Description

  According to the present invention, in a device having a call function, such as a mobile phone, a video phone, or a television receiver, presence information indicating the state of a user in the vicinity of the device main body can be mutually output with the other party. An object of the present invention is to provide an information processing apparatus that can perform the above processing.

  In recent years, not only voice-based telephones but also videophones with video have appeared. In such a communication device, since the other party's state is not known at all, if it makes a call and responds, it is at home because it is at home, and if the other party does not respond, it is determined that it is away, They were taking measures such as recording on the answering machine.

  However, if the other party's condition can be grasped before making a call, the response can be changed accordingly. For example, if you know that the other party is away before making a call, contact the person by e-mail instead of the call, or if the other party cannot answer or does not want to answer, take a call, etc. Can be taken.

  Information indicating the status of the device or user is called presence information. Presence is a concept that means “state” and “presence”. Presence information specifically refers to the person's profile, location information, schedule, and what kind of equipment (PC, mobile phone, PDA, etc.) Whether it has it, and even the “status” of the schedule and the “current status” of the device are included.

Now, processing in which the videophone device (information processing device) exchanges presence information will be described. FIG. 38 is a sequence diagram showing a presence information transmission / reception process by a conventional information processing apparatus.
Here, when a telephone call or transmission / reception of status information is performed between videophone apparatuses, one of SIP (Session Initiation Protocol), which is a call control protocol used in Internet telephones, is used.

  In a conventional information processing apparatus, when notifying state information that is presence information, a partner to be notified of the state is registered once, and after allowing it, the state information is exchanged. Therefore, as shown in FIG. 38A, when the user A wants the presence information of the user B, the user A uses the information processing apparatus A that the user B uses. A status notification registration request instruction is issued so as to be registered in the device B as a status notification destination. For example, an instruction is given using input operation means such as a remote controller.

  The information processing apparatus A makes a status notification registration request (in SIP, “SUBSCRIBE”) to the information processing apparatus B. The information processing apparatus B presents on the display or the like that there has been a request for status notification registration from the information processing apparatus A, and the user B confirms this and accepts the status notification registration by using the operating means. The information processing apparatus B is instructed to that effect. The information processing apparatus B notifies the information processing apparatus A of acceptance of status notification registration. In this case, in the SIP system, “OK” for “SUBSCRIBE” is notified.

  In the information processing apparatus B, since the state notification registration for the information processing apparatus A is performed, when the state of the user B is changed (for example, going out), the state notification is performed to the information processing apparatus A. In SIP, “NOTIFY” is notified. The information processing apparatus A notified of the status presents the presence information of the user B to the user A. The information processing apparatus A notifies the information processing apparatus B of “OK” for “NOTIFY”.

  FIG. 38B is a sequence diagram when the information processing apparatus B makes a status notification registration request to the information processing apparatus A. The details of this process are the same as in FIG.

  The status notification registration request in this example can be made with a message “Subscribe” if it is SIP. In addition, a message “Notify” can be used for notification of state information that is a notification of a state. Although SIP is assumed as a communication protocol for status notification registration and status notification, other communication protocols may be used. Even when SIP is used, other messages such as “Publish” may be used.

  It should be noted that the status notification registration request may have not only the meaning of notifying the status but also the meaning of requesting registration as a device that permits one-way communication. If the status notification registration permission is returned including not only the meaning of permitting the status notification but also the meaning of permitting the one-way communication, the presence lamp 33 displays the status information to the other party. Thus, one-way communication can be established if the user desires.

  First, it is assumed that the user A wants to see the presence of the user B and instructs the information processing apparatus A to make a status notification registration request. Information processing apparatus A sends a status notification registration request (SUBSCRIBE in the case of SIP) to information processing apparatus B in accordance with the instruction. The information processing apparatus B displays that there has been a status notification registration request from the information processing apparatus A, and after the user B confirms it, gives an instruction to accept the status notification registration request using the operation unit. The information processing apparatus B sends a status notification registration acceptance (OK for SUBSCRIBE) to the information processing apparatus A. The information processing apparatus B stores the information processing apparatus A that returned OK in the state storage table. In this way, the information processing apparatus B sends a status notification (NOTIFY) to the information processing apparatus A that has accepted the status notification registration according to the change in the status. The information processing apparatus A displays presence information based on the status notification. At the same time, OK for NOTIFY is returned to the information processing apparatus B.

  Further, it is assumed that the user B wants to see the presence of the user A and instructs the information processing apparatus B to use the operation unit to make a status notification registration request. The information processing apparatus B sends a status notification registration request (SUBSCRIBE) to the information processing apparatus A according to the instruction. The information processing apparatus A displays that there has been a status notification registration request from the information processing apparatus B, and after the user A confirms it, gives an instruction to accept the status notification registration request using the operation unit. The information processing apparatus A sends a status notification registration acceptance (OK for SUBSCRIBE) to the information processing apparatus B. The information processing apparatus A stores the information processing apparatus B that returns OK in the state storage table. In this way, the information processing apparatus A sends a status notification (NOTIFY) to the information processing apparatus B that has accepted the status notification registration according to the change in the status. The information processing apparatus B displays presence information based on the status notification. At the same time, OK for NOTIFY is returned to the information processing apparatus A.

  In this way, the information processing apparatus provides the state information only to the information processing apparatus that accepts the status notification registration stored in the state storage table.

  However, in this case, in order to obtain the state information, the user must confirm the state notification registration request and the instruction to accept the state notification registration independently of each other, and the operation is complicated. Although it is problematic for any party to accept the status notification unconditionally, even if it is naturally known that the other party is allowed to notify the status in advance, each user gives an instruction by operation. What must be done is poor operability.

  In view of such circumstances, the present invention intends to provide an information processing apparatus that can automatically issue a status notification registration request and an instruction to accept a status notification registration according to the situation.

  First, a conceptual diagram is used to explain the difference between the case where the state notification registration for the other party is performed mutually without using the technique of the present invention and the case where the state notification registration for the other party is performed mutually using the technique of the present invention. To do.

10 and 11 are conceptual diagrams for performing transmission / reception processing of presence information without using the technique of the present invention.
In STEP-11 shown in FIG. 10 (a), Mr. A's TV and Mr. B's TV do not exchange presence information, so there is no information about Mr. B on the presence lamp of Mr. A's TV. It is not displayed and remains unlit, and Mr. A's information is not displayed on the presence lamp of Mr. B's television and remains unlit. Here, it is assumed that Mr. A performs a menu operation on the television. When Mr. A who thought that "I want to see Mr. B's status" is displayed on Mr. A's TV, the option "Do you want to display Mr. B's status on the presence lamp?" Sends a status notification registration request to Mr. B's television. When Mr. B, who thinks "Can I tell you about his condition?" Is displayed on Mr. B's TV, and Mr. B thinks "I will tell you about his condition if Mr. A" operates the remote control, Mr. B The status notification registration acceptance is sent from A's TV to A's TV.

  In STEP-12 shown in FIG. 10B, as a result of the processing of STEP-11, the presence information of Mr. B's television is sent to Mr. A's television. If Mr. B is watching TV, a status notification “TV power ON” is sent from Mr. B's television to Mr. A's television. As a result, the presence lamp of Mr. A's TV shines in a green color indicating that the other party's TV power is ON. As a result, Mr. A can deduce that when he is watching TV, Mr. B is at home. However, since the presence status of Mr. A's television is not sent to Mr. B's television, the presence lamp of Mr. B's television remains off.

  In STEP-13 shown in FIG. 11A, it is assumed that Mr. B performs a menu operation of the television. The option “Do you want to display Mr. A's status on the presence lamp?” Is displayed on Mr. B's TV, and when Mr. B who thinks that “I want to see Mr. A's status” operates the remote control, Mr. B ’s TV Sends a status notification registration request to A's TV. Mr. A's TV says "Can I tell you about his condition?" When Mr. A thinks "I will tell you about his condition if Mr. B" operates the remote, The status notification registration acceptance is sent from Mr. TV to Mr. B's TV.

  In STEP-14 shown in FIG. 11B, as a result of the processing in STEP-13, the presence information of Mr. A's television is sent to Mr. B's television. If Mr. B's TV is turned off, a status notification “TV power OFF” is sent from Mr. A's television to Mr. B's television. As a result, Mr. B's TV presence lamp shines in red indicating that the other party's TV power is OFF. As a result, Mr. B can know that Mr. A is not watching TV. Through these operations, it is possible for Mr. A's television and Mr. B's television to exchange presence information with each other.

FIG. 12 is a conceptual diagram for performing transmission / reception processing of presence information using the technique of the present invention.
In STEP-21 shown in FIG. 12 (a), Mr. A's television and Mr. B's television do not exchange presence information, so there is no information about Mr. B on the presence lamp of Mr. A's television. It is not displayed and remains unlit, and Mr. A's information is not displayed on the presence lamp of Mr. B's television and remains unlit. Here, it is assumed that Mr. A performs a menu operation on the television. When Mr. A thinks "Do you want to display Mr. B's status on the presence lamp?" Sends a status notification registration request to Mr. B's television. Mr. B's TV says "Can I tell you about his condition?" When Mr. B who thought that "I would like to exchange the condition with Mr. A" operated the remote control, Mr. B's TV The status notification registration acceptance is sent from A to the television of Mr. A, and a status notification registration request is sent from the television of B to the television of A. Then, Mr. A's television returns a status notification registration acceptance to Mr. B's television.

In STEP-22 shown in FIG. 12B, as a result of the processing of STEP-21, Mr. A's television and Mr. B's television exchange presence information. If Mr. B is watching TV, the status notification “TV power ON” is sent from Mr. B ’s TV to Mr. A ’s TV, and the other party ’s TV power is ON in the presence lamp of Mr. A ’s TV. Shines in a green color that expresses things. As a result, Mr. A can deduce that when he is watching TV, Mr. B is at home. On the other hand, if Mr. B's TV is turned off, a status notification “TV power off” is sent from Mr. A's television to Mr. B's television, and the presence lamp of Mr. B ’s TV is off when the other party's TV power is off. It glows red to indicate something. As a result, Mr. B can know that Mr. A is not watching TV. Through these operations, it is possible for Mr. A's television and Mr. B's television to exchange presence information with each other. In order to exchange presence information with each other, in the examples of FIGS. 10 and 11, Mr. A and Mr. B required two remote control operations respectively, whereas in the example of FIG. Each needs only one remote control operation.

  If presence information (status information) is notified from the other party before making a call, the user can determine whether to make a call based on the presence information or to use another means. The outline of the process for notifying the status information is described next with reference to FIG. FIG. 13 is a sequence diagram showing a status notification process of the information processing apparatus according to the present invention.

  First, it is assumed that the user A wants to see the presence of the user B and instructs the information processing apparatus A using the remote controller 5 to make a status notification registration request. Information processing apparatus A sends a status notification registration request (SUBSCRIBE in the case of SIP) to information processing apparatus B in accordance with the instruction. The information processing apparatus B displays that there is a status notification registration request from the information processing apparatus A, and after the user B confirms the request, uses the remote controller 5 to give an instruction to accept the status notification registration request. The information processing apparatus B sends a status notification registration acceptance (OK for SUBSCRIBE) to the information processing apparatus A. Up to this point, the conventional information processing apparatus is the same.

  Next, the information processing apparatus B automatically sends a status notification registration request (SUBSCRIBE) to the information processing apparatus A. When there is a status notification registration request from the information processing apparatus B, the information processing apparatus A sends a status notification registration acceptance (OK for SUBSCRIBE) to the information processing apparatus B.

  In this way, since the information processing apparatus A automatically gives the status notification registration to the information processing apparatus B that has been accepted by making the status notification registration request, the user A accepts the registration request one by one. No need to perform operations. In this way, the information processing apparatuses A and B can notify each other of the state information.

  The information processing apparatus B sends a status notification (NOTIFY) to the information processing apparatus A that has accepted the status notification registration in response to a change in the status. The information processing apparatus A displays presence information based on the status notification. At the same time, OK for NOTIFY is returned to the information processing apparatus B.

  On the other hand, the information processing apparatus A sends a status notification (NOTIFY) to the information processing apparatus B that has accepted the status notification registration in response to a change in the status. The information processing apparatus B displays presence information based on the status notification. At the same time, OK for NOTIFY is returned to the information processing apparatus A.

  The overall processing flow is as described above. Next, the processing will be described in detail for each information processing procedure.

FIG. 14 is a flowchart showing the processing of the information processing apparatus A regarding the status notification.
As shown in FIG. 15, a menu for selecting a partner whose presence is to be viewed is displayed on the display unit 11 of the television receiver 2. Here, users B, C, and D (B, C, and D) are targeted for selection. Since user A wants the status information of user B, the cross key 45 and the enter button 44 of the remote controller 5 are used (hereinafter, the selection process on the screen uses the remote controller 5 in this way. ) User B is selected on the screen.

  Alternatively, as shown in FIG. 16 (a), the registration selection menu 112 is displayed during a videophone call with the user B, and the user A confirms the image 111 of the other party and selects whether or not to register. Let Alternatively, as shown in FIG. 16B, the user A is made to input the SIP address 113 of the user B, and the user A is made to select whether or not to register using the registration instruction menu 114. These are all processes corresponding to the user A instructing a status notification registration request to the information processing apparatus B (step S1).

  In accordance with this instruction, the presence processing unit 79 of the information processing apparatus A transmits a status notification registration request to the information processing apparatus B used by the user B (step S2). Here, the presence processing unit 79 of the information processing apparatus A stores a subscription request list in the storage unit 83 shown in FIG.

  FIG. 17 is an explanatory diagram of a subscription request list. The subscription request list is a list indicating a processing state when it is desired to subscribe to the partner's status notification. The items include “SIP address”, “subscription request setting state”, and “state notification registration request processing”.

  The “SIP address” is an address indicating the connection destination of the other party in the IP phone. “Subscription request setting status” indicates whether or not the other party's status notification subscription request is set. “Processing of status notification registration request” indicates the processing status of the status notification registration request for the other party.

The presence processing unit 79 of the information processing apparatus A registers the other party (information processing apparatus B) in the subscription request list in the storage unit 83 as “subscription request not set” and “waiting for response to status notification registration request” (step S3). . When a response to the status notification registration request is received by the presence processing unit 79 from the partner (information processing apparatus B) (step S4), it is confirmed whether the response is status notification registration acceptance (step S5). If the status notification registration is accepted, the partner (information processing apparatus B) is registered as “subscription request already set” in the subscription request list. Further, a user status storage table described later is created for each partner set as “subscription request set” (step S6). If the status notification registration is not accepted, the partner (information processing apparatus B) is registered in the subscription request list as “subscription request not set” and “status notification registration request is not transmitted” (step S7). Thereafter, a mutual registration process for receiving a status notification registration request from the information processing apparatus B is performed (step S8).

FIG. 18 is a flowchart illustrating processing of the information processing apparatus B related to state notification.
When the presence processing unit 79 receives a status notification registration request from the information processing apparatus A (step S11), the information processing apparatus B permits the user B to make a status notification registration request on the screen as shown in FIG. Is displayed and selected (inquires whether the user can accept the status notification registration request) (step S12). Alternatively, as shown in FIG. 20, the presence processing unit 79 has a policy file (a table indicating the processing policy of the SIP address and the status notification registration request), and for a partner whose processing policy is predetermined. Alternatively, permission or disapproval of status notification registration may be selected without inquiring the user (determining whether the status notification registration request can be accepted based on the set policy file). The presence processing unit 79 of the information processing apparatus B confirms whether or not the user B has permitted by the above method (step S13), and if not, rejects the status notification registration request to the other party (information processing apparatus A). Is transmitted (step S14). When user B permits the status notification registration request, as shown in FIG. 21, after registering the address of the partner (information processing apparatus A) in the presence distribution list stored in the storage unit 83 (step S15). The status notification registration request acceptance is transmitted to the other party (information processing apparatus A) (step S16). Next, a mutual registration process for transmitting a status notification registration request to the information processing apparatus A is performed (step S17).

Next, the mutual registration process in step S17 will be described.
FIG. 22 is a flowchart showing the mutual registration process when the status notification registration request is received when the status notification registration request is not transmitted, and the process in step S17 of FIG. 18 is described in detail.
The presence processing unit 79 of the information processing apparatus B confirms whether or not a status notification registration request has been transmitted to the other party (information processing apparatus A) from the other party (information processing apparatus A). When the request is received, it is checked whether or not the partner (information processing apparatus A) is included in the subscription request list in the storage unit 83 (step S21). If it is included in the subscription request list, it is confirmed whether or not the partner is “subscription request set” (step S22), and if it is “subscription request set”, the process is terminated. If “subscription request has not been set”, the process proceeds to step S23.

  If the partner is not included in the subscription request list, the process may proceed to step S24, but before that, a process of temporarily inquiring user B whether or not to send back a status notification registration request to the partner (information processing apparatus A). You may go (step S23). In this case, for example, as shown in FIG. 23, a menu 116 for the user B to select is displayed on the display unit 11 of the television receiver 2 to select whether or not the status notification registration request can be returned. After step S23 or if “subscription request has not been set” at step S22, the presence processing unit 79 of the information processing apparatus B adds the partner to the subscription request list in the storage unit 83 as “subscription request not set” in step S24. "" Wait for response to status notification registration request ".

Then, a status notification registration request is transmitted to the information processing apparatus A that is the partner that received the status notification registration request (step S25), and a response to the status notification registration request is received from the partner (step S26). It is confirmed whether this response is acceptance of the status notification registration request (step S27). If it is “acceptance”, the partner is registered in the subscription request list of the storage unit 83 as “subscription request already set”. Further, a user status storage table described later is created for each partner set as “subscription request set” (step S28).

  If the status notification registration request is not accepted in step S27, the other party is registered in the subscription request list as “subscription request not set” and “a status notification registration request has not been transmitted” (step S29). As will be described in detail later, a status notification registration end process is performed (step S30).

FIG. 24 is a flowchart showing the mutual registration process when the status notification registration request is received from the partner after the status notification registration request is transmitted to the partner, and the process in step S8 of FIG. 14 is described in detail.
When the presence processing unit 79 of the information processing apparatus A receives the state notification registration request after transmitting the state notification registration request to the partner (information processing apparatus B) (step S31), the partner (information processing apparatus B) stores the storage unit. It is confirmed whether or not it is already set in the subscription request list 83 (step S32). If “subscription request has been set”, the partner (information processing apparatus B) is registered in the presence distribution list (step S31), and a status notification registration request acceptance is transmitted to the partner (step S34). If “subscription request has not been set”, the process proceeds to step S35, and a status notification registration request rejection is transmitted to the partner. By this process, it is possible to accept the sent status notification registration request and transmit the status notification including the status information to the information processing apparatus B that has transmitted the status notification registration request.

  FIG. 25 is a sequence diagram when the status notification registration request is rejected by the other party even though the status notification registration request is accepted.

  First, it is assumed that the user A wants to see the presence of the user B and instructs the information processing apparatus A using the remote controller 5 to make a status notification registration request. Information processing apparatus A sends a status notification registration request (SUBSCRIBE in the case of SIP) to information processing apparatus B in accordance with the instruction. The information processing apparatus B displays that there is a status notification registration request from the information processing apparatus A, and after the user B confirms the request, uses the remote controller 5 to give an instruction to accept the status notification registration request. The information processing apparatus B sends a status notification registration acceptance (OK for SUBSCRIBE) to the information processing apparatus A. Up to this point, the conventional information processing apparatus is the same.

  Next, the information processing apparatus B automatically sends a status notification registration request (SUBSCRIBE) to the information processing apparatus A. When there is a status notification registration request from the information processing device B, the information processing device A should send a status notification registration acceptance (OK for SUBSCRIBE) to the information processing device B, but sends a status notification registration rejection. Suppose. In this case, the information processing apparatus B notifies the information processing apparatus A of the end of status notification registration (NOTIFY). The information processing apparatus A sends an OK for NOTIFY to the information processing apparatus B.

FIG. 26 is a flowchart showing the end processing of status notification registration, and details the processing in step S30 in FIG.
The information processing apparatus B confirms whether the partner (information processing apparatus A) is registered in the presence list (step S41), and if registered, transmits the end of status notification registration to the partner (that is, the information processing apparatus). When the rejection is received from A as a response to the status notification registration request, the end of status notification registration is transmitted to the information processing apparatus A) (step S42). If not registered, the process ends.

FIG. 27 is a sequence diagram showing a state information exchange cancellation process when state notifications are registered with each other.
When there is an instruction to cancel the status information exchange from the user A, the information processing apparatus A notifies the information processing apparatus B of NOTIFY that the status notification registration has been completed. The information processing apparatus B notifies the user B and sends an OK for NOTIFY to the information processing apparatus A. The information processing apparatus A further sends a status notification registration release request (UNSUBSCRIBE) to the information processing apparatus B. The information processing apparatus B sends an OK for UNSUBSCRIBE to the information processing apparatus A. This completes the status information exchange.

FIG. 28 is a flowchart showing a state information exchange canceling process. The instruction to cancel the state information exchange may be performed on the information processing apparatus A side or the information processing apparatus B side, but here, the description is made on the assumption that the information processing apparatus A side instructs to cancel the state information exchange. .
User A inputs an instruction to stop status information exchange to information processing apparatus A using remote controller 5 (step S51). For example, as shown in FIG. 29, a menu 117 for selecting a partner whose presence exchange is to be canceled is displayed on the display unit 11 of the television receiver 2, and the user A is made to select it. The information processing apparatus A confirms whether the partner (information processing apparatus B) is registered in the presence distribution list stored in the storage unit 83 (step S52). If registered, the end of status notification registration is transmitted to the partner (information processing apparatus B) (step S53), and the information of the partner (information processing apparatus B) is deleted from the presence distribution list (step S54). This completes the status notification registration termination process.

  Next, status notification registration cancellation processing is performed. It is confirmed whether or not the partner (information processing apparatus B) is included in the subscription request list (step S55). If the partner is not included in the subscription request list, the process ends. If the partner is included in the subscription request list, it is confirmed in the subscription request list whether the partner (information processing apparatus B) has already been set for subscription request (step S56). If it has been set, a status notification registration cancellation request is transmitted to the partner (step S57), and the partner (information processing apparatus B) is “subscription request not set” and “status notification registration request is not transmitted to the subscription request list. "(Step S60).

  In step S56, if the partner is not already set for the subscription request, it is checked whether the partner is "subscription request not set" or "waiting for response to status notification registration request" (step S58). If the other party is “subscription request not set” and “waiting for response to status notification registration request”, the process proceeds to step S60. If the other party is not “subscription request not set” and “waiting for response to status notification registration request”, transmission is performed. Canceled status notification registration (step S59), the process proceeds to step S60.

FIG. 30 is a flowchart showing processing when the end of status notification registration is received from the other party.
When the information processing apparatus B receives the end of status notification registration from the information processing apparatus A (step S61), it reports the end of status notification registration to the user B (step S62). For example, as shown in FIG. 31, that effect is displayed on the display unit 11 of the television receiver 2. The information processing apparatus B registers the partner (information processing apparatus B) in the subscription request list as “subscription request not set” and “state notification registration request not transmitted” (step S63). Subsequently, the information processing apparatus B confirms whether the partner (information processing apparatus A) is registered in the presence distribution list stored in the storage unit 83 (step S64). If registered, the end of status notification registration is transmitted to the partner (information processing apparatus A) (step S65), and the information of the partner (information processing apparatus A) is deleted from the presence distribution list (step S66).

FIG. 32 is a flowchart showing processing when a status notification registration cancellation request is received from the other party.
When the information processing apparatus B receives the status notification registration release request from the partner (information processing apparatus A) (step S71), the information processing apparatus B deletes the information of the partner (information processing apparatus A) from the presence distribution list in the storage unit 83 (step S72). ).

  When mutual registration is performed so that state information can be notified to each other as described above, state information is transmitted and received and a call is made. These processes are described below.

FIG. 33 is a flowchart showing the status notification transmission process.
First, when a presence event notified to the other party occurs (step S81), the presence processing unit 79 detects state information. The presence processing unit 79 sequentially extracts the SIP addresses of the presence distribution destinations from the presence distribution list stored in the storage unit 83 (step S82). The status notification is transmitted to the SIP address extracted from the presence distribution list via the communication unit 72 (step S83). The information processing apparatus confirms whether the status notification has been transmitted to all the distribution destinations in the presence distribution list (step S84). If so, the process ends. If not, the process returns to step S82.

FIG. 34 is a flowchart showing the status notification reception process.
When the information processing apparatus receives the status notification (step S91), the presence information extracted from the status notification is displayed. Alternatively, as shown in FIG. 35, presence information is held in the storage unit 83 in the user state storage table. The user status storage table stores communication availability, television power status, latest operation, time when the latest operation was performed, time when the user's movement was last detected, and the like.

FIG. 36 is a flowchart showing a process for displaying whether or not the user can be called with reference to the presence. A case where the user calls the other party using the call function will be described. Calling is a function that establishes a call that allows voice to be transmitted from the user to the other party. Here, it is assumed that the call is established without the other user's incoming call operation. Establishing a call without the other user's incoming call operation means that even if the call is established and you use the voice to call "Please answer if there is", There may be no users. In order to prevent this, it is possible to make a call only when the presence of a user can be confirmed by referring to the presence of the other party's information processing device or when there is a high possibility that a user is present It is effective to display that it is.
When the user calls the other party, the information processing apparatus checks whether or not the other party's information is included in the user state storage table (step S101). If the other party's information is included in the user state storage table, it is confirmed in the user state storage table whether the other party's TV power state is ON (step S102). If the TV is in an ON state, the display unit 11 displays that a call to the other party and a videophone call are possible. On the other hand, if NO in step S101 or step S102, the process proceeds to step S104, and displays that the other party cannot call but can make a videophone call. Here, the reason why the call cannot be made when the TV power supply state is not ON but the video call is possible is that the process of the video call is included in the case of the video call, and therefore the answering process of the partner information processing apparatus is not performed. This is because it can be estimated that there are no users in the vicinity. Although the television power state is used as presence information here, the presence information is not limited to this and may be other presence information.

  FIG. 37 is a flowchart showing a process for determining whether or not to make a call with reference to presence when the user instructs a call. When the user instructs a call (step S111), the information processing apparatus checks whether the other party is registered as “subscription request set” in the subscription request list and the other party is registered in the presence distribution list. (Step S112). If it is registered as “subscription request set” in the subscription request list and the other party is registered in the presence distribution list, there is a user state storage table corresponding to the other party. Whether the state is ON is confirmed (step S113), and if it is ON, a one-way voice (only transmission) call is established with respect to the other party (step S114). If “NO” in the steps S112 and S113, the process proceeds to a step S116 to display on the display unit 11 that the other party cannot be called. Although the television power state is used as presence information here, the presence information is not limited to this and may be other presence information. If the partner is “subscription request set” in the subscription request list, a status notification including status information is received from the partner. If the partner is registered in the presence distribution list, a status notification including status information is transmitted to the partner. The fact that “subscription request has been set” is registered in the subscription request list and the partner is registered in the presence distribution list means that status information is exchanged with the partner.

  If the status notification is registered as a mutual registration, when a call is received, the callee permits the call without an instruction from the user. This is because it is possible to confirm in advance who the other party is, and it is not necessary to perform confirmation processing again. Note that here, only when a call is received from the other party who has transmitted the status information including the status notification and has received the status information including the status notification, the receiving side receives the call without any instruction from the user. , But you are receiving status information including status notification but not receiving it, or you are receiving status information including status notification but not sending it. The incoming side may also be configured to allow incoming calls for incoming calls from the other party. The fact that the status information including the status notification is transmitted is because the other party is reliable enough to inform the status information, and the fact that the status information including the status notification is received provides the status information. This is because the convenience of automatic incoming call can be provided to the other party instead of receiving the call.
