(Vol.1 RAN and UE)

backtotop.gifTraining Course Description

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.

Some of your questions that will be answered

  • 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?

backtotop.gifWho should attend this class?

  • 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.
  • 2nd and 3rd level troubleshooters who need to understand the LTE protocol stack in detail.

backtotop.gifPre-Requisites

  • 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.

backtotop.gifTraining Course Target
