Abstract

This paper proposes a transient(predictive) connection admission control(CAC) scheme using the transient quality of service(QoS) measure for vertical handover between cdma2000 and WLAN. We derive the transient outage probability as the QoS measure using the fluid flow model. We need an approximate approach using fluid flow model for real-time CAC applications. Based on the outage measure, we compare soft QoS-based transient outage performance against traditional hard QoS-based transient outage performance. Numerical results show that the predictive CAC is a promising approach for vertical handover between cdma2000 and WLAN.
