Method and system for call control

The embodiment method of the present invention provides a call control method and a call control system. The control of a TAS to a multimedia resource function processor enables a call link of a call connection to be performed between a MRFP dynamic or static access terminal equipment, and solves a RTCP problem generated during the process of realizing a complemental business, the control of the TAS to MRFP realizes the MRFP as a media streaming source to perform a function of a multimedia announce and must not be added in the call link repeatedly, to avoid the waste of the network resource; for an IMS circuit switching control function unit accessed newly, the function of the complemental business can be realized on the condition of not performing any amendment, to except from the interaction between the ICCF unit and the multimedia resource function processor, and to simplify the process.
