“…It is a common practice to define channel loading in term of the number of mobiles each channel will support in the mean busy hour to give the users a desirable GOS [2]. Thus, the GOS can define as the number of unsuccessful calls relative to the total number of attempted calls [2][3][4]. GOS is a measure of the probability that a percentage of the offered traffic will be blocked or delayed.…”

Abstract: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.

“…The probability of delay calculated according to equation (2) is used in the evaluation of waiting times. For the calculation of mean waiting time of priority and nonpriority calls the relations of Francisco et al [4] are used with N replaced by N-k in the modified relations will be:…”

Abstract:The traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with greater efficiency. The useful parameters to estimate the performance of the system are voice quality, frequency spectrum efficiency and Grade of Service (GOS). The grade of service will be affected due to outage of channels. In this study, a new scheme is proposed to reduce lost calls due to channel outage in the fixed rate outage cellular system. In this proposed scheme the call will never dropped but may be delayed. The system performance is evaluated for different conditions and the results are discussed.
