METHOD FOR RELATING MOBILE TERMINALS BY VOICE INPUT

PROBLEM TO BE SOLVED: To provide a method for relating mobile terminals each other that can simply relate the terminals and allow the related terminals to make 2-way communication. SOLUTION: First and second terminals placed close to each other receive the same reference voice information and transmit the reference voice information respectively to a matching server. Then the matching server compares the reference voice information sets, relates each terminal to the same ID and registers the result to a database when the information sets show the same voice characteristic. Relating the terminals on the basis of the voice characteristic informs all the other terminals about a call to the matching server from any terminal after that in this way. Thus, the terminals are related to each other by the server without the need for complicated initialization through the so-called 'voice link', that is, the related terminals by voice and communication between the specific terminals can be facilitated.
