Abstract: This application provides a cell measurement method and a communications apparatus. The method may include: A terminal device measures a serving cell, where the serving cell is a satellite cell. The terminal device determines whether the serving cell meets a preset condition. For example, compared with a last measurement result, whether quality of the serving cell becomes better or remains unchanged, or deteriorates but a deterioration magnitude is relatively small. When the serving cell meets the preset condition, the terminal device does not measure or stops measuring the serving cell within a first duration. The terminal device may measure the serving cell after the first duration expires.

Abstract: This application provides a cell reselection method and an apparatus. The method includes: measuring a target frequency to obtain at least two cells that meet a first condition; determining remaining coverage time of the at least two cells; and determining a target cell based on the remaining coverage time of the at least two cells. According to this solution, the target cell (that is, a reselected cell) is determined based on the remaining coverage time during reselection.

Abstract: The disclosure provides communication methods and apparatuses. One example method including a first access network device sends a first message to a terminal device and a second message to a core network device. The first message is used to indicate the terminal device to enter an inactive state. The second message carries context information and a first security verification parameter of the terminal device, and the first security verification parameter is used to perform security verification on the terminal device. The first access network device receives a third message from a second access network device, where the third message is used to request the context information of the terminal device. The first access network device sends a fourth message to the second access network device, where the fourth message is used to indicate the first access network device not to provide the second access network device with the context information.

Abstract: A communications method includes a terminal device receives broadcast information sent by a network device, where the broadcast information includes first information indicating N configuration parameters and a plurality of pieces of second information indicating Mi configuration parameters. Then, the terminal device determines configuration information of an ith reference signal based on some or all of the configuration parameters indicated by the first information and the Mi configuration parameters indicated by the ith piece of second information, where the configuration information of the ith reference signal includes Qi configuration parameters, and Qi is greater than or equal to N, and Qi is greater than or equal to Mi. The method reduces signaling overheads of the broadcast information.
