Abstract

In this invention, a solution is shown to adapt a de- vice mode (on/off/sleep-mode) according to the dis- tance from the user. Up to now, the device mode could only be changed by the device itself. The technical problem is solved in this invention by using a separate discrete device, called tag, which communicates with the mobile device (via bluetooth, IrDA, etc.) and shuts it on or off or switches to a sleep mode, when the distance between the two de- vices gets too large. The advantages of such a solu- tion are:

Controlling a mobile device modevia an external tag

In this invention, a solution is shown to adapt a de-vice mode (on/off/sleep-mode) according to the dis-tance� from� the� user.� Up� to� now,� the� device� modecould only be changed by the device itself.

The technical problem is solved in this invention byusing� a� separate� discrete� device,� called tag, whichcommunicates with the mobile device (via bluetooth,IrDA, etc.) and shuts it on or off or switches to asleep mode, when the distance between the two de-vices gets too large. The advantages of such a solu-tion are:

•� � When the device gets� lost,� it� is� automaticallyturned off and fraud protected.

•� � When the device is apart from the user, it doesnot ring and redirects incoming calls to the mailbox.

•� � When the device gets close to the user again, thetag is used to authenticate the user

•� � The mode of the device can be displayed on thetag (e.g. indicating distance from device)

The invention is realized by using a “reduced capa-bility” separate device. The adaption of mode is con-trolled by the distance between the two devices.

Example: The tag can be mounted to a wrist watch. Inthe evening, the mobile device is placed in the livingroom and the tag is carried in the bed room, switchingthe phone into a silent redirecting mode to preventthe user being disturbed from sleep and callers fromnon-response.
