Abstract
A method for operating an SDN-based mobile communication system, which includes a mobile network having a control plane and a data plane, with a network controller being implemented therebetween, includes: providing a control plane function that possesses information from an access network about location and/or proximity of devices and information about rules and/or policies for setting up sessions for the devices; and the network controller, by collaborative operations with the control plane function, selecting one or multiple data plane nodes that are, based on a particular device's request for session establishment, suitable to act as policy enforcement points for enforcing rules in the data plane that are for enabling connectivity for the particular device.
