Abstract: Third generation mobile communications networks willsupport audio, video, multimedia data, and speech services. Therefore, it is important that these networks provide quality-of-service (QoS) guarantees. However, provision of QoS in wireless networks becomes complex due to user mobility. The problem becomes even more challenging as recent mobile networks have been implemented based on small size cells (i.e., micro-cell or pico-cell) to allow higher transmission capacity, and thus to achieve better performance. Small size cells increase the handoff rate, and result in rapid changes in the network traffic conditions, making QoS guarantees difficult. In this paper, a novel admissionscheme is proposed that provide high degrees of QoS guarantees for multimedia traffic carried in broadband mobile networks. The proposed scheme combines admission control and bandwidth reservation to guarantee.
