Technical Solutions And Implementations To Improve The High-speed Mileage Drop Ratio Of 4G Networks

With the rapid development of China's economy,the interpersonal communication is becoming more and more frequent.With the gradual promotion of 4G network,the coverage of the network is gradually expanded.More and more people are using the network,and at the same time,the requirements of social production and other activities on communication services are constantly improving.The competition between the communication operators for users is increasingly fierce.Communication operators attach great importance to the quality of communication network,because it directly affects the users' perception and decides whether has more subscribers.Therefore,how to accurately analyze the performance of the 4G network and intuitively reflect the users' perception become the focus and difficulty of the current network work.In daily work,we find that mobile phone users are prone to 4G interconnection drop during high-speed mobile,which is a very bad experience for users.In view of this phenomenon,this paper will study the factors affecting the 4G network mileage drop ratio from a multidimensional perspective,and effectively improve this phenomenon.We know that there are many factors affecting the 4G network dropping.In this paper,the 4G network dropping situation on the main area of Jiangdu will be classified and counted from a multidimensional perspective.And then the variable analysis method will be used to confirm each factor one by one.On the basis of the current situation investigation,we analyze the reasons influencing the "4G network mileage drop ratio".We have identified eight terminal causes,and made the factor confirmation table from the aspects of confirmation content,confirmation standard and confirmation method,and finally confirmed each factor.Three factors,including the lack of base station points,the failure to implement the management and control responsibility of neighborhood configuration,and the large deviation of base station antenna angle,are the main reasons for the high-speed distance drop ratio of 4G network.For the base station with few points,the implementation plan is to build new base stations,which can improve the signal's weak coverage and improve the communication quality.Neighborhood planning is an important part of wireless network planning,and its quality directly affects the network's performance.Good neighborhood planning is the basic requirement to guarantee LTE network performance.The responsibility of neighborhood allocation control has not been implemented,and the implementation plan is the responsibility of neighborhood allocation control has been implemented to people.For the large Angle deviation of base station antenna,the implementation plan is to accurately adjust the antenna Angle through radio frequency optimization.The concept of "modified range value" is introduced in the radio frequency optimization,and "modified range value" is obtained by reversing the difference between the actual coverage distance of the practical and the theoretical calculation of the coverage distance.The implementation of the three countermeasures has effectively improved the indicators of high-speed distance drop of 4G network in Jiangdu region.The quality of 4G network has been significantly improved and the users' mobile phone surfing has been more smooth.At the same time the users' satisfaction has been significantly enhanced.With the constant popularity of smart mobile terminals and the rapid development of application services,the demand of users for mobile data services is constantly increasing,and the demand for service quality is also constantly improving.The research and analysis of current 4G network technology will promote the development of 5G technique in the future,so that in the future the 5 G network will develop in a diversified,broadband,comprehensive and intelligent direction.
