Abstract: Embodiments described herein relate to managing access to an embedded universal integrated circuit card (eUICC) to obtain subscriber identity module (SIM) information without requiring cellular baseband wireless processing support. A baseband component of a wireless device that connects to the eUICC via a first interface can be in a reduced power state, and under certain conditions a processor external to the eUICC can access the eUICC via a second interface without booting up the baseband component to a normal (full) power state. When access to the eUICC via the first interface through the baseband component is required, the baseband component can be booted to a normal (full) power state to communicate with the eUICC. Additionally, a wireless device in which the baseband component is in a reduced power state or is absent can access one or more services of a mobile network operator (MNO) via a non-cellular wireless interface.

Abstract: This application describes managing configuration of a bootstrap electronic SIM (eSIM) for a wireless device. A bootstrap eSIM on an embedded universal integrated circuit card (eUICC) of the wireless device is configured as needed to provide cellular wireless access. The bootstrap eSIM is configured with an initial international mobile subscriber identity (i-IMSI) value used to establish a cellular connection to obtain a bootstrap IMSI (b-IMSI) value allocated for temporary, dedicated use by the wireless device. The b-IMSI value is selected by a bootstrap server based on a bootstrap selection rule obtained from a bootstrap rules service, where the bootstrap selection rule accounts for a use case type provided by the wireless device and indicating a purpose for use of the b-IMSI value. The b-IMSI value is returned to a pool for use by other wireless devices after expiration of a timer or responsive to a delete notification message.

Abstract: Methods and apparatuses for self-generation of a full function electronic subscriber identity module (eSIM) profile for a wireless device by merging dynamically-provisioned credentials into an eSIM template that is specific or agnostic to a mobile network operator (MNO). When an MNO-specific eSIM template is available in the wireless device, the MNO-specific eSIM template is selected and provided to an embedded universal integrated circuit card (eUICC) of the wireless device. Alternatively, when the MNO-specific eSIM template is not available in the wireless device, an MNO-agnostic eSIM template is selected and provided to the eUICC. The dynamically-provisioned credentials are merged with the selected eSIM template to cause the eUICC to create a full function eSIM profile for the wireless device.

Abstract: Distributed real-time rendering is a cutting-edge solution to address the ever-increasing demands for realistic and immersive visual experiences, such as provided by augmented or artificial reality applications. Embodiments of the present specification provide a method and a system for distributed real-time rendering of a scene. The rendering is distributed among a root instance and a plurality of node instances. The root instance receives the scene to render, segments it into a plurality of objects, computes lighting parameters, assigns rendering tasks associated with objects to node instances, and communicates object metadata and the lighting parameters to the assigned node instance. The node instances render objects and create point clouds and u, v maps, which are then used by the root instance to render the scene for real-time display. The method and system can be used by end devices that include position sensors, processors, communication means and a display to provide immersive experiences.
