Abstract: The present disclosure relates to data transmission methods and apparatus. One example method includes receiving, by user equipment, a first message sent by a control plane network element or a user plane network element, where the first message includes a correspondence between a first quality of service identifier NQI and a first reflective quality of service identifier (RQI), obtaining, by the user equipment, a second message sent by the user plane network element, and if the second message does not carry a second RQI, generating, by the user equipment, a first quality of service rule based on the second message and the correspondence between the first NQI and the first RQI, where the second RQI is used to instruct the user equipment to activate a reflective quality of service (RQ) mechanism.

Abstract: This application provides a session migration method and apparatus. When a terminal apparatus moves from a 5GS to an EPS, the terminal apparatus needs to establish a corresponding PDN connection in the EPS for a PDU session in the 5GS. Before establishing the PDN connection, the terminal apparatus needs to determine that a user plane security status of the PDU session matches user plane encryption protection information of the EPS. This avoids that a PDU session that does not satisfy a user plane security requirement is migrated to the EPS, and reduces unnecessary signaling overheads.

Abstract: Embodiments of the present application relate to the wireless communications field, and in particular, to a session management method and a session management network element. The session management method includes: receiving, by a first control plane network element, a user equipment UE context response message from a second control plane network element, where the UE context response message carries a first session message, and the first session message is a pending session message; and sending, by the first control plane network element, a second session message to user equipment according to the UE context response message. According to the session management method and the session management network element in the embodiments of the present application, a session can be managed in a scenario in which a control plane connection of user equipment changes.

Abstract: The present disclosure relates to a mobile edge platform switching method. In one example method, an application identity of a source application instance is received by a second mobile edge platform from a first mobile edge platform. The first mobile edge platform provides a service for the source application instance. The source application instance provides a service for a user equipment. A target application instance of the user equipment is determined based on the application identity. The application identity of the source application instance is the same as an application identity of the target application instance. The second mobile edge platform provides a service for the target application instance. A switching notification message is sent by the second mobile edge platform to the target application instance. The switching notification message is used to instruct the target application instance to provide a service for the user equipment.
