Patent ID: 8359001

Claim:
A method in a first mobile device comprises enabling the first mobile device to ring after changing the first mobile device from a silent mode to a regular mode in response to receiving a message from a second mobile device, wherein enabling the first mobile device further includes, receiving the message in the first mobile device, parsing the message to determine whether the message includes a pre-defined string, determining whether the first mobile device is in a switched-off mode, powering on the first mobile device if it is determined that the first mobile device is in the switched-off mode in response to receiving the message including the pre-defined string, changing the first mobile device from the silent mode to the regular mode after powering on the first mobile device or changing the first mobile device from the silent mode to the regular mode without powering on the first mobile device if it is determined that the first mobile device is not in the switched-off mode, identifying the location of the first mobile device by tracking the ringing sound generated by the first mobile device in response to a call made from the second mobile device, forwarding the message to an identification logic if the message includes the pre-defined string, determining whether the identification logic is in a sleep-mode, waking-up the identification logic in response to receiving the message if the identification logic is in the sleep-mode, generating a power-on signal in the identification logic after waking-up the identification logic, and sending the power-on signal to a power logic to enable the power-logic to power-on a processing logic.
