Abstract: When triggering a handover request, a source network device requests a measurement indication from a target access network device using the handover request, where the measurement indication indicates the terminal device to measure a channel state of a target cell. In this way, the source network device sends the measurement indication to the terminal device using an RRC reconfiguration message. Then, the terminal device measures the specified channel state of the target cell based on the measurement indication, to obtain a measurement result, and then determines, depending on whether the measurement result meets a handover condition, whether to perform cell handover.

Abstract: Examples in this application provide a communication method and a communications apparatus. One example communication method includes determining to deactivate or activate a first synchronization signal and physical broadcast channel block (SSB), and sending a first request message to a second network device. Specifically, the first request message carries first indication information for indicating the first SSB, and when the first SSB is an SSB in the first network device, the first request message requests the second network device to update a state of the first SSB, and the second network device maintains information about at least one SSB in the first network device, or when an active first SSB is an SSB in the second network device, the first request message requests the second network device to activate the first SSB, and the first network device maintains information about at least one SSB in the second network device.

Abstract: The disclosure provides data transmission methods and apparatuses. One example method includes when the terminal device needs to perform the cross-network movement, the terminal device sends a message to a network element of a network accessed by the terminal device, to notify that the terminal device is to perform the cross-network movement from a source network to a target network. Therefore, during the movement of the terminal device, a network side pauses transmission of user plane data of the terminal device, and buffers data that is not sent before the terminal device performs the cross-network movement. After accessing the target network, the network side sends the buffered data to the terminal device.
