Apparatus and method for the detection and elimination of circular routed SS7 global title translated messages in a telecommunications network

A method for detecting and eliminating circular routed messages in a telecommunications network, comprising the steps of:

• receiving an SCCP message, the SCCP message including destination information and an originating point code identifying a source network element from which the message was received;
• performing a non-final global title translation and determining a derived destination point code for the received SCCP message in response to the destination information, the derived destination point code identifying a destination network element to which the message is to be transferred;
• comparing the derived destination point code with an originating point code in the SCCP message;
• identifying the SCCP message as a circular routed message in response to the derived destination point code being the same as the originating point code;
• and
• performing a predetermined error processing procedure on the circular routed message.

• determining a derived destination point code for the message in response to the destination information, the derived destination point code identifying a destination network element to which the message is to be transferred;
• obtaining a first routing information for routing the message to the destination network element indicated by the derived destination point code;
• obtaining a second routing information for routing to the source network element indicated by the originating point code;
• comparing the first and second routing information;
• and
• identifying the message as a circular routed message in response to the first and second routing information being the same.
