Abstract

Embodiments of the present invention provide a method for sector selection during cell handover and a base station controller. The method includes: determining a first sector, which is a sector in a serving cell of a user equipment and is the The sector in which the user equipment is currently located; determine the adjacent sectors of the first sector, and determine whether the adjacent sectors are sectors in the target cell to which the user equipment is switched, and the target cell is the Neighboring cells of the serving cell; activate the radio frequency remote unit RRU or radio frequency unit RFU of at least one second sector according to the judgment result, so that the RRU or RFU of the at least one second sector sends information to the user equipment , the at least one second sector is a sector in the target cell. In this way, while ensuring the reception quality of the user equipment, resource utilization can be effectively improved and interference to adjacent cells on the same frequency can be reduced.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and more specifically, relates to a method for sector selection and a base station controller during cell handover. Background technique [0002] In a multi-sector networking architecture, a cell can be composed of one or more base stations, each base station has multiple sectors, and each sector corresponds to an RRU (RadioRemoteUnit, radio remote unit) or RFU (RadioFrequencyUnit , RF unit). [0003] In the prior art, when a UE (User Equipment, User Equipment) is moving from a serving cell to a target cell in the process of moving in a multi-sector network architecture, and the target cell does not yet know which sector the UE is currently switching to, In order to ensure the receiving quality of the user equipment, the RRUs or RFUs of all sectors of the target cell will exchange information with the UE, for example, send information such as service data or cont...
