1. A method of allocating resources in an interactive satellite communication system employing a problem decomposition technique, comprising the steps of:
a) accumulating an amount of resource requests being created during a super-frame period for each terminal;
b) deciding a resource allocation amount to be allocated to each class of each terminal, depending on a preset weight to minimize a difference from the accumulated resource request amount for each class of each terminal; and
c) selecting and mapping timeslots to be allocated to said each terminal based on the decided resource allocation amount,
wherein said class is defined as being either a clear-sky terminal where no radio wave obstacle exists or a rain-fade terminal where radio wave obstacles do exist.
