Technology Of PHS Network Optimization

Along with the PHS customers increasing of quantity, the company operators need to enlarge the equipment continuously in order to adapt to the development's need. At earlier period construction and development, it would inevitably exit circumstance of not reasonable allotment of some resources; At the same time, because of the development of social economy , city developments and city planning result in the environment variety, and influence the originally possessed network cover. All of these require replaning part of the network and optimizing it. Customers can get the service of better superior quality, on the other hand the business enterprise can increase reputation, guarantee market share, and get the steady development.During the network optimization, the main problem that we faced is about cover problem, synchronous problem, cut-over problem, drop-call problem and so on. While we provide the optimization project, aim at these problems ,we should consider all kinds of factors, and can't solve problem from an aspect. For example, for the sake of improving cover the scope, we can increase the antenna high degree. But at the same time that would lead to the interferences among the cell stations. For some places not far away from the standing cell station, the result of cover would on the contrary become worse. Therefore, during every time of optimization, we should completely analyze the network's various functions. After we improve the network function by the technical method, we made the analysis again to make sure whether the network functions get completely improvement.In the network optimization process, PHS optimization persons work with the various maintenance and optimization tools. For example, they made statistics and seach by network management system and cell station management system. They obtain analysis dataes by obvious map tools, test tools, imitate tool and...
