Abstract
This paper discusses long term architectural evolution options of the 3GPP Evolved Packet Core (EPC). It is focused to the question which functions of the existing EPC are addressed or impacted when introducing Software Defined Networking (SDN). Several aspects are discussed showing the benefits of a strict separation of mobile specific gateway functions from SDN functions. In that aspect the suggestions made in this paper differs from existing SDN based concepts. This paper analyses how the SGW/PGWs of the EPC can be decomposed in different ways. A reduction of mobile specific network elements and a separation into network independent administrative domains may help to reduce the cost for network operation in future.
