Abstract: A communication method and apparatus are provided. The method includes: A source network device generates and sends a first message, where the first message is for handing over a terminal device from the source network device to a target network device, the first message includes first indication information, and the first indication information indicates to perform a random access-free process and/or a handover complete message-free process in a handover process. In this way, if cell jump occurs in a source cell, the terminal device may not perform a random access process and/or not send a handover complete message in a process of handover from the source cell to a target cell. This avoids uplink congestion of the target cell caused by simultaneous handover of a plurality of UEs to the target cell, effectively reduces signaling overheads, and improves network performance of a target base station.

Abstract: A communication method and an apparatus. The method includes: a terminal device receives measurement configuration information from a first network device, where the measurement configuration information indicates the terminal device to measure a first cell. The terminal device sends a measurement result to a second network device, where the measurement result is obtained by the terminal device by measuring the first cell based on the measurement configuration information, and the measurement result indicates that the terminal device obtains a signal of the first cell through measurement or does not obtain a signal of the first cell through measurement. Based on the indication, of the measurement result, that the terminal device obtains the signal of the first cell through measurement or does not obtain the signal of the first cell through measurement, whether coverage of the first cell needs to be corrected may be further determined.

Abstract: This disclosure provides communication methods, communication apparatuses, and communication systems. One example method includes: A terminal device supporting a first subscriber identity and a second subscriber identity determines to deregister the first subscriber identity from a first network. Then, the terminal device sends a deregistration request message to an access network device by using the second subscriber identity, where the deregistration request message is used to request to deregister the first subscriber identity form the first network, and the deregistration request message carries an identifier of the first subscriber identity.

Abstract: In a communication method, a first network node sends a first message to a second network node, where the first message includes first configuration information. The first network node receives a second message from the second network node, where the second message includes second configuration information determined based on the first message. The first network node includes at least one of a packet data convergence protocol layer, a service data adaptation protocol layer, or a radio resource control protocol layer. The second network node includes at least one of a radio link control protocol layer, a media access control layer, or a physical layer.

Abstract: Embodiments of this application provide a communication method and a communication apparatus. The method includes: A terminal device determines that a connection establishment failure between the terminal device and a first cell occurs, records first connection establishment failure information, and starts a timer; the terminal device determines, depending on whether the timer runs, a manner of processing connection establishment failure information; and the terminal device sends a connection establishment failure report, where the connection establishment failure report indicates that the connection establishment failure occurs between the terminal device and the first cell. In this way, memory usage and power consumption of the terminal device can be reduced.

Abstract: A communication method for a terminal device includes receiving a conditional handover (CHO) command from a source network device. The communication method also includes selecting, by the terminal device, a cell in response to a radio link failure (RLF) in a source cell before the terminal device determines a target cell. The target cell is determined according to the CHO command. The communication method additionally includes sending first information to a network device. The first information includes a first parameter. The first parameter is related to a CHO failure caused by the RLF in the source cell.

Abstract: A communication method and apparatus are provided, where the method includes: A first network device generates and sends a paging message to a second network device. The paging message is used to page a terminal device, the paging message includes first indication information, and the first indication information indicates that a paging range includes a non-terrestrial network
NTN cell and/or a terrestrial network TN cell. By applying the foregoing technical solution, the network device may determine an appropriate paging area based on a type of the terminal device or capability information of the terminal device, to avoid sending the paging message in an area that is not supported by the terminal device, so that overheads of paging signaling are effectively reduced.-
