Abstract: 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.

Abstract: A method for locality-based selection and routing of network traffic to producer network functions (NFs) includes registering, by producer NFs, locality information with a network function registration function (NRF). The method further includes configuring, for each of a plurality of consumer NFs, locality preference rules. The method further includes detecting, by one of the consumer NFs, a need for a service provided by a plurality of different producer NFs, at least some of which are located in data centers with different localities. The method further includes selecting, by or on behalf of the one consumer NF and using the locality information registered for the producer NFs and the locality preference rules, a producer NF for providing the service to the one consumer NF.

Abstract: A method for service communications proxy (SCP)-specific prioritized producer network function (NF) discovery and routing includes maintaining, at the SCP, a producer NF latency database including SCP-specific producer NF latency information. The method further includes receiving a discovery request message or receiving a service request message having a 3GPP-Sbi-Discovery header and generating, at the SCP, a discovery request message in response to the received service request message and modifying, the discovery request message to include the SCP-specific producer NF latency information. The method further includes forwarding, by the SCP, the discovery request message to an NF repository function (NRF). The method further includes, at the NRF, creating a list of NF and their associated service profiles of producer NF instances and their respective producer NF service instances capable of providing the service identified in the discovery request message. The method further includes setting or adjusting, by the NRF and based on the SCP-specific producer NF latency information, priorities of NF and service profiles of producer NF and producer NF service instances in the list. The method further includes forwarding, by the NRF and to the SCP, a discovery response message including the list of NF and associated service profiles of producer NF instances and their respective producer NF service instances.

Abstract: A method for providing guaranteed minimum intermediate proxy node bandwidth for services includes configuring, at an intermediate proxy node, a guaranteed minimum bandwidth of the intermediate proxy node reserved to process messages associated with a service. The method further includes receiving a first message at the intermediate proxy node. The method further includes determining, by the intermediate proxy node, that the intermediate proxy node is in an overloaded state. The method further includes identifying, by the intermediate proxy node, the first message as being associated with the service for which the guaranteed minimum bandwidth is configured. The method further includes determining, by the intermediate proxy node, that a portion of the guaranteed minimum bandwidth for the service is available to process the first message. The method further includes routing, by the intermediate proxy node and to a producer network function (NF) that provides the service, the first message and updating a message count for the service.

Abstract: Various embodiments of the present technology generally relate to systems and methods for efficiently cleaning up resources within a network by bundling binding session audit requests. A binding support function (BSF) may determine support for bundled audit requests and unbundled audit requests at one or more policy control functions (PCFs) associated with potentially stale session binding records at the BSF. Based on audit support function at the PCF, the BSF may determine whether to bundle audit requests together, issue unbundled audit requests, or not issue any audit requests. PCF support for bundled or unbundled auditing may be provided via a network repository function (NRF), via headers in binding creation or update requests, or both.
