Abstract
A method for efficiently and rapidly handing off a subscriber link from a first satellite ( ) to a second satellite ( ) in a satellite communications system ( ) uses a virtual connection ( ) between the first satellite ( ) and a subscriber ( ) through the second satellite ( ). The virtual connection ( ) is established soon after a handoff decision has been made. All signals subsequently received by the first satellite ( ) for direct transmission to the subscriber ( ) are then automatically transferred to the subscriber ( ) through the virtual connection ( ). The virtual connection ( ) is terminated after a “call rerouted” signal has been received from a remote gateway ( ).
