关于提升掉话指标的经验

Experience on the Call Drop Enhancing

掉话率在移动通信网中是一项非常重要的指标,是日常优化的一个永恒的主题,掉话率的高低在一定程度上体现了移动网通信质量的优劣。话音掉话主要包括无线网络掉话、Abis接口掉话、A接口掉话及其他原因造成的掉话,其中约有一半以上的话音掉话是无线网络的掉话。影响掉话的因素也多种多样,如小区覆盖不合理、频率规划有问题、干扰、基站软硬件故障、传输质量不好、天馈线系统问题等。因此,需要我们在实践中不断的探索,不断的创新,以达到提升指标的目的。近期我们以掉话为专题,再次进行提升掉话指标的优化工作,我根据现网实际情况,从掉话分类属性参数调整、邻区优化、BSRXMIN及上行功控优化四个方面入手,对覆盖廊坊市的LFBS15进行专项优化工作,现将优化经验总结如下,当然掉话指标的优化是个循序渐进的过程,需要结合网络现状对已有的优化方法有选择地应用,这样,才能不断丰富网络优化的经验,提升无线网络的各项指标。

Call drop index is a very important indicator in the mobile communication network. It is an eternal theme in the daily optimization. And it reflects the quality of wireless network. Voice call dropping includes wireless network call dropping,Abisinterface call dropping, A-interface call dropping, and some other causes. Wireless network call dropping takes the half part. A variety of factors affect the call dropping, such as the unreasonable cell coverage, frequency planning problems, interference, base station hardware and software failures, bad transmission quality, antenna system problems, and so on. Therefore, we need to constantly explore and innovate in order to achieve the purpose of promotion targets in practice. Recently, we take the call dropping as the topic, and do the optimal work to enhance call dropping indicators. According to actual situation, my work about LFBS15 starts with four aspects： adjustment of categorical attribute parameter, optimization of adjacent dells, BSRXMIN and uplink power control optimization. It is summarized as follows. Of course, optimization of call dropping indicator is a gradual process and requires a selective application from the existing optimization methods in practice. In this way, we can enrich the network optimization experience and enhance the wireless network indicators.
