Cdma2000 System A1 Interface Protocol Analysis And Implementation

Wth the development of the 3G cdma Digital Cellular Mobile CommunicationTechnologies and quick increase of Chinese Mobile Communication Market 'srequirment to multi-media data service, Mobile Communication Technology isdeveloping from providing simple voice service. low speed data service to providingthe combination of the voice service and the variable band-width multi-media dataservice. Cdma2000 Digital Cellular Mobile Communication Technology has becomethe standard of the 3G Mobile Communication Technology.Wireless access server is a important component of this Cdma2000 DigitalCellulax Mobile Communication system Which is responsed for wireless access and isbased on IP wodriet., it is realized by the WAS software. WAS software is onecomponent of the software of the cdma2000 system and it run on the wireless accessserver. Al interface is a imPortant interface by Which WAS can exchange signal withCS.This text describes and analyse the structure and the characteristic of the newgeneration of the Mobi1e Communication system based on lP worknet and theposition. feature \ the protocal's main content \ main implementation method andprocessing of the Al interface of the WAS.
