摘要：
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.
摘要（中）：
提供了一种方法和一种卫星通信系统。 至少有一个卫星网关地球站从外部网络接收至少一个组播流。 在静态转发模式中，所述至少一个卫星网关地球站通过卫星的至少一个第一相应点波束的至少一个第一相应外围载波复制并转发来自所述至少一个多播流的业务，而不管任何终端是 被安排为主动接收至少一个多播流中的任何一个。 在动态转发模式中，至少一个卫星网关地球站仅在至少一个相应点波束的至少一个第二相应外围载波上通过至少一个第二相应点波束的至少一个第二相应外围载波复制并转发来自至少一个多播流中的任何一个的第二业务 终端被安排为主动接收至少一个多播流中的任何一个。
