Soft QoS-based CAC Scheme for WCDMA Femtocell Networks

Key features desired from IMT-Advanced network include open architecture for productivity, increased end-user throughput, reduced latency, support for full mobility and end-to-end QoS. A femtocell is a small cellular base station designed for use in residential or small business environments. It connects to the service provider's network via broadband (such as DSL or cable). The IMT-Advanced networks will make extensive use of femtocell, picocell and microcell technologies to deliver very high data rates in high-usage areas along with macro cells. In this paper, we propose a FMC (fixed mobile convergence) network architecture using a femtocell concept. In this case, we propose a new CAC (call admission control) scheme based on Soft QoS for resource allocation. The proposed scheme can effectively satisfy the QoS requirement.
