Design And Implementation Of FTP Test Module In TD-SCDMA Network

As a third-generation mobile communication technology mainstream standards,TD-SCDMA in China with independent intellectual property rights, is now officially commercial. With the progress in the commercialization of TD-SCDMA, data services gradually became the mainstream, China Mobile have launched TD data card, TD wireless Internet access to this and other products,major cities have completed the upgrade HSDPA, making data service to download speeds further. In this context, China Mobile for TD test network increasing demand for data services.Via FTP testing, data services can be not only the QoS,find network problems,but also on the network to make an overall assessment of PS-domain performance. Thus, in the wireless assessment test specification,FTP test data service has been tested as an essential test items.In the wireless network testing software to develop FTP test module is particularly important.Through the long investigation and study, this paper test specifications according to China Mobile, combined with network optimization of the actual needs,is designed and implemented a wireless network assessment software in the FTP test module. The test results and practical examples show that the design of test module as reasonably practicable, the test results reached China Mobile's testing requirements.This work completed include: 1.Gaved the demand analysis and design plan of the FTP test module; 2.As the FTP test wireless Internet access, this article enables the successful use of PPP techniques to test the terminal for the modem dial-up connection Internet;3.Study the FTP protocol,analysis of the entire automated test steps required to complete the FTP download test module of the software development work;4.In-depth study of the TD-SCDMA air interface RRC layer protocol, GSM/GPRS core network layer 3 protocol of the PS domain signaling the completion of decoding,event analysis capabilities of software development work;5.Application of our development module, the network of TD practical test, the test results consistent with the actual situation of the network, focusing on the FTP problem of dropped calls test analysis and the results show that we developed the test module as reasonably practicable;6.For FTP test module was predicted.
