Course Objectives

The course offers a complete understanding of all signalling protocols implemented in the Long Term Evolution (LTE) / System Architecture Evolution (SAE) technology. It presents the LTE/SAE architecture with its nodes, interfaces and protocol stacks and describes protocols through functions and services they provide. It focuses on the details of the radio access network (LTE) signalling, however the most important aspects of the core network (SAE) signalling are also discussed. Most important network procedures, such as signalling connection establishment, attach, service request and handover are discussed and presented on signalling diagrams. The course is based on the 3GPP Technical Specifications and hence is equipment vendor independent.
