[NWV_705] Mobile CSP Network Architecture and Operations

Printer-friendly PDF version

Communication Service Providers (CSPs) are on the cusp of a multitude of network and business transformation choices. This session is designed to provide a good technical understanding of the current CSP network architecture and operations with focus on 4G LTE mobile networks as mobile CSPs are at the forefront of this transformation. The session starts with an end-to-end 4G LTE network architecture including RAN, EPC, Backhaul, Backbone (IP/MPLS) and services networks (IMS/legacy service). We then cover end-to-end LTE session set up and mobility scenarios to show practical implementation not just the 3GPP standards based operations. We follow this discussion on various IMS/VoLTE/RCS scenarios including registration and session setup, interworking with legacy, E911, CSFB, eCSFB, and eSRVCC.

Learning Objectives

After completing this course, the student will be able to:
• Communicate effectively with CSP network personnel
• Articulate the complexity of current CSP networks in Access, Core, Transport and Services areas
• Sketch practical 4GLTE network architecture
• Sketch practical enterprise Ethernet access and IP VPN services architecture
• Sketch end-to-end LTE session setup
­ - Mobile originated and mobile terminated
• Discuss different mobility scenarios
­ - RAN, EPC, service level mobility
• Illustrate various VoLTE scenarios
­ - VoLTE to VoLTE
­ - VoLTE to PSTN
­ - Mobility between VoLTE and non-VoLTE

Intended Audience

This is a technical course, primarily intended for a technical audience requiring a technical introduction to the architecture of a Mobile CSP.

Suggested Prerequisites

• [NWV_104] Welcome to Mobile CSP Network Transformation (eLearning)
