Design And Implementation Of The Performance Analysis And Forewarning System In LTE Network

With the development of LTE technology and related services,a large number of LTE devices are deployed to the existing mobile networks,and the number them is still growing.LTE community is the most basic unit to provide users with network services,which have been regarded by mobile operators as the core work because the reliable operation of it concerns the quality of the entire network.It is a real concern for mobile operators to monitor the status of LTE network operation in real time,to find potential problems and to analyze and analyze the accurate and timely positioning of the problems.This paper designs a set of LTE network performance analysis and forewarning system for a company in China Mobile.Through this system,it can grasp the running status of the whole LTE network in real time,monitor the status of each LTE cell,and help the mobile network optimization personnel optimize the network resource configuration Network planning and design,improve service quality.LTE network performance analysis and optimization system is based on ZTE,Huawei equipment performance data for network performance analysis.The system consists of performance data calculation module,LTE network load analysis module,key cell performance data analysis module,database module,performance data query module and so on.The data computing module is mainly responsible for the calculation of the original performance data,LTE network load analysis module is responsible for the use of traffic,number of users,wireless utilization and other key performance data and analyze and classify the whole network load by means of partial least squares and BP neural network to provide guidance and digging for network planning.The key cell performance analysis module mainly analyzes the key performance data of the key cell,obtains the warning threshold and obtains the dynamic warning by the clustering algorithm.The database module is responsible for the storage of all the performance data and performance analysis results.The performance query module is responsible for the performance data query and statistical analysis and static warning,and presenting the data and graphics to the user.The system uses the development platform is Visual Studio 2008,the development language is VC ++,the database adopts SQL Server 2008,the algorithm simulation platform adopts Matlab R2014 a.The LTE network performance analysis and forewarning system in this paper has been running for more than 10 months after the adjustment of the company in China Mobile.The results show that the modules are running normally and the system is reliable.The accuracy rate of the whole network is more than 90%,and the accuracy rate of the key district is more than 80%.It can detect the problems in the network operation in a timely and accurate way,which has certain guiding significance to the network planning and satisfies the user’s business needs.
