　　The core network KPI data、system parameter is one of the GSM network optimization analysis key domain of network optimization. Optimization engineers will deal with core network database,system parameter performance data to analysis fistly. In order to improve network performance synthetically they analyse the performance and modify parameters in core network database by modify system parameter,handover, balance the traffic.The purpose of this master’s thesis was to investigate the coverage plan...
