A method for reducing inter-cell signal interference, comprising: a sending, by a serving base station, a user identity of a served user equipment to neighboring second base station, obtaining a coordinated radio resource for scheduling only the user equipment corresponding to the user identity by coordinating with the second base station, so that the second base station avoids using the coordinated radio resource, wherein the second base station avoiding using the coordinated radio resource includes the second base station using a radio resource at the same frequency as the coordinated radio resource but at a different time from the coordinated radio resource, or the second base station using a radio resource at different frequencies from the coordinated radio resource but at the same time as the coordinated radio resource, or the second base station using the coordinated radio resource at a reduced power with respect to the serving base station; and using, by the serving base station, the coordinated radio resource to schedule the user equipment corresponding to the user identity; characterized in that after the coordinating a radio resource with the second base station, the method further comprises: sending, by the serving base station, a handover request message to the second base station; and receiving, at the serving base station, a handover request acknowledgment message returned by the second base station for the handover request message; stopping, by the serving base station, using the coordinated radio resource, after delivering a handover command to the UE; wherein using, by the serving base station, the coordinated radio resource to schedule the user equipment corresponding to the user identity comprises: using, by the serving base station, the coordinated radio resource to send a handover command message to the user equipment corresponding to the user identity; wherein a process of coordinating a radio resource with the second base station comprises: sending, by the serving base station, information on the coordinated radio resource or a radio resource identity for scheduling the user equipment to the second base station. a sending, by a serving base station, a user identity of a served user equipment to neighboring second base station, obtaining a coordinated radio resource for scheduling only the user equipment corresponding to the user identity by coordinating with the second base station, so that the second base station avoids using the coordinated radio resource, wherein the second base station avoiding using the coordinated radio resource includes the second base station using a radio resource at the same frequency as the coordinated radio resource but at a different time from the coordinated radio resource, or the second base station using a radio resource at different frequencies from the coordinated radio resource but at the same time as the coordinated radio resource, or the second base station using the coordinated radio resource at a reduced power with respect to the serving base station; and using, by the serving base station, the coordinated radio resource to schedule the user equipment corresponding to the user identity; characterized in that after the coordinating a radio resource with the second base station, the method further comprises: sending, by the serving base station, a handover request message to the second base station; and receiving, at the serving base station, a handover request acknowledgment message returned by the second base station for the handover request message; sending, by the serving base station, a handover request message to the second base station; and receiving, at the serving base station, a handover request acknowledgment message returned by the second base station for the handover request message; stopping, by the serving base station, using the coordinated radio resource, after delivering a handover command to the UE; wherein using, by the serving base station, the coordinated radio resource to schedule the user equipment corresponding to the user identity comprises: using, by the serving base station, the coordinated radio resource to send a handover command message to the user equipment corresponding to the user identity; wherein a process of coordinating a radio resource with the second base station comprises: sending, by the serving base station, information on the coordinated radio resource or a radio resource identity for scheduling the user equipment to the second base station.
