Systems, methods and devices are provided for subscriber prioritization upon initial attachment. Methods include receiving notification of an initial attach request from a wireless device at a subscriber locator function (SLF) and performing a database lookup at the SLF. Methods further include obtaining a subscriber priority from the database lookup and transmitting the subscriber priority from the SLF to a network component responding to the initial attach request from the wireless device.

Initial attach priorization method and system

A wireless communication network serves a User Equipment (UE) based on geographic coordinates for the UE. The wireless communication network exchanges authentication data with the UE and authenticates an identity of the UE. The wireless communication network obtains the geographic coordinates from the UE in response to authenticating the identity of the UE. The wireless communication network determines UE context for the UE based on the geographic coordinates for the UE. The wireless communication network exchanges user data with the UE based on the UE context. The wireless communication network receives a location request for the UE and responds to the location request with the geographic coordinates for the UE.

Systems, methods, and devices that relate to the improvement of controlling impersonating attacks from foreign networks are disclosed. In one example aspect, a method for wireless communication includes receiving, by a policy control node, a request message from a first network node. The request message comprising a first identifier indicating a first public land mobile network associated with an establishment of a bearer or a session for a terminal device. The method includes transmitting a query to a second network node in the core network to obtain a second identifier of a second public land mobile network associated with a registration of the terminal device. The method also includes accepting or rejecting, by the policy control node, the establishment of the bearer or the session for the terminal based on whether the first identifier matches the second identifier.

Identification of fraudulent network data sessions

A wireless communication system serves a wireless User Equipment (UE) over a wireless network slice. A serving wireless communication network selects a Uniform Data Repository (UDR) in a target wireless communication network based on the wireless network slice. The serving wireless communication network transfers an information request for the wireless UE across a wireless communication network boundary to the selected UDR in the target wireless communication network. In response to the information request, the selected UDR in the target wireless communication network transfers UE information for the wireless UE across the wireless communication network boundary to the serving wireless communication network. The wireless network slice in the serving wireless communication network serves the wireless UE based on the UE information.

Unified data repository (UDR) access across wireless communication networks

An Internet Protocol Multimedia Subsystem (IMS) uses IMS slices in association with wireless network slices. The IMS receives an IMS registration from an IMS user device. In response, a wireless communication network identifies the wireless network slice that currently serves the IMS user device. The wireless communication network and/or the IMS selects an IMS slice for the IMS user device based on the wireless network slice that currently serves the IMS user device. The IMS serves an IMS service to the IMS user device from the selected IMS slice over the identified wireless network slice.

Internet protocol multimedia subsystem (IMS) slicing

Systems and methods are provided for controlling device retry behavior. The method is performed by receiving an error code generated in response to a resource request from the wireless device, associating the error code with a timeframe for resending the resource request from the wireless device, and sending the error code and the timeframe to the wireless device in response to the resource request.

Method and system for optimizing device retry behavior

Embodiments of the present disclosure are directed to systems and methods for group-based filtering of user devices on a wireless network. Upon a request from a user device to access a requested network service, a device specific identifier associated with the user device is used to determine one or more groups associated with the user device. Based on any access restrictions for the one or more groups associated with the user device, the requested network service may be selectively authorized or provided.

Network access based on device type

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).

Intelligent route selection for low latency services

Performing hybrid synchronization of databases in a telecommunication network is described herein. Management and replication of different types of data stored in the databases can be performed differently. Provisioning data stored in the databases can be managed differently from session data stored in the databases. The provisioning data can be managed utilizing synchronous synchronization. The session data can be managed utilizing asynchronous synchronization. The provisioning data can be stored in the databases separately from the session data.

Hybrid synchronization of telecommunication network databases

Systems, methods, and computer-readable media are described herein to which dynamically provide indications within a database that a monitored communication protocol is congested or otherwise unavailable. Key performance indicators are monitored on a first wireless communication protocol to determine if it is congested. Once the congestion is determined, the database is updated, and a terminating call application server may then receive an indication that the first wireless communication protocol is congested and may suggest to another communication protocol.

Selecting voice over new radio or evolved packet system fallback

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.
