Downlink packet replication to support handover

Abstract:

Techniques are provided for downlink packet replication to support handovers. In one example, downlink packet replication occurs on a fabric node in an S1AP handover scenario. In another example, downlink packet replication occurs on a source Access Point (AP) using a target AP as a secondary AP in an S1AP handover scenario. In yet another example, downlink packet replication occurs on a source AP using packet encapsulation in an S1AP handover scenario. In still another example, downlink packet replication occurs on a source AP in an X2 handover scenario. Similar techniques are provided for any suitable telecommunications/cellular technology.
