Description

  The present invention relates to a communication terminal capable of easily transmitting additional information unique to a user using a display name of presence information prepared by a presence system.

  Conventionally, IP networks that communicate with TCP / UDP and IP such as the Internet and Intranet display hypertext and provide many services such as streaming, mail, and bulletin boards. However, all of these requests the accumulated data from the client and are provided by the server, and lack bidirectionality and real-time properties. In terms of real-time, services such as chat, VoIP, and video conferencing have been realized, but these can all be used online (ie, while connected to the network) and are still fully real-time two-way communications. It cannot be said. It is because it accesses without knowing the other party's situation at all and is influenced by chance.

  Therefore, in the future, in the IP network, it will be necessary to grasp the real-time situation of the other party and to perform communication capable of interactive communication at a higher level. That is, it is necessary to fully grasp presence information. Such presence information is defined by RFC3856, RFC2778, particularly RFC2778 issued by IETF (Internet Engineering Task Force), and is already being serviced by some terminals.

  First, the presence information will be described. Typical presence information notified by terminals that can currently use this service includes four types of information “Online”, “Offline”, “Away”, and “Not Available”. There is information indicating the status. For example, when the connection status of the partner terminal changes from “Offline” to “Online”, the presence agent unit (Presence Agent, hereinafter referred to as PA unit) of the partner terminal automatically notifies the message to that effect, and the watcher unit ( (Subscriber) receives this, extracts the presence information of this state change, stores information “Online” in the partner presence information section, and displays it on the display of the terminal. In the present specification, a system for notifying and exchanging presence information as described above is called a presence system.

  However, in order to make future two-way communication easy to use in real time, more specific additional information such as “meeting”, “during a business trip”, “lunch break”, “chuo”, “ Additional information indicating the current state of the user such as “no intention to talk” is indispensable. In the existing presence system, since the type (contents) of presence information that can be set by the system is determined, there is no mechanism for notifying such additional information, and the situation of the other party may not be fully recognized before communication. Very many.

  In the future, messenger-type wireless communication terminals equipped with two-way communication and presence functions are expected to become widely used, and the demand for communication after grasping the other party's current situation will increase, and additional information will be exchanged. This is expected to become important.

Hereinafter, a conventional peer-to-peer presence system that provides the above-described presence information will be described. FIG. 8A is an explanatory diagram for notifying conventional presence information in one direction, and FIG. 8B is an explanatory diagram for notifying conventional presence information in both directions. Although a peer-to-peer description is given, it can also be used with a presence server. In FIG. 8 (a), 100 is a transmitting terminal A, 101 is a presence user agent section (Presence User Agent, hereinafter referred to as PUA section) that provides presence information to the presence system, and 102 is a self-presence storing own presence information. An information unit 103 is a presence agent unit (PA unit) that can generate a notification in response to processing of a subscription request and a change in presence status. Here, SIP (Session Initiation Protocol) will be described as a protocol, but any protocol that can exchange presence information using IP packets may be used.

  Reference numeral 200 denotes a network such as an IP network, and reference numeral 300 denotes a presence information receiving terminal B. A watcher unit 304 monitors presence information from the PA unit of the terminal A100, and a partner presence information unit 305 stores presence information on the notified partner. In the case of bidirectional notification, 104 shown in FIG. 8B is a watcher unit of the transmitting terminal, 105 is a partner presence information unit of the transmitting terminal, 301 is a PUA unit of the receiving terminal, and 302 is a receiving terminal. The self-presence information section 303 is a PA section of the receiving terminal.

First, a case will be described in which presence information is requested from the terminal B300 to the other terminal A100, and the terminal A100 notifies it. FIG. 9 is an explanatory diagram in the case where notification is made when the conventional presence information is requested. In FIG. 9, the PUA unit 101 of the terminal A 100 sets presence information in the self-presence information unit 102. In this state, when the terminal B300 transmits a “SUBSCRIBE” message indicating that it is desired to subscribe to the presence information of the other party for a certain period (sequence 1), the PA unit 103 that has received the message “200” in the case of subscription OK.
“OK” is transmitted (sequence 2), and a “NOTIFY” message for notifying presence information is transmitted from terminal A100 (sequence 3). On the other hand, if the notification is OK, “200 OK” is transmitted from terminal B300 to terminal A100 (sequence 4). The watcher unit 304 of the terminal B300 updates the information in the partner presence information unit 305 with the received presence information of the terminal A100.

Next, when the presence information is changed and this event is detected, the terminal A100 may notify the terminal B300. FIG. 10 is an explanatory diagram for detecting and notifying a change in conventional presence information. As shown in FIG. 10, when it is detected that the state of the terminal A100 is changed, the PUA unit 101 of the terminal A100 changes the presence information (sequence 1). At this time, the presence information of the terminal A100 is changed from “Online” to “Away”, for example. When the PA unit 103 detects this (sequence 2), it transmits a “NOTIFY” message notifying the presence information to the terminal B300 (sequence 3). Upon receiving this, the watcher unit 304 of the terminal B300 sends “200” to the terminal A100.
“OK” is transmitted (sequence 4). Thereafter, the watcher unit 304 updates the information of the partner presence information unit 304 based on the received presence information of the terminal A100 (sequence 5). As a result, the presence status of the terminal A100 in the partner presence information unit 305 is changed from “Online” to “Away”. Note that the sequences 4 and 5 depend on mounting and may be in the reverse order.

As described above, the current presence system can only notify representative presence information such as “Online”, “Offline”, “Away”, “Not Available”, and the like. Therefore, a user who spontaneously notifies additional information unique to the user by a convenient method has appeared. In other words, after the user's name (or handle name), for example, “Taro”, additional information such as recent status, for example, “at home”, or the item of interest, for example, “Under test” is added. The user who notifies as additional information (original presence information) appeared (see Non-Patent Document 1). As a delimiter indicating that additional information is added, for example, “(at mark)” is used, and is used in a notation method such as “name (at mark) additional information”.

  Therefore, how the additional information unique to the user is transmitted and received will be described. FIG. 11 is an explanatory diagram in the case of notifying conventional additional information unique to the user, and FIG. 12 is a block diagram of the presence rule setting function of the conventional communication terminal. As shown in FIG. 11, when additional information unique to the user is added to the display name of the terminal A100 and changed from “Taro” to “Taro (at mark) at home”, the presence information connection state “Online” Although there is no change, the PUA unit 101 changes the display name of the self-presence information unit 102 (sequence 1). When the PA unit 103 detects this (sequence 2), it transmits a “NOTIFY” message notifying the presence information to the terminal B300 (sequence 3). When the watcher unit 304 of the terminal B300 receives this, it transmits “200 OK” to the terminal A100 (sequence 4). Thereafter, the watcher unit 304 updates the information in the partner presence information unit 305 based on the received presence information of the terminal A100 (sequence 5). Thereby, the display name of “Taro” in the partner presence information section 305 is changed to “Taro (at mark) at home”, and the screen display of the terminal B300 is also changed to “Taro (at mark) at home”. can do. Note that the sequences 4 and 5 depend on mounting and may be in the reverse order. As a result, the user of the terminal B300 knows that the user “Taro” of the terminal A100 is at home, and can perform communication with content suitable for “at home”.

  As shown in FIG. 12, the presence status of the communication terminal is changed by setting a presence rule in advance. In FIG. 12, 106 is a presence rule setting means for setting presence rules, and 107 is a presence rule registration unit. The presence rule setting means 106 sets, in the presence rule registration unit 107, the “Away” time of each user to “5 minutes”, and the “Not Available” long time to “30 minutes”. It is. The presence rule registration unit 107 registers the presence rule set in this way.

108 is presence information setting means for setting its own presence information, 109 is a display name setting means for setting a display name at this time, and 110 is also the presence status of its own terminal, for example, “Online” and “Offline”, which are operated for a certain period of time. If there is not, state setting means 111 for determining and setting “Away”, “Not Available” or the like, and 111 is a presence information notifying means provided in the PA unit 103 for notifying presence information. The presence status determined by the status setting means 110 according to the presence rule for the input display name is stored in the self-presence information unit 102. This presence information is notified to the watcher unit of the other party by the presence information notification means 111.
YAHOO! “Computer terminology“ atmark ”, [online], August 8, 2005, Internet <URL: HYPERLINK“ http://computers.yahoo.co.jp/dict/peripheral/keyboard/key/ 2920.html "http://computers.yahoo.co.jp/dict/peripheral/keyboard/key/2920.html>

  As described above, the presence information notified on the system by the conventional PA units includes only information such as “Online”, “Offline”, “Away”, “Not Available”, and some of the users are unique to the user. Additional information devised in the above, ie, your name (display name), for example, “Taro” followed by a delimiter “(at sign)”, for example, “home” additional information, your name (display) Instead of (name), information of (name + original additional information) is displayed and notified as “at home at Taro”.

  However, in the wireless communication terminal, the size of the keyboard and each key itself is small, and 12 numeric keys for inputting numbers are combined with several function keys to be used as keys for inputting characters and symbols. There was a problem that the operability was bad. If the user does not change the presence information due to poor operability, accurate presence information cannot be transmitted and the meaning of referring to the presence information is lost.

  However, complicating the system with both terminals and infrastructure will destroy the simple and flexible communication culture that many users have created. Moreover, it cannot be considered that such a complex system can respond flexibly to changes in the situation like a human being. If possible, it is expected to improve the operability while maintaining the configuration of the conventional presence system.

  Furthermore, in a wireless LAN, the location may be automatically specified depending on the area. For example, in a wireless LAN provided in a company or school, if an access point is provided in an area such as a conference room, a laboratory, a break room, a cafeteria, or a parking lot or a bicycle parking lot, the location and for what purpose You can estimate if you are there. For example, if you are in a conference room, laboratory, break room, or cafeteria area, when combined with the time information, you can determine with high probability that you are in a meeting, experimenting, resting, or eating. If so, it can be determined that the user is returning home (working) or moving.

  Accordingly, an object of the present invention is to provide a communication terminal and an electric device that can easily transmit additional information unique to a user to a communication partner in addition to presence information.

FIG. 4 is an explanatory diagram of a display screen sample, FIG. 4 is a block diagram of the presence function of the wireless communication terminal according to the first embodiment of the present invention, and FIG. 5A is an explanatory diagram of a message of the wireless communication terminal according to the first embodiment of the present invention. FIG. 5B is a diagram for explaining the structure of the communication packet of the message shown in FIG. 6A, and FIG. 6 is a flowchart for easily notifying additional information according to the first embodiment of the present invention.

  In FIG. 1, 1 is an IP network such as the Internet, and 1a is a wireless LAN connected to the IP network for communication. Reference numerals 2a and 2b denote access points, and reference numerals 3a, 3b and 3c denote wireless communication terminals such as WiFi (registered trademark) phones which perform communication based on a protocol defined by IEEE802.11a / g. The wireless communication terminals 3a, 3b, and 3c have a display such as an LCD (liquid crystal), and the display screen displays their own presence information and presence information of contact list members as shown in FIG. An input button is displayed by a GUI for enjoying services such as VoIP, mail, Web connection, presence information notification, and the like.

  Further, 4 is a presence server for performing communication conforming to a protocol such as SIP. The presence server 4 is not necessary when performing peer-to-peer communication as in the first embodiment. In the first embodiment, wireless communication will be described. However, as long as it is a communication terminal and presence system having a presence function, it may be wired or the like, and is not limited thereto. In the following, SIP will be mainly described as a protocol. However, the protocol is not limited to SIP such as RVP (Microsoft) as long as it is a protocol for notifying presence information including a display name.

  For example, a plurality of access points 2a are provided in a company or the like to construct a wireless LAN 1a having a plurality of areas, and wireless communication terminals 3a and 3b existing in each area can be connected wirelessly. The access point 2b is connected to the IP network 1 and can be connected wirelessly to the wireless communication terminal 3c at home. Here, the ESS-ID of the access point 2a of the wireless LAN is “XYZ-111” as an example, and can be changed for each area. The local IP address of the wireless communication terminal 3a is “10.1.1.1” as an example, and the IP address of the wireless communication terminal 3c is “192.168.0.10” as an example.

Next, the configuration of the wireless communication terminal according to the first embodiment will be described. In FIG. 2, 11 is a transmission / reception unit, 12 is a communication control unit, and 13 is a data processing unit that compresses / decompresses signals and encodes / combines them. The transmission / reception unit 11 includes a frequency conversion unit and a modulation / demodulation unit (not shown). The receiving unit of the frequency converting unit converts the signal received by the antenna into an intermediate frequency signal (IF signal) by mixing it with an oscillation signal having a predetermined frequency. The transmission unit of the frequency conversion unit performs frequency conversion by mixing a modulated wave supplied from a modulation / demodulation unit, which will be described later, with an oscillation signal having a predetermined frequency, and transmits the result from the antenna. The receiving unit of the modem unit demodulates the IF signal output from the frequency converting unit and sends it to the communication control unit 12. Further, the transmission unit of the modem unit modulates the data supplied from the communication control unit 12 and sends it to the frequency conversion unit of the transmission / reception unit 11.

  Next, the communication control unit 12 performs frame synchronization and frame format processing. The reception side of the communication control unit 12 extracts data for one frame from the reception data supplied from the modulation / demodulation unit of the transmission / reception unit 11 at a predetermined timing, and after releasing the scramble, etc. 16, and the control unit 16 sends multimedia data such as an VoIP audio signal and MPEG image signal of the RTP payload to the data processing unit 13 by the communication means 20 described later. In addition, the transmission side of the communication control unit 12 scrambles the data supplied from the data processing unit 13 with the communication control unit 12 to the data that is added to the header by the communication unit 20 and converted into an IP packet. Each frame is sent to the modulation / demodulation unit of the transmission / reception unit 11 at a predetermined timing.

Output from (described later). On the transmission side of the data processing unit 13, an analog audio signal input from the microphone 15 or a video signal from a camera or the like (not shown) is converted into a data signal by A / D conversion, encoded and compressed, and the data signal Is sent to the communication means 20 and sent to the communication control unit 12 as an IP packet.

  Next, 16 is a control unit, 17 is a storage unit, 17a is a self-presence information unit that records its own presence information provided in the storage unit 17, and 17b is a partner presence information unit that also records the presence information of the other party. is there. Reference numeral 17c denotes a presence rule registration unit that sets under what conditions “Online”, “Offline”, “Away”, and “Not Available” are set as presence information. For example, “Away” is logged in to the presence system, but “Away” is set when the user of the terminal does not take action within a predetermined time. For example, “5 minutes” is set as a predetermined time. Similarly, “Not Available” is also logged in to the presence system, but is set to “Not Available” when the user of the terminal does not act for a very long time, for example, “30 minutes” is set as a certain time It is. In addition, “Away” and “Not Available” itself can be set or not, and other options can be set. The difference between “Not Available” and “Away” is the difference in the length of time, whether it is time to leave the seat or whether it is appropriate to be absent.

  An additional information unit 17d stores additional information as user-specific presence information. Additional information, for example, “going out” is the display name of the user, eg “Taro” followed by delimiters “(at mark)”, “%”, “|”, etc. And is notified to the other party as a display name with additional information. As the delimiter, in addition to “(at mark)”, “%”, “|”, etc., any symbol or character information that can identify additional information and a display name can be used. Additional information registered in the additional information unit 17d is set by the additional information setting unit 29 described later. In the communication terminal according to the first embodiment, the user opens the pull-down menu A of the “presence / addition” button shown in FIG. 3, selects “additional information registration”, opens a setting screen (window), and inputs. Once such a registration process is performed by the user, the screen display of the pull-down menu B is automatically generated and displayed by the display screen generating means 31 described later.

Therefore, the additional information can be determined by referring to the pull-down menu B and selecting any additional information corresponding to the pull-down menu B. If there is no corresponding additional information, the additional information setting means 29 may newly register it. Since it can be input using a pull-down menu, it can be input with a single touch, making input extremely easy. Note that most of the additional information stored in the additional information unit 17d is additional information registered by the user, but it is preferable to store information indicating that there is no additional information separately in advance, for example. . This will be described later.

  Reference numeral 17e denotes a schedule part for entering a user's schedule, and reference numeral 17f denotes a display order storage part. When the “schedule import” button shown in the lower part of FIG. 3 is pressed, the schedule entered in the schedule part 17e is set as additional information. This will be described in detail in Example 2.

  Further, the display order storage unit 17f only needs to be “at home” as in “Taro (at mark) at home”, but it may be “at home” and “mealing”. ”And private, for example, a plurality of additional information in which“ abdominal pain ”and“ fever ”are mixed, are written in a certain order and in a certain format. In such a case, “Taro (at mark) staying at home (at mark) eating” is performed according to the input order. When adding a plurality of additional information, a button for confirming the selected information is provided in addition to a menu for selecting the additional information. In addition, for example, “(at mark)” and “&” are used separately, as in “Taro (at mark) at work & abdominal pain & fever”, and “(at mark)” and “&” are added to each additional information. It is also possible to give a difference to the contents, and set “(at mark)” as the priority display group in the display order in which the priority contents are displayed first, and “&” as the other subordinate display group. For this reason, the menu for selecting additional information is displayed so that “(at mark)” and “&” can be input, or additional information added to “(at mark)” and “&” is displayed in two groups. You can do it. The display order storage unit 17f is where the rules for such a notation order are set. It may be a rule that the input order is in principle priority order. Note that only the additional information with the highest priority may be added when a plurality of states are set by using the priority order stored in the display order storage unit 17f.

  Subsequently, 18 is a key input unit for inputting using a keyboard, 18a is a graphical user interface (hereinafter referred to as GUI) unit as a function realizing means for performing display control so that it can be input from a screen using a pointing device, A display unit 19 drives an LCD (liquid crystal) display or the like. The key input unit 18 receives an input from a numeric keypad, a function key, or the like for inputting the telephone number of the other party and passes it to the control unit 16. The GUI unit 18a selects a region that can be input using a pointing device and inputs corresponding contents.

  By the way, the control unit 16 is composed of many function realizing means, and is configured as a function realizing means for reading out the control program stored in the storage unit 17 to the main memory of the central processing unit (CPU) and realizing each function. Is. In any case, each function is executed by software using a CPU and a control program as hardware.

  Reference numeral 20 denotes a communication means as a function realization means for performing communication using protocols such as SIP, RTP, TCP / UDP, and IP. 21 is a presence user agent (PUA) unit as a function realization means for providing presence information to the presence system, and 22 is a presence agent (PA) as a function realization means capable of generating a notification in response to processing of a subscription request or presence status change. ) Part 23 is a watcher part as a function realizing means for acquiring presence information as a client. The watcher unit 23 has a function of requesting presence information by transmitting a “SUBSCRIBE” message and receiving presence information by receiving a “NOTIFY” message.

  Now, the PUA unit 21 and the PA unit 22 are provided with means for executing the following specific functions.

  First, the PUA unit 21 will be described. The PUA unit 21 is provided with the following configuration. Reference numeral 24 denotes presence rule setting means for setting presence rules. The presence rule setting means 24 sets the presence rule of each user in the presence rule registration unit 17c, for example, sets the time until it becomes “Away”, or sets the time until it changes to “Not Available”. Is. In the communication terminal of the first embodiment, the pull-down menu A of the “presence / addition” button shown in FIG. 3 is opened, “Presence rule setting” is selected, and the setting screen is opened and set.

  Further, 25 is presence information setting means for setting its own presence information, 26 is display name setting means for setting a display name at this time, and 27 is state setting means for setting the presence status. When the user determines additional information, the display name setting means 26 is notified of this additional information by the additional information determining means 30, and a delimiter is placed after the user's own display name set in advance, and this additional information is added. Display name with additional information. If there is no additional information, the display name is used as it is. Presence information setting means 25 stores these in self-presence information section 17a.

  The display name (name) can be appropriately set by the user, but the presence information is managed by the ID. Therefore, when the display name is not set by the user, the display name setting means 26 displays the ID as the display name. . When both the ID and the display name are set, the display name setting unit 26 displays the set display name as it is as the display name. As an example, “123456” shown in <Not Available> in FIG. 3 is a case where the other user has not set a display name, and the other party's ID is displayed as it is.

  Then, the user opens the pull-down menu C and can input “Online”, “Offline”, “Away”, “Not Available” for the terminal, and the state setting means 27 registers the presence rule based on the system state. Referring to the section 17c, it is determined whether the state is “Online”, “Offline”, “Away”, “Not Available” or the like according to the presence rule, and one state is selected. The presence information setting means 25 sets this in the self-presence information unit 17a.

  Subsequently, 29 is additional information setting means for setting user-specific additional information, and 30 is additional information determination means for determining additional information to be notified. Reference numeral 31 denotes display screen generation means. When the additional information is registered by the user, the display screen generating means 31 automatically generates a screen display of the presence information and displays it on the display when the pull-down menu B is opened unless deleted. Note that the deletion process is performed by additional information deletion means (not shown). Clicking “Delete additional information” in the pull-down menu A opens a list of additional information and deletes it.

  In the first embodiment, the registered additional information is displayed in a list as a pull-down menu B for selecting additional information as shown in FIG. 3, and the user selects one from the menu. From this, the additional information determining means 30 determines the selected one as additional information. As described above, a plurality of selections can be made. When information indicating that there is no additional information is stored in the additional information section 17d, when the user selects this information, the presence information is directly notified to other communication terminals without adding the additional information. Whether or not to add additional information can be freely selected by the user. It is also preferable to provide link information for new registration linked to a setting screen for registering additional information.

  The “presence / addition” pull-down menu A in FIG. 3 includes “presence rule setting” in which, in addition to setting or deleting additional information, a setting screen (window) is opened and presence rules are set in the presence rule registration unit 17c. ", Or link information such as" display name setting "for opening a setting screen (window) for setting its own display name in the self-presence information section 17a is provided. In addition, the pull-down menu A includes “login” for logging in to the presence system and “logout” for logging out from the presence system. When logging in, enter your ID on the login screen. Furthermore, “rename setting” is provided for performing a renaming process without displaying the display name of the partner as it is when notification of presence information is received from the partner. At this time, the renaming process for the partner display name is performed and registered in the partner presence information unit 17b. The “director” shown in <Away> in FIG. 3 is obtained by renaming the display name of the other party on the receiving side and renaming it as the “director” without displaying the display name of the other party as it is.

  Subsequently, the PA unit 22 is provided with the following configuration. 22a is presence information notification means. When presence information is requested from another communication terminal or when presence information is transmitted, the presence information notification means 22a takes out its own presence information from the self-presence information section 17a and transmits it to the watcher section 23 of the other party. .

  The configuration of the wireless communication terminal according to the first embodiment has been described above. Hereinafter, the operation of the wireless communication terminal according to the function book diagram of FIG. 4, the configuration example of the packets of FIGS. 5A and 5B, and the flowchart of FIG. Explain. In FIG. 4, the user can open a “presence rule setting” from the pull-down menu A of FIG. 3 and input a presence rule. Thus, the presence rule is set in the presence rule registration unit 17c. Similarly, when “additional information registration” in the pull-down menu A is opened and additional information is input, the additional information setting unit 29 registers the additional information unique to the user in the additional information section 17d. It is also possible to delete it.

  With respect to the display name, the user can open the pull-down menu B for selecting additional information shown in FIG. 3 and easily select additional information. At this time, the additional information determining means 30 sends it to the display name setting means 26. Notice. Furthermore, the user can open the “display name setting” in the pull-down menu A and input a display name, and these are stored in the self-presence information section 17a.

  Regarding the presence state, the state setting unit 27 refers to the rule set in the presence rule registration unit 17c and compares the system state at that time to automatically determine which state, and the presence information setting unit 25 displays the status. It is stored in the self-presence information section 17a together with the name.

  Thereafter, when an incoming “SUBSCRIBE” message for requesting presence information or an event for providing presence information occurs, the presence information notification means 22a refers to the self-presence information section 17a and displays the messages shown in FIGS. 5 (a) and 5 (b). Is sent to the watcher part of the other terminal. FIG. 5B shows a packet structure of a “NOTIFY” message for notifying presence information from the wireless communication terminal 3c of FIG. 1 to the wireless communication terminal 3a. FIG. 5A shows the SIP header and SIP body (text). is there. In FIG. 5B, the entire message is encapsulated as a payload and transmitted.

The notification of presence information is described according to PIDF (presence information data format) in a protocol such as SIP, but in the first embodiment, a new SIP body (text) described in XML (see FIG. 5A) is extended. A tag <custom: nickname> is provided and a display name can be written here. FIG. 5A shows a case where the display name “at home” with additional information generated by the display name setting means 26 is displayed as the display name. In this way, if the protocol notifies the presence information including the display name, a display name with additional information combining “display name” and “additional information” can be displayed, and the additional information can be notified to the partner terminal. .

  The communication sequence of presence information in the first embodiment is the same as that described in the related art. When a “SUBSCRIBE” message indicating that the presence information of the other party is desired to be subscribed for a certain period is transmitted from the wireless communication terminal 3b, the wireless communication terminal 3a that has received this message transmits “200 OK” when notifying the subscription OK, A “NOTIFY” message for notifying presence information is transmitted from the wireless communication terminal 3a. On the other hand, if the notification is OK, "200 OK" is transmitted from the wireless communication terminal 3b to the wireless communication terminal 3a. The wireless communication terminal 3b updates the received presence information of the wireless communication terminal 3a.

  Further, when an event for notification occurs, it may be detected and notified from the wireless communication terminal 3a to the wireless communication terminal 3b. When the presence state of the wireless communication terminal 3a changes, the PUA unit 21 of the wireless communication terminal 3a changes the presence information. When the PA unit 22 detects this, it transmits a “NOTIFY” message to the wireless communication terminal 3b, and upon receiving this, the watcher unit 23 of the wireless communication terminal 3b transmits “200 OK” to the wireless communication terminal 3a. . Thereafter, the watcher unit 23 updates the presence information corresponding to the wireless communication terminal 3a in the wireless communication terminal 3b.

  Next, a method of transmitting presence information with additional information according to the first embodiment will be described based on the flowchart of FIG. As shown in FIG. 6, an additional information selection menu such as a pull-down menu is displayed (step 1), and the process waits for additional information displayed in the menu to be selected (step 2). Next, it is determined whether or not the additional information selected in step 2 is other than the information indicating that there is no additional information (step 3). Although not described in detail, in addition to the information that there is no additional information at step 3, it is also possible to determine link information for new registration. If the link information is newly registered, the process does not proceed to step 7, but a setting screen for registering additional information is opened and newly registered, and the process returns to step 2.

  If information indicating that there is no additional information in step 3 is selected, the process proceeds to step 7. If another additional information is selected in step 3, it is confirmed whether or not there is additional information (step 4). If there is another additional information in step 4, return to step 2 and repeat this. If there is no other additional information in step 4, the additional information determination means 30 determines additional information for generating a display name with additional information (step 5).

  Next, the display name setting means 26 adds the determined additional information to the display name to generate a display name with additional information (step 6), and the presence information setting means 25 stores this in the self-presence information section 17a (step 8). ). When information indicating that there is no additional information is selected in step 3, the display name setting means 26 determines the display name as it is (step 7), proceeds to step 8, and stores it in the self-presence information section 17a.

  Next, at this time, it is checked whether or not the subscription request for presence information from another terminal has expired (step 9). When there is a request, unique presence information with additional information is notified to this terminal ( Step 10), the process ends. If there is no request at step 9, the process is terminated.

As described above, the communication terminal according to the first embodiment can select the additional information setting unit that can easily set the unique additional information in advance while maintaining the currently used presence function, and the predetermined additional information. Since additional information determining means and presence information notifying means for transmitting this as a display name with additional information are provided, additional information unique to the user can be easily transmitted. In conventional communication terminals, the system side determines the type (contents) of presence information and cannot notify its own additional information and cannot fully recognize the other party's situation before communication. It is possible to communicate after grasping in advance. In addition, although Example 1 is a wireless communication terminal, the same effect can be obtained by a communication terminal connected by wire.

(Example 2)
Embodiment 2 of the present invention relates to a communication terminal and a presence information transmission method that can automatically transmit unique additional information in addition to presence information. FIG. 7 is a configuration diagram of a wireless communication terminal according to the second embodiment of the present invention. The communication terminal according to the second embodiment and the communication terminal according to the first embodiment have basically the same configuration, and the same reference numerals indicate the same configuration.

  In FIG. 7, 17g is a correspondence table in which an ESS-ID, a BSS-ID, an IP address or an IP address prefix (a few digits before) is associated with the access point 2a, 2b, the installation location of the router, and related information. This is communication information extraction means for extracting communication information from a wireless communication packet conforming to a protocol defined by IEEE802.11a / g as shown in FIGS. 5 (a) and 5 (b). The communication information may be an ESS-ID or BSS-ID of the access points 2a, 2b, etc., an IP address of a router (not shown), or a prefix thereof. As an example of using a prefix, there is a case where country information where the router exists is displayed. In addition, what is necessary is just to utilize the communication information which shows a position as communication information, when GPS is mounted. When the communication information extracting unit 32 extracts these pieces of communication information, the additional information setting unit 29 refers to a correspondence table 17g described later, and converts the information into the installation locations and related information of the access points 2a and 2b and the router. As this related information, there is, for example, “during a meeting” which is presumed to be used when the installation location is a conference room. The additional information determination means 30 determines the converted location information and related information as additional information.

  In addition to this, it is also possible to perform additional location information from the schedule. That is, the schedule of the user is carefully written in the schedule part 17e, and the probability that the action according to this schedule is performed is high. Therefore, the additional information setting unit 29 refers to the time of the time measuring unit (not shown) and the schedule unit 17e, and the schedule schedule is used as it is, or the schedule is converted into location information to obtain additional information. It is very effective to confirm. For example, if a schedule is scheduled from 1 pm to 3 pm in the schedule section 17e, pressing the schedule capture (see FIG. 3) button at 2 pm will result in “meeting” as additional information and “Taro” (At sign) Conference "is notified to the other party as a display name with additional information. Thus, although the schedule is additional information, it becomes additional information different from the additional information stored in the additional information section 17d.

  It is also possible to distinguish the delimiters by displaying “(at mark)” for items scheduled in the schedule section 17e and “&” for others, and displaying them as schedule priority. At this time, “Taro (At Mark) Conference & Contact with Mr. A & Preparation of Materials” etc.

  In addition, by providing various modes, various information under this mode can be automatically set as additional information simply by inputting this mode in advance. For example, if “drive mode” indicating that the vehicle is to be moved is designated, “drive in progress” and “moving in progress” can be notified as additional information thereafter, and the location information and related information described above can also be provided. In addition, it is possible to display a time difference according to the overseas location by specifying the mode, and to provide information for correcting the time of the terminal with the standard time.

Reference numeral 33 denotes an RSSI detection unit that measures a received signal strength indicator (hereinafter referred to as RSSI) of radio waves. The detection unit of the RSSI detection unit 33 is provided in the transmission / reception unit 11. The communication information extraction means 32 compares the RSSI value measured by the RSSI detector 33 with the level value, adopts the communication information obtained when the communication status is good when a high RSSI value is shown, and the RSSI value is If it is low, it means that it will be out of the communication range, so the obtained communication information is not adopted. In this way, by determining whether or not to adopt communication information according to the strength of the RSSI value, it is possible to change one's presence information before moving to a non-communication area, thereby preventing notification of erroneous presence information. it can. In the wireless LAN 1a of a plurality of areas provided with a plurality of access points, the position where the RSSI value is larger is set as the location in the area where the areas overlap. A value other than the RSSI value such as a frame error rate may be used as a criterion for determining the communication status.

  As described above, the communication terminal according to the second embodiment can automatically transmit additional information unique to the user. The conventional communication terminal cannot sufficiently recognize the other party's situation before communication, but can communicate after grasping the other party's state in advance by additional information. It can also provide useful information automatically.
