Abstract:
A method for implementing call forwarding on user-determined user busy, including the following steps of: step 1: after receiving a session request routed by a CSCF from a calling side (401, 402), an IMS Circuit Switched Control Function (ICCF) on a called side establishing a call with a called terminal having IMS Centralized Service (ICS) capability (403), and then the called terminal ringing (410); step 2: sending, by the called terminal, a user-determined user busy message to the ICCF when a called user rejects the call (404); and step 3: notifying, by the ICCF, a Telecom Application Server (TAS) that the called terminal is in a user-determined user busy state (405), and the TAS initiating a procedure of call forwarding on user-determined user busy (406). A method for releasing the established media resources resources and session is also provided.
