MOBILE COMMUNICATION TERMINAL AND SIGNAL RELAY METHOD
First Claim
1. A mobile communication terminal for use in signal relay for relaying transmission signals, which are audio signals or video signals created by a plurality of transmission source terminals, to a transmission destination terminal that is connected via a mobile communication network, comprising:
- inputting means for creating a first transmission signal, which is an audio signal or a video signal, based on audio or video directly input from outside;
short-range communication means for receiving second transmission signals, which are audio signals or video signals, from the plurality of transmission source terminals via short-range communications;
signal synthesizing means for synthesizing the first transmission signal with the second transmission signals transmitted from the plurality of transmission source terminals, and outputting a synthesized signal;
signal selecting means for selecting a signal from among the first transmission signal, the second transmission signals, and the synthesized signal; and
signal transmitting means for transmitting the signal selected by the signal selecting means to the transmission destination terminal via the mobile communication network.

Abstract
An object of the present invention is to lower communication costs using a simple configuration by reducing traffic on a communication network resulting from data communications for video conference use. A mobile communication terminal has an audio/video input portion which creates a parent terminal transmission signal including an audio signal and a video signal directly input from outside, a short-range communication portion which receives child terminal transmission signals including audio signals and video signals from a plurality of mobile communication terminals via short-range communications, a signal synthesizer which synthesizes the parent terminal transmission signal with the plurality of child terminal transmission signals and outputs a synthesized signal, a switching portion which selects a signal from among the parent terminal transmission signal, the child terminal transmission signals and the synthesized signal, and a mobile communication portion which transmits the signal selected by the switching portion to a mobile communication terminal via a mobile communication network.
