MODELING OF THE HANDOVER DWELL TIME IN CELLULAR MOBILE COMMUNICATIONS-SYSTEMS

In recent years, handover request queueing has been extensively analyz ed as a handover protection scheme for future cellular networks. In th is frame, however, while channel holding time distribution and cell bo undary crossing rate have been modeled, the distribution of the allowe d queue waiting time-i.e., the handover dwell time-has remained an ope n question from the modeling standpoint. In this frame, this paper pro poses a model of the handover dwell time in circular cells coverage. T he agreement between modeling and simulation results is very satisfact ory. A fitting of an asymptotic behavior of the handover dwell-time di stribution with a truncated Gaussian function is also provided, measur ing the fitting goodness in various test cases. The practical insights the model can provide are also outlined in the paper.
