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: 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.

Abstract: A method for overload and flow control at a service capability exposure function (SCEF) includes providing for configuration of, in memory accessible by the SCEF, at least one of user equipment (UE), service capability server (SCS), application server (AS), and application programming interface (API) gateway specific message priority rules. The method further includes providing for configuration of, in the memory accessible by the SCEF, at least one of SCS, AS, and API gateway capacity information. The method further includes throttling message traffic at the SCEF based on the at least one of UE, SCS, AS, and API gateway specific message priority rules and the at least one of SCS, AS, and API gateway capacity information.

Abstract: A method includes receiving a first message associated with a first machine type communications (MTC) device; sending an authentication request associated with the first MTC device to a home subscriber server (HSS), wherein the authentication request requests a validated time period indicating an amount of time that authentication associated with the first MTC device is valid; and receiving, from the HSS, an authentication response, wherein the authentication response indicates the validated time period.

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.

Abstract: A method for identifying alternate delivery endpoints for mobile originated data and monitoring reports in a communications network includes establishing, by a network exposure function (NEF) in a communications network, priority rules in a priority configuration database that define routing priority indicators corresponding to a plurality of applications functions (AFs) and receiving a service request or notification request message directed to one of the plurality of AFs from a consumer network function (NF) in the communications network. The NEF accesses a context database to validate context information associated with a destination AF belonging to the plurality of AFs. If the destination AF is unavailable or is not in proximity to the NEF, an event notification request message associated with the service request or notification request message is directed to a prioritized AF specified in the priority configuration database, wherein the prioritized AF is a peer of the destination AF.

Abstract: The technology disclosed herein enables redistribution of connections between service instances by determining a subset of the connections and terminating the subset. In a particular example, a method includes determining connection information about connections established with service instances operating in an active-active configuration. The connection information identifies directions of connection initiation for the connections and identifies peers for the connections. Based on the connection information, the method includes determining a subset of the connections for reestablishment on a per-peer basis using direction-dependent criteria and terminating the subset of the connections.

Abstract: According to another aspect of the subject matter described herein, includes receiving or generating a service based interface (SBI) request message. The method further includes identifying a next-hop network function (NF) of the SBI request message. The method further includes determining, from a registered profile of the next-hop NF, whether the next-hop NF supports handling of encrypted SBI request message parameters. The method further includes in response to determining that the next-hop NF supports handling of encrypted SBI request message parameters: encrypting selected SBI request message parameters; adding one or more headers to the SBI request message or updating one or more headers in the SBI request message to facilitate identification and decryption of the encrypted SBI request message parameters; and transmitting the SBI request message to the next-hop NF.

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: Methods, systems, and computer readable media for service communication proxy (SCP) routing are disclosed. One example method for SCP routing comprises: at a first SCP associated with a first domain, the first SCP including at least one processor: receiving a first request destined for a network function; determining that the first request lacks routing path information for the first request; generating, using SCP domain routing information obtained from a network function repository function (NRF), a sequence of domains usable for routing the first request to the network function; adding, to the first request, the routing path information indicating the sequence of domains; determining, using the routing path information or the sequence of domains, a second SCP for routing the first request; and sending the first request comprising the routing path information to the second SCP.
