Abstract: This application provides a paging method and an apparatus. In the paging method, a first core network device sends first signaling to a first device, indicating to the first device to page a terminal device. The first device may send second signaling, where the second signaling may indicate information about a first flag. The information about the first flag indicates that a type of a flag of a to-be-paged terminal device is a first type and/or a state of the flag is a first state, to determine the to-be-paged terminal device. In this way, a mechanism for paging the terminal device is provided, and there is no need to determine which terminal device is to be paged. This helps simplify the process of paging the terminal device.

Abstract: Examples of message transmission methods and apparatus are described. In one example, a message transmission method includes that a first network device receives a first message from a terminal device, where the first message includes a resume cause value and an integrity check code. The integrity check code is generated based on the resume cause value, the terminal device is in an inactive state, and the resume cause value is a resume cause indicated by a higher layer or a radio resource control (RRC) layer. The first network device sends a second message to a second network device, where the second message includes the resume cause value and the integrity check code. The second network device is a network device that stores a context of the terminal device.

Abstract: Embodiments of this application disclose a communication method and an apparatus, and relate to the communication field, to support a terminal device in performing beam failure detection in a common beam scenario. The method includes: A terminal device receives a first transmission configuration indicator (TCI) from an access network device, where the TCI may indicate a common beam. For example, the first TCI includes information about a first uplink reference signal and/or information about a first downlink reference signal, a spatial transmission filter corresponding to the first uplink reference signal is used for sending a plurality of uplink channels, and the first downlink reference signal and demodulation reference signals DMRSs of a plurality of downlink channels meet a quasi co-location QCL relationship.

Abstract: Embodiments of the present invention provide a communication method and apparatus. A network device determines, based on first capability information, a bandwidth part supported by a first terminal device, and sends a first paging message on a target bandwidth part, where the bandwidth part is used to carry paging or another message. The target bandwidth part matches the bandwidth part supported by the first terminal device. Therefore, compared with attempting to send the first paging message by the network device on a plurality of bandwidth parts, sending the first paging message on the target bandwidth part can effectively reduce a quantity of times of unnecessary paging sending by the network device, so as to reduce a quantity of wasted paging resources. This can effectively reduce a quantity of times of unnecessary listening of the first terminal device, reduce energy consumption of the terminal device, and improve paging efficiency.

Abstract: A communications method and a communications apparatus. For a radio bearer that carries a multicast service, a downlink user plane tunnel is established between a first access network node and a second access network node. A data packet of the multicast service is transmitted through the downlink user plane tunnel to enable the multicast service to be transmitted in a CU-DU architecture. A unicast tunnel is also established to transmit a data packet of the multicast service that is sent in a unicast mode. In this way, the first access network node is able to transmit the data packet of the multicast service to the second access network node on the unicast tunnel in the unicast mode.
