Description

  The present invention relates to a communication terminal device, a communication system, and a communication method used in a communication system in which a plurality of communication devices communicate with each other.

  In recent years, modes of communication by communication terminals such as mobile phones have been diversified, and in addition to conventional voice calls by circuit switching, new modes of communication such as packet communication using an IP (Internet Protocol) network are being performed. . For example, there is “chat mail” in which a conversation is performed by exchanging characters between communication terminals in real time (see Patent Document 1). Chat mail is one of communication modes called “group communication” in which a group is formed between members registered in advance and data such as characters is communicated in real time within the group.

One group communication that has recently attracted attention is called PoC (Push to Talk over Cellular). PoC is a technology that enables a plurality of communication terminals forming a group to perform real-time communication. In PoC, data can be transmitted all at once from one communication terminal on the transmission side to a plurality of communication terminals on the reception side.
In PoC, a communication terminal holder who intends to start group communication transmits a group communication start notification to another communication terminal, and the communication terminal that has received the communication start notification holds the source communication terminal included in the communication start notification. The person information and the number of communication start notifications transmitted are displayed, and the communication terminal holder is made to judge whether or not to participate in group communication using this as a judgment material.

As described above, in the PoC in the related related technology, the communication start notification transmission source information (name, telephone number, Email address, etc.) and the number of communication participation request transmissions (group communication member) are transmitted from the group communication start notification. For example, a user who has received a communication start notification participates in group communication, and then notices that there is a partner who does not want to speak in the group communication participants. There is a disadvantage that it cannot be prevented.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a diagram illustrating an example of a configuration of a communication system according to the present embodiment.
The communication system according to the present invention includes, for example, three or more communication terminals (100-1, 100-2, 100-3...) And a communication server device 200 as shown in FIG.

  The communication terminal 100-i (i represents a natural number) is a wireless communication terminal such as a mobile phone, and is connected to the communication network 300 via base stations (300-1, 300-2, 300-3,...). The In addition, the communication terminal 100-i performs data communication according to the control of the communication server device 200 connected to the communication network 300. In the present embodiment, as an example, group communication by PoC (Push to Talk over Cellular) is performed.

  The data transmitted in this data communication includes, for example, data such as voice of calls, images, and characters.

  In this communication system, one communication terminal permitted to transmit by the communication server device 200 among a plurality of communication terminals (100-1, 100-2, 100-3...) Transmits data to other communication terminals. Is possible. Communication terminal 100-i desiring data transmission transmits a communication permission request to communication server apparatus 200.

  Moreover, the communication terminal 100-i has a display unit that can display various types of information provided from the communication server device 200, as will be described later. When the communication terminal 100-i requests the above-described communication permission from the communication server device 200, information regarding the communication terminal currently waiting for communication permission in the communication system is transmitted from the communication server device 200 to the communication terminal 100-i. The The communication terminal 100-i receives information from the communication server device 200 and displays it on the display unit.

The communication server device 200 is a device that manages PoC group communication by three or more communication terminals (100-1, 100-2, 100-3,...).
Upon receiving a PoC group call start notification from one communication terminal, communication server apparatus 200 calls the other party's communication terminal in response to the request and establishes a communication session.

  After establishing the communication session, the communication server device 200 relays data transmitted from one communication terminal to a plurality of communication terminals. In other words, data transmitted from the transmitting communication terminal to the receiving communication terminal is temporarily received and transferred to the receiving communication terminal.

  Further, the communication server device 200 receives the transmission permission request of each communication terminal 100-i, lists the transmission permission request of each terminal in the order received, and puts it on the list every time transmission of the terminal that is currently transmitting ends. The next terminal is allowed to transmit in sequence.

Next, the communication terminal 100-i of this embodiment will be described.
FIG. 2 is a diagram illustrating an example of the configuration of the communication terminal 100-i.
For example, as shown in FIG. 2, the communication terminal 100-i includes an antenna 1, a communication unit 2, a key input unit 3, a voice processing unit 4, a display unit 5, a storage unit 6, and a control unit 7. Have

The communication unit 2 performs processing related to wireless communication with the base stations (300-1, 300-2,...) Of the communication network 300. For example, transmission data supplied from the control unit 7 to be described later is subjected to predetermined modulation processing to be converted into a radio signal and transmitted from the antenna 1. Further, the radio signal from the base station received by the antenna 1 is subjected to a predetermined demodulation process to be converted into reception data, and output to the control unit 7.
The communication terminal 100-i communicates with the communication server device 200 and other terminals connected to the communication network 300 via the communication unit 2.

  The key input unit 3 is a device for inputting user instructions to the communication terminal. For example, it has keys with various functions such as numeric keys, character keys, direction keys, and decision keys. When these keys are operated by the user, the operation content is converted into electrical signals and controlled. Output to unit 7.

The key input unit 3 is provided with a transmission key (talk key) for switching between transmission and reception in PoC. When the user operates this transmission key, a transmission permission request for the communication server device 200 is transmitted from the communication unit 2.
When the transmission key is pressed, the communication server device determines whether another communication terminal is speaking or not, and if there is no communication terminal that is speaking, it makes a message to the communication terminal that pressed the transmission key. Give the right. While the transmission key is pressed, this right to speak is continuously given and the transmission state is established, and the voice input from the microphone is simultaneously transmitted to other communication terminals via the communication server device. However, when the transmission key is released (the transmission key is stopped), the right to speak is lost and the input voice is not transmitted. Instead, the speaker receives a message from another communication terminal via the communication server device, and the speaker. It will be in the state which outputs to

  The audio processing unit 4 processes an audio signal input / output through a speaker or a microphone. That is, the audio signal input from the microphone is subjected to signal processing such as amplification, analog-digital conversion, encoding, and the like, converted into digital audio data, and output to the control unit 7. In addition, the audio data supplied from the control unit 7 is subjected to signal processing such as decoding, digital-analog conversion, amplification, and the like, converted into an analog audio signal, and output to the speaker.

  The display unit 5 is configured by using a display device such as a liquid crystal display panel or an organic EL panel, for example, and displays information corresponding to data supplied from the control unit 7. For example, the destination telephone number at the time of outgoing call, the telephone number of the other party at the time of incoming call, the contents of the received mail and the outgoing mail, the standby screen, date, time, remaining battery level, etc. are displayed.

  The display unit 5 displays various information and notifications sent from the communication server device 200 during group communication by PoC. For example, a communication start notification screen described later, a list of communication terminals participating in group communication, information on communication terminals waiting for transmission permission, requests and messages issued from one communication terminal to other terminals, this request And the response of another communication terminal to the message or the like is displayed.

  Note that the display unit 5 includes a speaker, a vibrator, or the like not shown in FIG. 2, and may notify various information by voice instead of characters, for example, or notify reception of communication start notification by vibration.

  The storage unit 6 stores various data used in the processing of the control unit 7 and data of processing results of the control unit 7. For example, identification of the computer program of the control unit 7, constant data used for the processing, variable data that needs to be temporarily stored in the process, telephone number, e-mail address, and other network services such as outgoing calls and e-mail transmission An address book in which a plurality of address information as IDs are collected for each destination is stored.

The control unit 7 performs various processes related to the overall operation of the communication terminal.
For example, as processing related to group communication, voice input / output in the voice processing unit 4 and input / display of character data from the key input unit 3 so that voice communication and data communication in accordance with a predetermined protocol in PoC are appropriately performed. The display of information in the unit 5 and the transmission / reception of data in the communication unit 2 are controlled.

  In addition, the control unit 7 includes a computer that executes processing based on a program (operating system, application, or the like) stored in the storage unit 6, for example, and executes the above-described processing according to the program.

When the user wants to start a group call, the control unit 7 causes the communication unit 2 to transmit a communication start notification to the communication server device 200.
When a request to start group communication is sent to the communication server device, the communication server device provides a site for controlling group communication on the own device or another server device. Here, the communication start notification is a notification that such a site has been established, and is necessary for participation in group communication such as an address on the communication network 300 of the site and a login ID for logging in to the site. This is transmitted based on the member address information described in the previous management table.
Further, the control unit 7 performs a process of transmitting data from the communication unit 2 after the PoC group communication is started. For example, when a PoC transmission key is pressed in the key input unit 3, a transmission permission request for the communication server device 200 is transmitted from the communication unit 2.
In addition, after the PoC group communication starts, the control unit 7 performs a process of receiving data in the communication unit 2. For example, after transmitting the above-mentioned transmission permission request from the communication unit 2, the communication unit 2 receives transmission reservation list information transmitted from the communication server apparatus 200 (information on communication terminals waiting for transmission permission in the communication system). To do.

  In addition, the control unit 7 causes the display unit 5 to display various types of information regarding PoC group communication.

Next, an operation example during group communication of the communication terminals 100-1 to 100-3 according to the present embodiment in the communication system illustrated in FIG. 1 will be described.
FIG. 3 is a sequence diagram when the communication terminals 100-1 to 100-3 according to the present embodiment perform group communication.
As shown in FIG. 3, in this embodiment, the communication start terminal 100-1 side that transmits the communication start notification performs the process, and the participating member communication terminals 100-2 and 100-3 side that received the communication start notification Since there are steps to perform processing, an operation example of the communication terminal will be described below for each step.
Step ST1:
This step is an operation example of the communication start terminal 100-1 possessed by the organizer user X who intends to start group communication.
For example, when the user X of the communication start terminal 100-1 starts PoC application software (hereinafter abbreviated as a PoC application) by operating the key input unit 3, processing for group communication is started.

The control unit 7 displays a personal information notification setting screen as shown in FIG. 4 on the display unit 5, and determines whether or not to notify the personal information of the own terminal 100-1 to other terminals at the time of notification of the start of communication of the group call. The user X is set via the key input unit 3.
Here, the personal information refers to a name, a telephone number, a mail address, and the like that can identify each user or terminal. The personal information may include user face photo image data, an address, and the like. In that case, elements other than the above-mentioned name, phone number, and mail address such as face photo image data and address can be set on the personal information notification setting screen.

  Next, the user X refers to the address book on the PoC application, and, for example, the communication terminal 100-2 (user A), 100-3 as a partner who wants to perform group communication via the key input unit 3 or the like. Designate identification information (address information) such as a telephone number of (User B). User A and user B are hereinafter referred to as participating members.

  The control unit 7 specified as the partner of the group communication calls the communication server device 200, which is a server on the communication network 300 such as the Internet, to the communication unit 2 via the base station 300-1 according to the processing routine of the PoC application. The communication server device 200 is notified of address information such as its own telephone number for communication including the start notification of group communication and the transmission of its own personal information that can be notified as determined above. Start on.

When communication server apparatus 200 receives communication start request notification from PoC from communication terminal 100-1, which is a communication start terminal, and starts communication with communication terminal 100-1, communication participation in communication terminal 100-1 Request for member address information. The communication terminal 100-1 transmits the address information of the designated communication participating member, and the communication server apparatus 200 receives this. From the address information regarding this member with the address information of the communication start terminal 100-1, the communication server 200 creates a management table concerning group communication as a participant state list, send and receive mutual data communication terminal their respective And a site for controlling group communication such as granting a speaking right are provided on the communication server device 200. Note that the above-described site for group communication control may be provided on a server other than the communication server device 200.

  When the management table is also stored in the storage unit 6 of the communication start terminal 100-1, the communication server device 200 transmits a communication start notification and a member list to all members of the group communication.

  Thereafter, the communication server device 200 monitors the communication start notification and the response from the member who has transmitted the member list, and if there is a response from these members, notifies the communication start terminal 100-1 each time, depending on the response content. The participation status of the participation status list in the storage unit 6 and the communication server device 200 is set to participation (IN) or non-participation (OUT) (depending on the presence or absence of a participation flag).

  The communication start notification may be transmitted from the communication server device 200 to the communication terminals 100-2 and 100-3 of the other members, but the communication start terminal 100-1 addresses each member address. You may send it. In addition, responses from members, messages in group communication, and the like are managed via the communication server device 200 and delivered to the communication start terminal 100-1.

Step ST2:
In this step, a communication terminal that has received the communication start notification transmitted in step ST1 and the personal information of the communication start terminal 100-1, for example, processing 100-2 of the user A will be described.

First, the communication unit 2 receives from the communication network 300 a communication start notification of PoC communication from the communication server device 200 addressed to its own terminal 100-2 (via the communication start terminal 100-1).
Note that in the case of a system such as this embodiment in which a communication start notification is sent from another communication terminal device via the communication server device 200, the sender of the received call is referred to, or the content of the received call is communicated. It is determined whether or not parameters used for logging in to the server apparatus 200 are described, whether the notification is a communication start notification according to the present invention by various methods, such as an incoming call for the purpose of a voice call by normal circuit switching, You only have to determine whether you are receiving mail.

  Next, the control unit 7 reads and activates the PoC application stored in the storage unit 6 in response to the communication start notification received by the communication unit 2, and starts PoC-related processing.

The control unit 7 causes the display unit 5 to display the communication start request notification received by the communication unit 2.
FIG. 5 is a diagram illustrating an example of a communication start request notification screen.
As shown in FIG. 5, on the communication start request notification screen, for example, an icon for setting notification of personal information (50 2 in FIG. 5) or an icon for displaying details (personal information) of other participating members (FIG. 5). 5 1 ) and icons (503 and 504 in FIG. 5) for determining whether or not to participate in group communication are further displayed, and the respective icons can be selected by input from the key input unit 3 or the like. .

The user input by the key input unit 3 or the like, when the icon 50 2 to notify setting personal information shown in FIG. 5 is selected, the control unit 7, the personal information notification setting screen shown in FIG. 4 on the display unit 5 , And allows the user A to set whether or not to notify other communication terminals of each element of personal information (name, telephone number, mail address, etc.).
Here, the personal information setting screen shown in FIG. 4 is displayed on the display unit 5 by the terminal 100-2 that has received the communication start request notification and the communication start terminal 100-1 that has transmitted the communication start request notification. However, the screen may not be the same as long as the screen asks whether each element of personal information can be notified.

  Next, the control unit 7 causes the communication unit 2 to transmit the personal information notification enable / disable information determined on the personal information notification setting screen to the communication start terminal 100-1 through the communication server device 200. The information to be transmitted here may be only personal information notification availability information, or may be transmitted with personal information added to the notification availability information. Further, when it is not desired to make the name known to other participating members, the notification permission name may be transmitted together with the personal information notification permission / inhibition information and the personal information. The notification permission name is a name that can be freely determined by the user using the key input unit 3, such as a nickname. The notification permission name may be determined in advance by the user and stored in the storage unit 6, or may be determined when setting whether or not to notify personal information.

In communication start request notification screen shown in FIG. 5, when the icon 50 1 to display the details of participating members is selected by the key input section 3 causes the display unit 5 a participating member details screen shown in FIG. 6 (a) .
At this stage, since the personal information of the participating members (users A and B) has not been displayed yet, the participating member details screen is displayed on the group call organizer's user X as shown in FIG. Is a screen on which only the elements of the personal information that are set to notify other terminals in advance are displayed. FIG. 6A shows an example of the case where the user X is set to be able to notify all of his name, phone number, and mail address.
The reason why the personal information of the participating members is not displayed is that, as will be described later in detail, the personal information notification permission / inhibition information of all the participating members is not yet possessed.

  Further, the disclosure of the personal information may be set for each terminal in advance. In each terminal, when the group communication is not being performed, the personal information setting screen shown in FIG. 4 is called and the personal information is set to be disclosed by the key input unit. When it is received, whether or not to disclose personal information is automatically transmitted based on the preset contents. Thereby, it is not only necessary to set the disclosure of personal information every time, but it is possible to notify at least an early stage of the start of group communication about user information that is not basically refused to disclose personal information.

In addition, when the icons 503 and 504 for determining whether or not to participate in group communication are selected by the key input unit 3 on the communication start notification screen of FIG. 2, when the participation notification is transmitted to the communication terminal that is the transmission start notification, and the non-participation icon 504, the control unit 7 causes the communication unit 2 to transmit the non-participation notification to the communication terminal that is the transmission start notification. The communication with the server device 200 is disconnected.
It should be noted that the icons 503 and 504 for determining whether or not to participate in group communication may be selected in step ST2 in which the personal information of all participating members is not displayed, or for all participating members. It may be in step ST4 to be described later on which personal information is displayed.

  As described above, on the condition that the communication start terminal 100 has received the personal notification availability information transmitted by the communication terminals of all the participating members or that a predetermined time has elapsed since the communication start notification was transmitted. Proceed to ST3.

Step ST3:
This step describes the processing of the communication start terminal 100-1 that has received the personal information notification availability information transmitted from the terminal of each participating member in step ST2.
The control unit 7 causes the communication unit 2 to receive personal information notification availability information.
Here, as an example, personal information propriety information such as name: YES, telephone number: NO, mail address NO is transmitted from user A, and a predetermined time has elapsed since user B transmits a communication start notification. Suppose there was no reaction. Regarding user B, it is treated as NO for all elements as no response. Note that “YES” means that notification is permitted to other communication terminals regarding the element, and “No” means that notification is not permitted.
It should be noted that, here, if there is no transmission of personal information notification availability information even after a predetermined time has passed since the transmission of the group call communication start notification, NO response is given to all elements as “no response”. However, notification of personal information from the terminal may be put on hold until there is a response.

The control unit 7 causes the communication unit 2 to transmit the personal information permitted to be notified to the communication terminal of each participating member in accordance with the personal information notification availability information from each participating member.
At this time, as the personal information to be transmitted, when the personal information is transmitted from the communication terminal of the participating member together with the personal information notification availability information in step ST3, the transmitted personal information may be used. If no personal information has been transmitted, the corresponding personal information stored in the address book information in the storage unit 6 of the communication start terminal 100-1 is used.
If no personal information is transmitted in step ST3 and the corresponding personal information is not stored in the storage unit 6 of the communication start terminal 100-1, the corresponding personal information cannot be transmitted and is not transmitted.

  When the notification permission name is transmitted together with the personal information notification permission / inhibition information, the control unit 7 transmits the element “name” of the personal information to the communication terminal other than the member who transmitted the notification permission name. Regardless of the member's personal information notification availability information, the communication unit 2 is not transmitted, but a notification permission name is transmitted instead.

Step ST4:
In this step, for example, processing of the communication terminal 100-2 that has received the personal information transmitted in step ST3 will be described.
The control unit 7 of the communication terminal 100-2 that has received the personal information stores the personal information in the storage unit 6.
Control unit 7, the input via the input unit of the user A, the communication start request notification screen shown in FIG. 5, when the icon 50 1 to display the details of the participating members is selected is shown in FIG. 6 (b), each A participating member detail screen displaying the member's personal information is displayed on the display unit 5.
FIG. 6B shows a case where the user A is set to be able to notify the name and telephone number, and the user B does not respond.
The user sees the participating member details screen on which the personal information is displayed, and again selects the participation icon 503 or the non-participation icon 504 for determining participation or non-participation on the communication start request notification screen shown in FIG. When the icon 503 is selected, the control unit 7 causes the communication unit 2 to transmit a participation notification to the communication terminal that is the source of the communication start request notification. When the non-participation icon 504 is selected, the control unit 7 2, the non-participation notification is transmitted to the communication terminal that has transmitted the communication start request notification, and the communication with the communication server device 200 is disconnected.

Step ST5:
This step describes the processing of the communication start terminal 100-1 that has received the participation notification or non-participation notification transmitted in step ST4 from each participating communication terminal.
The communication start terminal 100-1 receives a participation notification or non-participation notification from each terminal, and starts a normal PoC process to be described later with the communication terminal that has transmitted the participation notification.

The processing (normal PoC processing) of the communication terminal after starting group communication is as follows.
When the owner of one communication terminal, for example, the communication terminal 100-3 presses a transmission key (Talk key) in the key input unit 3, a request for speech is made from the communication terminal 100-3 to the communication server device 200. If there is another member who is pressing the transmission key, communication server apparatus 200 transmits a rejection signal to communication terminal 100-3. The communication terminal 100-3 receives the rejection signal, sounds an error sound, for example, and notifies the user that speech is impossible.
