Method for message marking and detection of message looping among signaling networks in a telecommunications system
First Claim
1. In a telecommunications system supporting a plurality of telecommunications service providers, each telecommunications service provider maintaining a separate signaling network interconnected by signaling links, a method for efficiently using signaling link resources interconnecting the signaling networks comprises the steps of:
- determining a signaling message must be extended to another signaling network;
including signature data identifying all telecommunications service providers that handled the signaling message, wherein the signature data is not a point code;
a first signaling network extending the message to another signaling network; and
the first signaling network subsequently discarding the signaling message upon recognition of the signature data.

Abstract
A method for prohibiting the continual routing of signaling messages among independent signaling networks requires including signature data in a called party identification field of each signaling message. Subsequent receipt of a signaling message in which the signature data in the called party identification field is recognized as being indigenous to the signaling network results in discarding the signaling message.

5. A local number portability-global title translation (LNP-GTT) system comprises:
-
processor means for creating signaling messages including signature data identifying a service provider that originated the message, wherein the signature data is not a point code; and storage means for storing the signature data for inclusion in signaling messages formulated by the processor means. - View Dependent Claims (6, 7)

8. In a telecommunications system including a signaling network for processing signaling messages, a method of accounting for signaling network resources used during processing of a signaling message comprises the steps of:
-
receiving the signaling message in a node of the signaling network; recognizing signature data identifying a service provider that originated the message, the signature data being stored in the signaling message, wherein the signature data is not a point code; and incrementing a counter within the message responsive to recognizing the signature data stored in the message. - View Dependent Claims (9)

10. In a telecommunications system supporting a plurality of telecommunications service providers, each telecommunications service provider maintaining a separate signaling network interconnected by signaling links, a method for eliminating continual looping of signaling messages among the signaling networks comprises the steps of:
-
a first signaling network determining a signaling message must be extended to a second signaling network; the first signaling network inserting a counter within the signaling message wherein the counter is not based upon a point code; receiving the signaling message in a node of the second signaling network; and the node in the second signaling network altering the counter included in the signaling message prior to extending the signaling message to another node. - View Dependent Claims (11, 12, 13)
