Optimizating Of China Mobile Yunnan Urban 4G Network And It's Scheme Promotion

As of August 2017,the 4G base station of China Mobile has reached 1.46 million,the users of 4G has reached 6.1 billion.As the same time,the 4G base station of China Mobile Yunnan has reached 80 thousand,the customer of 4G has reached 21.6 million.Especially in the rapid development of urban areas,covers an area of less than 10%,the area less than 10%,but has more than 50% of the base station,more than 50% of the active users of 4G.In the help of China Mobile Yunnan,the thesis has given the way which can meet the network demand for as many people as possible in a limited space,can reduce the percentage of table tennis switching ratio and 4G overlap coverage.This thesis firstly introduce the 4G status of China Mobile Yunnan,then expound the existing problems of the 4G network and put forward the plan.After verificating the scheme,this thesis find out the key factors influencing urban 4G network quality and put forward specific optimization scheme.The next,the optimization scheme have been implemented and the optimization effect have been evaluated.This thesis have found a method to reduce the percentage of table tennis switching ratio and 4G overlap coverage,as well as,improve the average PRB utilization rate of small base stations.Finally,I have modeled the whole optimization process to be a template of urban 4G network optimization for reference to other provinces and cities.
