RESILIENCY AGAINST NRF FAILURE IN A 5G NETWORK

Abstract: the technology disclosed herein enables resiliency of routing between nfs when degraded 5g nf topology information is provided to an scp by an nrf. in a particular example, a method includes transmitting requests for nrf status from a service communications proxy (scp) to nrfs in a 5g network. the nrfs exchange messages with each other to determine whether network function (nf) topology information is available from the nrfs. the method further includes receiving responses to the requests in the scp. the responses indicate a number of the nrfs from which the nf topology information is available. the method also includes identifying one or more failed nrfs of the nrfs that are in a failed state based on the responses. the nf topology information is aggregated from operative nrfs should one or more of the nrfs still be operative.
