In the IMS business system, key-course separates with operation layer, and key-course does not provide concrete business, and functions such as necessary triggering, route, charging only are provided to operation layer.Professional triggering and controlled function are by CSCF (CSCF, Call Session Control Function in the key-course; Be divided into and act on behalf of Proxy, three types of inquiry Interrogating and service Serving, that wherein take the main responsibility is the CSCF of Serving type, i.e. S-CSCF; The Interrogating type is optional) finish.Operation layer is to be made up of a series of application servers (AS, Application Server), and concrete business service can be provided.AS can be an independent entity, also may reside among the S-CSCF.Key-course (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 (SE, Server Equipment).End-to-end equipment in the session is called subscriber equipment (UE, User Equipment), is responsible for mutual with the user.These functional entitys use SIP (Session Initiation Protocol) agreement communication.
Session blind transferring service is a kind of business among the IMS, this business allows the user after session is set up, and by transfer party session is transferred on the equipment of diverting the aim, and makes the side of being transferred no longer converse with transfer party, transfer and the conversation that diverts the aim, wherein the transfer party and the side of being transferred are the both sides of original conversation.Convention business also is a kind of business among the IMS, and this business allows many people to converse simultaneously, and promptly a people speaks, and other people can both hear that convention business SE is managing all meetings on it, and each meeting is a unique identification with the meeting contact address again.If the user has opened blind transferring operation, carrying out convention business again simultaneously, then two kinds of business exist mutual because need to use identical message.
Fig. 1 is the mutual basic messae flow process figure of existing blind transferring operation and convention business, description be that UE-A has opened blind transferring operation, UE-A and UE-B have set up session, UE-A has created convention business again, then invites UE-B to add the process of meeting, its step is as follows:
101, UE-A and UE-B have set up Multimedia session, and because of UE-A has opened blind transferring operation, so blind transferring operation SE is on the path of session signaling;
102, UE-A has created meeting, and equally because of UE-A has opened blind transferring operation, blind transferring operation SE is also on the signaling paths of this session, and blind transferring operation SE has write down the meeting contact address and UE-A is conference creation person;
103, the session of UE-A request transfer UE-B so that UE-B adds meeting, sends REFER (transfer) message such as transfer party UE-A and give the side of being transferred UE-B, and the information points in the Refer-To header field diverts the aim to meeting---the meeting contact address;
104, blind transferring operation SE receives transfer request, thinks to carry out blind transferring operation, changes the address of blind transferring operation SE into so will divert the aim, and transmits amended Transfer Message;
105, UE-B receives transfer request, agrees to shift, and such as responding " 202 Accepted " message, receives the response by way of blind transferring operation SE;
106, blind transferring operation SE transmits and receives the response to UE-A;
107, the session that will shift of UE-B FEFO is such as sending BYE message to UE-A, message travels blind transferring operation SE;
108, blind transferring operation SE transmits the end session message of UE-B to UE-A;
109, UE-B is according to transfer request, to diverting the aim, i.e. and blind transferring operation SE, the request of making a call is such as sending INVITE (invitation) message;
110, blind transferring operation SE receives call request, and call targets is revised as the meeting contact address, transmits the call request of UE-B then by this address;
111, because of the meeting contact address on convention business SE, convention business SE receives call request, with its therewith the meeting of appointment be associated, and answering call is such as responding " 200 OK " message;
112, reply and receive the response by way of blind transferring operation SE, blind transferring operation SE transmits to reply to respond and gives UE-B;
113, since then, UE-B original session that is through with, and set up session with convention business SE, thus added in the middle of the meeting that UE-A creates.
Come out the flow process among Fig. 1 is abstract, form outline flowchart shown in Figure 2, can more clearly find out the defective of prior art thus, its step is as follows:
201, UE-A request UE-B shifts its session to the meeting contact address, and request is by way of blind transferring operation SE;
202, blind transferring operation SE revises and diverts the aim to after own, transmits transfer request and gives UE-B;
203, UE-B receives transfer request, the calling transfer target---blind transferring operation SE;
204, blind transferring operation SE receives message related to calls, revises to divert the aim once more to be the meeting contact address, gives real diverting the aim (on convention business SE) by this address with forwards then.
Based on existing implementation, the transfer request that will belong to convention business because of blind transferring operation SE has been treated as and has been belonged to blind transferring operation, make the call request of follow-up UE-B unnecessarily pass through blind transferring operation SE, increase signaling paths and the unnecessary retouching operation that diverts the aim, also increased the unnecessary blind transferring operation expense of UE-A simultaneously.
