Abstract
A method and an apparatus for system acquisition at a wireless device while maintaining a predetermined battery life span, include determining a level of remaining battery power upon entering an out of service state. A duty cycle, comprising a search time and sleep time, of acquisition attempts is determined such that the level of remaining battery power lasts for the defined battery life span. The duty cycle is determined by adjusting at least one of the search time and the sleep time, depending on how long the remaining battery power is required to last.
Claims75
A method of system acquisition at a wireless device while maintaining a defined battery life span, comprising:
- determining a level of remaining battery power upon entering a defined state;
- and
- setting a duty cycle of acquisition attempts such that the level of remaining battery power lasts for the defined battery life span while the wireless device is in the defined state.
An apparatus for channel acquisition at a wireless device while maintaining a defined battery life span, comprising:
- a power control unit configured to determine a level of remaining battery power upon entering a defined state;
- and
- a processor configured to set a duty cycle of acquisition attempts such that the level of remaining battery power lasts for the defined battery life span while the wireless device is in the defined state.
An apparatus for channel acquisition at a wireless device while maintaining a defined battery life span, comprising:
- means for determining a level of remaining battery power upon entering a defined state;
- and
- means for setting a duty cycle of acquisition attempts such that the level of remaining battery power lasts for the defined battery life span while the wireless device is in the defined state.
A computer-readable medium storing instructions thereon for channel acquisition at a wireless device while maintaining a defined battery life span, comprising:
- determining a level of remaining battery power upon entering a defined state;
- and
- setting a duty cycle of acquisition attempts such that the level of remaining battery power lasts for the defined battery life span while the wireless device is in the defined state.
A processor configured to execute instructions for channel acquisition at a wireless device while maintaining a defined battery life span, the instructions comprising:
- determining a level of remaining battery power upon entering a defined state;
- and
- setting a duty cycle of acquisition attempts such that the level of remaining battery power lasts for the defined battery life span while the wireless device is in the defined state.
