Nos futuros sistemas de comunicações móveis, a ligação directa pode ser limitante porque os serviços de dados emergentes provavelmente exigirão taxas de dados mais elevadas na ligação directa do que na ligação inversa. Neste artigo, derivamos a capacidade Erlang conjunta de um link direto DS/CDMA em termos de probabilidade de interrupção e probabilidade de bloqueio para cada tipo de tráfego em um ambiente de tráfego misto. O algoritmo de compartilhamento de recursos e o modelo Erlang generalizado são empregados para derivar a capacidade Erlang conjunta do sistema DS/CDMA com vários tipos de tráfego. A capacidade conjunta de Erlang que reflete a probabilidade de interrupção e a probabilidade de bloqueio de cada tipo de tráfego é obtida por uma abordagem baseada na perspectiva de comutação de circuitos virtuais. Levamos em consideração o efeito do controle de potência em malha fechada na análise. A partir dos resultados numéricos, confirma-se que a probabilidade de bloqueio como parâmetro de QoS (qualidade de serviço) tem um impacto significativo na capacidade do link direto. Os resultados deste artigo podem ser aplicados ao projeto de sistemas DS/CDMA que suportam tráfego multimídia sem fio.

Abstract: In future mobile communication systems, forward link may be a limiting one because emerging data services are likely to require higher data rates in the forward link than in the reverse link. In this paper, we derive joint Erlang capacity of a DS/CDMA forward link in terms of both outage probability and blocking probability for each type of traffic in a mixed traffic environment. Resource sharing algorithm and generalized Erlang model are employed to derive joint Erlang capacity of the DS/CDMA system with various types of traffics. The joint Erlang capacity reflecting both outage probability and blocking probability of each type of traffic is obtained by an approach based on virtual circuit switching perspective. We take into account effect of closed loop power control in the analysis. From numerical results, it is confirmed that blocking probability as a QoS (quality of service) parameter has a significant impact on the forward link capacity. The results of this paper can be applied to design of the DS/CDMA systems supporting wireless multimedia traffics.
