Abstract
A multicast message is transmitted from an originating subscriber unit (,, FIG.,) through a network of satellite communications nodes (,, and,) to a plurality of receiving subscriber units (,, and,). Each message is distributed through the network of satellite communications nodes (,, and,) and replicated at the node nearest to the receiving subscriber unit. Receiving subscriber units (,, and,) are mapped into geographic cells which allows a single multicast transmission to be transmitted from the satellite communications node to those subscriber units within the same geographic cell. Multicast groups and membership rules are established by the originating subscriber unit (,) through a service provider (,). A multicast session manager (,) manages the multicast session.
