A Network Repository Function (NRF) obtains status data from network functions in a geographic region. The NRF obtains additional status data for other network functions from another NRF in another geographic region. The NRF receives a request and identifies some of the network functions based on the request. The NRF prioritizes the identified network functions based on the status data. The NRF transfers a response that indicates the prioritized network functions.

Network function discovery through network repository functions in a wireless communication network

A solution for route selection includes receiving, by a network repository, from a first network function (NF), a query related to a target NF; querying, by the network repository, a route selection node for a shortest path to the target NF; receiving, by the network repository, from the route selection node, an indication of the shortest path to the target NF; and based on at least receiving the indication of the shortest path to the target NF, transmitting, by the network repository, to the first NF, a route to the target NF. In some examples, the shortest path has at least one of: a minimum number of hops, a minimum latency, a minimum jitter, and a minimum weighted transport score. In some examples, the route selection node is co-located with the network repository, which may be a network repository function (NRF).

A wireless communication network serves a wireless data service to a wireless User Equipment (UE). In the wireless communication network, a network controller receives a service request from a wireless UE and transfers a UE context request to a Unified Data Management (UDM). The UDM retrieves a subscriber profile for the wireless UE. The UDM identifies a wireless service type for the wireless UE and identifies a set of virtual Data Network Names (vDNNs) in the subscriber profile. The UDM selects one of the vDNNs for the wireless UE based on the wireless service type of the wireless UE. The UDM indicates the selected one of the vDNNs to the network controller. The network controller overrides provisioned DNN values using the selected one of the vDNNs. The network controller establishes a wireless data session for the wireless UE based on the selected one of the vDNNs.

Network function deregistration in wireless communication networks

Embodiments of the present disclosure are directed to systems and methods for improving wireless network services by carrying out various procedures to identify and filter suspect user devices. A network function may monitor a plurality of network service requests from a particular user device and determine, based on the plurality of network services requests, that the requesting user device is engaged in suspicious activity. Upon such a determination, the network function may initiate one or more enforcement actions by communicating an instruction to an equipment identity register to add the requesting user device to a suspect device list stored on a unified data repository.

Automated suspect device filtering on equipment identity registers

A wireless communication network receives a current message that relates to a user device for delivery to a network function. The network writes the current message to a queue. The network determines if the queue stores one or more prior messages that relate to the user device. The network transfers the current message from the queue for delivery to the network function when the queue does not store the one or more prior messages for the user device. When the queue for the user device does store the one or more prior messages for the user device, the network prioritizes the current message and the one or more prior messages by network function type and transfers the current message and the one or more prior messages that relate to the user device from the queue for delivery to the network function based on the prioritization.
