    • PROBLEM TO BE SOLVED: To provide a multiparty calling method utilizing a mobile communication terminal preventing an audio error of a call in a multiparty call service.
      SOLUTION: A multiparty calling method utilizing a mobile communication terminal includes: originating a call from a third user to a first user during a call between the first user and a second user; holding the call with the second user by the first user and terminating the call from the third user; setting a flag into a mobile communication terminal of the first user when the first user transfers a multiparty call join command; generating a tone by canceling the call between the first user and the third user when a connection cancel message is received before the lapse of predetermined time from reception of a success message of the above command; and judging whether the flag is set when the call between the first user and the second user becomes active and a connection cancel event is sent to the mobile communication terminal of the first user.

    • PROBLEM TO BE SOLVED: To provide a technology capable of transmitting a voice separated in each speaker when voice communication is performed in a state that a plurality of communication terminals are cascade-connected.
      SOLUTION: When a conference starts, participants using individual terminals 10-n give their statements. A voice data generation part 106 of each of the terminals 10-n collects voices of the participants and generates voice data. The generated voice data are transmitted to the other terminals 10-n. On the other hand, each of the terminals 10-n judges the existence of pronunciation in each of sound signals of a plurality of channels received from the other terminals 10-n and assigns an input channel detected as a pronunciation state to either one of a plurality of output channels.

    • 要解决的问题:提供一种能够在多个通信终端级联连接的状态下执行语音通信时能够发送在每个说话者中分离的语音的技术。

      解决方案:会议开始时,使用个人终端10-n的参与者发表声明。 每个终端10-n的语音数据生成部分106收集参与者的语音并产生语音数据。 生成的语音数据被发送到其他终端10-n。 另一方面,终端10-n中的每一个判断出从其他终端10-n接收到的多个频道的声音信号中是否存在发音,并且将检测为发音状态的输入频道分配给 多个输出通道。 版权所有(C)2009,JPO&INPIT
