Abstract: A unified device design is described. In an example, a user device can be designed to be permissibly operable with at least two different service providers such that the user device is associated with static features that are applicable for each of the at least two different service providers and the dynamic features that are applicable for individual ones of the at least two different service providers. In an example, a user device can be associated with a subscriber identity module (SIM) that is associated with a service provider. Based at least in part on using a permission to determine that the service provider is one of the at least two different service providers, a subset of dynamic features that are associated with the service provider can be accessed for configuring the user device with the subset of the dynamic features corresponding to the service provider.

Abstract: Registration of a user equipment (UE) with a circuit-switched (CS) network can be controlled in an “on-demand” fashion by waiting for a trigger event before registering the UE with an available CS network. In some embodiments, CS registration of a UE may be triggered when the mobility management entity (MME) node receives, from the UE, a service request that was sent using Non-Access Stratum (NAS) protocol, such as an extended service request (ESR) or a short message service (SMS) over NAS request. In some embodiments, CS registration of a first UE may be triggered when the MME node receives, from a home subscriber server (HSS), a notification of an incoming session request originating from a second UE to establish a communication session over a CS network with the first UE.

Abstract: Systems and methods of providing enriched call elements within outbound voice or video calls using rich communication services (RCS) are disclosed. The techniques include initiating a voice or video call from a first RCS-compatible device to a second RCS-compatible device, automatically sending an RCS invite or instant message including enriched call elements added from a business data server or from the first RCS-compatible device to the second RCS-compatible device, and presenting an indication of the enriched call elements to a user of the second RCS-compatible device concurrent with or prior to answering the voice or video call. Such enriched call elements may include location data, call priority data, call subject matter data, electronic images, or video clips.

Abstract: A standalone mobile device that is not configured to handle voice over 5G is configured to automatically disable its 5G NR radio such that the NR radio is inoperable with respect to 5G networks, e.g., the mobile device cannot connect to a NR base station. The disabling of the mobile device's ability to connect to a 5G network may be event triggered, where an example of the event may be that the mobile device is handling a VoWiFi call. When the mobile device is handling a VoWiFi call and the VoWiFi call needs to be handed over to a cellular network, then the mobile device may perform the handover procedure of the VoWiFi call to an LTE network rather than first attempting to hand the VoWiFi call over to a 5G network via an EPS-FB procedure. When the call ends, the mobile device may re-enable its NR radio.

Abstract: Arrangements and techniques for testing mobile devices within a test module. The test modules are portable and may be stacked to provide a modular testing system. A pulley system may be used to move an actuator arm horizontally in the X and Y directions. The actuator arm may be moved vertically in the Z direction such that a tip may engage a touchscreen of a mobile device being tested or a user interface element of the mobile device.
