The evaluation of user mobility behavior in personal communication service network

Cellular technology has shown a tremendous impact to communication behavior and human life. The growth of cellular users' increase every year world wide. GSM as the second generation still exist as the famous technology and soon the third generation comes as a competitor. This technology has delivered an opportunity to communicate to anyone, anywhere and anytime wherever the service is available. In terms of services, many network operators have expanded the service coverage to cope with the increased of user density in a certain service area and improved services to enhance quality of service. In this paper, three control mobility schemes of user movement using a certain threshold level are proposed to investigate user mobility behavior. Each of these schemes incorporates equal cell size and examines in similar mobile environment based random mobility model. Every user can move in any direction with equal probability. Based on hexagonal cell model, 49 cells have been developed as a service area for simulation environment. Two mobility characteristics: user distribution and direction are considered as parameters to analyze user behavior in the certain service area. Simulation results using three mobility control schemes: scheme A, scheme B and scheme C; have shown that in time domain analysis. Result shows that the direction of each MS for any implemented scheme is unique. In term of mobility characteristic, we rind that 90% of service area are occupied by MS for both balanced and un-balanced strategies while in cell strategy approach the distribution for all the schemes the result is less that the above strategies in terms of service.
