The UMTS core network was created to support the increasing demand for wireless voice and data traffic. As data usage increases, there is a growing need for operators to be able to understand more detail about data usage patterns in their network. This course provides an overview of the 3GPP core network as it has evolved from UMTS Release 99 through the LTE Evolved Packet Core (Release 8). It explores the 3GPP services architecture (IP Multimedia Subsystem, or IMS) and the various concepts used in IMS architecture, functions, components and interfaces. The course also covers key topics such as PCC, QoS, and interoperability between UMTS and LTE as well as implementation of Femto Cells (Home NodeB), and the emerging area of local internet breakout. We take an end to end view of the network and explain practical implementations of services such as enterprise connectivity, email connectivity, voice using IMS, etc. The course covers various aspects of mobility management for both UMTS and LTE networks.
Learning Objectives
After completing this workshop, the student will be able to: • Sketch the 3GPP Core Network architecture for R99-R8 • Describe key steps in the 3GPP evolution from 2G through 4G • List key features of the 3GPP packet data releases (R99 through R8) • Sketch an end-to-end call and data session setup for UMTS/HSPA • Explain various roaming scenarios and the role of GRX & IPX • Sketch how UMTS/LTE use Ethernet backhaul and IP/MPLS • Sketch how popular data services such as email and private IP access are implemented over UMTS/HSPA networks • Describe UMTS/LTE data mobility in light of 1xEV-DO and WiMAX • Explain the function of key protocols like SIP, BICC, and RTP • Sketch end-to-end IMS-based service call flows for VoIP and SMS • Illustrate how QoS is allocated end-to-end • Illustrate IMS interworking with the PSTN and legacy wireless • Describe the function and application of PCC
