Description

  The present invention relates to a wireless terminal having a function of participating in a PTT system and a PPT system, and a management server.

  The PTT (Push To Talk) system is a technology that realizes a transceiver-type call system of “push” and “speak”. Instead of dialing the other party's phone number like a popular mobile phone, it is only necessary to select a partner who can talk and press a button, and the connection can be made in just a few seconds. In the PTT system, it is possible to establish a group with a plurality of wireless terminals capable of making a call, and transmit voice from one wireless terminal in the group to another wireless terminal. In the conventional PTT system, when a session for a call within a group is established, information corresponding to each other's telephone number is exchanged. When the speaker speaks, the receiver can identify which member of the group is speaking by identifying the speaker by text information displayed on the wireless terminal or by the transmitted voice itself. Yes.

  Here, an operation of exchanging information between wireless terminals in the group via the PTT management server will be described. There can be three or more wireless terminals in the group. Here, a case where there are two wireless terminals is shown. A conventional wireless terminal includes an antenna, a wireless control unit, an output unit, an input unit, a speaker, a wireless terminal control unit, a push button, and a microphone. When a speaker sends voice, he / she operates a push button of his / her wireless terminal and emits voice to the microphone. The wireless terminal control unit of the wireless terminal of the sender transmits the voice input from the microphone to the PTT management server wirelessly via the antenna. The PTT management server selects all the wireless terminals in the group except the sender, and sends the voice sent from the sender to the receiver. The wireless terminal of the receiver receives the voice wirelessly via the antenna, and outputs the voice of the sender from the speaker under the control of the wireless terminal control unit. In addition, character information is displayed on the output unit based on the sender information corresponding to the telephone number sent together with the voice.

  Here, in order to identify who the speaker is, the receiver listens to the sound emitted from the speaker and identifies the speaker by himself or confirms the character information displayed on the output section. Had identified by.

  Since the conventional wireless terminal is configured as described above, in the PTT system, in order to identify the speaker, the receiver can display the voice output from the speaker or the output unit. It was necessary to make a judgment based on the text information. When a speaker tries to identify a speaker by voice, there is a problem that it becomes difficult to identify the speaker if the voice quality is bad, such as when the radio wave condition is bad. In addition, when the listener wants to identify the sender with the character information, it is necessary to always look at the output unit and read the character information, which causes a problem that the convenience of the user is impaired. Furthermore, in the conventional PTT system, since the receiver receives only limited information such as the voice and text information of the speaker as the information of the speaker, the convenience of the speaker and the receiver is low. There were also challenges.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a wireless terminal, a management server, and a PPT system that are improved in convenience for a sender and a receiver.

  The wireless terminal according to the present invention is selected from voice acquisition means for acquiring voice uttered by a talker, storage means for storing identification information for identifying the talker, acquired voice, and storage means. Received from the management server, wireless terminal control means for transmitting the identification information to the wireless terminals of the receivers in the same group via the management server, output means for outputting the identification information of the sender received from the management server, and And a sound generation means for outputting the voice of the sender.

  According to the present invention, the wireless terminal includes a voice acquisition unit that acquires a voice uttered by the speaker, a storage unit that stores identification information for identifying the speaker, the acquired voice, and the storage unit. Wireless terminal control means for transmitting the selected identification information to the wireless terminals of the receivers in the same group via the management server, output means for outputting the identification information of the sender received from the management server, and the management server And a sound generator that outputs the voice of the speaker received from the receiver, so that the receiver can easily identify the speaker and obtain information about the speaker in addition to the voice.
