Abstract
The invention relates to a method for charging for telecommunications links in a communications network. When a setup request for a communications link which is directed to a communications terminal and incurs a charge for a charge account associated with the communications terminal is deleted, a network node in the communications network performs sequences for setting up the communications link and forwarding sequences for setting up a forwarding communications link. To bill telecommunication charges securely and reliably at all times, even in the course of roaming, forwarding information is stored in a memory network node in the communications network during the forwarding sequences. Debiting of communication charges for the communications link from the charge account associated with the communications terminal is prevented if the memory network node stores the forwarding information.
