Handover Forking Support for Improving Handover Success Rate in LTE
Abstract:
A method, system and computer-readable media are presented for providing forked handover. In one embodiment a method includes building, by a HetNet Gateway (HNG), a cache of all neighbors of a source cell; organizing a list of cells, the list including an original target cell and at least one additional target cell; when a handover determination is to be made, determining the most probable additional cells where a User Equipment (UE) may land if it does not go to the original target cell; duplicating, by the HNG, indirect forwarding data packets coming in from the UE and sending the packets to all additional target cells; and canceling, by the HNG, handovers from all cells other than the target cell target which catches the UE.
