Claim 8:
9. A system comprising a Unified Data Repository, UDF, network function, NF, and a network node hosting a Network Function, NF, service consumer for being notified from a Unified Data Repository, UDR, of a policy data modification, the network node hosting the NF service consumer comprising processing circuitry configured to:
transmit, to the UDR, a subscription request, from the NF service consumer hosted on the network node, a notification notifying the NF service consumer hosted on the network node of the policy data modification for
a Public Land Mobile Network, PLMN, user equipment, UE, Policy Set to allow the UDR to determine the policy data modification;

receive, from the UDR, the notification for the NF service consumer hosted on the network node that has subscribed to the notification of the policy data modification, the notification notifying the NF service consumer of the policy data modification for
the PLMN UE Policy Set, along with a PLMN identifier; and

the UDR comprising processing circuitry configured to:
receive, from the NF service consumer hosted on the network node, the subscription request to the notification notifying the NF service consumer hosted on the network node of the policy data modification;
determine the policy data modification, the policy data modification being for the PLMN UE Policy Set; and
transmit, to the NF service consumer hosted on the network node that has subscribed to the notification of the policy data modification, the notification notifying the NF service consumer of the policy data modification for the PLMN UE Policy Set, along with the PLMN identifier.
