Description

  The present invention relates to a communication terminal apparatus capable of performing group communication such as PTT (push to talk).

  In recent years, communication modes of communication terminal devices typified by mobile phones have diversified, and communication terminals capable of performing packet communication using an IP (internet protocol) network in addition to conventional voice calls by circuit switching The device is widely used.

  As one of such diversified communication modes, there is a so-called “group communication” capable of exchanging data such as characters in a group in real time. One of the group communications that has recently attracted attention is a technology called PTT (push to talk over cellular) or PoC (push to talk over cellular). In PoC, a plurality of communication terminal devices forming a group can perform a real-time voice call by VoIP (voice over internet protocol) (Patent Document 1). In addition, voice data can be communicated simultaneously with image data composed of character data and digital information.

  When starting this group communication, the host terminal device which becomes the host of the group communication among the plurality of communication terminal devices first performs the process of starting the group communication. Then, the organizer terminal device generates and transmits a group communication invitation notice to other communication terminal devices (participant terminal devices) registered in the organizer communication terminal device. The group communication invitation notification is a notification inquiring that the organizer terminal device participates in group communication with other communication terminal devices.

  The owner of the participant terminal device that has received the group communication invitation notification can tell the organizer terminal device whether to participate in the group communication and decide to participate in the group communication. Once PTT group communication is started, the owner of the communication terminal device who wishes to speak depresses a predetermined button (PTT button) provided on the communication terminal device, so that the owner's speech request is transmitted to the communication server. Sent to. The communication server receives a speech request from each communication terminal device and gives a speech right to one communication terminal device. The communication terminal device given the right to speak transmits the owner's voice data to the communication server, and the communication server transmits the voice data to other communication terminal devices all at once. Thereby, a real-time voice call is performed by a plurality of communication terminals forming group communication.

  Further, as described above, the group communication technique can perform communication using not only voice but also character data and image data. FIG. 10 shows a state of the display unit of the communication terminal apparatus when character data and image data are transmitted / received by group communication. Hereinafter, the state of the screen shown in FIG. 10 is referred to as “main screen state”. As can be seen from FIG. 10, when character data and image data are transmitted / received in group communication, bidirectional communication is performed between the organizer terminal and the participant terminal in a system equivalent to chat.

Further, when the “character input” soft key displayed at the bottom of FIG. 10 is selected and determined, the screen state shown in FIG. 11 is entered. The state of this screen is hereinafter referred to as “character input screen state”. In this character input screen state, the communication terminal apparatus accepts an input of a comment displayed in the “main screen state” from the user.
JP2007-116735

  If character data is transmitted / received between two communication terminal devices using the group communication described above, the following problems may occur. Hereinafter, this problem will be described with reference to FIG.

  FIG. 12 shows a sequence diagram of communication terminal device A (user name: Yamagata) and communication terminal device B (user name: forest) performing communication between the two parties, and communication terminal device A at that time. It is the figure which showed the screen state of the communication terminal device.

  During group communication, from the state in which the main screens 1001 and 2001 are displayed on both the communication terminal device A and the communication terminal device B (step S1001, step S2001), the user of the communication terminal device A (“Yamagata”) The screen of the communication terminal device A is switched to the state of the character input screen 1002 (step S1002a). Then, in a state where this character input screen 1002 is displayed, the user of communication terminal apparatus A performs character input. However, as shown in the screen 2002 shown in FIG. 12, while the user of the communication terminal device A is inputting characters, the user of the communication terminal device B (“Mori”) performs the group communication end process. When the communication is performed in the device B (step S2002), the communication terminal device A receives a notification of the end of the group communication (step S1002b), displays an end screen 2003, and ends the group communication of the communication terminal device B. Even in the communication terminal apparatus A that is inputting, the end screen 1003 is displayed and the group communication ends (steps S1003 and S2003).

  Therefore, the text created by the user of the communication terminal apparatus A in a state where the character input screen 1002 is displayed is not transmitted to the communication terminal apparatus B. Furthermore, in a state where the group communication has ended, the text that was being created during the group communication is deleted from the storage unit of the communication terminal device A. Therefore, there is a possibility that the group communication may end without transmitting the text created by the user of the communication terminal apparatus A to the user of the communication terminal apparatus B.

  Hereinafter, the communication terminal apparatus according to the present invention will be described based on an optimum embodiment.

  FIG. 1 is a block diagram illustrating a configuration example of a communication system in which a communication terminal device according to the present invention is used. As shown in FIG. 1, the communication system is configured by connecting a communication terminal device 100-i (i is a positive integer) and a PTT server 200 (communication server in claims) via a network 300. The network 300 is a data communication network including a base station provided by a telecommunications carrier and other facilities necessary for data communication, and may be a network that performs wireless communication, or may be a wired network. A combination of wireless communication and wired communication may be used.

  The communication terminal device 100-i is a wireless communication terminal such as a mobile phone, and is connected to the PTT server 200 via the network 300 and performs group communication by PTT (Push To Talk) according to the control of the PTT server 200. . The group communication is data communication with another communication terminal device 100-j (j is a positive integer other than i), and data transmitted by this data communication includes, for example, voice data of a call, image data, For example, character data.

  In the communication system in which the communication terminal apparatus according to the present embodiment is used, one communication terminal apparatus that is permitted to transmit by the PTT server 200 among a plurality of communication terminal apparatuses 100-i transmits data to other communication terminal apparatuses. Send. A communication terminal device that desires data transmission transmits a communication permission request to the PTT server 200.

  The PTT server 200 is a server device that manages group communication between the communication terminal devices 100-i.

  When receiving a group communication start notification from one communication terminal device, the PTT server 200 calls the communication terminal of the other party in response to the request and establishes a communication session using SIP (Session Initiation Protocol) or the like. After establishing a communication session, the PTT server 200 relays data transmitted from one communication terminal device to a plurality of communication terminal devices. That is, the PTT server 200 once receives data transmitted from the communication terminal device on the transmission side to the communication terminal device on the reception side, and transfers it to the communication terminal device on the reception side. Note that the PTT server 200 may communicate with the communication terminal device by communication using a communication protocol other than SIP.

  FIG. 2 is a block diagram showing main components of the communication terminal device 100-i.

  The antenna 101 performs voice communication, for example, under the control of the control unit 110. In addition, when performing two-way communication with the communication server 200, data is transmitted / received via the network 300.

  The communication unit 102 converts the data transmitted from the control unit 110 into a wireless communication format. Conversely, data in a wireless communication format received by the antenna 101 is decoded and transmitted to the control unit 110. In the claims, the described communication unit may be one in which the antenna 101 and the communication unit 102 are regarded as one.

  The operation unit 103 is composed of a number of keys that generate a signal mainly when pressed and transmit the signal to the control unit 110. There are several types of keys, for example, a numeric keypad on which one-digit numbers from 0 to 9 are written in order to input a telephone number. The numeric keypad is also used when inputting characters. A selection key for selecting a display item displayed on the display unit 107 is also provided. The selection key is composed of four keys indicating the directions of up, down, left, and right. Further, a determination key for generating an instruction signal for causing the control unit 110 to execute content corresponding to the item selected by the selection key is also provided. In addition, a soft key that can be input in accordance with the display content displayed at the bottom of the display unit 107 is also provided. In this case, the soft key is arranged at a location adjacent to the lowermost stage of the display unit 107. In addition, when the communication terminal device 100-i is in a half-fold type, a side key is provided so that it can be operated from the outside even in a closed state (a state in which the mobile phone is completely folded). There may be.

  The audio processing unit 104 has a function of converting the signal transmitted from the control unit 110 into an audio signal for the speaker 105. In addition, the voice signal input from the microphone 106 is also converted so that the control unit 110 can understand it.

  The speaker 105 is provided on the outer surface of the communication terminal device 100-i. The voice signal transmitted from the voice processing unit 104 is converted into sound.

  The microphone 106 has a function opposite to that of the speaker 105. As a first step, a sound generated outside the communication terminal device 100-i is acquired and converted into an audio signal. As the next stage, the converted audio signal is transmitted to the audio processing unit 104.

  The display unit 107 is an information providing unit that provides information that can be visually recognized by a user using the communication terminal device 100-i. For example, the display unit 107 is made of an LED (light emitting diode) display. Moreover, it may be produced by organic EL (electro-luminescence). In addition, an image display device using liquid crystal may be used.

The storage unit 108 stores various data used for processing in the control unit 110. For example, a computer program provided in the control unit 110, an address book for managing personal information such as a telephone number or an email address of a communication partner, an audio file for playing a ring tone or an alarm sound, various setting data, a program Holds temporary data used in the process.
The storage unit 108 is configured by, for example, a non-volatile storage device (non-volatile semiconductor memory, hard disk device, optical disk device, etc.), a randomly accessible storage device (eg, SRAM, DRAM), or the like.

  The communication terminal device 100-i also has a camera module (not shown). With the camera module, the user of the communication terminal device 100-i can take an image outside the communication terminal device 100-i as image data of digital information. This digital information is stored as image data in the storage unit 108 by the control unit 110. Alternatively, it can be transmitted to the communication unit 102 by the control unit 110 and transmitted to the PTT server 200 via the network 300.

  The control unit 110 comprehensively controls the overall operation of the communication terminal device 100-i. That is, various processes of the communication terminal device 100-i (voice communication performed via the circuit switching network, PTT group communication, creation and transmission / reception of e-mail, browsing of Internet websites, etc.) The operation of each unit described above (transmission / reception of signals in the communication unit 102, input / output of audio in the audio processing unit 104, display of images on the display unit 107, etc.) is controlled so as to be executed in an appropriate procedure according to .

  For example, the control unit 110 includes a computer that executes processing based on a program (operating system, application, etc.) stored in the storage unit 108, and executes the above-described processing according to a procedure instructed in this program.

  The control unit 110 also has a function of changing the data size of image data captured by the camera module and image data transmitted from another communication terminal device 100-i. For example, image data with QVGA resolution (320 × 240 pixels) can be changed to image data with QQVGA resolution (160 × 120 pixels).

  FIG. 3 shows a communication terminal apparatus 100-1 (corresponding to the communication terminal apparatus A in the conventional example described in FIG. 12) and a communication terminal apparatus 100-2 (described in FIG. 12) using the communication system shown in FIG. It is a sequence diagram when group communication is performed between two parties (corresponding to communication terminal apparatus B in the conventional example). Hereinafter, according to the time series shown in the sequence diagram of FIG. 3, an embodiment of the present invention will be described using the communication terminal apparatus 100-1 and the communication terminal apparatus 100-2. As in the description of the conventional example, the user name of the communication terminal apparatus 100-1 is “Yamagata” and the user name of the communication terminal apparatus 100-2 is “Mori”.

  First, group communication is started and performed between the communication terminal device 100-1 and the communication terminal device 100-2 by the procedure as described above (step S301). Immediately after the start, the display units 107 of both the communication terminal device 100-1 and the communication terminal device 100-2 are in the main screen state. The main screen state at this time is a state in which only two names of “Yamagata” which is the user name of the communication terminal apparatus 100-1 and “Mori” which is the user name of the communication terminal apparatus 100-2 are displayed. It is.

  Hereinafter, the movement of the communication terminal device 100-1 (user name: Yamagata) will be mainly described.

<< About movement of communication terminal apparatus 100-1 >>
During group communication (step S301), the control unit 110-1 of the communication terminal device 100-1 notifies the presence of the communication terminal device 100-1 to “online” to the PTT server 200 (step S302). Presence means that the participation status of the communication terminal device 100 in the group communication is displayed on the display unit 107 of the communication terminal device 100 of the communication partner. The above-described presence of “online” indicates a situation in which it is possible to connect to the PTT server 200 to participate in group communication and perform group communication with other communication terminal devices 100. There are other types of presence, such as “Away” indicating that the user temporarily leaves the group communication, or “Not participating” in the group communication since the start of the group communication. In addition, during group communication, there is a presence called “during editing” indicating that character input for group communication is being performed in the communication terminal device 100.

  Communication terminal apparatus 100-1 transmits presence “online” to PTT server 200. Next, the PTT server 200 transmits the state of “online” of the communication terminal apparatus 100-1 to the communication terminal apparatus 100-2.

  As the next stage, it is assumed that the screen of the display unit 107-1 of the communication terminal device 100-1 is changed to the character input screen state by the input from the operation unit 103-1 of the communication terminal device 100-1 (step S303). At this time, the portion operated on the operation unit 103-1 is a soft key corresponding to “character input” displayed at the center of the lowermost part of the display unit 107-1 (see FIG. 10). When the soft key is pressed, the control unit 110-1 of the communication terminal device 100-1 changes the screen of the display unit 107-1 from the main screen state to the character input screen state.

  At this time, the control unit 110-1 changes the presence of the communication terminal device 100-1 to “editing” (step S304). In step S304, information indicating that the presence has been updated (first information in the claims) is notified to the communication terminal device 100-2 via the PTT server 200 (step S305).

  FIG. 4 schematically shows how the first information is transmitted to the communication terminal device 100-2 in step S305. The control unit 110-1 shifts the display of the display unit 107-1 from the state of the main screen to the character input screen state by receiving a press of a soft key corresponding to the display at the center of the lowermost stage of the display unit 107-1. And change. When changing the screen state, the control unit 110 transmits the first information to the communication terminal device 100-2 (the partner communication terminal device in the claims) via the PTT server 200.

  As the next step, the control unit 110-1 that has changed the screen state of the display unit 107-1 to the character input screen state waits for a character input to be performed in the operation unit 103-1 (step S306).

  As the next step, the control unit 110-1 detects whether or not the screen state of the display unit 107-1 has been changed from the character input screen state to the main screen state by an input from the operation unit 103-1. S307). The input from the operation unit 103-1 is performed by pressing a soft key corresponding to the display displayed at the bottom of the display unit 107-1 (see FIG. 11).

  Next, the control unit 110-1 checks whether or not a character input has been performed in step S306 (step S308). If the character input is performed in the state of step S306, the control unit 110-1 transmits the message input in step S306 to the PTT server 200 (step S308 / Y, step S309). At the same time, the control unit 110-1 updates the presence of the communication terminal device 100-1 to “online” (step S310), and transmits the updated presence “online” to the PTT server 200 (step S311). The presence of “online” transmitted at this time is the second information in the claims. When the control unit 110-1 detects that no character input has been performed in the state of step S306 in the step S308 (step S308 / N), the control unit 110-1 performs the step of step S309. The process proceeds to step S310 without going through.

  Hereinafter, the content described above will be described in detail with reference to FIG.

  FIG. 5 schematically shows how information is transmitted from the communication terminal device 100-1 to the communication terminal device 100-2 via the PTT server 200 from step S306 to step S311. In step S306, the control unit 110-1 accepts the character input “Today is hot” from the operation unit 103-1. When the soft key corresponding to the [OK] display displayed at the bottom center of the display unit 107-1 is pressed, the control unit 110-1 inputs the screen state of the display unit 107-1 as characters. Change from the screen state to the main screen state. At the same time, the control unit 110-1 transmits the message “Today is hot” and the second information to notify that the presence has been updated from “editing” to “online” via the PTT server 200. Send to 100-2. At this time, the display section 107-2 of the communication terminal apparatus 100-2 displays the transmission message “Today is hot” transmitted from the communication terminal apparatus 100-1.

  Next, the movement of the communication terminal device 100-2 (user name: forest) will be mainly described.

<< About movement of communication terminal apparatus 100-2 >>
As described with reference to FIG. 3, the communication terminal apparatus 100-2 recognizes that the presence of the communication terminal apparatus 100-1 is “online” at the stage of step S301 (step S312). Next, as described above, the first information is received from the communication terminal apparatus 100-1 via the PTT server 200 (step S313).

  FIG. 6 is a diagram illustrating in detail the display unit 107-2 of the communication terminal device 100-2 when the process proceeds from step S312 to step S313. FIG. 6A shows the state of the display unit 107-2 in step S312. At this time, the displayed screen is a main screen display state in which the character data and / or image data exchanged in step S301 is shown. Next, when the first information is received from the communication terminal device 100-1, as shown in FIG. 6B, the control unit 110-2 of the communication terminal device 100-2 communicates with the display unit 107-2. The presence “editing” received as the first information is displayed in the vicinity of “Yamagata” which is the user name of the terminal device 100-1.

  In this way, the presence of the communication partner is updated and displayed on the display unit 107-2, so that “forest”, the user of the communication terminal device 100-2, can communicate with the communication terminal device 100- It becomes possible to know that “Yamagata”, which is one user, is in the middle of inputting characters. In this way, the present invention reminds “Forest” of “Yamagata” to “Forest” and causes the occurrence of acts that waste “Yamagata” character input such as “Forest” leaves group communication. Can be reduced.

  As described above, when the display unit 107-2 of the communication terminal apparatus 100-2 is in the main screen state, the control unit 110-2 receives the first information and displays the presence “editing” on the display unit 107-2. indicate. However, even in the state where this display is being performed, there is a possibility that the communication terminal device 100-2 may perform an operation of leaving the group communication by an input from the operation unit 103-2 due to an operation mistake of “Forest” or the like ( Step S315).

  In response to such a problem, the control unit 110-2 performs a pop-up display or the like on the display unit 107-2 when the operation unit 103-2 inputs group communication disconnection, and groups the “forest”. A means for inquiring whether or not to really leave the communication;

  FIG. 7 describes the means for solving the control unit 110-2 described in the previous paragraph in more detail. FIG. 7A shows the state of the display unit 107-2 at the stage of step S314. In this screen state, when the control unit 110-2 receives an input for leaving the group communication from the operation unit 103-2 (pressing the soft key corresponding to the display on the lower right side of the display unit 107-2), FIG. As shown in b), a pop-up display as shown in FIG. 7B is performed on the display unit 107-2 based on the first information (step S316). At this time, the control unit 110-2 asks the question “Yamagata” is currently being entered in the pop-up display. Do you really want to leave the group communication? ”And“ Yes ”and“ Yes ”to answer the question. “No” is displayed.

  At this time, if the input of “Yes” is received from the operation unit 103-2, the control unit 110-2 desires that “Forest” ignores the character input of “Yamagata” and leaves group communication. Interpret and leave group communication. However, if “NO” input is accepted from the operation unit 103-2 at this time, the control unit 110-2 interprets that the group communication disconnection has been selected due to an input error due to “MORI”, and pops up. The display is turned off and the display of the display unit 107-2 is returned to the screen display shown in FIG.

  By adopting the configuration as described above, it is possible to recognize that “Yamagata” is being input from a pop-up display as well as the presence “editing” display for “Forest”. Therefore, it is possible to further reduce the occurrence of an act of wasting the character input of “Yamagata” compared to the case where only the presence “editing” display is performed by the control unit 110-2.

  As described above, the communication terminal apparatus 100-2 displays the presence “editing” of the communication terminal apparatus 100-1, and further described above when receiving the group communication disconnection input from the operation unit 103-2. A pop-up display notifies the user (“Mori”) that the user (“Yamagata”) of the communication partner is inputting characters.

<< Presence and pop-up settings >>
However, for the user of the communication terminal apparatus 100-2, there may be a case where the presence “editing” display shown in FIG.

  In addition, when the user of the communication terminal device 100-2 (“Mori”) is a user who is familiar with group communication, the user of the communication terminal device 100-1 (“Yamagata”) performs group communication with an incorrect operation while inputting characters. The possibility of leaving is low. Therefore, when “Forest” is a user who is well-versed in group communication and the control unit 110-2 receives an input for leaving the group communication in the operation unit 103-2, the following cases can be considered. That is, the input is a case where “Forest” knew that “Yamagata” was being input, and wanted to leave the group communication. In such a case, the pop-up display becomes a factor that hinders rapid group communication disconnection, and is not convenient for the user “forest”.

  In response to the above-described problem, the communication terminal device 100-2 can set whether to display presence / pop-up display during group communication.

  FIG. 8 shows the display contents that the control unit 110-2 displays on the display unit 107-2. The control unit 110-2 receives an input from the operation unit 103-2 when group communication is not performed (for example, when an environment setting screen of an application that performs group communication is displayed on the display unit 107-2). As a result, the screen display shown in FIGS. 8A and 8B is performed.

  FIG. 8A shows a case where the control unit 110-2 inquires of the user whether to display the presence of the communication partner ("Yamagata" in this embodiment) on the display unit 107-2 during the group communication. This is the state of the display unit 107-2. At this time, the control unit 110-2 waits for an input in which “Yes” or “No” is selected from the cross key and the determination key provided in the operation unit 103-2. If “Yes” is selected, the control unit 110-2 displays “editing” in the vicinity of the user name of the communication partner as shown in FIG. When “No” is selected, the display unit 107-2 does not display “Editing” in the next group communication.

  FIG. 8B shows the pop-up display shown in FIG. 6B on the display unit 107-2 when the control unit 110-2 receives an input for leaving the group communication from the operation unit 103-2 during the group communication. This is the state of the display unit 107-2 when inquiring to the user whether or not to display. At this time, the control unit 110-2 waits for an input in which “Yes” or “No” is selected from the cross key and the determination key provided in the operation unit 103-2. If an input of “Yes” is received, the control unit 110-2 displays a pop-up when receiving an input for leaving the group communication, as shown in FIG. 7B. When the input of “NO” is received, the control unit 110-2 can leave the group communication as it is without performing a pop-up display at the next and subsequent group communication leaving. Therefore, it is possible to leave the group communication smoothly.

  The communication terminal apparatus 100-2 further includes such means, thereby solving the above-described problem.

  Whether or not the communication terminal apparatus 100-1 on the user “Yamagata” side also notifies the communication terminal apparatus 100-2 of a presence display as if “mori” can be set in the communication terminal apparatus 100-2. Can be set. The movement of the communication terminal device 100-1 at this time will be described with reference to FIG.

  FIG. 9 is a diagram illustrating a state of the display unit 107-1 when the group communication is not performed in the communication terminal device 100-1. This screen display is a screen state that the control unit 110-1 displays on the display unit 107-1 when the environment setting of the application that performs group communication is performed. At this time, after the screen is displayed on the display unit 107-1, the control unit 110-1 selects and determines the “Yes” or “No” option from the cross key and the determination key of the operation unit 103-1. I will wait for you. When “Yes” is selected, the control unit 110-1 operates according to the embodiment as described above when the group communication is next activated. When “NO” is selected, the control unit 110-1 does not transmit the first information to the communication terminal device 100-2 when the group communication is started next. Therefore, even if the presence or pop-up display is set on the communication terminal device 100-2 side, the presence of the “editing” presence or group is displayed on the display unit 107-2 of the communication terminal device 100-2. The pop-up display that is displayed when the communication is disconnected is not performed.

  Since the communication terminal device 100-1 has such a means, the user (“Yamagata”) of the communication terminal device 100-1 himself / herself (Yamagata) is transferred to the user (“Mori”) of the communication terminal device 100-2. It is possible not to indicate that input is in progress. This setting is provided in the communication terminal apparatus 100-1 assuming the case described below. In other words, when the control unit 110-1 accepts in the operation unit 103-1 the content that the “Yamagata” should be notified to the “forest”, the “Yamagata” is being edited on the display unit 107-2. Then it would be inconvenient if it was known to the “forest”. This means is provided in the communication terminal apparatus 100-1 assuming such a case. Note that this means may be usable (setting changeable) when group communication is being performed.

As described above, according to the present invention, it is possible to provide a communication terminal device that reduces the possibility that input content to be transmitted from one communication terminal device to the other communication terminal device cannot be transmitted in group communication. In the present embodiment, an example in which the state during character input by the operation unit 103-1 is notified to the communication terminal device 100-2 is shown, but the input performed by the input of the operation unit 103-1 is character. Not limited to input. For example, even when the image data stored in the storage unit 108-1 of the communication terminal device 100-1 is prepared to be transmitted in group communication by “Yamagata”, the control unit 110-1 does not input characters. You may perform the operation | movement similar to time.

  The display on the display unit 107-2 that the presence “editing” described in FIG. 6B disappears from the display unit 107-2 when the “second information” is received in step S318 in FIG. You may do it.

  The present invention has been described by taking a cellular phone as an example. However, in addition to mobile phones, electronic devices such as PHS (Personal Handyphone System), PDA (Personal Digital Assistants), and other electronic devices capable of bidirectional communication with other terminals using the Internet, such as personal computers, The present invention is applicable.
