Abstract
A method is disclosed for reducing handover failure probability in cellular networks which includes the steps of determining whether a mobile subscriber is traversing a pre-handover zone defined in each cell of the network, reserving a free channel in an adjacent cell for the mobile subscriber traversing the pre-handover zone, and granting the free channel to the mobile subscriber upon entering a handover region extending across the boundary of the adjacent cells provided that a free channel is available at such a time, and in the alternative, if a free channel is not available at such a time, the handover request is queued until a free channel becomes available.
