LTE / EPS - EPC and EPC Signalling

Course Description

The course “Long Term Evolution/Evolved Packet System with Evolved Packet Core focus” is intended for telecom professionals with the task of implementing the mobile system standards based on 3GPP LTE and more specifically, the Core Network parts. Therefore the focus is set on understanding the LTE system from a mobile operator’s perspective, addressing the implementation issues and challenges of the Core Network engineers.

A thorough system overview of the LTE/EPS (Long Term Evolution / Evolved Packed System) is featured along with all the details on the Network functions, interfaces and network capabilities. Furthermore a number of traffic cases are studied and several comparisons are made to the existing UMTS technology and the inter-working with the UMTS and GSM systems. In addition, network migration and spectrum re-farming strategies are discussed.
