Abstract: The present disclosure relates to time synchronization methods and apparatus. In one example method, a terminal receives a system information block (SIB) sent by a distributed unit (DU), where the SIB is generated by the DU, the SIB includes time information, and the time information indicates a moment corresponding to a boundary of a system frame number (SFN) at which an end boundary of a system information (SI) window for sending the SIB is located, or indicates a moment corresponding to a boundary of an SFN immediately after an end boundary of an SI window for sending the SIB. The UE processes the time information to obtain a time reference.

Abstract: Example communication methods and apparatus are described. One example method includes sending a first handover request by a source base station to a core network device, where the first handover request is used to request to hand over a current session of a terminal from the source base station to any one of at least one base station, and the first handover request includes information about the at least one base station. The source base station receives a first handover response message from the core network device, where the first handover response message includes indication information, and the indication information is used to indicate whether a first base station of the at least one base station supports a network slice corresponding to the current session of the terminal device.

Abstract: This application provides a communication method, an apparatus, and a system, to improve communication efficiency. One method includes: sending, by an access network node to a terminal device, indication information indicating to transmit a quality of service (QoS) flow by using a bearer, wherein a protocol stack corresponding to the bearer supports transmission of the QoS flow through a first path, wherein the first path passes through one of (1) a service data adaptation protocol (SDAP) layer of a master node and a protocol layer below an SDAP layer of a secondary node, or (2) an SDAP layer of the secondary node and a protocol layer below an SDAP layer of the master node; and transmitting, by the access network node, the QoS flow by using the first bearer.

Abstract: This application provides a communication method, a network device, and a terminal. The communication method includes: obtaining, by a first network device, a first AMBR of a PDU session, where the first AMBR is an AMBR of a flow that is served by a second network device in the PDU session, the first network device is a master node serving a terminal, and the second network device is a secondary node serving the terminal; sending, by the first network device, first information to the second network device, where the first information includes the first AMBR, so that the second network device provides, based on the first AMBR, the PDU session service for the terminal. The communication method, the network device, and the terminal provided in this application help ensure a session-level aggregate maximum rate requirement in a dual connectivity scenario.

Abstract: This application provides a network overload control method and an apparatus. The method includes: determining, by a core network device, to perform overload control for at least one network slice; sending, by the core network device, a first message to a radio access network device, where the first message includes an overload response to at least one piece of single network slice selection assistance information or at least one network slice category; and performing, by the radio access network device, an overload action on a radio resource control request of the at least one network slice. According to the network overload control method in this application, a network effectively performs overload control for any network slice.

Abstract: Embodiments of the present invention disclose a communication method, an access network device, and a core network device. The method includes: sending, by a source access network device, to a core network device a handover message for a handover of one or more sessions of a terminal device from the source access network device to a target access network device, wherein the handover message comprises information about the target access network device and identifier information of the one or more sessions; and sending, by the core network device, a response message of the handover message to the source access network device, wherein the response message of the handover message comprises indication information indicating a reason that a session of the one or more sessions is not accepted, wherein the reason is associated with a slice corresponding to the session.
