DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A telephone conference system and a telephone communication method according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a block configuration of a telephone system of a telephone conference according to an embodiment of the present invention. In FIG.
In a telephone device 1 of a telephone conference, an external / extension telephone 10, an external / extension telephone 11, and an extension telephone 12 are connected to a conference trunk 20 which is a line connection means for a conference, and any telephones 10 to 12 participate in a telephone conference. can do. FIG. 2 is a block diagram of the communication device 1 shown in FIG.
2 withdraws from the conference call and a new outside line / extension telephone 13
Is a diagram showing a case where the extension telephone 12
FIG. 4 is a diagram for explaining a case where the outside line / extension telephone 13 takes a turn and participates in a telephone conference.

In these figures, the automatic exchange 1 includes:
The central processing unit 2 is connected by a communication line. The communication line is an ISDN line, a telephone line, or the like. The central processing unit 2 is provided with a judging unit 15 for judging whether or not it is the dial information in the telephone conference by referring to the special number storage memory 30 as a search means. In this determination unit 15, the dial information in the telephone conference is read from the special number storage memory 30. When the determination unit 30 determines that the read dial information is in a state in which a dial call can be made, the external / extension telephone 13 that newly participates in the telephone conference is replaced with the conference trunk 20 in place of the extension telephone 12 that drops out. The external telephone / extension telephone 10 and the external / extension telephone 11, which are telephones participating in other telephone conferences, are connected by a conference trunk 20.

In FIG. 1 and FIG. 2, the maintenance terminal device 3 inputs a transfer special number to the communication device 1 in a conference state. From the maintenance terminal device 3 to the special number storage memory 3
When the special number information to be input to 0 is in a conference state, when the judgment unit 15 judges that the special number information is a transfer special number,
It can be set to a state where dial reception is possible. Note that the numeral receiving device 40 is a device for receiving numeral information.

Next, the operation of the telephone system for a telephone conference according to the embodiment of the present invention will be described with reference to FIGS. FIGS. 3 to 5 are flowcharts for explaining the operation of the telephone system of the telephone conference according to the embodiment of the present invention. In the description of these flowcharts, FIGS.
Shall be referred to.

FIG. 3 is a flowchart showing a process when the extension telephone 12 shown in FIGS. 1 and 2 receives a hooking operation signal. When the extension telephone 12 receives the hooking operation signal, first, the communication path between the extension telephone 12 and the conference trunk 20 is disconnected by the line disconnecting means (step 300, hereinafter referred to as S300). Next, S3
Proceeding to 10, the extension telephone 12 and the numeral receiving device 40 are connected, and a dial receiving state is set (S310). Thus, the above processing ends.

Is searched (S400). At this time, when it is determined that the special number read from the special number storage memory 30 is other than the transfer special number from the conference call state (YE in S410).
At step S), the process proceeds to step S430 to perform processing for another special number. When it is determined that the special number is not a special number other than the transfer special number from the conference call state (NO in S410), the connection between the extension telephone 12 and the numeral receiving device 40 is maintained, and the state in which dial reception is possible is maintained (S420). )do it,
The above processing ends.

FIG. 5 is a flowchart showing a process when the extension telephone 12 recovers from a call between the extension telephone 12 and the extension / external telephone 13. When the extension telephone 12 is restored from the call between the extension telephone 12 and the extension / external telephone 13, the communication path between the extension telephone 12 and the numeral receiving device 40 is disconnected (S500). Next, the process proceeds to S500, and the extension telephone 12 is restored. Next, the process further proceeds to S520,
The extension / external telephone 13 is connected to the external / extension telephone 10, the external /
The telephone is connected to the conference trunk 20 to which the extension telephone 11 is connected, and a conference call is established (S520). From the above,
The processing up to this point is terminated.

Next, the operation of the telephone system for a telephone conference according to the embodiment of the present invention will be specifically described with reference to FIGS. The transfer special number from the three-party conference state
The maintenance terminal 3 registers the information in a memory area in the special number storage memory 30. Next, when the extension telephone is in a three-party conference connected to the extension / external telephone 10 and the extension / external telephone 11 by the care trunk 20, the extension telephone 12 needs to be replaced with another extension / external telephone 13. Occurs, the extension telephone 12 hooks.

At this time, the central processing unit 2 disconnects the extension telephone 12 from the three-party conference trunk 20 while keeping the telephone conversation state between the extension / external telephone 10 and the extension / external telephone 11, thereby enabling dial reception.

Thereafter, when the extension telephone 12 dials the transfer special number, the central processing unit 2 searches the special number storage memory 30 and determines that it is a transfer special number from the three-party conference state. State.
The extension telephone 12 dials the number of the extension / external telephone 13 and, when the extension telephone 12 is restored after the extension / external telephone 13 responds, the central processing unit 2 replaces the extension telephone 12 with the extension / external telephone 10. , 11 can be connected to the conference trunk 20 to enter a three-party conference state.

According to the embodiment of the present invention described above,
The conference participants can be easily changed, and even if the conference participants are changed, it is possible to participate in the telephone conference. Further, according to the present embodiment, it is possible to easily replace a new participant in a conference call with either an analog or digital telephone.
