【摘要】：随着城市规模扩大,客户业务需求的持续快速增长,网络结构也在不停的调整过程中,结构问题逐步累积,当业务量上升到一定程度以后,网络质量问题会集中爆发,从而影响用户感知。天水移动公司目前GSM网络存在了较多的上述问题,因此就需要通过分析网络结构,降低网内频率复用度,进而降低网内干扰;进行三高整治,结合话务分析,合理分担话务,通过载波扩减容达到频率复用度优化工作;通过降低天线挂高以及天线下倾角,方位角调整等,优化小区覆盖,使基站小区覆盖更区域合理化,解决天水移动GSM网络重叠覆盖较多的问题,同时大量解决过覆盖造成的干扰,降低网内干扰;天水移动GSM现网大量的无线直放站的使用,在增加覆盖的同时势必会带来质差,干扰等负面效果,采用微蜂窝设备更换现网直放站小区,保障原有覆盖,提升覆盖区域用户使用感知。通过网络优化工作,就能够清楚的掌握天水移动GSM现网干扰指数及具体干扰站点,能够掌握现网“高配置,高站,高直放站”的站点或区域;有了第一手的分析资料,按照本文研究的优化方法,科学实施,合理调整,努力提升整体网络质量,全面改善用户感知。
[Abstract]:With the expansion of the city scale, the continuous and rapid growth of customer business demand, the network structure is also constantly adjusting process, structural problems gradually accumulate, when the volume of business rises to a certain extent, the network quality problems will burst out. Thus affecting the user perception. There are many problems mentioned above in the GSM network of Tianshui Mobile Company at present. Therefore, it is necessary to analyze the network structure, reduce the frequency reuse degree in the network, and then reduce the interferences in the network, carry out three high regulation, combine the traffic analysis, and share the traffic reasonably. The optimization of frequency reuse degree is achieved by carrier expansion and reduction, and the cell coverage is optimized by reducing the antenna hanging height and adjusting the dip angle and azimuth of the antenna, so that the base station cell coverage is more reasonable. To solve the problem of more overlap coverage in Tianshui Mobile GSM network, and to solve the interference caused by overcoverage and reduce the interference in the network, the use of a large number of wireless repeater stations in Tianshui Mobile GSM network will inevitably bring about poor quality while increasing coverage. Interference and other negative effects, the use of microcellular equipment to replace the existing network repeater cell, to protect the original coverage, improve the coverage area users use perception. Through the work of network optimization, we can clearly grasp the interference index and specific jamming stations of Tianshui Mobile GSM network, can master the stations or regions of the current network "high configuration, high stations, high repeater stations", and have firsthand analysis materials. According to the optimization method studied in this paper, scientific implementation, reasonable adjustment, efforts to improve the overall quality of the network, the overall improvement of user perception.
