Abstract
A mobile station capable of accessing a wireless communication network having a plurality of base stations is provided. The mobile station is configured to determine if a battery level of the mobile station is below a selected one of a plurality of power level thresholds. The mobile station is also configured to, upon a determination that the battery level is below the selected power level threshold, send a battery report to a first base station of the wireless communication network. The mobile station is further configured to enter a battery power preservation mode. The battery power preservation mode may include an enhanced idle mode, an enhanced sleep mode, or a persistent allocation mode.
Claims21
A mobile station capable of accessing a wireless communication network comprising a plurality of base stations, the mobile station comprising processing circuitry configured to:
- determine if a battery level of the mobile station is below a selected one of a plurality of power level thresholds;
- upon a determination that the battery level is below the selected power level threshold, send a battery report describing the battery level is below the selected power level threshold to a first base station of the wireless communication network, and enter a battery power preservation mode;
- in case of handover being triggered, conduct the handover from the first station to a second base station, maintaining the battery power preservation mode;
- determine if the battery level of the mobile station rises to the selected power level threshold;
- upon a determination that the battery level of the mobile station rises to the selected power level threshold, send a cancellation message cancelling the battery report to either the first base station or the second base station if the handover has been conducted, and exit the battery power preservation mode;
- and
- upon receiving a denial of entering the battery power preservation mode from the base station, refrain from entering the power reservation mode.
A base station in a wireless communication network, the base station capable of communicating with a plurality of mobile stations, the base station comprising processing circuitry configured to:
- receive a battery report describing a battery level is below a selected power level threshold from a first of the mobile stations;
- determine if the first mobile station is eligible to enter a battery power preservation mode;
- upon a determination that the first mobile station is eligible to enter the battery power preservation mode, enter the battery power preservation mode for the first mobile station;
- transmit information associated with the battery report to a target base station in case of a handover of the mobile station from the base station to the target base station;
- receive a cancellation message canceling the battery report from the first of the mobile stations;
- determine if the first mobile station is eligible to exit the battery power preservation mode;
- and
- determine that the first mobile station abused a previous battery power preservation mode, and deny the request to enter the battery power preservation mode.
A wireless communication network comprising a plurality of base stations, each base station capable of communicating with a plurality of mobile stations, each base station comprising processing circuitry configured to:
- receive a battery report from a first of the mobile stations;
- determine if the first mobile station is eligible to enter a battery power preservation mode;
- upon a determination that the first mobile station is eligible to enter the battery power preservation mode, enter the battery power preservation mode for the first mobile station;
- transmit information associated with the battery report to a target base station in case of a handover of the mobile station from the base station to the target base station;
- receive a cancellation message cancelling the battery report from the first of the mobile stations;
- determine if the first mobile station is eligible to exit the battery power preservation mode;
- and
- determine that the first mobile station abused a previous battery power preservation mode, and deny the request to enter the battery power preservation mode.
