    摘要： A method and Voice Call Continuity (VCC) application server to perform trunk optimization for an Internet Protocol (IP) Multimedia Subsystem (IMS) voice call between an originating User Equipment (UE) and a terminating UE, which are homed in a CS network, is provided. The method includes receiving a request from the originating UE for an IMS voice call with the terminating UE, determining whether the VCC application server serves both the originating UE and the terminating UE, and, if it is determined that the VCC application server serves both the originating UE and the terminating UE, controlling to establish a bypass bearer for the IMS voice call between the originating UE and the terminating UE that bypasses the CS network.
