Common Radio Resource Management strategies are devoted to achieve an efficient usage of the pool of radio resources available in a heterogeneous radio access network context. This paper describes the functionalities associated with the common vision of radio access technologies, the different possibilities in the functional model split and the(More)
Release99 of UMTS (Universal Mobile Telecommunication System) network supports conversational services by means of UTRAN (Universal Terrestrial Radio Access Network) Dedicated transport CHannels (DCH). In this paper we evaluate the impacts of the radio access network on the end-to-end Quality of Service (QoS) of Voice over IP (VoIP) by means of dynamic(More)
The scope of this paper is to provide a detailed description of the selected architecture and the functionalities considered for the AROMA project. This project focuses on a heterogeneous radio access network which includes several Radio Access Technologies (RAT) , namely; UMTS Terrestrial Radio Access Network (UTRAN), GSM/EDGE Radio Access Network (GERAN),(More)
