Abstract: Embodiments of this application provide example communication methods and example devices. One example method includes sending, by a first access network device, a system information block to a terminal device, where the system information block includes first information indicating that a cell served by the first access network device supports non-public network (NPN) onboarding, where the first information includes second information indicating a supported onboarding NPN, and the second information includes at least one of information about an identifier of the supported onboarding NPN or first indication information, where the first indication information indicates a support of onboarding. The first access network device can then receive a radio resource control (RRC) setup complete message from the terminal device, where the RRC setup complete message indicates that the terminal device requests NPN onboarding.

Abstract: A synchronization signal/broadcast signal block broadcast method and an apparatus are disclosed. The method includes: A first access network device RAN 1 determines to request a second access network device RAN 2 to perform resource allocation for a terminal; and the RAN 1 sends, to the RAN 2, a first message used to indicate the RAN 2 to broadcast a synchronization signal/physical broadcast channel block SSB. Accordingly, the RAN 2 starts to broadcast the SSB. The first message further includes a broadcast periodicity for the SSB. The broadcast periodicity is further sent by the RAN 1 to the terminal. The RAN 2 stops, based on a specific situation, broadcasting the SSB.

Abstract: The present disclosure relates to data transmission methods and apparatus to implement quality of service (QoS) flow-based data transmission in an architecture in which a central unit-control plane (CU-CP) and a central unit-user plane (CU-UP) are separated from each other. In one example method, when receiving data of a QoS flow, the CU-UP may send a QoS flow identity (ID) and a protocol data unit (PDU) session ID that are of the data of the QoS flow to the CU-CP, where a PDU session corresponding to the PDU session ID includes the data of the QoS flow.
