A radio communication route enables communication from an originating ground station to a destination ground station via one of multiple randomly orbiting, rotating satellites with no active attitude control. The ground stations and satellites include directional antennas for receiving radio signals from and transmitting radio signals in multiple directions. The satellites store an address of a destination ground station from which an initial information signal is transmitted and antenna information identifying the satellite antenna on which the initial information signal was received. Plural satellite antennas transmit linking information identifying the satellite to the originating ground station. Data transmissions received at the originating ground station that designate a particular destination are transmitted by the originating ground station using the antenna on which the linking information was received and the satellite retransmits the data transmission using the satellite antenna identified by the stored antenna information.

A method and system for providing GTP acceleration for secure cellular backhaul over satellite (CBoS). A satellite terminal receives request from a first entity to establish a security association with a second entity, and establishes a first secure tunnel to a gateway. A second secure tunnel is then established between the gateway and the second entity based on a certificate belonging to the first entity. A third secure tunnel is established between the satellite terminal and the first entity based on a certificate belonging to the second entity. The contents of encrypted traffic between the first entity and the second entity are examined so that GTP acceleration may be applied to eligible traffic transmitted over the first secure tunnel.
