Thus spaketh Graham Gower:
Do switching centres lookup a person's phone in the local VLR before
> searching for its HLR?
> e.g., If my friend from Sydney calls me when I get off the plane
> (at Sydney airport), does the switching centre realise that I'm
> already connected to the local VLR, or will it try to find me
> via my HLR instead?
> Would this happen often enough for it to be a worthwhile optimisation?
