This manuscript introduces a novel design concept for advanced mobile terminals with radio network aggregation capability and enhanced Quality of Service (QoS) provisioning for various multimedia services in heterogeneous wireless and mobile networks. We establish a new module that provides the best QoS and lowest cost for any given multimedia service (voice, video and audio) by using simultaneously all available wireless and mobile networks for a given traffic flow. The performance of our proposal is evaluated using simulations with multimode mobile stations carrying multimedia traffic in heterogeneous environment with coexistence of multiple Radio Access Technologies, such as 3G, 4G as well as future 5G radio access networks. The analysis of the proposed framework for radio networks aggregation in advanced mobile terminals has shown overall better performances regarding the achievable throughput and multimedia access probability in heterogeneous wireless and mobile environment.
