1. A network repository function, NRF, node configured to assist in transferring restoration context data from a first network functional set, NFS, node toward a second NFS node by being configured to:
receive, from the first NFS node via a receiver, a context transfer request indicating transfer of context data from the first NFS node to the second NFS node;
transmit, toward the first NFS node via a transmitter, a context transfer response, the context transfer response indicating a status of the first NFS node and indicating that the transfer of context data from the first NFS node is ongoing; and
notify, a network function, NF, service consumer node via the transmitter, of transfer information related to the transfer of context data from the first NFS node to the second NFS node.
