An interworking device of a fixed line phone is provided to re-transmit a call received by a mobile phone to a fixed line phone through a home telephone network so that a user can answer the call through the fixed line phone, and allow the user to make a call through the mobile phone when he wants to do it through the fixed line phone. A mobile phone transmission/reception module detects a bell sound of a mobile phone, requests bell ringing of a fixed line phone, and outputs a voice after the mobile phone is requested to receive. When a user picks up a receiver of the fixed line phone, the mobile phone transmission/reception module requests mobile phone reception from the mobile phone, and requests mobile phone origination based on a received call signal to relay communication. A fixed line phone transmission/reception module generates a signal for allowing the fixed line phone to ring a bell sound according to the request for ringing a bell sound, detects pickup of the received of the fixed line phone, and detects pressed number to relay them to the mobile phone so that the user can make a call with the mobile phone. A voice channel maintaining/managing module receives a voice from the mobile phone transmission/reception module and transfers it to the fixed line phone transmission/reception module, and transfers origination number received from the fixed line phone through the fixed line phone transmission/reception module to the mobile phone transmission/reception module. |
