EMERGENCY SATELLITE NETWORK

摘要

An emergency satellite communications system that provides; remote sites with assured access. The network is provisioned, configured, and managed such that The remote units are always online., but not used to an extent that would prevent remote units from communicating via the network upon demand. The network, may include geographic hub diversity to protect against hub failure. Proactive monitoring of the components comprising the network is used, to mitigate or prevent network congestion, such as by bad balancing. An overflow link may be provided- allowing for remote sites (to be assigned from a first link to the overflow link to mitigate or prevent congestion on the first link, and/or allow for additional bandwidth to be allocated to one or more remote sites that remain on the first link. A satellite communication network may comprise a satellite and a network Management system operative in controlling and managing a plurality of first and second terminals, A first earth station may be communicatively coupled to one or more terrestrial communications networks, where the first earth station provides a first communication link via the satellite for bi-directional communication between the first -earth station and the plurality of first terminals assigned to the first earth station by the network management system, A second earth station may be geographically diverse from the first earth station and is communicatively coupled to at least one terrestrial communications network. The second earth station may provide a 'second communication link via the satellite for bi-directional communication between the second earth station and the plurality of second terminals assigned to the second earth station by the network management system.
