89 p. In this thesis, the multidimensional traffic model in a cellular network is studied. The concept of multidimensional traffic model is needed to model the traffic for multiclass of subscribers which are classified by holding time, arrival rate and bandwidth. That model is applied from Narrowband ISDN traffic model in fixed network (circuit swithching mode approach) including traffic due to mobility of subscriber. The system performance is evaluated by discrete event by event simulation model. In this simulation network, hierarchical cell structure (microcell/macrocell) is used to increase the capacity and improve the system performance. In addition, various strategies are applied to improve the system performance as the rearrangement strategy, service protection and handover protection. The rearrangement strategy is used for increasing the utilization of channels by exploiting the intelligence inherence in the system. The service protection is used to guarantee the certain grade of service (GOS) for specific subscribers. The handover protection is used to ensure the handover attempt are not interrupted to forced into termination. The results show the performance measure per cell of different services in term of new call blocking probability, handover failure probability, total carried traffic, forced termination probability A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1996 Cellular radio Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B14977 http://203.159.5.9/ait-thesis/detail.php?q=B14977 180698 20260818223057.0
