Improved Performance of Traffic Dependent Outage Rate Cellular System

The designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and interruptions due to the outage channels is tested in the traffic dependent outage rate wireless cellular system. In this scheme no call is dropped but could be delayed. The performance parameters considered for this study is the probability of delay and the mean waiting time for priority and nonpriority calls for non-preemptive type. The system is evaluated for different conditions and the results are discussed.
