Abstract

A method and apparatus for communicating with a target device in a personal area network (PAN), when a multi-function remote controller (MRC) is outside the coverage area of the target device. The apparatus includes a proxy device which automatically forms a virtual PAN by setting up a pairing link with the target device to control the target device. Accordingly, a user may continuously control the target device irrespective of the location of the MRC.

First claim

What is claimed is:

1. A method for remotely controlling a target device, the method comprising:
determining that the target device and a proxy device are within a wireless Personal Area Network (PAN) and a control device is outside of the PAN;
generating, by the control device, a message that enables the proxy device to communicate with the target device via the PAN, the message comprising a target address of the target device, a virtual source PAN identifier (ID) of the control device, and a virtual destination PAN ID of the target device which are converted by the proxy device to a destination address, a real source PAN ID, and a real destination PAN ID, respectively; and
transmitting the message to the proxy device,
wherein the message is transmitted using a short message service (SMS) via a cellular network, and the message further comprises an SMS sender number as authentication information to obtain, from the proxy device, authentication to control the target device,
wherein the message is generated by the control device using a mapping table that respectively corresponds the SMS sender number, the target address, the virtual source PAN ID, and the virtual destination PAN ID to a source address, the destination address, the real source PAN ID, and the real destination PAN ID, and
wherein the SMS sender number, the target address, the virtual source PAN ID, and the virtual destination PAN ID are converted by the proxy device using the same mapping table.

2. The method of claim 1 , wherein the message is an extended markup language (XML)-based message including information for a multi-function remote controller (MRC) to control the target device according to a Zigbee RF4CE standard.

3. The method of claim 1 , wherein the determining comprises determining whether the target device is within the coverage area based on whether a discovery process according to a Zigbee RF4CE standard is successfully performed by the control device.

4. A non-transitory computer-readable recording medium having embodied thereon a computer program for executing the method of claim 1 .

5. The method of claim 1 , wherein the virtual destination PAN ID corresponds to an ID assigned to a virtual PAN group including the target device, the proxy device, and the control device, and the target address corresponds to a reference number uniquely assigned to the target device, and
wherein the virtual PAN group excludes at least one target device connected to the proxy device within the wireless PAN.

6. A control device for controlling a target device, the control device comprising:
a processor configured to determine that the target device and a proxy device are within a wireless Personal Area Network (PAN) and generate a message that enables the proxy device to communicate with the target device via the PAN, the message comprising a target address of the target device, a virtual source PAN identifier (ID) of the control device, and a virtual destination PAN ID of the target device which are converted by the proxy device to a destination address, a real source PAN ID, and a real destination PAN ID, respectively; and
a processing unit configured to transmit the message to the proxy device,
wherein the message is transmitted using a short message service (SMS) via a cellular network, and the message further comprises an SMS sender number as authentication information to obtain, from the proxy device, authentication to control the target device,
wherein the message is generated by the control device using a mapping table that respectively corresponds the SMS sender number, the target address, the virtual source PAN ID, and the virtual destination PAN ID to a source address, the destination address, the real source PAN ID, and the real destination PAN ID, and
wherein the SMS sender number, the target address, the virtual source PAN ID, and the virtual destination PAN ID are converted by the proxy device using the same mapping table.

7. The control device of claim 6 , wherein the message is an XML-based message including information for multi-function remote controller (MRC) to control the target device according to a Zigbee RF4CE standard.

8. The control device of claim 6 , wherein the processor determines whether the target device is within the coverage area based on whether a discovery process according to a Zigbee RF4CE standard is successfully performed by the control device.
