Description

  According to the present invention, three or more mobile communication terminals and a call control server are connected via a packet communication network, and the call control server is configured to receive the right to speak from the mobile communication terminal. The present invention relates to a mobile communication terminal used in a multi-party call system that gives a speaking right to any one of them.

  As a system in which multiple users have a group conversation using a mobile phone that is a mobile communication terminal, a call that gives the right to speak to a specific mobile communication terminal when making a call between mobile communication terminals A multi-party communication system using a control server, a so-called PoC (Push-to Talk over Cellular) server, is known. This multi-party communication system is generally called a PoC (Push-to Talk over Cellular) communication system. The PoC communication system is based on VoIP (Voice over IP) that enables communication between portable communication terminals on an IP (Internet Protocol) network.

  In a PoC communication system, a packet communication network is used, and not only a one-to-one call but also a call between many people can be performed. However, the PoC communication system makes a request for acquisition of the right to speak to the PoC server when the speaker presses a dedicated key of the mobile phone. When the voice acquisition permission is obtained from the PoC server, the voice data that is spoken is transmitted from the PoC server to another mobile phone via the network by speaking while pressing the dedicated key. A plurality of other mobile phones that have received the voice data cannot speak while the speaker continues to press the dedicated key, and only the voice data is received.

  Thus, in the PoC communication system, two or more people cannot speak at the same time. In the PoC communication system, another person requests the PoC server to acquire the right to speak, and after the person who is currently speaking has finished speaking, the person who has acquired the right to speak can speak. Specifically, when the floor holder who is speaking releases the dedicated key, no one is speaking, the floor is released, and while this floor is released, The user of the mobile phone that first makes a request to acquire the right to speak obtains the right to speak, and only that mobile phone can speak.

  This speaking right is managed by the PoC server, and the PoC server registers the member, grasps the member availability information such as “absence” and “occupancy” (presence function), and assigns the speaking right to a plurality of mobile phones ( Floor control).

  Furthermore, in the above PoC communication system, in order for a user of a mobile phone not speaking to take the right to speak, the right to acquire the right to speak is acquired after the right right holder stops speaking and the right to speak is released. It is necessary for a person other than the person to transmit a request to obtain the right to speak to the PoC server. However, when someone is speaking, of course, even if you are not speaking, if the PoC server sends a voice acquisition notification to someone else first, you can speak even if you want to speak. Can not do it. Also, if the person who is speaking continues to speak and does not give up the right to speak, the other person cannot speak for the duration and cannot express the will to speak. In addition, there is a method of sending text information as a means of transmitting an intention to speak, but it is difficult to transmit a text input in real time.

  Therefore, a PoC communication system has been proposed in which a floor is reserved for the PoC server, and each time the floor is released, the floor is given priority in the order of reservation registration to facilitate speaking (for example, Patent Document 1). According to the PoC communication system disclosed in Patent Document 1, it is possible to reserve the right to speak, so that the right to speak can be acquired in a fair order by giving the right to speak in the reservation registration order.

Audio data transmitting means for transmitting, audio data storing means for holding the audio data, and voice data storing means for storing the audio data when no speaking right is held Recording means for performing a recording process for writing, wherein the speaking right requesting means transmits the request for acquiring the right to speak based on the end of the recording process, and the audio data transmitting means transmits a message after the end of the recording process. When the right is acquired, the voice data held by the voice data storage means is transmitted.

  According to the mobile communication terminal of the first aspect of the present invention, when it is not possible to immediately speak to the speaker, the contents to be spoken are stored as voice data in the voice data storage means, and the right to speak is automatically acquired. When the request is made and the right to speak can be acquired, the voice data held by the voice data storage means can be automatically output to the call control server. As a result, the user does not need to grasp the contents to be spoken after the contents to be spoken until the user obtains his / her right to speak, and the user's stress is reduced.

  Specifically, the portable communication terminal according to the first aspect of the present invention provides the recording means when the right to speak can not be obtained from the call control server when it is optimal for the right to obtain the right to speak by the right request means. The contents to be spoken using can be recorded as voice data in the voice data storage means. Then, when the mobile communication terminal according to the present invention stores the voice data of the content to be spoken in the voice data storage means, the voice right storage means automatically transmits a voice right acquisition request, and the voice right When the acquisition means acquires the floor, the voice data transmission means can automatically output the voice data held in the voice data storage means to the call control server.

  In the mobile communication terminal according to the second aspect of the present invention, in addition to the above-described configuration, the voice data transmitting unit is configured to store the voice data output from the microphone for transmission and the voice data storage unit based on a user designation. One of them is selectively transmitted.

  With such a configuration, the mobile communication terminal according to the second aspect of the present invention, when acquiring the right to speak, the voice data recorded according to the content of the conversation at that time or the raw voice data is selected according to the user's selection. It can be output to the call control server. Specifically, in the mobile communication terminal of the present invention, the user has the voice data recorded in the voice data storage means output to the call control server or is generated by the microphone for transmission. It is possible to specify whether the voice data is directly output to the call control server, and to output the voice data according to the content of the conversation at that time to the call control server.

  In the mobile communication terminal according to a third aspect of the present invention, in addition to the above configuration, the speaking right requesting unit specifies that the user transmits the voice data held in the voice data storage unit to the call control server. During this time, it is configured to repeatedly transmit the request for acquiring the right to speak to the call control server until the right to speak speaks.

  According to the mobile communication terminal of the third aspect of the present invention, the user records the voice data of the contents to be spoken in the voice data storage means, and the user generates the raw voice data generated by the microphone for transmission. Until the user wants to output the voice to the call control server, in order to output the recorded voice data to the call control server, a request for acquisition of the right to speak can be made automatically until the right to speak is obtained. . As a result, the user can concentrate on the content of the conversation at that time without causing the stress of remembering the content of the statement.

  According to the mobile communication terminal of the present invention, even when a user who has not acquired the right to speak has received the right to speak next, even if the user does not remember the content he / she wants to speak, the voice data of the content he / she wants to speak The recorded voice data can be automatically transmitted to other speakers. In addition, in this case, the user does not need to remember the content he / she wants to speak, so he / she can concentrate on and participate in the conversation in real time.

Further, the call control server 2 responds to the request for acquiring the right to speak from each mobile phone 1 and outputs the right to speak to the mobile phone 1 that has been requested to acquire the right to speak. A permission notification unit 202 is also provided.

  Next, processing when a multi-party call is performed by the mobile phone 1 of the present embodiment will be described with reference to the flowchart of FIG. The mobile phone 1 according to the present embodiment starts a multi-party call when the user presses the PoC key 17. When the multi-party call is started and the user keeps pressing the PoC key 17, the right-to-speak request unit 211 of the other-party call control unit 21 performs the acquisition operation of the right-to-speak notification from the call control server 2 ( Step S101). If the speaking right requesting unit 211 determines that a speaking right releasing notification has been acquired (Yes in step S101), the speaking right requesting unit 211 requests the call control server 2 to acquire a speaking right ( Step S102).

  When the user continues to press the PoC key 17, the speaking right acquisition unit 212 determines whether or not a speaking right acquisition permission notification has been sent from the call control server 2 in response to the request to acquire the speaking right (step S103). When the speaking right acquisition permission notification is received (Yes in step S103), the user inputs content to be spoken from the microphone 15 for transmission, and the content of the speech is converted into voice data and is sent to the call control server 2. It is transmitted (step S104).

  The voice data transmitted to the call control server 2 is transmitted to another mobile phone 1 via the call control server 2. In addition, when the other-party call control unit 21 acquires the right to speak, the other-party call control unit 21 displays a sound indicating the acquisition of the right to speak on the display unit 13 or a sound notifying that the right to speak has been acquired from the receiver 14 for reception. Or alerts the user.

  In addition, when the speaking right acquisition permission notification is not received and the speaking right cannot be acquired (No in step S103), the other-party call control unit 21 displays that the speaking right has not been acquired. Or a sound that informs the user that the right to speak has not been acquired from the receiver 14 is notified.

  Next, the voice data recording unit 214 determines whether or not the user intends to record (record) the content he / she wants to speak to the call control server 2 (step S105). Whether or not the user intends to record the content of the utterance is determined by whether or not the user has operated the operation key 16 serving as a recording start key among the operation keys 16.

  When the voice data recording unit 214 determines that the user wants to record the content to be spoken (Yes in step S105), the voice data recording unit 214 writes and records the voice data of the content to be spoken in the voice data storage unit 20 (step S106). ). On the other hand, when the voice data recording unit 214 determines not to record the voice data (No in step S105), the speaking right requesting unit 211 waits for reception of a speaking right release notification.

  When the voice data starts to be recorded in the voice data storage unit 20 (step S106), the voice data recording unit 214 determines whether or not the voice data recording to the voice data storage unit 20 is completed (step S107). When recording of the voice data in the voice data storage unit 20 is completed (Yes in step S107), the user keeps pressing the PoC key 17 again, whereby the floor control unit 2 notifies the floor control server 2 of the floor control release request. An acquisition operation is performed (step S108). The acquisition operation of the floor release notification is performed until the floor release notification is acquired (No in step S108).

  Then, when the speaking right request unit 211 determines that the speaking right release notification has been acquired (Yes in step S108), the speaking right request unit 211 makes a request for acquiring the right to speak to the call control server 2. This is performed (step S109).

  When the user continues to press the PoC key 17, the speaking right acquisition unit 212 determines whether or not a speaking right acquisition permission notification has been sent from the call control server 2 in response to the request to acquire the speaking right (step S110). When the voice acquisition permission notification is received (Yes in step S110), the voice data output unit 213 automatically transmits the voice data recorded in the voice data storage unit 20 to the call control server 2 ( Step S111). The voice data transmitted to the call control server 2 is transmitted to another mobile phone 1 via the call control server 2.

  If the floor acquisition permission notification has not been received (No in step S110), the floor request unit 211 counts the number of floor acquisition requests after the audio data is recorded in the audio data storage unit 20. Then, it is determined whether or not the request for acquisition of the right to speak is the third time (step S112). When the request for acquiring the right to speak is made up to twice (No in step S112), the process returns to step S108, where it is determined whether or not the right to speak has been acquired, and a request for acquisition of the right to speak is made. If the request for obtaining the right to speak is the third time (Yes in step S112), the audio data recording unit 214 deletes the audio data recorded from the audio data storage unit 20 (step S113).

  In the above embodiment, the mobile phone 1 determines that the recorded data is not a valid speech at the next speech when the speech acquisition request is made three times in step S112, and erases the voice data. I am doing so. However, the number of utterance acquisition requests (retry times) for erasing audio data from the audio data storage unit 20 can be freely set.

  Further, the mobile phone 1 may confirm with the user whether or not to make a floor acquisition request in step S112. In this case, when the user determines that the request to acquire a right to speak is unnecessary, the voice data is erased as not being a valid statement at the time of speaking.

  Moreover, in the mobile communication terminal according to the present invention, the condition for transmitting the audio data stored in the audio data storage unit is not limited to the above embodiment, and can be set to other conditions. For example, according to the user's request, the mobile communication terminal is set to perform recording (storing) of voice data to the voice data storage unit and an automatic speaking right acquisition operation for outputting the voice data, It can be set not to record data.
