A testing device and method for base station voice communication

Abstract

The invention discloses a test device of base station voice communication and a method thereof. The method comprises the steps that a value of a frequency point, a calling path, a called path and a corresponding relationship of the calling path and the called path are configured by a master control center module in advance; during testing, the master control center module sends a call command to the calling path of a baseband processing module and the calling path initiates a call, and then a base station system establishes the connection between the calling path and the called path; after the connection is established, the master control center module sends standard voice signals to the baseband processing module and a tone judgment module respectively. The baseband processing module sends the standard voice signals to the corresponding called and / or calling paths in the calling and / or called paths. The standard voice signals returns after passing through a router of the base stationsystem and voice signals received by the called and / or calling paths are sent to the voice judgment module. The received voice signals and the standard voice signals received from the master control center module are compared by the voice judgment module and then calculated to obtain voice test results.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a base station voice communication test device and method, which can be widely applied to the deployment verification test, research and development test and production test of the base station. Background technique [0002] In the base station deployment verification test, R&D test and production test in the communication field, it is often necessary to conduct a voice communication test on the base station system to verify whether the base station system can work normally. Usually, it is all manual dialing, first make a voice call, and then conduct a voice call test. This type of testing is inefficient and the test volume is too small to accurately measure voice communication performance. If the voice communication performance of each carrier of the multi-carrier base station system is tested, each carrier needs to be tested manually, which greatly reduces the efficiency ...

AI Technical Summary

Problems solved by technology

This test is inefficient and the test volume is too small to accurately measure voice communication performance

If the voice communication performance of each carrier of the multi-carrier base station system is tested, each carrier needs to be tested manually, which greatly reduces the efficiency and limits the convenience of the test

At the same time, it is too subjective for the operator to judge the voice quality by himself, and different operators have inconsistent voice quality judgment standards, which leads to the uncertainty of the test results

[0003] In the prior art, there are systems and methods that use computer sound cards to sample voices for simple identification to achieve large-capacity voice testing. However, since this design uses PC sound cards to sample and send voices, each terminal needs to be connected to a microphone channel separately. And one channel of the handset, and each terminal needs to be connected to the serial port for communication conversion, the test connection is complicated, and it is not convenient for efficient automated testing

Among them, the voice signal of the test terminal needs to be sampled by the sound card and converted by the microphone, which increases the design cost and reduces the test accuracy.

At the same time, each wireless test terminal is independent and can be tested directly in the air wireless interface. When multiple base stations are tested at the same time, when the same carrier frequency appears in the base station configuration, it will cause carrier frequency interference, resulting in test failure.
