Study And Application On GSM Mobile Communication Network Optimization

Along with the development of GSM (Global System for Mobile Communications) mobile telecommunication network, more and more users advanced their requirements for network service quality. While the operators also devoted their attentions to improving network performance instead of increasing the network coverage. By means of systematically network optimization, the operators can fully utilize existing network equipment, resource and capacity in order to improve the service quality as well as their Benefits to the maximum extent.Firstly, this study introduce some important ways of GSM wireless optimization techniques such as cellular cell split, spread spectrum, frequency reuse, GSM900/1800 dual band and half rate feature. These methods for the expansion, parameter changes and other network adjustment of traditional base stations have its limitations. In each time segment, different district needs different resources, but the current design of wireless network capacity is based on the peak capacity when busy, which inevitably leads to the wastage of resources. Analyzing the growth trends of telephone calls, this design is difficult to completely adapt all emergency situations of calls uprush, so bring forward the scheme of adjusting and mobilizing carrier frequency resources of mobile cellular network, which has a positive significance for improve network utilization.According to the above content, GSM quality optimization of this region is analyzed and researched, including frequency planning, the quality of the frequency planning rises to the network quantity decision influence, aim at the frequency strain, it can be realized the GSM900/1800 dual-band resources repair with each other and The frequency replies to use by BROADS, it can increase network capacity at the foundation that maintain the good quantity of voice. Loss line, loss line is the hotspot of customer complaints, it is also the Key Performance Indication that measure the network quantity, the interference and the antenna are main causes those result in loss line in BSS, it can be found out problem by the locale test, reason analysis and malfunction orientation, the amount of loss line is reduced and the quantity of voice is improved by closeing interference source, modification of frequency planning, redressal of overlay of cell and redressal of antenna. The problem of handover and equation of trafficload, when the IntercellHandover is normal, the equation of trafficload is poised the equation of trafficload by adjusting parameter, so the problem of handover and equation of trafficload have the close connection, these cells are made of a seamless network by the technology of handover, it can guarantee the continuous to serve to ambulation customer, the descent of network quantity that is led by cell congestion would be avoided by the equation of trafficload, The problem of handover and equation of trafficload will be solved ,through analyze the reason of cell congestion and parameter of the handover optimization.Synthesize to adopt the variety the excellent turning the technique sexually, resolve every kind of problem appeared in the network, excellent turn the network resources install, improving the movement environment of the network, increasing the movement quantity of the network, make network circulated in the best appearance, correspond by letter for the ambulation the emollient technique in offering in fast fierce development support of the business props up with network..
