Abstract
The present invention discloses a network handover method. After receiving a request message that requests circuit switched fallback (CSFB) and that is initiated by a UE located in an LTE network, an MME requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network; and after receiving a radio access bearer (RAB) sent by the MSC, the MME sends the RAB to the eNB, so that the RAB is sent by an eNB to the UE, where the RAB is a RAB whose domain identifier is a packet switched (PS) domain, or the RAB is a PS RAB. Therefore, the UE can be handed over to a PS domain of the 2G or 3G network in a manner of being handed over from the LTE network to the CS domain of the 2G or 3G network.
