1. A method comprising:
assigning, to a first functional group associated with a user equipment (UE), a first priority to access a first cell of a private cellular network operating in a Citizens Broadband Radio Service (CBRS) spectrum, the first priority being different than at least one of a second priority of the first functional group to access a second cell of the private cellular network or a third priority of a second functional group to access the second cell;
mapping the first functional group to a cell identifier of the second cell and to the second priority to access the second cell;
mapping the second functional group to a cell identifier of the first cell and to a fourth priority to access the first cell, the fourth priority being different than the first priority;
receiving, at a network device of the private cellular network, an indication of a condition of the first cell of the private cellular network;
determining, for the first functional group, an access priority for the UE to access the first cell, the access priority being based on the first priority to access the first cell and the indication of the condition of the first cell; and
providing the access priority to a CBRS access point (AP) that controls access to the first cell, wherein the access priority indicates to the CBRS AP a cell-specific priority with which the UE is allowed to access the first cell.
