A Mobile Communication Simulation System for Urban Space with User Behavior Scenarios

We present herein a simulation system to model mobile user behavior in urban spaces covering roads, railways, stations and traffic signals. The proposed simulation system was developed in order to provide analysis in situations that cannot be dealt with analytically, such as mobile users moving along roads and the arrival or departure on commuter trains of group users at stations. In the present paper we observe mobile traffic, which changes with the user distribution, in order to discuss base station location policies. The proposed simulation system can deal with these user behaviors in actual urban space with roads, crossings and stations. The movement of mobile users and the effects thereof on the performance of the mobile system are examined with respect to service quality, such as call loss probability (C.L.P). Using the proposed simulation system, we observe and compare several cell location patterns and discuss the influence of retrial calls.
