The Design And Realization Of SMS Module In TD-SCDMA Drive Test Platform

Up to now, the third phase of China's TD-SCDMA network construction has been completed, covering over 70% of the cities of china and the customer had already exceeded up to five million. TD-SCDMA which is a new kind of wireless telecommunication system, and its rapidly development brings a huge workload for the network optimization. Using Drive-Test software to do Drive-Test is one of the most important means to find out network problems at this stage.This paper focuses on the research and design of the SMS test module in TD-SCDMA Drive-Test system. We give the needs and the design of the SMS module by studying the whole structure of the system and China mobile's standards for Drive-Test software. Three are three sub-modules totally in the SMS test module, they are serial communication sub-module, signaling message parsing sub-module and SMS Test thread sub-module. According to the needs and the design given, we realized all the features of the three sub-modules by coding using VC on Windows Operating System. For the point-to-point SMS delay error is so large, and it can not reflect the real conditions of TD-SCDMA system, we propose a new calculation method. Realization by coding and Comparison are done to show that the delay according to our method is more reasonable.Practical results show that our proposal is reasonable and effective, our module is stable and reliable, and can give a better reflection on network conditions and meet the requirements of wireless network test. And also hope that our method of calculation method can be helpful to improve the wireless network test.
