Abstract:
A cell handover method and apparatus, and a device. The cell handover method includes: receiving, by user equipment (UE), a handover command sent by a source cell, where the handover command comprises indication information of an uplink scheduling resource indication UL grant indication information of a UL grant of a target cell; determining, by the UE based on the UL grant the indication information of the UL grant, the UL grant of the target cell; and sending, by the UE based on the UL grant, uplink data to the target cell, where the uplink data includes at least one of the following: a handover complete message, a buffer status report, or service data. Embodiments provide a cell handover method and apparatus, and a device, so as to reduce a delay time in a cell handover procedure.

Claim (Index 3):
The method of  claim 2 , wherein the TA indication information comprises the TA used by the user terminal in the target cell or the TA indication information comprises first indication information indicating that a TA of the target cell is the same as a TA of the source cell, and wherein determining the TA used by the user terminal in the target cell comprises:\n using, by the user terminal based on the first indication information, a TA used by the user terminal in the source cell as the TA used in the target cell; or the TA indication information comprises the TA of the source cell, second indication information instructing to calculate the TA of the target cell based on the TA of the source cell, and downlink signal sending moment information of the source cell and the target cell; the determining, by the user terminal based on the TA indication information, a TA used by the user terminal in the target cell comprises: separately detecting, by the user terminal based on the second indication information, a downlink signal arrival time of the source cell and a downlink signal arrival time of the target cell; determining, by the user terminal based on the downlink signal arrival time of the source cell, the downlink signal arrival time of the target cell, and the downlink signal sending moment information of the source cell and the target cell, a downlink synchronization delay difference between the source cell and the target cell; and determining, by the user terminal based on the downlink synchronization delay difference and the TA of the source cell, the TA used by the user terminal in the target cell.
