Key Technologies Of Td-scdma Wireless Network Optimization

TD-SCDMA mobile communication network has already massively deployed in the nation, and how to improve the network-efficiency is the goal of the network operators always. This technology is unique in our country and constructed firstly, so there are more important theory-significance and the use-value in directing of the network construction, the maintenance and the optimization, according to the research and practice in TD-SCDMA wireless network key technologies.This article carried on the thorough analysis in3aspects, Uu interface, core network interface and special optimization. This paper summarized4kind of questions, coverage, drop-call, access, handover, and also discussed the neighbor cell, co-channel interference, proposed the optimization mentality.This paper deeply studied the TD work method and parameter-optimization method in core network aspect. Beside of tracking and counting the dynamic data and the performance indicators, it also innovatively proposed the investigation method about static data and state parameters, which used to assist to position network problems and improving optimization efficiency from another point of view.In addition, accounting to the full process of the jobs, this paper innovatively considered of network influence from core network to wireless network, and changed the traditional thinking about wireless network optimization, which was solved inside of wireless network before. It had significantly improved dropped-call ratio all network, and had improved the service quality all network, through of various measures, such as studying the working process of the core network parameters (T305/T308), such as coordinating adjusting relevant settings in core network.
