Abstract
Current and next generation wireless networks including 3rd generation (3G) and beyond are expected to provide a wide range of multimedia services with different QoS constraints. Call admission control (CAC) and resource reservation (RR) for mobile

communication are of the most important issues that guarantee system efficiency and

QoS required for different services in a very scarce resource as the radio spectrum. As forced call termination due to the handoff call dropping are generally less desirable than blocking a new one, handoff calls should have a higher priority than new calls. This paper investigates the concepts of sharing resources and reservation for WCDMA systems with the unique feature of soft capacity. Voice... (More)

As forced call termination due to the handoff call dropping are generally less desirable than blocking a new one, handoff calls should have a higher priority than new calls. This paper investigates the concepts of sharing resources and reservation for WCDMA systems with the unique feature of soft capacity. Voice and data traffic are considered, and further classified into handoff and new requests. The reservation thresholds are dynamically adjusted according to the traffic pattern and mobility prediction in order to achieve maximum channel utilization while guaranteeing different QoS constraints. Blocking probability, dropping probability, and channel utilization are used as benchmarks for the proposed scheme. (Less)
