Abstract: A data service control method and a related device are disclosed. The method includes: determining, by a PGW, a status of a data service switch of UE; if the status of the data service switch is that the data service switch is turned off, after the PGW receives a first data packet that comes from or goes to the UE, determining, by the PGW, whether the first data packet belongs to a specified type; and forwarding, by the PGW, the first data packet if the first data packet belongs to the specified type; or discarding, by the PGW, the first data packet if the first data packet does not belong to the specified type. During implementation of embodiments of the present disclosure, when the data service switch of the UE is turned off, data traffic of the UE can be saved.

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.
