LTE RAN Signaling and Operations for GSM/UMTS Operators *NEW*

In the wireless landscape, one of the next generation wireless networks is known as Long Term Evolution (LTE). LTE promises dramatic improvements in throughput and latency, which opens a new era in the Quality of Service (QoS). These enhancements are based on several fundamental pillars: a new air interface (OFDM+MIMO), simplified network architecture and efficient air interface structure and signaling mechanisms. This course takes a detailed look at the layer 2 and 3 signaling procedures. The main focus is on UE-E-UTRAN and UE-EPC signaling. The course also provides an overview of the end-to-end call setup scenario involving the IMS components of the core network. This course includes message walk-throughs and associated exercises to facilitate in-depth understanding of LTE radio network operations.

Learning Objectives

After completing this course, the student will be able to:
• Sketch the network architecture of the LTE E-UTRAN and EPC
• List and describe the use of DL and UL channels of LTE
• Step through the system acquisition process in LTE
• Illustrate initial Attach operation including security and IP address assignment
• Explain the implementation and enforcement of QoS for calls such as VoIP
• Summarize traffic operations for UL and DL
• Describe various handover scenarios and the associated signaling procedures
• Describe inter-system handover mechanisms, in particular the LTE to 3G/2G scenario
• Compare the LTE radio operations with 2G GPRS and 3G UMTS

Intended Audience

This course is primarily intended for a technical audience in RF engineering, systems engineering, network engineering, support, operations, and anyone seeking a more in depth understanding of LTE signaling details.
