Abstract: A method for processing NF discovery requests using prioritized lists of preferred locations includes maintaining an NF profiles database including NF profiles of producer NFs registered to provide service to other NFs and a preferred locality attribute mappings database including mappings between preferred locality attributes and prioritized lists of preferred locations. The method includes receiving, from an NF, an NF discovery request including query parameters and a preferred locality attribute. The method further includes accessing the preferred locality attribute mappings database using the preferred locality attribute and obtaining a prioritized list of preferred locations corresponding to the preferred locality attribute, accessing the NF profiles database using the query parameters and identifying NF profiles of producer NFs capable of providing a service indicated by the query parameters, and prioritizing the NF profiles according to the prioritized list of preferred locations. An NF discovery response is generated and transmitted to the NF.

Abstract: A method for obtaining and maintaining Internet protocol (IP) address pools and using the IP address pools to respond to IP address allocation requests from service management functions (SMFs) includes, at an IP address provider microservice implemented using at least one processor, obtaining from dynamic host configuration protocol (DHCP) servers, a plurality of IP addresses and corresponding IP address leases and storing the IP addresses in IP address pools. The steps further include maintaining the IP address leases. The method further includes receiving, from an SMF, a request for allocation of an IP address. The method further includes allocating one of the IP addresses from one of the pools to the SMF. The method further includes communicating the IP address to the SMF.

Abstract: A method for policing APN-AMBR includes, at P-GW including plural P-GW DP worker instances: receiving, uplink data to be transmitted over a non-GBR bearer associated with a first PDN session from a first UE via an AP or downlink data to be transmitted over the non-GBR bearer to the first UE via the AP; forwarding the uplink or downlink data to a first P-GW DP worker instance of the plurality of P-GW DP worker instances that is assigned to the PDN session; and, at the first P-GW DP worker instance, transmitting, to an APN-AMBR policer separate from the P-GW, a request for a slice of APN-AMBR capacity for processing the uplink or downlink data. The method further includes, at the APN-AMBR policer: maintaining records of APN-AMBR capacity used by UEs having PDN sessions assigned to different ones of the P-GW DP worker instances; and granting or denying the request based on the APN-AMBR capacity used by the PDN sessions assigned to the different ones of the P-GW DP worker instances.

Abstract: A method for distributing Sigtran connections among signal transfer point (STP) message processors includes providing a connection load balancer as a front end to plural message processors of an STP. The method further includes publishing, by the connection load balancer, an Internet protocol (IP) address to SS7 peers. The method further includes initializing the message processors of the STP to listen on the IP address published by the connection load balancer. The method further includes receiving, at the connection load balancer, a Sigtran message addressed to the IP address. The method further includes determining, by the connection load balancer, whether the Sigtran message is an initial message for a Sigtran connection or a subsequent message for a Sigtran connection and whether the Sigtran connection has been assigned to one of the message processors. The method further includes forwarding the message to one of the message processors or dropping the message based on whether the message is an initial message or a subsequent message and based on whether the connection has been assigned to one of the message processors.

Abstract: A method for selecting NF profiles of NF set mates for alternate routing includes receiving an NF discovery request, accessing an NF profiles database, and identifying NF profiles that match query parameters in the NF discovery request. The method further includes determining a value of an NF profiles limit parameter, selecting a first number of NF profiles that is less than the value of the NF profiles limit parameter, selecting a second number of NF profiles, wherein the NF profiles in the second number of NF profiles correspond to NF set mates of NFs corresponding to NF profiles in the first number of NF profiles and a sum of the first and second numbers number is less than or equal to the value of the NF profiles limit parameter, and generating and transmitting an NF discovery response including the NF profiles in the first and second numbers of NF profiles.

Abstract: A method for avoiding sending duplicate notifications for overlapping subscriptions includes, at a network function (NF) repository function (NRF), detecting an event relating to an NF. The method further includes identifying a plurality of subscriptions having a subscription condition corresponding to the event. The method further includes generating a list of the plurality of subscriptions having a subscription condition corresponding to the event. The method further includes iterating through the list of subscriptions and identifying overlapping subscriptions. The method further includes removing the overlapping subscriptions from the list. The method further includes sending notification messages to NFs corresponding to subscriptions remaining in the list.

Abstract: A method for using a network function (NF) repository function (NRF) for mapping single network slice selection assistance information (S-NSSAI) includes, storing at an NRF in a first network, an S-NSSAI mapping database including mappings between S-NSSAI values of the first network and S-NSSAI values of other networks. The method further includes receiving, from a requesting NF in a second network, a request message including a requester S-NSSAI attribute including an S-NSSAI value of the second network. The method further includes performing a lookup in the S-NSSAI mapping database and locating a mapping between the S-NSSAI value of the second network and the S-NSSAI value of the first network. The method further includes generating a response message including the S-NSSAI value of the first network. The method further includes transmitting the response message to the requesting NF in the second network.

Abstract: Various embodiments of the present technology generally relate to systems and methods for providing a positive resource discovery response for a suspended resource. More specifically, some embodiments relate to monitoring an availability status of resources within a network. If a connection between a resource and a monitoring element is interrupted, the status of the resource may be set to “suspended”. However, the interruption may be temporary or localized in nature, and the resource may still be available to service requests. Accordingly, when the monitoring element receives a resource discovery request for resources that all have the “suspended” status, the monitoring element may return a discovery response identifying the suspended resources as available instead of providing a response indicating no available resources.

Abstract: A regional NRF may register NFs, and the registration information may include locality information for each registered NF. During synchronization with a root NRF, the regional NRF provides the locality information for each registered NF. During discovery request routing by the root NRF, the root NRF prioritizes regional NRFs having NFs that satisfy the discovery parameters of the discovery request and match the preferred locality indicated in the discovery request.

Abstract: A method for applying or overriding preferred locality criteria in processing NF discovery requests includes, at an NRF including at least one processor, maintaining an NF profiles database including NF profiles of producer NFs registered to provide service to other NFs, receiving, from an NF, an NFDiscover request including a preferred-locality attribute or lacking a preferred-locality attribute, accessing the NF profiles database to identify NF profiles of producer NFs capable of providing a service indicated by query parameters in the NFDiscover request, generating an NFDiscover response including the NF profiles identified as capable of providing the service indicated by the query parameters in the NFDiscover request, prioritizing the NF profiles in the NFDiscover response in a manner that overrides the preferred-locality attribute in the NFDiscover request or applies a preferred locality attribute selected by the NRF, and transmitting the NFDiscover response to the NF that transmitted the NFDiscover request.
