Abstract: A communication method and apparatus, to help improve efficiency of identifying a fake base station. The method includes: A terminal device receives configuration information sent by a network device, and then simultaneously measures, based on the configuration information, a channel state information-reference signal CSI-RS and a synchronization signal block SSB that are sent by a cell. When determining that a measurement result of the CSI-RS and a measurement result of the SSB of the cell satisfy a preset condition, the terminal device reports a measurement report to the network device, where the measurement report includes identification information of the cell, so that the network device identifies a fake base station.

Abstract: Example handover methods and apparatus are described. One example method includes generating a handover request message or a handover requirement message by a source radio access network (RAN) device. The handover request message includes a first mapping relationship between downlink transmission of a quality of service (QoS) flow and a data radio bearer (DRB) and a second mapping relationship between uplink transmission of the QoS flow and a DRB that are configured by the source RAN device for a terminal device, where the two mapping relationships are different. The source RAN device sends the handover request message to a target RAN device, and forwards data of the terminal device on the source RAN device to the target RAN device in a process in which the terminal device is handed over from the source RAN device to the target RAN device.

Abstract: A communications method and apparatus, a system, and a storage medium, to provide a method to support handover of user equipment between network side devices or networks with different bearer support capabilities is provided. The method includes: sending a first message, where the first message includes information of N bearers to be handed over, and when N is greater than M, a first information element in the first message includes information of M bearers in the N bearers, and a second information element in the first message includes information of N−M bearers other than the M bearers in the N bearers, where M is a maximum quantity of bearers supported by the first information element, and the second information element is an information element unidentifiable by a target network element of the handover.
