Looks more like a national licencing issue - the issue of licences to operate in a given band. The allocation of frequency bands is done internationally.
It is true that the aeronautical bands have been under threat in the last few meetings of the ITC, as mobile phone operators pile on the pressure to take over some of the choice bands currently used for navigation. We do need to defend our patch at the ITC, but this Ofcom initiative doesn't seem to be part of the attack.
