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.

Abstract: The present invention discloses a single radio voice call continuity handover method and apparatus. An MME records whether a bearer deletion request message sent by a gateway device is received, and if the MME determines that the bearer deletion request message is received, the MME does not send a bearer deletion instruction message to the gateway device, and does not delete a local voice service bearer resource. Therefore, after the MME performs voice service bearer deletion on an IMS side, the MME does not perform voice service bearer deletion on an EPS side, thereby avoiding a conflict in an SRVCC process. Alternatively, when a reason for session termination is SRVCC handover, a PCRF does not send a re-authentication request message to the gateway device, that is, the gateway device does not perform a voice bearer deletion process on the IMS side, thereby avoiding a conflict in an SRVCC process.

Abstract: Embodiments of this application relate to the field of communications technologies, and disclose a service setup method and a device, to resolve a problem that a service cannot be normally executed. The method includes: receiving, by an access network device, a first setup request; sending a first setup response to a first core network device or a first service application server, where the first setup response is used to indicate that the access network device accepts the first setup request; when radio channel quality of a first cell of a first network in which UE is located does not satisfy a service requirement of a first service carried in the first setup request, handing over the UE to a second cell of the first network, or handing over the UE to a third cell of a second network.

Abstract: A device and a method for implementing a data service in order to avoid generating an unnecessary data usage fee for user equipment (UE) and further avoid data usage waste after a data service switch of the UE is turned off. The method includes determining, by a first network-side device, a status of a data service switch of UE, and sending, by the first network-side device, a first notification message to a second network-side device when the data service switch of the UE is turned off, where the UE is already registered with a network, the first notification message includes first instruction information and an identity of the UE, and the first instruction information instructs the second network-side device to skip charging for data packets of the UE flowing through the second network-side device.
