation, and/or the indication may be provided for only a portion of the period that the mobile telephone 10 is connected to the electronic device associated with the ANNA designation.
In another embodiment, once it has been determined that the device has been stored in the electronic phonebook and that both NFC-compliant devices (e.g., mobile telephone 10 and electronic device 62) have other communication capabilities (e.g., wireless local area network, Bluetooth, 802.11, WiFi, and/or WiMax capabilities), the NFC-compliant device may utilize one or more other such protocols for facilitating exchanging information. A benefit of using the other communication protocols is that the devices do not have to maintain as close a proximity to each other as required by a near field communication link
