Description

  The present invention relates to a communication status output device and a program.

  A technique for switching (dynamically) switching sessions of a plurality of terminals held by a user is known (for example, see Patent Document 1). The technique described in Patent Document 1 is to install a session management server for managing session information on a network and switch a communication session during communication. Specifically, when a session switching request is received from a terminal, the session management server refers to the session information to be managed and notifies session change information for switching the session to the switching destination terminal. The terminal that has received the session change information changes the session connection destination and media according to the session change information.

  Non-Patent Document 1 is a document related to the session control protocol. Non-Patent Document 2 is a document related to a standard specification of an API for using a communication service provided by a communication carrier from a third-party application. Parlay X described in Non-Patent Document 2 is a simplified version of Parlay OSA, and uses a WEB service as a lower-level protocol. A platform that provides such an API is also referred to as SDP (Service Delivery Platform).

(2) Presence management function 330: manages presence information of terminals. Presence information is information regarding the online / offline status of the terminal 40 and the type of media (for example, voice, image) supported by the terminal. The SDP server 30 acquires presence information from the IMS server 20 using SIP.
(3) Session control function 340: Manages session information. It also controls session switching. The session information is information indicating the state of the session, for example, information relating to the presence / absence of session establishment, a call destination, a medium used, an IP address and a port number used. The SDP server 30 acquires session information from the IMS server 20 using SIP, and requests the IMS server 20 to switch the session using SIP.
(4) Web service providing function (reception function) 310: Provides an API (Application Program Interface) related to the above function as a WEB service to the outside. FIG. 3 is an example of an API provided by the SDP server 30 to the outside. The SDP server 30 provides an API to the outside using SOAP (Simple Object Access Protocol).

  The terminal 40 includes a SIP-UA (SIP-UserAgent), a browser, and various multimedia processing functions (for example, an audio processing function and a moving image processing function) not shown. The terminal 40 communicates with the IMS server (SIP network) by SIP-UA, and establishes various multimedia communication sessions (for example, voice communication by Voip, video communication by Mpeg) realized by various multimedia processing functions. To do. Further, the terminal 40 communicates with the Web server through a browser. As shown in FIG. 1, each user (for example, users A and B) possesses (uses) a plurality of terminals (user A has terminals 40a, 40c, and 40d, and user B has terminals 40d, 40e, and 40f). Each user needs to register the user and the terminal 40 that performs multimedia communication in the SDP server 30 via the IMS server 20 when performing multimedia communication. In the following description, it is assumed that terminals 40a to 40c possessed by user A and terminals 40c to 40f possessed by user B can communicate with each other by registration.

  Web server 10 communicates with terminal 40 and SDP server 30. For example, the Web server 10 provides information for switching the session to the terminal 40 using HTML. For example, the Web server 10 is an HTML screen that displays each terminal ID for identifying the terminals 40a to 40c and the media supported by each terminal as a character string for the browser of the terminal 40a possessed by the user A. When a character string of one terminal ID displayed on the screen is clicked (selected), information necessary for establishing a session with the terminal identified by the terminal ID (for example, the terminal ID) is stored on the Web server. When a command for transmission to the terminal 10 (hereinafter referred to as a “terminal designation command”) (for example, GET method, POST method) and a character string of one medium displayed on the screen is clicked, a session is performed by the media. Necessary information for establishing the media (hereinafter referred to as “media designation command”) (for example, ID for identifying the media) To send instructions to be sent to the eb server 10, the HTML screen incorporating. That is, the Web server 10 provides the terminal 40 with an HTML screen including information for switching sessions. Further, the Web server 10 receives various commands from the terminal 40 using HTML, and notifies the SDP server 30 using the API.

The function of the Web server 10 will be described in detail. The Web server 10 mainly has the following functions. FIG. 4 shows the relationship between the functions provided in the Web server 10.
(1) ID acquisition function 110: one registration terminal (for example, terminals 40a, 40b, 40c possessed by user A) that can communicate with another user (for example, user B) Based on the login information (for example, user name and password) of the terminal 40a), the terminal IDs of the registration terminals (terminals 40a, 40b, 40c) constituting the plurality of registration terminals including the one registration terminal are externally ( From the SDP server 30).
(2) Presence information acquisition function 120: Based on each terminal ID acquired by the ID acquisition function 110, each presence information of each registered terminal (terminals 40a, 40b, 40c) is acquired from the outside (SDP server 30).
(3) Session information acquisition function 130: Based on each terminal ID acquired by the ID acquisition function 110, each session information of each registered terminal (terminal 40a, 40b, 40c) is acquired from the external SDP server 30).
(4) Session information selection function 140: Selects session information including the IP address of one registered terminal (terminal 40a) from the plurality of session information acquired by the session information acquisition function 130.
(5) Information addition function 150: A terminal designation command for designating a registered terminal corresponding to each terminal ID as a terminal communicating with another user (user B) is added to each terminal ID acquired by the ID acquisition function 110 (setting) ) In addition, a media designation command for designating the media indicated by each session information as a media to be communicated with another user (user B) is added (set) to each session information acquired by the session information acquisition function 130. Further, information indicating that the registration terminal corresponding to the session information selected by the session selection function 140 is one registration terminal (terminal 40a) (hereinafter referred to as “own terminal information”, for example, an icon) is registered in the registration. It is added to the terminal ID of the terminal.
(6) Communication status transmission function 160: Each terminal ID to which a terminal designation command is added (the terminal information is added to one terminal ID), each presence information, and each session information to which a media designation command is added Are transmitted to one registered terminal (terminal 40a) as information indicating the communication state in association with each registered terminal (for each terminal 40a, 40b, 40c).
(7) Command processing function 170 (session switching function): A terminal designation command and a media designation command are acquired from one registered terminal (terminal 40a). Further, the terminal designation command and the media designation command acquired from one registered terminal (terminal 40a) are notified to the SDP server 30 using the API.

  In other words, the Web server 10 is one registration terminal (for example, a terminal) that constitutes a plurality of registration terminals 40 (for example, the terminals 40a, 40b, and 40c possessed by the user A) that can communicate with other users (for example, the user B). 40a), using HTML, the communication status of the plurality of registered terminals (for example, terminals 40a, 40b, 40c) with other users is output as a UI (GUI based on HTML) and is also displayed via the UI. Session (terminal and media) switching request (for example, switching request from voice communication by terminal a to video communication by terminal b) is received from the registered terminal. Details of the UI will be described later.

  Hereinafter, the sequence between the terminal 40, the Web server 10, and the SDP server 30 will be described with reference to FIG. Note that the sequence shown in FIG. 5 starts when the terminal 40c transmits login information (user ID) to the Web server 10 based on an instruction from the user A.

  The Web server 10 transmits login information to the SDP server 30 using the Web service providing function (acceptance function) 310 of the SDP server 30. Specifically, the Web server 10 transmits login information to the SDP server 30 using the API “loginUser”.

  Subsequently, the SDP server 30 verifies the login information by the subscriber management function 320. Further, the SDP server 30 transmits a verification result (permission) to the Web server 10 by the Web service providing function (acceptance function) 310. Specifically, the SDP server 30 transmits the verification result (permission) to the Web server 10 by the API “loginUser”.

  Subsequently, the Web server 10 transmits the collation result (permission) to the terminal 40c. In addition, the Web server 10 uses the Web service providing function (acceptance function) 310 of the SDP server 30 to use the terminal IDs (terminals 40a, 40b, and 40c) owned by the user A in the SDP server 30 (terminal IDs) Request terminal ID list). Specifically, the Web server 10 requests each terminal ID from the SDP server 30 using the API “getTerminalID”.

  Subsequently, the SDP server 30 searches (acquires) each corresponding terminal ID by the subscriber management function 320. Further, the SDP server 30 transmits each terminal ID corresponding to the Web server 10 by the Web service providing function (reception function) 310. Specifically, the SDP server 30 transmits each terminal ID corresponding to the Web server 10 by the API “getTerminalID”.

  Subsequently, the Web server 10 uses the Web service providing function (acceptance function) 310 of the SDP server 30 to configure a plurality of terminals 40 (terminals 40a, 40b, and 40c) that are identified by the terminal IDs to the SDP server 30. Request each presence information. Specifically, the Web server 10 requests each presence information from the SDP server 30 using the API “getPresenceInfo”.

  Subsequently, the SDP server 30 searches (acquires) each corresponding presence information by the presence person management function 330. Further, the SDP server 30 transmits each presence information corresponding to the Web server 10 by the Web service providing function (reception function) 310. Specifically, the SDP server 30 transmits each piece of presence information corresponding to the Web server 10 using the API “getPresenceInfo”.

  Subsequently, the Web server 10 uses the Web service providing function (acceptance function) 310 of the SDP server 30 to configure a plurality of terminals 40 (terminals 40a, 40b, and 40c) that are identified by the terminal IDs to the SDP server 30. Request each session information. Specifically, the Web server 10 requests each session information from the SDP server 30 using the API “getSessionStatus”.

  Subsequently, the SDP server 30 searches (acquires) each corresponding session information by the session control function 340. Further, the SDP server 30 transmits each session information corresponding to the Web server 10 by the Web service providing function (accepting function) 310. Specifically, the SDP server 30 transmits each session information corresponding to the Web server 10 by the API “getSessionStatus”.

  Subsequently, the Web server 10 selects session information including the IP address of one registered terminal (terminal 40c) from among the plurality of session information acquired from the SDP server 30.

  Subsequently, the Web server 10 adds (sets) a terminal designation command to each terminal ID acquired from the SDP server 30, and adds (sets) a media designation command to each session information acquired from the SDP server 30. Further, the Web server 10 adds its own terminal information to one terminal ID. In addition, the Web server 10 includes each terminal ID to which a terminal designation command is added (own terminal information has been added to one terminal ID), each presence information, and each session information to which a media designation command is added. A UI (for example, the UI shown in FIG. 6) associated with each registered terminal (each terminal 40a, 40b, 40c) is generated in HTML and transmitted to the terminal 40c.

  The terminal 40c displays a UI (for example, the UI shown in FIG. 6). 6 shows that the user A possesses three terminals 40 identified by terminal IDs “XXXXXX”, “YYYYY”, and “ZZZZZ”, and the media of the terminal 40 identified by terminal IDs “XXXXX” “YYYYY” are It shows that the media of the terminal 40 identified by the voice and terminal ID “ZZZZZ” are voice and video.

  The bold characters (terminal ID “XXXX”, presence information “online”, session information “voice”, terminal ID “ZZZZZ”, presence information “online”, session information “video”) in FIG. Indicates that the session is being established (online). Specifically, this indicates that the terminal identified by the terminal ID “XXXX” is establishing a voice session, and that the terminal identified by the terminal ID “ZZZZZ” is establishing a video session. The terminal identified by the terminal ID “YYYYY” indicates that the session is not being established.

  The underline attached to each terminal ID in FIG. 6 indicates a state in which a terminal designation command is added to each terminal ID. The underline attached to each session information indicates a state in which a media designation command is added to each medium. The own terminal information added to the terminal ID “ZZZZZ” indicates that the terminal 40 identified by the terminal ID “ZZZZZ” is the terminal displaying the UI (that is, the terminal 40c). .

  Further, a terminal designation command is added to each terminal ID, and a media designation command is added to the presence information. However, in the example illustrated in FIG. 6, the terminal designation command is added to all terminal IDs, but the terminal designation command may be added only to the terminal ID “YYYYY” of a terminal that has not established a session. In the example shown in FIG. 6, a media designation command is added to all session information, but session information relating to unused media (session information “voice” associated with terminal ID “YYYYY” and terminal The media designation command may be added only to the session information “voice” associated with the ID “ZZZZZ”.

  Subsequently, based on an instruction from the user A, the terminal 40c requests session switching via the UI. For example, in the example illustrated in FIG. 6, when the user A specifies only the session information “voice” of the terminal ID “ZZZZZ” and presses the “switch” button, the terminal 40 c is a terminal identified by the terminal ID “XXXX” Request to switch from a voice call session at 40 and a video session at terminal 40 (terminal 40c) identified by terminal ID “ZZZZZ” to a voice call session at terminal 40 (terminal 40c) identified by terminal ID “ZZZZZ” To do. For example, when there is one session information corresponding to the terminal ID, such as one session information corresponding to the terminal ID “XXXX” (only session information “voice”), only the terminal ID is changed. May be specified, and specification of session information may be omitted.

  The Web server 10 transmits a switching request to the SDP server 30 using the session control function 340 of the SDP server 30. Specifically, the Web server 10 transmits a switching request to the SDP server 30 using the API “requestSessionModification”.

  Subsequently, the SDP server 30 controls session switching by the session control function 340. For example, when switching the session from video to voice call at the terminal 40c (terminal ID “ZZZZZ”), the SDP server 30 holds an INVITE message for holding a voice communication session to the terminal 40 identified by the terminal ID “XXXX” or A BYE message for disconnecting the communication session is transmitted, and an INVITE message for switching from video to audio is transmitted to the terminal 40c (terminal ID “ZZZZZ”). In addition, the SDP server 30 transmits a session switching result by the session control function 340. Specifically, the SDP server 30 transmits the session switching result to the Web server 10 by the API “requestSessionModification”. Note that the Web server 10 generates a new UI based on the switching result and transmits it to the terminal 40c.

  As described above, according to the Web server 10, a session can be switched during communication in a general terminal such as a SIP terminal.
