Abstract:
1. A method of handover for a user equipment (UE), comprising: receiving, by an evolved NodeB (eNB), in a first network, a measurement parameter from the UE; wherein the first network is a packet switched (PS) domain network; analyzing, by the eNB, that whether a neighbor cell belongs to a circuit switched (CS) domain, and judging whether the neighbor cell has CS capability according to the measurement parameter reported from the UE; determining, by the eNB, the relocation is a PS domain-CS domain relocation if the neighbor cell belongs to the CS domain and the neighbor cell has the CS capability; sending, by the eNB, a relocation request to a target mobility management entity, MME, in the PS domain network, so as to enable the MME sends a relocation command to an evolved mobile switching centre (eMSC); wherein the relocation request carries a relocation cause value, a target cell list and a context ID of a bearer that needs to be forwarded to a peer entity, and the relocation cause value indicates that the relocation is a PS domain-CS domain relocation.
