The International Telecommunication Union devotes continuously to the third generation mobile communication system standardized work, and from submission ten kind of wireless transmission technology (RTT), designated Europe proposed WCDMA, North America proposed CDMA2000 and UWC-136 take 3G the main technology, but the WCDMA technology will be a mainstream.This article first introduced the WCDMA background and the present situation, have carried on the earnest analysis to the WCDMA system wireless interface structure, has studied the WCDMA network space connector to high speed grouping service processing, finally will study the result union link company WCDMA network concrete application which obtained to obtain a set in view of the wireless grouping service optimization processing flow, and aimed at the space connector each and each kind of parameter has obtained a set of foundation data. Has confirmed the practical work through the experiment to the space connector and the high speed grouping service optimization and the application.
