Abstract

There is provided a rescue requesting method using Bluetooth™ wireless communication technology. One of a plurality of Bluetooth™ devices that form a network generates a message packet requesting an emergency rescue in an emergency and transmits the message packet to the other Bluetooth™ devices in the network. A Bluetooth™ device receiving the message packet performs a predetermined rescue request operation in response to the message packet.

Claims

1. A rescue requesting method for use in one of a plurality of Bluetooth™

devices that form a network, comprising the steps of;

pressing, by a user, a predetermined hot key button on a mobile phone to invoke a rescue request program;

generating a message packet requesting an emergency rescue in an emergency, wherein the message packet has a value indicating a rescue request in a preset bit position; and

transmitting the message packet to the other Bluetooth™

devices in the network.

2. The rescue requesting method of claim 1, wherein the message packet is an FHS (Frequency Hopping Synchronous) packet.

3. The rescue requesting method of claim 2, wherein the FHS packet is transmitted in a remote name request procedure.

4. The rescue requesting method of claim 2, wherein the FHS packet is transmitted in a master-slave switching procedure.

5. A rescue requesting method for use in one of a plurality of Bluetooth™

devices that form a network, comprising the steps of;

receiving a message packet;

determining whether the received message packet is a request for an emergency rescue from another Bluetooth™

device in the network by detecting a value in a preset bit position; and

performing a predetermined rescue request operation in response to the message packet.

6. The rescue requesting method of claim 5, wherein the predetermined rescue request operation is at least one of vibration, bell sound, and character display at the receiving Bluetooth™

device.

7. The rescue requesting method of claim 5, further comprising the step of requesting rescue to a predetermined party in response to the message packet.
