The traditional telecommunications billing paradigm of time and distance 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 needs to be ahead of services in sophistication and this system is designed to cope with any future demands.
This 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, Authorization and Accounting (AAA) facilities needed by the architecture. Diameter thus replaces older systems such as RADIUS.
Policy-based charging is also covered.
