Problems solved by technology

[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

Abstract

The invention relates to the communication field, in particular to an integrated comprehensive drive test instrument. It is used to solve the problem of multiple network competition tests at the same time. The method is: the antenna matching circuit module is used to receive the total downlink signal sent by the same radio frequency antenna, and send each downlink signal after frequency band division to the terminal multi-module group The module is a terminal multi-module module, which is connected to the antenna matching circuit module and includes a first-type module set for receiving a downlink signal on a corresponding frequency band and testing and comparing service-related parameters. In this way, it is ensured that the downlink signals come from the same radio frequency antenna, the evaluation error caused by different radio frequency antennas is reduced, the accuracy of the test comparison of related parameters is improved, and the business correlation of different frequency bands belonging to multiple networks can be simultaneously Test and compare parameters, realize test comparison of various networks, reduce test overhead, simplify operation process, and improve the efficiency of test comparison.

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...
