To research the call admission control in mobile communication system, a suitable stochastic service model is essential. The self-adaptive technology and the existence of multi-service in OFDMA system make the demand for stochastic service model stricter. This paper builds and analyzes the Petri net models of call admission control in multi-service OFDMA system. And then through analysis of corresponding Markov models and mathematical calculation, the validity of the Petri Net models is demonstrated.
