A major criterion in evaluating a cellular system is the handover failure probability the probability that a mobile call in progress will be forced to abort during a handover because it could not be allocated a radio channel in the new cell. One factor that influences the handover failure probability is the channel allocation policy within each cell. This policy is used to determine how to allocate the limited set of available channels in the cell to two kinds of calls: new calls originating within the cell, and handovers that migrate into the cell from neighboring cells. Two classes of such policies are explored in this paper's nonreserving and reservation-based. Nonreserving policies do not set aside resources for exclusive use by handover calls, whereas reservation-based policies do reserve resources. For the former class, this paper presents an optimal policy and, for the latter, an adaptive traffic-driven reservation policy that improves on static guard channel policies. Analytic and simulation results are provided for policies in each class.
