Abstract:
Disclosed are an inter-cell handover method and a controller able to shorten a handover delay. The method comprises: a first controller determining a target cell, wherein the first controller is a controller of a source cell; the first controller sending a pre-handover request to a second controller, wherein the second controller is a controller of the target cell, and the pre-handover request is used for instructing the second controller to allocate, to a terminal device, a first resource needed to perform cell handover; and when the first controller determines that the terminal device satisfies a handover condition, sending a handover instruction to the terminal device, wherein the handover instruction is used for instructing the terminal device to execute a handover from the source cell to the target cell based on the first resource.
