NOTE – Use case 3: Composite use case comprised of partitioning
and aggregation of wireless networks

Figure II.4 – Composite use case of wireless access network virtualization

Figure II.4 shows a composite use case comprised of use cases 1 and 2 in Figure II.3.
Explanation: Each MVNO can lease a reasonable amount of wireless network resources from MNOs
according to their own service requirements so that it can be realized by partitioning in network
virtualization (Step 1 in Figure II.4). After that, a set of LINPs which is leased by the same MVNO can
be aggregated (Step 2 in Figure II.4) into a single virtualized wireless network and thus the set of
LINPs appears to the users as a single wireless network. This use case also has the same benefits as
described above.
– When?

• Mobile network operator (MNO) requires these services now
II.4.2 Current status of technology

– There is a technology called wireless virtualization which describes how the radio resource sharing
can be performed efficiently without interference between the different virtual wireless networks
