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 provide for a communication method and a related communication apparatus. A second access network device receives a first message from a first access network device, where the first message indicates whether a first state of a multicast broadcast service (MBS) session is activated or deactivated. The second access network device sends a first acknowledgment message corresponding to the first message to the first access network device. In this solution, the first message indicates the first state of the MBS session, and the second access network device may determine, based on the first state, whether to request a core network to establish a user plane (UP) tunnel. If the first state of the MBS session is activated, the second access network device may be triggered to newly establish a UP tunnel, to ensure a normal transmission of the MBS in a handover process.

Abstract: Embodiments of this application disclose a communication method and a related communication apparatus. In a dual connectivity scenario, user equipment (UE) establishes a dual connection to a master radio access network node (MN) and a secondary radio access network node (SN). When the MN requests the SN to provide a multicast broadcast service (MBS) for the UE of the MN, the MN sends a first request to the SN, where the first request includes a first identifier corresponding to the MBS. After receiving the first request, the SN sends a first response to the MN, where the first response indicates that the SN agrees to provide the MBS service for the UE. In this way, MBS service data is sent to the UE through the SN in the dual connectivity scenario.
