Abstract
A method for managing resource usage within a cellular communications system (10) having at least one satellite (12) and, capable of communicating with the satellite(s) (12), at least one controlling station (28) and multiple ground terminals (26). The controlling station (28) predicts (372, 380) system communication traffic and operating capabilities for a future period; generates (216) a system plan (250) and an individual operational plan (270-30n) for each satellite (12) based on the prediction; distributes (222) each individual operational plan (270-30n) to each corresponding satellite (12); monitors (226) execution of the system plan (250) during the future period to determine (228) whether the plan is operating acceptably and when the plan is not operating acceptably (228), generates (216) a new plan, or portion thereof, to alleviate the unacceptable operation; and repeats the foregoing steps for additional future periods. Each satellite (12) receives (502), stores (504), executes (224) and monitors execution (226) of its individual operational plan (270-30n) and transmits out-of-plan messages (338) to the controlling station (28) when it detects an out-of-plan condition (336).
