Essential 4G core protocols and signalling   |    A 3 day training course

4G core protocols and signalling training course description

LTE, Long Term Evolution, as defined in the 3GPP Release 8 through 15 specifications, consists of the eUTRAN and the SAE /EPC. There are a considerable number of protocols and signalling messages being passed during system operation, between Uu and eUTRAN as well as between eUTRAN and EPC. This course describes the overall protocol structure before focussing on specific protocols; including LTE to Ue protocols including PDCP, RRC, RLC and MAC, the inter-eNodeB protocol X2, the S1 protocol between the E-UTRAN and the EPC and the evolved GTP for LTE.

What will you learn
  • Describe the use of the following:
    • S1-AP for Non-Access Stratum Messaging
    • Initial Attach Request message
    • GTP-C between the MME and SGW
  • Describe the use of MME temporary identities.
  • Describe the eNodeB Temporary Radio Identities.
  • Explain support for Quality of Service in LTE/EPC.
  • Explain the use of the SrS interface.
  • Explain the basic operation of VoLTE.
  • Explain dedicated and default EPS bearers.
