Phone standby time in cdma2000: the quick paging channel in soft handoff

Abstract

cdma2000 is one of the proposals currently being reviewed for the 3G systems. This paper addresses one of the areas of improvement of cdma2000 over the IS-95based systems-the standby time of the phone. This paper proposes a novel scheme for the paging channel by splitting it into three parts. It analyzes the design of the quick paging channel (QPCH) and characterizes its performance for various conditions. This paper also looks at a way to put this common channel in soft handoff, thereby improving the reliability and leading to a better standby time for the cdma2000 phones. Both the physical layer and network implications are analyzed in detail.
