Development And Application Of Drive Test Software Optimized For Private Network Communication System

As a mature 4G technology,TD-LTE is increasingly used in the construction of wireless private networks.The real environment of building a wireless network is extremely complicated,and it is necessary to use a wireless network planning simulation tool to simulate a realnetwork state.As the basis of the wireless network planning simulation process,coverage analysis can comprehensively display the coverage effect of the entire wireless network and improve the accuracy of the entire network performance evaluation analysis.However,with the continuous evolution of communication technology,the coverage analysis under different communication systems is different,and the requirements of simulation software are constantly changing,which challenges the updating and scalability of coverage analysis systems in simulation tools.The TD-LTE power private network faces common coverage problems such as coverage holes and weak coverage,and needs targeted coverage optimization solutions to solve such problems.In view of the above problems,this paper designs and implements a coverage analysis system based on TD-LTE private network.The system has certain scalability and can cope with the new requirements of the evolving communication system.At the same time,the paper proposes an integrated optimization scheme for TD-LTE power private network coverage performance based on LTErative simulation,which provides a reference for the optimization of private network coverage.The paper mainly includes three parts.(1)Focus on the coverage analysis module in wireless network planning based on TD-LTE.The function of coverage analysis and the coverage calculation method are studied.The important coverage calculations such as signal-to-noise ratio(SNR)and signal-to-interference ratio in coverage analysis are emphasized as well as the calculation process and method of indicators.(2)A wireless network planning coverage analysis system based on TD-LTE is designed and implemented.Based on the functional and non-functional requirements analysis of the coverage analysis system,thesystem is structured and designed according to the sub-module function.The system performance requirements and scalability requirements are correspondingly implemented.The system was designed and implemented,and finally the system was tested.(3)The coverage performance of TD-LTE power private network is analyzed.The coverage problem faced in TD-LTE power private network is expounded.A comprehensive optimization scheme of TD-LTE power private network coverage performance based on LTErative simulation is proposed,which uses simulation tools.The simulation comparison experiment is carried out to verify the feasibility of the coverage optimization scheme and provide reference for the coverage optimization of TD-LTE power private network.
