Optimized low mobility support in massive mobile broadband evolved packet core architecture

With the deployment of new wireless connected devices like sensors and actuators for metering, automotive, healthcare, tracing etc. the wireless core network has to support a new level of scalability for all its functionality, including the mobility management. Being designed for human communication only, the current network architecture ensures seamless mobility in all network locations for all devices being highly redundant for low mobile devices which are rarely and in reduced areas or never moving. This paper introduces a new low mobility management concept based on subscriber device differentiation and differentiated forwarding mechanisms, along with its integration with the current functionality through dynamic management parameters updates. Furthermore, the concept is exemplified on the 3GPP Evolved Packet Core architecture and evaluated as a testbed realization based on the Fraunhofer OpenEPC testbed.
