Road measuring and recording device and system

Abstract

The recording device includes following modules: being in use for receiving info of road measure from exterior by using three working frequency ranges of CDMA, the communication module (CM) locates position of the recording device of road measure as well as carry out communicate with network or other devices based on received signal; process module is in use for carrying out processing and analyzing on the signal received by CM based on the located info provided by the locating module as well as for storing the processed data and analyzed result to the memory module; the memory module in use for storing diversified info; the control module is in use for controlling each module in the recording device based on user's operations and / or controlling each module through the received remote control signals; power-supply distribution module is in use for supplying power for each module, and stops supplying power when one or more modules do not work.

Description

technical field [0001] The invention relates to the testing field of mobile communication, in particular to a drive test recording device and system. Background technique [0002] As 3G large-scale commercialization is approaching day by day, TD-SCDMA, as China's own 3G standard, will become the first standard with a 3G license in China, so the commercialization process of TD-SCDMA system is more urgent. At the same time, the commercial prospect of TD-SCDMA is becoming increasingly clear. The operating efficiency and operating income of mobile communication networks are ultimately attributed to the problems of network quality and network capacity, which are directly reflected in the interface between users and operators. Network optimization has become one of the daily core tasks of great concern to operators. Therefore, while improving the performance of system equipment, how to improve the level of TD-SCDMA network planning has become a top priority. "If you want to do a...

Most of the current data acquisition front-ends are test mobile phones with special software inside, which has great limitations in the application environment

Moreover, the function is limited. After the mobile phone enters the cell, it can only record and test the data of the serving cell and its adjacent cells. If there is no relationship between adjacent cells, even nearby cells cannot obtain relevant information; and it cannot provide a wider frequency band. It only supports a single frequency band at the same time, which cannot meet the needs of network planning and optimization, and is not suitable for large-scale wireless network drive testing
