The major focus of this course is the interworking between UMTS/HSPA and LTE. The course 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. LTE is optimized for the delivery of IP services including VoIP. It can also cooperate with a 2G/3G network to support a Circuit-Switched (CS) call using features such as Single Radio Voice Call Continuity (SRVCC) and CS fallback. The course also previews IP mobility mechanisms, security, and QoS considerations. In summary, the course provides both the architectural features and the detailed message flows of the interworking between LTE and 3GPP 2G/3G.
Learning Objectives
After completing this course, the student will be able to: • Sketch the LTE architecture, including interfaces to GERAN/UTRAN • Describe components/interfaces that make up the LTE core network and their roles in the interworking • List requirements for LTE and 2G/3G interworking • Sketch the interworking architecture of LTE and GERAN/UTRAN • Walk through an LTE session setup • Enumerate the steps involved in idle mode mobility • Walk through the steps of an active mode handover • Discuss the role of IMS in LTE • Define SRVCC and CS fallback
Intended Audience
This course is designed for those involved in the evolution and migration of UMTS/HSPA networks to LTE networks. It is suitable for planners and engineers responsible for network planning, design and deployment, integration and network operations.
