CS domain call terminating system, method and network device

The invention claims a CS domain call end of the system and method, wherein core is: The routing control module and heating information in message to determine according to the call for receiving is carried out is a loop of the call control of; the call the routing control information transmission to the following call flow control module, a routing information control that by and carried out a call the call current of the following call flow control module switches. CS domain call of this invention ends of the process network entity to learn call the routing control information, comprising avoiding CS domain call ending a redundancy route control and call current is not explicit phenomenon current; The invention relates to a calling the static anchor point is a continuous topic, and realize the electrostatic anchor point is CS domain call end to the current, enabled calling to the casing CS domain normally; Of realizes is consummated CS domain call to end of the contacting layer and receiving to a calling realizability, which the static anchor point is usable target.
