Abstract: A method for applying or overriding preferred locality criteria in processing NF discovery requests includes, at an NRF including at least one processor, maintaining an NF profiles database including NF profiles of producer NFs registered to provide service to other NFs, receiving, from an NF, an NFDiscover request including a preferred-locality attribute or lacking a preferred-locality attribute, accessing the NF profiles database to identify NF profiles of producer NFs capable of providing a service indicated by query parameters in the NFDiscover request, generating an NFDiscover response including the NF profiles identified as capable of providing the service indicated by the query parameters in the NFDiscover request, prioritizing the NF profiles in the NFDiscover response in a manner that overrides the preferred-locality attribute in the NFDiscover request or applies a preferred locality attribute selected by the NRF, and transmitting the NFDiscover response to the NF that transmitted the NFDiscover request.

Abstract: A method for discovering and tracking addresses associated with 4G service endpoints includes receiving, from a requesting node, a first domain name system (DNS) resolution or monitoring request including a fully qualified domain name (FQDN) of a 5G service endpoint. The method further includes querying a DNS server using the FQDN from the first DNS resolution request. The method further includes receiving, from the DNS server, a first response including an address associated with the 4G service endpoint and storing the address associated with the 4G service endpoint in a database. The method further includes communicating the address associated with the 4G service endpoint to the requesting node. The method further includes monitoring the FQDN for changes in address associated with the FQDN. The method further includes notifying the requesting node of the changes in address associated with the FQDN.

Abstract: A method for discovering and tracking addresses associated with producer network function (NF) service endpoints includes receiving a first domain name system (DNS) resolution request from a requesting node. The method further includes querying a DNS server using a fully qualified domain name (FQDN) extracted from the first DNS resolution request. The method further includes receiving a first response from the DNS server, the first response including an associated with a producer NF service endpoint associated with the FQDN and storing the address associated with the producer NF service endpoint in a database. The method further includes communicating the address associated with the producer NF service endpoint to the requesting node. The method further includes monitoring the FQDN for changes in address associated with the FQDN. The method further includes notifying the requesting node of the changes in address associated with the FQDN.

Abstract: A method for authenticating between network function (NF) repository functions (NRFs) across different networks includes receiving, at an NRF in a first network, a request message from an NRF in a second network separate from the first network. The method further includes determining, by the NRF in the first network, that the request message includes a roaming client credentials assertion (CCA) header. The method further includes, in response to determining that the request message includes a roaming CCA header, reading contents of the header. The method further includes authenticating the request message using the contents of the roaming CCA header. The method further includes, in response to successful authentication of the request message, generating a response message to the request message and transmitting the response message to the NRF in the second network.

Abstract: A method for applying or overriding a preferred-locality attribute during network function (NF) discovery includes, at a service communications proxy (SCP) or security edge protection proxy (SEPP) including at least one processor, receiving, from an NF, an NF discovery request including a preferred-locality attribute or lacking a preferred-locality attribute. The method further includes selecting, by the SCP or SEPP, a value for the preferred-locality attribute for the NF discovery request. The method further includes inserting, by the SCP or SEPP, the value for the preferred-locality attribute into the NF discovery request. The method further includes transmitting, by the SCP or SEPP, the NF discovery request to a network function repository function (NRF).

Abstract: Methods, systems, and computer readable media for managing network function (NF) request messages at a security edge protection proxy (SEPP) are disclosed. One method comprises receiving, by a SEPP and from an NF service consumer, an initial NF request message and obtaining a target NF type identifier, a requestor NF type identifier, and a network identifier from the initial NF request message. The method further includes utilizing the target NF type identifier, the requestor NF type identifier, and the network identifier to determine whether the initial NF request message is to be blocked by an associated service based interface at the SEPP and discarding, by the SEPP, the initial NF request message if the initial NF request message is determined to be blocked by the associated service based interface.

Abstract: Methods, systems, and computer readable media for limiting network function (NF) repository function (NRF) forwarding are disclosed. One example method for limiting NRF forwarding comprises: at a first NF comprising at least one processor: receiving a request message associated with a consumer NF; determining that the request message cannot be serviced by the first NF; inserting or modifying a forwarding limit value in the request message, wherein the forwarding limit value indicates a number of times that the request message can be forwarded; and forwarding the request message including the forwarding limit value toward a second NF.

Abstract: Methods, systems, and computer readable media for enabling forwarding of subsequent network function subscription updates. A method includes forwarding, from a bootstrapped network function repository function (NRF) in a first region, a subscription creation request from a consumer network function to a target NRF in a second region. The method includes creating, at the target NRF, a subscription for the consumer network function. The method includes generating, at the target NRF, a hint comprising data indicating one or more alternate NRFs each sharing subscription state data with the target NRF. The method includes sending, from the target NRF to the consumer network function, a subscription response message including the hint.

Abstract: A method for dynamically updating domain name system (DNS) records from network function (NF) profile information includes, at an NF repository function (NRF) including at least one processor, receiving a message relating to an NF profile of an NF. The method further includes constructing, based on NF service availability information in the NF profile and local configuration of the NRF, a DNS resource record for the NF. The method further includes utilizing a dynamic DNS update procedure to dynamically update a DNS resource record for the NF with a DNS server.
