Multicast service delivery over high throughput satellite in a Ka spot-beam network
First Claim
1. A satellite communication system comprising:
- one or more satellite gateway earth stations; and
a satellite configured to communicate with a plurality of terminals via a plurality of spot beams formed by the satellite, each of the plurality of terminals being arranged to receive communications via the satellite and a respective spot beam of the plurality of spot beams, wherein;
the one or more satellite gateway earth stations is arranged to receive one or more multicast streams from an external network, andwhen a satellite gateway earth station of the one or more satellite gateway earth stations is configured to be in a static forwarding mode, the satellite gateway earth station is statically configured to replicate and forward each of the one or more multicast streams over one or more first respective outroute carriers of at least one first respective spot beam of the plurality of spot beams regardless of whether any terminals are arranged to actively receive any of the one or more multicast streams, andwhen the satellite gateway earth station is configured to be in a dynamic forwarding mode, the satellite gateway earth station is dynamically configured to replicate and forward ones of the one or more multicast streams over one or more second respective outroute carriers of at least one second respective spot beam of the plurality of spot beams only when at least one respective terminal is arranged to actively receive each of the ones of the one or more multicast streams over the one or more second respective outroute carriers of the at least one second respective spot beam of the plurality of spot beams.

Abstract
A method and a satellite communication system are provided. At least one satellite gateway earth station receives at least one multicast stream from an external network. In a static forwarding mode, the at least one satellite gateway earth station replicates and forwards traffic from the at least one multicast stream over at least one first respective outroute carrier of at least one first respective spot beam of a satellite regardless of whether any terminal is arranged to actively receive any of the at least one multicast stream. In a dynamic forwarding mode, the at least one satellite gateway earth station replicates and forwards second traffic from any of the at least one multicast stream over at least one second respective outroute carrier of at least one second respective spot beam only when at least one respective terminal is arranged to actively receive the any of the at least one multicast stream.

14. A method for providing support for multicast sessions in a satellite communication system, the method comprising:
-
receiving, by a satellite gateway earth station, a multicast stream from an external network; replicating and forwarding, by the satellite gateway earth station, the multicast stream over at least one respective outroute carrier of at least one respective spot beam of a plurality of spot beams of a satellite regardless of whether one or more terminals are arranged to actively receive the multicast stream over the at least one respective outroute carrier, when the satellite gateway earth station is configured to be in a static forwarding mode; and replicating and forwarding, by the satellite gateway earth station, the multicast stream over at least one respective outroute carrier of at least one respective spot beam of a plurality of spot beams of a satellite only when a respective terminal is arranged to actively receive the multicast stream over each of the at least one respective outroute carrier of each of the at least one respective spot beam, when the satellite gateway earth station is configured to be in a dynamic forwarding mode. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
