Abstract: Methods, systems, and apparatus for clock synchronization are provided. In one aspect, a clock synchronization method includes: receiving, by a terminal and from an access network device, information about N clock domains, determining, by the terminal, M clock domains that are associated with the terminal and that are in the N clock domains, and separately performing, by the terminal, clock synchronization with clock sources of the M clock domains based on information about the M clock domains. Information about a clock domain includes first time information and a clock domain number of the clock domain. The first time information includes a time of a clock source of the clock domain when the access network device sends the information about the clock domain. The clock domain number identifies the clock domain. N is an integer greater than 1, and M is an integer greater than 1.

Abstract: A service transmission method and apparatus are provided to establish a connection between an access and mobility management function network element and a secondary base station, when a master base station is not capable of continuing to provide a service for a terminal device. In an embodiment, an access and mobility management function network element determines that a master base station is not capable of continuing to provide a service for a terminal device. The access and mobility management function network element sends a mobility management context of the terminal device to a secondary base station, where the mobility management context is used by the secondary base station to perform mobility management on the terminal device. Therefore, a signaling connection between the access and mobility management function network element and the secondary base station can be quickly established, thereby ensuring service transmission and improving user experience.

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.

Abstract: An IP address assignment method and an apparatus are provided, to resolve a problem in the prior art that a control plane network element cannot determine, in an IP address assignment process, a terminal device to which IP address information is to be assigned. In the method, after determining an identifier of a terminal device, a core network control plane network element in a mobile communications network assigns IP address information to the terminal device corresponding to the identifier of the terminal device. In this way, after assigning the IP address information, the core network control plane network element can determine a correspondence between the IP address information and the identifier of the terminal device.

Abstract: Embodiments of the present disclosure disclose a service processing method, an apparatus, and a system that relate to the field of communications technologies and are used to reduce resource waste. The method includes: controlling, by a controller, a first node to send a received packet to a processing network; and controlling, by the controller, the processing network to process the packet and then send a processed packet to a second node. The first node is a base station or a network element connected to the base station, and the second node is a routing function entity; or the first node is the routing function entity, and the second node is the base station or a network element connected to the base station. The routing function entity is an anchor point of an Internet Protocol IP address of a user.

Abstract: This application provides a satellite communication method and an apparatus. The method may include: A session management network element obtains an identifier list. The identifier list includes identification information of one or more terminal devices that access a satellite in a satellite backhaul manner. The session management network element configures a forwarding rule for a user plane network element on the satellite. The forwarding rule is used to offload, to an access network device corresponding to the terminal device, a data packet whose destination address is included in an address of the terminal device corresponding to the identifier list. Based on the foregoing solution, a terminal device that supports local switching in the satellite can perform communication through local switching in the satellite, so that a delay can be reduced and user experience can be improved.

Abstract: This application provides a communication method and apparatus. The method may include: A first session management network element determines an offloading point in a visited network based on first information, where the first information indicates that offloading is allowed in the visited network, and the first session management network element is a network element deployed in the visited network; and the first session management network element sends an offloading rule to the offloading point, where the offloading rule is for offloading a packet to the visited network. According to this application, after accessing the visited network through HR roaming, a terminal device may access a service in the visited network by using the offloading point determined by the first session management network element, to implement local offloading in the visited network.
