  Abstract

With the improvement of wireless network technology and the increasing number of subscribers in mobile network, the improvement of performance and the quality of service have become the most important elements. Especially, the reliability of network where the users are moving should be evaluated more importantly than the fixed network. In this paper, we proposed a reliability account for the networks where the communication structure changes frequently. This account applied to the circuit domain in WCDMA network. First, we analyzed state transition rate using Markov Process after the analysis of using graph model. Next, using the total probability, we accounted reliability about each state. Finally, using the proposed account, we accounted whole reliability about the networks with diverse communication structures. This account has an benefit which is the accurate reliability evaluation of the mobile network in spite of its frequent variation in structures and states.
