  • Publication number: 20210105679
    Abstract: Embodiments of this application provide a communications method and apparatus. The method includes: determining a target cell based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition; and sending a measurement result of the target cell to a base station. Based on the foregoing technical solution, the terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.

  • Publication number: 20210092661
    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.

  • Patent number: 10863569
    Abstract: Embodiments of the present disclosure provide a data transmission method, user equipment, and an access network device. UE transmits air interface data to an access network device by using a serving cell set including at least two core serving cells that can independently serve the UE to transmit data, and initiates an RRC connection re-establishment process to the access network device only when detecting that all core serving cells in the serving cell set are unavailable. Data transmission is performed by using an available serving cell to the greatest extent. In other words, data transmission can be performed by using any available core serving cell, to reduce the dependence of data transmission between serving cells and minimize possibility of data transmission interruption, thereby improving data transmission robustness.
