Os futuros sistemas celulares estão previstos para suportar tráfego misto e, em última análise, serviços multimídia. No entanto, uma mistura de voz e dados requer novos mecanismos de serviço que possam garantir a qualidade do serviço. Para transferir dados em alta velocidade, a alocação de canais multislot é vista como uma solução preferida para os sistemas atuais, com o menor comprometimento dos serviços de comutação de circuitos. Este artigo avalia o desempenho de chamadas de voz em banda estreita e transmissão de pacotes de dados multislot em tais sistemas integrados usando uma abordagem analítica de matriz. Este método alcança convergência quadrática em comparação com os métodos espectrais convencionais. A mobilidade também é considerada em um ambiente celular priorizado, onde transferências frequentes têm o potencial de degradar o desempenho dos dados. A distribuição de chamadas de voz, a taxa de transferência de pacotes de dados, o atraso e a distribuição do tempo de espera são derivados. Além disso, um novo algoritmo de controle distribuído baseado em prioridades múltiplas e um esquema de controle de taxa de voz são aplicados para mitigar o congestionamento de filas de pacotes de dados. Os resultados numéricos derivados deste estudo mostram que pacotes de dados maiores incorrem em latência mais longa e o uso destes esquemas flexíveis pode melhorar o desempenho geral.

Abstract: Future cellular systems are envisioned to support mixed traffic, and ultimately multimedia services. However, a mixture of voice and data requires novel service mechanisms that can guarantee quality of service. In order to transfer high-speed data, multislot channel allocation is seen as a favoured solution to the present systems with the least compromise to circuit- switched services. This paper evaluates the performance of narrowband voice calls and multislot data packet transmission in such integrated systems by using a matrix-analytic approach. This method achieves quadratic convergence compared to the conventional spectral methods. Mobility is also considered in a prioritized cellular environment where frequent handoff has the potential of degrading data performance. The voice call distribution, data packets throughput, delay and waiting time distribution are derived. Moreover, a new multiple priority-based distributed control algorithm and a voice rate control scheme are enforced to mitigate the queuing congestion of data packets. The numerical results derived from this study show that larger data packets incur longer latency and the use of these flexible schemes can improve the overall performance.
