Overview of LTE & GSM/UMTS Interworking


This course provides a comprehensive overview and a technical introduction to LTE & GSM/UMTS Interworking in 3GPP. The course basically begins with an overview of the 4G-LTE and 3GPP 2G/3G network architectures and various associated interfaces. The requirement for interworking is then discussed in detail, including the various building blocks that support interworking in 4G-LTE/ 3G-UMTS/ 2G-GSM networks. This course also covers important topics like Idle Mode Interworking and Connected mode Interworking between LTE, UMTS & GSM technologies.

It is most suited for engineers in network planning and design, product design and development, network deployment, network performance, and network operations. LTE & GSM/UMTS Interworking course helps the students to analyze the key differences between UMTS and LTE architecture, explain the two architectural options for interworking with 3G/2G networks, explain the measurement procedure as it applies to Inter-RAT handover, describe Idle mode activities in LTE, UMTS and GSM/GPRS, illustrate the details of the inter-RAT cell reselection procedure, walk through Tracking area update procedures etc.
