Abstract: This application discloses a cell camping method and an apparatus. The method includes: After a terminal device camps on a first cell, a network device may send a first message to the terminal device, where the first message includes information about a second cell, the first cell corresponds to a first CC, and the second cell corresponds to a second CC; after receiving the first message, the terminal device sends a second message to the network device, where the second message may indicate the first cell and/or the second cell, or the second message may include measurement information of the first cell and/or the second cell; and the network device may determine, based on the second message, that the terminal device camps on the first cell or the second cell. This ensures network load balancing between different cells.

Abstract: This application discloses a clock synchronization method and a related apparatus in a distributed system. The distributed system includes a plurality of nodes, and the plurality of nodes include a master node and a plurality of slave nodes. The master node obtains a plurality of local clock offsets, where each of the plurality of local clock offsets indicates a clock offset between two nodes in the distributed system. The master node determines a global clock offset of a target slave node relative to the master node based on the plurality of local clock offsets, and sends the global clock offset to the target slave node. The target slave node obtains a clock reference value of a local clock, and then performs clock synchronization based on the clock reference value and the global clock offset.

Abstract: Embodiments of this application provide a node handover method and an apparatus. A source secondary node receives first handover information and determines to perform an uninterrupted node handover. The source secondary node performs, in a process of the uninterrupted node handover, first processing on first data received by the source secondary node, to obtain second data, and sends the second data to a terminal device. The source secondary node performs second processing on the first data to obtain third data in the process of the uninterrupted node handover, and sends fourth data to the terminal device via a target secondary node. According to some embodiments provided in this application, a communication delay of the terminal device can be reduced, and user experience of the terminal device can be improved.
