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 HTTP stream tuning during load and overload control includes, at a first NF, determining a load/overload level of the first. The method further includes determining an initial value for an HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter. The method further includes publishing the initial value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter to a second NF that sends traffic to the first NF. The method further includes determining that the load/overload level of the first NF has changed. The method further includes, in response to determining that the load/overload level has changed, adjusting the value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter based on the load/overload level and a direction of change in the load/overload level. The method further includes publishing the adjusted value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter to the second NF.

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 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 discovery or service 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 discovery request message.

Abstract: A method for monitoring IoT device state includes, in an SCEF implemented using at least one processor. The method includes providing a common interface for receiving subscription requests from IoT ASs and SCSs for monitoring state of IoT devices of plural different generation networks. The method further includes maintaining, in the SCEF, a database of identifiers of IoT devices of a first-generation network, providing, in the SCEF, an interface to a subscriber data repository node of the first-generation network, and receiving, via the common interface, a subscription request for subscribing to receive updates in state information for an IoT device. The method further includes performing a lookup in the database and identifying the subscription request as being associated with an IoT device registered in the first-generation network and transmitting a message to the subscriber data repository node of the first-generation network for receiving state information regarding the IoT device.

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: The technology disclosed herein enables redistribution of connections among service instances by determining a subset of the connections and terminating the subset. In a particular example, a method includes identifying the application-layer connections established between service instances and peers and identifying a high-load service instance of the service instances. A number of the application-layer connections established with the high-load service instance satisfies load criteria. The method further includes determining a subset of connections from a portion of the application-layer connections connected to the high-load service instance and terminating the subset of connections.

Abstract: 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.

Abstract: A method for handling hacker intrusion in NF profile management at an NRF includes receiving, at the NRF and from a consumer NF, an NF register request message including an NF profile of the consumer NF, setting and storing an NF profile version number for the NF profile, and communicating the NF profile version number to the consumer NF. The consumer NF stores the NF profile version number and transmits a request for initiating an NF update or NF heart-beat service operation to the NRF. The NRF receives the request for initiating the NF update or NF heart-beat service operation, increments the NF profile version number, and communicates the incremented NF profile version number to the consumer NF. The consumer NF receives the incremented NF profile version number, determines that an NF profile version mismatch has occurred, and, in response, initiates an NF profile corrective action with the NRF.

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.

Abstract: 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.
