Description: Customized Applications for Mobile network Enhanced Logic (CAMEL) is a standard for intelligent GSM-based mobile networks.  Deployed worldwide, CAMEL enables mobile network operators to offer value-added services quickly and efficiently whether in their home network or roaming.  CAMEL is defined by the 3GPP in four different phases.

Exercises are provided throughout the course, reinforcing a practical understanding of the material.  This gives the student practice in analyzing the protocol and understanding how the data being sent and received is used.

What You Will Learn

This course will examine the key concepts and terms of Intelligent Networking (IN) in general and CAMEL in particular.  The course starts with an overview of GSM followed by GSM signaling.  From there we will define Intelligent Networking and the various phases of CAMEL.  Emphasis is placed on the standards that define CAMEL and the messages.  There is opportunity throughout the class to further understand the material through practical exercises.

Who Will Benefit From This Course

This course is designed for individuals responsible for or involved with network planning, switch maintenance, central office engineering, interconnection, technical support or network operations.  Though this course is designed for wireless providers, those involved in the wireline interconnect area might also find it beneficial.
Course Prerequisites:  A basic knowledge of mobile telephony and signaling would be helpful, but not essential.
