Filed:

Jun 3, 2002

Appl. No.:

10/161532

International Classification:

H04J003/24

US Classification:

370/474000

Abstract:

An IP sub-network includes a gateway and a plurality of sub-network processors in communication with the gateway. An IP address is associated with each sub-network processor, the IP address having a sub-network address portion corresponding to the sub-network and a host address portion corresponding to the sub-network processor. Each sub-network processor generates a transaction identifier for each signaling message that is communicated by the gateway to the signaling network. The transaction identifier is based on the IP address and can be generated by separating the sub-network address portion of the IP address and concatenating the host address portion with a numerical value, which corresponds to a predetermined, non-random ordering scheme. A signaling message can be routed to a sub-network processor by concatenating the sub-network address portion with the host address portion used as part of the transaction identifier.

Abstract:

Systems and methods for identifying a bad actor component needing repair or replacement are provided. The systems and methods can track unscheduled shopping events for maintenance or repair of equipment and identify a segment of the unscheduled shopping events. The segment represents a period of time during which the unscheduled shopping events occurred at a rate or frequency. A usage metric of parts in connection with the unscheduled shopping events occurring during the segment is determined. The usage metric indicates a cumulative amount of usage of the parts in connection with the unscheduled shopping events during the segment for the equipment relative to the cumulative amount of usage of the parts in connection with the unscheduled shopping events for other equipment during one or more other segments of equal length. The bad actor component in the equipment is identified based on the usage metric that is determined.
