Enhanced UMTS Micro-Celular Multi-Service Planning Optimisation in Business City Centres

Publication . Franco, Cátia; Rei, Ricardo; Velez, Fernando José

Optimisation of the cellular planning process for multi-service Enhanced UMTS in business city centre environments is addressed by using results for system capacity as an input for a cost/revenue function. Based in a definition of simulations scenarios, traffic behaviour, and Quality of Service aspects, a System Level Simulator is used for obtaining system capacity results in the business city centre scenario when overload conditions are considered. Optimum values of the cell coverage distance that maximise the profit per unit length were found. For prices of 5 and 7 Euro cents/MB, optimum values of 80 and 150 % occur around 240m, respectively.

QoS Metrics for Cross-Layer Design and Network Planning for B3G Systems

Publication . Anastácio, Nuno; Merca, Francisco; Cabral, Orlando Manuel Brito; Velez, Fernando J.

After 3G mobile and wireless systems take-up, the research community is now directing its interest towards unified ways of looking at system design, optimization, and quality of service (QoS) issues to satisfy the requirements of next generation multi-service mobile and wireless IP-based networks. Their implementation requires the development of IP QoS architecture and mechanisms encompassing the various layer of the OSI Model to cope with the new requirements. This work identifies the requirements on latency (link radio), latency (end-to-end), bit error rate, data rates, and traffic characterisation for mobile multimedia network beyond 3G. Characterisation parameters were identified and values were suggested for their range of variation, in the context of cross-layer design.

Modelling and Simulation of Multi-Rate Multi-Service Traffic in the Presence of Mobility

Publication . Juarez, Jesus M.; Paulo, Rui R.; San Jose, Eva; Velez, Fernando J.

A multi-service traffic model is proposed, and its validation is achieved by using event-based simulation results. In the single-service case, theoretical and experimental results for ON-OFF blocking probability are close to each other, and there is an almost perfect concordance between theoretical and simulation values when the average sojourn time in cells is equal to the average holding time. In the multi-service case, the behaviour is not exactly the same but a coherent behaviour is achieved for an average traffic per user up to 0.10 Erl.

Enhanced UMTS Cellular Planning for Multiple Traffic Classes in Offices Scenarios

Publication . Cabral, Orlando Manuel Brito; Velez, Fernando J.; Hadjipollas, George; Stylianou, Marinos; Antoniou, Josephine; Vassiliou, Vasilis; Pitsillides, Andreas

It is shown that enhanced UMTS is an affordable solution for providing the required network quality and to reduce infrastructure investments in offices scenarios. System capacity results are obtained by using a system level simulator which considers traffic characterisation parameters and services usage in detail, among other. Results for the most profitable cell radius are obtained via an optimisation procedure based in economic aspects. A higher number of pico cells (with a smaller radius, around 30-32 m) can be installed in the future, when costs of deploying and maintaining the network decreases, allowing for supporting higher system capacity, and reducing prices. Our approach is based in a detailed services analysis, which represents a worst case situation relatively to the total services approach, because the later does not discriminate results for the different traffic classes. The impact of call blocking, handover failure, end-to-end delay, and delay variation are taken into account.

Enhanced UMTS Simulation-based Cellular Planning in Urban Scenarios

Publication . Cabral, Orlando Manuel Brito; Velez, Fernando José; Franco, Cátia; Rei, Ricardo

Aspects of cellular planning for E-UMTS (Enhanced UMTS) are addressed, and results for system capacity are obtained, as a function of the coverage distance. E-UMTS traffic generation and activity models are described and characterised, based on population and service penetration values. An urban scenario was defined with a selection of relevant multi-rate bursty applications. By using a System Level Simulator results were obtained for the end-to-end delay, and for blocking and handover failure probabilities. By using these results, models for the supported fraction of active users and throughput were obtained, as a function of the cell coverage distance. When the coverage distance decreases from 600 to ~200 m, the supported throughput per km2 increases from ~1Mb/s to ~5 Mb/s. By using trisectorial antennas with one amplifier a maximum throughput per BS of 600kb/s was obtained.
