Verfahren zur Übernahme von Anrufsgebühren in einzelnen Verbindungen sowie Telefonnetz und Endgerät

摘要

After the sharing of charges between both subscribers has been negotiated, the calling subscriber (A) transmits a caller-specific signal as a confirmation of this agreement, and subsequently the called subscriber accepts the call. The caller-specific signal may be a digital code which is stored in the calling subscriber's terminal. A telephone network, a chip card and a terminal are also claimed.
