    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: A method for providing updated network slice information to a network slice selection function (NSSF includes registering, by a network slice management function (NSMF) with a network function (NF) repository function (NRF), an NF profile corresponding to the NSMF and subscribing, by the NSMF with the NRF, for status updates corresponding to NF instances belonging to network slice instances created by the NSMF. The method further includes receiving, by the NSMF from the NRF, a notification message including one or more network traffic load level updates related to at least one of the NF instances, processing the one or more network traffic load level updates to generate network slice instance configuration information for at least one of the network slice instances, and providing, by the NSMF, the network slice instance configuration information to a NSSF managing the at least one of the network slice instances.

    Abstract: Methods, systems, and computer readable media for Diameter-peer-wide egress rate limiting include a process performed at a Diameter relay agent (DRA) and at a rate limiting policer. The process includes receiving service requests from Diameter-based consumers and forwarding the service requests to DRA worker instances. The process further includes, at the DRA worker instances, requesting, from the rate limiting policer, which is separate from the DRA worker instances, Diameter peer capacity for handling the service requests. The process includes, at the rate limiting policer, performing Diameter-peer-wide egress rate limiting between the DRA worker instances and Diameter peer instances by granting or denying requests for Diameter peer capacity from the DRA worker instances such that combined egress traffic from the DRA worker instances does not exceed rate capacities of the Diameter peers.

    IPC: H04L29/12

    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: Methods, systems, and computer readable media for discovering network function (NF) service producers in a hierarchical network are disclosed. One method includes receiving, by a regional NF repository function (NRF) operating in a first region of a hierarchical network, a NF registration request message from a NF service producer operating in the first region and detecting, by the regional NRF, an absence of Info and/or InfoList attribute data in the received NF registration request message. The method further includes creating, by the regional NRF, an entry in NrfInfo structure information directed toward a root NRF operating in the hierarchical network, wherein the entry includes an nfinstance identifier that identifies the NF service producer and is mapped to an empty structure field indicative of absent Info and/or InfoList attribute data and sending, by the regional NRF to the root NRF, the NrfInfo structure information via a registration message or update registration message.

    Abstract: Methods, systems, and computer readable media for restricting a number of hops conducted in a communications network are disclosed. One method includes receiving, by a hypertext transfer protocol (HTTP) proxy element in a first network region, a service request message including a header section that specifies a maximum number of hops value and conducting a search for a producer network function (NF) in the first network region to provide a network service requested in the service request message. The method further includes determining the maximum number of hops value in the header section of the service request message if the HTTP proxy element is unable to locate the producer NF in the first network region, reducing the maximum number of hops value in the header section of the service request message by one to derive an updated maximum number of hops value if the HTTP proxy element determines that the maximum number of hops value in the header section is greater than zero, and directing the service request message containing the updated maximum number of hops value to a second HTTP proxy element located in a second network region.
