Description

  The present invention relates to a call management device, a call management system, and a program.

  A PoC (Push to talk over Cellular) service is known as one of the call services for mobile phones (hereinafter referred to as “terminals”). The PoC service is a call service that registers a party to be communicated with and realizes half-duplex communication between a plurality of terminals so that a voice call or the like can be performed in a chat style with the registered party. In this call service, voice data of this utterance is broadcast to the other terminals of the participating member only when the user utters while pressing a predetermined button on the terminal (PTT: Push To Talk). It is like that. Also, voice data is not transmitted from another terminal to a terminal that is speaking when a predetermined button is pressed.

  Specifically, the PoC service is, for example, a predetermined server connected to a plurality of terminals of meeting participating members provided with the above-described predetermined button (hereinafter referred to as “PTT button”) via a communication network. (Hereinafter referred to as “call management device”). Here, the call management device has a function of controlling relay of communication between a plurality of terminals used by the meeting participating members. For example, when the call management apparatus receives a predetermined signal associated with pressing of the PTT button from one terminal among a plurality of terminals, the call management apparatus permits simultaneous transmission of audio data from the terminal to all other terminals. Is configured to do. As a result, the terminal whose PTT button is pressed can simultaneously transmit the voice data of the user's utterance to all other terminals.

  According to this PoC service, when a plurality of users distant from each other have a conversation as a group, this conversation can be established using their own terminals. However, as described above, when a certain terminal of the plurality of terminals occupies the right to speak, other terminals cannot acquire the right to speak. Therefore, a technique for effectively allocating the right to speak to each terminal is disclosed. For example, there is disclosed a call management device having a function of setting a priority order for acquiring a right to speak according to a time when a PTT button is pressed and preferentially giving a right to a terminal having a high priority ( For example, see Patent Document 1.) In addition, for example, a call management device having a function of predetermining a predetermined time during which a speech right can be occupied and displaying the speech right occupation time of a terminal to which the speech right is granted on a display of another terminal is also disclosed. (For example, refer to Patent Document 2).

However, for example, a plurality of users who make up the above-described group do not actually face each other, so it is not easy to recognize the end of each other's utterance from each other. This may hinder the smooth progress of calls within the group. Therefore, each user utters “please”, “over”, etc., which are phrases indicating the end of the utterance, at the end of his / her call, that is, immediately before releasing the pressed PTT button. We are trying to facilitate calls.

The voice data for notifying the voice data and the release of the right to speak with a voice phrase is received from the base station 2 in a communicable state via the call management server 10.

  The radio transmission / reception unit 201 transmits the call control message output from the PTT transmission / reception unit 202, voice data of the content of the call, and the like to the nearest base station 2, and releases the right to speak from other terminals 20 using a voice phrase. The voice data for notification is received from the base station 2 in a state where communication is possible via the call management server 10.

  The memory | storage part 203 memorize | stores the phrase number which identifies the audio | voice phrase corresponding to the audio | speech data for notifying release of a speech right stored in the database 13 (FIG. 1). In the present embodiment, the information specifying the voice phrase included in the call control message described above corresponds to this phrase number. Note that the storage unit 203 of the present embodiment stores information indicating the content of the audio phrase (for example, “male voice“ please ”) and the corresponding phrase number. The storage unit 203 shares a phrase number for identifying a voice phrase with the database 13. For example, if a user selects a favorite voice phrase from a plurality of voice phrases in advance. The PTT processing unit 200 writes the phrase number indicating the selected voice phrase in the call control message at the end of the PTT call, and the stored content of the storage unit 203 is stored in the display unit 20b of the terminal 20. If displayed, the user can set the phrase number corresponding to a favorite audio phrase on the terminal 20 after browsing the contents of the audio phrase.

  The storage unit 203 stores the addresses of the terminals 20 involved in the PTT call. That is, the information stored in the storage unit 203 is for forming part of the information stored in the storage unit 112a (FIG. 1) of the member list management unit 112 described above. For example, when participants who are a plurality of users form a group and perform a PTT call between the terminals 20, the terminal 20 of the user who is the organizer of the group will receive this group prior to the PTT call. A list of terminals 20 of each user who is a participating member is generated.

  The operation unit 204 includes, for example, a cross cursor key, an alphanumeric key for inputting numbers and characters, a key for specifying a function, and the like, and a key for a user of the terminal 20 to input various information. Etc.

  The speaker 206 emits a call voice indicated by voice data from another terminal received from the media server 12 to the user during a PTT call, for example.

  The microphone 207 is used for inputting a call voice made by a user in a PTT call, for example.

  The imaging unit 208 and the image processing unit 209 generate image data for displaying, for example, a captured image by a user or the like during a PTT call on the display unit 20b of the partner terminal 20, and the partner terminal through the wireless transmission / reception unit 201. 20 is transmitted. Specifically, the imaging unit 208 is an imaging element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor).

The call control message is described according to the SIP or the like described above, and includes, for example, a start line, a header part, and a body part.

  In particular, in the case of a call control message transmitted to the call management server 10 from the terminal 20 having the utterance right in order to request the release of the utterance right in the PTT call, a request to release the utterance right (ie, PTT) The first request, which is a request for terminating the call, is described, the address of the source and destination of the call control message are described in the header portion, and the voice data stored in the database 13 in the body portion The phrase number (second request) indicating the audio phrase corresponding to is described. In the example shown in the drawing, a phrase number “2” corresponding to the voice phrase is described in the body portion, and this indicates, for example, “female voice“ please ””.

  In the terminal 20 of this embodiment, the user can select in advance through the operation unit 204 or the like whether or not the phrase number of the voice phrase is automatically given to the body part of the call control message. As described above, when the user can set a favorite voice phrase from a plurality of voice phrases, the PTT processing unit 200 sets a phrase number indicating the selected voice phrase at the end of the PTT call. It is to be described in the body part. On the other hand, when the user is set not to perform the setting, the PTT processing unit 200 generates a call control message in which the phrase number of the voice phrase is not described in the body part at the end of the PTT call. Is. As will be described later, in this embodiment, even if the user has not set the phrase number of the voice phrase, at least based on the request to release the right to speak described in the start line of the call control message, Opening is what is performed. For example, when the relationship between users is such that a PTT call between the terminals 20 can be smoothly executed without giving a voice phrase such as “Please”, the setting is made so that this voice phrase is not given. , Call time can be shortened.

  Next, the database 13 of this embodiment illustrated in FIG. 3B will be described. This database 13 is connected to the call management server 10, and the voice data for notifying the release of the utterance right to be transmitted to the other terminal 20 from the terminal 20 having the utterance right in the PTT call by using a voice phrase, Stored in association with the model number indicating the voice phrase. In the example shown in the figure, a plurality of numbers (type information indicating the type of a voice phrase) are assigned to a plurality of standard voice data. For example, “male voice“ please ”” corresponding to the number “1” means voice data corresponding to the voice phrase “please” by a male. For example, “A-chan“ please ”” corresponding to the number “3” means voice data corresponding to the utterance of the voice phrase “please” by the character (A-chan) of the television animation. In the present embodiment, these voice data are associated with numbers, and for example, a table generated in advance by the call management server 10 is stored in the database 13.

  Furthermore, the member list 112b stored in the storage unit 112a of the member list management unit 112 of the present embodiment illustrated in FIG. 4 includes the name of the owner of the terminal with respect to the telephone number indicating the information specifying the terminal 20. Information indicating the state of involvement of the terminal 20 in the PTT call and information indicating the presence / absence of the utterance right of the terminal 20 in the PTT call are configured and stored in association with each other. As described above, for example, when a plurality of users form a group and perform a PTT call between the terminals 20, the organizer of the group invites members who participate in this group prior to the PTT call. A list of each desired user is selected and generated from a telephone directory or the like. The member list 112b of the present embodiment is generated based on the list received from the terminal 20 of the user who is the organizer immediately before the PTT call. The organizer is registered at the top of the list.

  In the example of the figure, the information for specifying the terminal 20 is the telephone number of the user of the terminal 20, but in short, any information that specifies the terminal 20 may be used.

  Further, in the example of the figure, the information indicating the state of involvement of the member registered in the member list with respect to the PTT call is transmitted from the organizer's terminal 20 to the member registered in the group list selected by the organizer. A notification of invitation to the meeting is issued, and based on the call control message information returned from the terminal 20 that has received the notification of invitation to the meeting to the call management server 10, “participation in meeting” described later is performed. ”,“ Non-participation ”, and“ Stand-by ”. From the example in the figure, Hanako and Ryota responded as “participation” to the invitation of the meeting, “Ichiro” responded as “non-participation”, and “Kyoko” did not respond I know that there is.

  Further, in the example of the figure, “Hanako” is a member who can acquire the right to speak at the present time and can speak, and “1” is associated as the speaking right occupation flag, for example. On the other hand, for example, a flag “0” is associated with other members who have not acquired the right to speak.

  As will be described later, the member list 112b of the present embodiment is broadcast to each terminal 20 and a part thereof (for example, information corresponding to “name” and “state” in FIG. 4) is a meeting participating member. Are displayed so as to be viewable in the same display form.

  Each configuration of the terminal 20 described above is a configuration necessary for realizing the present invention, and a basic configuration as a call management server and other configurations necessary for additional functions are provided as necessary. It shall be.

  A call management operation by the call management server 10 having the above-described configuration will be described with reference to FIGS.

  FIG. 6 is a flowchart illustrating an example of a processing procedure of the call management server 10 in the PTT call according to the present embodiment. Hereinafter, the voice data for notifying the release of the right to speak in the PTT call is referred to as “additional voice data” in the sense of the voice added to the voice related to the PTT call, and corresponds to the content of the PTT call itself. The audio data is simply referred to as “audio data”.

  FIG. 5 is a sequence diagram showing a flow of information transmission / reception in a time series in the call management system 1 for performing a PTT call according to the present embodiment. In the example of FIG. 5, for example, a group meeting is assumed when three users form one group and perform a PTT call between the three terminals 21, 22, and 23. In the call management system 1 of the present embodiment, information such as a call control message, a response message, voice data, and additional voice data is transmitted and received between the call management server 10 and the terminals 21, 22, and 23 as follows. .

  First, when the user of the terminal 21 presses the PTT button 20a, a call control message requesting acquisition of the right to speak is transmitted from the terminal 21 to the call management server 10. The call management server 10 analyzes the call control message, and transmits a response message to each of the terminals 21, 22, and 23 based on the analysis result and the occupancy status of the utterance right in the member list 112b. Specifically, the call management server 10 is only in the case where the utterance right occupation flags in the member list 112b are all “0”, that is, in a state where none of the meeting participating members has acquired the right to speak. By setting the utterance right occupation flag of the terminal 21 (hereinafter referred to as “MS1”) to “1”, the utterance right is assigned to the MS1, and the terminal 22 (hereinafter referred to as “MS2”) and the terminal 23 (hereinafter referred to as “MS1”). A response message to the effect that MS1 has the right to speak is transmitted. Thereby, for example, an icon indicating that the user of MS1 is a speaker is displayed on the display unit 20b of MS1, MS2, and MS3.

  The voice data corresponding to the content of the user's talk of MS1 is transmitted to MS2 and MS3 via the call management server 10. Thereby, the users of MS2 and MS3 can listen to the talk of the user of MS1 through the speaker 206.

  Even if the user of MS1 is in the middle of speaking, that is, when MS1 occupies the right to speak, even if the user of MS2 presses the PTT button 20a, a call control message requesting acquisition of the right to speak is received. It is transmitted from the MS 2 to the call management server 10. However, since the utterance right occupancy flag of MS1 in the member list 112b is already set to “1”, the call management server 10 transmits a response message to the MS2 that the acquisition of the utterance right has failed ( “NG response”). Accordingly, the MS 2 emits a predetermined sound through, for example, the speaker 206 or the buzzer, and notifies the user that the acquisition of the right to speak has failed.

  When the user of MS1 releases the PTT button 20a and finishes talking, a call control message requesting release of the right to speak is transmitted from MS1 to the call management server 10. The call management server 10 analyzes this call control message (FIG. 3A), and adds additional voice data corresponding to the voice phrase indicated by the model number described in the body part from the database 13 (FIG. 3B). The additional voice data is extracted and transmitted to MS2 and MS3, and a response message to the effect of releasing the right to speak is transmitted to MS1 ("OK response"). Thereby, for example, an icon indicating the release of the speaking right is displayed on the display unit 20b of the MS1.

  Thus, the users of MS2 and MS3 listen to the voice phrase (corresponding to the additional voice data) at the end of the PTT call following the voice (corresponding to the voice data) of the PTT call by the user of MS1. . For example, “I am XXX, please” in “I am XXX” is the voice that the user of MS1 utters on the spot, but “Please” is a fixed addition stored in the call management server 10 in advance. It becomes sound.

  Then, in a state where the speech right release icon is displayed, for example, when the MS2 user presses the PTT button 20a, a call control message requesting acquisition of the speech right is sent from the terminal 21 ("MS2"). It is transmitted to the call management server 10. The call management server 10 executes the same process as the process for assigning the utterance right to the MS 1 described above with respect to the MS 2, so that the voice data from the MS 2 passes through the call management server 10 and the MS 1 and the MS 3. Sent to.

  The above description is the flow of information transmission / reception in the call management system 1 that performs the PTT call of the present embodiment.

  Next, PTT call processing in the call management server 10 of this embodiment will be described. FIG. 6 is a flowchart showing the PTT process.

  First, the call management server 10 determines whether or not it has received a call control message (“PTT button press signal”) of a speech right acquisition request accompanying pressing of any of the PTT buttons 20a of MS1, MS2 and MS3 ( S100).

  When it is determined that the call control message for requesting acquisition of the utterance right has been received (S100: YES), the call management server 10 refers to the member list 112b (FIG. 4) stored in the member list management unit 112, and each terminal It is determined whether or not the 20 speaking right occupation flags are all “0” (S101).

  If it is determined that the utterance right occupation flag of any of the terminals 20 is already “1” (S101: NO), the call management server 10 is described in the header part of the call control message of the utterance right acquisition request. A response message indicating that the acquisition of the utterance right has failed is transmitted to the transmission source address (S115), and the process returns to step S100. As a result of the processing from S100 to S115 described above, in the state where the utterance right is already occupied by any terminal 20, the PTT call is not established even if the user of the other terminal 20 presses the PTT button 20a. .

  On the other hand, when it is determined that the utterance right occupancy flags of the respective terminals 20 in the member list 112b are all “0” (S101: YES), the call management server 10 transmits the utterance right acquisition request in the header part of the call control message. An utterance right is assigned to the terminal 20 (for example, MS1) corresponding to the original address (S102). Specifically, the call management server 10 changes the utterance right occupation flag corresponding to MS1 ("Hanako" is a user) in the member list 112b from "0" to "1" (S103). In addition, the call management server 10 resets the timer 111b included in the PoC management unit 111 and then starts measuring time (S104). The timer 111b measures the call time of the MS1. In addition, the call management server 10 transmits a response message indicating that the utterance right has been successfully acquired to the MS 1 (S105), and the MS 1 has the utterance right to the other terminals 20 (MS2 and MS3). The response message is transmitted (S106).

  Thereafter, until the user of MS1 finishes the PTT call, the call management server 10 receives the voice data from MS1, and transmits this voice data to MS2 and MS3 via the media server 12.

  The call management server 10 compares the time measured by the timer 111b with reference to a predetermined upper limit time (for example, 60 seconds) stored in the storage unit 111a of the PoC management unit 111, and whether or not the time has reached the upper limit time. Is determined (S107).

  If it is determined that the time measured by the timer has exceeded the upper limit time (that is, the upper limit time has been reached) (S107: NO), the PoC management unit 111 is a member in order to avoid long-term occupancy of the speaker right. The utterance right occupation flag corresponding to MS1 ("Hanako" is the user) in the list 112b is changed from "1" to "0" (S116). That is, the call management server 10 sets all the utterance right occupation flags in the member list 112b to “0”. Then, the PoC management unit 111 transmits a response message indicating that the speaking right has been released to the other participating members MS1, MS2, and MS3 (S117), and then returns to the processing of step S100 described above.

  On the other hand, in the determination process of S107 described above, when it is determined that the time measured by the timer is equal to or shorter than the upper limit time (S107: YES), the call management server 10 issues a request for releasing the utterance right when the PTT button 20a of the MS1 is pressed. It is determined whether or not a call control message (“PTT button release signal”) has been received (S108). If it is determined that the call control message for the request to release the utterance right has not been received (S108: NO), the call management server 10 returns to the process of step S107 described above. The process is repeated until the determination process of S107 becomes Yes.

  When the user of MS1, that is, the current utterance right occupant, releases the PTT button 20a from the pressed state within the above-described upper limit time to express that the utterance has ended during the PTT call, the call management server 10 A call right release request call control message is received from the terminal 20 used by the current right holder (S108: YES), and this is analyzed (S109).

  When analyzing the call control message for the request to release the utterance right, the call management server 10 determines whether or not the phrase number indicating the voice phrase to be added at the end of the PTT call is described in the body part of the call control message for the request to release the utterance right. Is discriminated (S110).

  When it is determined that the phrase number indicating the voice phrase to be added at the end of the PTT call is described (S110: YES), the call management server 10 adds the additional voice data corresponding to the phrase number stored in the database 13 Is extracted and read (S111).

  Then, the call management server 10 transmits the read additional audio data to the MS2 and MS3 used by other members via the media server 12 (S112), and proceeds to the process of S113.

  On the other hand, in the determination process of S110 described above, when it is determined that the additional voice phrase number is not described in the header part of the message (S110: NO), the process proceeds to S113.

  When the above-described processing of S112 or S110 ends, the member list management unit 112 changes the utterance right occupation flag corresponding to MS1 (“Hanako” is the user) in the member list 112b from “1” to “0” ( S113). Further, the call management server 10 transmits a response message (“OK response”) to the effect that the right to speak is granted to the MS 1 (S114). And it returns to the process of S110 mentioned above. Thereafter, until any user starts a PTT call, voice data is not transmitted / received between the MS1, MS2, and MS3 via the media server 12. The processing contents of the call management server 10 when performing a PTT call in the call management system 1 are as described above.

  Next, the operation of the terminal 20 when performing a PTT call in the call management system 1 will be described. Here, since a plurality of users form a group and perform a PTT call between the terminals 20, the terminal 20 of the user who is the organizer of the group (for example, “Taro”), prior to the PTT call, It is assumed that a list of terminals 20 of each user who is a member participating in this group is generated and transmitted to the call management server 10.

  In the example of FIG. 8A, the list is displayed on the display unit 20 b of the terminal 20. In the example in the figure, five members ("Taro", "Ichiro", "Hanako", "Ryota", "Kyoko") including the organizer are selected as members of the group, but they actually participate in the PTT call. There are three people. As described above, the call management server 10 uses the contents of the call control message transmitted from the terminals 20 of “ICHIRO”, “HANAKO”, “Ryota”, and “Kyoko” that are initially targeted for the “Taro” call. In response, information indicating the state of each terminal 20 in the member list 112b (“participation”, “non-participation”, “standby”) is generated. Specifically, the terminal 20 that has transmitted a call control message including information indicating that it is involved in a PTT call to the call management server 10 is in a “participating” state, and transmits a call control message that includes information indicating that it is not involved in a PTT call. The terminal 20 that has transmitted to the call management server 10 is in a “non-participation” state, and the terminal 20 that has not transmitted a call control message to the call management server 10 is in a “standby” state. The call management server 10 transmits the member list 112b to the terminal 20 and displays it on the display unit 20b of the terminal 20.

  As illustrated in FIG. 8B, when the organizer performs a predetermined operation through the PTT button 20a, the operation unit 204, or the like in order to start a PTT call in the above state, the characters indicating three participants respectively. Alternatively, a screen including an icon or the like indicating which of the three terminals 20 currently occupies the right to speak is displayed on the display unit 20b of each terminal 20.

  FIG. 7 is a flowchart showing terminal operation processing in a PTT call. First, the terminal 20 determines whether or not an icon indicating that the right to speak has been released is displayed (S200). This process is equivalent to a process for determining whether or not the terminal 20 has received a response message from the call management server 10 indicating that the right to speak has been released.

  When it is determined that the speaking right is released and the speaking right is not occupied by any of the members, that is, an icon indicating that the speaking right is in a free state is displayed (S200: YES), the terminal 20 It is determined whether or not the PTT button 20a has been pressed by any one of the members, that is, whether or not the right to speak has been requested (S201).

  If it is determined that the user has pressed the PTT button 20a (S201: YES), the terminal 20 on which the PTT button has been pressed generates a call control message for requesting acquisition of the utterance right and transmits this to the call management server 10. (S202).

  Next, the terminal 20 has not received a response message to the call control message of the utterance right acquisition request from the call management server 10, or has received either a response message of success or failure in acquiring the utterance right. Discriminate (S203, S208). If it is determined that the response message has not been received (S203: NO, S208: NO), the terminal 20 returns to the process of step S203. And it repeats until the process result of S203 becomes Yes.

  On the other hand, when the terminal 20 determines that the response message indicating that the acquisition of the right to speak has failed is received from the call management server 10 (S203: NO, S208: YES), the terminal 20 passes through the speaker 206, the buzzer, or the like. A predetermined sound is emitted to notify the user that the acquisition of the right to speak has failed (S209), and the process returns to step S200. And it repeats until the discrimination | determination process result of S200 becomes Yes.

  Then, in the above-described processing of step S203, when it is determined that the control unit 200 ′ of the terminal 20 requesting the right to speak has received a response message indicating that the right to speak has been successfully acquired from the call management server 10 (S203: YES). The terminal 20 displays an icon such as “busy” on the display unit 20b in the vicinity of the character indicating the user who is the requester of the right to speak as shown in FIG. S204). This display is based on the response message indicating the acquisition of the utterance right received from the call management server 10.

  The terminal 20 transmits the voice data of the PTT call by the user to the call management server 10 (S205). As described above, this audio data is simultaneously transmitted to the terminal 20 used by other participating members via the media server 12.

  As described above, the call management server 10 measures the time of the PTT call by the timer 111b started after acquiring the right to speak. When the time measured by the timer 111b exceeds an upper limit time (for example, 60 seconds), the call management server 10 transmits a response message indicating that the utterance right occupation time has been exceeded to the terminal 20 occupying the right to speak. ing. Therefore, the terminal 20 occupying the right to speak determines whether or not this response message has been received (S206).

  When it is determined that the terminal 20 that occupies the right to speak has received from the call management server 10 a response message indicating that the utterance right occupied time has been exceeded (S206: YES), the call management server 10 determines the utterance right occupation flag of the member list 112b. Are all set to “0”, and the relay of the voice data from the terminal 20 is ended (S207).

  On the other hand, when it is determined that the terminal 20 occupying the right to speak has not received a response message from the call management server 10 indicating that the utterance right occupied time has been exceeded (S206: NO), the terminal 20 is pressed by the user. It is determined whether or not the PTT button 20a that has been opened is released (S210). When it is determined that the PTT button 20a is not opened (S210: NO), the process returns to the above-described step S205. And it repeats until the determination result of step S203 becomes Yes.

  If it is determined that the PTT button 20a has been released (S210: YES), the voice data from the terminal 20 is set by the call management server 10 to have all the speech right occupation flags in the member list 112b set to “0”. Then, the relay of the voice data from the terminal 20 is terminated, and the additional voice data is simultaneously transmitted to the terminals 20 used by other participating members.

  The above is the processing content of the terminal 20 used by the participating members when performing a PTT call.

  As described above, the call management server 10 according to the present embodiment transmits a call control message for requesting the release of the speaking right together with the call control message for requesting the release of the speaking right from the terminal 20 that occupies the right to speak. Upon receiving, the terminal 20 releases the utterance right of the terminal 20 to the other terminal 20 based on the call control message of the utterance right release request, and to the other terminal 20 based on the call control message of the utterance right release notification request. Then, the additional voice data of the voice phrase indicating that the utterance right is released is transmitted. That is, the additional audio data is automatically transmitted to the other terminal 20. Accordingly, the user of the other terminal surely listens to the voice phrase (for example, “Please”) at the end of the PTT call following the voice (for example, “XX” is) ”related to the content of the PTT call. It will be. Therefore, the members participating in the meeting can reliably recognize the end of the other party's talk even if they cannot see each other. Also, the user does not have to follow an artificial arrangement of saying “please” or “over” at the end of his / her call. Therefore, it is possible to efficiently and reliably notify each user of the release of the right to speak between the plurality of terminals 20 in the PTT call.

  In particular, the voice communication unit 121 in the call management server 10 of the present embodiment has both a function of relaying additional voice data and a function of relaying voice data related to the contents of a PTT call. Both the audio data and the audio data are transmitted to the terminal 20 via the audio communication unit 121. Therefore, for example, the timing of the utterance of “Please” in response to “I am XXX” is natural and good.

  Further, in the present embodiment, the terminal 20 that occupies the utterance right can select whether or not to transmit the call control message of the utterance right release notification request, and the call management server 10 performs this step S110 in the above-described step S110. It is determined whether or not a call control message for requesting release of the right to speak is received from the terminal 20, and when it is determined that it has been received, other members participating in the meeting simultaneously transmit additional voice data to the terminal 20 used. To do. Thus, the call management server 10 can efficiently determine whether or not the other terminal 20 utters a voice phrase that notifies the release of the utterance right through analysis of the call control message from the terminal 20 having the utterance right.

  Furthermore, the call management server 10 of the present embodiment includes a database 13 that stores a plurality of additional voice data corresponding to a plurality of types of voice phrases, and a type for identifying a voice phrase included in the call control message from the database 13. Additional audio data corresponding to the information is extracted. As a result, if the call control message includes type information, the call management server 10 notifies the release of the right to speak by extracting data corresponding to this type from a plurality of types of additional voice data prepared in advance. Can be uttered efficiently by the other terminal 20.

  In particular, in the present embodiment, the additional voice data indicates a standard voice phrase, and the type information thereof is a phrase number. For example, the load on the database 13 is reduced as the number of voice phrase pattern types is limited to a small number. Is done.

  In the embodiment described above, a phrase number indicating a standard voice phrase is embedded in the body part of the call control message requesting the release of the right to speak, but the present invention is not limited to this. For example, the terminal 20 may embed the additional voice data itself in the body part of the call control message and transmit it to the call management server 10.

  In order to achieve this, the terminal 20 used by the meeting participants downloads additional voice data from, for example, a function for generating additional voice data or an external server (a server outside the call management system 1). It is necessary to have a function for doing so. On the other hand, in this case, the database 13 described above is not an essential configuration for the call management server 10.

  As described above, PoC service users can use a voice phrase that suits their preference in a PTT call, and therefore an increase in the number of users of this PTT call can be expected. Further, the equipment cost of the call management server 10 can be reduced by the amount that does not require the database 13.

  Further, for example, the additional voice data stored in the database 13 of the call management server 10 may be provided from an external server (a server outside the call management system 1) or the like. Here, it is assumed that the user has previously purchased the right to use the additional audio data from a company that manages the external server, for example.

  In this case, the additional audio data is stored in the database 13 in association with information for identifying the user or the terminal 20 thereof. When a user first accesses the call management server 10 from the terminal 20 during a PTT call, or a meeting member has accessed the call management server 10 from the terminal 20 in use in order to change a predetermined setting related to the PTT call. At this time, it is possible to select which of the plurality of purchased additional audio data is to be used. The call management server 10 searches for additional voice data purchased by the user based on the user transmitted from the terminal 20 or the identification information of the terminal 20. The user can select additional audio data to be used (data indicating an audio phrase designated by the user of the terminal) from the plurality of additional audio data searched. When purchasing the additional audio data, for example, the user can be charged on a flat rate system or a pay-as-you-go system.

  As described above, since the additional voice data in the database 13 is provided from an external server, the types can be abundant, so that the user can use a voice phrase that suits his / her preference in the PTT call. As a result, an increase in the number of users of the PTT call can be expected.

  The above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and equivalents thereof are also included in the present invention.

  In the above-described embodiment, the voice communication unit 121 (FIG. 1) of the media server 12 in the call management server 10 corresponds to the content of the PTT call between the plurality of terminals 20 in addition to the function of relaying the additional voice data. However, the present invention is not limited to this. For example, the voice communication unit 121 may relay only the additional voice data and does not relay the voice data. In this case, the voice data is directly transmitted as a voice IP packet from the terminal 20 having the right to speak to the other terminal 20 in accordance with, for example, the well-known VoIP (Voice over IP) method. In this way, if the data processing load is reduced by the amount not to relay the voice data, the equipment cost of the media server 12 is reduced.

  In the above-described embodiment, the media server 12 in the call management server 10 includes the image communication unit 122 and the text communication unit 123, but is not limited thereto. For example, the media server 12 may not include the image communication unit 122 and the text communication unit 123. In this case, the equipment cost of the media server 12 is reduced by the amount that the image communication unit 122 and the text communication unit 123 are not provided.

  In the above-described embodiment, the call management server 10 is configured by being divided into two servers (PoC server 11 and media server 12) and one database 13. However, the present invention is not limited to this. The call management server 10 may be an information processing apparatus in which these are integrated, for example. In short, the call management server 10 has a known configuration for fulfilling a known function of establishing a session of a PTT call and fulfills a function of transmitting additional voice data to each terminal 20 at the end of the PTT call. Any information device may be used as long as it has a configuration for the above.

  In the example of FIG. 1 described above, the number of terminals 20 managed by the call management server 10 is three or more. However, the number of terminals 20 is not limited to this, and may be two, for example. In this case, a PTT call based on the PoC service is performed between the two terminals 20.

  Further, in step S110 in the processing contents of the call management server shown in FIG. 6 described above, when there is no information (phrase number) related to the voice phrase in the body part of the call control message, the voice phrase is not given. It is not limited. When there is no information in the body part, for example, a predetermined voice phrase may be given uniformly. Thereby, the notification of the release of the right to speak is uniformly performed.

  Further, in step S110 in the processing contents of the call management server shown in FIG. 6 described above, it is determined whether or not there is a phrase number indicating a voice phrase in the body part of the call control message. However, the present invention is not limited to this. It is not something. For example, the body part may be provided with information indicating whether or not to add a voice phrase at the end of a PTT call and information for specifying a voice phrase when it is added. In this case, first, it is determined whether or not a voice phrase is to be assigned. If it is determined that a voice phrase is to be given, a voice phrase is further specified.

  In the above-described embodiment, the call control message includes both information requesting release of the right to speak and information requesting release notification in one message. However, the present invention is not limited to this. Is not to be done. For example, two call control messages corresponding to the information of the two requests may be generated.

  In the above-described embodiment, each terminal 20 includes the PTT button 20a. However, the present invention is not limited to this. In short, any means may be used as long as it is a means for providing a trigger for switching between the call right control request request message and the call right release request call control message output from the PTT processing unit 200. For example, the operation of pressing or releasing the PTT button 20a may be replaced with a predetermined input operation from the operation unit 204. Since the PTT button 20a is not provided, the manufacturing cost of the terminal 20 can be reduced.

  In the above-described embodiment, the call management server 10 transmits the additional voice data as a voice IP packet to the terminal 20 via the media server 12, while the terminal 20 utters the additional voice data from the speaker 206. For this reason, a voice phrase is uttered through the speaker 206. However, the present invention is not limited to this. For example, the call management server 10 directly transmits a signal that triggers a predetermined voice phrase from the speaker 206 of the terminal 20 without using the media server 12. You may transmit to. In this case, the terminal 20 needs to include a storage unit that stores additional audio data corresponding to the audio phrase in order to cause the speaker 206 to utter the predetermined audio phrase based on the trigger signal. is there. On the other hand, the call management server 10 reduces the facility cost by the amount that the media server 12 does not need to be provided.

  In addition, the program can be applied to an existing call management server that does not have these functions as well as the call management server that has functions for realizing the present invention, such as the call management server 10 described above. By doing so, it can also function as a call management server according to the present invention. In this case, at least a program that executes each process of the call management server 10 described above is applied to a call management server that connects a terminal such as a mobile phone and relays the call, and the call management server A computer (such as a CPU) that controls the computer can execute the program, thereby functioning as a call management device according to the present invention.

  The application method of such a program is arbitrary. For example, it can be applied to an arbitrary device by providing it via a communication medium such as the Internet, and a predetermined recording medium (for example, a memory card, a CD-ROM, a DVD, etc.) It can also be applied by storing and distributing the program in ().
