Study And Practice Of CDMA 3G-1X Data Network Optimization Project

The third generation mobile communication is coming.CDMA 3G-1X is thepreparative third generation mobile communication network, which is the CDMA2000first stage, we also call it the 2.75th generation of mobile communication. The designplan for China Unicom 3G-1X network takes the voice model for reference.Thenetwork construction and the network cover also defers to the voice demandimplementation. With data user quantity increase, the current operating CDMA 3G-1Xnetwork can't adapt to the data service, because of the difference technologycharacteristic between data service and voice service. Synthetically using the chart, thetable, the formula, the script, testing tools and Multi-branch discipline knowledgeincluding wireless communication, Exchange core network, TCP/IP.This subject studiesCDMA 3G-1X data network optimization technology, implements the ShenyangUNICOM optimization project. The project solves problems which exist in the currentnetwork and enhances the network performance and efficiency. The subject elaboratedthat CDMA 3G-1X data network is the advanced and complicated technology. Thesubject design CDMA 3G-1X data network test plan. With voice test software andhardware, this subject research data network CQT and DT method. The data test plan isdesigned with computer, GPS, CDMA 3G-1X terminal, FTP server and the voice testsoftware. The subject studies CDMA 3G-1X data network KPI gathering method, takesfull advantage of the existing network statistics function.The project use measuringinstrument gathering network signaling. The script is designed to gather KPI. Thesubject improves the network quality through changing parameter. New operationmechanism and characteristic about TCP in CDMA 3G-1X network is discovered.Highly effective TCP network based on CDMA 3G-1X network is constructed. ThePPP success ratio based on CDMA 3G-1X data network is enhenced. The ShenyangUNICOM CDMA 3G-1X data network optimization project is designed andimplemented. The data network optimization methods and benefits for CDMA 3G-1Xare summarized.
