摘要:	The integration of voice and data services over PACS systems using a movable boundary scheme is studied. First, we use the theory of discrete-time Markov chain to analyse the system; then, an approximate analysis using the continuous-time Markov chain model is conducted. For the initial access of voice calls we consider two distinct schemes: at most one idle slot being marked available, and all the idle slots being marked available. Numerical results show that the performance difference for voice calls between both schemes is trivial, but the former scheme offers a performance advantage for data calls over the latter scheme. Besides, the performance obtained by the continuous-time Markov model is very close to that obtained by the discrete-time Markov model. This finding suggests the effectiveness of the usage of the continuous-time Markov model, which can dramatically simplify the analysis.
