    Abstract: Methods, systems, and computer readable media for processing binding requests in a telecommunications network. A method includes receiving, at a binding support function (BSF), a first request to create a first binding between a protocol data unit (PDU) session and a first policy and control function (PCF). The method includes creating, at the BSF, the first binding between the PDU session and the first PCF and storing, with the first binding, a first PCF session acceptance timestamp from a first header of the first request. The method includes receiving, at the BSF, a second request to create a second binding between the PDU session and a second PCF. The method includes determining, at the BSF, whether to accept or reject the second request based on a difference between the first PCF session acceptance timestamp and a second PCF session acceptance timestamp from a second header of the second request.

    Abstract: A method for generating and processing bundled notification request messages includes, at a producer NF, receiving subscription request messages from consumer NFs via one or more SCPs. The method further includes obtaining and storing, from the subscription request messages validated by the producer NF, identities of SCPs within a last N hops of SCPs from the producer NF, N being an integer of at least one. The method further includes detecting an event requiring notifications to a plurality of the consumer NFs. The method further includes identifying, from the SCPs within the last N hops of SCPs from the producer NF, a group of SCPs for which the notifications can be bundled. The method further includes generating a bundled notification request message for the group of SCPs for which the notifications can be bundled. The method further includes transmitting the bundled notification request message to a first-hop SCP in the group of SCPs.

    Abstract: Methods, systems, and computer readable media for supporting mobile originated data multicasting in a communications network are disclosed. One method includes receiving, from a consumer network function (NF) in a communications network, a deliver request message containing mobile originated (MO) data corresponding to a protocol data unit (PDU) session, wherein NIDD context information stored at NEF and referred by a context identifier in the deliver request message includes a subscriber identifier and a data network identifier associated with a user device requesting the PDU session and determining that a rule entry belonging to a plurality of rule entries contained in a multicasting ruleset matches at least one of the subscriber identifier and the data network identifier included in the NIDD context information that is stored at the NEF and referred by the context identifier in the deliver request message. The method further includes accessing a list of NF identity objects in the rule entry in response to determining the rule entry matches at least one of the subscriber identifier and/or the data network identifier and delivering the MO data to each of a plurality of NF endpoints specified in the rule entry in accordance with a routing condition indicated in each of the NF identity objects respectively associated with each of the NF endpoints.

    Abstract: A method for preferred network function (NF) location based routing using a service communication proxy (SCP) includes receiving a service request message from a consumer NF. The method further includes performing, by an SCP, a lookup in a preferred NF location routing rules database at the SCP using at least one parameter extracted from the service request message. The method further includes locating, by the SCP and in the preferred NF location routing rules database, a preferred NF location routing rule corresponding to the at least one parameter extracted from the service request message. The method further includes selecting, by the SCP, a producer NF to process the service request based on application of the preferred NF location routing rule. The method further includes routing, by the SCP, the service request message to the producer NF.

    Abstract: A method for service communication proxy (SCP)-specific prioritized producer network function (NF) discovery and routing includes maintaining, at the SCP, a producer NF latency database including SCP-specific producer NF latency information. The method further includes receiving a discovery request message or receiving a service request message having a 3GPP-Sbi-Discovery header and generating, at the SCP, a discovery request message in response to the received service request message and modifying, the discovery request message to include the SCP-specific producer NF latency information. The method further includes forwarding, by the SCP, the discovery request message to an NF repository function (NRF). The method further includes, at the NRF, creating a list of NF and their associated service profiles of producer NF instances and their respective producer NF service instances capable of providing the service identified in the discovery request message. The method further includes setting or adjusting, by the NRF and based on the SCP-specific producer NF latency information, priorities of NF and service profiles of producer NF and producer NF service instances in the list. The method further includes forwarding, by the NRF and to the SCP, a discovery response message including the list of NF and associated service profiles of producer NF instances and their respective producer NF service instances.
