A simplified evaluation of messages that control connection setup is made possible by a method for filtering ( 4 ) incoming messages ( 3 ) at a connection controlling element ( 5 ) of a telecommunications network ( 13, 14, 5 ) on the basis of predetermined filtering conditions ( 8 ). According to this method, the filtering ( 4 ) ensues by comparing ( 4 ) text elements ( 20 to 29 ) in a received ( 6 ) message ( 3 ) with text elements ( 20 to 29 ) in a document ( 8 ), which can be accessed ( 7 ) by the connection controlling element ( 5 ) and which contains the filtering conditions in the form of text elements ( 20 to 29 ), and by verifying ( 4 ) whether, inside the document ( 8 ), logical links ( 30 to 32 ) of filtering conditions ( 20 to 29 ) apply to the message ( 3 ), said logical links being specified in an internet page description method (XML). |
