Background technology
Supplementary service is the business that the basic telecommunications business is made amendment or replenished, and supplementary service must provide with corresponding basic service, and the supplementary service that provides of network at present is commonly used following a few class:
One, preceding commentaries on classics class comprises: unconditioned call connection (CFU), chance mobile client busy call forward (CFB), chance no-answer call connection (CFNR), the chance unreachable Call Forwarding of mobile client (CFNR) etc.
Unconditioned call connection (CFU): refer to that all incoming calls that serviced mobile client can allow the networking will call out him are connected to another setting number.
Meet mobile client busy call forward (CFB): refer to when running into called mobile client and do, incoming call is connected to another preset number.
Meet no-answer call connection (CFNR): refer to when called mobile client no response is met at the networking, incoming call is connected to another preset number.
Meet the unreachable Call Forwarding of mobile client (CFNR): refer to when the registration of mobile client end, do not have SIM card or Radio Link to block or mobile client leaves wireless coverage area, and can't find the time, incoming call is connected to another preset number.
Two, calling transfer (CT): the calling transfer that can make the client will set up (promptly entering talking state) is given the third party.The mobile client that carries out calling transfer can be the calling party, also can be the callee.
Three, Call Waiting (CM): can notify the called mobile client that is in busy condition to have incoming call to wait for, select whether to accept or refuse this waiting calling by the callee then.
Four, call blocking class comprises:
All incoming calls of locking (BAIC): mobile client can't receive any incoming call.
All outbound calls of locking (BAOC): except that urgent call, do not allow any outbound call.
Below, be example to call forwarding on busy, the implementation procedure of prior art supplementary service is described:
Terminal A calling terminal B;
The mobile switching centre of described calling incoming terminal B;
Described mobile switching centre and described terminal B are mutual, learn that terminal B converses;
Described mobile switching centre and attaching position register (HLR) are learnt the described terminal B divert when busy business of having contracted alternately, and obtain the transferred number that described HLR returns.
Then the call request of terminal A is sent to the terminal of described transferred number correspondence.
In research and practice process to prior art, the inventor finds that there is following problem in prior art:
In case it is all to come into force for all calling numbers that the user opens supplementary service, no matter from the calling of what number, reach the trigger condition of supplementary service, then system automatically performs this user's supplementary service, then can but for the user, may just wish for some number avalidation, promptly wish opposite end number that can trigger compensation business is limited, therefore current supplementary service implementation method can't satisfy the demand of user to more detailed-oriented business service.
