Abstract

See full text

A processor-implemented method, apparatus, and/or computer program product move Open Systems Interconnection (OSI) layer 4 connections between wirelessly-connected user equipment to a series of cell-towers, wherein an OSI layer 4 connection is extracted out of the underlying cellular protocols at the series of cell-towers. A detection is made that user equipment, which has a broken-out layer 4 connection, has moved from a first cell-tower to a second cell-tower. Traffic for an existing layer 4 connection from the user equipment is tunnelled between the first cell-tower and the second cell-tower. A predetermined trigger event is identified. In response to the predetermined trigger event occurring, an ongoing bidirectional flow of data packets is migrated from the user equipment over to layer 4 connections maintained at the second cell-tower.
