Abstract
If interaction between signaling gateways frequently occurs, it is possible that extended processings are executed redundantly on a path of signaling messages. To avoid such a redundancy, a consistent method is necessary for deciding a signaling gateway to execute an extended processing from among the signaling gateways. The signaling gateways, each time they receive a signaling message, calculate information about a path through which it is transferred. By passing the path information in addition to the signaling message to an extended processing program, the signaling gateways decide whether to execute the extended processing on the signaling gateways, on a session basis. A signaling gateway that has executed an extended processing adds information indicating a processing status to the signaling message to notify other signaling gateways of it.
