Patent ID: 8666443

Claim:
A method for muting a sounder device, comprising steps of: binding said sounder device to a network terminal via a network, said binding including authenticating the network terminal and the sounder device to each other, and indicating that the network terminal and the sounder device belong to one person, the network terminal and the sounder device each being capable of a muting process; generating a muting requirement and sending a muting signal to said sounder device via said network, said muting signal being generated based on said muting requirement, said sounder device being configured to perform a muting process in response to said muting signal, wherein the network terminal performs muting processing as necessary and sends a muting instruction directly to the sounder device, which verifies the received instruction is from an authenticated network terminal after receiving the instruction, and if yes, the sounder device performs a muting process, and otherwise, the sounder device performs no process; and sending a recovery signal to the sounder device via said network if the muting requirement becomes invalid, the sounder device being configured to recover a status before the muting process upon said recovery signal, wherein the network terminal generates a recovering instruction and sends it directly to the sounder device, which verifies the received instruction is from an authenticated network terminal after receiving the instruction, and if yes, the sounder device performs a recovery process, and otherwise, the sounder device performs no process.
