Here, the name indicated by the data D0 in the presence status confirmation permission list 341 and the presence information indicated by the partner data D2 corresponding to the name are displayed according to the display information indicated by the corresponding data D4. Corresponding to each name (Taro Yamada, Hanako Yamada, Jiro Suzuki) indicated by the data D0, icons schematically showing the shape of the person are displayed, and the display color of the icon is the data D2. It is changed according to the type of presence state indicated by the presence information. In FIG. 9, the presence state indicated by the presence information of the data D2 is indicated by three types of characters “online”, “offline”, and “busy” based on the corresponding data D4. Furthermore, the display color of the corresponding icon is varied depending on the type of presence status. As a result, it is possible to present to the user so that the presence status of the other party can be confirmed at a glance not only by the display characters according to the data D4 but also by the display color of the icon. Here, the type of presence state is shown by using the display color of the icon, but the type may be shown by the shape of the icon.

  With reference to FIG. 10, a processing mode for newly registering a partner to store presence information in the presence state confirmation list 341 will be described. Here, the person whose name is indicated by the data D0 in the presence status confirmation list 341 is a person whose predetermined data is registered in advance in the IP phone number data D1 and IP address data D5 in the telephone directory. Assume that Assume that the corresponding data D3 is set to “No” (registration refusal), “Presence” is set to the data D2, and “Hide” is set to the data D4. A user who desires new registration makes an inquiry of registration acceptance as to whether or not presence information may be registered to the other party registered in the telephone directory via the SIP server 3.

  First, in step S <b> 3, based on the input information from the input unit 29, the control unit 20 has input the name of the other party who wishes to newly register presence information into the presence status confirmation list 341 via the input unit 29. Determine whether or not. If it is determined that there is no such input (NO in step S3), the processing mode for adding the presence status confirmation list ends.

  If it is determined that there is this input (YES in step S3), the control unit 20 searches the presence state confirmation permission list 341 using the information reference unit 35 based on the input name. Based on the search result, the data D1 corresponding to the data D0 matching the input name is read, and the control unit 20 gives a request to add the read data D1 and the presence state confirmation list to the presence information request unit 311. . The presence information request unit 311 generates a packet when the addition request is input, and transmits the generated packet via the communication unit 33 (step S5).

  In this packet, the header portion HD reads and stores the address of the SIP server 3 stored in advance in the second memory 41 as the transmission destination address, and the IP address 411 read from the second memory 41 is the transmission source. Stored as an address. In the data part DB, the ID data 410 and the IP telephone number data 412 read from the second memory 41, the name of the input destination, the command for registration request to the presence status confirmation list 341, and the input from the control part 20 The stored data D1 is stored.

  Here, the name of the other party is entered in step S3, but the other party's IP telephone number may be entered instead. In that case, the control unit 20 retrieves the name indicated by the corresponding data D0 by searching the presence state confirmation permission list 341 using the information reference unit 35 based on the input IP telephone number. It may be.

  Thereafter, a reply packet corresponding to the transmitted registration request is received via the communication unit 33, and the received information is processed by the registration request processing unit 313 (step S7). The registration request processing unit 313 analyzes the data stored in the data part DB of the received packet and determines the response. If it is determined that the analysis result and the response indicate refusal of registration in the presence status confirmation list 341 (“rejected” in step S9), the analysis result is output to the presence information display processing unit 281 via the control unit 20. In step S17, the presence information display processing unit 281 displays “registration refusal” on the display 481 (or display 482). Thereafter, the process returns to step S3.

  If the registration request processing unit 313 determines that the received response is “accepted”, the process proceeds to step S11.

  In step S11, based on the analysis result input from the registration request processing unit 313, the control unit 20 displays the presence status confirmation list 341 via the information update unit 36 in the presence request confirmation partner 341 as indicated by the arrow AR. The value of data D3 is initialized. Here, the data D3 is initialized to “Yes” indicating “acceptance”. Thereby, new registration is completed.

  Thereafter, the process proceeds to step S13, where the presence information display processing unit 281 displays a message “registration complete” on the display 481 (or display 482) based on the analysis result given through the control unit 20, and a series of presences. The status confirmation list addition processing mode ends.

  Returning to step S9, if the registration request processing unit 313 determines that the response indicates information other than “reject” and “accept” (including information on hold) as a result of the analysis (“other (hold)” in step S9). ), The process proceeds to step S15. In step S15, the presence information display processing unit 281 displays the content of the response on the display 481 (or display 482) based on the analysis result given via the control unit 20. Thereafter, the processing mode for adding the presence status confirmation list is terminated.

  In FIG. 10, the process proceeds to the process of inquiring about the next addition request only when the registration acceptance response indicates “reject” in step S <b> 9, but registration is also possible when the response is “accept” and “other (pending)”. After the above process or the display process is completed, the process may return to the process of step S3 to move to a registration request transmission process for the next partner.

  Next, the processing of the SIP server 3 that has received the registration request for the presence status confirmation list described in FIG. 10 from the IP telephone terminal will be described with reference to FIG. First, when the request processing unit 59 of the SIP server 3 receives the registration request packet transmitted from step S5 of FIG. 10 via the network communication unit 51 and the information receiving unit 52 (step S21), the processing is performed at step S23. Migrate to

  The request processing unit 59 outputs the user ID 410 stored in the data part of the received packet to the user authentication unit 54. The user authentication unit 54 searches for the user D / B 55 based on the input user ID 410, determines whether or not a matching user ID is registered, and outputs the determination result to the request processing unit 59. If the request processing unit 59 detects that the user ID of the registration request transmission source is registered in the user D / B 55 based on the input determination result of the user authentication unit 54 (“OK” in step S23), the processing of step S25 Migrate to On the other hand, when it is detected that the user ID of the request transmission source is not registered based on the determination result (“NG” in step S23), the process proceeds to step S37. In step S37, the request processing unit 59 transmits a packet storing the notification of “Invalid User” in the data unit DB to the IP telephone terminal 2 that is the registration request transmission source (step S37).

  In step S25, the request processing unit 59 determines whether the user ID of the request transmission destination is registered in the user D / B 55 based on the determination result by the authentication of the user authentication unit 54. Specifically, based on the name of the other party read from the data part DB of the received packet by the request processing unit 59, the user authentication unit 54 searches for the user D / B and whether the other party name is registered. Detect whether or not. If it is detected that it has been registered (“Yes” in step S25), the process proceeds to step S27. When it is detected that it has not been registered (“No” in step S25), a packet in which the information “Not in database” is stored in the data part DB is generated in the process of step S39, and is sent to the IP telephone terminal 2 that is the registration request transmission source Send to.

  In step S27, the request processing unit 59 generates a registration request packet addressed to the IP telephone terminal 2 of the request transmission destination user, and transmits the packet via the information transmission unit 53 and the network communication unit 51 (step S27). In the header portion of the generated packet, the data D5 of the IP address read from the presence information DB 58 based on the IP phone number data D1 of the other party in the data portion DB of the received packet is stored as the transmission destination address. The address of the SIP server stored in advance in the memory 63 is read and stored as the source address. The data part DB stores the name and IP phone number data D1 of the registration request transmission source user and registration request notification data. This data D1 is read from the data part DB of the received packet and points to the IP telephone number data 412. The name indicates the name read by the search in step S23.

  Thereafter, in step S29, the request processing unit 59 determines whether or not to receive a reply (response) packet from the IP telephone terminal 2 of the registration request transmission destination user for the packet transmitted in step S27 (step S29). ). If the response packet cannot be received (NO in step S29), a packet storing a “No response” notification is generated in step S41 and transmitted to the IP telephone terminal 2 that is the transmission source.

  If the response packet can be received (YES in step S29), the request processing unit 59 generates a response packet in step S31 and transmits it to the IP telephone terminal 2 that is the registration request transmission source. In the data portion DB of the transmission packet, the response contents ('accepted', 'rejected', 'hold') for the registration request read from the data portion DB of the packet received in step S29 are stored.

Thereafter, the request processing unit 59 analyzes the response (response) from the request transmission destination user received in step S29, and determines whether or not it indicates “accept”, that is, permission of the registration request (step S33). If it is determined that “accept” is not indicated, that is, “reject” or “hold” is indicated, a series of processing ends. On the other hand, if it is determined that “accept” is indicated (“permitted” in step S33), the process proceeds to step S35.
In step S35, the request processing unit 59 registers the request transmission source user in the presence state confirmation permission list for the request transmission destination user who has accepted the request transmission source user in the presence state confirmation permission list 341. Permission (acceptance) is transmitted on behalf of the request transmission source user.

  In the data part D / B of the packet transmitted on behalf of this, a command indicating that the registration is accepted on behalf and the transmission of the received request packet read from the data part DB of the request packet received in step S21 The original user's IP telephone number data 412 is stored. At the destination user's IP telephone terminal 2 that has received this proxy transmission packet, the presence state confirmation permission list 341, for example, the data in the presence state confirmation permission list 341 of FIG. The data D2 corresponding to the data D1 that matches the IP telephone number 412 of the department DB is updated to indicate “accept” (Yes) (for example, the data D2 in the data of the arrow AR is updated to “Yes”). )

  FIG. 12 shows a processing procedure in the IP telephone terminal 2 of the registration request transmission destination user synchronized with the processing procedure of FIG. Referring to FIG. 12, in request-destination IP telephone terminal 2, request processing unit 313 receives a registration request packet via communication unit 33 (YES in step S81).

  Then, the request processing unit 313 gives the received packet information to the presence information display processing unit 281 via the control unit 20, so that the presence information display processing unit 281 displays a screen for confirming the registration request based on the input information. The information is displayed on the display 481 (or display 482) (step S83). At this time, the control unit 20 searches the presence status confirmation permission list 341 based on the IP telephone number data 412 pointed to by the input information via the information reference unit 35, and reads the corresponding name data D0. When data D0 is not registered, corresponding data D0 is not read.

  An example of the display screen at this time is shown in FIG. In FIG. 13A, the presence information display processing unit 281 indicates a display example when the name indicated by the corresponding data D0 is read from the presence state confirmation permission list 341 by the control unit 20. (B) indicates a display example when the name indicated by the corresponding data D0 is unregistered and could not be read.

  The user who confirmed the display screen of FIG. 13A or 13B inputs a response to the received registration request by operating the input unit 29. This response indicates one of “accept”, “reject”, and “hold” of the registration request according to the guidance on the display screen (YES in step S85). A packet storing the response is generated by the request receiving unit 313 and transmitted to the SIP server 3 via the communication unit 33.

  When the response of “accept” is transmitted, the request accepting unit 313 receives the packet indicating registration acceptance transmitted from the SIP server 3 in step S35, as described above. Based on the command of the part DB, the data D2 corresponding to the data D1 corresponding to the IP telephone number 412 of the data part DB is “accepted” (Yes) in the presence state confirmation permission list 341 as indicated by the arrow AR in FIG. ) To point to.

  In FIG. 14, one IP telephone terminal 2 (referred to here as the first IP telephone terminal 2) has a desired partner (here, the second IP telephone terminal 2) stored in the presence information D / B 58 of the SIP server 3. A procedure for acquiring and displaying presence information of a user) is shown.

  In the first IP telephone terminal 2, when the presence information display mode is started, the processing after step S51 is performed. Here, the presence information display mode is periodically repeated in the standby mode in which the first IP telephone terminal 2 waits for an incoming call / email, and instead of the predetermined standby screen displayed in the standby mode, or in the standby mode. Presence information is displayed superimposed on the screen. Alternatively, the execution is started each time it is detected that the switching operation from the folded state to the open state is performed based on the detection signal from the open / close detection sensor 47 in the standby mode. By switching to the open state, a standby screen is displayed on the main display 481 in conjunction with the operation, but presence information is displayed instead of the standby screen or superimposed on the standby screen.

  First, in step S51, basic setting processing for starting a mode is performed. For example, acquisition of a destination for which presence information is to be acquired, determination of timing for transmitting a request, display of a predetermined standby screen, and the like. The standby screen data is read from the second memory 41 by the CPU 40 and displayed on the main display 481 via the image generation circuit 432.

  A packet storing the information acquisition request is generated by the presence information request unit 311 in step S53 and transmitted to the SIP server 3 via the communication unit 33. The data part DB of this packet includes the data of the IP telephone number of the second IP telephone terminal 2 of the other party from whom the presence information is to be acquired, which is input in advance through the input unit 29, together with the information acquisition request command.

  Thereafter, the presence information request unit 311 receives a response packet from the SIP server 3 (step S55). The data part DB of the received packet includes data on the IP telephone number of the second IP telephone terminal 2 and presence information.

  The presence information receiving unit 312 analyzes the information stored in the data part DB of the received packet, and determines whether or not the presence information of the user of the second IP telephone terminal 2 has been acquired (step S57). If the presence information cannot be acquired because it indicates predetermined dummy data (NO in step S57), the process returns to step S53 and the request is retransmitted. On the other hand, if it can be obtained (YES in step S57), the process proceeds to step S59.

  In step S59, the acquired presence information is given to the presence information display processing unit 281. The presence information display processing unit 281 outputs an image based on the input presence information to the image generation circuit 432, and thus the main display 481. The presence information is displayed superimposed on the original standby screen. Specifically, the presence information receiving unit 312 generates display data D4 based on the acquired presence information. Then, the data D4 corresponding to the data D1 that matches the IP telephone number data of the second IP telephone terminal 2 read from the received packet in the presence state confirmation permission list 341 via the information update unit 36 is generated by the generated data D4. Update. Presence information is displayed based on the updated data D4. At this time, the control unit 20 updates the corresponding presence information D2 using the presence information read from the received packet.

  An example of presence information displayed in a superimposed manner on the standby screen in step S59 is as shown in FIG. FIG. 9 shows a case where the data D3 corresponding to the three users indicates “accept” (Yes) when the request for acquiring the presence information of the three users is transmitted. The presence information display processing unit 281 searches the presence state confirmation permission list 341 via the control unit 20 and the information reference unit 35 based on the data of the IP telephone number of the second IP telephone terminal 2 of the packet received in step 55. When it is detected that the corresponding data D3 indicates “reject” (No), the received presence information is not displayed, but when it is detected that the data D3 does not indicate “reject” (No), The data D4 and D0 are read out and applied to the image generation circuit 432. As a result, the information of FIG. 9 is displayed on the display 481 (or display 482) by the image generation circuit 432.

  Here, the start of the presence information display mode is synchronized with the switching operation from the folded state to the open state, which is one of the operations for displaying the standby screen, but the operation to be synchronized is not limited to this. For example, when the IP telephone terminal 2 performs a sliding operation between the casings, the presence or absence of a sliding state may be detected by a mechanical contact type so that a switch incorporated in the sliding mechanism is activated. Moreover, even if it is not a mechanical contact type, the detection by the combination of the Hall element using the optical element by a photo interrupter and a small magnet is applicable. When a standby screen is displayed without detecting a slide operation (non-sliding state), presence information as shown in FIG. 9 may be displayed superimposed on the standby screen.

  When the SIP server 3 receives the information acquisition request packet transmitted in step S53 of the first IP telephone terminal 2 (YES in step S61), it confirms the requested presence information (step S63). Specifically, when the request processing unit 59 inputs a presence information acquisition request packet via the network communication unit 51 and the information receiving unit 52, the request processing unit 59 responds via the information reference unit 56 to the data portion DB of the input packet. The presence information D / B 58 is searched based on the IP phone number data of the second IP phone terminal 2 read out from. As a result of the search, the data D1 matching the IP telephone number of the second IP telephone terminal 2 is searched, and the presence information indicated by the data D2 corresponding to the searched data D1 is read from the presence information D / B 58.

  The request processing unit 59 generates a packet storing the read presence information in the data unit DB, and transmits the generated packet to the first IP telephone terminal 2 that is the transmission source (step S65).

  Next, update of the presence information D2 of the presence information D / B 58 of the SIP server 3 will be described with reference to FIG. Here, the communication procedure for the second IP telephone terminal 2 to update its own presence information D2 registered in the presence information D / B 58 is shown. Each of the IP telephone terminals 2 shown in FIG. Then, processing for sequentially updating the own presence information D2 registered in the presence information DB 58 is performed.

  Specifically, in the second IP telephone terminal 2, in step S 71, the presence information notification unit 32 reads out its own presence information 342 stored in the information storage unit 34 via the information reference unit 35, A packet in which presence information 342 and an information update request are stored in the data part DB is generated and transmitted to the SIP server 3 via the communication part 33. The IP address 411 read from the second memory 41 is set as the transmission source address of the header portion HD of this packet. This information update request transmission process is repeated at intervals of several millimeters.

  In the SIP server 3, in step S <b> 73, the request processing unit 59 receives the information update request packet via the network communication unit 51 and the information receiving unit 52. Then, the request processing unit 59 searches the presence information D / B 58 based on the transmission source address of the header part HD of the received packet, and the data D2 corresponding to the matching IP telephone number data D1 is stored in the data part DB. The presence information 342 is updated through the information update unit 57 (step S75). Thereby, the presence information D / B 58 can be updated to indicate the latest presence state of the second IP telephone terminal 2.

  In the process of S73 in FIG. 14, the authentication process of the user authenticating unit 54 is omitted, but the authentication process of the user authenticating unit 54 is performed so that the presence information D / B 58 is inadvertently updated. It may not be performed.

  When the own IP telephone terminal 2 periodically transmits the presence information 342 to the SIP server 3, the presence information of other communication partners is acquired from the SIP server 3 and displayed simultaneously with the transmission, and the presence information is also displayed. The status confirmation permission list 341 may be updated with the received presence information. In this case, the presence information being displayed can be updated in real time, and the contents of the presence status confirmation permission list 341 can be updated to indicate the latest presence status in real time.

  As described above, according to the present embodiment, real-time presence of a specific registered partner in conjunction with simple operations such as opening / closing switching operation / sliding operation of the casing of IP telephone terminal 2 for confirming the screen The state can be automatically displayed on a specific screen such as a standby screen of the IP telephone terminal 2. As a result, it is possible to know the current presence status of the registered partner by referring to the screen of the IP telephone terminal 2 with a simple operation for confirming the screen, and to switch the communication function according to the presence status of the partner. Therefore, smooth information transmission is possible.

  The communication function may be switched according to the presence status of the other party as follows. That is, the presence status confirmation permission list 341 is displayed on the main display 481, and by selecting and specifying a partner to be contacted from the displayed list, the presence status indicated by the partner data D2 is obtained. Accordingly, it is possible to provide a shortcut to the optimal contact function.

  Unlike the general address book where the partner information can be freely registered, the presence status confirmation permission list 341 can be registered only after accepting the “acceptance” of the registered partner for security reasons, as described in step S21. After the registration is accepted, as described in step S35, confirmation of the presence status of the user is permitted from the other party as well.

  Here, the type of presence information D2 is not limited to the rough type described with reference to FIG. 4, but may be a detailed classification such as during work, during rest, and during capture. In addition, in step S51, the registered partner whose presence information is to be automatically displayed may be set for all members of the presence status confirmation list 341. Alternatively, one or a plurality of persons may be selectively specified in advance, or may be classified into a specific group and displayed for each group.

  Regarding the display, the following features may be provided. In other words, the display screen of the registered partner's presence information is a standby screen when switching from the folded state to the open state, but it is superimposed on the standby screen displayed according to the dedicated shortcut key operation, etc. It may be displayed. In addition, the presence of the other party registered on the displayed standby screen is displayed in response to an operation to return to the standby mode in which the standby screen is displayed from the power saving mode in which the brightness of the LCD screen is reduced and the display screen is deleted. Information may be superimposed and displayed.

  When a data item (name or the like) on the presence information display screen in FIG. 9 is selected by operating the input unit 29, an application to be activated by the presence information D2 corresponding to the selected item may be switched. For example, when the partner presence information D2 indicates “offline” or “loading”, the control unit 20 activates the mail creation function and displays the mail creation screen. When instructing “online”, the telephone call function is activated and a telephone call screen is displayed. In this way, even if the other party is busy, you may want to convey urgent requirements or leave an answering message, so shortcuts for unique functions such as making calls and creating mail regardless of the other party's presence status It is also possible to activate the key and switch to the function.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
