Abstract: A method, an apparatus, and a system for managing a background data transfer policy, such that a policy control function network element can obtain a background data transfer policy corresponding to a terminal. The method includes: A first policy control function network element receives a first message. The first message carries a first identifier, and the first identifier may be a background data transfer reference identifier or an application function identifier. Then, the first policy control function network element sends a second message to a first data storage network element, facilitating obtaining of a background data transfer policy. The second message carries the first identifier. Finally, the first policy control function network element receives a third message from the first data storage network element. The third message includes a first background data transfer policy corresponding to the first identifier.

Abstract: This application relates to the field of communication technologies, and provides a slice access method, apparatus, and system, to reduce a probability that a terminal service fails because a slice that is not suitable for a current to-be-initiated service is matched. The slice access method includes: receiving one or more user route selection policy rules URSP rules from a network apparatus, and performing URSP matching according to the one or more URSP rules. At least one URSP rule in the URSP rules includes indication information, and the indication information indicates to match one or more preset URSP rules or match one or more preset route selection descriptors RSDs. The method is applied to a network slice access procedure.

Abstract: This application discloses a service processing method for a proximity service, a device, and a system, and relates to the field of wireless communication technologies, to resolve a problem such as inappropriate charging caused because a network side does not perform, in proximity service (ProSe) communication, service supervision or service management on a data packet transmitted by remote user equipment (UE) via relay UE. In this application, a first network element (for example, an access and mobility management function AMF network element or a session management function SMF network element) may obtain, based on relay information that is received from the remote UE and that includes a relay service code or first indication information indicating that the remote UE is to transmit a service in relay mode, policy configuration information for detecting or monitoring service data forwarded by the relay UE.

Abstract: A communications method, apparatus, and system for controlling admission of terminal behavior by a network side, where the method includes: A mobility management network element receives a first session request message from a terminal. The first session request message carries user route selection policy (URSP) identification information. Then, the mobility management network element obtains URSP policy information based on the URSP identification information, and the mobility management network element sends a second session request message to a session management network element. The second session request message carries the URSP policy information, and the URSP policy information is used to formulate a policy rule for the terminal.

Abstract: A policy control method performed by an enforcement function network element, where the enforcement function network element receives an update request to modify or remove a target packet flow description (PFD) associated with a target application identifier. For a session for which a first policy rule including the target application identifier is installed or activated, the enforcement function network element determines that data about an application corresponding to the target application identifier has been detected using the target PFD. The enforcement function network element further determines that start indication information of the application has been reported to a control function network element, and sends stop indication information of the application to the control function network element, which adjusts the first policy rule.

Abstract: This application provides a service configuration method, a communication apparatus, and a communication system. An AF configures a service request to an AMF by using an NEF, so that the AMF may request URSP configuration from a PCF when target UE is located in a target area. In this way, the PCF can effectively configure a URSP in a scenario in which an application service is dynamically deployed.

Abstract: In a location change reporting method, a session management function entity receives from a mobility management entity information including location change information of user equipment (UE) in a first presence reporting area (PRA), an identity of the first PRA, and an identity of a PRA set that includes the first PRA. The session management function entity identifies, based on the identity of the PRA set and locally stored PRA subscription information, a subscription entity that subscribes to location change events of the UE in the PRA set, and sends the identity of the first PRA and the location change information of the UE in the first PRA to the subscription entity.
