Description

  The present invention relates to a session control method and a system device, and more specifically, a plurality of terminals each equipped with a messenger client and a web browser, and an arbitrary server that distributes information in response to requests from the plurality of terminals, A network system comprising a session management server that manages a session related to information communication between a plurality of terminals and an arbitrary server, and a presence server that manages presence related to the presence status of a user using the plurality of terminals The present invention relates to a session control method for controlling a session established between a plurality of terminals and an arbitrary server via a presence server, and a session control system apparatus directly used for the implementation.

  In recent years, in response to a request from a user of an information communication terminal (hereinafter simply referred to as “terminal”), each state of a plurality of content servers that distribute content such as audio and video is centrally managed on the network, or Session control servers for the purpose of centralized control of VoIP connection (VoIP: Voice over Internet Protocol) applied to Internet telephones and the like have come to be used.

  In addition, with the spread of messenger clients that manage presence related to the presence status of terminal users, presence servers that centrally manage the presence on the network have been introduced as servers similar to the session control server.

  When using this type of presence server, the user inputs the user identifier assigned to the user from the terminal and logs in to the presence server, and the user's current status, that is, the presence regarding the presence or absence of the user, Register on the presence server. As a result, each user participating in the network can grasp the status of all currently logged-in users by referring to the presence server, or send and receive instant messages between the logged-in users. And so on.

  Note that the SIP protocol (SIP: Session Initiation Protocol) is usually applied as a protocol implemented in the session control server, and SIMPLE, which is an extended version of the SIP protocol, is implemented as a protocol implemented in the presence server. A protocol (SIMPLE: SIP for Instant Messaging and Presence Leveraging Extensions) is generally applied.

  Conventionally, the session control server and the presence server have been used independently of each other because it is difficult to achieve cooperation between the two because of differences in their respective implementation protocols. For this reason, for example, it is naturally impossible to control the session in cooperation with the presence of the user.

  Here, in the SIP protocol and SIMPLE protocol implemented in the session control server and the presence server, respectively, SIP-URI (URI: Uniform Resource Identifier) which is an identifier for specifying the type of user or content is used. Since this SIP-URI is not assigned to hardware such as a terminal or a content server like an IP address (IP: Internet Protocol), the user always changes the same SIP-URI even if the terminal to be used is changed. You can continue to use the URI.

The details of the SIP protocol and SIMPLE protocol are described in Non-Patent Documents 1 and 2 below.
J. Rosenberg, "A Presence Event Package for the Session Initiation Protocol", January 31, 2003. J. Rosenberg et al., "SIP: Session Initiation Protocol", RFC3261.

  However, even if the SIP-URI is shared by the SIP protocol and the SIMPLE protocol, for example, a situation is assumed in which a certain terminal simultaneously logs in to the presence server and establishes a session via the session control server. In this case, when the user of the terminal moves to a different terminal (hereinafter referred to as “new terminal”) from the terminal used so far (hereinafter referred to as “old terminal”) and logs into the presence server, Is “logged in at the new terminal” and the session status is “establishing a session at the old terminal”, and an inconsistent state occurs between the presence and the session.

  In addition, since the presence management of the user by the presence server that has become popular in recent years and the communication control by the session control server are not linked, the user needs to use the presence server and the session control server separately. The operation becomes complicated.

  Furthermore, for example, when assuming a situation where the user has moved to the new terminal without ending the session established between the content servers through the old terminal, the user can terminate the connection between the old terminal and the content server. , It is necessary to return to the old terminal to end the session, which is inconvenient for the user.

  Here, the main objects to be solved by the present invention are as follows.

This is a functional means for transmitting session connection information comprising a combination of (one form) to the presence server 6 and managing a session state defined by the session connection information in accordance with an instruction from the presence server 6.

  Further, the terminal change determination unit 61 in the presence server 6 acquires the IP address assigned to the corresponding login terminal every time the user logs in using any of the plurality of terminals 3a, 3b,. In addition, based on the IP address and the connection source SIP-URI, the login terminal uses the old terminal (hereinafter referred to as “terminal 3a” in the plurality of terminals 3a, 3b,... For determining whether or not the terminal is changed to a new terminal different from the old terminal 3a (hereinafter referred to as "terminal 3b" in the plurality of terminals 3a, 3b,...). Means.

  The login IP address management database 62 uses the connection source SIP-URI as a key, and the new IP address and the old IP address (“2” in the present invention) acquired by the terminal change determination unit 61 for the new terminal 3b and the old terminal 3a, respectively. (Refer to FIG. 2 (a)), the terminal change determination unit 61 refers to the new / old IP addresses stored in the login IP address management database 62 to obtain the required IP addresses. Functions to perform terminal change determination.

  On the other hand, when the terminal change determination unit 61 determines that the login terminal has been changed, the session establishment determination unit 63 indicates that the user who is currently logged in using the new terminal 3b has previously used the old terminal 3a or the old terminal. The connection source SIP-URI transmitted from the session management unit 51 in the SIP server 5 and whether or not a session with the content server 4 using two or more terminals (not shown) including 3a is established and This is a functional means for determining based on the session connection information composed of the connection destination SIP-URI combination and the new IP address acquired for the new terminal 3b by the terminal change determination unit 61.

(Example method)
Next, an example of a method performed by the session control system apparatus α configured as described above will be described.

  First, when storing session connection information including a combination of a connection source SIP-URI and a connection destination SIP-URI transmitted from the session management unit 51 in the SIP server 5 in the in-communication session management database 64 in the presence server 6. The operation will be described.

  FIG. 3 is a flowchart for explaining the operation when storing session connection information in the in-communication session management database 64 shown in FIGS. 1 and 2.

  As shown in the figure, the session connection information is stored in the in-communication session management database 64 in the presence server 6. First, the user uses one of the terminals 3a, 3b,. A session with the content server 4 is established (ST1), and accordingly, the session management unit 51 in the SIP server 5 sends the connection source SIP-URI and the connection destination to the session establishment determination unit 63 in the presence server 6. This is performed each time session connection information consisting of a combination of SIP-URI is transmitted (ST2).

  Next, when session connection information is transmitted from the session management unit 51 in the SIP server 5, the session establishment determination unit 63 in the presence server 6 is currently used by the user specified by the connection source SIP-URI in the session connection information. In order to identify the logged-in terminal, the corresponding record of the user in the login IP address management database 62 is searched and the new IP address field is referred to, and the IP address (new IP address) stored in the new IP address field ) Is acquired (ST3).

  Then, the session establishment determination unit 63 in the presence server 6 performs communication while using the session connection information including the combination of the connection source SIP-URI and the connection destination SIP-URI transmitted from the session management unit 51 in the SIP server 5 as a key. In each corresponding field constituting the corresponding record of the user in the session management database 64, the new IP address (connected IP address) acquired in the processing of ST3 is stored together with the connection source SIP-URI and the connection destination SIP-URI. (ST4).

  In addition, the session management unit 51 in the SIP server 5 displays the session connection information including the connection source SIP-URI and the connection destination SIP-URI together with the information indicating that when the corresponding session is ended, as the presence server 6. In response to this, the session establishment determination unit 63 deletes the corresponding record related to the end of the session from the in-communication session management database 64.

  Next, a specific operation of the session control system apparatus α will be described. In this example, the user moves to the new terminal 3b without logging in the session established between the content servers 4 through the old terminal 3a, logs into the presence server 6, and operates the session from the new terminal 3b. A case will be described as an example (see FIG. 1).

  FIG. 4 is a flowchart for explaining the operation of the session control system apparatus α shown in FIGS. 1 and 2.

  As shown in the figure, the operation in the session control system apparatus α is as follows. The user logs into the presence server 6 using the new terminal 3b (ST11), and accordingly, the terminal change determination unit 61 in the presence server 6 The IP address assigned to the new terminal 3b, which is the login terminal at that time, is acquired (ST12), and the IP address of the login terminal (new terminal 3b) acquired for the user is stored in the login IP address management database 62. It starts by storing in the new IP address field in the corresponding record (ST13). In the login IP address management database 62, if a corresponding record related to the user already exists, it is handled by overwriting, and if it does not exist, a new record is created. .

  Next, the terminal change determination unit 61 in the presence server 6 uses the stored IP address (new IP address) and the IP address stored in the old IP address field in the corresponding record of the user (when logging in from the old terminal 3a). The acquired old IP address is compared (ST14).

  Next, when the new / old IP addresses are different (ST14; different), the session establishment determination unit 63 in the presence server 6 searches the corresponding record of the user in the communication session management database 64 and connects to the connected IP address field. To determine whether the user is communicating with the new IP address (establishing a session) (ST15), and if not communicating with the new IP address (ST15; No) ) By referring to the connected IP address field again, it is determined whether or not the user is communicating with other than the new IP address (ST16).

  Here, if the new / old IP addresses related to the user are different, the user is not communicating with the new IP address, and the user is communicating with other than the new IP address (ST16; Yes), this means that The login terminal is changed from the old terminal 3a used for the previous login to the new terminal 3b at the time of the current login, and the user performs a session with the content server 4 using the old terminal 3a in the past. Means that the session established between the content servers 4 through the old terminal 3a has been terminated and moved to the new terminal 3b and logged in to the presence server 6). The transmission unit 66 displays a Web page for guiding the type of operation for the session to be selected by the user. Instant message including the contents RL, and transmits to the messenger client 1 in the new terminal 3b (ST17).

  On the other hand, when the instruction command is transmitted from the session control unit 65 in the presence server 6, the session management unit 51 in the SIP server 5 performs session control such as disconnection or switching in accordance with the instruction command (ST20).

  When the processing up to the session control is completed, the session control unit 65 in the presence server 6 causes the terminal change determination unit 61 to search the login IP address management database 62, and the new IP in the corresponding record of the user of the new terminal 3b. The new IP address once stored in the address field is copied to the old IP address field for the next and subsequent processing, and the old IP address is set (ST21).

  If it is determined that the new / old IP addresses are the same in the process of ST14 (ST14; same), and it is determined that the communication is being performed with the new IP address in the process of ST15 (ST15; Yes), the process of ST16 If it is not determined in the process that communication is being performed except for the new IP address (ST16; No), and if it is determined that “no user operation” is determined in the process of ST18 (ST18; none), the terminal in the presence server 6 is changed. The determination unit 61 copies the new IP address temporarily stored in the new IP address field in the login IP address management database 62 to the old IP address field by executing the process of ST21 as needed, and the required old IP address. Set.
