The evolution of mobile networks from 3GPP R99 to R4 / R5 introduces many changes to existing core
networks, their architecture and operation. It requires engineers to understand the complexity surrounding
these Networks and the associated operations required for the migration towards all IP-based bearer

This course has been designed to provide delegates with a comprehensive understanding of the principles of network signalling, traffic flows associated with the enhanced layered architecture of 3GPP networks, an introduction to Softswitch Solutions, Bearer Independent Call Control and other functions required for the migration towards all IP-based bearer networks.

Each training session is thoroughly reviewed to help delegate understanding, and with the aid of the trainer, delegates will complete comprehensive trace analysis practical sessions to clarify precise signalling flows and operational procedures. Delegates will also be required to complete various signalling flow diagrams.


At the end of the course the delegate will be able to:

  • Explain the evolution of mobile communications networks from GSM (R99) through 3GPP R4 / R5
  • Draw the overall architectures used within R4 / R5 Core Networks and explain their individual
  • Understand the signaling processes and topology architectures for TDM, ATM, IP, SIP and MPLS
  • Explain the comprehensive operation of all protocols used within the SS7 Signaling Network
  • Describe the signaling transport network alternatives used within the 3GPP Core Network - MTP, ATM, IP
  • Understand the signaling protocols associated with call setup - BICC, MGCP (MEGACO), ISUP
  • Describe the signaling flows between MSS nodes (MSC server’s and MGW)
  • Explain the signaling principles and concepts of IPBCP and Q.AAL2
  • Describe the signaling procedure between MGW devices for configuration of ATM and IP bearers
  • Explain SCCP services and routing alternatives used by RANAP, BSSMAP and MAP
  • Identify RANAP and BSSMAP signaling process for a call setup and list important functionality
  • Discuss the role and implantation of SS7 over IP (SIGTRAN) with in 3GPP Networks
  • Understand the comprehensive signaling procedures of call set up and explain how signaling
    protocols interact
