Method for providing call charge information in a telecommunication link

摘要

The invention relates to a method for providing call charge information in a telecommunication link between a calling subscriber with a first terminal and a called subscriber with a second terminal. The first terminal is connected to a first local telecommunication exchange and the second terminal is connected to a second local telecommunication exchange. Call charges arising for the telecommunication link are determined in the first telecommunication exchange and corresponding call charge information is sent as messages to the second telecommunication exchange to enable the call charge information to be used there in real time while the telecommunication link is in existence.
