  • Method and apparatus for increasing call-handling capacity using a multi-tier satellite network
    Patent number: 6208625
    Abstract: A system for increasing call-handling capacity employs a multi-tier satellite network which includes one or more geosynchronous (GEO) satellites (12) and non-geosynchronous satellites (14). The GEO satellites (12) transfer non delay-sensitive data through the system, while the non-geosynchronous satellites (14) predominantly transfer delay-sensitive data through the system. In a preferred embodiment, a non-geosynchronous satellite (14) receives (102) a data packet, determines (112) whether or not the data packet is delay-sensitive, routes (114) a delay-sensitive data packet through the LEO network, and routes (116) a non delay-sensitive data packet to a GEO satellite (12).

  • Method and apparatus for linking terminals using private secondary service paths (PSSP) in a satellite communication system
    Patent number: 6157624
    Abstract: Private Secondary Service Paths (PSSPs) between compatible or non-compatible communication terminals (110, 120) are established using terrestrial stations (130) within a satellite communication system (100). Each PSSP provides to its users the ability to establish communication paths between compatible or non-compatible terminals. A PSSP is established using terrestrial stations (130) which establish and maintain terrestrial-based links (115, 125) and satellite communication links (135). Terrestrial stations also perform frequency translating and data reformatting to allow non-compatible terminals to communicate with each other. All data can be sent between terminals over satellites (140), or user data can be sent via terrestrial connections (150) while overhead data is sent via satellites (140).

  • Method and apparatus for providing private global networks in a satellite communication system
    Patent number: 5999797
    Abstract: Private Global Networks (PGNs) between communication terminals (110, 114, 116, 118) are established within a satellite communication system (100). Each PGN provides to its users a network of dedicated communication paths which have durations that exceed the duration of a particular call. A dedicated communication path is established by determining (416, 424) hand-off schedules for satellite-to-terminal links for both a source and destination terminal, and also by determining (428) satellite cross-link schedules necessary to maintain the dedicated path for a duration which exceeds the duration of a particular call.
