Optimal prioritization of handovers in mobile cellular networks

Abstract

Investigates channel allocation policies that choose among incoming handover requests to a particular cell. Within a class of non-reserving policies that efficiently utilize the scarce channel resources, the authors identify a most critical first policy that is optimal with respect to handover failure probability. The proof of optimality is accompanied by the description of two techniques to realize the policy in practice. Simulation results that demonstrate its improvement over previous policies are presented as well.
