Embodiment Construction

[0019] The measurement system used in the present invention is composed of mobile station 220, base station 230 (comprising forward link transmitter 203, reverse link demodulator 206, reverse link performance measurement 204, RTD measurement 205 of mobile station signal etc. Composition), communication network 207, forward link measurement decoder 208, forward reverse link measurement combiner 209, reverse link RTD combiner 210, positioning system 211, network performance analyzer 212 and network assessment server 213, composed of network entities such as measurement command generator 214, such as figure 2 shown.

[0020] The network evaluation system server 213 responds to the user's request, determines the areas that need network evaluation, and then determines which base stations cover these areas according to these areas. At the same time, the network evaluation system server 213 archives the final measurement results, generates reports, and prints them.

Abstract

Quality evaluation system is composed of mobile station, base station, server of network evaluation system, generator of testing command, RTD information combiner of reversal link, positioning server, decoder of test result of forward direction link, combiner of test result of forward link and reversal link, and statistical analyzer of network performance. Server of network evaluation system sends out testing request. Generator of testing command configures base station and mobile station. Mobile station carried out measuring link performance in forward direction link. Base station carried out measuring link performance in reversal link and RTD information for position in reversal link. Combiner of test result of forward link and reversal link combines result measured by mobile station and base station so as to obtain quality parameters in forward link and reversal link. Final result is from statistical analyzer.

Description

technical field [0001] The invention is used for the wireless network quality evaluation of the mobile communication system. Background technique [0002] There are many indicators for evaluating the network quality of the mobile communication system, such as connection rate, call drop rate, voice quality, mobile station transmission power and so on. But in fact, these indicators are determined by the received power of the mobile station and the SIR (Signal Interference Ration) of the signal received by the mobile station. With the development of mobile communication systems, the coverage of base stations is getting better and better, and the signal-to-interference ratio of signals has become the main indicator of network quality. Especially in urban environments with dense traffic, the improvement of signal-to-interference ratio has become a major problem. [0003] Network planning engineers of mobile communication systems generally evaluate the network through drive tests...
