Abstract: Methods and systems for MT (mobile terminated) call recovery in an IP multimedia system (IMS) network are discussed herein. A method according to an implementation comprises receiving, via a network, a request to establish a call session with a user equipment (UE); sending, to a first serving call session control function (S-CSCF), a first invite associated with the request; determining that no response is received from the first S-CSCF after a pre-set time period; sending, to a second S-CSCF, a second invite associated with the request, causing the second S-CSCF to perform actions including: obtaining an authentication to establish the call session; and sending, to a proxy call session control function (P-CSCF) of the UE, a third invite associated with the request; and receiving, via the network, a confirmation that the call session with the UE is established.

Abstract: A computer-implemented method for validating the origination of an incoming customer call on a wireless communication network may include receiving a SIP invite message at the wireless communication network when the call is initiated, determining whether the SIP invite message includes one or more indicators indicating that the call originated within the wireless communication network from a device with a SIM registered in the wireless communication network, and writing a classification code to a database indicating that the call is validated if the SIP invite message includes the one or more indicators. The method may further include receiving the call at an agent computer device with caller identification information, querying the database via the agent computer device according to the caller identification information to obtain the classification code of the customer call, and suppressing a step used for call authentication if the classification code indicates that the call is validated.

Abstract: A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing an aggregate frequency bandwidth of the first air-interface connection with an aggregate frequency bandwidth of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

Abstract: Emergency alert systems and methods for disabled and/or differently abled persons are disclosed. Upon receiving an alert message, the system translates the alert message to an audio message (text to speech) when the text to speech feature is enabled. In some implementations, the system waits fora threshold period of time (e.g., 30 seconds) to receive a user acknowledgment of the alert message, and translates the alert message to an audio message if no acknowledgment is received within this time. The user acknowledgment can be received via a selection of an option (e.g., by clicking an “OK” button) and/or via an audio option (e.g., by saying “Ok, received”) when the text to speech feature is enabled. The system then outputs (e.g., reads out loud) the translated message so that the disabled or differently abled persons can be informed of the emergency situation. After outputting the translated message, the system can further wait for a user acknowledgment of the translated audio message.

Abstract: Internet Protocol Multimedia Subsystem (IMS) restoration for a user equipment (UE) may be automatically triggered in response to the UE receiving a message waiting indicator (MWI) or a text message via a fallback protocol that is used as a backup for a primary protocol for delivering the MWI or the text message. For example, if a UE receives a MWI via Non-Access Stratum (NAS) protocol (where NAS protocol serves as a fallback protocol for Session Initiation Protocol (SIP) to deliver the MWI when IMS-based services are unavailable), an IMS restoration procedure may be triggered for the UE where the UE sends a request to register for one or more services of a telecommunication service provider in an effort to restore IMS-based services for the UE, thereby allowing calls to be subsequently established with the UE.

Abstract: System and methods for smart cell selection and reselection are described. A mobile device may attempt to camp on a cell in a tracking area that has advertised a particular frequency band. If the mobile device is unable to recognize an information element identifying a different subset of the advertised frequency band than that supported by the mobile device, the mobile device will store a record of the tracking area and the advertised frequency band and compare future cell information broadcasts to the entry, avoiding attempts to operate within cells in the same tracking area advertising the same frequency. In this way the mobile device conserves resources by avoiding actions in incompatible cells and avoids storing information about many cells by only storing the tracking area information.

Abstract: Described herein are techniques for enabling remote implementation and enforcement of usage settings on one or more user devices. In some embodiments, a wireless carrier network maintains information on relationships between various user devices. Each relationship may be active under specified conditions (e.g., time and/or location) and is associated with usage settings that dictate one or more rules to be enforced while the relationship is active. In some embodiments, a set of usage settings may be generated for a particular user device based on all active relationships associated with that user device. The set of usage settings may be enforced by a mobile application installed upon a user device or by a wireless carrier network that blocks certain network traffic to and/or from the user device.

Abstract: The disclosed technology provides systems and methods for dynamically locking and unlocking wireless communication devices by enforcing updateable subscriber identity module (SIM) and public land mobile network (PLMN) policy information. A device receives policy information from a policy server, compares the policy information against information in the SIM and dynamically updates a lock state of the device based on the policy information, potentially overriding a factory lock state of the device. The policy information can include a whitelist indicating the SIMs that the device can accept. The device can also obtain and apply branding information when the SIM information matches the received policy information, and block access to certain device functionality when the SIM information does not match the policy information.

Abstract: Methods and systems for reporting zero usage for immediate trigger types are discussed herein. According to an implementation a communication session is established between a user equipment (UE) and the 5G network to provide service/content requested by the UE. A session management function (SMF) may receives a message from the UE to report the usage of one or more data units granted to the UE. The message indicates that an event occurs during a zero-usage time period. The SMF determines whether the event triggers a charging condition. When the event triggers a charging condition that needs to be reported immediately, the SMF sends a charging data request to a charging function (CHF) to report the event, regardless the one or more data units have zero-usage.

Abstract: Systems and methods for detecting application behavior using network traffic are described herein. The systems and methods enable a network to utilize network traffic data to determine various metrics and behavioral patterns associated with applications and their use. The patterns can be used to monitor traffic from a specific user device and across the network. Further, the information may be used to generate a trust score that provides a network and/or a user with information relating to an application.

Abstract: Systems and methods for registering and selecting a Proxy-Call Session Control Function (P-CSCF) are described herein. The systems and methods described herein use a Network Repository Function (NRF) to receive status updates of P-CSCFs available to be selected. The status updates include information such as, but not limited to, whether or not the P-CSCF is active or above or below a predetermined loading threshold. The NRF provides the information to a Session Management Function (SMF) that selects which P-CSCF is to be utilized for a Session Initiation Protocol. The SMF can also use loading levels of the P-CSCFs to perform load balancing.

Abstract: Systems and methods present practical applications to directing emergency alerts from cellular-based message distribution systems to distributed desktop applications via a desktop application gateway. Logic in the desktop applications and their corresponding IP network gateways for the desktop application may direct alerts from the cellular-based system to distributed desktop applications having a connection to the gateway. A distributed application may determine a location of the user and include enhancements to display the alert at a user's computing device. The gateway for the distributed application may store the location information for each logged-in user or registered instance of the user. An interface between the cell broadcast center and the distributed application gateway may allow the gateway to receive the alert, including a region for distributing the alert, from the cell broadcast center, and send the alert to all registered users with a location matching the alert region.

Abstract: This disclosure describes techniques for creating a hybrid mesh of unlicensed wireless frequency bands between two or more vehicles communicating using an unlicensed wireless frequency band, and a massive MIMO base station communicating with the two or more vehicles using a licensed wireless frequency band. The hybrid mesh can be used to upload and download data from a vehicle in motion. The hybrid mesh can be formed via V2V connections between the vehicle and nearby vehicles. In other words, if a vehicle moves into a region outside the operating boundary of a 5G-NR massive MIMO base-station node, the vehicle can interact with other vehicles to generate a data pipeline using the unlicensed wireless frequency band from the vehicle the nearby vehicle, and using the licensed wireless frequency band from the nearby vehicle to the nearest, massive MIMO base station.

Abstract: A method performed by a platform for real-time intake capacity assessment of a project includes routing, to a service desk, a request to assess capacity for the project. In response, an electronic message is communicated with a link to a form to retrieve structured information about the project. An assessment template is populated with structured information that includes feature-level information of the project (e.g., a level-of-effort (LOE) for developing a software product). The platform can dynamically estimate a capacity measure for the project, which is then used to generate a visualization on a dashboard based on the estimate of the capacity measure. As such, the platform enables better decision-making, planning, and prioritization.

Abstract: A computer-implemented method for managing radio spectrum in a cellular network including periodically analyzing a local spectrum utilization data to determine spectrum use levels at the local base station. The method may include periodically receiving, at the local base station, neighbor spectrum utilization data from at least one neighbor base station in the cellular network. The neighbor spectrum utilization data is associated with spectrum use levels at the at least one neighbor base station. The method may include receiving a spectrum assignment request from a mobile computing device and, in response, determining a spectrum assignment for the mobile computing device based on at least one of the neighbor spectrum utilization data and local spectrum utilization data. The method may include transmitting the spectrum assignment to the mobile computing device.

Abstract: Systems and methods of a predictive handoff that cause a handoff of user equipment from one network site to another network site. A network site connected to the user equipment monitors a quality of a signal between the network site and the user equipment and receives movement information from the user equipment. The network site selects a potential network site for the handoff of the user equipment based on the movement information and a potential signal quality between the user equipment and the potential network site. The network site coordinates the handoff and causes the selected potential network site to transmit a handoff instruction to the user equipment. The network site also instructs the user equipment to listen for the handoff instruction and the user equipment and potential network site can complete the handoff.

Abstract: A token-based security risk assessment service for multi-factor authentication (MFA) is described. An enterprise may utilize the security risk assessment service, and a telecommunication service provider may provide the security risk assessment service as a network-based service. The security risk assessment service may be configured to monitor identifiers (IDs) of elements associated with users associated with an enterprise to determine if any have changed. Any changes may be factored into an adjustment to the user's security profile. Furthermore, the enterprise can utilize the security risk assessment service to implement a token-based MFA scheme where Short Message Service (SMS) is used as an authentication factor.

Abstract: The disclosed system adjusts performance of a network. The system obtains a configuration and historical performance of the network. Based on the historical performance, the system identifies a time window and a location associated with the network. Based on the configuration and the historical performance, the system identifies a parameter associated with the network, parameter adjustment, success criterion, failure criterion, and deployment duration. Based on the time window, the location, and the deployment duration, the system determines a testing time window within the time window, where the testing time window satisfies a density threshold indicating low impact to UEs associated with the network. The system deploys the parameter adjustment at the location during the testing time window, and monitors the performance of the network. The system determines whether the success or failure criterion is satisfied, and preserves the parameter adjustment or terminates the test, respectively.

Abstract: Techniques remotely managing an embedded Subscriber Identity Module (eSIM) by a telecommunication network provider are described herein. The telecommunication network provider can implement an eSIM enterprise system to manage provisioning, activating, security, and testing of the eSIM. The eSIM enterprise system can activate the eSIM, update a user profile associated with the eSIM, determine a capability of the eSIM, test functionality of the eSIM, process a payment to modify the eSIM, secure communications associated with the eSIM, and determine interfaces for communicating with a variety of devices, applications, or business entities associated with the eSIM.

Abstract: The identification of a user device as an unmanned aerial vehicle (UAV) may cause the wireless communication network to implement certain operations. A determination may be made based on one or more behavior characteristics of a user device as to whether the user device is an unmanned aerial vehicle (UAV) instead of an airborne user device carried in a manned aircraft as the user device communicates with a wireless communication network via one or more base stations. In response to determining that the user device is the UAV instead of the airborne user device carried in the manned aircraft, a base station handover threshold for the UAV may be modified to prolong a communication duration of the UAV with a base station when a decrease in signal strength or an increase in signal interference of a signal provided by the base station occurs.
