In this paper, we propose and evaluate an adaptive resource allocation scheme for 3G multimedia systems. We give a discussion on the inherently multi-component nature of multimedia applications for wireless communication systems, and describe our multi component teleservice model. Subsequently, we introduce our adaptive resource allocation scheme based on the described teleservice model. The multimedia traffic and the adaptive scheme is modelled and analysed next using queuing theory. The scheme is evaluated and compared against the conventional schemes, namely the non-priority scheme and the guard channel scheme, using performance results for blocking probability and dropping probability. We demonstrate that the proposed scheme is more flexible and efficient in guaranteeing QoS than the conventional schemes.
