Document Type and Number:
Japanese Patent JP3587159
Kind Code:
B2
Abstract:
In a satellite communication system, an address adding portion 22 adds communication data with Next Hop address read out from a routing table portion 21 . A line controller 31 judges whether a satellite communication line to the Next Hop address of the IP packet is set or not. If no satellite communication line is set, a call-originating request message is transmitted to a DAMA call-originating table portion 32 . The DAMA call-originating table portion 32 has static DAMA call-originating information, and transmits to a DAMA call-originating portion 33 a DAMA call-originating request to the destination IP address of the call-originating request message. The DAMA call-originating portion 33 sets the satellite communication line to the Next Hop address by the DAMA call-originating request, and informs the line controller 31 of the setting of the satellite communication line.
