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 automatic identification of TD-SCDMA network cell scenes and optimization of TD-SCDMA system parameters according to cell scenes, specifically a method of TD-SCDMA system parameters based on automatic scene analysis . [Background technique] [0002] TD-SCDMA, as an independent and innovative 3G standard in China, adopts time division duplexing. The uplink and downlink channel characteristics are basically the same. Therefore, it is easier for the base station to estimate the uplink and downlink channel characteristics based on the received signal. In addition, it also has the inherent advantages of smart antenna technology, reducing the number of users. Interference, local frequency utilization. Due to the lack of the time division duplex system itself, there are inevitably many problems in the network, such as the relay handover problem caused by coverage. Th...
