For example, as shown in FIG. 3, the display unit 14 displays a number (index) corresponding to the numeric keypad, the name of each person of the communication partner group member, and group member information related to the state of the communication partner.

  FIG. 2 is a functional block diagram of the communication terminal device 10 of FIG. The communication terminal device 10 includes a transmission unit 21, a reception unit 22, a display unit 14, an input unit 23, a control unit 24, first and second communication session holding units 25 and 26, and a group member acquisition unit 27. These are constructed by a program given to the CPU. The transmission unit 21 performs data transmission from the communication terminal device to the base station. The receiving unit 22 receives data from the base station to the communication terminal device. In PoC, packet data communication is particularly suitable for data transmission / reception. The control unit 24 controls a call by the transmission unit 21 and the reception unit 22, and controls input on the input unit 23 and display on the display unit 14. The display unit 14 displays information instructed from the control unit 24. The input unit 23 receives operation inputs from the numeric keypad 16 and the Talk button 17.

  The communication session information holding units 25 and 26 hold PoC communication session information. For example, the first communication session holding unit 25 holds session information related to communication with a group, and the second communication session holding unit 26 holds session information related to communication with a specific member in the group. The group member acquisition unit 27 acquires and stores information on each member of the communication destination group. The information on the communication destination group is displayed on the display unit as illustrated in FIG.

  FIG. 4 shows a state during a group call performed using the communication terminal device 10 (10A, 10B, 10C). When the owner of the communication terminal device 10A holds a conference as an organizer, the organizer designates a group stored in the group member acquisition unit 27 by, for example, pressing the Talk button 17, and notifies the PoC server 30 of it. To do. The PoC server 30 establishes a session with the organizer and establishes a session with each of the terminal devices 10B and 10C that are group members. These pieces of session information are stored in the first communication session holding unit 25 of the communication terminal devices 10A, 10B, and 10C owned by each member including the organizer in the PoC server 30.

  At this point, there is no difference in the status of the conference between the organizer and each participant, after which only the difference between the sender and receiver of the call, that is, the difference between the speaker and the other members. become. Speaking within the group is performed by subsequently pressing the Talk button 17 constituting the first speaking right acquisition button. The call while the Talk button 17 is being pressed is transmitted to other constituent members. The display unit 14 displays the member information as shown in FIG. The first floor is given to the participant who first pressed the Talk button 17 in the group after the session is established, and is maintained by the participant by holding it down.

  When a conference participant wants to individually communicate with the terminal device 10B of the specific member “B” in the group using his / her terminal device 10A, refer to the display on the display unit 14, The numeric keypad “2” for designating the terminal device 10B of the specific member “B” is pressed. When the numeric keypad “2” is pressed, the control unit 24 refers to the information of the group member acquisition unit 27, designates the member “B”, and transmits an individual communication request to the PoC server 30. The PoC server 30 sends an individual communication request to the terminal device 10B of the member “B”, and when the session is established, the terminal device 10B of the member “B” and the terminal device of the participant who transmitted the individual communication request. Send to 10A.

  The participant who transmitted the member “B” and the individual communication request stores the session information in the second communication session holding unit 26 of the communication terminal device. That is, in this embodiment, each numeric keypad functions as a session establishment request button for the corresponding participant. At this time, for inter-group communication, a communication session for a specific member is established in a state where the communication session is maintained without being disconnected. This individual session information is held in the second communication session holding unit 26.

  Since the member who has established the session individually stores both the session information of the group and the individual session information after that, by pressing the Talk button or the corresponding numeric keypad, both the already established sessions are displayed. You can make calls. That is, in this example, the speaker can operate the first speaking right acquisition button to speak to the group after finishing the communication with the specific member “B”. Since the session for group communication is held in the first communication session holding unit 25 and the session is maintained as it is, a message to the group is simply made by pressing the Talk button 17. At this time, the communication with the specific member “B” is finished, but the information held in the second communication session holding unit 26 is held for a certain period of time. If communication with another specific member, for example, individual communication with member “E” is required, the key 5 is pressed in the same manner.

  FIG. 5 is a flowchart showing the processing of the control unit 24 of the terminal device 10A owned by the conference organizer. When the processing starts and the Talk button 17 is pressed (step S1), the control unit 24 refers to the group member acquisition unit 27 and transmits a group communication session establishment request (step S2). In response to this, the PoC server 30 establishes a session with a member of the corresponding group. When the session is established, the fact is transmitted to the terminal device 10A, so the control unit 24 stores the established session information in the first communication session holding unit 25 (step S3).

  Next, when the Talk button 17 is pressed (step S4), the control unit 24 transmits a request for acquisition of the right to speak to the PoC server 30 (step S5). The PoC server 30 confirms that there is no other speaker, and transmits a statement of approval to acquire the right to speak to the terminal device 10A. If the organizer wishes to perform individual communication during the meeting, the partner of the individual communication is designated and the numeric keypad is pressed (step S6). The control unit 24 identifies the pressed numeric keypad, refers to the group member acquisition unit 27, and transmits an individual communication session request designating the other party to the PoC server 30 (step S7). The PoC server 30 confirms that the other party has not acquired the right to speak, establishes a session, and transmits a message to that effect to the terminal device 10A.

  The control unit 24 stores the session information in the second communication session holding unit 26 (step S8). When the session is established, the fact is displayed on the display unit 14. Next, on the assumption that a certain time has not passed (step S9), when the same keypad pressed first is pressed on the terminal device 10A (step S10), the control unit 24 holds the second communication session. Referring to unit 26, a request for speaking right specifying the individual communication partner is transmitted (step S11). When the individual communication ends, the second session remains established, and the process shifts to a group communication session. The second communication session holding unit 26 stores a predetermined number of times after the ten key is not pressed even after a certain time has elapsed after the individual communication session is established (step S10), and after the shift to the group communication, If the individual communication is not resumed again after a lapse of time (step S6), the information is discarded (step S12).

  In the above-described embodiment, an example has been described in which a numeric keypad corresponding to a specific member is pressed to make a call to the specific member. In the following embodiment, an example has a mode in which a numeric keypad corresponding to a specific member is pressed to make a call to the specific member, and a mode in which a numeric keypad corresponding to the specific member is pressed to make a call with a member other than the specific member Will be explained.

  When performing PoC communication between groups, you may want to speak to other members in the group except for specific members. In the present embodiment, in the inter-group communication, the right to speak for inter-group communication is acquired by pressing the Talk button (first speaking right acquisition button) as in the previous embodiment. Here, when the numeric key (second speaking right acquisition button) is pressed while the Talk button is being pressed, the right to speak for individual members in the group other than the individual member “other” assigned to the numeric key is acquired. The right to speak may be acquired after establishing a communication session for each individual member, or after a group other than the selected specific member is generated and the communication session for that group is established. It may be a thing.

  When the numeric keypad is pressed, switching between the first mode for acquiring the right to speak for a specific member and the second mode for acquiring the right to speak for a specific member “other” is performed by simultaneously pressing the Talk button. . For example, when only the numeric key is pressed without pressing the Talk button, the first mode is operated, and when the numeric key is pressed simultaneously with the pressing of the Talk button, the second mode is operated. When only the Talk button is pressed, normal inter-group communication is performed. In the present embodiment example, utterances to other group members excluding a specific member can be performed by simultaneously pressing a Talk button for speaking to the entire group and a “tenkey” for speaking to a specific member. It is possible to intuitively understand the remarks to the “excluding specific person” and realize a simple operation.

  In the said embodiment, when performing communication with respect to a group, it is possible to simply communicate with a specific person belonging to the group, and smoother communication can be achieved.

  In each of the above embodiments, the communication terminal apparatus capable of PoC communication has two types of speaking right acquisition buttons. The first speaking right acquisition button is a button for acquiring a right to speak for group communication. The second speaking right acquisition button is a speaking right acquisition button for communication with respect to a specific member belonging to a group performing group communication. The operator operates the first speaking right acquisition button to perform group communication. Here, when it becomes necessary to temporarily communicate with a specific member in the group, the operator operates the second speaking right acquisition button. Thereafter, if the operator needs to speak again to the entire group, the first speaking right acquisition button is pressed. As described above, individual communication for specific members in the group can be easily performed.

  Instead of the member display shown in FIG. 3, an icon display in accordance with the numeric keypad arrangement may be used as shown in FIG. Moreover, in the said embodiment, although it was set as the specific member which belongs to a group and a group, each group or specific member which belongs to a several group group and a group group may be sufficient. In addition, it is possible to switch between two or more specific persons by using three or more communication session holding units.

  Although the present invention has been described based on the preferred embodiment, the communication terminal device of the present invention is not limited to the configuration of the above embodiment, and various modifications and changes can be made from the configuration of the above embodiment. Those subjected to are also included in the scope of the present invention.
