ELP 4004 ★★★★ Public schedule
The course offers a complete understanding of all signalling protocols implemented in the Long Term Evolution (LTE) /System Architecture Evolution (SAE) technology. The course presents the LTE/SAE architecture with its nodes, interfaces and protocol stacks and describes protocols through functions and and services they provide. The course focuses on the details of the radio access network (LTE) signalling, however the most important aspects of the core network (SAE) signalling are also covered. 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.
Target audience – Who should attend and benefit
The course is addressed to network optimisers and technical staff requiring deeper understanding of LTE signalling.
Prerequisites – What you are supposed to know prior to the course
Successful completion of the LTE Air Interface is required.
