Abstract

A mobile device providing position data of its own, the mobile device including: a Zigbee communication module executing Zigbee communication according to IEEE 802.15.4 standards; a global positioning system (GPS) module receiving a GPS signal and obtaining the position data of the mobile device; and a mobile communication module checking whether the mobile device departs a Zigbee communication network while executing the Zigbee communication via the Zigbee communication module, obtaining the position data of the mobile device via the GPS module when the mobile device departs the Zigbee communication network, and transmitting a position signal including the position data to a predetermined destination address.

Claims

1. A mobile device providing position data of its own, the mobile device comprising:

a Zigbee communication module executing Zigbee communication according to IEEE 802.15.4 standards;

a global positioning system (GPS) module receiving a GPS signal and obtaining the position data of the mobile device; and

a mobile communication module checking whether the mobile device departs a Zigbee communication network while executing the Zigbee communication via the zigbee communication module, obtaining the position data of the mobile device via the GPS module when the mobile device departs the Zigbee communication network, and transmitting a position signal comprising the position data to a predetermined destination address.

2. The mobile device of claim 1, wherein the position signal is a short message service (SMS) signal comprising the position data of the mobile device.

3. The mobile device of claim 1, wherein the position signal comprises Zigbee communication network departure information.

4. The mobile device of claim 1, wherein the mobile communication module determines that the mobile device departs the Zigbee communication network, when an intensity of a Zigbee communication signal received via the Zigbee communication is smaller than a reference value.

5. A method of obtaining position data, at a mobile device comprising a zigbee communication module executing Zigbee communication according to IEEE 802.15.4 standards;

a GPS module receiving a GPS signal and obtaining position data of the mobile device; and

a mobile communication module obtaining the position data of the mobile device by using the GPS module and the GPS module and transmitting a position signal comprising the position data to a predetermined destination address, the method comprising;

initiating the mobile device and the Zigbee communication module;

executing zigbee communication by using the Zigbee communication module and providing the position data of the mobile device to a coordinator of a Zigbee communication network;

checking whether the mobile device departs the Zigbee communication network while executing the Zigbee communication; and

obtaining the position data of the mobile device via the GPS module when the mobile device departs the Zigbee communication network and transmitting the position signal comprising the position data to the predetermined destination address.

6. The method of claim 5, wherein the position signal is an SMS signal comprising the position data of the mobile device.

7. The method of claim 5, wherein the position signal comprises departure information indicating that the mobile device departs the Zigbee communication network.

8. The method of claim 5, wherein the mobile communication module determines that the mobile device departs the Zigbee communication network, when an intensity of a Zigbee communication signal received via the Zigbee communication is smaller than a reference value.

9. The method of claim 5, wherein the obtaining of the position data of the mobile device and transmitting of the position signal is repeatedly performed until the Zigbee communication network is detected.

10. The method of claim 5, wherein the obtaining of the position data of the mobile device and transmitting of the position signal comprises:

starting operation of the GPS module;

obtaining the position data of the mobile device via the GPS module;

transmitting the position data of the mobile device to the predetermined destination address via the GPS module; and

executing the obtaining of the position data when the Zigbee communication network is not searched and finishing the obtaining of the position data and transmitting of the position signal when the Zigbee communication network is detected.
