Methods, systems, and computer readable media for service communication proxy (SCP) routing are disclosed. One example method for SCP routing comprises: at a first SCP associated with a first domain, the first SCP including at least one processor: receiving a first request destined for a network function; determining that the first request lacks routing path information for the first request; generating, using SCP domain routing information obtained from a network function repository function (NRF), a sequence of domains usable for routing the first request to the network function; adding, to the first request, the routing path information indicating the sequence of domains; determining, using the routing path information or the sequence of domains, a second SCP for routing the first request; and sending the first request comprising the routing path information to the second SCP.

A method for integrity protection for subscribe/notify and NF discovery transactions between an NF and an NRF includes receiving, from the NF, a subscribe or discovery request message, determining that the subscribe or discovery request message includes at least one indicator requesting NRF communications integrity protection, and computing an integrity check value of at least a portion of the subscribe or discovery request message and comparing the computed integrity check value to an integrity check value included in the subscribe or discovery request message. The method further includes determining that the computed integrity check value matches the integrity check value included in the subscribe or discovery request message, and formulating a response to the subscribe or discovery request message, generating and adding at least one digital signature to the response message, and transmitting the response message to the NF.

Methods, systems, and computer readable media for synchronization of policy data between network functions in telecommunications networks. A method includes receiving, at a first network function in a telecommunications network, a subscription request from a second network function. The subscription request specifies a subscription for updates to policy data objects maintained by the first network function. The method includes sending a notification response to the second network function. The notification response includes, for each policy data object, a custom header including a respective entity tag for the policy data object. The method includes receiving a resource request from the second network function. The resource request specifies a first policy data object and includes a first entity tag for the first policy data object. The method includes sending a synchronization result to the second network function specifying whether or not the entity tag match.

Methods, systems, and computer readable media for reporting a reserved load to a network function in a communications network are disclosed. One method includes determining, by a NF service producer, a current compute load metric value for the NF service producer operating in a communications network and detecting a number of active sessions supported at the NF service producer. The method further includes deriving a reserved compute load metric value corresponding to a predicted number of subsequent service requests at the NF service producer based on the number of active sessions and a predictive reserved load percentage value and calculating an adjusted reported compute load metric value amounting to a sum of the current compute load metric value and the reserved compute load metric value.

A method for generating and processing bundled notification request messages includes, at a producer NF, receiving subscription request messages from consumer NFs via one or more SCPs. The method further includes obtaining and storing, from the subscription request messages validated by the producer NF, identities of SCPs within a last N hops of SCPs from the producer NF, N being an integer of at least one. The method further includes detecting an event requiring notifications to a plurality of the consumer NFs. The method further includes identifying, from the SCPs within the last N hops of SCPs from the producer NF, a group of SCPs for which the notifications can be bundled. The method further includes generating a bundled notification request message for the group of SCPs for which the notifications can be bundled. The method further includes transmitting the bundled notification request message to a first-hop SCP in the group of SCPs.
