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: This application provides a parameter determining method and a communications entity. The method includes: When UE is in a system in which an EPS network and a 5GS network interwork, the UE is currently located in the 5GS network, and used QoS parameters include an authorized UE AMBR and an authorized session AMBR of a session. Because of movement of the UE, the UE needs to be handed over to the EPS network, and QoS parameters that need to be used for the UE in the EPS network include an authorized UE AMBR and an authorized APN AMBR. The authorized APN AMBR is determined by a first communications entity based on at least one of a subscribed APN AMBR or the authorized session AMBR of the PDU session, and the authorized UE AMBR is determined by a second communications entity based on the authorized APN AMBR.

Abstract: Embodiments relate to the field of communications technologies, and provide a service communication method and a device, to resolve a problem that a service cannot be normally executed because a radio resource is forcibly allocated to UE after a service establishment request is received. In this method, a service establishment request sent by a service application server can be received by an access network device. A notification message to the service application server can be sent by the access network device. The notification message can carry information reflecting an actual network status of a cell in which UE is located, and the actual network status of the cell in which the UE is located is used by the service application server to determine updated radio channel quality requirement information. This method can be performed in a process of establishing a service and performing service communication.

Abstract: The present disclosure relates to example service processing methods and devices. In one example method, a request message for setting up a Voice over Long Term Evolution (VoLTE) service for a user equipment (UE) in a packet switched (PS) domain is received by an Internet Protocol multimedia subsystem (IMS) core network device. The IMS core network device triggers a circuit switched fallback (CSFB) service of the UE after determining that the VoLTE service cannot be set up in the PS domain.

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: Embodiments of the present invention provide an inter-RAT measurement method, a related apparatus, and a measurement system. The method includes: sending, by a control node in a first RAT network, a measurement control message to UE in the first RAT network, where the measurement control message is used to instruct the UE to measure signal quality of a second RAT network in a dormant period of a first C-DRX cycle; disabling, by the control node, a first inactive-period timer, where the first inactive-period timer is used to perform timing for the control node in an active period of the first C-DRX cycle; and performing, by the control node, downlink transmission for the UE in the active period of the first C-DRX cycle. The present invention is applicable to the wireless communications field.

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: 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: A communication method includes: sending, by an MME, a bearer setup request message to an eNodeB, where the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message, sending, by the MME, an indication message to the user equipment, where the indication message is used to indicate that a voice over VoIMS of the user equipment is unavailable. When setup of a voice bearer of a VoLTE call fails, the user equipment is notified that a VoLTE is unavailable, so that the user equipment can be prevented from continuing attempting to initiate the VoLTE call and exacerbating cell congestion.
Abstract translation: 通信方法包括：由MME向eNodeB发送承载建立请求消息，其中承载建立请求消息用于指示eNodeB为用户设备建立语音承载; 并且当MME接收到eNodeB响应承载建立请求消息发送的承载建立失败消息时，由MME向用户设备发送指示消息，其中指示消息用于指示VoIMS上的语音 的用户设备不可用。 当VoLTE呼叫的语音承载的建立失败时，向用户设备通知VoLTE不可用，从而可以防止用户设备继续尝试发起VoLTE呼叫并加剧小区拥塞。
