Claim Text:
1. A method for ensuring restoration of Mobile-Originated (MO) and Mobile-Terminated (MT) services to an end-user of a network operator upon failure of a Proxy Profile Gateway, the method comprising: determining a failure of the Proxy Profile Gateway, the failure rendering the Proxy Profile Gateway unavailable; tracking, by a Proxy Saver, an actual location of the end-user by monitoring roaming signaling links between the Proxy Profile Gateway and all network end nodes; removing, based on the tracking, the end-user from a list of end-users identified for restoration of MO and MT services when the restoration is no longer necessary based on a mobile-initiated procedure; initiating restoration of MT and MO services to the end-user based on refreshing the actual location of the end-user in a stored profile at the Proxy Profile Gateway; and monitoring the initiated restoration.
