In FIG. 13, the own communication terminal uses only the video conference service and is not linked to other services, and the presence of each communication terminal in the destination list is “meeting”, “offline”, “online”, etc. Information is only displayed.

  FIG. 14 shows a case where the own terminal device uses a video conference service and a text chat service, and both services cooperate with each other, and a communicable service based on the integrated presence is displayed in addition to the normal presence. That is, the mobile terminal with the communication ID “02ab” indicates that the text chat service can be used, the mobile terminal with the communication ID “02ac” indicates that the video conference service and the text chat service can be used, and the communication ID “10ac” "" Indicates that the video conference service can be used.

  Next, with reference to FIG. 15, details of a process in which the user operates the mobile terminal 20aa to display a destination list that is a list of destination terminal candidates with the mobile terminal 20aa will be described. FIG. 15 is a sequence diagram of an example from login to display of the destination list of the mobile terminal according to the present embodiment.

A user (user) performs a login operation via the input device 202 of the mobile terminal 20 (step S1801). Then, the operation input reception unit 12 of mobile terminal 20 accepts the log-in operation, transmits the login request information to the text chat management system 50 ₂ (step S1802). This login request information includes a communication ID and a password for identifying the mobile terminal 20aa that is the own terminal as the request source. Note that the communication ID and password are input from the user via the operation input receiving unit 12 during the login operation. Incidentally, when the login request information from the portable terminal 20aa to the text chat conference management system 50 ₂ is transmitted, text chat management system 50 ₂ is a receiving side, to grasp the IP address of the mobile terminal 20aa is a transmission side it can.

Next, the authentication unit 52 of the text chat management system 50 ₂ performs an authentication process receives the login request information through the transmitting and receiving unit 51 (step S1803). This authentication process will be described with reference to FIG. 12 similar to the authentication process of the video conference dedicated terminal 10ab. FIG. 12 is a flowchart illustrating an example of the authentication process according to the present embodiment.

First, the authentication unit 52 of text chat management system 50 _2, for the set of the communication ID and the password included in the login request information, the set of common information management apparatus 60 the same communication ID and password to the authentication management DB6002 Management It is determined whether it has been performed (step S1501). This determines whether the text chat management system 50 ₂ acquires the authentication management table from the authentication management DB6002 common information managing device 60, the same communication ID and password pair is managed. Incidentally, it is determined whether or not the common information managing apparatus of the same communication ID and a password in 60 pairs are managed, the authentication unit 52 of the text chat management system 50 ₂ may acquire the determination result. If it is determined that the same communication ID and password pair as the communication ID and password pair included in the login request information is included in the authentication management DB 6002, the process advances to step S1506 to indicate successful login. Generate authentication result. If the same communication ID and password combination as the communication ID and password included in the login request information is not included in the authentication management DB 6002, the process proceeds to step S1507, and an authentication result indicating a login failure is displayed. Generate.

Thus, text chat management system 50 ₂ receives the login request information from the portable terminal 20aa, based on the communication ID and the password included in the login request information, generates an authentication result indicating a successful login.

Returning to the description of FIG. Transceiver 51 of the text chat management system 50 ₂ transmits the authentication result generated in the authentication process of step S1803 to the mobile terminal 20aa (step S1804). Text chat management system 50 _2, the description will be continued as the ones that sent the authentication result indicating a successful login to the mobile terminal 20aa. The mobile terminal 20aa, when receiving authentication information indicating a login failure from text chat management system 50 ₂ to display a screen indicating that the login has failed to the display device 203 of the portable terminal 20aa, the processing is terminated.

Then, the transceiver unit 11 of the portable terminal 20aa receives the authorization result indicating successful login from text chat management system 50 _2, the requesting destination list request, and notifies the presence of the mobile terminal 20aa (step S1805). The presence of the mobile terminal 20aa to be notified here is “online (online, communicable)”, “text chatting (chat)”, “offline (offline, communicable)” or the like.

Then, state management unit 53 of the text chat management system 50 _2, the presence status information management DB6005 definitive request source terminal of the common information managing device 60 (a portable terminal 20aa) to "Online (communicable)" (step S1806) .

Text chat management system 50 ₂ status notification, acquisition and transfer unit 55 obtains the presence of such common information of the management device 60 status management DB6005 from the terminal 20ab (communication ID "02ab") (step S1811).

The transmitting and receiving unit 51 of the text chat management system 50 _2, to the requesting terminal (portable terminal 20aa), and transmits the information of the destination list of the request source terminal (such as a communication ID and presence of terminal candidate) (Step S1812). Here, the information of the destination list of the mobile terminal 20aa that is the request source terminal and the presence of the mobile terminal 20ab that is a candidate of the destination terminal included in the destination list are transmitted to the mobile terminal 20aa.

The destination list generator 17 of the mobile terminal 20aa includes information of the destination list from text chat management system 50 _2, receives the presence of terminal candidate, creating a destination list on the display unit 203 (step S1813 ).

<< Processing example of status information processing section >>
The status notification / acquisition / transfer unit 55 of the transmission management system 50 provided for each service transfers the presence information (status information) received from the transmission terminals 10 and 20 to the common information management device 60 and also manages the common information management. Using the presence information provided from the device 60, the presence of the destination list displayed on the transmission terminals 10 and 20 is displayed / updated.

  The status information processing unit 63 is configured so that the transmission management system 50 provided for each service displays and updates the destination list of the transmission terminals 10 and 20 and the timing when the transmission terminal 10 and 20 notifies the presence information change. The latest presence information is generated and provided to the transmission management system 50 of each service.

  FIG. 16 is a flowchart showing an example of processing of the status information processing unit 63 of the common information management device 60. The user information transferred from the status notification / acquisition / transfer unit 55 of the transmission management system 50 provided for each service. The process from reception of presence information to transmission of integrated presence information to the transmission management system 50 of each service is shown.

  In FIG. 16, the state information processing unit 63 updates the presence information table (FIG. 10A) based on the received presence information of the service (step S11).

  Next, the state information processing unit 63 acquires the presence information of each service associated with the corresponding user (user ID) from the presence information table (FIG. 10A) (step S12).

  Next, the state information processing unit 63 determines whether or not a response availability (status) has been acquired for the presence information (text chat service and video conference service in the example of FIG. 10) of all the services to be linked (step S13).

  When response availability (status) is not acquired for the presence information of all services (NO in step S13), the state information processing unit 63 applies the corresponding information from the presence / status correspondence table (FIGS. 10B and 10C). Whether or not the service n of the presence information of the user can be handled is acquired (step S14), and n is incremented to return to the determination of all acquisition (step S13).

  When response availability (status) is acquired for the presence information of all services (YES in step S13), the state information processing unit 63 combines the response availability (status) of all services from the integrated rule table (FIG. 10D). The integrated presence information (common status) is acquired (step S15).

  Next, the state information processing unit 63 updates the presence information table (FIG. 10A) based on the acquired integrated presence information (common status), and transmits it to each service (step S16).

Figure 17 is a sequence diagram showing an example of processing when there is update of presence information from the client, it is assumed that there is a text chat service by video conferencing service and text chat management system 50 ₂ by videoconference management system 50 _1, Transmission terminals (communication terminals) are shown as clients A to C. Note that the client A corresponds to a terminal whose user ID (communication ID) is “01ab” in FIG.

17, when the client A notifies that it has been modified in the presence of, for example, "chat" the text chat management system 50 ₂ (step S101), text chat management system 50 ₂ is the client A, the destination registration client B is notified that the presence of client A has been changed to “chat” (step S102).

Also, text chat management system 50 _2, the state notification, acquisition and transfer unit 55, to the common information managing device 60, the presence of the client A notifies that it has been changed to "chat" (transfer) (step S103).

  The state information processing unit 63 of the common information management device 60 updates the presence information table (FIG. 10A) of the state information management DB 6005 for the presence of the text chat service of client A being changed to “chat”. (Steps S104 and S105) (corresponding to Step S11 in FIG. 16).

  Next, the state information processing unit 63 acquires the presence of all services for the client A from the presence information table (FIG. 10A) of the state information management DB 6005 (steps S106 and S107) (corresponding to step S12 of FIG. 16). ). Here, it is assumed that “chat” is acquired for the text chat service and “meeting” is acquired for the video conference service.

  Next, the state information processing unit 63 determines whether or not the response (status) corresponding to the presence “chat” of the text chat service and the presence “meeting” of the video conference service is made, based on the presence / status correspondence table of the state information management DB 6005 (FIG. 10 ( b) Obtained from (c)) (steps S108 and S109) (corresponding to steps S13 and S14 in FIG. 16). Here, “unavailable” is acquired for the text chat service and “unavailable” is acquired for the video conference service.

  Next, the state information processing unit 63 obtains the integrated presence (common status) corresponding to the status “unavailable” of the text chat service and the status “unavailable” of the video conference service, and the integrated rule table (see FIG. )) (Steps S110 and S111) (corresponding to step S15 in FIG. 16). Here, the integrated presence “unavailable” is acquired.

Next, the state information processing unit 63 updates the presence information table (FIG. 10A) of the state information management DB 6005 for the change of the integrated presence of the client A to “unavailable” (steps S112 and S113). video conferencing management system 50 ₁ notifies the integrated presence "unavailable" client a (step S114) (corresponding to step S16 in FIG. 16).

In response to this, the video conference management system 50 _1, client B, and notifies the integration of client A Presence "unavailable" to C (step S115, S116).

<< Other processing example of status information processing section >>
The processes in FIGS. 16 and 17 described above are based on the presence information table shown in FIG. 10A, and are based on the assumption that a common user ID (communication ID) exists for a plurality of services. However, in practice, different accounts (user identification information) may be used in each service, and in this case, the service cannot be applied as it is. Therefore, here, a description will be given of a case where different accounts are used in each service.

  FIG. 18 is a diagram showing examples of various tables held in the state information management DB 6005. The presence information table, the presence / status correspondence table, and the integration rule table are the same as in FIG. 10, but the presence information table is changed. The presence / status correspondence table and the integration rule table are the same as those in FIG.

  18A, the presence information table includes items of “ID”, “Chat Account”, “Chat Presence”, “Conference Account”, and “Conference Presence”. Have. “ID” is management-specific identification information. “Chat Account” is an account of the user in the text chat service. “Conference Account” is an account of the user in the video conference service. If more services are linked, the service account and status are added. Here, the chat account and the conference account can be regarded as communication IDs.

  FIG. 19 is a flowchart showing another processing example of the status information processing unit 63 of the common information management device 60, which has been transferred from the status notification / acquisition / transfer unit 55 of the transmission management system 50 provided for each service. The process from when the presence information of the user is received until the integrated presence information is transmitted to the transmission management system 50 provided for each service is shown.

  In FIG. 19, the state information processing unit 63 updates the presence information table (FIG. 18A) based on the received presence information of the service, and acquires the corresponding ID from the user identification information (account) (step S21). ).

  Next, the state information processing unit 63 acquires presence information of each service linked from the presence information table (FIG. 18A) based on the acquired ID (step S22).

  Next, the state information processing unit 63 determines whether or not response availability (status) has been acquired for the presence information (text chat service and video conference service in the example of FIG. 18) of all the services to be linked (step S23).

  When response availability (status) is not acquired for the presence information of all services (NO in step S23), the state information processing unit 63 applies the corresponding information from the presence / status correspondence table (FIGS. 18B and 18C). Whether or not the service n of the presence information of the user can be supported (status) is acquired (step S24), and n is incremented to return to the determination of all acquisition (step S23).

  When response availability (status) is acquired for the presence information of all services (YES in step S23), the state information processing unit 63 combines the response availability (status) of all services from the integrated rule table (FIG. 18D). Integrated presence information (common status) is acquired by (step S25).

  Next, the state information processing unit 63 updates the presence information table (FIG. 18A) based on the acquired integrated presence information (common status), and transmits it to each service (step S26). When updating the presence information table, user identification information (account) of another service to be notified is acquired and designated when transmitting to each service.

Figure 20 is a sequence diagram showing an example of processing when there is update of presence information from the client, it is assumed that there is a text chat service by video conferencing service and text chat management system 50 ₂ by videoconference management system 50 _1, Transmission terminals (communication terminals) are shown as clients A to C. Note that the client A corresponds to a terminal whose user ID (communication ID) is “01ab” in FIG.

In Figure 20, the client A notifies with an account "a@example.com" in text chat service that has been changed in the presence of, for example, "chat" the text chat management system 50 ₂ (step S201), the text Chat Administration system 50 ₂ to the client B, which is the client a and the destination register, the presence of the client a's account "a@example.com" notifies that it has been changed to "chat" (step S202).

Also, text chat management system 50 _2, the state notification, acquisition and transfer unit 55, to the common information managing device 60, the presence of the client A's account "a@example.com" was changed to "chat" This is notified (transferred) (step S203).

  The state information processing unit 63 of the common information management device 60 is notified that the presence of the text chat service of the client A of the account “a@example.com” has been changed to “chat” (the presence information table ( FIG. 18A is updated, and ID “1” corresponding to the account “a@example.com” is acquired (steps S204 and S205) (corresponding to step S21 in FIG. 19).

  Next, the state information processing unit 63 acquires the presence of all services for the client A with ID “1” from the presence information table (FIG. 18A) of the state information management DB 6005 (steps S206 and S207) (FIG. 19). Corresponding to step S22). Here, it is assumed that “chat” is acquired for the text chat service and “meeting” is acquired for the video conference service.

  Next, the status information processing unit 63 determines whether the response corresponding to the presence “chat” of the text chat service and the presence “meeting” of the video conference service is made, according to the presence / status correspondence table of the status information management DB 6005 (FIG. 18 ( b) (c)) (steps S208 and S209) (corresponding to steps S23 and S24 in FIG. 19). Here, “unavailable” is acquired for the text chat service and “unavailable” is acquired for the video conference service.

  Next, the state information processing unit 63 obtains the integrated presence (common status) corresponding to the status “unavailable” of the text chat service and the status “unavailable” of the video conference service, using the integrated rule table of the state information management DB 6005 (FIG. 18D). )) (Steps S210 and S211) (corresponding to step S25 in FIG. 19). Here, the integrated presence “unavailable” is acquired.

Next, the state information processing unit 63 updates the presence information table (FIG. 18A) in the state information management DB 6005 for the change of the integrated presence of the client A with ID “1” to “unavailable” and updates the television. and an account "0001" in the conference service (step S212, S213), and notifies the integrated presence "unavailable" client a's account "0001" to the video conference management system 50 ₁ (step S214) (step S26 in FIG. 19 Corresponding).

In response to this, the video conference management system 50 _1, client B, and notifies the integration of client A Presence "unavailable" to C (step S215, S216).

  In addition, although the cooperation between the video conference service and the text chat service has been described, various other services using the presence information, such as a video chat service, an instant messaging service via SNS, a call service, other text chat services, etc. Needless to say, it can be linked with.

<< Further processing example of status information processing section >>
In the processing examples shown in FIGS. 10 and 16 to 20 described above, for all terminals displayed in the destination list, presences in a plurality of services linked in a system are acquired, and communication is possible as integrated presence. Was displayed. However, among other terminals displayed in the destination list displayed on a certain terminal (target terminal), there may be services that are not registered as destinations with the target terminal. Displaying presence even for various services is problematic in terms of security and privacy. In general, in this type of service, it is assumed that the destination can be registered only when mutual approval is obtained, and the presence is shared between terminals that register with each other. Beyond that, presence will be provided. Therefore, in this processing example, the integrated presence to be provided is limited based on the destination information for each service.

  The data held in the status information management DB 6005 is the same as that shown in FIG. 10 or FIG. In addition, there is an integrated destination list as data that is temporarily generated and used in the course of processing. FIG. 21 is a diagram illustrating an example of the integrated destination list. FIG. 21A corresponds to the case of FIG. 10 in which a common communication ID exists in the service, and FIG. This corresponds to FIG. 18 where there is no common communication ID.

In FIG. 21 (a), the integration destination list, the text chat management system 50 ₂ and each of the destination list management DB5003 teleconference management system 50 _1, based on the communication ID of the terminal to be provided on consolidated presence information acquisition The destination information (communication ID) is merged. In the example shown in the figure, the communication ID “01aa” is the terminal for which the integrated presence information is provided, and the communication IDs “01ab”, “02ab”, and “10ac” are registered in both the text chat service and the video conference service. However, the communication ID “02ac” indicates that the destination is registered only in the video conference service.

In FIG. 21 (b), the integration destination list, the text chat management system 50 ₂ and each of the destination list management DB5003 teleconference management system 50 _1, based on the communication ID of the terminal to be provided on consolidated presence information acquisition The destination information (chat account, conference account) is merged based on ID (identification information) that associates accounts of both services for each terminal. In the example shown in the figure, the terminal corresponding to the chat accounts “b@example.com”, “c@example.com”, “e@example.com” is assumed to have the ID “1” as a terminal for providing integrated presence information. Although the destination is registered in both the text chat service and the video conference service, the terminal corresponding to the conference account “0004” indicates that the destination is registered only in the video conference service.

  FIG. 22 is a flowchart showing a processing example of the status information processing unit 63 of the common information management device 60. The user information transferred from the status notification / acquisition / transfer unit 55 of the transmission management system 50 provided for each service is shown in FIG. The process from reception of presence information to transmission of integrated presence information to the transmission management system 50 of each service is shown. Note that a case where a common communication ID exists for a service will be described using the integrated destination list of FIG. 21A. However, even when a common communication ID does not exist for a service, an account for each service is once shared. It can be applied in the same way by converting to the ID.

  In FIG. 22, the state information processing unit 63 receives an update notification of presence information in the text chat service from the client A (communication ID “01ab”) via the transmission / reception unit 61 (step S31).

  The state information processing unit 63 reflects the received presence information of the text chat service in the presence information table (FIG. 10) of the state information management DB 6005 (step S32).

  The state information processing unit 63 updates the common status (integrated presence information) in the presence information table of the state information management DB 6005 based on the updated presence information (step S33).

  The status information processing unit 63 determines whether or not the destination information has been acquired from the transmission management system 50 of all services used by the client A (step S34). Here, all the services used by the client A indicate services in which presence for the client A exists in the presence information table. When a common communication ID does not exist in the service, it indicates a service in which the account of the client A exists.

  When the state information processing unit 63 determines that the destination information has not been acquired from the transmission management system 50 of all services used by the client A (No in step S34), the status information processing unit 63 transmits the client A from the transmission management system 50 of that service. Destination information is acquired (step S35).

  The status information processing unit 63 inquires the acquired destination information for all services of each client in the presence information table, and if there is no contradiction in existence, the integrated information list of all services of the client A is maintained while maintaining the correspondence with the services. (FIG. 21) is added (step S36), and the process returns to the determination of acquisition of destination information (step S34).

  When the state information processing unit 63 determines that the destination information has been acquired from the transmission management system 50 of all services used by the client A (Yes in step S34), the presence information table for all communication IDs in the integrated destination list. It is determined whether or not the common status (integrated presence information) has been transmitted (step S37).

  If the status information processing unit 63 determines that there is an untransmitted client (No in step S37), the integrated information limited to the service used by the destination partner in the integrated destination list in the integrated presence information of the client A Presence information is generated (step S38).

  The state information processing unit 63 transmits the generated integrated presence information to each service of the client in the integrated destination list (step S39), and returns to the determination of transmission of the integrated presence information (step S37). If the state information processing unit 63 determines that the information has been transmitted to all clients (Yes in step S37), the state information processing unit 63 ends the processing.

Figure 23 is a sequence diagram showing an example of processing when there is update of presence information from the client, it is assumed that there is a text chat service by video conferencing service and text chat management system 50 ₂ by videoconference management system 50 _1, Transmission terminals (communication terminals) are shown as clients A to C.

23, when the client A notifies that it has been modified in the presence of, for example, "online" in the text chat management system 50 ₂ (step S301), text chat management system 50 ₂ is the client A and the destination registration client B is notified that the presence of client A has been changed to “online” (step S302).

Text chat management system 50 _2, the state notification, acquisition and transfer unit 55, to the common information managing device 60, the presence of the client A notifies that it has been changed to "online" (transfer) (step S303) .

The case where it selects is assumed.

  FIG. 24 is a sequence diagram illustrating an example of a process for starting connection between a plurality of terminals according to the present embodiment.

First, when the user selects a destination terminal having the communication ID “01ab” in the destination list 4100 from the input device 202 of the mobile terminal 20aa, the operation input receiving unit 12 receives a request to start connection (step S2102). The transmission / reception unit 11 of the mobile terminal 20aa includes the communication ID “02aa” of the request source terminal (mobile terminal 20aa) and the communication ID “01ab” of the destination terminal (video conference dedicated terminal 10ab), and starts connection. sending a start request information indicating a desire to text chat management system 50 ₂ (step S2102). As a result, to know the IP address "1.4.1.1" of the text chat management system 50 ₂ requesting terminal (mobile terminal 20aa). Here, text chat management system 50 _2, the presence of the request source terminal and the destination terminal are managed by the status management DB6005 common information managing device 60 may be updated, for example, "online (during a call)." .

  In step S2101, when a destination terminal with a communication ID “02aa” is selected from the destination list 4100 of the mobile terminal 20aa, for example, any service (video conference or text chat) is used to connect to this destination terminal. Moreover, you may select together. In step S2102, the start request information may include a service name of a service used between the request source terminal and the destination terminal.

In the case of using the TV conference dedicated terminal 10 as a request source terminal, transmitting and receiving unit 11 of the television conference dedicated terminal 10 transmits a start request information of step S2102 to the television conference management system 50 _1. Thus, the request source terminal transmits start request information to the transmission management system 50 that manages its own call control.

Next, the session management section 56 of the text chat management system 50 ₂ generates a session ID (step S2103). Here, it is assumed that “se1” is generated as the session ID. The generated session ID “se1”, the communication ID “02aa” of the request source terminal (mobile terminal 20aa), and the communication ID “01ab” of the destination terminal (video conference dedicated terminal 10ab) are associated with the session management DB 5002. Are stored and managed (step S2104). Furthermore, the session management section 56 of the text chat management system 50 _2, out from the relay apparatus management DB5001 operating state of the relay device 30 of the "online", the request source terminal (portable terminal 20aa) and the destination terminal (teleconference dedicated terminal 10ab ) To determine the appropriate relay device 30 for communication (here, it is assumed that the relay device 30a is determined), and the session management DB 5002 uses this relay device 30a and the session ID “se1” generated in step S2103. Are stored and managed in association with each other (step S2105). In the above, the method for determining the relay device 30 is, for example, when the request source terminal (mobile terminal 20aa) and the destination terminal (video conference dedicated terminal 10ab) communicate with each other on the network having the widest communication band. A method of selecting the device 30 can be considered.

For example, when the request source terminal and the destination terminal perform only the text chat service, the content data transmitted and received between the request source terminal and the destination terminal is text data. Accordingly, in the above step S2105, without selecting the relay device 30, it may be established directly session between the requesting terminal and the destination terminal, or to establish a session through the text chat management system 50 ₂ Also good.

The transmitting and receiving unit 51 of the text chat management system 50 _2, step a session ID "se1" generated at S2103, IP address "1.2.1.2" of the relay device 30a determined in step S2105 and the requester The data is transmitted to the terminal (mobile terminal 20aa) and the destination terminal (video conference dedicated terminal 10ab) (steps S2106 and S2107). The transmitting and receiving unit 51 of the text chat management system 50 ₂ transmits the IP address of the request source terminal IP address and the destination terminal (the portable terminal 20aa) (teleconference dedicated terminal 10 ab) to the relay device 30a (Step S2108) . The IP address of the relay device 30a can be acquired from the relay device management DB 5001 via the storage / read processing unit 58. Accordingly, a session is established between the request source terminal (mobile terminal 20aa) and the destination terminal (video conference dedicated terminal 10ab) (step S2109).

  Thereafter, content data is transmitted and received between the request source terminal (mobile terminal 20aa) and the destination terminal (video conference dedicated terminal 10ab) using the session established in step S2109 via the relay device 30a. The

  Although the description has been made on the assumption that a common communication ID is used for the text chat service and the video conference service (for example, the case shown in FIG. 10), the communication ID is not common for the text chat service and the video conference service ( For example, even in the case shown in FIG. 18, communication can be started by clicking the icon in the “communication enabled service” column of the destination list. In this case, the common information management device 60 is inquired about the correspondence between the communication ID of the text chat service and the communication ID of the video conference service, the communication ID of the service corresponding to the destination terminal is acquired, and a start request is issued using the communication ID. It can be realized by doing.
