Diameter Routing for LTE
3 days  (Instructor Led Online)  |  LTE (Insoft Specials)

Course Details

The Diameter Routing for LTE course will provide you with the skills needed for the management and monitoring of the DIAMETER protocol in its use of the most advanced in mobile networks 3G and LTE and IMS architecture. In this course, the communication interfaces are analyzed, the signalling architecture and the main procedures for the control of the Charging functions, Policy Management and Authentication.
