A Mobile LLU (Local Loop Unbundling) system would be slightly
different that an MVNO. MVNO's mostly differentiate themselves on
branding instead of services. LLU is what you get when you force
ILECs (Incumbent Local Exchange Carriers) to allow third parties to
connect to the local loop
at the carrier's data center and hook directly into their
terrestrial SS7 network. That way it would be accessible to the whole
network.
