Abstract:
1. A method of delivering a notification to a wireless device via a wireless communications network where the wireless device provider has first and second wireless technology types, the method comprising the steps of: receiving a notification from a notification delivery sub-system for the wireless device; attempting to communicate the notification to the wireless device via [the first technology type; receiving, where the wireless device operates in the second technology type, an error signal that the attempting a first communication step has failed; receiving an error signal from a serving Mobile Switching Center (MSC) indicating that the wireless device is not reachable; delivering of a delivery notification to the location registry; logging by the location registry of the delivery notification for the not reachable wireless device; receiving by the location registry of updated location information from the serving MSC that the wireless device is now reachable; alerting by the location registry to the notification processor that the wireless device is now reachable; requesting by the notification processor from the location registry of routing for the wireless device; receiving of the routing from the location registry by the notification processor; forwarding of the delivery notification by the notification processor to the serving MSC for the wireless device; forwarding of the short message notification by the serving MSC to the wireless device; attempting to communicate the notification to the wireless device via the second technology type, wherein said attempting a second communication step includes the steps of: requesting routing for the wireless device from a location registry of the second technology type, wherein one of the first technology type or the second technology type is Time Division Multiple Access (TDMA) and the other technology type is Global System for Mobile Communication (GSM); receiving from the location registry of the second type routing for the wireless device; and subsequently sending of a message waiting notification to the wireless device through the serving MSC; receiving, where the wireless device operates in the second technology type and receives the notification, a delivery signal that the attempting a second communication step was successful; logging of the second technology type of the wireless device, after the delivery signal is received, as a default technology protocol to be used in the future; and thereafter, for the wireless device, attempting communication of future notification using the logged second technology type.
