Abstract: A method for processing a time synchronization packet is provided. In an embodiment a terminal device receives a time synchronization packet of a first clock source from an external device; receives first indication information from a network device, where the first indication information instructs the terminal device to enter a time synchronization activated state of the first clock source, or the first indication information instructs the terminal device to enter a time synchronization deactivated state of the first clock source; and processes the time synchronization packet of the first clock source based on the first indication information. When a clock source is activated and deactivated, the terminal device processes a time synchronization packet of the clock source in different manners, and signaling indicates whether the clock source is activated or deactivated.

Abstract: This application provides a communication method and apparatus, to separately configure, for different terminal devices in different public land mobile networks PLMNs, different policies. The method includes: A core network element receives a registration request from a terminal device, and then sends a registration response to the terminal device based on first information and/or second information, where the registration response indicates the terminal device to set the first information. The terminal device sets the first information based on the registration response. The first information indicates a selection policy that is determined by the core network element and that is of selecting a CAG by the terminal device when the terminal device accesses a first PLMN, and the second information indicates a selection policy that is determined by the core network element and that is of selecting a CAG by the terminal device when the terminal device accesses the first PLMN.

Abstract: This application provides a resource reservation method and an apparatus. The method includes: receiving, by a node, a first message, where the first message carries a bandwidth value r1 of a resource requested to be reserved and a quantity Q1 of cycles occupied by the resource, the node maintains resource reservation states in K cycles, K is a positive integer, and Q1 is less than or equal to K; and updating, by the node, resource reservation states in Q1 of the K cycles based on the bandwidth value r1 and the quantity Q1. The node maintains the resource reservation states at a granularity of cycles. Therefore, the resource reservation states that need to be maintained by the node do not depend on a quantity of data flows processed by the node, and a performance requirement of a resource reservation for the node can be lowered.

Abstract: A cell selection method includes receiving, by an access stratum (AS) of a terminal device, first information from a non-access stratum (NAS) of the terminal device. The first information includes identity information of a first public land mobile network (PLMN) to be accessed by the terminal device. The cell selection method also includes determining, by the AS based on the first information, whether to camp on a first candidate cell. The first candidate cell supports the first PLMN. The first candidate cell satisfies a first camping condition. The first camping condition comprises a cell selection criterion and a service requirement. The service requirement is a preset threshold of a parameter reflecting signal quality of a cell.
