  • Patent number: 10716032
    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.

  • Publication number: 20200029207
    Abstract: Embodiments of the present disclosure relate to a data transmission method, user equipment, and a control plane node. User equipment (UE) determines a security attribute of a session of the UE; the UE sends a session establishment request message to a control plane node when the security attribute of the session of the UE does not meet a security requirement of an application. The session establishment request message is used to request to establish a session corresponding to the security requirement of the application. Embodiments of the disclosed method reduce an unnecessary signaling exchange caused by establishment of a new session in a data transmission process to facilitate meeting requirements of different services.
