Diameter in Mobilfunknetzen

Course description (english, PDF)

Duration: 3 days

Diameter is the successor to RADIUS and the current AAA (Authentication / Authorization / Accounting) protocol used in many telecommunication environments like IMS and SAE. Especially its highly flexible approach, real-time credit-control, and the additional support of various interfaces make it the preferred AAA solution in today’s mobile networks. It is used on a variety of interfaces for numerous functions like subscriber/location information transport, negotiation of bearer establishment or charging.

Within this course you get a good understanding of the Diameter protocol and its application in mobile networks. The focus is mainly on LTE/SAE and IMS.

Target Group

The course is addressed to technical staff to get a good overview about the DIAMETER protocol and its use in mobile networks.
