Patent ID: 7466815

Claim:
A method for detecting signaling connection control part (SCCP) looping in a telecommunications network, the method comprising: (a) receiving, at a signaling message routing node, an SCCP message from an originating node; (b) performing global title translation (GTT) for the SCCP message and thereby determining a destination point code (DPC) for the signaling message; (c) comparing the post-GTT DPC with a first point code stored in a message transfer part (MTP) originating point code (OPC) associated with the SCCP message; (d) in response to detecting a match in step (c), identifying the presence of SCCP looping for the SCCP message; (e) in response to failing to detect a match in step (c), mapping the first point code to at least one second point code of a plurality of point codes used to identify the originating node; (f) comparing the post-GTT DPC to the at least one second point code; and (g) in response to detecting a match in step (f), identifying the presence of SCCP looping for the signaling message.
