协作多基站组网环境下的主从基站选择与切换方法

Selection and switching method of master and slave base stations under cooperation multiple-base station networking environment

Abstract

本发明涉及一种协作多基站组网环境下的主从基站选择与切换方法,包括1)判断是否存在切换触发条件,若为是,执行步骤2);2)并判断是切换需求一还是切换需求二,若为切换需求一,执行步骤3),若为切换需求二,执行步骤6);3)对活动基站簇成员按信号质量降序排列;4)候补基站簇成员按信号质量降序排列,若候补基站簇的基站数大于活动基站簇的基站数n,只需选出信号最强的n个基站;5)对候补基站簇中的有效基站的信号强度进行一一判断来更新活动基站簇等步骤。与现有技术相比,本发明具有适用范围广、灵活性好、最大程度地提高频谱利用率和功率利用率等优点。
The invention relates to a selection and switching method of master and slave base stations under a cooperation multiple-base station networking environment. The method comprises the following steps: step (1), determining whether there is a switching trigger condition; if so, executing step (2); step (2), determining whether the trigger condition is a switching demand one or a switching demand two; if the trigger condition is the switching demand one, executing a step (3); if the trigger condition is the switching demand two, executing a step (6); step (3), according to signal quality, arranging members of a mobile base station cluster in a descending order; step (4), according to signal quality, arranging members of a candidate base station cluster in a descending order; if a base station number of the candidate base station cluster is larger than a base station number n of the mobile base station cluster, only selecting n base stations with strongest signals; step (5), determining signal intensities of effective base stations in the candidate base station cluster one by one so as to update the mobile base station cluster. Compared with the prior at, technology employed in the invention enables the method to have the following advantages: wide application scope, good flexibility; and maximum improvement on a frequency spectrum utilization rate and a power utilization rate.
