0075[0050] The information about the above address book and group is memorized by storage part 108 as personal information. When control part 110 changes the memory content and data structure as a personal-information-management department, it is To manage about this personal information. To. [ in / sure enough / for a function / storage part 108 ]

0076[0051] In this way, when control part 110 makes a selection decision of the member who performs group communication, it is control part 1. 10 registers the member into member list 109 of storage parts 108. When a sponsor communication terminal tries to perform group communication, the start demand of group communication is made to the method (communication terminal) of the partner registered into this member list 109.

0077[0052] transmitting the purport of a start demand to communications server device 200 from communications department 102, and accepting this start demand, when control part 110 makes the start demand of group communication -- communications server device 200 , -- the data of To be sent information is received in communications department 102. The information for starting and group communication is included in the data of this information, for example, it is an object for group communication management. A network address, its ID for login, etc. of a site are contained. Control part 110 is a connoisseur. The data of these pieces of information acquired from Trust server apparatus 200 is used, and it is group communication Starting passage. Generate Knowledge and shave the data of this information from communications department 102 to the member of group communication. It transmits to Re.

0078[0053] When the response of the purport that it participates in group communication from a member to a group communication demand is replied and this is received in communications department 102, control part 110 is a data transceiver place of PTT. Reason (group communication) is started. Power sent to all other parties by whom the start demand of group communication was registered into member list 109 The partners' all the members are 3 to group communication. which replies the response of a purport which carries out Addition and which divides and comes out, [0054] When the speaking key of key input section 103 is pressed, control part 110 communicates from communications department 102. An utterance demand is transmitted to server apparatus 200. Communications server to this utterance demand If the notice of the permission from device 200 is received in communications department 102, Control part 110 is my. Strange [ in voice processing part 104 / to voice data ] in the audio signal inputted from Kurohon 106 Conversion is carried out and it transmits to communications server device 200 from communications department 102. on which a speaking key is pushed, and a case change Voice De from the communication terminal under and utterance Receive(ed) - Tha into an audio signal in voice processing part 104 in communications department 102, and are Output about a sound from speaker 105. To. Besides the data of a telephone call sound, it is transmission and reception of various kinds of data of image data, musical piece data, etc. It carries out similarly.

0079[0055] In this way, as group communication is performed, it is member list 1 of sponsor communication terminals. The communication terminal power which is not registered into 09 and has not participated in the group communication concerned may also newly have a request of intervention to group communication. In such a case, group communication The request of 3 mosquito A from a communication terminal which has not carried out 3 mosquito A is a connoisseur about communications department 102 of a sponsor communication terminal. Processing of reception is performed by Do control part 110.

0080[0056] When processing of reception is performed by control part 110 about the purport of the request of 3 mosquito A, The start demand of Darube communication deletes a line trap Strong partner for the response of the purport that it participates in group communication among the other parties registered into member list 109 from registration of member list 109.

0081[0057] Instead, register into member list 109 the partner of a communication terminal who showed the purport of the request of 3 mosquito A as a partner who performs group communication in a present progressive. Since group communication is what is performed with the partner registered into member list 109 of sponsor communication terminals, Partner mosquito of a communication terminal in which the purport of the request of 3 mosquito A was shown By being registered with Hotel list 109, it is the communication terminal. It can be made to participate in the group communication in a present progressive now.

0082[0058] (Two) control parts 110 perform the following processings, when performing group communication as a participant communication terminal.

0083[0059] in which communications department 102 of a participant communication terminal receives the transmitted notice of a group communication start (3 Callot request) first according to control of control part 110 from communications department 102 of a sponsor communication terminal. And when it is expected that the owner of a participant communication terminal participates in group communication The owner performs predetermined operation about key input section 103 of a participant communication terminal. When predetermined operation is performed about power part 103 much more, control part 110 is a sponsor communication terminal. It transmits receiving and participating in group communication through communications department 102.

0084[0060] Group communication is started as (1) explained by carrying out like this. The user of a predetermined communication terminal is a sponsor communication end as a partner of the group communication which a sponsor communication terminal performs. It may not register with the member list of last. The user of a communication terminal is sponsor communication. When not registering with the member list of terminals, the communication terminal is a sponsor communication terminal. Power The notice of a group communication start is not received. Therefore, the communication terminal is GRU. It is a sponsor communication terminal about the purport that it participates in group communication to the notice which shows holding of A communication. It becomes impossible to participate in the group communication concerned by transmitting.

0085[0061] however -- registering with the member list of sponsor communication terminals, even if it is such a case -- V -- the communication terminal of and a user can transmit carrying out participating hope to Darube communication to a sponsor communication terminal as a participant communication terminal.

0086[0062] That is, a sponsor communication terminal is registered into member list 109 in the partner of a communication terminal who transmitted that as (1) explained by receiving carrying out participating hope to a user's communication terminal power group communication which is not registered into a member list. And the communication A terminal can be made to participate in the group communication in a present progressive now.

0087[0063] next, the flow for enforcing the group correspondence procedure which consists of a communication terminal which has the composition mentioned above -- a figure -- explain with reference to the flow chart shown in 3. sponsor communication terminal the figure showing the registration situation of member list 109 -- while referring to 4, it explains.

0088[0064] a figure -- in the example shown in 3, communication terminal A is a sponsor communication terminal. communication terminal B, communication terminal C, communication terminal D, communication terminal E, and communication terminal F should turn into a participant communication terminal, or should participate in A [ Dull - ] communication -- it becomes and a communication terminal. for example, in this example, group communication comes out simultaneously The number of the maximums of the number of the communication terminals to cut is five.

0089[0065] The user of a sponsor communication terminal and becoming communication terminal A first makes decisions that group communication is performed with the user of communication terminal B, communication terminal C, communication terminal D, and communication terminal E. And the thing for which the user of communication terminal A operates the key input section of communication terminal A, Communication terminal B by which the control part of communication terminal A is managed by the storage part, communication terminal C, communication terminal D, communication The information of the user of communication terminal B, communication terminal C, communication terminal D, and communication terminal E is read among the information of the user of terminal E and communication terminal F.

0090[0066] At this time, it is To in order that the user of communication terminal B, communication terminal C, communication terminal D, and communication terminal E may perform group communication on the member list of storage parts of communication terminal A with the user of communication terminal A. It is registered as Who. In this way, a member list is created (step ST101). Figure As shown in 4A, in the created member list, they are communication terminal B, communication terminal C, and a communication end. The user of communication terminal E is registered an end D.

0091[0067] It is A to communication terminal B, communication terminal C, communication terminal D, and communication terminal E of the partner as whom communication terminal A should perform group communication after a member list is created in step ST101. The request of the purport that it participates in loop communication is transmitted. It is Sending by SMS about the purport of a request that communication terminal A participates in this example to communication terminal B, communication terminal C, communication terminal D, and communication terminal E. Trust is carried out (step ST102). Site for group communication management required for this SMS in order that communication terminal B, communication terminal C, communication terminal D, and communication terminal E may participate in group communication The data of information, including a network address, ID for login, etc., is contained.

0092[0068] U of communication terminal B among the users of communication terminal B, communication terminal C, communication terminal D, and communication terminal E who received the request of the purport that it participates in group communication, in this example, communication terminal C, and communication terminal D 1 THE assumes that a decision which participates in group communication was made. And communication terminal B, communication It is to group communication to the request of the purport that terminal C and communication terminal D participate in group communication. If it participates, it will answer to communication terminal A (step ST103).

0093[0069] Communication terminal A has transmitted SMS in step ST102 to communication terminal B, communication terminal C, communication terminal D, and communication terminal E. However, it actually participates in group communication. Since those of Oh is communication terminal B, communication terminal C, and communication terminal D, a response makes the registration state of a member list communication terminal A update (step ST104). Figure Like and by which communication terminal B, communication terminal C, and communication terminal D are registered into the member list of communication terminals A which were shown in 4B. Communication terminal E which did not answer treats as under standby.

0094[0070] After making the registration state of a member list update by step ST104, terminal A makes terminal B, terminal C, terminal D, and group communication start (step ST105).

0095[0071] Communication terminal E has not answered that and To participate in group communication in response to the request of the purport that it participates in group communication. That is, communication terminal A is 3 in step ST102. Although the communication terminals which transmitted Request are communication terminal B, communication terminal C, communication terminal D, and communication terminal E, Communication terminal E which is a partner of one of those communication terminals is in the state "with nonparticipation" to group communication. However, in communication terminal A, it is communication terminal E. It is treated that it is a waiting state, it is that of To go, and the user of communication terminal E is to group communication by the middle. He can wish to participate. Then, communication terminal A is A to communication terminal E. The purport of the request of intervention is broadcast again to loop communication. In this example, communication terminal A broadcasts SMS again to communication terminal E (step ST106).

0096[0072] Furthermore, the user of communication terminal A has made decisions that he will make it the user of communication terminal B, communication terminal C, communication terminal D, and communication terminal E at the beginning as a partner who performs group communication. the -- a sake -- communication terminal F -- receiving -- the purport of the request of intervention to the group communication from communication terminal A is transmission are in the state which was not carried out and group communication is started -- and To.

0097[0073] however, since the purport of the request of 3 mosquito A was not transmitted to group communication at communication terminal F, the user of communication terminal F also has [ that it is / group / under communication, and ] Unknown and a thing which it comes out and requires a telephone call from communication terminal A (step ST107). what the user of communication terminal F is group communicating -- Unknown and purport that come out and it carries out participating hope to the group communication concerned It is, also when you wish to the user of communication terminal A. Communication terminal A is group Through. Since the notice of a mail arrival call is made from a communications network even if it is among Trust, it is - And group Through. It secedes from Trust. the group communication itself is connection by communication with a server and each communication terminal -- maintenance -- For a Being done reason, communication terminal A is maintained even if it breaks away temporarily. And communication terminal A is cut, without talking over the telephone to and the arrival from communication terminal F. Here, it once answers. Guidance of the purport that Call is not made may be sent out and power may also be cut. And communication end At last, group communication is already performed, and A transmits Purport to communication terminal F (step S T108), and reports group communicating. It transmits in step ST108. As the notice of the purport that it is group communicating to communication terminal F carried out, group communication terminal [ ] -- the maximum number still participates [ ] -- , case Well , and The are contents which check whether it is Impartiality which wishes the intervention in A [ Dull - ] communication to communication terminal F -- good Up .

0098[0074] It is a communication terminal about the information of the purport that it is already group communicating in step ST108. The users of communication terminal F which alpha mosquito also received are rare in intervention to the group communication concerned as an answer to information. When carrying out Desire, it transmits carrying out participating hope from communication terminal F to communication terminal A. Book In an example, communication terminal F transmits SMS wishing participating to communication terminal A (Step ST1 09). As processing in step ST109, it may constitute as follows. that is, does he wish 3 mosquito A to group communication to communication terminal F in step ST108? the case where the notice of the contents which checks whether it is no is received -- the control part of communication terminal F -- inside of this check he displays Capacity and the user of communication terminal F wishs -- it Z carries out and makes Absent choose Here, when "Wish" is chosen, the control part of communication terminal F transmits participating hope SM S to communication terminal A, It is [ as opposed to / when "wish " is chosen / communication terminal A ] group communication. Wish to participate! If a purport is connected, communication terminal A will be a line trap about subsequent processings. Complete sake, It is made to participate when the mind of the user of communication terminal E stops changing and participating. To also comes made.

0099[0075] Communication terminal A which is a sponsor communication terminal receives carrying out participating hope from communication terminal F, and it is that of VTo go, and communication terminal A expects that communication terminal F participates in group communication, and can recognize and To. However, it is Treated that communication terminal E is a waiting state in communication terminal A. The user of Re and communication terminal E is Idea about wishing to participate in group communication on the way. It is carrying out constant. communication-terminal A Although communication terminal F has advanced participating hope, smell. Treating The and communication terminal E is continued with a waiting state. And it is group communication about communication terminal E after that. If it is made to participate, it will become five sets of the maximum of the number of the communication terminals which can perform group communication simultaneously. It becomes impossible for communication terminal F to participate in group communication.

0100[0076] Communication terminal A checks again the existence of participating hope of the communication terminal E power currently treated under standby there (a response judging is carried out during communication), judging that there was no communication terminal E power participating hope communication terminal E treats a It was case (step ST110) as not participating in group communication -- connoisseur intervention of Communication terminal A be possible to group communication to communication terminal E -- it is transmission about SMS of purport It carries out (ST111). By doing so, an opening is securable for the maximum participating frame of group communication. It can accumulate and, also in power, communication terminal F can participate now in group communication on the way. Communication terminal A is communication terminal E power. It is a pair to communication terminal E so that the purport that participating hope is carried out may not come from now on. It carries out and makes it not broadcast the purport of the request of intervention again to group communication. this example -- communication end A should broadcast SMS of a participating request again to communication terminal E at last -- -- it is made like (Step ST 112). The control part of communication terminal E cannot be participated [ of the group communication in step ST111 ]. If a notice is received, Consistency with the notice of a start of the group communication received before is aimed at (ID and the sender of group communication who are specified by each notice in concrete ). server address etc. -- it is based on comparison of a parameter, and the start demand received in the past [ of group communication in agreement ] Even if the access demand to a group communications server is made by the user, it does not connect. It regulates to obtain.

0101[0077] Communication terminal A does not broadcast SMS again to communication terminal E by step ST112, and participating of communication terminal E in group communication from now on is lost by that of Noodle. Then, communication end It is Deleting about registration of communication terminal E which does not participate in group communication from the member list of A at last. Removal is carried out. And since he wishes for communication terminal F to participate in group communication, he is a connoisseur. In the member list of Communication terminal A, while adding communication terminal F, it treats as under standby (step ST113). namely, a figure -- it is shown in 4C -- as -- the member list of communication terminals A -- It is, communication terminal E is deleted and communication terminal F is registered as under standby.

0102[0078] Communication terminal A which treated communication terminal F as under standby transmits the request of the purport that it participates in group communication to communication terminal F. In this example, communication terminal A transmits S MS to communication terminal F (step ST114). In this SMS, communication terminal F is 3 to group communication. The data of the information on the site for group communication management required in order to carry out Addition, including a network address, ID for mouth Gui A, etc., is contained.

0103[0079] Communication terminal F which received transmission of the purport that it participates in group communication from communication terminal A has already transmitted carrying out participating hope to communication terminal A in step ST109. others Because -- communication terminal F participates in group communication the case where SMS is received from communication terminal A in step ST114 (step ST115). Communication terminal F is To join to group communication. In the To case It participates based on the data of the information on the site for group communication management required in order to participate in A [ Dull - sent from communication terminal A to communication terminal F in step ST111 ] communication, including a net Worker dress, ID for login, etc.

0104[0080] And group communication is performed by communication terminal A, communication terminal B, communication terminal C, and communication terminal F (step ST117). Communication terminal A makes the registration state of a member list update at this time (step ST116). namely, a figure -- it was shown in 4D -- as -- Member of communication terminal A Communication terminal B, communication terminal C, communication terminal D, and communication terminal F are made to register into a strike.

0105[0081] In addition, participating of communication terminal E in group communication from now on was lost, and communication terminal A which is a terminal of the party concerned, and communication terminal F recognize the purport that communication terminal F participated in group communication. Therefore, in step ST116, it is a letter of registration of a member list. After renewal of voice is completed, terminals B, terminals C, and terminals D other than communication terminal A and communication terminal F need to enable it to recognize that. Then, communication terminals A are communication terminal B and communication. Communication terminal E reports that withdrawal and communication terminal F newly participated future group communication intervention in group communication to terminal C and communication terminal D (Step ST 118). (renewal notice)

0106[0082] Communication end which is a sponsor about a member list according to explanation of the present invention as explained above Record and maintenance of are done within A at last, and they are and Power. It may update so that record and maintenance of may be done with the server apparatus of group communication. In this case, the control part of communication terminal A is while transmitting separately the notice which requests updating to a server apparatus in each step which should update a member list. As those contents of updating are notified, If realization can be carried out.

0107[0083] Each communication terminal is although One and The were mainly shown in the point that each control part performs receiving and transmission of a notice at each step, as an example of the present invention, By not coming out this much, the control part of each communication terminal notifies a user of reception of a notice, a participating member's change, etc. to the indicator which each communication terminal has, whenever it receives a notice or a member list is updated. It is good Up to generate and display a display screen, in order to carry out.

0108[0084] If it is what has a group communication function which drops off in what is limited to this although the cellular phone was explained to the example about the embodiment of the present invention above, PHS (Personal Ha ndy phone System), a personal computer, PDA and a handheld game machine, car navigation Also until it says that Well , such as a Geijon system, and The can also be applied /!
