Summary :

In this paper, we focus on the evaluation of the Erlang capacity for multimedia DS-CDMA systems supporting the multi-class services with different transmission rates, bit error rates, traffic activity factors in the reverse link. The number of concurrent users of the corresponding service group is modeled as a K-dimension Markov chain. Then, the Erlang capacity for the multimedia system can be found based on a K-dimension M/M/m loss system. For an IS-95 type DS-CDMA system, supporting voice/data services, the capacity bounds are depicted in conjunction with the 2-dimensional Markov chain. Furthermore, it is observed that the Erlang capacity with respect to the each service group should be balanced to enhance the total system Erlang capacity. Finally, the channel reservation scheme is considered to increase the total system Erlang capacity.
