1. A method, comprising:
determining, by a user equipment comprising a processor, a predicted departure of the user equipment from a geographic area served via a private cellular network;
generating, by the user equipment, an encryption key that is local to the user equipment, in response to the determining the predicted departure;
encrypting, by the user equipment, a user equipment parameter using the encryption key that is local to the user equipment, resulting in an encrypted user equipment parameter;
sending, by the user equipment, the encrypted user equipment parameter to a private cellular network server that is part of the private cellular network, wherein the encrypted user equipment parameter is sent to the private cellular network without the encryption key;
deleting, by the user equipment, the user equipment parameter from the user equipment;
receiving, by the user equipment, a code generated by the private cellular network server;
storing, by the user equipment, the code for subsequent use by the user equipment in connection with re-acquiring the encrypted user equipment parameter from the private cellular network server; and
providing, by the user equipment, the code to the private cellular network server in order to re-acquire the encrypted user equipment parameter.
