Abstract: The present invention discloses a method, system, and apparatus for controlling Circuit Switched, CS, fallback. The method comprises: a network element which got calling information of the present call in CS domain notifying a Mobility Management Entity, MME, of the calling information; the MME notifying the called User Equipment, UE, of the calling information; the called UE determining whether the call performs CS fallback according to whether the user answers the call or according to pre-configured CS fallback policy. By applying the present invention, the CS fallback of ongoing call can be controlled by the called user which is in EPS network, therefore the usability of the user's EPS network service is ensured, the satisfaction degree of the user is improved, and the useless occupancy of the GSM/UMTS network resources is reduced.

Abstract: The present invention discloses a method for implementing a redirection service for UEs sharing a PUI in an IMS, comprising: when a UE in a PN registers at a PNM AS, the PNM AS fetching the UE Identity and establishing a corresponding relationship between the identity and the PUI; when determining to route an initial request message of a terminating call of a UE in the PN routed by an original S-CSCF to a configured UE sharing the PUI, the PNM AS adding the configured UE Identity into a redirected initial request message and sending it to the original S-CSCF which forwards the message to a redirection S-CSCF; and the redirection S-CSCF uniquely locating the configured UE according to the identity or both the identity and the PUI in the message. The present invention can redirect a session initial request to a configured UE sharing a PUI with other UEs.

Abstract: A domain transferring method for the single radio voice call continuity, a UE accesses via an LTE/SAE network, and sets up an IMS session anchored at a VCC AS with a remote node; when an S-IWF receives a handover request used to transfer the session to make the session access from a CS domain, the method comprises: the LTE/SAE network sends a handover command to the UE, the UE sends a handover complete message to a target access device after receiving the handover command; after the UE sends the handover complete message, or after the S-IWF receives the handover complete message, a release session notification message is sent to a VCC AS; after receiving the session release notification message, the VCC AS releases the session resources of the session.
