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: The present disclosure relates to connection reestablishment methods and apparatus. In one example method, when a handover fails, a terminal reverts back to a source configuration, and obtains a selected cell. The terminal sends a connection reestablishment request to a selected radio access network device. The terminal receives a first message from the selected radio access network device, where the first message includes indication information used to indicate to derive an access network key based on a core network key. The terminal obtains a first core network key based on the indication information, and derives a first access network key based on the first core network key. The terminal communicates with the selected radio access network device by using the first access network key.
