For this reason, the group communication is started in a state where the communication terminal A has not transmitted the request for participation in the group communication to the communication terminal F.
- the user of the communication terminal F since the request for participation in the group communication has not been transmitted to the communication terminal F, the user of the communication terminal F does not know that the group communication is being performed. In some cases, a call is requested (step ST107). In addition, there is a case where the user of the communication terminal F does not know that the group communication is in progress and desires the user of the communication terminal A to participate in the group communication. Since communication terminal A is notified of an incoming call from the communication network even during group communication, it will leave the group communication. Since the group communication itself is maintained by the communication between the server and each communication terminal, the communication terminal A is maintained even if it temporarily leaves. Then, the communication terminal A disconnects the incoming call from the communication terminal F without making a call.
- the communication terminal A transmits to the communication terminal F that the group communication has already been performed (step ST108), and notifies that the group communication is being performed.
- the group communication terminal is still participating in the maximum number of people. It is preferable that the content confirms whether or not he / she wishes to participate in the Drupo Communication.
- step ST108 The user of the communication terminal F who has already received the notification that the group communication is being performed in step ST108 rarely participates in the group communication as a response to the notification. If desired, the communication terminal F transmits a request for participation to the communication terminal A. In this example, communication terminal F transmits a participation request SMS to communication terminal A (step ST1 09).
- the processing in step ST109 may be configured as follows. That is, when receiving a notification confirming whether or not communication terminal F wishes to participate in group communication in step ST108, the control unit of communication terminal F displays this confirmation content. Then, the user of the communication terminal F selects Z not desired.
- the control unit of the communication terminal F transmits a participation request SMS to the communication terminal A, and when “desired” is selected, communication is performed. If terminal A does not wish to participate in group communication! If communication terminal A does not need to perform any further processing, participation by communication terminal E changes. If you don't do it, you will be able to participate.
- the communication terminal A Since the communication terminal A, which is the organizer communication terminal, receives the request for participation from the communication terminal F and receives V, the communication terminal A desires that the communication terminal F participate in the group communication. Can be recognized. However, in communication terminal A, it is assumed that communication terminal E is in a standby state, and the user of communication terminal E wants to participate in group communication on the way. Despite communication terminal F requesting to participate, communication terminal A continues to treat communication terminal E as a standby state. Then, if communication terminal E is subsequently allowed to participate in group communication, the maximum number of communication terminals that can simultaneously perform group communication will be five, so communication terminal F cannot participate in group communication.
- communication terminal A re-checks whether or not communication terminal E power, which is handled as waiting, wishes to participate again (performs communication response determination), and determines that there was no communication terminal E power participation desire.
- the communication terminal E is treated as not participating in group communication, and the communication terminal A transmits an SMS indicating that it cannot participate in group communication to the communication terminal E (ST111).
- SMS SMS indicating that it cannot participate in group communication
- communication terminal A will not retransmit the request for participation in group communication to communication terminal E so that communication terminal E will not want to participate.
- the communication terminal A is prevented from resending the participation request SMS to the communication terminal E (step ST 112).
- the control unit of communication terminal E receives the notification that group communication cannot be participated in step ST111, it matches the previously received group communication start notification (specifically, the group communication specified in each notification). ID, sender, server address, and other parameters), and even if a user requests access to the group communication server based on a previously received start request for matching group communication, it is regulated not to connect.
- step ST112 Since communication terminal A does not retransmit SMS to communication terminal E in step ST112, communication terminal E will no longer participate in group communication. Therefore, delete the registration of communication terminal E that is not participating in group communication from the member list of communication terminal A. Then, since communication terminal F wants to participate in group communication, communication terminal F is added to the member list of communication terminal A and it is treated as waiting (step ST113). That is, as shown in FIG. 4C, in the member list of communication terminal A, communication terminal E is deleted and communication terminal F is registered as waiting.
- Communication terminal A which has been treated as waiting for communication terminal F, transmits a request to participate in group communication to communication terminal F.
- communication terminal A transmits an SMS to communication terminal F (step ST114).
- This SMS includes data of the group communication management site information (network address, oral login ID, etc.) necessary for communication terminal F to participate in group communication.
- Communication terminal F which has received a transmission to participate in group communication from communication terminal A, has already transmitted a request for participation to communication terminal A in step ST109. Therefore, if communication terminal F receives an SMS from communication terminal A in step ST114, communication terminal F participates in group communication (step ST115).
- communication terminal F participates in group communication, information on the group communication management site necessary for participating in the loop communication sent from communication terminal A to communication terminal F in step ST111 (network Participate based on data such as address and login ID.
- step ST117 group communication is performed with communication terminal A, communication terminal B, communication terminal C, and communication terminal F (step ST117).
- communication terminal A updates the registration state of the member list (step ST116). That is, as shown in FIG.
- the communication terminal B, the communication terminal C, the communication terminal D, and the communication terminal F are registered in the list.
- Step ST 118 Note that communication terminal E will no longer participate in group communication in the future, and only communication terminal A and communication terminal F, which are the parties' terminals, recognize that communication terminal F has participated in group communication. ing. For this reason, after the update of the member list registration state is completed in step ST116, it is necessary for terminals B, C, and D other than communication terminal A and communication terminal F to recognize that fact. Therefore, communication terminal A notifies communication terminal B, communication terminal C, and communication terminal D that communication terminal E withdraws future group communication participation and that communication terminal F has newly joined group communication (update notification). (Step ST 118).
- the member list is recorded and held in the communication terminal A that is the organizer, and recorded and held in the server device of the group communication. It may be updated as follows.
- the control unit of the communication terminal A can be realized by transmitting a notification requesting the update separately to the server device at each step in which the member list should be updated and notifying the update contents. .
- each communication terminal has been mainly described as an embodiment of the present invention in that each control unit receives and transmits a notification in each step.
- the control unit displays a display screen in order to notify the display unit of each communication terminal that the notification has been received or the member has been changed. Prefer to generate and display.
- the embodiment of the present invention has been described by taking a mobile phone as an example.
- the present invention is not limited to this. If the mobile phone has a group communication function, a PHS (Personal Handy phone System), personal Needless to say, it can be applied to computers, PDAs, portable game machines, car navigation systems, etc.!
