The radio resource index for real-time service in WCDMA cellular systems

Abstract

In this paper, a radio resource index (RRI) is derived to estimate the radio resource required for a call connection in WCDMA cellular systems. An analytical model is proposed and large deviation techniques are adopted to obtain the RRI. The RRI can transform traffic parameters and quality-of-service (QoS) requirements of the call connection into a measure of resource in a unified metric, while keeping QoS requirements of existing calls guaranteed.
