Mobile telephone power savings method and apparatus responsive to mobile telephone location
First Claim
1. A method for saving power within a mobile telephone, comprising the steps of:
- determining coordinates of a present position of the mobile telephone; and
storing the coordinates in a memory associated with the mobile telephone as at least one predetermined location;
determining whether the current location of the mobile telephone is within a selected distance of the at least one predetermined location; and
operating the mobile telephone according to a first mode of operation when the mobile telephone is within the selected distance of the at least one predetermined location and according to a second mode of operation when the mobile telephone is not within the selected distance of the at least one predetermined location, wherein the first mode of operation uses less power than the second mode of operation.

Abstract
A mobile telephone able to save power in response to the position of the mobile telephone is disclosed. Location circuitry within the mobile telephone enables the establishment of one or more deep-sleep locations associated with a mobile telephone. When the location circuitry determines that the current location of the mobile telephone is within a selected distance of one of the deep-sleep locations, the mobile telephone operates according to a low power mode of operation wherein only a timer enabling periodic updates of the mobile telephone'"'"'s position is active. If the location circuitry determines that the mobile telephone is not within a selected distance of one of the predetermined locations, the mobile telephone operates in a standby mode which utilizes more power than the deep-sleep mode but still conserves battery power and enables the mobile telephone to receive calls.

16. A method for saving battery power within a mobile telephone, comprising the steps of:
-
storing at least one predetermined location within a memory; storing at least one base station identifier serving the at least one predetermined location within the memory; determining whether a base station identifier of a base station currently serving the mobile telephone matches the at least one base station identifier serving the at least one predetermined location; operating the mobile telephone according to a second mode of operation if the identifier of the base station currently serving the mobile telephone matches none of the at least one base station identifier serving the at least one predetermined location; determining a current location of the mobile telephone if the identifier of the base station currently serving the mobile telephone matches the at least one base station identifier serving the at least one predetermined location; comparing the current location with the predetermined location to determine if the mobile telephone is within a selected distance of the predetermined location; and operating the mobile telephone according to a first mode of operation when the mobile telephone is within the selected distance of the at least one predetermined location and according to the second mode of operation when the mobile telephone is not within the selected distance of the at least one predetermined location, wherein the first mode of operation uses less power than the second mode of operation. - View Dependent Claims (17, 18, 19, 20)
