Abstract: Embodiments of this application provide a data analytics method and data analytics apparatus. The method includes obtaining, by a user plane data processing network element, at least one matching condition that is from a data analytics network element, where each of the at least one matching condition corresponds to at least one service type or at least one execution rule. The method further includes obtaining, by the user plane data processing network element based on the at least one matching condition, a service type associated with user plane data or an execution rule associated with the user plane data. Embodiments of this application implement data analytics by using the data analytics network element in a communications network.

Abstract: Embodiments of this application relate to a policy determining method and a communications apparatus. The method includes: obtaining, by a policy control network element, policy information from a data analytics network element; and determining, by the policy control network element, an execution policy of a service based on the policy information. In the policy determining method in the embodiments of this application, dynamic adjustment and refined management on the execution policy can be implemented.

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: 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: 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.
