PURPOSE:To simplify the procedure and to improve the quality of call data transfer for a marine satellite communication system by transferring the call data within said communication system via a two sea area service coast earth station. CONSTITUTION:A two sea area marine service coast station 8 is designated by a pseudo marine equipment 24 when the call data including the record on a coast station 9 is transmitted to a call data collecting station 7. At the same time, the data calls are sorted and the ship number of the station 7 is dialed. The station 8 receives the ship number under the control of a network coordination station 11 and calls the station 7 under the control of a network coordination station 10 after returning a data call with an access/control device 18. When the connection is over, an access/control device 23 of the station 9 transfers the call data to the station 7 through a set route. |
