4G LTE Evolved Packet Core (EPC) Network Etisalat Academy
  • Locations: Dubai
  • Duration: 2 Days

Course details

The LTE Service Architecture Evolution (SAE) Evolved Packet Core (EPC) network is an essential component of next generation mobile networks. This course provides a detailed analysis of the architecture, interfaces, protocols, QoS, deployment and dimensioning of EPC. The overall requirements of the LTE/SAE proposal are examined, and participants will be able to dimension for the required number of MMEs, SGWs, PGWs, HSS and PCRF for EPC. 

Course Objectives:

  • Outline the architecture and interfaces of E-EUTRAN and the EPC
  • Characterize the performance capabilities of LTE/SAE system
  • Discuss the different services offered by 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
  • Explore options for implementing voice in LTE (VoLTE, CSFB, OTT)
  • Step through the planning methodology for EPC
  • Understand traffic concepts and traffic modeling for LTE
  • Estimate the signaling and user plane traffic
  • Dimension a sample LTE core network, with an estimation of the EPC nodes
