Introduction:
 

Traditional time and distance charging has been under attack in both fixed and mobile networks for some years and new, more sophisticated charging systems are being developed.

  • For UMTS, a new charging architecture was specified by the 3GPP standards group.
  • This evolved rapidly through Releases 6 and 7 of the 3GPP specifications and has been updated for LTE in Release 8.
  • Following the industry maxim of not offering a service until it can be charged for, charging eeds to be ahead of services in sophistication and this system is designed to cope with any future demands.
  • This has involved considerable change to the UMTS model.

This two day course presents the overall architecture of 3GPP Charging Management before specifically examining major aspects in some detail.

These include the interfaces between components and the associated Reference Points as well as specific charging areas such as IMS and Location Services (LCS). The Diameter Base Protocol provides the Authentication, Authorisation and Accounting (AAA) facilities needed by the architecture. Diameter thus replaces older systems such as RADIUS.
 
Audience:
 
  • Delegates needing an in-depth understanding of the 3GPP charging architecture and Diameter application especially as it has changed from the UMTS version
  • Delegates would be employed or contracted to:
  • --Operators
  • --Manufacturers
  • --Integrators
  • --Regulators
 
Prerequisites:
 
This course assumes an understanding of LTE core network architecture.
 
Customize it:
 
This 3-4-day LTE Charging Management and Applications course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of Wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization?s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit you into our standard, one size fits all, class. Please call or e-mail to schedule a no-obligation conference call to help us understand your audience background and training objectives.
