16.14.14 NG Removal
For the case of regenerative payload, when disconnecting from an AMF is required due to e.g. the satellite movement in a LEO constellation, the gNB on board the satellite may request the removal of the NG interface by initiating the NG Removal procedure toward the AMF based on e.g. ephemeris information.
NOTE: After a successful NG removal, the gNB may initiate a new NG Setup procedure, if required, based on e.g. ephemeris information.
