Patent ID: 6990332

Claim:
In a method for transmitting subscriber-specific information in a telecommunication system that includes a telecommunication network, a conversion/transmission center connected to the telecommunication network, a first telecommunication terminal having an associated A-number and connected to the conversion/transmission center through the telecommunication network, a second telecommunication terminal having an associated B-number and connected to the conversion/transmission center through the telecommunication network, and an actuating device connected to the second telecommunication terminal, wherein connection-specific information is transmitted from the first telecommunication terminal to the second telecommunication terminal to effect a call from the first telecommunication terminal, and subscriber-specific optional parameters are added to a dialing string sent to the conversion/transmission center from the first telecommunication terminal to initiate the call such that the dialing string includes at least the B-number and the subscriber-specific optional parameters, the improvement comprising the steps of: sending a dialing string including the B-number and subscriber-specific optional parameters from the first telecommunication terminal to the conversion/transmission center to initiate the call; determining, at the conversion/transmission center, the B-number and the subscriber-specific optional parameters from the dialing string received from the first telecommunication terminal; modifying an A-number field to be transmitted from the conversion/transmission center in the telecommunication network to the second telecommunication terminal in connection with the call by one of adding control information to the A-number field and replacing the A-number field with the control information, the control information comprising at least a portion of the subscriber-specific optional parameters in the dialing string sent to the conversion/transmission center from the first telecommunication terminal to initiate the call; and controlling the actuating device in accordance with the control information contained in the modified A-number field.
