CELL-ID技术是目前最简单的定位技术,它的原理是通过获取目标手机所在的蜂窝小区ID来确定其所在的位置,提供给定位用户。它不需要移动台提供任何定位测量信息,也无须对现网进行改动,只需要在网络侧增加简单的定位流程处理即可,因而最容易实现,目前这种定位技术已经在各移动网络中广泛使用。它的定位原理很简单:网络根据移动台当前的服务基站的位置和小区覆盖来定位移动台。若小区为全向小区,则移动台的位置是以服务基站为中心,半径为小区覆盖半径的一个圆内;若小区分扇区,则可以进一步确定移动台处于某扇区覆盖的范围内。

Swarm intelligence algorithms are based on natural behaviors. Particle swarm optimization (PSO) is a stochastic search and optimization tool. Changes in the PSO parameters, namely the inertia weight and the cognitive and social acceleration constants, affect the performance of the search process. This paper presents a novel method to dynamically change the values of these parameters during the search. Adaptive critic design (ACD) has been applied for dynamically changing the values of the PSO parameters.
