Abstract: This application discloses a method for a handover of a mobile station between a source base station and a target base station. The target base station receives a handover request message from the source base station. The handover request message includes quality of service (QoS) information of the mobile device, radio bearer identifier information of the source base station, and a first mapping relationship between a flow and a radio bearer of the source base station. The target base station sends a handover acknowledgement message to the source base station.

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.

Abstract: A method includes receiving a first message from a first master node. The first message includes an identifier of a first candidate primary secondary cell (PSCell) or an identifier of first configuration information of the first candidate PSCell. The first candidate PSCell is included in both a first PSCell list and a second PSCell list. Alternatively, the first message includes delta configuration information of a second candidate PSCell in the second PSCell list. The first configuration information of the first candidate PSCell includes an addition/change condition and a configuration of the first candidate PSCell. The first PSCell list includes one or more candidate PSCells configured by the first master node for a terminal. The second PSCell list includes one or more candidate PSCells configured by a second master node for the terminal. The method also includes adding a target PSCell or changing from an original PSCell to the target PSCell.

Abstract: A communication method and an apparatus are provided in embodiments of this application. When a cell served by a DU of an access network device and a neighboring cell use different timing, the DU may obtain timing configurations of a first cell and a second cell, or a RACH configuration that is of a second cell and that is based on timing of a first cell. When the method is applied to a RACH optimization scenario, the DU may determine, at same timing, RACH configurations of the two cells based on the foregoing obtained information, to accurately identify whether a RACH configuration conflict occurs between the cell and the neighboring cell, optimize the RACH configuration of the cell when the conflict occurs, and ensure a success rate and an access latency of random access performed by a terminal device.

Abstract: A handover method and a communication apparatus. A terminal device receives a first message, where the first message includes information about N candidate cells, the N candidate cells include N1 candidate cells and N2 candidate cells, the N1 candidate cells include a cell for which no conditional handover CHO execution condition information is configured, the N2 candidate cells include a cell for which the CHO execution condition information is configured, N and N2 are integers greater than 1 or equal to 1, and N1 is an integer greater than 0 or equal to 0. In a process of attempting to hand over from the source cell to the target cell, the terminal device maintains an RRC connection and/or data transmission with the source cell. Therefore, handover reliability is improved, a handover latency is reduced, and overall system performance is improved.
