Embodiment
To a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment only is used for explanation and explains the present invention, is not limited to the present invention below in conjunction with accompanying drawing.
Fig. 1 has shown the implementation method flow chart of serving calling RBT service certainly that the embodiment of the invention provides, and as shown in Figure 1, step comprises:
Step 101: the CRBT center connects with the calling subscriber after the calling subscriber calls out the called subscriber;
Step 102: the CRBT center is according to the calling RBT service request of calling subscriber's input, and the Query Information that will comprise rear subscriber number is sent to the signatory system that charges;
Step 103: the signatory system that charges is according to rear subscriber number, inquiring calling user profile, and said calling user information is sent to the CRBT center;
Step 104: the CRBT center plays to said calling subscriber with said calling user information.
Further, said step 102 is specially:
The media server at CRBT center is play the CRBT service provided to the called party that the called subscriber is provided with via server of color ring back tone service to the calling subscriber;
The calling subscriber sends to said media server with said calling RBT service request during listening to said CRBT service provided to the called party;
Said media server is sent to charge signatory system via server of color ring back tone service and Ring Back Tone service interface message processor (IMP) with said Query Information according to said calling RBT service request.
Further, said step 102 is specially:
The calling subscriber sends to said calling RBT service request the media server at CRBT center during listening to the acquiescence sound;
Said media server is sent to charge signatory system via server of color ring back tone service and Ring Back Tone service interface message processor (IMP) with said Query Information according to said calling RBT service request.
Further, said step 103 is specially:
The said Query Information that the signatory system interface machine of the charging of the signatory system that charges will be received is sent to the signatory system server that charges;
Charge signatory system server according to the rear subscriber number in the said Query Information, inquiring calling user profile, and said calling user information is sent to said server of color ring back tone service via the signatory system interface machine that charges.
Further, said step 104 is specially:
