Description

  The present invention relates to a group communication control method, a communication terminal, and a communication system 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 members registered in advance form a group and perform data communication such as characters 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, communication by voice, characters, images, or the like can be performed.
JP 2003-174520 A

  A communication terminal such as a mobile phone capable of performing PoC has a software configuration as shown in FIG. That is, as shown in FIG. 5, an OS (Operating System) that controls the entire communication terminal is at the root, and controls basic functions of the communication terminal, such as a voice call function, a mail function, a character input function, and a data folder reference function. Each program and an application manager that operates applications such as a game, GPS, music playback, and group communication operate on the OS.

  Here, when performing group communication in the conventional communication terminal having the above-described configuration, the following disadvantages occur. That is, as shown in FIG. 5, the group communication application operates on the application manager, and the application manager and, for example, the data folder reference function and the character input function, which are basic functions of the communication terminal, operate independently on the OS. Therefore, the group communication application does not know whether data folder reference or character input is being performed during the operation. The group communication application has a timer that monitors the presence / absence of communication and terminates the group communication when there is no communication for a certain period of time. For the above reasons, the character input function is used to transmit text. Even if a data folder is referenced to send image or audio data, the group communication application does not know it, and the group communication ends when a certain time elapses after the timer is activated. There is a disadvantage that it becomes impossible to transmit the text, image and sound data. Termination of the group communication application is performed for the purpose of power saving of communication terminals or freeing of communication traffic, but group communication is also performed when the user has input characters or selected images for a certain period of time. However, there was a disadvantage that it was not easy to use.

Hereinafter, embodiments of the present invention will be described.
<First Embodiment>
FIG. 1 is a diagram illustrating an example of a configuration of a communication system 1000 according to the present embodiment.
The communication system 1000 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 indicates a positive integer) 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,...). Is done. 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 1000, 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. It is possible to send. 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 1000 is transmitted from the communication server device 200 to the communication terminal 100-i. Is done. 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 group communication by three or more communication terminals (100-1, 100-2, 100-3...).
When communication server device 200 receives a group communication start notification from one communication terminal, communication server device 200 calls the other 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. And a camera (imaging device) 8.

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 group communication. 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 to output to.

  Further, the key input unit 3 can input a data creation operation in group communication and a transmission request for the created data in group communication. In other words, a key to perform a character input editor start request, an image pickup unit start request for image pickup, and a data folder reference request is loaned, and a character input or a photographed image attached thereto is selected or referenced Attached data is created to create data. These controls are performed by the control unit 7 described later.

  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. 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 In addition to the response of another communication terminal to a message, a message creation screen for transmission, an imaging camera operation screen, a reference screen for data stored in a data folder that is a storage area in the storage unit 6 in advance indicate. Further, a screen during data transmission is displayed, and conversely, a screen related to pseudo data transmission is not displayed during transmission of pseudo data, which will be described later.

  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 In addition to storing an address book in which a plurality of address information, which are IDs, are collected for each destination, the above-mentioned data folder is provided.

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

  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 after designating a group communication partner.
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. It is transmitted based on the member address information described in the previous management table.

Moreover, the control part 7 performs the process which transmits data from the communication part 2 after group communication starts. 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 group communication starts, the control unit 7 performs a process of receiving data in the communication unit 2. For example, after transmitting the above-described transmission permission request from the communication unit 2, the communication unit 2 receives transmission reservation list information (information relating to a communication terminal waiting for transmission permission in the communication system 1000) transmitted from the communication server device 200. Receive.
In addition, the control unit 7 causes the display unit 5 to display various information related to group communication.
The control unit 7 further includes a timer 71. The operation of the timer 71 will be described in an operation example of the communication terminal 100-i described later.
The camera 8 is an imaging device that captures an image. The camera 8 is activated by a user operation via the key input unit 3 and performs imaging under the control of the control unit 7. The camera 8 can also be activated during group communication, and can capture images during group communication as image data to be transmitted attached to the group communication and directly transmit the captured image data.

Hereinafter, an operation example during group communication by PoC of the communication terminal 100-i (i is a positive integer) of the first embodiment will be described in association with the flowchart shown in FIG.
Step ST1:
When the address book is displayed on the display unit 5 by the key input unit 3 and a partner is selected and a group communication start request is made, the control unit 7 causes the communication unit 2 to perform another communication via the communication server device 200. Group communication with the terminal 100-j (j is a positive integer other than i) is established.
Step ST2:
Communication of data (voice data, character data, image data, etc.) by the communication unit 2, that is, transmission or reception is once completed. The completion of communication means that transmission / reception of voice, text, and image data corresponding to one message in group communication is completed.

Step ST3:
When transmission or reception by the communication unit 2 is completed in step ST2, the control unit 7 starts a timer 71 and counts time.
Step ST4:
The control unit 7 monitors whether or not data communication is newly performed by the communication unit 2 after the timer is started. If it is performed, the process proceeds to step ST7, and if not, the process proceeds to step ST5.

Step ST5:
The control unit 7 monitors the activation of a text editor for character input to create transmission data. If activated, the control unit 7 proceeds to step ST6, and if not activated, the process proceeds to step ST8.
Step ST6:
The control unit 7 monitors whether or not there is a key operation for inputting characters by the text editor activated in step ST5. If there is, the process proceeds to step ST7, and if not, the process proceeds to step ST8.

Step ST7:
When the communication of the data being performed is completed, the control unit 7 resets the timer 71, that is, stops counting up to the present time, returns it to the initial value, and returns to step ST2.
Step ST8:
When the timer 71 counts for a predetermined time, the control unit 7 proceeds to step ST8, and when the count has not yet reached the predetermined time, the control unit 7 returns to step ST4. The predetermined time is, for example, 2 to 3 minutes. For example, a numerical value may be set when the communication terminal 100-i is designed, or may be a numerical value that the user can freely set when waiting for the communication terminal 100-i. .
Step ST9:
The control unit 7 ends the group communication.

  As described above, according to the first embodiment of the communication terminal 100-i according to the present invention, the control unit 7 monitors the activation of the text editor, further monitors the presence or absence of key input, and communication is once completed. The specified time elapses without the editor being started (the timer counts the predetermined time), or the predetermined time elapses without any key input after the editor is activated after communication is completed. Because the group communication is terminated only in any of the cases, the timer 71 counts for a predetermined time and the control unit 7 terminates the group communication even though the user inputs characters for transmission as group communication. Can be avoided.

In the present embodiment, the control unit 7 resets the timer 71 based on activation of the text editor and key input, but the present invention is not limited to this. The communication terminal 100-i according to the present invention may reset the timer 71 based on the occurrence of a predetermined event for creating data to be transmitted, instead of starting the text editor and inputting a key.
The predetermined event is, for example, an operation of opening a case of the communication terminal 100-i (or an operation of changing the communication terminal 100-i to a state where the communication terminal 100-i can be operated or is easy to operate, such as sliding, rotation, etc.) Reference (that is, an operation of selecting image or audio data to be transmitted attached to group communication from the data folder), activation of the camera (imaging device) 8, and the like. In the case of resetting the timer 71 by the occurrence of these predetermined events, in the operation example of FIG. 3, a step for the controller 7 to monitor the presence or absence of the predetermined event is inserted instead of steps ST5 and ST6. If there is an event, the process proceeds to step ST7, and if there is no predetermined event, the process proceeds to step ST8.
The predetermined event is not limited to the example described above.

<Second Embodiment>
In the first embodiment of the present invention, the control unit 7 of the communication terminal 100-i has the timer 71, and the control unit 7 terminates the group communication on condition that the timer 71 has counted for a predetermined time. In the second embodiment, the communication server device 200 has a timer 201, and between the communication terminals performing group communication via the communication server device 200 on the condition that the timer 201 has counted for a predetermined time. The communication server device 200 ends the group communication.
This will be described in detail below.

The communication server device 200 has a timer 201. The timer 201 counts the time from the end of communication with each communication terminal 100-i performing group communication to each communication terminal 100-i.
Since each configuration of the communication system 1000 other than the timer 201 is the same as that of the first embodiment, description thereof is omitted.

Hereinafter, an operation example during group communication in the communication system 1000 according to the second embodiment of the present invention will be described in association with the sequence diagram illustrated in FIG. 4.
The sequence diagram illustrated in FIG. 4 illustrates an operation example of one communication terminal 100-i and the communication server device 200 among the plurality of communication terminals 100 when the plurality of communication terminals perform group communication via the communication server device 200. FIG.

Step ST11:
Group communication among the communication terminal 100-i, the other communication terminal 100, and the communication server device 200 is established as in the first embodiment.
Step ST12:
Data communication between the communication terminal 100-i and the communication server device 200 is once completed (similar to the first embodiment). In FIG. 4, communication is performed from the communication terminal 100-i to the communication server apparatus 200, but the reverse (communication from the communication server apparatus 200 to the communication terminal 100-i) may be performed.

Step ST13:
In step ST12, once the data communication between the communication terminal 100-i and the communication server device 200 is completed, the communication server device 200 starts the timer 201 and causes the time to be counted.
Step ST14:
In the communication terminal 100-i, a text editor is activated, a key input, or a predetermined event occurs as described in the first embodiment. Since the text editor activation, key input, or predetermined event is the same as that described in the first embodiment, the description thereof is omitted.

Step ST15:
When the text editor is activated, a key is input, or a predetermined event occurs in step ST14, the control unit 7 of the communication terminal 100-i causes the communication unit 2 to transmit predetermined data (pseudo data). The pseudo data may be any data such as dummy data with no contents and empty data that are set to the communication server device 200 as the transmission destination. Information indicating what type of data is being created may be included in the pseudo data, but the characters input in the text editor, the unattached data in the data folder being referred to, and being captured by the camera 8 Since it is not preferable in use that data that does not indicate the user's intention to transmit, such as an image of the above, it is preferable that information regarding the contents of the data being created is not included in the pseudo data.
Step ST16:
The communication server device 200 resets the timer 201 on condition that the pseudo data is received from the communication terminal 100-i in step ST15.

Step ST17:
When the pseudo data described in step ST16 is not received for a predetermined time after the timer 201 is started in step ST13 or the timer 201 is reset in step ST16, that is, the count of the timer 201 exceeds a predetermined time In this case, the process proceeds to step ST18. Needless to say, illustration is omitted for the case where new transmission / reception of data occurs, but in this case, it goes without saying that the process returns to step ST11.
Step ST18:
In step ST17, when the count of the timer 201 reaches a predetermined time, the communication server device 200 performs group communication of the communication terminal 100-i and another communication terminal 100 (which has performed group communication with the communication terminal 100-i). All are ended, and the group communication processing of the communication server apparatus 200 itself is also ended. Note that the group communication is specifically performed when a group communication start request from the communication terminal 100-i is received and one management area (site) is set for the group communication. The location address of this site is indicated in the parameter included in the group communication start notification sent to all members when the group communication is started, and the group communication is started by the group that has accessed (participated) the site. This site manages data such as a group member management table, a speech reservation table, a transmission / reception data management area, and a group communication control work area. That is, the end of group communication in step ST18 is the release of a site for this group communication, and an end notification may be transmitted to each member.

  As described above, in the second embodiment of the communication system 1000 according to the present invention, after the communication between the communication terminal 100-i and the communication server device 200 is completed, the communication terminal 100-i does not exceed a predetermined time. When the predetermined event does not occur and the pseudo data is transmitted from the communication terminal 100-i to the communication server apparatus, the communication server apparatus 200 resets the timer 201 to cause the communication terminal 100-i and the other communication terminal 100 to be reset. Since the group communication process of the communication server apparatus 200 is continued, the situation where the communication server apparatus 200 ends the group communication despite the occurrence of a predetermined event for the user to transmit as group communication. Can be avoided.

The present invention is not limited to the embodiment described above.
That is, the present invention can be applied even if various changes, combinations, sub-combinations, and substitutions are made with respect to the components of the above-described embodiment within the technical scope of the present invention or an equivalent scope thereof.

  In the present invention, for simplification of description, the example is divided into the first embodiment and the second embodiment, but both operations may be performed simultaneously. That is, even when both the communication terminal side and the communication server device side have timers, the present invention can be implemented without any problem if both timers can be reset when a predetermined event occurs. it can.

  In the above-described embodiment, an example in which the present invention is applied to group communication by PoC has been described. However, the present invention is not limited to this, and other various group communication that performs one-to-many data communication is also described. Applicable.

  The processing of the control unit 7 of the communication terminal 100-i of the above-described embodiment may be executed entirely by a computer based on a program, or at least a part thereof may be executed by hardware.
