CDMA 1X Data Service Optimization Technology Case Analysis

With the development of China Unicom CDMA network, CDMA 1X data service along with multitudinous value added services is gradually accepted by people. For example it has the information access, vehicles localization, traffic control, long-distance monitoring and monitor and so on in terms of vertical application. In terms of the horizontal application of the commercial customer, data CDMA 1X services include access to enterprise network, database access, Email etc. Meanwhile, there are some services such as internet access, Web browsing, the email, the e-commerce especially for the public customer. Due to their increasing business volume, enhancing the speed of network accessing is becoming the main focal question that carriers concern most.Data service optimization is quite important as the fact of customer development and data service promotion. This thesis introduced the CDMA network architecture, the wireless features, the difference between data service optimization and voice optimization, the network structure of the data service realization first. Then Based on the wav of CDMA 1X data service access and the use of TCP/IP, the thesis analyzed the main reason of influencing the speed from the wireless network layer, transmission layer and application layer perspective. In order to enable the system to achieve the greatest volume of throughput and the shortest transmission delay, at the same time to provide the best download speed for the "palm broadband" service, the thesis mainly discussed the optimization of TCP/IP parameters and other parameters related to the Radio Link Protocol resending mechanism particularly.CDMA 1X data service is base on the wireless mobile network, and the voice service is the key point of the customer development. But along with the data service development and the popularization, mobile data service is also gradually acknowledged by the customer. Therefore, based on the general analysis of data service, this thesis has provided CDMA 1X wireless service optimization and data service optimization case studies and elaborate the skills and methods of data service optimization according to network maintenance requirements.
