Description

The complexity of the Core Network and the call control signaling has increased with the introduction of Softswitch Solutions, Bearer Independent Call Control and options for IP-based transmission.

This course is designed to give the participant an overview of signaling technologies and protocols used to manage and control voice calls in in the Core Networks. The theoretical background will provide a better understanding for the Core Network in general and signaling in specific.

 

Learning objectives

On completion of this course the participants will be able to:

  • Explain the basic structure and terminology of the Signaling System No. 7.
  • Explain three different signaling transport alternatives used in the Core Network (MTP, SAAL and SIGTRAN) and list the main differences between them.
  • List the user plane protocol stacks in the Core Network.
  • Explain ISUP signaling capabilities briefly, and list the messages of a typical call setup.
  • Explain BICC & GCP signaling principles and concepts.
  • Explain the signaling between MSCs (also MSC server to MGW) for setting up and releasing calls in the Mobile Softswitch Solution.
  • Explain Q2630 signaling principles and concepts
  • Explain IPBCP signaling principles and concepts
  • Explain the signaling between MGWs for setting up and releasing bearers in ATM and IP backbone networks.
  • Explain SCCP services and routing alternatives used by BSSAP and MAP.
  • Explain TCAP and MAP signaling principles on high level.
  • Shortly describe BSSAP signaling for a call setup and list important BSSAP functions.
  • Shortly describe RANAP signaling
  • Explain the steps in a typical call set up and explain how the involved signaling protocols interact

  

Target audience

The course is designed for technical staff, Core Network Engineers and Core Network Specialists that need to know how SS7 is implemented in a Softswitch solution and what other protocols are implemented in a Core in network architecture.

   

Prerequisites

The participants should have successfully completed the following courses:

“GSM Basics”, “WCDMA Basics”, “SS7 Signaling” or equivalent knowledge.

  

Duration and class size

The recommended length of the course is 5 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.
