Abstract: Methods, systems, and computer readable media for notification delivery are disclosed. One example method for notification delivery comprises: at a network function including at least one processor: receiving a first message indicating that first notification data is available for a first notification receiver; determining, during an overload or congestion condition, that a computed priority value for a first notification message associated with the first message indicates an acceptable priority value for delivery during the overload or congestion condition, wherein the computed priority value is computed using a first priority value associated with the first notification message and a minimum priority value and a maximum priority value associated with the first notification receiver and/or a first service type; and sending the first notification message to the first notification receiver.

Abstract: A method for supporting configurable producer network function (NF) Internet protocol (IP) address mappings includes, at an NF repository function (NRF), receiving, from a requesting node, a request message for network address and/or service information of a producer NF. The method further includes determining, from the request message, at least one consumer NF parameter. The method further includes using the at least one consumer NF parameter, a producer NF IP address mapping rule. The method further includes, in response to locating the producer NF IP address mapping rule, determining, using the producer NF IP address mapping rule, an IP address to return to the requesting node. The method further includes generating a response message including the IP address and transmitting the response message to the requesting node.

Abstract: A method for updating network function profiles in a telecommunications network includes registering, by a producer network function, a network function profile with a network function repository function (NRF), the network function profile specifying at least one serving scope or discoverable parameters by consumer NFs. The method includes determining that a load level of the producer network function has exceeded a first threshold. The method includes, in response to determining that the load level of the producer network function has exceeded the first threshold, updating the network function profile at the NRF to reduce the serving scope.

Abstract: Methods, systems, and computer readable media for registering application functions (AFs) using common application programming interface (API) framework (CAPIF) are disclosed. One example method for registering AFs using CAPIF comprises: at a CAPIF node comprising at least one processor: receiving, from an AF, a registration trigger message comprising information about the AF; determining that the registration trigger message is valid; generating a custom NF registration message using the information about the AF; and sending the custom NF registration message to an NF repository function (NRF).

Abstract: A method for sharing key identification (key ID) and public certificate data for access token verification comprises, at a network function (NF) repository function (NRF) including at least one processor, receiving, from a producer NF, an NF registration message including key ID version information. In response to detecting the key ID version information, sending, to the producer NF, an NF registration response message including a current key ID version value, at least one digital certificate, and at least one corresponding public key to the producer NF. The method further includes receiving, from the producer NF, an NF update message that includes the current key ID version value and in response to determining that the current key ID version value in the NF update message does not match an updated key ID version value maintained at the NRF, sending an NF update response message that the updated key ID version value, at least one updated digital certificate, and at least one corresponding updated public key to the producer NF.

Abstract: Methods, systems, and computer readable media for resource cleanup in communications networks are disclosed. One method for resource cleanup in a communications network comprises: at a policy control function (PCF) comprising at least one processor: receiving, from a binding support function (BSF), a first notification indicating a potentially stale or inactive first binding record, wherein the first notification includes context data associated with the first binding record; determining that resource cleanup associated with the first binding record should be performed; and initiating, using the context data, resource cleanup associated with the first binding record at one or more network entities.

Abstract: A method for rules-based overload control for 5G services includes configuring, at an intermediate or a producer network function (NF), overload message handing rules, wherein at least some of the rules include destination network name (DNN), network subscription, network location, or a network slice identifying parameter or any parameter/attribute defined by 3GPP/vendor as rule selection criteria. The method includes a guaranteed processing bandwidth of the intermediate or producer NF with at least some of the overload message handling rules, receiving a first message at the intermediate or producer NF, determining that an overload condition exists, identifying that the first message includes parameters that match the rule selection criteria for one of the overload message handling rules, determining, that a portion of the guaranteed processing bandwidth of the intermediate or producer NF for the matching overload message handling rule is available to process the first message, processing the first message, and updating a message count for the overload message handling rule.

Abstract: A method for optimized NF discovery and routing includes, at an SCP, receiving a discovery request message or generating a discovery request message in response to a received service request message with a 3gpp-Sbi-Discovery header. The SCP modifies the discovery request message to identify as unhealthy at least one service endpoint and service name combination associated with at least one producer NF instance capable of providing a service identified in the discovery request message or the service request message The SCP forwards the modified discovery request message to the NRF. The NRF creates a list of service profiles of producer NF instances capable of providing the service identified in the modified discovery request message and excludes, from the list, at least one service profile of the at least one producer NF instance corresponding to the endpoint and service name combinations identified as unhealthy in the modified discovery request message.

Abstract: A method for network function (NF) topology synchronization includes, at a network node including at least one processor, maintaining NF instance identifiers and corresponding NF profile version identifiers in an NF topology database local to the network node, the NF profile version identifiers indicating most current NF profile versions stored by the network node for each NF instance identifier. The method further includes obtaining a list of NF instance identifiers and NF profile version identifiers from an NF repository function (NRF), accessing the NF topology database, determining, by comparing the NF profile version identifiers in the list with NF profile version identifiers for corresponding NF instance identifiers in the NF topology database, whether the NF profiles stored by the network node are lagging behind the NF profiles stored by the NRF, and auditing or refraining from auditing the NRF for updated NF profiles based on results of the comparison.

Abstract: A method for handling multiple instances of a service provided by one or more producer network functions (NFs) includes, at a service based architecture (SBA) platform including at least one processor and a memory, obtaining first and second application programming interface (API) version indicators associated with first and second service instances implemented by one or more producer NFs. The method further includes decoding the first and second API version indicators. The method further includes detecting, based on results of the decoding, multiple instances of the same service and that a first service instance is backward compatible with a second service instance. The method further includes implementing canary testing of the first service instance.
