Adaptive paging signal in cordless telephone
First Claim
1. A cordless telephone comprising:
- a base unit, including a paging mechanism; and
a handset, including an alerting mechanism responsive to the paging mechanism, wherein at least one of the base unit and the handset includes a page adjusting mechanism to affect an alerting signal output from the alerting mechanism based on an estimate of the distance between the base unit and the handset, wherein the estimate is based on at least one measure related to a signal from the base unit to the handset, and at least one measure related to a signal from the handset to the base unit.

Abstract
In one embodiment, a cordless telephone according to the invention includes a base unit, including a paging mechanism, and a handset, including an alerting mechanism responsive to the paging mechanism. At least one of the base unit and the handset includes a page adjusting mechanism to affect an alerting signal output from the alerting mechanism based on a condition. Thus, the paging signal is adaptive to increase the opportunity for a user to determine the location of a misplaced handset. In another embodiment, a cordless telephone is equipped so that the base unit can provide an indication related to a distance between the base unit and the handset. In yet another embodiment, a cordless telephone is equipped so that the paging mechanism is adjusted based on user control. In a further embodiment according to the invention, a method is provided for affecting an alerting signal output by an alerting mechanism of a cordless telephone handset. The method includes the steps of sensing a condition, and affecting the alerting signal based on the sensed condition.
