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: A data packet processing method and apparatus is disclosed. According to the method, a storage apparatus disposed on a network side stores a correspondence between an identifier and data flow characteristic information. When configuring a policy for a data packet including a first identifier, a network-side device requests the storage apparatus for data flow characteristic information corresponding to the first identifier. A PCEF receives a data packet that is sent by UE, matches the data packet against the data flow characteristic information, and when the data packet matches the data flow characteristic information, executes a policy on the data packet according to policy information corresponding to the first identifier. According to the method provided in embodiments of the present disclosure, transmitting a considerable amount of data flow characteristic information on an interface of an SCEF is avoided, and load on the SCEF is relieved.

Abstract: This application discloses a communication method and apparatus, to improve transmission efficiency of a control plane message of a terminal according to a control and provisioning of wireless access points protocol. In this application, a control request message of a terminal may be transmitted between a first communication apparatus and a second communication apparatus through a target channel. Because the target channel supports concurrency of a plurality of messages, transmission efficiency of the control request message of the terminal can be improved.

Abstract: Embodiments of this application provide a gateway handover method, a gateway reselection method, and a communications apparatus. The method includes: A source gateway determines to perform gateway handover on a terminal device; determines a target gateway that is to be used to serve the terminal device; and hands over the terminal device from the source gateway to the target gateway. According to the gateway handover method, the gateway reselection method, and the communications apparatus provided in the embodiments of this application, in a non-3GPP network architecture, when gateway handover needs to be performed on the terminal device, the source gateway of the terminal device or the terminal device may hand over the terminal device from the source gateway of the terminal device to the target gateway, to implement gateway handover in the non-3GPP network architecture.

Abstract: This application discloses a method and an apparatus for obtaining an identifier of a terminal device. The method is performed by a gateway node and includes: receiving a first message sent by a terminal device, and sending a second message to a control plane node, where both the first message and the second message carry a temporary identifier of the terminal device; receiving a third message sent by the control plane node, where the third message is sent by the control plane node when the control plane node cannot obtain a permanent identifier of the terminal device; sending a fourth message to the terminal device based on the third message; receiving a fifth message sent by the terminal device, where the fifth message carries the permanent identifier of the terminal device; and sending the permanent identifier to the control plane node based on the fifth message.
