摘要： A communication system (100) includes an aircraft (120) that acts as a repeater between ground equipment (101) and communication units (128) on the ground. The ground equipment (101) includes multiple base transceiver stations (104, 106, 108) that provide traffic channels, control channels, and access channels. The channels are all in a single beam (124) projected from aircraft (120). Relative loading on access channels is influenced by access class lists (200, FIG. 2) assigned to control channels. Access classes can be transferred from one list to another, or they can be removed from a list. Relative loading of traffic channels on the base transceiver stations is influenced by assigning different time offsets to base transceiver station so that calls can be transferred from one base transceiver station to another.

摘要： A multicast message is transmitted from an originating subscriber unit (110, FIG. 1) through a network of satellite communications nodes (120, 130, and 140) to a plurality of receiving subscriber units (150, 160, and 170). Each message is distributed through the network of satellite communications nodes (120, 130, and 140) and replicated at the node nearest to the receiving subscriber unit. Receiving subscriber units (150, 160, and 170) 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 (110) through a service provider (180). A multicast session manager (185) manages the multicast session.
