1. A method performed by a network node for encoding public land mobile network (PLMN) information, the method comprising:
determining a core network type associated with each cell of a plurality of cells;
identifying at least one cell that is associated with more than one core network type;
transmitting a message comprising PLMN information associated with the at least one cell that is associated with more than one core network type, the PLMN information comprising identification information for at least one PLMN associated with an evolved packet core (EPC) core network type wherein the message explicitly includes the identification information for the at least one PLMN associated with the EPC core network type and does not explicitly include identification information for at least one PLMN associated with a 5G Core core network type.
