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

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.

Delivery of geographic location for user equipment (UE) in a wireless communication network

A data communication system authenticates a wireless communication device, and in response, determines status information for the wireless communication device. The data communication system receives a telephony request for the wireless communication device. The data communication system delivers a telephony service to the wireless communication device in response to the telephony request and based on the status information.

User equipment (UE) status information delivery in a wireless communication network

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 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 provides a text-messaging service and a voice-calling service to wireless communication devices. The wireless communication network monitors performance of text-messaging functions and voice-calling functions. The wireless communication network prioritizes the text-messaging functions and the voice-calling functions based on their performance. The wireless communication network transfers function lists that prioritize the text-messaging functions and the voice-calling functions by their performance. The wireless communication network wirelessly exchanges text-messaging signaling and voice-calling signaling between the wireless communication devices and the text-messaging functions and the voice-calling functions. Individual ones of the wireless communication devices exchange the text-messaging signaling with selected ones of the text-messaging functions based on the function list that prioritizes the text-messaging functions by their performance. Individual ones of the wireless communication devices exchange the voice-calling signaling with selected ones of the voice-calling functions based on the function list that prioritizes the voice-calling functions by their performance.

Media content service delivery in a wireless communication network

A wireless communication device wirelessly downloads a user application, and in response, wirelessly receives signaling that indicates a wireless network slice for the user application. The wireless communication device wirelessly downloads another user application, and in response, wirelessly receives other signaling that indicates another wireless network slice for the other user application. The wireless communication device executes the user application, and in response, wirelessly transfers a request for the wireless network slice and wirelessly exchanges application data for the user application over the wireless network slice for the user application. The wireless communication device executes the other user application, and in response, wirelessly transfers another request for the other wireless network slice and wirelessly exchanges other application data for the other user application over the other wireless network slice for the other user application.

Wireless network slice optimization for user applications

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.
