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.

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: A communication control method and a related network element are provided. The communication control method includes: receiving a control request related to a user terminal that accesses a network through a first base station, and determining, based on the control request, a first service network element providing a service for the user terminal; determining a first forwarding plane network element providing a forwarding service for the user terminal; and establishing a service packet forwarding path between the first service network element and the first forwarding plane network element to transmit a service packet of the user terminal. Technical solutions in embodiments of the present invention provide an end-to-end service packet routing mechanism.
