Abstract

The embodiment of the invention provides a sector selection method in cell switch and a base station controller. The method includes: determining a first sector which is the sector in a service cell of a piece of user equipment and is also the sector the user equipment is currently in; determining adjacent sectors of the first sector and judging whether the adjacent sectors are the sectors of a target cell to which the user equipment is switched, and the target cell is the adjacent cell of the service cell; and activating the radio remote units (RRU) or radio frequency units (RFU) of at least one second sector according to the judging result so that the RRUs or RFUs of the at least one second sector send information to the user equipment and the at least one second sector is the sector of the target cell. Thus resource utilization rate is effectively improved and interferences from adjacent cells of the same frequency are reduced while receiving quality of the user equipment is ensured.

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 (Radio Remote Unit, radio remote unit) or RFU (Radio Frequency Unit, radio frequency unit). [0003] In the prior art, when the UE (User Equipment, User Equipment) is moving from the serving cell to the target cell during the movement of the multi-sector network architecture, 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 ser...
