4; Switch according to CAMEL-Subscription-Information (for example; Identify called unreachable through DP2 sign caller triggering, the triggering of DP3 sign access code, DP4) to integrated business access gateway (Integated Service Access Gateway; Abbreviate ISAG as) (Signaling Interface Unit SIU) send to trigger service message (that is IDP message) in the signaling interface unit;
5, after parlay module (API that open service inserts) is received the message (address events notification message) from SIU, generate session;
6, after the service logic controller is received the trigger request of parlay module, send and should ask, and require to preserve session to pretreatment module (Predeal module);
7, Predeal carries out the preservation of session according to preserving the session requirement;
8, Predeal is with professional (Webservice) module of trigger request notice Web of user A;
9, the webservice module notifies the trigger request of user A to SP;
10, after SP receives trigger request, indication webservice module: let user A and user B set up conversation;
11, the Webservice module is given the Predeal module with the SP indication notice of receiving;
12, set up timer after the service logic controller is notified, this timer is used for regularly keeping heartbeat to get in touch with the Predeal module;
13, the indication of service logic controller is set up conversation with user B, exhales the message of user B to be sent to the parlay module commentaries on classics;
14, after the parlay module receives that the message of user B is exhaled in commentaries on classics, indication and the message that user B sets up conversation are sent to SIU;
15, SIU is connected to caller A according to the on-site switch of Indication message indication user of its reception the called B of appointment;
16, calling and called the user converse;
17, in communication process, the service logic controller is regularly preserved session to the application of Prdeal module;
18, SP issues session identification (Callid) indication notice Webservice module and finishes corresponding calling;
19, the Webservice module should indicate notice to give the Predeal module;
20, Predeal module informing business logic controller finishes corresponding calling;
21, the service logic controller sends to the Prdeal module and discharges session operation indication;
22, the service logic controller sends to the Parlay module and discharges session operation indication;
23, Parlay module indication SIU discharges session;
24, the on-site switch of SIU instruction user cuts off and is connected with user's speech channel;
25, switch is taken out stitches to the user, end of conversation.
