Abstract:

A method based on grid analysis is proposed.The TD-SCDMA coverage areas are divided into 1 km by 1 km grids,whose network quality is evaluated according to the MR data on PS block error rate,PS switch rate and RSCP points,based on which the diagnosis and analysis of network coverage,resident ratio and TD shunting is made combining the grid core network and wireless side of statistical data.Tests are done on the Huangshi TD-SCDMA network by grid analysis method,and the results show that the network metrics are improved significantly.

Key words: MR measurement;TD-SCDMA;network quality analysis;grid analysis
