METHOD OF REMOTELY CONTROLLING LOCAL NETWORK DEVICES AND APPARATUS THEREFOR
First Claim
1. A method of remotely controlling one or more local network devices, the method comprising:
- periodically receiving an access request from each of the one or more local network devices in a local network, to which direct access from outside the local network is blocked;
if a connection between a first local network device of the one or more local network devices and a server located outside the local network is formed as a result of receiving the access request, determining whether a command to be transmitted to the first local network device exists; and
if it is determined that the command to be transmitted to the first local network device exists, transmitting the command to the first local network device while a connection is being formed, in order to control the first local network device.

Abstract
Provided is a method of remotely controlling local network devices. The method includes periodically receiving an access request from each local network device in a local network, to which direct access from the outside is blocked, if a connection between a local network device and a server located outside the local network is formed as a result of receiving the access request, determining whether a command to be transmitted to the local network device exists, and if it is determined that a command to be transmitted to the local network device exists, transmitting the command to the local network device while the connect is being formed to control the local network device.

11. A server used for remotely controlling one or more local network devices, the server comprising:
-
a receiver which periodically receives an access request from each of the one or more local network devices in a local network, to which direct access from the outside is blocked; a search unit which determines whether a command to be transmitted to a first local network device exists, if a connection between the first local network device and a server located outside the local network is formed as a result of receiving the access request; and a transmitter that, if it is determined that the command to be transmitted to the first local network device exists, transmits the command to the first local network device while the connection is being formed, in order to control the first local network device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A local network device used for a method of remotely controlling one or more local network devices, the local network device comprising:
-
a transmitter which periodically transmits an access request to a server; a receiver which receives a command from the server if a connection between the local network device and the server is formed as a result of transmitting the access request using the transmitter; and an operation controller which controls an operation to be performed based on the command. - View Dependent Claims (21)

22. A computer readable recording medium storing software instructions for enabling a computer to perform operations for remotely controlling local network devices, the operations comprising:
-
periodically receiving an access request from each of a plurality of local network devices in a local network, to which direct access form outside the local network is blocked; if a connection between a local network device and a server located outside the local network is formed as a result of receiving the access request, determining whether a command to be transmitted to the local network device exists; and if it is determined that the command to be transmitted to the local network device exists, transmitting the command to the local network device while a connection is being formed, in order to control the local network device.
