  • Publication number: 20080146220
    Abstract: A CS domain call terminating system, includes a routing-controlled determination module that determines a call which has been subject to routing control in accordance with information carried in a received call initiation message. The routing-controlled determination module sends routing-controlled information of the call to a subsequent call flow control module, and the subsequent call flow control module determines and executes a subsequent call flow of the call in accordance with the received routing-controlled information. A network entity can obtain the routing-controlled information of the call during CS domain call termination of the invention, thereby avoiding repeated routing control and an indefinite subsequent call flow in the CS domain call terminating flow.
