Abstract: Example communication methods and apparatus are described. One example method includes receiving first information from a first device, where the first information indicates N moments and location information of the first device at the N moments. The first device obtains second information, where the second information indicates a correspondence between the N moments and M area identifiers, or the second information indicates a correspondence between N locations and M area identifiers. According to the foregoing technical solution, the first device sends the location information of the first device at the N moments, so that the M area identifiers corresponding to the first device at the N moments or the M area identifiers corresponding to N pieces of location information can be obtained.

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: This application provides a paging method and apparatus. The method includes: A first device receives a first paging message, where the first paging message includes a first list, and the first list includes an area identifier of at least one cell. The first device determines a first cell, where an area identifier of the first cell at a first moment is different from an area identifier of the first cell at a second moment, the first moment is a current moment, and the second moment is earlier than the first moment. When the area identifier of the first cell at the first moment does not belong to the first list, the first device stops paging a terminal device in the first cell. According to the foregoing technical solutions, the first device may effectively page the terminal device, to reduce signaling overheads of the first device, and save power.

Abstract: This application provides a non-terrestrial network (non-terrestrial network, NTN) communication method and an apparatus, to resolve the following problem: When performing a delay-sensitive communication service, UE may select a cell covered by a satellite since the UE cannot distinguish between a cell covered by a terrestrial base station and the cell covered by the satellite. The method includes: A first network device determines cell type information of a cell covered by a second network device, where the cell type information indicates that the cell is a terrestrial network communication cell or a non-terrestrial network communication cell; and the first network device sends the cell type information to a third network device.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: determining, based on area configuration information of a first cell of a network device and location information of a terminal device, a first sub-area corresponding to the terminal device, where the area configuration information indicates information about a plurality of sub-areas corresponding to the first cell, and the plurality of sub-areas include the first sub-area; and obtaining satellite ephemeris information corresponding to the first sub-area. In the foregoing solution, the sub-area is introduced, and the terminal device only needs to obtain the satellite ephemeris information corresponding to the sub-area in which the terminal device is located. This reduces an amount of satellite ephemeris information obtained by the terminal device, and therefore can reduce overheads of the terminal device.

Abstract: A communication method and apparatus resolves a problem that a resource usage status reported by a network device is inaccurate. The method includes: a first network device receives resource status information from a second network device, where the resource status information includes LBT-related resource information; and the first network device determines a resource usage status of the second network device based on the resource status information. In the foregoing manner, the first network device may determine a resource that is to be released by the second network device, a resource that may be occupied, and the like. In this way, the first network device may perform conversion on the resource usage status of the second network device, to obtain an accurate resource usage status, and in particular, have more accurate estimation on an estimated future resource usage status.

Abstract: A report transmission method includes determining a quantity of target reports and, in response to the quantity of target reports being greater than or equal to a first quantity, sending a first report to a first network device. The first report includes one or more target reports. A type of the target report is a first type that includes one or more of an advance measurement report, a logged minimization of drive tests report, an accessibility failure report, a random access report, a radio link failure report, a mobility history report, or a radio link failure-like report. The radio link failure-like report is for logging a first event and/or a second event. The first event is when a quantity of data retransmissions of a terminal device is greater than or equal to a first preset quantity of times and less than a second preset quantity of times.
