LTE and LTE-Advanced is THE global standard for 4G mobile broadband systems. It uses the Evolved Packet Core (EPC) as core network. Higher demands for wireless data and the demand for new type of services drive the continued evolution of wireless networks. A new standard was just defined in the latest 3GPP releases, which is called LTE-Advanced Pro and will pave the way towards future 5G systems. LTE-Advanced Pro addresses complete new markets with new systems for future Internet of Things, Public Safety, Car-to-Car communication, future Broadcast Systems and others such as wearable devices. Besides the radio, also higher layer protocols and the architecture has been enhanced to enable such new services and functions.


Starting from the fundamentals of LTE protocol and the overall EPC architecture, this course provides an overview of the protocol and architecture to support new LTE-Advanced Pro systems. Examples that are explained in detail are Proximity Services (incl. discovery or direct communication), Group Communication Services Enabler required for future LTE based Public Safety Systems as well as new architectures to enable Vehicle to Vehicle Communication with or without Road Side Units. For the two new Machine-to-Machine communication systems, in 3GPP called Machine Type Communication (MTC) and Narrowband Internet of Things (NB-IoT) a new lightweight architecture has been defined. Among others, it allows to send messages via the control plane or to suspend the user plane to minimize the signaling overhead for massive M2M communication. Technologies like network slicing will enable the separation of networks serving different requirements and will also be supported in future 5G networks.
