The technology described herein improves management of core network connectivity in order to limit network connectivity issues from spreading to other areas in the wireless network. A determination that a predetermined threshold of service requests and/or service request failures associated with one or more core network entities in a first geographic area has been exceeded during a first time period serves as the basis for preventing the one or more core network entities from receiving services from a backup UDR during a second period of time, the second time period subsequent to the first time period.

Management of core network connectivity to a unified data repository in a wireless communications network

The technology relates to secure management of notifications on mobile devices. The method involves receiving messages over a telecommunications network. In instances where the mobile device is in an unlocked state, the user interface of the mobile device displays the message content through notifications on the user interface. The process includes determining the unlocked state of the mobile device and assessing whether the message contains sensitive content. Upon such determination, the mobile device performs a security process, which includes preventing showing the sensitive content in the notification until the user is authenticated. Upon successful authentication, the mobile device presents the content of the notification on the user interface.

Multi-layered authentication notification system for mobile devices

Described herein is a node of a telecommunications network configured to determine that a primary index for data repositories of the telecommunications network is operating in a fail-open mode and, in response, provide a request received by the node to substantially all data repositories referred to by the primary index. The node is further configured to receive a response from one of the data repositories and, based at least in part on the response, build a secondary index mapping data repositories to subscriber identifiers. When a further request is received by the node in fail-open mode, the node may refer to the secondary index first and, if the subscriber identifier from the further request is not present in the secondary index, provide the further request to substantially all data repositories referred to by the primary index.

Fail-open operation for data repository indices

Systems and methods are provided for causing a prospective provisioning, in near real-time, of various wireless communication protocol databases based on subscribers meeting particular criteria for respective wireless communication protocols. In operation, some aspects are directed to receiving an indication that a first provisioning client associated with a first subscriber has provisioned a first database to access a first service. In response to the receiving, these aspects include automatically read at least a second database to determine whether the second database has already been provisioned to access the first service. At least partially in response to determining that the second database has not already been provisioned to access the first service, these aspects automatically transmit a request to provision the second database such that at least the first subscriber can access the first service using a second wireless communication protocol and a first wireless communication protocol.

Near real-time network service deployment across different wireless communication protocols

Embodiments of the present disclosure are directed to systems and methods for managing attachment requests for UEs in a wireless network environment comprising a first set of base stations and a second set of base stations when the first and second set of base stations have at least one unique network characteristic. By rejecting attachment requests to UEs attempting to access one or more base stations of the second set of base stations, the conventional cell selection and attachment process will drive UEs to attach to the first set of base stations.

Managing access requests in a redundant network environment

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

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

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.

Messaging in a wireless communication network

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.

SIM swap fraud prevention

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.

Systems and methods are provided for consistent policy enforcement across networks. A subscription is provisioned at a first network with an initial service policy. The first network queries a second network for updated service policy information. In response to the query, updated service policy information for the subscription is received. The updated service policy information is determined by the second network based on a selection criteria attribute for the subscription satisfying selection criteria. The selection criteria attribute is unavailable at the first network. Service is provided to a device associated with the subscription in accordance with the updated service policy information.

Consistent policy enforcement across networks

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.

Wireless communication service over a network exposure function and multiple unified data elements

A wireless communication system serves wireless user devices based on wireless user device Identifiers (IDs). The wireless communication system detects a loss of synchronization between data repositories, and in response, identifies the wireless user device IDs that were allocated to the data repositories during the loss of synchronization. The wireless communication system reallocates the identified wireless user device IDs to the data repositories. The wireless communication system synchronizes the reallocated wireless user device IDs across the data repositories. The wireless communication system serves wireless data communications to the wireless user devices based on the reallocated and synchronized wireless user device IDs.

User equipment (UE) identification in a wireless communication network

Network circuitry authorizes User Equipment (UEs) for wireless services from wireless networks. The network circuitry stores lists of network identifiers that are associated with UE types. The network circuitry receives an authorization request that indicates a network identifier and a UE type. The UE type comprises model, operating system, user application, and/or radio frequency. The network circuitry retrieves a networks list for the UE type and compares the network identifier from the authorization request to the network identifiers on the network list. The authorization circuitry authorizes the UE responsive to a match between the network identifier from the authorization request and a network identifier on the network list.
