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: A service processing method and an apparatus are provided. The method may include receiving, by an access network device, a connection setup message sent by user equipment (UE), where the connection setup message includes first voice session indication information that indicates that the connection setup message is sent due to a Voice over Long Term Evolution (VoLTE) voice session. The method may also include preferentially allocating, by the access network device within a first time period that is after the access network device receives the connection setup message, an uplink transmission resource to the UE if receiving a resource scheduling request message sent by the UE.
