Information providing service system and method based on inter-device information exchange protocol

An information providing service method based on an inter-device information exchange protocol using a system including a plurality of devices on which a device architecture (DA) module and an information provision application for performing information exchange and remote control in a specific network on the basis of the standardized information exchange protocol are installed, and an information provision server, the method comprising:

• (a) periodically transmitting, at the information provision application installed on the respective devices, position information about the respective devices;
• (b) receiving, at the information provision server, the position information transmitted from the respective devices and managing the position information according to the respective devices;
• (c) receiving, at the information provision server, a signal generated by a sensing means installed at a predetermined position in a specific place and finding a position of the generated signal;
• (d) searching for, at an information provision application service module prepared in the information provision server, the same device position information as the position found in (c);
• and
• (e) transmitting predetermined guide information data to the information provision application of a device corresponding to the device position information searched in (d).
