Abstract: A listening device for tracking locations of a tracking device in a physical space includes one or more wireless transceivers, one or more sensors, and one or more processors. The processors generate positional indicators associated with the listening device based on signals generated by the one or more sensors, based on communications with an external device, or both. The listening device communicates with the tracking device to receive a tracking signal, based on which the processors identify a position of the tracking device relative to the listening device. The tracking device is located within the physical space based on the identified position of the tracking device relative to the listening device and the positional indicators associated with the listening device.

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: The disclosed technology provides a system and method for determining an uplink (UL) waveform for a mobile device to use for UL transmission in carrier aggregation or dual connectivity modes, where the UL waveform is selected to eliminate or minimize the deleterious effects of intermodulation distortion (IMD). The system identifies frequency bands scheduled for use by the mobile device for concurrent UL transmissions and for DL transmissions and determines if the combination of frequency bands can lead to high IMD. If the combination can lead to high IMD, the system can instruct the mobile device to switch to a Discrete Fourier Transform (DFT)-spread Orthogonal Frequency Division Multiplexing (OFDM) (DFT-s-OFDM) waveform for UL transmissions; if the combination would not likely lead to high IMD, the system can instruct the mobile device to switch to a Cyclic Prefix OFDM (CP-OFDM) waveform for the UL transmissions.

Abstract: A mobile device, via a roaming platform, can switch IMSIs (e.g., Home IMSI-1, Roamer IMSI-2, etc.) depending on a location of the mobile device. Upon switching IMSIs, the roaming platform can forward the update location to an HLR of the home network and roaming network. If the MMSC on the home network receives an MMS message, the MMSC on the home network may query the HLR for a current location. From the query, if the message recipient is roaming, the MMSC on the home network may communicate with the MMSC on the roaming network to deliver the message. As a result, the roaming network can handle the routing of the message without a data session routed back through the home network.

Abstract: A touchless multi-staged retail process automation systems and methods (retail process automation system) to automate key store functionalities within retail stores is disclosed. The retail process automation system receives a set of commands (e.g., a voice command) to automatically perform retail store operations such as opening a store, closing a close, automatically opening tills, etc. with the single command. As a result, the retail process automation system replaces the multiple-touches required by conventional systems with a touchless solution, thereby providing increased time and resource efficiency of managing store operations. For example, the retail process automation system intercepts a voice command to identify the associated retail store information and source of the command. The retail process automation system then generates a set of operations associated with the received voice command to alter a state of the retail store.

Abstract: The system receives, from a telecommunications network subscribed to by the wireless device, a list of roaming networks. The system connects to a roaming network from the list of roaming networks. The system enters a roaming mode from a standard mode. The roaming mode reduces the amount of data used by the wireless device by preventing the wireless device from performing background tasks. Background tasks include processes performed by the wireless device to keep an application on the wireless device up to date. The standard mode causes the wireless device to operate at a higher data level and a less optimized battery level compared to the roaming mode. The system connects to the telecommunications network. The wireless device disconnects from the roaming network before connecting to the telecommunications network subscribed to by the wireless device. The system enters the standard mode.

Abstract: The system receives a SIP call from a UE associated with a user, where the SIP call includes multiple fields, and where a field among the multiple fields indicates that the SIP call is the open-line call. The system receives a first indication that the UE associated with a callee has generated a notification to the callee of the SIP call. Upon identifying the SIP call as the open-line call and receiving the first indication, the system sends a first message to the UE associated with the caller that the UE associated with the callee has generated the notification. The first message indicates to the UE associated with the caller to generate a first inaudible notification indicating that the UE associated with the callee generated the notification.
