WCDMA网络规划中切换问题的研究

Research on Handover in Network Planning of WCDMA

主要针对WCDMA网络规划中切换问题进行研究和分析。首先从移动通信系统切换的概念和功能入手,介绍常见的几种切换方式,并对WCDMA系统中的切换进行分类。然后介绍了切换流程以及切换过程所包含的测量控制、切换判决和切换执行等各个步骤。最后对切换带来的切换比例和开销问题进行了仿真分析,并给出了WCDMA规划中合理的切换比例和相关参数的设置。

This paper analyzes and studies the handover in network planning of WCDMA. Firstit introcuces several common handover modes based on the conception and function of mobile communication system handover, and classifies the handover in WCDMA. Second, it presents the handover flow and all the handover steps including survey control, handover judgment, and handover execution. Finally, it simulates the handover proportion and overhead by handnver.Reasonable handover proportion and parameter setting are given in the WCDMA planning.
