ARROWS UMTS Test-bed Description

چکیده
The analysis of radio resource management (RRM) strategies in a UMTS network and the impact that these strategies have on the end-to-end behaviour of multimedia applications with Quality of Service (QoS) requirements is one of the topical communication fields. Within the IST ARROWS (Advanced Radio Resource Management On Wireless Services) project a real-time UMTS demonstrator is being developed to perform this analysis. The demonstrator platform is built over a network of personal computers and copes with the real-time restrictions imposed by the emulation of UMTS transport capabilities. This paper describes the global architecture of the ARROWS test-bed and provides some implementation-specific issues like real-time operation handling.

متن کاملIP-based transport of voice traffic in the UMTS radio access network: analytical study and empirical validation Transport basé sur IP du trafic voix dans le réseau d’accès radio UMTS: étude analytique et validation empirique
In this paper, we investigate the IP protocol as a transport option for the user traffic in the UMTS Terrestrial Radio Access Network (UTRAN), where stringent delay bounds are to be met for both real-time and non real-time traffic. We focus on real-time voice traffic and present an analytical model for the multiplexing and transport of voice channels in the UTRAN using IP. The novelty of our mo...
متن کاملA Simulation Tool for Dimensioning and Performance Evaluation of the UMTS Terrestrial Radio Access Network
The efficient support of multiple traffic classes with different quality of service requirements (end-to-end delay, jitter, loss) poses an extraordinary complexity in the design of third-generation mobile networks. This task becomes especially critical for the access network, where radio and transmission resources are usually scarce. In this paper we present a simulation model of the ATM-based ...
