<p>PURPOSE:To surely and effectively manage routing information. CONSTITUTION:Call setting request data S2 is default-transmitted from an extremely small earth station 11-1 with a call terminal 12 to a center station 1. A routing information storage device 10 of the center station 1 retrieves routing information of a terminal 13 (32) to be called. When the retrieval is available, call setting request data S3 with the routing information added is sent from the center station 1 to an extremely small earth station 11-n with the terminal 13 to be called and the call is set. When the retrieval is not available, call setting request data S2 is default-transmitted to the other center station 2 with routing information storage device 20 capable of retrieving the routing information. The call setting request data with the routing information added is sent from the center station 2 to the micro earth station 31-n and the call is set.</p> |
