Abstract: Methods for resource and slice allocation for multi-mode operation in Open RAN architectures are described. A programmable radio exposure function switches between real-time and near-real-time modes of operation for a radio access network (RAN) intelligent controller of a telecommunications system. An application programming interface is exposed by the radio exposure function and performs radio resource management for the telecommunications system. The application programming interface communicates with services and/or applications to control RAN functions, and allocates RAN resources of the telecommunications system to a user equipment for the services and/or applications. A machine learning module is embedded within the radio exposure function and trained to identify network slices of the telecommunications system for the services and/or applications.

Abstract: A method performed by a security system of a 5G network to protect against cyberattacks on a personalized basis. The security system can identify a cybersecurity threat to a wireless device based on contextual information relating to the wireless device, a user preference, or a call detail record. The security system can determine a one-time fee to charge the user in exchange for protecting the wireless device against the cybersecurity threat, generate an coupon to protect the wireless device against the cybersecurity threat, and send the coupon to the wireless device based at least in part on the contextual information relating to the wireless device and the user preference. When the security system receives an indication that the coupon was redeemed, responds by deploying a network asset to protect the wireless device against the cybersecurity threat.

Abstract: Systems, methods, and devices to reduce the channel estimation overhead by collecting data from many UEs and building a location-based mathematical model are disclosed. During building of the model, a reference signal is used to collect location- and signal-related data from connected UEs. Once the model is successfully built, it is then transmitted and/or downloaded to each new UE that connects to the base station. The UEs and/or the base stations then use this model to determine their own transmission parameter values. The UEs also report their location to the base stations, which use the model to estimate channel conditions and adapt transmission parameters for themselves.

Abstract: A method performed by a network node that generates a schedule of communication exchanges between the network node and a small cell of a telecommunications network. The schedule is unique for the small cell among multiple small cells and sets times for sending status signals to the small cell and receiving counterpart response signals from the small cell. When the network node detects non-compliance with the schedule, the network node can begin to monitor the small cell for anomalous activity. Upon detecting that the anomalous activity includes malicious activity, the network node can communicate with the small cell wirelessly to deauthorize the small cell.

Abstract: A computer system obtains information describing a geographical area segmented into multiple first clusters serviced by a telecommunications network. Multiple test locations are identified within the first clusters. Each test location is located within a grid of the geographical area. Each first cluster is recursively segmented into multiple second clusters until a difference between a number of test locations within each second cluster and a target number of test locations is less than a threshold number of test locations. A route is generated connecting test locations within each second cluster, using a routing application programming interface for performing drive testing of the telecommunications network. The computer system sends the route to one or more computer devices for performing the drive testing at the test locations in a sequence corresponding to the route.

Abstract: A method performed by a cybersecurity system that receives a registration request of a wireless device over a 5G network and, in response, selects a network slice associated with a capability, a traffic characteristic, and includes network resources. The system dynamically provisions security resources for multiple network slices based on respective security requirements, which are determined by monitoring network traffic associated with functions or applications supported by the network slices. The system allocates the selected network slice including security resources that satisfy its security requirement to support the wireless device.

Abstract: The disclosed technology includes at least one method performed by a system to dynamically adapt a computer desktop of a customer service agent to a live audio dialogue. The system can cause a speech feature analyzer to process a segment of the live audio dialogue to output multiple speech features and obtain search results by querying a database for the multiple speech features. The method can further include generating control signals based on the search results and cause an API to configure the computer desktop based on the control signals. The system can dynamically adapt the computer desktop in accordance with additional control signals that are generated based on next segments of the live audio dialogue.

Abstract: Techniques for determining a location of a roaming device on a host telecommunications network are described herein. The host telecommunications network can implement a location server to determine a geographical location of a user equipment (UE) that generates an emergency message to an emergency service center. The location server can exchange data representing device information, network information, or user information with a subscriber server of a home telecommunications network, and use the data to initiate determination of the geographical location. The location server can initiate, establish, maintain, or otherwise determine a geographical location of the UE for sending to the emergency service center (e.g., to enable the UE to exchange text communications with a Public Service Answering Point).

Abstract: Techniques for measuring and reducing signal misalignment in a dual connectivity environment are discussed herein. When using Non-Standalone Architecture (NSA), a device initially communicates with a network using a Long-Term Evolution (LTE) connection. After the LTE connection is established, an LTE base station may instruct the device to measure signal strength of a neighboring New Radio (NR) cell during a specified LTE measurement gap. When the NR cell is implemented by an indoor NR base station, the NR signal may not be sufficiently synchronized with the LTE signal and the device may be unable to measure the NR signal during the measurement gap. In these cases, the device can determine the frame timing difference between the LTE and NR signals, obtain an adjusted measurement gap that reduces any measurement gap misalignment, and attempt to measure the signal strength of the NR cell using the adjusted measurement gap.

Abstract: System and methods for generating deployments, such as software architectures, and identifying standards-related requirements applicable to deployments. A plain language message is received that describes a desired deployment. One or more entities are extracted from the plain language message. Based on the extracted entities, the system recommends one or more standards-related requirements relevant to the desired deployment, such as requirements for legal, privacy, and/or security standards. A selection is received from among the recommended standards-related requirements, the selected standards-related requirements being associated with a set of telecommunication resources configured to fulfill the standards-related requirements. The set of telecommunication resources can comprise microservices, data sources, and/or communication channels. The desired deployment is generated, which includes the set of telecommunication resources configured to fulfill the standards-related requirements.

Abstract: A system and methods for provisioning and managing databases are disclosed. A request is received to provision a database for a software application, including a general database type and one or more parameters for the requested database. Based on the received request, the system generates database recommendations including a recommended specific type of database. The system receives a selection of one of the recommended databases and determines whether a user submitting the request is approved, based on a level of privileges or a quota. When the user is approved for the selected database, the system generates the selected databased by retrieving database code from a repository. The system updates an inventory to reflect the provisioning of the generated database. The generated database can then be managed using the system, including predicting adverse events associated with the generated database and/or predicting a need to adjust resources for the generated database.

Abstract: Systems and methods for telecommunications network coverage optimization are disclosed. The network coverage optimization system computes a usability index value for a geographic area using measured values of telecommunications network usability indicators. The telecommunications network usability indicators are related to network coverage (e.g., whether the user has enough bars and can make a call), quality of service (e.g., whether the speech and data quality are good), and data speed (e.g., the amount of buffering the user is experiencing). The telecommunications network usability indicators can be selected based on an importance rating associated with them. Then, for each geographic area, the network coverage optimization system computes a score value and a weight value for each selected telecommunications network usability indicator. Using the computed score values and the computed weight values, the network coverage optimization system computes a usability index value for the geographic area.

Abstract: The disclosed system provides a facility for improving user call quality at a mobile device. The system includes an over-the-top (OTT) client that may be installed on the mobile device for allowing a user to initiate call quality tests. The system performs a call quality test to generate a call quality score or metric from the obtained audio sample via a Call Quality Algorithm. If the call quality score or metric falls below a predetermined threshold, the system may suggest (via the OTT client or via a push notification) that the user of the mobile device switch from the first communication interface (e.g., a radio network such as 4G) to a second communication interface (e.g., Wi-Fi) on the mobile device. The disclosed system tracks the call quality score or metric of multiple mobile devices operating within a telecommunications network, identifies service outages within the network, and notifies impacted mobile devices.

Abstract: The disclosed system provides a facility for split billing for a single user on multiple billing systems. The disclosed system activates the user on each respective billing system using a unique pairing, such as an international mobile subscriber identity that identifies the user, and a mobile station international subscriber directory number that identifies a particular user device. As device data is routed through a telecommunication network via each access point name (APN), the network generates call detail records (CDRs), which include an indication of the APN used. The CDRs are routed to a mediation platform that uses the received APN information to route each CDR to the appropriate target billing system and to the appropriate service types.

Abstract: Systems and methods for aerial unmanned vehicle (for example, drone) early warning privacy breach detection, interception, and defense are disclosed. The system detects drones within a threshold distance of an individual or configurable location, notifies the individual of the drones' existence, tracks the drones, and executes countermeasures. The system can communicate with telecommunication networks or other sources (for example, FAA) to identify and filter out drones that are authorized to be in the airspace around the individual.

Abstract: To detect “silent” crashes of communications processors in a mobile device, the mobile device analyzes signal strength icon images using a trained image processing model. During operation of a mobile device, the device captures images of a signal strength icon that is displayed by the device and that visually represents a telecommunications signal strength detected by the mobile device. The mobile device applies the captured images to the trained image processing model, which is configured to output a prediction of whether the communications processor in the mobile device crashed.

Abstract: The disclosure herein describes a data processing system that enhances its performance based on context of the data to be processed. An input data set is obtained, and a context of the data set is identified based on context metadata. Anomalous data of the data set is identified, and a correction model is applied to the anomalous data to generate corrected data based on the identified context. The data of the input data set, including the corrected data, is extracted to a landing data store. A transformation process of the extracted data is optimized based on the identified context and the optimized transformation process is performed on the extracted data to generate transformed data. The transformed data is loaded into a target data store. The described system is configured to handle anomalous data and optimize transformation processes automatically, which enhances the efficiency and flexibility of the system.

The method also includes transmitting, by the user device, a Session Initiation Protocol (SIP) message to an SIP server indicating a termination of a communication session. The SIP message includes the one or more indicators to enable to SIP server to determine a cause for the termination of the communication session.

Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.
