As I recall, no mandatory calls are made by pilots or ATC during LVPs except by ATC to state that LVPs are in progress, which probably goes out on the ATIS. At airports where there is no ground radar pilots may be asked to report when they are clear of the runway. In the approach phase ATC may ask aircraft for their minima but this is purely for information.
The protected range of the ILS is promulgated in the AIP.
