System for data traffic delay time test and error cancelling method

Abstract

The invention discloses a data service time delay testing system, which includes a network interface module, a terminal, a data acquisition module, a data reduction module and an error elimination module. The invention also discloses a method for eliminating the error during the data service time delay test, the method records the data traffic of the PS service and measures the actual time delay; a test data package simulating the data traffic of the PS service is transmitted by the terminal according to the data traffic of the actual PS service to test the time delay of the simulation test; the systematic error can be obtained by subtracting the one-way absolute time delay when the time delay testing system transmits the test data package from the time delay of the simulation test; then the actual time delay of the PS service can be obtained by subtracting the systematic error from the time delay of the actual test. The invention enables the customer to accurately measure the data time delay of the PS service in the TD-SCDMA system, which can provide precise analysis and positioning basis for the QOS problem during the application of the PS service.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a system for testing data service time delay and an error eliminating method. Background technique [0002] With the continuous maturity and improvement of the TD-SCDMA system, the traffic of service plane data and the end-to-end delay test have become important network indicators that the industry pays attention to. At present, the commonly used test method is to obtain the log information (log) of the service plane data at the upper layer of the user equipment (UE, User Equipment) and the Gi interface respectively, and compare the difference in time points in the log information to perform delay calculation or directly use The delay test tool realizes the delay test of the network by simulating the data traffic of the service plane. [0003] However, for the radio access network (RAN, Radio Access Network) system in the TD-SCDMA system, which is a key part of the time delay...

Problems solved by technology

In addition, even with the same delay test tool, due to the different data collection capabilities of the network interfaces between different devices, there will be certain measurement errors

Therefore, the existing delay test tools cannot eliminate the time error generated in the actual delay test process, but its existence has seriously affected the accuracy of the delay test results, so that the delay test results cannot be Provide accurate analysis and positioning basis for quality of service (QOS, Quality of Service) problems in actual business applications
