Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone group call method and a group call system that enable a caller to simultaneously talk with a plurality of desired call recipients.

[0002]

2. Description of the Related Art In principle, existing various telephone systems such as a fixed telephone, a PHS, and a mobile telephone realize a one-to-one two-way call between a sender and a receiver. For this reason, the individual telephone devices, the exchanges, the relays, and the communication lines that connect these components that constitute these various telephone systems are configured to realize a two-way call.

This telephone system for two-way communication is important for eliminating the intervention of a third party in the communication between individuals and maintaining the "secret of communication" which is the basic right of the people. Therefore, it was a premise of the basic technical structure of the telephone system.

However, there are quite a few cases where it is desired to simultaneously make a call (hereinafter referred to as a "group call") in a group of three or more people based on the will of the telephone user. In particular,
In the younger generation who have a high ownership rate of PHS and mobile phones, for example, when three or more people meet at a meeting place or time, conventionally, each member has to make multiple calls individually. However, if such a group call is possible, it will be easy to make one call. Therefore, there have been many requests for group calls in the past.

However, in the existing telephone system,
As mentioned above, because it is built based on the two-way calling system, if it is possible to make such a group call, a significant technical change and update of the exchanges and repeaters that make up the telephone system will be performed. It requires a huge capital investment.

[0006] In the existing telephone system, there is a telephone conference system in order to realize a simultaneous call for three or more people similar to a group call.

[0007] In this telephone conference system, in order to make simultaneous calls for three or more people, the conference call organizer previously discusses with the conference call participants the date and time of the conference and the participants Notify the date and time of the conference call and the telephone number you have decided.

At the time of the conference call, each participant calls the same telephone number for the notified conference call and connects to the exchange for the conference call system.
When all the participants' phones are connected, a telephone conference can be held.

[0009]

However, the multiple call system using such a conference call system has various problems as described below. (1) It is necessary to determine the date and time of holding the conference call in advance. (2) The conference call organizer needs to inform the participants of the start time of the conference call in advance. (3) Each participant of the conference call needs to connect to the line by calling the same telephone number for simultaneous conversation at a predetermined date and time.

As described above, it is very troublesome to inform the participants of the time of the conference call and the telephone number for the conference each time the conference is held.

Further, the participants in the conference call may target participants in a wide range of areas registered for the purpose of conversation rather than in the same company.

The present invention utilizes the technical configuration of the telephone conference system in the existing telephone system as described above, and allows the caller to make a call at any time without making the callee notice the group call in advance. The present invention provides a telephone call method and a telephone call system capable of making a group call with any other party.

In that case, the telephone number of the call center displayed in the incoming call history displayed on the mobile phone 7D is called. The participant 7D inputs his own telephone number according to the voice guide from the simultaneous line connection device 1. The simultaneous line connection device 1 searches for the simultaneous conversation group to which the participant 7D should enter, and if the simultaneous conversation is continuing, the simultaneous line connection device 1 connects to the group call to enable the simultaneous conversation. When the simultaneous conversation has already ended, the simultaneous line connecting device 1 sends the end guidance to the effect that the group call has ended to the mobile phone 7 of the participant 7D.

The group call fee is charged on a pay-as-you-go basis for everyone who speaks from the call center 3. However, in the present embodiment, the caller is set to bear the call charge for all the persons who have spoken.

Further, in the present invention, the group call center telephone number (03-XXXX-YYYY) is set in advance.
Can be registered in his / her mobile phone 7 for a group call. In addition, if the telephone number is designated by TO, Cc, and Bcc, it is possible to know which type the group call was made to. In the phonebook memory of the mobile phone 7, register "You are making a group call" as the group call phone number and name. Registration is TO: 03-XXXX-YYYY, Cc: 03-X
XXX-AAAAA, Bcc: 03-XXXX-BBBB
And When a group call is received, the screen of the mobile phone 7 displays "03-XXXX-YYYY" for you when it is TO. Similarly, in the case of Cc, "You have a group call with Cc." 03-XXXX-AAA
A is displayed. Similarly, in the case of Bcc, "You have a group call on Bcc." 03-X
XXX-BBBB is displayed on the display screen. From this display, the conditions for participating in the simultaneous conversation can be known and the necessity of participating in the simultaneous conversation can be immediately understood.

Further, by setting up the call center 3 for each large corporation and setting a dedicated telephone number, the reliability and security of the call center 3 can be enhanced.

Here, the operation of the group call will be described. FIG. 9 shows a flowchart for explaining the flow of the group call operation.

The caller of the group call logs in to the telephone directory database site on the Internet and calls his telephone directory database 2. For example, htt
p: // www. anycall. net / asp? To log in (S1). At this time, the sender ID and the URL are verified (S2). When the login is authenticated, the registered group is displayed (S3). A group to be called this time is selected from the groups registered in the telephone directory database 2 (S4). The telephone number of the telephone directory database 2 registered in the selected group is read out and displayed on the screen of the own mobile telephone 7 (S5).

From the list of telephone numbers displayed on the screen, check boxes (TO, Cc, Bcc) of the participation conditions of the participants who participate in the current group call are checked to determine the participants (S6). When the check is completed, the caller gives a call instruction (S7). Upon receiving the instruction, the simultaneous line connection device 1 makes a simultaneous call to the participants including the caller (S8). Call center 3 calls all participants including myself. The number of calls can be decided by default. For example, call 10 times.

The person who answers the phone can simultaneously talk with all the other participants (S9, S10). If the caller does not answer the phone for some reason, a voice guidance to the effect that the group call has not been established due to the caller's convenience is sent to the participant answering the phone, and the process ends (S12).

As described above, in the group call system of the present invention, the caller manages the telephone directory database 2 and makes a call, but other called group call participants answer the call and join the group call. All you have to do is do nothing else. Furthermore, the telephone directory database 22 allows thousands of participants to register for a group call.

The group call method and the group call system of the present invention select a plurality of telephone numbers registered in the telephone directory D / B2, make a call (call) to the selected telephone numbers at the same time, and sequentially receive the received number.
