Abstract
A method includes steps of (a) establishing a call connection between a terrestrial telecommunications network and a user terminal via a first gateway and at least one satellite, (b) while the call connection is established, selecting at least one further satellite, and (c) maintaining the call connection to the terrestrial telecommunications network via a second gateway, the least one further satellite, and the first gateway. The at least one further satellite is selected, at least in part, based on information transmitted from the second gateway to the first gateway through an inter-gateway communications link, and can be based on signal quality indications determined at the user terminal, signal quality indications determined at the gateway(s), or path gains calculated at the gateway(s).
