Data storage 3G and air interface protocol analyzer for next generation mobile communication system

Abstract

The invention provides a data storage 3G and an air interface protocol analyzer for a next generation mobile communication system, wherein, the analyzer is composed of a data collection module, a storage module, a control module, a user interface module and an analysis module. In the invention, when the data collection module performs data acquisition, parameters of base stations or a mobile terminal are not assigned, but the operating frequency thereof is assigned; communication signals of all the base stations which work using the assigned frequency and the mobile terminal in data acquisition location are acquired by a RF module and then stored in a storage unit through I / Q separation and A / D conversion; and when a user carries out data analysis, the assigned parameters of the base stations or a mobile phone are input by a human-computer interface, and then air interface data of corresponding equipment is analyzed according to an air interface protocol, displayed on a screen or stored in a specified data file. Because of large storage content of the storage module and long data acquisition time, the user can easily assign a time point or a time segment to be analyzed and repeatedly test and observe the data in the same time segment using different analytic parameters so as to discover and solve problems. The communication signals of all the base stations and the mobile terminal in a test site are acquired simultaneously, thus easily achieving comparison tests.

Description

technical field [0001] The present invention relates to the test and optimization of the third-generation and next-generation mobile communication system network, the test of the access performance of the base station and mobile terminal of the third-generation and next-generation mobile communication system, and the communication algorithm of the third-generation and next-generation mobile communication system verification, etc. Background technique [0002] The interface between the base station and the mobile terminal of the mobile communication system is an air interface connected by radio waves, and the communication wave signals are transmitted to each other according to the air interface communication protocol. The air interface is the most important and complex interface of the mobile communication system. The communication wave signal of the air interface is analyzed and displayed according to the air interface communication protocol, and the analysis of network ope...

AI Technical Summary

Problems solved by technology

[0004] However, the communication radio signal transmitted in the air is erratic due to the erratic communication environment, so it is not easy to set the optimal analysis parameters

If the parsing based on the preset parameters fails, the test is completely invalid, resulting in a waste of test resources

The test efficiency of the repeated real-time test by adjusting the test parameters is reduced, and the missed test is caused because the past situation cannot be reproduced

In addition, because the parameters are set in advance to test the designated base station and designated mobile terminal, when multiple base station signals and multiple mobile terminal signals can be received at the same place, multiple tests are required to complete the test of all test objects. Repeated testing consumes time, and the information of the terminal under test at the test point is lost due to the existence of time difference, resulting in missed testing, which is not conducive to comparative testing

Using multiple testers can simultaneously test multiple base stations and mobile terminals at the same location, but the cost is too high, and it is difficult to test all mobile terminal signals simultaneously
