Patent ID: 7006528

Claim:
A method for establishing a signaling connection with a terminal ( 102 , 103 , 104 ) in a central unit ( 101 ) of a communications system, said terminal and central unit comprising a network interface ( 107 , 108 , 109 ) and signaling unit ( 105 , 106 , 110 ) characterized in that it comprises steps in which by communication between the central unit's network interface ( 107 , 108 ) and the terminal's network interface ( 109 ), information is created about the signaling protocol supported by the terminal, and signaling is started using a signaling unit ( 105 , 106 ) in the central unit that supports the same signaling protocol as the terminal, wherein: a message ( 201 ) is sent from the central unit's network interface ( 107 ) to the terminal, indicating the signaling protocols supported by the central unit, in response to an answer message ( 202 ) sent by the terminal indicating the terminal's selection for signaling protocol, a connection is established ( 203 , 204 ) between the central unit's network interface ( 107 ) and the central unit's signaling unit ( 105 ) that supports the signaling protocol chosen by the terminal, and a point-to-point signaling connection ( 205 ) is established between the central unit and the terminal using the signaling protocol selected by the terminal.
