To charge specific services in telecommunication area a specific, flexible solution was developed.
The available charging systems in 1998 were quite static and able to charge services only based on domains (time, day, range). A new system was developed. With the new system the charging model was described with a script language. With that exotics charging functions like reduced prices on the birthdays of the customer were possible. The solution was created from scratch based on the C++ programming language.
The solution was successfully established on the market and is still in the business.
