[LTE_420] LTE RAN Signaling and Operations: Part 3 - Interworking (GSM/UMTS)

Printer-friendly PDF version

The major focus of this course is the interworking between UMTS/HSPA and LTE and begins with a brief overview of LTE and 3GPP 2G/3G network architectures and requirements for interworking. The building blocks that support interworking between LTE and UMTS/HSPA are discussed in detail, including the new interfaces, hybrid device capabilities, and radio/core network mechanisms. Different interworking/mobility scenarios are listed and detailed message flows are given. The course also previews IP mobility mechanisms, security, and QoS considerations. The course provides both the architectural features and the detailed message flows of the interworking between LTE and 3GPP 2G/3G. In summary, this course provides a comprehensive overview of LTE technology Interworking with other 3GPP networks.

Learning Objectives

After completing this course, the student will be able to:
• Analyze the key differences between UMTS and LTE architecture
• Explain the two architectural options for interworking with 3G/2G networks
• Sketch the network interfaces and protocols used for interworking
• Explain the measurement procedure as it applies to Inter RAT handover
• List the measurement events for E-UTRAN, UTRAN and GERAN
• Examine the detailed call flows for the inter-RAT procedures between LTE and UMTS/GPRS
• Describe Idle mode activities in LTE, UMTS and GSM/GPRS
• Illustrate the details of the inter-RAT cell reselection procedure
• List key broadcast information parameters needed for idle-mode cell reselection in all 3 RATs
• Walk through Tracking area update procedures
• Explain the combined TA/LA update procedures

Intended Audience

This course provides a comprehensive overview and a technical introduction to LTE Interworking with 3GPP networks. It is suitable for engineers in network planning and design, product design and development, network deployment, network performance, and network operations.
