Abstract

Beyond 3G mobile communication systems are being defined as the integration of diverse Radio Access Technologies (RATs) into what is generally known as heterogeneous wireless systems. One of the main challenges that such systems must overcome is the ability to guarantee the interoperability and efficient management of the different RATs in order to provide the user with a suitable and consistent Quality of Service (QoS) level. To this end, one of the key elements that must be considered by the network provider is the Common Radio Resource Management (CRRM) of the different RATs. The work reported in this paper is focused on the development of new CRRM techniques designed to efficiently distribute traffic across the diverse RATs of a heterogeneous wireless network. The main objective of this work is to provide solutions that are able to fulfil user QoS requirements and to optimally exploit overall system resources
