Abstract

The invention relates to the technical field of wireless communication, in particular to a TD-SCDMA (time division-synchronization code division multiple access) system parameter method based on automatic scene analysis, comprising: a base station tracks movement of a terminal in the whole cell through an intelligent antenna. The method is characterized by comprising the following steps: acquiring cell working parameters, a three-dimensional electronic map, a calibrated propagation model, DT (delay time) data and OMC (operation maintenance center) COUNTER data; carrying out automatic scene cluster analysis on a geographical scene and a wireless scene; optimizing network system parameters; carrying out simulation evaluation on optimized parameters; if the parameters reach the optimization object, finishing optimization; and if the parameters do not reach the optimization object, optimizing the network system parameters again. Compared with the prior art, the invention has the advantages that data sources adopted for optimization are abundant; the optimization method is simple and convenient; cell scene cluster analysis is adopted, thus cell problems can be accurately positioned; and an expertise library module is adopted, thus network problems can be solved appropriately.

Description

[technical field] [0001] The present invention relates to the field of wireless communication technology, and relates to the automatic identification of TD-SCDMA network cell scene and the optimization of TD-SCDMA system parameters according to the cell scene, specifically a TD-SCDMA system parameter method based on automatic scene analysis . [Background technique] [0002] TD-SCDMA, as China's self-innovated 3G standard, adopts time-division duplexing, and the characteristics of the uplink and downlink channels are basically the same. Therefore, it is relatively easy for the base station to estimate the characteristics of the uplink and downlink channels according to the received signal. In addition, it also has the inherent advantages of smart antenna technology, which reduces the time between users. Interference, local frequency utilization. Due to the absence of the time division duplex system itself, there are many problems in the network, such as the relay handover pr...
