METHOD FOR INTER-CELL HANDOVER, BASE STATION, AND SYSTEM
First Claim
1. A method for inter-cell handover, comprising:
- sending a handover command to a user equipment by using a source cell handover bandwidth to instruct the user equipment to hand over from a source base station to a target base station; and
when the user equipment exchanges handover signaling with the target base station by using a target cell handover bandwidth, performing interference coordination on the target cell handover bandwidth to reduce interference on the user equipment.

Abstract
A method for inter-cell handover, base station, and system, relate to the field of communications technologies, for solving a problem that when a user equipment performs inter-cell handover, the handover success rate is low due to relatively large neighboring cell interference. The method for inter-cell handover includes: sending a handover command to the user equipment by using a source cell handover bandwidth to instruct the user equipment to hand over from a source base station to a target base station; and when the user equipment exchanges handover signaling with the target base station by using a target cell handover bandwidth, performing interference coordination on the target cell handover bandwidth to reduce interference on the user equipment. The present invention is applicable to the field of communications, and used for performing the inter-cell handover on a user equipment at a cell edge.

13. A base station, comprising:
-
a second processing module, configured to perform interference coordination on a source cell handover bandwidth when a user equipment exchanges handover signaling with a source base station; a third processing module, configured to instruct, in the case that the user equipment completes the handover signaling exchange between the user equipment and the source base station, the base station to stop the interference coordination on the source cell handover bandwidth; and a handover module, configured to exchange handover signaling with the user equipment by using a target cell handover bandwidth to complete handover of the user equipment from the source base station to the base station. - View Dependent Claims (14, 15, 16, 17)
