摘要： A method for controlling data transmission rate in order to save waste of resources due to Non-Line Of Sight (NLOS) region when a mobile terminal passes through the NLOS region in an interactive satellite communication system is disclosed. The method includes the steps of setting at least one threshold; at a Network Control Center (NCC) adjusting allocated resources based on the Constant Resources Allocation (CRA) after detecting whether Satellite Access Control is lost or not; compensating transmission delay by reallocating if the mobile terminal returns from the NLOS region within a first threshold duration, wherein the mobile terminal maintains the fine sync state during the first threshold duration; and deallocating all resources allocated based on the CRA if the mobile terminal does not return from the NLOS region within the first threshold duration.
