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.

Abstract: A method for transmitting short messages from a mobile terminal and a method for receiving short messages from a mobile terminal, in each case in a mobile radio network, wherein the short message service center is a central point in the network for short messages and the approach to a solution which is acceptable for the network operator is a closed concept with respect to SMS, starting from the original terminal, or ending at the terminating terminal.

Abstract: A method and system for sending out short messages from a mobile terminal in a mobile radio network, wherein the incoming/outgoing CAMEL application part interaction is suppressed at the mobile switching center, but the short message is processed in an IN-related manner at the short message service center. In the mobile originating (transmitting) case, the mobile switching center takes from the short message service the calling party address, and in the mobile terminating (receiving) case it takes the called party address and sends it, together with a transmitting/receiving indication, to the home location register of the terminal via an unstructured supplementary service data string.
