【摘要】:隨著城市規(guī)模擴(kuò)大,客戶業(yè)務(wù)需求的持續(xù)快速增長,網(wǎng)絡(luò)結(jié)構(gòu)也在不停的調(diào)整過程中,結(jié)構(gòu)問題逐步累積,當(dāng)業(yè)務(wù)量上升到一定程度以后,網(wǎng)絡(luò)質(zhì)量問題會(huì)集中爆發(fā),從而影響用戶感知。天水移動(dòng)公司目前GSM網(wǎng)絡(luò)存在了較多的上述問題,因此就需要通過分析網(wǎng)絡(luò)結(jié)構(gòu),降低網(wǎng)內(nèi)頻率復(fù)用度,進(jìn)而降低網(wǎng)內(nèi)干擾;進(jìn)行三高整治,結(jié)合話務(wù)分析,合理分擔(dān)話務(wù),通過載波擴(kuò)減容達(dá)到頻率復(fù)用度優(yōu)化工作;通過降低天線掛高以及天線下傾角,方位角調(diào)整等,優(yōu)化小區(qū)覆蓋,使基站小區(qū)覆蓋更區(qū)域合理化,解決天水移動(dòng)GSM網(wǎng)絡(luò)重疊覆蓋較多的問題,同時(shí)大量解決過覆蓋造成的干擾,降低網(wǎng)內(nèi)干擾;天水移動(dòng)GSM現(xiàn)網(wǎng)大量的無線直放站的使用,在增加覆蓋的同時(shí)勢必會(huì)帶來質(zhì)差,干擾等負(fù)面效果,采用微蜂窩設(shè)備更換現(xiàn)網(wǎng)直放站小區(qū),保障原有覆蓋,提升覆蓋區(qū)域用戶使用感知。通過網(wǎng)絡(luò)優(yōu)化工作,就能夠清楚的掌握天水移動(dòng)GSM現(xiàn)網(wǎng)干擾指數(shù)及具體干擾站點(diǎn),能夠掌握現(xiàn)網(wǎng)“高配置,高站,高直放站”的站點(diǎn)或區(qū)域;有了第一手的分析資料,按照本文研究的優(yōu)化方法,科學(xué)實(shí)施,合理調(diào)整,努力提升整體網(wǎng)絡(luò)質(zhì)量,全面改善用戶感知。
[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.
