1. A method for determining an unreported event status change for an asset within a computer-based asset management system, the asset management system including a data receiver, a database, a processor, and an alert trigger service, the method comprising:

  • receiving at the data receiver a first event status of the asset from a wireless reporting source coupled with the asset, the first event status being a most recently received reported event status and indicating that the asset is stationary;

    storing the first event status as a maintained event status of the asset in the database;

    receiving at the data receiver a first position of the asset from the wireless reporting source at a first time;

    receiving at the data receiver a second position of the asset from the wireless reporting source at a second time while the reporting source is in a power conservation operating mode, the second time being later than the first time;

    determining at the processor a second event status of the asset indicating that the asset is moving based on a distance between the second position and the first position and a time difference between the second time and the first time;

    determining at the processor that the second event status is different from the first event status by comparing the second event status and the first event status;

    in response to determining that the second event status is different from the first event status, determining at the processor that the difference is due to a failure to receive an updated event status of the asset from the wireless reporting source; and

    issuing through the alert trigger service a status alert regarding the asset in response to determining that second event status satisfies a pre-defined alert reporting criterion.
