Description
Technical field
The present invention relates to the communications field, particularly, relate to a kind of method and one number service CSC server of realizing the one number service sequential ringing service.
Background technology
Network interconnection agreement (Internet Protocol, IP) IP multimedia subsystem, IMS (IPMultimedia Core Network Subsystem, IMS) be by third generation partner program (3rd Generation Partnership Project, 3GPP) a kind of IP-based network framework of Ti Chuing, made up an opening and service environment flexibly, support multimedia application, can provide abundant multimedia service for the user.
In the IMS system, key-course separates with operation layer, and key-course does not provide concrete business, only is responsible for providing to operation layer controlled function such as necessary triggering, routing and charging.The controlled function of key-course is to be finished by CSCF (Call Session ControlFunction is called for short CSCF).
CSCF is divided into Proxy Call Session Control Function (Proxy Call Session ControlFunction, abbreviation P-CSCF), query call conversation control function (Interrogating CallSession Control Function, be called for short I-CSCF) and three types of service call conversation control functions (Serving Call Session Control Function, abbreviation S-CSCF).(Application Server AS) forms operation layer, and concrete business service can be provided by a series of application servers.S-CSCF calls the business on the AS according to user's professional triggering of CAMEL-Subscription-Information control, realizes business function.AS and S-CSCF can be referred to as service equipment (Server Equipment is called for short SE).End-to-end equipment in the session is called subscriber equipment, and (User Equipment UE), is responsible for mutual with the user.In IMS, use SIP (Session Initialion Protocol, initial session protocol) to carry out communication between each functional entity.
The one number service sequential ringing service is a business important among the IMS, and under perfect condition, when the trigger condition of calling transfer satisfied, the media negotiation of calling out in the passage was finished, and when initiating new calling, can carry out normal media negotiation.But, in some cases, in the professional mutually nested complex scene of one number service sequential ringing service and preceding commentaries on classics class, may exist to call out in the passage and still carry out media negotiation, and the situation that the trigger condition of calling transfer has satisfied, this moment, the calling subscriber can't carry out media negotiation with the user who is transferred into, and caused the call transfer service failure.
For example, as shown in Figure 1, calling subscriber A calls out called subscriber B, and called subscriber B contracts the one number service sequential ringing service, and CSC is to user C, user D; When the one number service CSC AS of called subscriber B adopts B2BUA (Back-To-Back User Agent, back-to-back user agent) pattern, calling subscriber A is called forward path to the calling passage between the one number service CSC AS of called subscriber B; The one number service CSC AS of called subscriber B is called backward channel to the calling passage between the different CSC users, and wherein, CSC is called backward channel 1 to the calling passage of user C; CSC is called backward channel 2 to the calling passage of user D; Under the scene of carrying out end-to-end media negotiation, forward path is unique, and backward channel is not unique.
With reference to Fig. 1, if user C changes class business or one number service sequential ringing service before also contracting and having, when the trigger condition of called subscriber B one number service CSC satisfies, CSC calling party C, this moment is if trigger one number service sequential ringing service or the multiple forwardings business of user C, and call out and finally land to user N, when calling subscriber A and user N carry out media negotiation by backward channel 1 and forward path, the one number service CSC AS of called subscriber B is CSC calling party D owing to trigger condition satisfied (such as overtime CSC), set up backward channel 2, and release backward channel 1, and owing to carrying out the media negotiation of calling subscriber A and user N in the forward path, do not finish under the situation of proposing/replying (offer/answer) model, can't carry out the media negotiation of calling subscriber A and user D.
Figure 2 shows that when forward path carries out media negotiation that called subscriber B CSC trigger condition satisfies, the Signalling exchange that the one number service CSC AS of called subscriber B carries out comprises:
Step 201: the one number service CSC AS of called subscriber B (is called for short: AS) send release message (Cancel) to user N;
Step 202:AS sends to user D and invites (Invite) message, sets up backward channel 2;
Step 203: after user D received Invite message, the response message (18x) to AS returns Invite message carried the media information of himself in 18x message;
After step 203:AS receives 18x message,, the 18x message of carrying the medium of user D calling subscriber A can't be sent to, media negotiation can't be carried out, the CSC call failure owing to do not finish the offer/answer model in the forward path.
