A, opens Call Collision business when user opens an account, by client, business datum is issued to HSS server;
B, is issued to the CSCF (CallSessionControlFunction, CSCF) of service from HSS server by the business datum of Call Collision business when user initiates to register;
C, when calling subscriber makes a call, CSCF detects in calling and called and the Call Collision business that had user to open then caller information, called party information and calling ID is informed to service server (AS);
D, the CSCF of service detects called subscriber busy, then send query messages to service server;
E, the user profile that service server inquiry is preserved, contrast caller and calledly if so, then enter step f whether simultaneously at call peer, otherwise instruction CSCF continues basic call;
F, two-way calling associates by service server instruction CSCF, and removes two-way independent call Zhong mono-tunnel, by another road call through according to Call Collision processing policy instruction CSCF.
Preferably, business datum described in step a comprises service server (AS) address, Call Collision processing policy etc.
Preferably, in step c, caller information, called party information and calling ID are informed to service server by SIPInfo message by CSCF.
Preferably, in step f, service server instruction CSCF is by a road call tear down formerly, by a posterior road call through.
Compared with prior art, the invention has the advantages that: 1, business realizing based on IMS solves two users and dials the unsuccessful problem of collect call simultaneously, operator can be supplied to user for improving Consumer's Experience as basic service, optimization system resource uses, also can need customization according to customer service, be supplied to specific user's such as emotional affection network users etc. as value-added service.2, realize simple, the network element relating to IMS is few, purely realizes with trafficwise, does not relate to hardware modifications.3, adopt general standards and norms, namely intelligent network and SIP realize, and easily can solve the problem interconnected between distinct device supplier or different operators.
