AAA Diameter

2 Days / 4 Live Online Sessions (0900-1230) / Technical Level: Level 3

Course Code: QS1301

Course Summary

RADIUS is used essentially to introduce the topic and provide a progression towards Diameter with the main emphasis being on the newer Diameter protocol.

The course will also delve into the deployment of Diameter as seen by modern telecoms in particular. After looking at Diameter in detail the course will review how it is being implemented into 3GPP’s IMS and LTE network architectures.

Who would benefit

This course is primarily designed for engineers working for equipment manufacturers and for network operators who are involved in equipment design, manufacturing, network planning, network optimization, strategy determination and deployment of RADIUS and Diameter technologies.


There are no major prerequisites, but to maximise the benefits of this course a good understanding of the architecture of modern telecommunications networks including IMS and LTE would be advantageous as well as a reasonable understanding of the MAP protocol and the messages used to support a mobile device for registration and location updates. A grasp of SCTP as used in SIGTRAN would also be beneficial.
