Patent ID: 11611626

Abstract:
A method for distributing network function (NF) high availability (HA) topology information in a core network includes, at an NF repository function (NRF) including at least one processor, receiving, from a plurality of producer NFs in an NF set, NFRegister requests including NF HA topology information for the producer NFs. The method further includes registering the producer NFs and storing the NF HA topology information for the producer NFs. The method further includes receiving, from a consumer NF or service communication proxy (SCP), an NFDiscover request containing at least one service discovery parameter that corresponds to a service provided by the producer NFs. The method further includes responding to the NFDiscover request by generating an NFDiscover response, including, in the NFDiscover response, the NF HA topology information for the producer NFs, and transmitting the NFDiscover response to the consumer NF or SCP.
