Reuse Partitioning has been recently proposed as an effective inter-cell interference mitigation strategy for OFDMA cellular networks. However, mobility of users has been largely ignored in the system level analysis of these systems. To fill this void, in this paper, a teletraffic analysis of a Reuse Partitioning (RP) system is conducted in order to evaluate the impact of mobility on the performance of this kind of systems. Contrary to the previous related published works, in the present paper the analysis considers realistic users' mobility conditions by means of a smooth random mobility model. Also, intra-cell handoff attempts from outside region to inside region are considered. Novel mathematical expressions for the new call blocking, handoff failure, and call forced termination probabilities are then derived. In addition, Multiple Fractional Channel Reservation is used as a prioritization scheme in order to maximize system capacity. Moreover, the best distribution of resources for each region within a cell is also found for different Radio Resource Management (RRM) strategies and mobility scenarios. |
