The number of users employing multimedia services in cellular networks has been increased dramatically in the last decade. Multimedia services are more demanding compared to traditional voice services in terms of bandwidth availability and integrity. The capacity and the bandwidth reservation on demand according to QoS requirements are key concepts in mobile cellular communications. The available frequency spectrum is limited and the demand for enhanced mobile user facilities is increasing day by day, hence the channels must be reused as much as possible to increase the system capacity. Existing
and proposed channel assignment strategies have to be transformed to support efficiently the new demanding multimedia services. Through this paper we present a review of the most known channel assignment strategies, as well as their QoS aspects and we propose new DCA variations and a channel architecture adapted to QoS requirements for supporting multimedia services. We also present some strategies, models and conclusions for algorithm evaluation based on experimental results.
