Upper layer enhancements for fast call setup in cdma2000 revision D

Fast call setup (FCS) technology, a recent enhancement in revision D of cdma2000^® in 3rd generation partnership project 2 (3GPP2), is a set of mechanisms for reducing call setup latency. FCS technology comprises MS tracking mechanisms, channel assignment procedures, paging mechanisms, and traffic channel initialization procedures. The combination of these techniques contributes to the improvement of the overall call setup delay. This article discusses the functional aspects of these enhancements, and their quantitative and qualitative performance.
