  FIG. 3 is a conceptual diagram showing the overall configuration of the PTT communication system. The PTT communication system 2 is a system for a user 1 of the mobile phone 1 and other users 2 and 3 who use another communication device 201 to perform a group call. The operation content of the PTT communication system 2 will be described later with reference to FIG.

  The PTT communication system 2 includes a mobile phone 1, a communication device 201, a PTT server 202, and a communication network 203 connecting them. During a group call, communication between the mobile phone 1 and the communication device 201 is performed via the PTT server 202.

  The communication device 201 is a communication device having a group call function described in this embodiment, such as a mobile phone, a telephone, and a personal computer. Hereinafter, for convenience, it is assumed that the communication device 201 is a mobile phone of the same type as the mobile phone 1.

  The group call realized by the PTT communication system 2 is a half-duplex call method, that is, a method in which voice data for a call transmitted along the communication network 203 can be transmitted only in one direction at a time. Is adopted.

  The PTT server 202 manages the PTT communication system 2 as a whole so that group calls are properly performed.

  The communication network 203 connects the mobile phone 1, the communication device 201, and the PTT server 202 via the above-described base station so as to be capable of bidirectional communication. Various signals for group calls and voice data for group calls (hereinafter referred to as “PTT audio data”) are transmitted in the upstream direction (direction toward the PTT server 202) or vice versa via the communication network 203. Transmitted in the downstream direction.

  The PTT server 202 includes a CPU 202a and a communication unit 202b. The CPU 202a grants the right to speak to the communication device (mobile phone 1, communication device 201) that participates in the group call by giving the right to speak and manages the received PTT voice data for which the right to speak is acquired. In response to reception of a signal (key press information) including identification information received from the communication device (mobile phone 1, communication device 201) and processing to transmit to another communication device that is not connected (standard form) A voice command) is transmitted to the communication device (mobile phone 1, communication device 201) to which the right to speak is given. These signals and data are received or transmitted from the communication unit 202b. These processes executed in the PTT server 202 will be described in detail later with reference to FIGS. 6 and 8B.

  Here, the “speaking right” is a right to transmit the PTT voice data input from the microphone 12 to other communication devices participating in the group call. The right to speak is given by the PTT server 202 to the communication apparatus that has requested acquisition of the right to speak. Also, the acquisition of the right to speak by the user means that the communication device used by the user for the group call acquires the right to speak.

  Processing related to communication between the cellular phone 1 and the PTT server 202, management of the acquisition status of the right to speak, and the like for group calls using the PTT communication system 2 is executed by the CPU 100.

  FIG. 3 shows a configuration example of the PTT communication system 2 for 1: 2 communication between the mobile phone 1 and the two communication devices 201. However, in practice, by using the PTT communication system 2, a call between one communication device 201 (1: 1 communication) and a call between three or more communication devices 201 (1: N communication). N ≧ 3) is also possible. Hereinafter, as illustrated in FIGS. 3, 4, 6 and 9, the present embodiment will be described by taking the case of 1: 2 communication as an example.

  FIG. 4 is a diagram for explaining the contents of the basic operation of the PTT communication system 2. The direction of the arrow in the communication network 203 represents the direction in which the PTT audio data flows when the mobile phone 1 has acquired the right to speak.

  The management table in FIG. 5B is a table for explaining the value of the right to speak that is stored in the memory 101 and represents the acquisition status of the right to speak. The floor flag is set to a value of 0 when the floor is acquired, and is set to a value of 1 when the floor is not acquired. The initial value of the floor flag is 0. The speaking right flag is set by the CPU 100 according to the acquisition state of the speaking right of the group call.

  When a group call by using the PTT communication system 2 is started by the users 1 to 3, the PTT server 202 first receives a floor request signal from the mobile phone 1 or the communication device 201.

  For example, when a predetermined operation (for example, an operation of pressing the key 13) is performed by the user of the mobile phone 1, the CPU 100 transmits a speaking right request signal to the PTT server 202. When the PTT server 202 receives this floor request signal and there is no other communication device that gives the floor, the PTT server 202 transmits a signal informing the mobile phone 1 that the floor is granted. At the same time, the PTT server 202 starts a process of transmitting the PTT audio data received from the mobile phone 1 to a communication device (in this case, the communication device 201) that has not acquired the right to speak.

  When the CPU 100 acquires the right to speak, the CPU 100 sets the right to speak flag. While the mobile phone 1 acquires the right to speak, PTT sound data is generated based on the sound input from the microphone 12, and the generated PTT sound data is transmitted to the PTT server 202. Thereby, while the mobile phone 1 is acquiring the right to speak, the users 2 and 3 can listen to the user 1's remarks.

  While the key 13 continues to be pressed, the mobile phone 1 can continue to hold the right to speak. When the pressing of the key 13 is stopped, or when a predetermined time or more has elapsed after the key 13 is pressed even if the pressing of the key 13 is continued, the right to speak is canceled (the right to speak flag is Set to 0). When the speaking right flag is set to 0, the speaking right of the group call is not given to any communication device, and the PTT server 202 receives a new speaking right request signal. In this way, a group call is made using the PTT communication system 2.

  Now, in a group call using a conventional PTT communication system, a user who participates in a group call cannot speak unless he / she obtains the right to speak. In the configuration according to the present embodiment, even when one user acquires the right to speak, another user who does not acquire the right to speak immediately displays an intention to the group call participant. It has a configuration for making it possible. Below, the structure for enabling a user without a speaking right to display an instantaneous intention will be described.

  FIG. 5B is an example of a standard audio correspondence table. The standard voice correspondence table is a table that defines a correspondence relationship between the standard voice and an identification number (1 to 8 in the case of FIG. 5B) for specifying the standard voice. According to the fixed sound correspondence table of FIG. 5B, for example, the identification number 1 corresponds to the fixed sound “flapping” (the sound of applause expressing approval). The identification number 2 corresponds to the standard voice “boo-boo” (sound that indicates dissatisfaction / dissatisfaction).

  The memory 101 stores in advance the data of each standard voice (hereinafter referred to as “standard voice data”) together with the standard voice correspondence table of FIG. The other communication device 201 participating in the group call is a mobile phone having the same configuration as the mobile phone 1, and the same standard voice as that stored in the memory 101 of the mobile phone 1 is stored in the memory of the other communication device 201. A correspondence table (FIG. 5B) and standard audio data are stored in advance. Thereby, the mobile telephone 1 and the communication apparatus 201 can specify the same fixed audio | voice data based on the same identification number.

  Note that the correspondence table and the standard audio data may be configured to be newly or additionally acquired by various methods such as downloading and importing from an external storage medium.

FIG. 6 shows the cellular phone 1, the communication device 201, and the PTT when the user 2 of the communication device 201 that has not acquired the right to speak immediately displays an intention in the state where the cellular phone 1 has acquired the right to speak. It is a sequence diagram for demonstrating the signal (key press information, a fixed voice command) and PTT voice data transmitted / received between the servers. The left and right arrows in FIG. 6 indicate the direction in which a signal or PTT audio data flows. Further, the downward direction of the vertical axis is the time progression direction of the sequence diagram.

  FIG. 7 is a flowchart for explaining processing for transmitting PTT audio data, which is executed when the mobile phone 1 acquires the right to speak. FIG. 8A is a flowchart for explaining processing for transmitting key press information, which is executed when the mobile phone 1 has not acquired the right to speak. FIG. 8B is a flowchart illustrating a process for transmitting a standard voice command executed in the PTT server 202 to the mobile phone 1 or the communication device 201 that has acquired the right to speak.

  Note that the processing shown in FIGS. 7 and 8A is also executed in the communication apparatus 201 that is the same type as the mobile phone 1 during a group call. That is, the communication device 201 executes the process of FIG. 8A while the mobile phone 1 acquires the right to speak. Further, the communication apparatus 201 executes the process of FIG. 7 while it acquires the right to speak.

  The process of FIG. 7 will be described. First, the CPU 100 generates PTT voice data from the input voice input from the microphone 12 (S102) and transmits the PTT voice data to the PTT server 202 while a standard voice command (described later) is not received from the PTT server 202 (S101: NO). S103).

  As described with reference to FIG. 4, the PTT server 202 transfers the received PTT audio data to the communication apparatus 201 that has not acquired the right to speak. Such transmission of the PTT audio data is continued while the cellular phone 1 acquires the right to speak, that is, while the right to speak is set to 1 (S104: YES). Thereby, the users 2 and 3 of the communication device 201 can listen to the remarks of the user 1.

  While the cellular phone 1 holds the right to speak, the CPU 100 of the communication device 201 executes the process of FIG. In step S <b> 111, when any one of the “1” key to “8” key is pressed, the CPU 100 determines that an operation for designating the corresponding standard voice has been performed. That is, the CPU 100 determines that the standard voice having the number corresponding to the pressed key as the identification number is designated.

  For example, when the communication device 201 of the user 2 performs an operation of designating the standard voice “boo” by pressing the “2” key, the CPU 100 of the communication device 201 has performed an operation for expressing the intention using the standard voice. (S111: YES), key press information A1 (see FIG. 6) including an identification number corresponding to the pressed key is transmitted to the PTT server 202 (S113).

  While the communication device 201 does not acquire the right to speak (S112: NO), that is, while the right to speak is set to 0, the key press information A1 is stored in the PTT server 202 in response to the above-described operation for designating the standard voice. Sent to. When the communication apparatus 201 acquires the right to speak (S112: YES), that is, when the right to speak is set to 1, the process of FIG. 8A executed by the communication apparatus 201 is terminated.

  Now, during a group call, the PTT server 202 receives the key press information A1 while giving the right to speak to the mobile phone 1 or the communication device 201.

  6 and 8B, when the PTT server 202 receives the key press information A1 transmitted by the communication device 201 used by the user 2 (S121: YES), the PTT server 202 is designated by the key press information A1. The standard voice command A2 including the identification number is transmitted to the mobile phone 1 that has currently acquired the right to speak (S122). While the group call is being performed (S123: NO), the PTT server 202 executes the process of step S122 in response to the reception of the key press information A1.

  Returning to FIG. 7, when the CPU 100 receives the standard voice command A2 from the PTT server 202 in step S101 (S101: YES), the CPU 100 executes the processes of steps S105 to S108.

  First, the CPU 100 acquires, from the memory 101, standard voice data (“boo-boo”) corresponding to the identification number (No. 2) designated by the received standard voice command A2 (S105). Then, the CPU 100 generates PTT sound data A3 in which the standard sound is synthesized with the input sound input from the microphone 12 (S106). Then, the CPU 100 transmits the generated PTT audio data A3 to the PTT server 202 (S107).

  Thus, the PTT audio data A3 transmitted from the mobile phone 1 is transferred by the PTT server 202 to another communication apparatus 201 that has not acquired the right to speak.

  When the communication device 201 used by the users 2 and 3 receives the PTT audio data A3, the audio based on the PTT audio data A3 is output from one or both of the speakers 14 and 22 of the communication device 201 used by the users 2 and 3. The In the output voice, the standard voice representing the intention expressed by the user 2 is synthesized with the voice uttered by the user 1. The user 3 who has not acquired the right to speak can recognize an expression of intention from another user who has not acquired the right to speak by listening to the synthesized speech of the standard speech output in this way.

  As shown in the sequence diagram of FIG. 6, the key press information A1, the standard voice command A2, and the PTT voice data A3 are transmitted and received at any time, even while the mobile phone 1 is acquiring the right to speak, and specified by the user 2 The standard voice is immediately played back on the mobile phone 1 and the communication device 201.

  FIG. 9 shows the cellular phone 1, the communication device 201, and the PTT server when the user 1 of the cellular phone 1 immediately displays a will to the group call participant in a state where the cellular phone 1 has not acquired the floor. FIG. 6 is a sequence diagram for explaining the flow of signals (key press information, fixed voice commands) and PTT voice data transmitted / received to / from 202.

  When the communication device 201 of the user 2 has acquired the right to speak, the communication device 201 operates in the same manner as the mobile phone 1 in a state in which the right to speak is acquired. In this case, the cellular phone 1 in a state where the floor has not been acquired operates in the same manner as the communication device 201 of the user 2 described above. That is, the CPU 100 of the mobile phone 1 transmits the key press information B1 according to the flowchart shown in FIG.

  Also in the case of FIG. 9, as in the case of FIG. 6, the key press information B <b> 1, the standard voice command B <b> 2, and the PTT voice data B <b> 3 are obtained even while the communication device 201 of the user 2 acquires the floor. The fixed voice that is transmitted and received at any time and specified by the user 1 is immediately played back on the mobile phone 1 and the communication device 201.

As described above, according to the configuration of the present embodiment, in a state in which the mobile phone 1 has acquired the right to speak (FIG. 6), the CPU 100 of the mobile phone 1 has the standard voice designated by the user who has not acquired the right to speak. When the standard voice command A2 based on the standard voice command A2 is received, the PTT voice data A3 is generated by synthesizing the standard voice corresponding to the identification number included in the standard voice command A2 with the input voice input by the microphone 12, and the PTT server 202.

  Therefore, even when the mobile phone 1 has acquired the right to speak, the user of the communication device 201 that does not have the right to speak can immediately display the intention to the participant of the group call.

  Further, the same standard voice correspondence table and the standard voice data are stored in the memory 101 of the mobile phone 1 and the communication device 201. In addition, by transmitting the key press information A1 and the standard voice command A2, the CPU 100 of the mobile phone 1 uses the standard voice designated by the user who does not have the right to make an intention from the identification number included in the standard voice command A2. The same fixed voice can be specified.

  In addition, in a state where the mobile phone 1 does not acquire the right to speak and the other communication device 201 acquires the right to speak (FIG. 9), the user 1 is pressed when the standard voice is designated by pressing a predetermined key. Key press information B 1 including an identification number corresponding to the key is transmitted to the PTT server 202. When the PTT server 202 transmits the standard voice command B2 to the communication apparatus 201 that has acquired the right to speak, the communication apparatus 201 generates PTT voice data B3 based on the standard voice specified by the user 1. The PTT audio data B3 is transmitted by the PTT server 202 to the mobile phone 1 and the communication device 201 that do not have the right to speak and is played back. Therefore, even when the mobile phone 1 has not acquired the right to speak, the user 1 of the mobile phone 1 can immediately display a will to the participants of the group call.

  In addition, when the mobile phone 1 has acquired the right to speak, when the standard voice command A2 is received, the standard voice based on the standard voice command A2 is output from the speakers 14 and 22 of the mobile phone 1. Therefore, the user 1 of the mobile phone 1 can know the immediate intentions of the other users 2 and 3 who are listening to the user 1 when the user 1 is speaking.

<Example of change>
FIG. 10 is a flowchart for describing processing for transmitting PTT audio data, which is executed when the mobile phone 1 has acquired the right to speak, according to a modification. Note that the processing in FIG. 10 is also executed when the communication apparatus 201 has acquired the right to speak.

  The flowchart in FIG. 10 is obtained by replacing the process in step S106 in the flowchart in FIG. 7 with the process in step S131.

  In step S131, the CPU 100 synthesizes the standard voice with the input voice so that the volume of the standard voice is lower than the volume of the input voice from the microphone 12. The CPU 100 adjusts the volume of the standard voice to a level that does not hinder the user 1 who is the speaker from listening to the content of the speech. For example, the volume of the standard voice is set to a certain rate (for example, about several tens of percent) smaller than the maximum value of the volume of the input voice for the past predetermined time (for example, about several seconds) input from the microphone 12.

  When the volume of the input voice is so low that it is assumed that the user 1 is not speaking (for example, the volume of the background noise is low), the CPU 100 has a volume that can be heard by the participant. The standard voice is synthesized with the input voice at a predetermined fixed volume.

As described above, according to the configuration of this modified example, the PTT sound data is generated by synthesizing the fixed sound and the input sound so that the sound volume of the fixed sound is smaller than the sound volume of the input sound. As a result, in the PTT sound output from the mobile phone 1 or the communication device 201 that has not acquired the right to speak, the sound uttered by the user having the right to speak is larger than the synthesized standard sound. Therefore, a user who does not have the right to speak can listen to the remarks of the user who has the right to speak without being blocked by the standard voice.

  When the voice uttered by the user 1 is high, the volume of the standard voice is set high, and when the voice uttered by the user 1 is low, the volume of the standard voice is set low. For this reason, in a group call, it is suppressed that one of the voice and the standard voice of the user who has the right to speak reduces the audibility of the other, and the audibility of both the voice and the standard voice is suppressed. Balance is kept moderate.

<Others>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made to the embodiments of the present invention. .

  In the above embodiment, when receiving the standard voice command, the CPU 100 synthesizes the standard voice corresponding to the identification number included in the standard voice with the input voice from the microphone 12 when the standard voice command is received. PTT audio data is generated (S106). However, during the process of generating the PTT sound in step S106, the PTT sound data may be generated only from the standard sound without including the input sound. In this case, for example, if there is a voice input from the microphone 12 when the standard voice command A2 is received, the standard voice is transmitted when the voice input is interrupted (when there is no voice signal).

  In the above-described embodiment, when the CPU 100 receives the standard voice command A2 in a state where the mobile phone 1 has acquired the right to speak, the mobile phone 1 uses the standard number corresponding to the identification number included in the standard voice command A2. Audio is played back. However, a configuration in which a predetermined vibration corresponding to the identification information is output from the vibrator 15 instead of the standard voice may be employed. In this case, the memory 101 stores a vibration pattern of the vibrator 15 corresponding to the identification information in advance.

  Further, instead of outputting the predetermined vibration from the vibrator 15, a configuration in which the key backlight 111 displays the predetermined illumination may be employed. In this case, the memory 101 stores an illumination pattern of the key backlight 111 corresponding to the identification information in advance.

  According to the configuration of the above embodiment, the standard audio correspondence table illustrated in FIG. 5B and the standard audio data corresponding thereto are stored in the memory 101. The standard voice correspondence table in FIG. 5B is merely an example, and the standard voice registered in the standard voice correspondence table is not limited to the voice listed in FIG. , Music, etc. may be arbitrarily determined.

  Further, the number of standard voices registered in the standard voice correspondence table need not be limited to eight as shown in FIG. 5B, and a configuration with more or less than this may be adopted.

  The identification number for specifying the standard voice is sufficient if it is identification information in a format that can specify the standard voice, and need not be a number. The identification information may be expressed in various forms such as a code such as an alphabet corresponding to the standard voice, a label, and the like.

According to the configuration of the above embodiment, PTT audio data based on the standard audio corresponding to the received identification information is generated and transmitted to another communication device in a state where the floor is acquired. However, the mobile phone 1 may be configured such that such PTT audio data based on the standard audio is not generated. In this case, when a predetermined key is pressed in a state where the right to speak is not acquired, key press information (A1) corresponding to the key is stored in the PTT server 20.
2 is transmitted.

  In the above embodiment, the present invention is applied to a foldable mobile phone. However, the present invention is not limited to this, and the present invention may be applied to other types of mobile phones such as a straight type and a slide type.

Furthermore, the present invention is not limited to a mobile phone, but a PDA (Personal Digital Assistant),
The present invention can be applied to various communication devices including portable terminal devices such as tablet PCs and electronic book terminals.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
