Title: SPLITTING OF USER PLANE IN MOBILE NETWORKS
Abstract:
A system, methods, nodes and computer program for splitting a user plane in a mobile communication network into an Evolved Packet Core, EPC, processing path (150) and a Software Defined Network, SDN, processing path (140), is described. The EPC processing path (150) is controlled by an EPC control plane (110) and the SDN processing path (140) is controlled by an SDN controller (100). The SDN controller (100) is coupled via a controlling interface to a EPC user plane coordinator (120). The method comprises the EPC control plane (110) causing the EPC user plane coordinator (120) to determine whether to apply the EPC processing path (150) or the SDN processing path (140) to a user equipment, UE, user plane. The method further comprises the EPC user plane coordinator (120) causing via the controlling interface the SDN controller (100) to route the UE user plane in accordance with a result of the determination, taking the determined processing path.
