Abstract: This application provides a communication method and apparatus. The method includes: a terminal device receives conditional handover configuration information from a first network device, where the configuration information is used to configure a trigger condition of a conditional handover, and the first network device is a network device to which a serving cell currently accessed by the terminal device belongs. The terminal device determines a first target cell based on the conditional handover configuration information, where the first target cell is a cell in at least one candidate target cell that satisfies the trigger condition.

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: The present disclosure relates to communication methods and apparatus. On one example method, a terminal device obtains measurement results of N cells, where the N cells include M non-public network cells, where N is an integer greater than or equal to 1, and where M is an integer greater than or equal to 0. The terminal device determines, based on the measurement results of the N cells and measurement result offset values corresponding to H first cells in the N cells, a target cell on which the terminal device is to camp, where H is an integer greater than or equal to 1, and where H≤N.

Abstract: This application provides a communications method and device, and a computer-readable storage medium. The method includes: receiving an uplink data transmission threshold from a first network device, where the uplink data transmission threshold includes both a first transmission threshold and a second transmission threshold or includes a second transmission threshold. The first transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in a non-connected state on a first uplink carrier, and the second transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in the non-connected state on a supplementary uplink (SUL) carrier. The method further comprises determining, based on the uplink data transmission threshold and a size of a to-be-transmitted uplink data packet, to transmit, in the non-connected state, the uplink data packet on the first uplink carrier or the SUL carrier.

Abstract: This application provides a communications method and a communications apparatus, to reduce storage resources required by an access network device to store a context of a terminal device. The method includes: The access network device gathers terminal devices that have a same attribute in a group, where a context of each terminal device is divided into two parts: a common context and a dedicated context, the common context is shared by all the terminal devices in the group, and the dedicated context is a context specific to the terminal device. The access network device stores one common context for each group and stores a dedicated context of each terminal device in the group, to maintain the context of each terminal device.

Abstract: Embodiments of the present invention provide a communication method and a communications device. The method includes: sending, by a base station, a message including measurement configuration to UE, where the measurement configuration is used to request the UE to report a cell global identifier of a cell; obtaining, by the base station, a measurement report reported by the UE, where the measurement report corresponds to the measurement configuration and includes the cell global identifier of the cell and band information of the cell; and performing, by the base station, cell handover based on the band information and the cell global identifier of the cell. By means of the present invention, the base station obtains complete and accurate band information of the cell, so that the base station can perform accurate handover decision, thereby avoiding handover failure.

Abstract: The present disclosure relates to a notification method. In one example method, a first base station configures a first cell identity for a first cell. The first cell identity comprises a first identifier field and a second identifier field. A reserved bit in the second identifier field and the first identifier field identify the first base station. A remaining bit in the second identifier field identifies the first cell. The first base station notifies a second base station or a core network device of a part of the first cell identity that identifies the first base station.
