“…The presence of two or more radio network systems in the same area is becoming more and more frequent as fourth generation systems will be composed of heterogeneous networks [1]. Various interworking and handover strategies have been presented in the literature for the interworking between 3G and WLAN [2] [3].…”

In this work we develop Markovian models to study the dynamics of elastic calls in a cell served by HSDPA and WiMAX systems. We first present analytical models for interference and throughputs in WiMAX and HSDPA. We then consider two different strategies of Joint Radio Resource Management (JRRM) with or without inter-system vertical handovers and show how to calculate the steady-state probabilities and the performance measures (blocking probabilities, mean sojourn times, loads). Our numerical results compare the different JRRM strategies and point out the advantages and drawbacks of each of them. We find out that, although JRRM with vertical handover achieves the best performance, the throughput maximising strategy without inter-system handovers has an acceptable performance and may be adopted in the first cooperative networks until constructors' handover solutions become more mature.

“…There is an age-old concern of the usefulness of academic research in shaping ripe technological paradigms. Just as the current suspicion of 5G and 6G, researchers in the 3G era have already questioned 4G for whether it has suffered a lot of trendy buzzwords [20]. Meanwhile, it is noticed that the evolution of wireless communications does not fully obey Moore's Law, even though the performance of wireless communication systems is highly related to the processing capability of electronics installed [20].…”

“…Although technological breakthroughs are of great importance, it is conjectured that the dominant factors for improving practical cellular systems in recent years refer to a higher number of base stations (BSs) and a wider radio spectrum in use [2,5,7,8]. The former is a capital-intensive growth pattern, and the latter is more related to electronics and manufacturing industry [20], which might not be directly associated with the PHY research. In this paper, we follow the broad definition of PHY research within the wireless community.…”

The controversy and argument on the usefulness of the physical layer (PHY) academic research for wireless communications are long-standing since the cellular communication paradigm gets to its maturity. In particular, researchers suspect that the performance improvement in cellular communications is primarily attributable to the increases in telecommunication infrastructure and radio spectrum instead of the PHY academic research, whereas concrete evidence is lacking. To respond to this controversy from an objective perspective, we employ econometric approaches to quantify the contributions of the PHY academic research and other performance determinants. Through empirical analysis and the quantitative evidence obtained, albeit preliminary, we shed light on the following issues: 1) what determines the cross-national differences in cellular network performance; 2) to what extent the PHY academic research and other factors affect cellular network performance; 3) what suggestions we can obtain from the data analysis for the stakeholders of the PHY research.

A New Access Control Solution for a Multi-Provider Wireless Environment

et al. 2005

The fundamental goal in future 4G mobile multi-service networks is to provide an efficient mobile computing environment. We presume that future terminals will be equipped with multiple heterogeneous wireless interfaces. We want to enable each user to seamlessly move between different providers' networks. Besides seamless roaming, a key consideration is also devoted to quality-of-service provision. In this article, we propose a model and an architectural framework for supporting quality of service in the context of interconnected multi-provider wireless systems. The proposed integrated COPS-based management and RADIUS-based access control architecture will allow providers to offer multimedia services while optimizing the use of the underlying network resources. We suggest new concepts and protocols to provide solutions to these challenges and describe the French national research project named MMQoS aiming on building such future networks.
