Abstract: Described herein are a communication method, a security node network element, and a terminal. The method includes receiving, by a security node network element, a first data packet carrying first user plane data or first control signaling from a terminal, the first data packet is transmitted via a first security connection or a second security connection, the first security connection is used to transmit the first data packet carrying the first user plane data, and the second security connection is used to transmit the first data packet carrying the first control signaling; and sending the first control signaling to a control plane (CP) function entity if the first data packet is transmitted via the second security connection.

Abstract: A method includes processing, by an information sharing network element executed by a processor, a monitoring request received from a content server to determine whether a handed-over-to network supports monitoring information included in the monitoring request. The monitoring information is associated with a terminal that is in one of a first network or a second network and is handed over to the other of the first network or the second network. The method also includes sending, by the information sharing network element, the monitoring information to a mobility management network element in a handed-over-to network based on a determination that the handed-over-to network supports the monitoring information. The monitoring information includes data associated with the terminal in a handed-over-from network.

Abstract: The present disclosure describes a network status information transfer method. In one example method, a first message, transmitted by a third-party server to a user equipment (UE), is received by the UE. The first message comprises an identifier, associated with a trusted wireless local area networks (WLAN) network (TWAN), and first indication information indicating that a packet data network gateway (PGW) is overloaded. If the UE has added the identifier associated with the TWAN to a blacklist, the identifier associated with the TWAN is deleted, by the UE, from the blacklist in response to receiving the first message.

Abstract: Embodiments of this application relate to the field of communications technologies, and provide a network connection method and an apparatus. The method carried out by a network control element includes: sending a first connection parameter to a terminal, and sending a second connection parameter to a security node, so that a network connection between the terminal and the security node is established by using the first connection parameter and the second connection parameter, where the first connection parameter is used for decrypting data encrypted by using the second connection parameter, correspondingly, the second connection parameter is used for decrypting data encrypted by using the first connection parameter, and the first connection parameter and the second connection parameter each include a security parameter used when the terminal and the security node establish the network connection.
