Abstract
The present invention discloses a method for handoff from a PS domain to a CS domain, including: the MS obtaining a handoff number and initiating a CS domain session request by taking the handoff number as a called number; a network side associating the CS domain session request to an original session of the MS and notifying the MS to finish an air interface handoff; the MS notifying the network side to finish a network side handoff. The present invention also discloses a CS domain access network simulating entity, a PS domain access network and an MS thereof. By adopting the solution, it is not necessary to modify existing network cells in the CS domain network, and the routing process is simplified. It is not necessary for handoff control layer entities to simulate original services of the CS domain. There is no new requirement for functions of the MGCF entity.
