Abstract
Embodiments can provide an inter-cell handover method and a controller to shorten a handover delay. For achieving such, a target cell can be determined by a first controller of a source cell. The first controller can send a pre-handover request to a second controller, which may be a controller of the target cell. The pre-handover request can be configured for instructing the second controller to allocate a first resource for a cell handover to a terminal device. The first controller can send a handover command to the terminal device when the first controller determines that the terminal device meets a handover condition. The handover command can be configured for instructing the terminal device to be handed over from the source cell to the target cell based on the first resource.
