Abstract :
A radio resource index (RRI) is derived to estimate the radio resource required for 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 resource measure in a unified metric, while keeping: QoS requirements of existing calls guaranteed.
