In third generation (3G) wireless systems we have a number of resources being used exclusively and simultaneously to satisfy the requirements of an arriving Multimedia call. This would require the occupation and release of these resources to be in a manageable fashion. In this paper, we discuss a multi-component teleservice model for multimedia applications. Subsequently, based on this teleservice model, we introduce and analyse a multi-component based resource allocation scheme (MC-RAS) for call and traffic management that exploits the multi-component nature of multimedia traffic. Practical network parameters were used to evaluate the performance of the scheme as compared with the standard approach based on the single multimedia stream flow. The proposed scheme shows better performance in terms of reducing blocking probabilities.
