发明名称 Transfer of a communication in a non-geostationary satellite constellation
摘要 <p>The method involves determining the distance (D(i)ÄjÜ) between the user and the point of satellite handover in each cell (CÄjÜ). If the distance is greater than a predetermined distance (DmaxÄjÜ) equal to the maximum length of the cell parallel to the satellite direction, a communication channel reservation is requested in the cell at the predetermined distance. If the distance is lesser than the predetermined distance, the communication link is refused (E6) if no channels are free, otherwise a channel is reserved (E7). A channel is refused if the number of users in a region in the satellite direction between the first distance and a second distance at least equals (E9) the capacity of the cell. This second distance, D(i)Äj+1Ü, is that between the user and the point of transfer in the next allocated cell, CÄj+1Ü .</p>
