Patent ID: 6965598

Claim:
A signal traffic routing method for a signaling network, comprising: receiving a signal message at a signal transfer point, analyzing a routing label of the received message, and determining the final destination; analyzing whether the final destination of the received signal message is a local system based on a result of the analysis; transferring the received signal message to a message routing unit when the final destination is not the local system; setting a signal route for transferring the signal message using a Signaling Link Selection of the routing label; selecting a link for the signal message from the link set of the set route using link determination history and link determination data; and updating the link determination history data based on the selected link, wherein selecting the link comprises: checking the link determination history to determine whether the signal message is to be routed based on the same Signal Link Selection as a previous Signal Link Selection and routing the signal message through the corresponding link from the link determination history when the signal message has been previously routed using the same Signal Link Selection; and routing the signal message through a next available link excluding the link from the link determination history when the signal message has not been previously routed using the same Signal Link Selection.
