Abstract

Minimization of the forced termination probability of active connections during handoff is one of the most important tasks for seamless cellular network operation. Handoff delay minimization is in parallel with this task. The paper introduces a new dynamic SLA management procedure to be used in cellular DiffServ networks. With the expected visitor list (EVL) processor deployment at base stations in the shadow cluster and pre-messaging among them, virtual call admission control for the incoming mobile is performed in advance. No pre-reservation is performed, and the EVL processing results are stored and kept updated to achieve minimized handoff latency. The efficiency and performance of the proposal have been explored via simulation experiments under different scenarios.
