Course Overview

Course in a Nutshell

If your job requires understanding IMS and LTE and how they work together, this course can help you get there quickly.  The first part of the course covers the basics of LTE, physical layer, control signaling, and RF management.  You will learn the basics of LTE network elements and function, signaling, system acquisition, and basics of mobility management in LTE.  The course then moves onto more advanced topics in LTE such as Quality of Service (QoS) management and scheduling, hand-over. inter-technology handover, power saving modes, VoIP, and session continuity via LTE.  The second part of the course addresses intermediate to advanced IMS issues including: network design and configuration; core network, routing, security, and applications; and IMS interworking within an LTE environment.

 

Customize It!

The course can be extended to five days to include the prerequisite material on UMTS/HSPA and IP (if the audience is unfamiliar with it) or a deeper discussion of LTE and IMS. A shorter, 3 days version that covers the technologies in less detail is also available.

 

Learn How To

  • Plan and engineer for LTE, IMS, and the two of them together
  • Manage legacy services over IMS including 9-1-1 messaging and more
  • Anticipate issues when rolling out new LTE and/or IMS based applications
Audience / Prerequisites

Aimed At

This course is aimed at those who need to understand LTE and IMS and how they work together. This includes RF and network engineers, systems architects, product managers, OSS personnel involved with features and services, management, and support staff who can benefit from a better, juxtaposed understanding of LTE and IMS.

 

Prerequisites

General knowledge of telephony, wireless communications, and IP along, ideally, with some prior exposure to IMS and/or WCDMA through UMTS/HSPA.
