Learn Voice, Packet & EPC Core Networks in 2G, 3G & 4G-LTE

This course will provide an introduction to Mobile Core Networks that have changed our lives during the recent four decades and will become an essential and inseparable part of human life. First basic concepts of cellular communication systems are discussed, then we describe how they are applied in actual 2G, 3G, 4G and 5G Systems. The emphasis is on the essential concept delivery to non-major learners in the easiest way.

Mastering the core Networks in wireless communications can get you a job in telecom companies and if you already have one it will help you to move ahead in your career, increase your earning potential and add value to any organization.

This course is designed to provide students with in-depth information regarding Core Network architecture. The course has been designed for all levels and starts off by providing the introduction to Core Split Architecture and its advantages over legacy technologies.

During the lectures, all concepts are introduced by means of intuitive diagrams and real-network examples whenever possible.

The Course is divided into 3 main parts:

1st Part: Mobile CS Voice Core Concepts in 2G GSM, 3G UMTS & 4G-LTE (CSFB)

This part focuses on the legacy core Networks used in 2G GSM & 3G UMTS & 4G (CSFB).

In brief it talks mainly about the CS Core Networks which are used in Voice calls & SMS in legacy networks.

2nd Part: Mobile Packet Switching Core Networks

In this part you will Learn Basics & Essentials of Packet Core Networks in Telecom Field ( PS Packet Switching in 2G GSM, 3G UMTS )

This part is designed for who ever interested in packet Data Core Networks ( PS Packet Switching )

The Course will contain every thing related to the Packet Data Networks in 2G, 3G.

3rd Part: 4G LTE EPC, E-UTRAN Concepts, Architecture & call flows

This part aims to provide a concise synopsis of how LTE EPC operates, focusing on the driving factors behind LTE EPC, as well as the architectural view of an LTE EPC & E-UTRAN deployment. Operational procedures such as network attach and bearer utilization will be examined, as well as key mobility and roaming considerations. Finally, LTE voice solutions will be highlighted, with focus on CSFB and VoLTE.

Course Duration

This course is around 16 Hours duration.
