Abstract

A mobility event is supported on a flat or next generation mobile data networks with data breakout or offload at the edge of the mobile data network. Packet data is buffered while a complete set of the PDP context information is transferred from the source eNodeB to the target eNodeB and the mobile core network is updated with the information about the handover in a timely manner to prevent packet loss and thus provide a seamless user experience. The breakout system supports the PDP context transfer by shifting the end point of the TCP communication from the local breakout entity (MIOP@eNodeB) to the core breakout entity (MIOP@GW), transferring the TCP connection to the core breakout entity, and supporting the network initiated control flows in a way that is seamless from the perspective of the UE and the core network.
