Abstract: A session management function entity selection method includes receiving a reselection indication and information about a first session of user equipment UE from a first session management function entity, where the reselection indication is used to instruct to reselect a session management function entity; saving a correspondence between the first session management function entity and the information about the first session according to the reselection indication; receiving a session establishment request message, where the session establishment request message carries the information about the first session; determining a second session management function entity different from the first session management function entity; and sending a session management request to the second session management function entity.

Abstract: A method for determining a policy control network element, in which a mobility management network element obtains first indication information, where the first indication information indicates to select a same policy control network element as a policy control network element for access and mobility management and a policy control network element for session management; the mobility management network element receives a session establishment request from a terminal for establishing a first session; and the mobility management network element sends second indication information and information about a first policy control network element to a session management network element based on the first indication information, where the second indication information indicates to select a same policy control network element as a policy control network element used for access and mobility management and a policy control network element used for session management of the first session.

Abstract: In a communication method when a preset quantity of terminal devices is allowed to simultaneously use a user identifier and a terminal device expects to use the user identifier, the terminal device sends a first message including the user identifier to a first network element. The first network element determines, based on information about the user identifier, whether the first terminal device is allowed to use the user identifier.

Abstract: A method for determining a network quality of service (QoS) flow, a network element, and a system include receiving, by a session management function network element, a policy and charging control (PCC) rule from a policy control function network element, where the PCC rule includes QoS parameters, the QoS parameters include standardized QoS parameter indication information and a non-standardized QoS parameter, and the non-standardized QoS parameter includes at least one attribute comprised in a standardized QoS parameter corresponding to the standardized QoS parameter indication information and a corresponding value of the at least one attribute, and determining, by the session management function network element based on the standardized QoS parameter indication information and the non-standardized QoS parameter, a QoS flow corresponding to the PCC 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 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.

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.
