Abstract
A method for providing for network function (NF) fallback to a recovered network function NF repository function (NRF) includes, at an NF including at least one processor, generating an NF register message including an indication to notify the NF of recovery of a first NRF after a failure of the first NRF. The method further includes transmitting the NF register message to the first NRF. The method further includes communicating with the first NRF and detecting failure of the first NRF. The method further includes, in response to detecting failure of the first NRF, initiating communications with a second NRF that is a geo-redundant mate of the first NRF. The method further includes receiving notification of recovery of the first NRF and falling back to communicating with the first NRF.
