Abstract: A method for extending new radio (NR) usage indications to an application function (AF) includes, at a policy and charging rules function (PCRF) including at least one processor, receiving an indication of NR usage by a user equipment (UE). The steps further include determining that an AF is subscribed to receive indications of NR usage for the UE. The steps further include, in response to determining that an AF is subscribed to receive indications of NR usage for the UE communicating the indication of NR usage to the AF. The steps further include receiving a message from the AF to effect a change in service provided to the UE based on the indication of NR usage. The steps further include effecting the change in service provided to the UE based on the indication of NR usage.

Abstract: A method for resolving priorities among network function (NF) instances includes, at a priority resolver implemented using at least one processor, providing a priority resolution application programming interface (API) that allows NF instances to request priority resolution. The method further includes receiving, via the API and from a plurality of NF instances, requests for priority resolution. The method further includes using a priority resolution algorithm to determine a relative priority for each of the NF instances. The method further includes generating and transmitting to each of the NF instances a priority resolution response including the relative priority determined for the NF instance.

Abstract: A method for establishing message priority in network slices based on quality of service (QoS) parameters includes receiving, by a network slice configuration service provider entity and from a network slice management service provider entity, a network slice creation notification message containing at least a QoS profile corresponding to a created network slice, utilizing the QoS profile to derive a service based interface (SBI) message priority (SMP) associated with the network slice, and providing the SMP to a requesting access and mobility management function (AMF) entity in response to receiving a network slice selection request message from the AMF entity, wherein the AMF entity assigns the SMP level value to network traffic directed to the network slice.

Abstract: A method for autonomously generating network function test cases includes detecting a failure case in a network function of a core network of a telecommunications network. The method includes, in response to detecting the failure case, autonomously generating a network function test case based on the failure case. The network function test case includes one or more network status parameters detected when detecting the failure case. The method includes supplying the network function test case to a network testing system configured for executing the network function test case by repeating the one or more network status parameters and determining whether or not the network function repeats the failure case.

Abstract: A method for supporting multiple locations in a preferred-locality attribute NF discovery and selection includes receiving, from producer NFs, NF registration messages including NF profiles with locality attributes and registering the producer NFs by storing the NF profiles including the locality attributes in an NF registration database local to an NRF. The method further includes receiving, from a requesting NF, an NF discovery request having query parameters for discovering producer NFs, the query parameters including a preferred-locality attribute identifying a plurality of different preferred producer NF locations. The method further includes retrieving NF profiles from the NF registration database having locality attributes that match any of the preferred producer NF locations. The method further includes generating an NF discovery response including the NF profiles retrieved from the NF registration database. The method further includes forwarding the NF discovery response to the requesting NF.

Abstract: Methods, systems, and computer readable media for rank processing in network function selection. A method includes periodically receiving, at a network function discovery node, and from each producer network function of a number of producer network functions, a current load value specifying a computing load carried by the producer network function. The network function discovery node is configured for performing service discovery between network functions of a telecommunications core network. The method includes determining, for each producer network function, an available capacity for the producer network function based on the current load value and a published capacity of the producer network function. The method includes responding to a network function discovery request from a consumer network function using the available capacity of each producer network function.

Abstract: A method for dynamically provisioning and using PLMN location mappings includes, in an SCEF or NEF, receiving, from a PLMN network node, a message containing a PLMN location identifier and a non-PLMN location identifier, extracting the PLMN location identifier and the non-PLMN location identifier from the message and storing, in a PLMN location mapping database in the SCEF or NEF, a mapping between the PLMN location identifier and the non-PLMN location identifier. The method further includes receiving, via a monitoring interface of the SCEF or NEF, a monitoring request message requesting IoT device information and including a non-PLMN location identifier. The method further includes locating an entry in the PLMN location mapping database corresponding to the non-PLMN location identifier, extracting a PLMN location identifier from the database, using the PLMN location identifier extracted from the database to obtain IoT device information, and responding to the monitoring request message with the IoT device information.
