Energy Budgeted System Recovery

Abstract

This disclosure relates to energy budgeted cellular service recovery techniques. A wireless device may determine one or more energy budgets for service recovery. It may be determined that cellular service loss is currently occurring. Cellular service recovery may be attempted, where service recovery scan timing for the attempt to recover cellular service is determined based at least in part on the one or more energy budgets for service recovery.

Description

TECHNICAL FIELD[0001]The present application relates to wireless communication, including to techniques for a wireless device to perform system recovery in accordance with one or more energy budgets.DESCRIPTION OF THE RELATED ART[0002]Wireless communication systems are rapidly growing in usage. Further, wireless communication technology has evolved from voice-only communications to also include the transmission of data, such as Internet and multimedia content.[0003]Mobile electronic devices may take the form of smart phones or tablets that a user typically carries. Wearable devices (also referred to as accessory devices) are a newer form of mobile electronic device, one example being smart watches. Typically, wearable devices have relatively limited wireless communications capabilities and typically have smaller batteries than larger portable devices, such as smart phones and tablets. In general, it would be desirable to reduce the power requirements of communication devices. Theref...

AI Technical Summary

Benefits of technology

[0006]Recovering from loss of cellular service is commonly a heavily power consuming process, but battery power is also commonly a limited resource for wireless devices in general (and link budget limited devices in particular), so managing the power consumption resulting from cellular service recovery operations may be desirable. Techniques for managing cellular service recovery operations within one or more energy budgets may help support whatever balance is desired between maintaining service availability and preserving battery power / life. Such techniques may be of particular use for a wireless device that may be expected to have a cellular communication service coverage area with more frequent coverage gaps than other wireless devices, since such a wireless device may experience radio link failure and out-of-service conditions more frequently.

Problems solved by technology

Typically, wearable devices have relatively limited wireless communications capabilities and typically have smaller batteries than larger portable devices, such as smart phones and tablets.

The wireless device may be a link budget limited device, such as an accessory device with a relatively limited communication range, e.g., due to device design constraints.

Because of the relatively limited communication range of the wireless device, cellular communication service coverage for the wireless device may not be as widespread as for many other wireless devices, which may in turn result in the wireless device experiencing loss of cellular service more commonly than a wireless device with greater communication range.

Such techniques may be of particular use for a wireless device that may be expected to have a cellular communication service coverage area with more frequent coverage gaps than other wireless devices, since such a wireless device may experience radio link failure and out-of-service conditions more frequently.
