    摘要： Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

    摘要： A method for dynamically applying a battery saving technology by a terminal is disclosed. The method comprises transmitting a first message requesting an activation of a battery saving technology dynamic service to an authentication server, receiving a second message being a response to the first message from the authentication server, transmitting and receiving data with a base station in a battery saving technology deactivated state, when response information included in the second message comprises authentication success, and at least one application included in the second message is running, and maintaining a battery saving technology activated state when the application included in the second message is not running.

    摘要： The disclosure provides a control method for network disconnection during screen off and a mobile device. The control method is applicable to a mobile device, and includes: setting a network restriction list based on a plurality of applications of the mobile device, where an application run in a background in the applications is excluded from the network restriction list; determining, based on a system status of the mobile device, whether the system status meets a trigger condition, where the trigger condition is that a screen of the mobile device is off for more than a preset time, and there is no external power supply; and starting a network disconnection mechanism when the trigger condition is met, to restrict network connections of the applications in the network restriction list, and maintaining the network connections when the trigger condition is not met.

    摘要： Systems, methods, and computer readable media that schedules requests for location data of a mobile device, where the methods include selecting a first positioning system based on a power requirement, a latency requirement, and an accuracy requirement, and determining whether a first condition is satisfied for querying the first positioning system. The method further comprises in response to a determination that the first condition is satisfied, querying the first positioning system for first position data. The method further comprises in response to a determination that the first condition is not satisfied, selecting a second positioning system based on the power requirement, the latency requirement, and the accuracy requirement, determining whether a second condition is satisfied for querying the second positioning system, and in response to a determination that the second condition is satisfied, querying the second positioning system for second position data.

    摘要： Systems, methods, and computer readable media that determine a location of a device using multi-source geolocation data, where the methods include accessing new location data from a location source of a plurality of location sources, where the new location data includes a new position and an accuracy of the new position, and determining a current position and an accuracy of the current position based on the new position, the accuracy of the new position, an previous current position, and an accuracy of the previous current position. The method further includes determining a change in location based on a difference between the current position and the previous current position. Some systems, methods, and computer readable media are directed to scheduling location requests to generate location data where the scheduling and the actual requests are made based on a number of conditions.

    摘要： Embodiments herein provide a method performed by a user equipment (UE) for handling packet data convergence protocol (PDCP) duplication. In one embodiment, the method includes determining that a first criteria to deactivate the PDCP duplication is met based on a first device condition; and sending, to a base station, a first message indicating a first preference to deactivate the PDCP duplication. In other embodiment, the method also includes determining that a second criteria to activate the PDCP duplication is met based on a second device condition; and sending, to the base station, a second message indicating a second preference to activate the PDCP duplication.
