Abstract:
1. A method for selectively processing or redirecting signaling connection control part (SCCP) messages, the method comprising: receiving, at a signal transfer point, an SCCP message that is both addressed to the signal transfer point and sent route-on-point-code-subsystem-number (route-on-PC-SSN), wherein the SCCP message includes a request for the location of a called party; determining whether the SCCP message can be processed locally by the STP; in response to determining that the SCCP message can be processed locally by the STP, processing the SCCP message locally at the STP and sending a response to an originator of the SCCP message, wherein the response indicates that the called party is a Global System for Mobile Communications (GSM) subscriber, wherein processing the SCCP message locally at the STP includes terminating the message at the STP rather than routing the message; and in response to determining that the SCCP message cannot be processed locally at the STP, redirecting the SCCP message from the STP to a destination by altering a message transfer part (MTP) point code in the SCCP message.
