LTE - Signaling & Protocol Analysis
(Vol.1 RAN and UE)

Training Course Description

This training course is a must for everybody who requires a detailed understanding of the protocols and signaling procedures within E-UTRAN and the EPC. In that respect the clear focus of this course is on the protocols of the UE and the E-UTRAN.
The training course starts with a review of the LTE physical layer and the concepts and protocol stacks of E-UTRAN. This part concludes with the review of the EPS network architecture.
Immediately afterwards we jump into real-life call flows and scenarios and confront the student with the look & feel of the LTE protocol suite. This part ends with an assessment of what will be the focus of the following chapters.
The next chapters are dedicated to the different protocols EMM, ESM, MAC, RLC, RRC, S1-AP, X2-AP, SGs-AP and S101-AP.
The training course concludes with the presentation and analysis of LTE signaling flows and real-life call flows.

As in all our training courses, we integrated several interactive exercises for a perfect learning experience.

How do attachment, session establishment and bearer setup work in LTE?
How does a circuit-switched fallback scenario look and which messages are exchanged among which network nodes when and why?
Can I obtain an e2e-scenario that explains how the PCRF authorizes and initiates a dedicated EPS-bearer establishment?
How are the LTE protocol stack entities organized and which channels are established between them?
How do the PDU's of MAC, PLC, PDCP, RRC, S1-AP and the X2-AP look like?
According to which guidelines MAC is scheduling the traffic and how is the flow control in between UE and eNodeB performed?
What are the benefits of multiplexing logical channels on transport blocks and to apply a flexible RLC PDU size?
What new security concepts are applied in PDCP?
What are the key differences of RRC in E-UTRAN vs RRC in UTRAN?
How do we interpret ASN.1 PER encoded call flows like in RRC and in S1-AP?
How the concept of the initial context setup procedure s allowing for a very low control plane latency?
How are system information messages structured and transmitted in LTE?
How is the interworking with cdma2000 embedded and realized in LTE?
What are the mechanisms to create a self-organizing network?
How do the various handover scenarios in LTE work?

Test engineers who need to understand the details of the LTE signaling protocols.
Design staff of handsets and E-UTRAN who requires a deep inside view of the LTE-related protocols.
2^nd and 3^rd level troubleshooters who need to understand the LTE protocol stack in detail.

The student must possess a thorough understanding of LTE and EPS before coming to this course.
We recommend our courses LTE from A-Z and SAE from A-Z to be taken beforehand.
Practical experience with protocol testers and IP-sniffers is necessary.

The student is enabled to understand the concepts of the LTE protocol stack.
The student is able to develop and to test the higher layer protocol stack of LTE.
The student will be enabled to effectively communicate LTE protocol stack issues with his/her peers.
