GSM base station voice service automatic testing equipment and method

Abstract

The invention relates to an automatic test device (100) of GSM base station voice service and method therefor, wherein, the device comprises a console (110), a voice evaluation module (120), a voice service receiving transmitting module (130) and an interface matching module (140); the method includes: a test base station is gated by the console (110) through software controlling a multi-channel radio frequency switch (143); a voice path connection is established by a script code which controls a voice sender (131) and a voice receiver (132); the voice evaluation module (120) sends voice test signals with specified sequence and contrast analyzes difference of sent voice and received voice, then sends analysis result to the console (110) for data processing and outputing test result. The device and method the disturbance of production test site environment to base station test is shielded by the device and method, an automatic operation for parallel test of a plurality of base stations is realized, the production test efficiency is improved.

Description

technical field [0001] The invention relates to voice service testing, in particular to a GSM base station voice service automatic testing device and method thereof. Background technique [0002] Global System of Mobile communication, referred to as GSM, is currently the largest digital cellular mobile communication system and belongs to the second-generation mobile communication system. In the GSM-based mobile communication system, the realization of high-quality voice calls is the basis of GSM base stations Function, the base station needs to realize the conversion of wireless signals, complete the transmission and reception of wireless signals, the modulation and demodulation of baseband signals, and the transmission of service signals, and also receive signaling from the switching network to complete the control of the base station system. In the entire GSM mobile communication system, the base station is at the terminal of the system, and its output is much larger than ...

AI Technical Summary

Problems solved by technology

[0003] The traditional test method is to use the mobile phone to dial the mobile phone to test the voice service of the GSM base station. This test method has the following disadvantages: ① Since the production site needs to test many base stations, and the mobile phone is connected to the base station through the air interface, multiple The electromagnetic pollution of the base station will cause the distortion of the test results, and the wireless pollution will affect the test results of the voice service; ②The way of mobile phone access requires manual operation, and the operation of the test process is very complicated. Since the test of the voice service requires a long test time, the base station The attachment function, the continuous connection and transmission function test of the base station are very time-consuming, and the manual test efficiency is very low; ③ During the aging process of the base station, it is necessary to regularly test the voice service, which cannot be realized by using the existing test method; ④ Cannot Realize the parallel test of multiple base stations; ⑤ unable to record the real-time transmission rate of the voice service test
