Abstract  Abstract

A method of domain selection for routing control applied to a communication system including a Circuit Switched (CS) network and an IP Multimedia Subsystem (IMS) includes: obtaining call status(es) of a user in any one or both of the CS network and the IMS; selecting a domain via which an incoming call is to be delivered according to the call status(es) upon receiving a routing decision query request from a routing decision query entity and indicating the routing decision query entity to deliver the incoming call via the CS network or the IMS selected. The method provided by embodiments of the present invention selects the domain according to the call status(es) of the user in any one or both of the CS network and the IMS. Therefore the problem that two calls are respectively delivered via the CS network and the IMS at the same time may be avoided.
