TRAFFIC DRIVEN CHANNEL RESERVATION SYSTEM FOR HANDOVERS IN CELLULAR NETWORKS

摘要

A method is disclosed for reducing handover failureprobability in cellular networks which includes the steps ofdetermining whether a mobile subscriber is traversing a pre-handover zone defined in each cell of the network, reservinga free channel in an adjacent cell for the mobile subscribertraversing the pre-handover zone, and granting the freechannel to the mobile subscriber upon entering a handoverregion extending across the boundary of the adjacent cellsprovided that a free channel is available at such a time,and in the alternative, if a free channel is not availableat such a time, the handover request is queued until a freechannel becomes available.
