| In recent years, our country's mobile communication enterprise developed swiftly and violently, the GSM numeral mobile communication enterprises are developing vigorously. Along with mobile subscriber's increasing, the network scale expanding, the network capacity fast increasing, the mobile subscriber distribution unceasing change and was more and more highly request on the network quality. Along with mobile gradually reforming, the mobile communication market unexpectedly struggle intensifies, the compete between various telecommunication operation business become more and more intensive. Network quality has become the assurance success or failure key of the network operation business. The network optimization is improves the motion network quality the most direct effective method. "Continuous optimization to the network, can guarantee the network the usability, improves the correspondence quality unceasingly" .In recent years, Harbin mobile GSM network developed at an astonishing speed, the mobile network was at the large-scale construction condition throughout, and the user quantity increase has often surpassed expert' s estimate. Under the market competition actuation, the mobile network unceasing militancy, the network planning continual readjustment, and an issue of project has not completed, meanwhile new issue of construction oneself starts, causing the project existence overlap phenomenon. The pried between constructions and becoming into service is very short, while the cycle is very short as well as user quantity grows the very quick. Because the network is at the construction stage throughout, but does not have relatively stable time to carry on the optimization, the improvement network plan and the supervisory work, thus affects the network operation quality, the working efficiency and the service level. The existing network architecture urgent needs to optimize and adjust. Therefore, the improvement network correspondence quality, guaranteed the network the normal operation and the security, become an important topic. This project is precisely under this background proposed and implements. Through moves the GSM wireless optimization case and the statistical information analysis to Harbin, locates Harbin to move the present net network breakdown prominent aspect accurately, formulates the realistic present net optimization plan and implements, improves the present net network quality effectively, achieves the network truly the plan, the construction, the optimized closed loop management. Through applies the wireless network optimization system in Harbin's concrete network environment, has carried on the network optimized analysis and the design. Through the proven graph and the data this article obtains theoretical analysis, network architecture adjustment and GSM wireless parameter extraction accuracy, the network quality had the remarkable enhancement, and it has obtained the good optimized effect. |
