Data format conversion device for wire/wireless local-area communication between wireless portable terminal and wire communication device and wire/wireless communication system using the same

摘要

A system wherein a mobile terminal can control the operation of an external communication device using wire/wireless local-area communication. The mobile terminal includes a local-area wireless communication module, and acts to perform the local-area wireless communication using the local-area wireless communication module. The communication device accesses an Internet communication network in response to an Internet access command input thereto to perform wire Internet communication. A wire/wireless data format conversion device is provided to perform the local-area wireless communication with the mobile terminal and wire communication with the communication device, and, in order to enable communication between the mobile terminal and the communication device, convert the format of received data into a format recognizable by a destination device, said destination device being one of the mobile terminal and communication device, and send the resulting data to the destination device over a corresponding transmission channel. The wire/wireless data format conversion device, upon receiving the Internet access command from the mobile terminal, converts the format of the received Internet access command into one recognizable by the communication device and sends the resulting Internet access command to the communication device and, upon receiving Internet access result information from the communication device, converts the format of the received result information into one recognizable by the mobile terminal and transmits the resulting result information to the mobile terminal.
