GSM Radio Network Optimization And Simulation Analysis

In recent years，telecommunications industry of our country has achieved rapiddevelopment, especially the rapid development of the construction and operation ofthe mobile communication network., the new technology of mobile communicationscontinue to be tested and applied, the construction of next generation mobilecommunication networks is also increasing. We should note that the GSM wirelessnetwork is now the most widely used and also the most mature and most stable mobilenetwork, the construction of next-generation networks can not leave the existing GSMnetwork, and it is closely linked to the existing GSM network. The most basic and thelargest volume of business is voice communications business, it is still mainly rely onthe GSM network hosts. At this stage the main content of the GSM wireless networkresearch is planning and optimization.The main purpose of the GSM network planning is to grasp the current networkoperation and various network performance indicators to provide a reference on thenetwork running and maintenance, and provide guidance for the network construction.The role of the GSM network optimization is to solve the practical problems found inthe operation of the existing network, improve network performance, reduce usercomplaints and improve customer satisfaction. Mainly to resolve the poor coveragestrength or no coverage, they lead to the high rate of dropped calls and the low switchrate, switch confusion between the cells, unbalanced traffic and uplink and downlinksignal interference and other issues, so that users can normally use the mobilenetwork.This paper first introduces background and current situation of the research,pointing out the main content of the GSM network planning and optimization at thisstage. And then gives a brief description of the basic principles of the GSM network,introduces the characteristics and structure of the GSM network as well as the type of business, analyzes the characteristics of the dual-band GSM and GSM wirelessnetworks, multiple access techniques, frequency hopping and channel coding, powercontrol and other key technologies, provides a theoretical basis for practical networkplanning and optimization, introduces the content and methods of the GSM networkplanning and optimization. The fourth part of this article gives GSM wireless networkplanning and optimization of Shuangyang region. It collects a large number of actualdata, do a lot of testing, and a number of simulation experiments, do Multi-angleanalysis of Shuangyang existing network. According to the Network practicalproblems of test data and user complaints, it gives a detailed analysis of the detailedanalysis of the causes and optimization steps, uses an advanced simulation softwarefor the simulation compared before and after optimization. It validates theeffectiveness of the optimization method, reflects the simulation method is applied tothe convenience of network planning and optimization. It gives us GSM wirelessnetwork optimization programs that based on the actual and can solve practicalproblems, has a certain practical significance.
