Description

This course gives a complete overview of the SS7 structure, architecture and evolution, in fixed network and covers parts needed in mobile networks. The course explain all basic concepts and structure of a signaling network and is the starting point for everybody who wishes to work with signaling and implemented protocols in different networks both for fixed and mobile applications.

  

Learning objectives
  • Explain the signaling concepts used in telephony networks
  • Explain the terms Inter-Exchange Signaling, Channel Associated Signaling, CAS,  and Common Channel Signaling, CCS or SS7
  • Explain the relationship between the OSI model and Signaling System No.7, SS7, and the IP protocol suites
  • Explain the basic structure of SS7 and mention the most common application-layer protocols
  • Mention common SS7 network topologies
  • Explain the functions of (Level 2), Link Layer Transactions and (Level 3) MTP.
  • Explain the functions of Signaling Network Testing (SNT) and Management (SNM)
  • List the major functions of the ISDN User Part (ISUP) and TUP (Telephony User Part)
  • Draw the call set-up SS7 signal message flows
  • List the common SS7 messages and describe their functions
  • Explain the principles of routing of SCCP messages and SCCP addressing rules
  • Explain briefly, the SCCP management procedures
  • List the major functions of the Transaction Capabilities Application Part (TCAP)
  • List the main functions of Mobile Application Part, MAP
  • Explain the Intelligent Network (IN) structure and list the functions of the basic IN nodes
  • List the major functions of the IN Application Part and CAMEL Application Part, CAP
  • Briefly explain what is softswitch concept and the protocols needed for its implementation.

   

Target audience

The course is designed for technical staff requiring an understanding of the Signaling System No. 7, SS7, in general and how SS7 is implemented in the core network architecture

    

Prerequisites

The participants should have basic knowledge in telecommunications or data-communications. No previous signaling knowledge is required.

  

Duration and class size

The recommended length of the course is 4 days depending on the participants’ background. The maximum number of participants is 16. However it is easy to adapt the course length to the actual needs, thanks to the modular structure.

 

Learning situation

This course is based on theoretical instructor-led lessons given in a classroom environment.
