    Abstract: A method for distributing network function (NF) high availability (HA) topology information in a core network includes, at an NF repository function (NRF) including at least one processor, receiving, from a plurality of producer NFs in an NF set, NFRegister requests including NF HA topology information for the producer NFs. The method further includes registering the producer NFs and storing the NF HA topology information for the producer NFs. The method further includes receiving, from a consumer NF or service communication proxy (SCP), an NFDiscover request containing at least one service discovery parameter that corresponds to a service provided by the producer NFs. The method further includes responding to the NFDiscover request by generating an NFDiscover response, including, in the NFDiscover response, the NF HA topology information for the producer NFs, and transmitting the NFDiscover response to the consumer NF or SCP.

    Abstract: A method for resource object level authorization at a network function (NF) includes maintaining, by a first NF, a service based interface (SBI) resource object access authorization policy database containing policies for controlling access to SBI resource objects and dynamically populating a resource object owner database containing records for resource objects and corresponding resource object owners. The method further includes receiving, by the first NF and from a second NF, a first SBI resource object access request for accessing a resource object, accessing, using information from the first SBI resource object access request, the resource object access authorization policy database and the resource object owner database, determining that an access to the resource object requested by the first resource object access request is not permitted, and preventing the access to the resource object requested by the first resource object access request.

    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: The subject matter described herein includes a method for reducing the likelihood of successful denial of service (DoS) attacks by validating overload control information (OCI) scope information against network function (NF) profile information obtained using target resource identification information. The method includes receiving a service based interface (SB I) request message, obtaining, from the SBI request message, target resource identification information, obtaining NF profile information using the target resource identification information and storing the NF profile information, receiving an SBI response message including overload control information and scope information for the overload control information, using the stored NF profile information to determine whether the scope information for the overload control information is valid, and, in response to determining that the scope information for the overload control information is invalid, rejecting the SBI response message.

    Abstract: A method for generating network function (NF) set load information aware NF discovery responses includes, at an NF repository function (NRF), receiving NFUpdate messages from producer NF instances. The method further includes collecting or generating, from the NFUpdate messages, NF set load information for NF sets of which the producer NF instances are members. The method further includes receiving, from a consumer NF, an NF discovery request. The method further includes generating, using query parameters in the NF discovery request, an NF discovery response including NF profiles of producer NF instances corresponding to the query and, including, in the NF discovery response, NF set load information for NF sets of producer NF instances whose NF profiles are included in the NF discovery response. The method further includes forwarding the NF discovery response including the NF set load information to the consumer NF.
