| With the gradual release of the domestic commercial LTE network licence of the Ministry,the operators increase to accelerate the pace of LTE network construction and investment,marked by LTE technology 4G network has officially entered the commercial market,accompanied by a simple initial business pilot experience ended,facing the current 2G/3G system and the new LTE network network operations,collaborative development issues in the official business process will follow,this is the problem facing the three major domestic carriers,this issue will include: how to coordinate the development of 2G/3G/4G three network users scale,as in the three network deployment of business,how to ensure that users in the multi network experience.Among them,how to based on the existing network,the rapid and intensive deployment of 4G network,which is a network of user experience,is the priority among priorities of attention of operators,but also related to national information about the future of a series of strategy(such as mobile Internet,such as the implementation of the deployment of smart city).According to the characteristics of three kinds of different technology networks,starting from the differences in coverage and capacity analysis,build three kinds of network sharing strategy and optimal coverage model,and combined with the construction of the scene and performance of existing standard equipment,analysis of 2G/3G/4G network development under the coexistence of optimal construction model,the main contents are as follows:1.multi standard system network base station in the context of the construction of the technical feasibility,this paper analyzes the various modes of the multi carrier system,the different systems of the base station needs to be integrated and analyzed;2.through analysis,covering performance differences,to co site interference factors of switching performance impact,this paper determines the co site construction of various types of tower type selection.3.for the construction of the security service providers of the site,and the total power supply station construction site need room space to do the analysis and research.4.the implementation of the construction process,including the factors associated with the 2G/3G/4G network to consider the situation,combined with the construction of urbanization planning scenarios.The wireless network technology in the future will be towards the wireless access point is more flexible and convenient(base station)construction of the direction of evolution,by using the technique of heterogeneous networks and carrier aggregation,wireless network operators can be flexible according to regional needs to deploy different capacity coverage;through the use of collaborative technology,operators can relax the requirements of wireless network planning and construction the cellular network topology,reduce inter cell interference and enhance the edge throughput;self-organizing network optimization through SON technology,automation operators can realize the process configuration and optimization of network planning,the.Compared to three 2G/3G during the period of network construction in independent execution,restrict each other,through the wireless access system is more advanced in today's 4G network and the evolution of the Internet can support linkage adjustment to three process,reduce the constraints between each other,... |
