Abstract: A wireless communication network delivers status information for User Equipment (UE) upon request. A network controller exchanges registration signaling with the UE and exchanges authentication signaling for the UE with a Unified Data Management (UDM). The UDM exchanges the authentication signaling with the network controller and responsively transfers a UDM request for the UE status information to the network controller. The network controller determines the UE status information and transfers the UE status information to the UDM in response to the UDM request. The UDM receive the UE status information from the network controller and transfers the UE status information to a Unified Data Repository (UDR). The UDR receives the UE status information from the UDM and receives a status request for the UE from a network element. The UDR responsively transfers the UE status information for the UE to the network element.

Abstract: A wireless communication network deregisters network functions. In the wireless communication, a network data system receives a deregistration command that indicates a wireless User Equipment (UE) and forwards the deregistration command to a Unified Data Management (UDM). The UDM receives the indication and determines a Data Network Name (DNN) for the wireless UE. The UDM identifies a network controller and a session controller for the wireless UE based on the DNN. The UDM transfers deregistration notifications to the network controller and session controller. The UDM receives a deregistration acknowledgement from the network controller. The UDM directs the network data system to remove stored session data for the session controller. The network data system receives the direction from the UDM and responsively removes stored session data for the session controller.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A carrier network may detect and prevent completion of SIM swap frauds. For example, a carrier network may, based at least in part on a SIM swap request to replace a first SIM associated with a subscriber with a second SIM, store first information associated with the first SIM. Subsequent to the execution of a SIM swap to replace the first SIM with the second SIM, the carrier network may perform fraud detection on the SIM swap based at least in part on the first information associated with the first SIM stored based at least in part on the SIM swap request and based at least in part on second information associated with the second SIM and based at least in part on the SIM swap being detected as fraudulent by the fraud detection, cause the second SIM to be prohibited from operating with respect to the subscriber.

Abstract: 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.

Abstract: A wireless communication system comprises Public Land Mobile Networks (PLMNs) that use Uniform Data Repositories (UDRs) to serve wireless User Equipment (UEs) over wireless network slices. A serving PLMN determines a UE Identifier (ID) for a wireless UE and a slice ID for a wireless network slice. The serving PLMN indicates the UE ID and the slice ID to a Service Communication Proxy (SCP) in the serving PLMN. The SCP selects a UDR in a different PLMN based on the UE ID and the slice ID. The SCP indicates the UE ID and the slice ID to the selected UDR in the different PLMN. The selected UDR in the different PLMN transfers UE information for the UE for delivery to the network element in the serving PLMN. The network element in the serving PLMN controls the wireless network slice for the wireless UE based on the UE information.

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.

Abstract: Methods and systems for reporting a provisioning transaction in a wireless communication network are disclosed. According to an implementation, a lawful interception management system (LIMS) of the wireless communication network may receive, from a law enforcement agency (LEA), a request to track activities of a subscriber of services provided through the communication network. The request may be submitted through a third-party server located in a public network. LIMS may transmit the request to a communication service provider (CSP). Upon receiving the request, CSP may forward the request to one or more servers via dedicated interfaces respectively assigned. The one or more servers may be configured to intercept the provisioning transactions that occurred on different radio access networks, e.g., 2G/3G, 4G/LTE, or 5G. Once the provisioning transaction is intercepted, LIMS may be immediately notified via the dedicated interfaces. Information related to the provisioning transactions is reported to LEA.

Abstract: A wireless communication network transfers a data message to a User Equipment (UE). A wireless network control system registers the UE, and in response, transfers a UE registration notice for the UE and the wireless network control system to a wireless network database system. The wireless network database system receives the UE registration notice, and in response, transfers the UE registration notice to a message center. The message center receives the UE registration notice. The message center receives the data message for the UE, and in response, transfers the data message to the wireless network control system based on the UE registration notice. The wireless network control system receives the data message, and in response, transfers the data message to the UE.

Abstract: Systems and methods are provided for managing updates to user devices, and in particular, SIM-based OTA updates. In some cases, SIMOTA updates need to be made while a user device has a cellular connection (e.g., 4G/LTE, 5G). As such, an instruction is transmitted to the user devices that need a SIM-based update but that currently have a non-cellular connection. The instruction is for the user devices to deregister from the non-cellular connection and to reregister using a cellular connection. An indication is received that at least a portion of those user devices now currently have a cellular connection. The SIM-based updates are then transmitted to those user devices.

Abstract: Described herein are techniques, devices, and systems for performing hybrid synchronization of databases in a telecommunication network. 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.

Abstract: A wireless communication network serves a User Equipment (UE) with a Network Exposure Function (NEF) and multiple Unified Data Elements (UDEs) like Unified Data Managements (UDMs) and Unified Data Repositories (UDRs) The NEF receives initial network data and transfers a UDE query to a Network Repository Function (NRF). The NRF selects a Unified Data Proxy (UDP) and indicates the UDP to the NEF. The NEF receives the UDP indication and responsively transfers the initial network data to the UDP. The UDP receives the initial network data, and in response, selects one of the UDEs. The UDP transfers the initial network data to the selected one of the UDEs. The selected one of the UDEs receives the initial network data, and in response, generates and transfers new network data. In some examples, the UDEs comprise UDMs/UDRs that reside in different Public Land Mobile Networks (PLMNs) from one another and from the NEF.

Abstract: A wireless communication network serves a wireless User Equipment (UE). The wireless UE exchanges user data over a data session of a Dynamic Network Name (DNN) while exchanging other user data over other data sessions of other DNNs. An Access and Mobility Management Function (AMF) receives a DNN message for the wireless UE and the DNN and responsively transfers a reattach message for the data session of the DNN to the wireless UE. The wireless UE receives the reattach message and responsively terminates the data session of the DNN and transfers a session message for the DNN to the AMF. The AMF receives the session message for the DNN and the wireless UE and responsively establishes a new data session for the DNN. The wireless UE exchanges new user data over the new data session of the DNN while exchanging additional user data over the other data sessions of the other DNNs.
