<p>A method (300, Fig. 3) controls CU (140, Figs. 1, 6) hand-off in a non-geostationary orbit (NSGO) satellite system (100, Fig. 1) without consuming large amounts of bandwidth or satellite processing power. Using method (300), a network control facility (NCF) (130, Figs. 1, 5) divides the earth (102, Fig. 2) into suitable regions 200 (Fig. 2), or geographical areas of the earth sized so that all of the CUs (140, 142, 144, Fig. 1) within a region (200) can be handed-off as a group rather than handling each station individually. When it is determined through the method (300) that it is time to hand-off communications in a particular region, all CUs within that region are directed to effectuate a hand-off at substantially the same time.</p> |
