Abstract: Embodiments of the present disclosure provide a monitoring report generation method where the method includes: receiving a monitoring parameter broadcast by a base station; monitoring energy of each discovery resource in a resource pool within a discovery time domain; determining a busy resource and an idle resource; and generating a monitoring report when a proportion of the busy resource or the idle resource in a predetermined quantity of consecutive discovery time domains meets a reporting condition corresponding to the busy resource or the idle resource, and sending the monitoring report to the base station. This resolves a problem in the related technology that: because D2D user equipment cannot accurately obtain a quantity of resource collision times in a cell, the base station cannot accurately learn a resource status in the cell, and it is ensured that the base station can accurately learn the resource status in the cell.

Abstract: The present invention discloses a D2D synchronization method, user equipment, and a serving cell. The method includes: acquiring, by user equipment, synchronization control information of a serving cell; acquiring an identity of a first synchronization signal sent by a first synchronization source that is obtained through searching on a second transmission carrier frequency, and signal quality of the first synchronization source; determining, according to the identity of the first synchronization signal, the signal quality of the first synchronization source, and the synchronization control information, whether to start to send a synchronization signal; sending, by the user equipment, a second synchronization signal on a third transmission carrier frequency whose frequency is different from a frequency of a carrier frequency of the serving cell, so that a problem of synchronization between different user equipments in a multi-carrier frequency transmission scenario can be resolved.

Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.

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.
