Abstract
The present invention discloses a network handover method, where in a process of implementing circuit switched fallback, handover from an LTE network to a 2G or 3G network is triggered, so that UE can be directly handed over from the LTE network to a CS domain of the 2G or 3G network, and the network or the UE uses a session generated in the process in which the called party is handed over from the LTE network to the CS domain of the 2G or 3G network. Therefore, a common called procedure does not need to be performed after the UE is handed over from the LTE network to the 2G or 3G network, thereby shortening time for which a user waits before the voice session is connected.
