Dynamic IP Tunneling for Next Generation Mobile Networks

The paper describes the principles of a novel mechanism that is aiming at providing unprecedented Quality of Experience (QoE) in next generation mobile networks. The main benefits include: (i) enabling dynamic IP tunnel management (establishing and tearing down) with terminating point in the mobile device instead of the traditional base station; (ii) enabling multiple parallel tunnels (e.g., Generic Routing Encapsulation (GRE)) between an anchor node and a mobile device, where a specific tunnel may support differentiated Quality of Service (QoS) requirements for a targeted service class; (iii) enabling advanced network protocol support for service flows split across multiple Radio Access Technologies (M-RATs), whenever it may be deemed necessary to support and maintain a targeted QoS level per service flow; (iv) allowing to aggregate the necessary bandwidth to meet the QoS requirements per service flow if no single RAT can fulfill them alone; (v) supporting massive M-RAT capacity aggregation for enhanced scalability and very large throughput.
