Abstract
A TCP context is transferred to a Gi Optimizer to provide cooperative mobility management in a mobile data network with a breakout system. The breakout system includes an Iub Optimizer at the MIOP@NodeB, and the Gi Optimizer at the MIOP@Core. When a MIOP@NodeB detects a mobility event for a broken out user equipment (UE), the Iub optimizer in the MIOP@NodeB coordinates with the Gi optimizer to transfer the TCP/UDP connection established between the UE and the IuB Optimizer to the Gi Optimizer. After the transfer, the UE is served by the Gi Optimizer. The transfer of the TCP/UDP connection to the Gi optimizer may require tunnel stitching at the MIOP@RNC depending on the PDP context state and the RRC state of the UE.
