ENG-513 4G Core Network


*This course is also available as a live distance learning course*

The 4G Core Network, while built on the 3G UMTS (Universal Mobile Telecommunication System) service architecture, emerged through work at the 3GPP (3rd Generation Partnership Project – the mobile platform Standards Body) in an advanced versatile platform capable of processing large amounts of data more efficiently than earlier generations of cellular networks. This 3-day Training Course includes a detailed analysis of the architecture, interfaces, protocols, QoS, deployment and dimensioning of the EPC which supports higher throughput, lower latency, and mobility between 3GPP and non-3GPP radio access technologies.

Learning Outcomes

At the end of the course, participants will be able to:

  • Describe the architecture and interfaces between the E-UTRAN (the 4G air interface) and the EPC
  • Characterize the performance capabilities of 4G SAE platform
  • Discuss the different services carried by the Evolved Packet System (EPS) and their impact on traffic and signaling
  • Outline the key protocols used for control and user traffic
  • Explain the procedure for EPS bearer establishment and service data flow
  • Explain options for carrying voice in 4G, including VoLTE, CSFB, SVLTE, OTT
