Abstract: In a network handover method, after UE located on an LTE network initiates a request message that requests CSFB, an MME instructs an enodeB to move the UE from the LTE network to a 2G or 3G network, and requests an MSC to hand over the UE from the LTE network to a CS domain of the 2G or 3G network for the CSFB, so that the 2G or 3G network allocates a CS domain resource to the UE. Further, by determining that an IMS voice session does not exist, it is identified that the handover of the UE from the LTE network to the CS domain of the 2G or 3G network is triggered by the CSFB, so as to ensure that handover from the LTE network is properly performed.

Abstract: The present invention discloses a voice resource saving method, including: an MME sends a notification message to an eNodeB, which is used to instruct the eNodeB not to hand over, for a non-voice service, a UE from a LTE network to a CS domain of a 2G or a 3G network. Or, when an MSC determines that the circuit domain service is a non-voice service, the MSC sends a bearer release message to a base station to instruct the base station to release the voice resource. According to the the present invention, during implementation of a non-voice service, a handover of UE from an LTE network to a CS domain of a 2G or 3G network may not be triggered, or a voice resource reserved in the CS domain of the 2G or 3G network is released.

Abstract: In a backup method, a source storage device sends data to a backup storage device. The source storage device contains a processor and a cache. The processor receives a write data request which includes target data. And then, the processor reads a period ID recorded in a period ID table, wherein the period ID is corresponding to a first period. Next, the processor modifies the write data request by attaching the period ID to the target data and writes the modified write data request into the cache. After a backup task corresponding to the period is triggered, the processor obtains data received during the period corresponding to the period ID and sends the obtained data to the backup storage device.

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.

Abstract: The present invention relates to the field of communications technologies and discloses a method for selecting an LTE network and a device, so as to ensure continuity of a PS service, avoid unnecessary inter-PLMN handover, and improve user experience. The method mainly includes: acquiring, by an MSC/VLR, an identity of an LTE PLMN in which UE is registered, where the MSC/VLR is an MSC/VLR after the UE falls back to a 2G/3G network because of performing a CS service; and sending, by the MSC/VLR, a notification message to the UE, where the notification message includes the identity of the LTE PLMN, which is used to indicate the LTE PLMN that the UE returns to, and the LTE PLMN is used as a registered PLMN in the 2G/3G network. Embodiments of the present invention are mainly used in a process of fallback to an LTE network after a CSFB service ends.
