Abstract:
Transferring context data from a first network functional set, NFS, to another. A method and apparatuses provide for transferring restoration context data from a first NFS toward a second NFS. This method includes receiving, at the first NFS from a context transfer requester, a transfer request indicating transfer of context data toward the second NFS; transmitting, from the first NFS toward a network repository function, NRF, a context transfer request indicating transfer of context data from the first NFS to the second NFS; transmitting, from the NRF toward the first NFS, a context transfer response indicating a status of the first NFS; notifying, from the NRF toward a network function, NF, service consumer, of transfer information related to the transfer of context data from the first NFS to the second NFS; transferring, from the first NFS toward the second NFS, restoration context data; and storing the restoration context data.
