Abstract: This application provides a network connection configuration method and an apparatus. The method is as follows: After a terminal device obtains network configuration information of an application in the terminal device, the terminal device sends the network configuration information to a core network control plane network element, so that the core network control plane network element may determine a network connection that is of the application and is between the terminal device and the data network and that meets the network configuration information.

Abstract: The present disclosure relates to a user-plane protocol stack determining method, a control-plane network element, and a system. The method includes: obtaining attribute information of a service of a terminal; determining, based on the attribute information of the service, a user-plane protocol stack used to transmit the service, and determining a user-plane network element serving the terminal; and sending protocol stack type indication information of the user-plane protocol stack to the user-plane network element and an access-network network element, where the protocol stack type indication information is used to indicate the user-plane protocol stack corresponding to the user-plane network element and the access-network network element. Therefore, a to-be-used user-plane protocol stack is determined according to different service requirements of the terminal, thereby flexibly meeting the service requirements of the terminal.

Abstract: A PDN connection release method is disclosed. For one example, a user equipment may determine a service transmission status of a target packet data network PDN connection, location area information corresponding to the target PDN connection, and a current location of the user equipment, and may release the target PDN connection when the user equipment determines that a first condition is met. The target PDN connection can be any one or more of a plurality of PDN connections maintained by the user equipment. The first condition may include the service transmission status of the target PDN connection indicates that service transmission has stopped, and a location area indicated by the location area information corresponding to the target PDN connection does not include the current location of the user equipment.

Abstract: This application discloses a path processing method and apparatus, and a terminal. In the path processing method, user equipment may determine, based on connection parameter information corresponding to at least one existing packet data network (PDN) connection, whether a target PDN connection satisfying a target connection condition exists in the at least one existing PDN connection. When the target PDN connection satisfying the target connection condition exists, the user equipment may transmit a service packet by using the target PDN connection. When the target PDN connection satisfying the target connection condition does not exist, the user equipment may initiate establishment of the target PDN connection, to transmit a service packet by using the established target PDN connection. As can be learned, when transmitting the service packet, the user equipment may transmit the service packet by using the target PDN connection satisfying the target connection condition.
