The goal of the LTE System Architecture Evolution (SAE) from the 4G/3GPP is to achieve  a high-data-rate, low-latency, packet-optimised system that supports multiple access technologies. Long Term Evolution, as defined in the 4G and 3GPP standards, has described both an evolved Radio Access Network (E-UTRAN) and a new core network strategy termed SAE -  System Architecture Evolution.

The main part of SAE is the Evolved Packet Core (EPC), otherwise known as the SAE Core. The new core network is key to achieving the level of performance that LTE must deliver with the sort of low delay across the network that has been hitherto unachievable with GPRS and UMTS.


Upon completion of this course the delegate will be able to:

  • Describe the components & functions of the SAE
  • Identify the SAE Architecture
  • Explain the role of the Policy & Charging Rules Function (PCRF)
  • Understand the PCC Rules procedure
  • Understand Interworking with other Access methods
  • Describe the Circuit Switched Fallback procedure for voice
  • Understand the use of IMS & VoIP service
  • Understand basic SIP Signalling
  • Explain Packet Filtering
  • Understand the use of GPRS Tunnelling Protocol (GTP)
  • Describe Default EPS Bearer procedures
  • Understand the use of DiffServ
  • Understand Quality of Service (QoS) requirements
