INAP and CAMEL Training

The goal of the Intelligent Network (IN) concept was to decouple services and features from the switches themselves - that is seperate service intelligence from the switching functions. This was to allow network operators to be able to develop and deploy services and features independently of the switch vendors, allowing more versatility in service development, simplified rollout, reduced costs and greater autonomy.

To this end the Intelligent Network Application Protocol (INAP) was developed for fixed line networks. INAP is the primary protocol used for fixed line IN outside of North America.

Customised Applications for Mobile Enhanced Logic (CAMEL) provides standardised intelligent network capabilities for GSM networks. It was based upon core INAP with modifications to take into account subscriber mobility.

Training Method

  • Lectures
  • Exercises
  • Demonstrations
  • Training documentation
  • Windows®based software for protocol analysis. SS7/C7 log files will be studied that will be distributed in electronic format. It may be beneficial if participants bring notebooks with Windows 98/NT/2000/ME.

course details

  • Duration: Two Days
  • Language: English
  • Documentation: English
  • Participants: Generally class of five to ten

Prerequisites

The course assumes that the delegates have some familiarity with signalling system #7 (SS7/C7) and basic telecommunication concepts. It is recommended that previous attendance at the 5-Day SS7/C7 to Binary Level (course code SS7-B) has been made, although this is not compulsory.

who should attend

  • Those requiring an understanding of how value added services can be provided within modern telecommunication networks using the Intelligent Network concept
  • Those requiring knowledge of how value added services can be implemented within wireline networks in accordance with the Intelligent Network and INAP framework
  • Those requiring knowledge of how value added services can be implemented within cellular networks in accordance with the Intelligent Network and CAMEL framework
  • Engineers, who are involved in Intelligent Network services design and testing
  • Non-engineers requiring a technical appreciation of wireless/wireless intelligent networking

Presenter Details

The course is delivered by Lee S Dryburgh lead author of Signaling System No. 7 (SS7/C7): Protocol, Architecture, and Services (Networking Technology).
