Call Admission Control Policy for Integration of Voice/Data Traffic in Cellular Mobile Networks

2nd International Conference on Computational Intelligence Communication Systems and Networks (CICSyN) -- JUL 28-30, 2010 -- Liverpool, ENGLANDIn integrated voice/data cellular mobile networks, the most important consideration is to utilize the resources in an efficient way and maintain the required quality of service (QoS). In this paper, we proposed a new call admission control scheme for improving efficiency of resource utilization. Proposed scheme restricts the new and handoff voice and data calls arrived to system by finding the optimal threshold number of new and handoff voice and data calls allowed in system according to admission criters such as maximum data response time, voice and data blocking and dropping probabilities. From the numerical analysis, we observed that required call-level QoS for both voice and data calls is provided and upper bound of data response time is guaranteed to data calls. Also taking the required minimum bandwith need of voice calls in different values, we evaluated the performance improvements of data calls.IEEE, IEEE Comp Soc, UKSim, Univ Liverpool, Asia Modelling & Simulat Soc (AMSS), UK Simulat Soc, IEEE UK & RI Comp Chapter, European Simulat Council (EUROSIM), European Council Modelling & Simulat (ECMS), Univ Technol Malaysia (UTM), Univ Sci Malaysia (USM), Univ Malaysia Sabah (UMS), Univ Technol Mara (UiTM), Machine Intelligence Res Labs (MIR Labs), Norway Univ Sci & Technol, Nottingham Trent Uni
