Design And Implementation Of Radio Environment Evaluate Module Of TD-SCDMA

By the support of the China government and China Mobile, the network construction is in full swing. With the progress of the development of network construction, the testing of network quality has become the focus of work.After the completion of large-scale construction of the wireless network, It is need to test and evaluation the whole wireless network to get the ststus of the network.It is necessary not only just maintaining the network quality, but also to optimizate the perfomace of network.Radio Environmental assessment as a very important aspect of network evaluation, It is use to evaluate the radio network's coverage and service quality in the current region. Radio Environmental assessment can help the engineer to get the current situation of the network and optimize it better.wireless mobile network testing software help people learn and master the operational status of the wireless network through collecting and analyzing massive test data. The testing software must pay attention to the assessment function in this field, while environmental quality evaluation module, the important function module, is responsible for the assignment of analyzing and assessing the wireless environment. Thus, the design and development of wireless mobile network testing software with wireless environment quality assessment function has a very important value.With the "Design and Implementation of the Radio Environment Evaluate Module of TD-SCDMA" as research focus, this paper mainly complete the following work: 1) Deeply study of TD-SCDMA network structure and network optimization. Based on those knowledge, design the radio environmental assessment model, identify the three elements of the assessment model: Coverage, Interference, and Pilot Pollution.2) Analysis the function requirement of wireless environment evaluate module, especially the evaluation algorithm, contains the coverage, interference and pilot pollution.3) Design and implement the basic function of wirless environmental assessments, including access to data from the database, analyze data, display results and save the reports.4) Design and implement the threshold manually set function, that the parameters of the threshold can be adjusted according to actual situation at anytime.5) Doing a large number testing of the module, modified assessment algorithm development and doing the future prospect.
