Abstract:
A method for preventing fraudulent use of resources in a satellite communication system, said satellite communication system comprising a plurality of satellites coupled together by a plurality of crosslinks and a plurality of gateways coupled to said plurality of satellites, wherein said plurality of gateways and said plurality of satellites comprise a plurality of switchable nodes, said method comprising the steps of:establishing a signaling traffic connection between an originating communication unit and a terminating communication unit using at least one of said plurality of satellites;using a switchable node for restricting access to said resources by prohibiting a mission traffic connection from being established between said originating communication unit and said terminating communication unit until said terminating communication unit sends an acceptance message;establishing a segment between said originating communication unit and a satellite of said plurality of satellites;establishing another segment between said satellite and said terminating communication unit;operating said satellite as said switchable node; andconnecting said segments as said mission traffic connection using said satellite when said satellite receivers said acceptance message.
