How come more than two gateways in handling a call? I suppose that is because a handset on a receiving and sending link will send the call via a variety of gateways and satellites as the constellation zooms around. When the person first hits 'send', the call will go to the nearest satellite, which might link with a gateway off to the east of the caller. Then, as that satellite disappears, the next satellite visible might be off to the west [most likely as they are going west to east]. But the new satellite might be connecting via a difference gateway further still off to the west. The same process might happen on the receiving end. With 3 gateways in Australia, I can imagine a situation where all three would handle a call at some stage. If a call lasts 30 minutes, that could involve 4 satellites. So a single half hour call from Australia to USA could involve 6 gateways, 8 satellites and some fibre. Maybe in some situations, a gateway might hand a call up to another satellite then down again to a different gateway to avoid some awkward or expensive or disrupted terrestrial link. Say somebody cut both Dubbo fibres. The gateway could presumably still function by handing calls up to another satellite and down to the Mount Isa gateway. Gateways with a handset 'in view' would also retain the handset on each of their Visitor Location Registers because any time, the signal to one gateway might be cut off by a building or other obstruction so an instant maintenance of the call would be needed by a fast soft handoff to another satellite which might be connected via another gateway.
