Integrated comprehensive road test instrument

Abstract

The invention relates to the field of communication, in particular to an integrated comprehensive drive test instrument. The instrument is used for solving the problem of simultaneous competing test of multiple networks. A method comprises the following steps that an antenna matching circuit module, and the receiving module is used for receiving a total downlink signal sent by the same radio frequency antenna; the antenna matching circuit module is used for distinguishing frequency bands of downlink signals, sending the downlink signals subjected to frequency band distinguishing to the terminal multi-module module, and the terminal multi-module module is connected with the antenna matching circuit module, comprises a first type module set, and is used for receiving one path of downlink signals on the corresponding frequency band and testing and comparing service related parameters. Thus, downlink signals are ensured to come from the same radio frequency antenna; the evaluation error caused by different radio frequency antennas is reduced; compared with the prior art, the accuracy of testing and comparing the related parameters is improved, the service related parameters of different frequency bands belonging to various networks can be tested and compared at the same time, the test comparison of various networks is realized, the test overhead is reduced, the operation process issimplified, and the high efficiency of the test comparison is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an integrated comprehensive drive test instrument. Background technique [0002] With the rapid development of mobile networks and the continuous growth of the number of users, in order to improve the quality of network services in a short period of time, testers need to test the radio frequency parameters, signaling, service quality and other performance parameters of mobile networks of various operators through test instruments. Evaluation mainly collects and analyzes various test data through comprehensive drive test instruments. [0003] The existing comprehensive drive test instrument only includes the frequency scanner module and one module, and it is not possible to test multiple operators at the same time. In addition, if multiple modules are used to test multiple operators, multiple modules are shared In the case of multiple antennas, it is impossible to accurately evaluate th...

[0003] The existing comprehensive drive test instrument only includes the frequency scanner module and one module, and it is not possible to test multiple operators at the same time. In addition, if multiple modules are used to test multiple operators, multiple modules are shared In the case of multiple antennas, the evaluation deviation of test results caused by antenna errors cannot be accurately evaluated, which reduces the accuracy of test results, increases test overhead, and wastes network resources
