Abstract: PURPOSE: A frame structure for unicasting and multicasting transmission and frame efficiency of a satellite time division multiple access and a method for controlling the same are provided to increase frame transport efficiency of traffic bursts and reduce unnecessary data processing load of a ground network connecting part of traffic earth stations. CONSTITUTION: Each traffic earth station reads frame data and extracts receiving earth station address signals from the read frame data, so that each traffic earth station inspects the highest level bit to judge unicasting. In the case of the unicasting, the traffic earth stations read the rest of bits to judge whether the bits are addresses of local earth stations. If not, the traffic earth stations read the rest of bits to judge whether the bits are broadcasting. In the case of the broadcasting, the earth stations receive the corresponding data. If not, the earth stations decides to receive data according to groups of the data.
