Abstract: Apparatuses and methods for a wireless communication device having multiple Subscriber Identity Modules (SIMs) in which a first SIM is associated with an Internet Protocol (IP) Multimedia Subsystem (IMS) subscription used for IMS services. The method includes but not limited to, attaching the IMS subscription to a first cell of a packet-switched cellular network, determining a cause of IMS voice service being not currently available at the IMS subscription, determining availability of a wireless local area network (WLAN) connection at the IMS subscription, and providing voice service at the IMS subscription based on the cause of IMS voice service being not currently available and the availability of the WLAN connection at the IMS subscription.

Abstract: A method includes maintaining a notification system of a mobile device. The notification system is configured to receive a plurality of notifications generated by a plurality of applications of the mobile device. The notifications are displayed via a notification system user interface that is configured to provide a remind option for each notification. A first user input is received indicating that a user has selected the remind option for a notification, where in response thereto a device selection option is provided that displays information identifying one or more other devices on which to provide a reminder for the notification. A second user input is then received indicating that the user has selected at least one of the one or more other devices, where the mobile device then communicates with the at least one other device to configure the at least one other device to provide the reminder for the notification.

Abstract: In currently available user equipment (UE), the significantly more number of pixels in the 4K ultra high definition (UHD) display mode demands more processing power and consumes more battery charge than the 1080p high definition (HD) display mode or the standard resolution display mode. However, in low brightness, there is no perceived difference in display image quality among very high resolution (e.g., UHD), high resolution (e.g., HD) or standard resolution display modes, when viewed by the naked human eye. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for reducing battery drain of a UE are provided. The apparatus determines a brightness level of a display screen of the UE. The apparatus also sets a resolution mode of the display screen based on the brightness level.

Abstract: Techniques for efficiently managing resources are described. In an example, a computer system may access a forecast for demand associated with utilizing a service during a time period, where the service is available from service sources grouped in clusters. The computer system may identify resources scheduled to facilitate the service. Based on a scheduled start time for utilizing a resource, the forecast, and an allocation of remaining resources to the clusters, the computer system may allocate the resource to a first cluster and may provide a notification about the allocation to an associated client device. At a subsequent time during the time period, the computer system may re-allocate the resource to a second cluster based on a current utilization of the resource, an update to the forecast, and the allocation of the remaining resources. A respective notification may be provided to the client device.
