さがあった。A specific example of such a service is a facsimile box service, which is a post office box-like service in facsimile communication. In this service, when a subscriber with a facsimile receiving terminal instructs the storage device to start a facsimile box, all messages received during that time (hereinafter referred to as correspondence) are stored in the facsimile box for up to two hours after that. Ru. The subscriber can read out the messages in the facsimile box at any time, but if the number of messages in the facsimile box is 20.
If there are as many as ~30 pages, while the message is being received, all incoming telephone calls to the subscriber will be turned away because they are in communication (Pino). Therefore, in such a case, there is an inconvenience in that even if the user wants to make an emergency call to the subscriber, he or she cannot do so.
本発明は上記欠点をなくすため、蓄積呼は必ずしも緊急

が可能となる。First, FIG. 3 will be explained. 4 is a terminating subscriber, 5 is a subscriber exchange, 6 is a transit exchange, 7 is a storage device, and 8 is a subscriber exchange. While the storage device 7 is transmitting image information prx '1 to the facsimile terminal of the subscriber 4, the subscriber exchange 8
When the local exchange 5 receives an immediate call termination request to the subscriber 4 from The exchange 8 then returns a message such as "Please wait for a while" to the caller. The subscriber exchange 5 further transmits an interruption request (1) signal for disconnecting the stored call to the trunk exchange 6 over the common line, and the exchange 6 further sends an interruption request (2) signal to the storage device 7 over the common line. Send by. The storage device 7 starts monitoring the end of one page transmission, sends a response (1) signal back to the exchange 6, and further sends a response (2) signal back to the exchange 5.
The exchange 5 waits until the subscriber line of the subscriber 4 becomes hook-on. When the storage device 7 finishes transmitting one page of image information PIX 'i, it sends a page end signal EOM to the destination terminal via the communication line, and if the destination terminal has received the page normally, it sends a page reception confirmation signal MCF. It is returned to the storage device 7. The storage device 7 interrupts the transmission of the subsequent page even if there is a subsequent page, and sends a disconnection request signal DCN to the destination terminal via the communication line to disconnect the communication path between the storage device 7 and the subscriber 4. . When the destination terminal receives the DCN, it ends the reception operation and puts the subscriber line into 7 quotas/state. When the local exchange 5 detects the hook-on state, it sends a disconnection request signal requesting the intermediate exchange 6 to disconnect the line between the storage device 7 and the local exchange 5 that was being used for the subscriber 4. LCN 1
The exchange 6 then disconnects the line and notifies the storage device 7 of the disconnection request signal LCN2. Note that the LCA 1 and LCA2 signals are returned as acknowledgment responses to the LCN 1 and LCN 20 signals, respectively. When the subscriber exchange 5 receives the LCA 1 signal,
In order to connect a waiting immediate call to the subscriber 4, a ringing tone RGT'i is sent to the subscriber 4, and when the subscriber hooks off with the telephone, a connection completion signal is sent back to the originating local exchange 8. After this, an immediate call to the subscriber 4 can be made.

。During this time, the main memo IJ5e of the subscriber exchange 5 stores the status of the subscriber line 4c indicating that it is communicating by a stored call and is receiving a message. When subscriber 9 sends a message requesting immediate call connection to subscriber 4 via telephone 9&, central control unit 8b sends an immediate call termination request signal to terminating subscriber 4 via common line device 8di. When the central control unit 5b receives the signal via the common line device 5di, it checks the status of the subscriber line 4c in the main memory 5C and determines whether communication is in progress using a stored call. Dekatsu knows that a message is being received. Therefore, a standby signal is sent back to the originating exchange Ifa8 via the common line device 5d, and
Similarly, the central control unit 6b transmits an interruption request (1) signal to the trunk exchange 6 via the common line device 5d (i7). When the central control unit 6b receives the interruption request signal, it further sends an interruption request to the common line device 6d'j (via the storage device 7). (2) Send a signal. Main control unit 7
When b receives the interruption request (2) signal, the transmission control unit 7a
to suspend sending messages to subscriber 4,
When the transmission control unit 7a receives the MCF signal for the page being transmitted, it transmits the DCN signal to the subscriber 4 via the communication line, and cancels the message transmission process regardless of whether there is a subsequent page. When the facsimile terminal 4b receives the F'1DCN signal, it stops receiving operation and turns on the subscriber line 4c. state. When the central control unit 5b detects the on-hook state (indicating that the subscriber line 4c is not in use) of the subscriber line 4c via the exchange unit 5al, it immediately rewrites the status display of the subscriber line 4c in the main memory to indicate that a call is being received, and then switches the subscriber line 4c to the relay exchange. 6, transmits the LCN 1 signal via the common device 5d (-1 central control unit 6bij applies, C
Upon receiving the N1 signal, the storage device 7 and the subscriber exchange 5

方法である。In the following explanation, the predetermined trigger for interrupting message transmission from the storage device is the time when one page transmission is completed, but it may also be in the middle of one page, or when the reverse K1 page is interrupted. If the page is in the middle of transmission and there is a large amount of remaining information on the page and the user can wait several minutes until the page conversion is completed, there is a method of not allowing interruptions. In other words,
This method does not apply the present invention if it is determined that the immediate call originator will be kept waiting for more than enough time until a predetermined opportunity.
