• 論文抄録 / 内容記述: In actual mobile communication networks the distribution of users' locationsin a service area is not uniform.In the daytime they are concentrated in specific cells that coverbusiness areas and at night they are concentratedin cells that cover residential areas.The users' locations the number of mobile communication users and their behavior change depending on the time zone.This dependency affects the cell traffic; thus the allocation of Base Stations (BSs) in the service areais an important problem to be investigated.In this paper we propose a new modelfor allocation of BSs in mobile communication networks taking account of user distribution user movement channel occupancy and handover.On the basis of this model we developed a simulation systemand carried out many simulationsto evaluate the system performance.Our system uses a queuing modelwith many service stations and customersidentified by their locations.For simulations we consider the actuallocation of road network and the population distributionin Yamagata City Japan.By using the simulation system we can generate various networkswith different patterns of BS allocationsand evaluate the networks' performance.In this paper we consider only the JapanesePersonal Handy-phone System (PHS).However the same model can easily be applied tolarge scale mobile networks.We carried out many simulations for various numbers ofBSs various numbers of channels in a BS and various allocations of BSs.The performance evaluation based on the simulations showsthat the cell size is an important factor in the efficiency of mobile communication networks especially in starting a new business.Various BS allocation scenarios show that a trade-off exists between the users' Quality of Service (QoS) and the size of the area covered.
