Abstract: The present disclosure relates to positioning request processing methods, devices, and systems In one example method, a mobility management network element receives a request message, and sends a first message to a location management network element based on the request message, where the first message is used to trigger the location management network element to obtain location information of a first terminal device through user plane positioning. After receiving the first message, the location management network element sends a second message to the first terminal device based on the first message by using a protocol data unit (PDU) session of the first terminal device, where the second message indicates the first terminal device to report positioning data.

Abstract: This application provides a slice information update method and an apparatus. The method includes: when determining that a network slice that was once not supported by a PLMN is updated to be supported by the PLMN, sending, by a network slice selection network element, a notification message to a communications network element, where the notification message is used to indicate that the PLMN supports the network slice; and notifying, by the communications network element, a terminal that failed to request the network slice and has subscribed to the network slice that the PLMN currently supports the network slice. In this way, the corresponding terminal learns that the PLMN currently supports the network slice.

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.
