Advanced subscriber outage notification methods (100) notify a user of a subscriber unit (30) that its call is going to be dropped. The subscriber unit (30), the satellite (20) or the mobile telecommunication system (10) first predicts whether an outage is going to occur and how much time there is before the outage. Second, the subscriber unit (30) notifies the user of the outage and the time remaining before the outage. Third, the subscriber unit (30) waits for whether the user wants to end the call. Next, the subscriber unit (30), the satellite (20) or the mobile telecommunication system (10) terminates the call if the user wants to end the call. Lastly, the mobile telecommunication system (10) drops the call once the time remaining before the outage expires.
