Abstract: Each UE in a mobile data network is assigned two different addresses, one a common IP address used downstream of the P-GW and the other a new IP address used upstream with the router and unique to the data processing node. The node changes the IP address of the UE in either direction as a packet passes through the P-GW. The use of an IP range unique to each node or data processing unit allows the upstream router to route downlink packets directly to the node containing the UE context, so that forwarding of packets between nodes is greatly reduced, if not eliminated. By getting rid of this inter-node forwarding, the data plane can scale to much greater limits.

Abstract: A system and method in a packet network for optimally separating control and data in the context of mobile networking. The embodiments disclosed herein utilize virtualization and elastic computing in the context of a control plane while the user plane flexibility is realized by application programming interfaces (APIs) between a control and user plane. The control plane is configured to receive a notification that a mobile device is done sending or receiving a communication; store in a flow table flow information associated with the communication; receive a trigger for resumption of flow when the communication is to be resumed; and pass the flow information to a cache in a data plane.
