Abstract: A session migration method includes sending, by a transmission management apparatus, registration request cancellation information to a subscriber information management apparatus in response to user plane security enforcement information of a packet data unit (PDU) session failing to match user plane encryption protection information of an evolved packet system (EPS). The registration request cancellation information is useable to indicate that the PDU session fails to support migration to the EPS, and the PDU session has been registered with the subscriber information management apparatus.

Abstract: When an EBI needs to be assigned to an EPS bearer to which a QoS flow is mapped in an EPS, whether user plane security enforcement information of a PDU session matches user plane encryption protection information of the EPS is determined, that is, whether a user plane capability of the EPS can meet a user plane security requirement of the PDU session is determined. The EBI is assigned to the EPS bearer only when the requirement is met. Otherwise, the EBI is not assigned to the EPS bearer or the EBI is released if the EBI has been assigned. In this way, when UE moves from a 5GS to the EPS, the EPS bearer is prevented from using an EBI that does not meet the user plane security requirement for data transmission.

Abstract: The present disclosure relates to session information management methods. One example method includes sending, by a session management function (SMF) network element, identification information of a terminal device, a data network name (DNN), and slice information to a data management network element to request first subscription data that is of the terminal device and that is associated with the DNN and the slice information, where the slice information is used to identify a network slice served by the SMF network element, and receiving, by the SMF network element, the first subscription data from the data management network element.

Abstract: A method for sending an end marker, a device, and a system, where the method includes receiving, by a source access node (AN) through a source path between the source AN and a core-network user-plane device, a first end marker sent by the core-network user-plane device. The method further includes generating, by the source AN, N second end marker(s) based on the first end marker, where N is a number of source data radio bearers (DRBs) corresponding to the source path, and sending, by the source AN, the N second end marker(s) to a target AN through a forwarding path corresponding to the source path.

Abstract: This application provides a QoS flow control method and an apparatus. An SMF network element receives first indication information sent by an access network apparatus, where the first indication information is used to indicate that a first QoS target of a QoS flow cannot be met; and the SMF network element does not process the QoS flow if the SMF network element receives second indication information in a first preset time; or the SMF network element deletes or modifies the QoS flow if the SMF network element does not receive second indication information in a first preset time, where the second indication information is used to indicate that the first QoS target can be met.

Abstract: Example communication methods and communications apparatuses are provided to verify a user equipment route selection policy (URSP) used by a terminal apparatus. One example communication method includes obtaining information about a first application of at least one packet data unit (PDU) session, where the information about the first application is determined based on a first URSP, and then sending the information about the first application to a second network element, where the information about the first application is used to verify whether information about a second application of the at least one PDU session matches the information about the first application, and the information about the second application is information about an application to which a data packet in the at least one PDU session belongs.
