Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-call service using a one-touch dial in a telephone terminal. By incorporating an IC memory and a CPU in a telephone terminal, various telephone services have come to be provided to subscribers. Multi-functionalization of services is progressing, such as recording services such as answering machines and message phones, and calling services using speed dials and one-touch dials.

The one-touch dial system is a system in which a single or a plurality of destination numbers registered in advance are sequentially transmitted by a one-touch key operation. For a small number of destinations, they are registered in a built-in memory of a telephone terminal. By calling the one-touch dial key of the subscriber, it is possible to make a call to the other party who is sequentially registered. In the case of a large number of destinations, such as market research and opinion polls, the destination number can be extracted from the memory and automatically sent by registering it in the memory of the private branch exchange, etc. by the operator. it can.

[0003]

However, in the conventional one-touch dial method, although it is possible to register a plurality of destinations in the one-touch dialing, when the other party is absent or busy, the line is disconnected and the call is reissued. Had to do. Also,
In some cases, when busy, there is a waiting service etc., but with this method you can not call while waiting
In addition, I sometimes forgot that I was waiting, so I could not respond immediately.

[0004]

The present invention is a service for solving these dissatisfactions. When the other party is absent or busy, calls are made in the order registered in the one-touch dial, and the The purpose is to allow the caller and the other party to check the status of the mailbox when the multiple names are all absent and the message is recorded in the mailbox of the exchange.

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, 1 is a calling side terminal, 2 is a calling side exchange, 3 is a switching network, 4 is a called side exchange, 5 is a called side terminal, and 6 is a called side mailbox. One-touch dialing on the calling terminal 1 allows multiple destination telephone numbers, T
Mailbox IDs corresponding to _EL 1, T _EL 2, T _EL 3, ..., T _EL M, and the destination number T _EL 1 registered at the beginning are registered in advance.

Further, a mailbox having a destination number T _EL 1 is set in the called-side mailbox 6 of the called-side exchange 4. With this configuration, it is possible to inform the other party of the call without using the recalling and waiting functions even if all the other parties registered in the one-touch dial are busy. Becomes

[0007]

The process flow chart of the present invention is shown in FIG. In the figure, (1) The calling party presses the one-touch dial of the calling side terminal 1. (2) Call the first registered destination number T _EL 1. (3) Check whether the other party's number T _EL 1 is busy. (4) If not busy, check whether it is ringing. (5) If it is not ringing, connect to the other party. Make a call. (6) If ringing, wait for connection until the other party answers. (7) If the destination number T _EL 1 is busy in (3) above, the destination number T _EL 2 registered next is called. (8) It is checked whether the destination number T _EL 2 is busy. (9) If it is not busy, the same process flow as in the above (4) to (6) is performed. (10) In (8), if the destination number T _EL 2 is busy, the destination telephone numbers registered next are sequentially called, and (11) the destination number registered at the end. Call _TEL M. (12) It is checked whether the destination number _TEL M is busy. (13) If it is not busy, the same processing flow as the above (4) to (6) is performed. (14) In (12) above, if the destination number T _EL M is busy, the next registered T _EL 1 mailbox is called. (15) If you connect to the T _EL 1 mailbox, (16) Register the message to be sent to T _EL 1. (17) When the message registration is completed, the line is disconnected by on-hook.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a connection sequence diagram of the present invention is shown in FIGS. Description will be made with reference to the principle configuration diagram of FIG. FIG. 3 shows a sequence diagram until the mailbox number is taken out, and FIG. 4 shows a sequence diagram of recording in the mailbox and reproducing from the mailbox. The figure shows the states at the calling side terminal, the calling side exchange, the called side exchange and the called side terminal.

When the calling side terminal goes off-hook, the calling side exchange is activated to send a dial tone to the calling side terminal.
Check the dial tone at the calling terminal and use one-touch dial 1
push. Removed subscriber number of T _EL 1 which is registered in the calling terminal, and automatically sends a dial signal T _EL 1.

A calling signal is sent to the calling exchange to secure a loop for the called exchange, but the called terminal T _EL
Since 1 is busy, the called side terminal T _EL 1 and the called side exchange are in a connected state. Therefore, a busy tone is sent from the called exchange to the calling exchange, a busy tone is output to the calling terminal, and the calling terminal detects the busy tone.

When the calling exchange detects a busy tone, it retrieves the next registered subscriber number of T _EL 2 and T _EL 1
The same operation as the processing for is performed, and if busy, the subscriber number registered next is taken out, and _TEL (M-1)
When the busy tone is received, the busy tone is detected by the orderer output, and the subscriber number of the final registered subscriber T _EL M is taken out.

The _TEL M dial signal is output to make a call to the calling side exchange to secure a loop for the called side exchange.
_{When the} line is connected because the ELM is busy, the called exchange detects busy and the calling exchange sends a busy tone to the calling terminal. When the calling terminal detects the output of the busy tone, the mailbox number of T _EL 1 is taken out.

When a mail box dial signal tone is transmitted from the calling side terminal, the calling signal reaches the called side exchange through the calling side exchange and activates the mailbox. In order to inquire the subscriber number of the mailbox invoker from the called exchange, voice guidance is sent to the calling terminal. The calling terminal listens to the voice guidance and notifies the calling party's subscriber number (using a dial button).

When the dial pulse is obtained by the called exchange, the registration guidance is transmitted to the calling terminal by voice guidance. Upon hearing the registration guidance, the subscriber speaks the message content. Record the call contents on the called exchange. When the content of the message ends, the message end operation (using the dial button) is performed. A dial pulse is sent to the called exchange to receive a recording end operation. The call ends on-hook by the calling subscriber.

Next, when listening to the recorded message in the mailbox, when the called terminal T _EL 1 goes off-hook, the called exchange starts up and sends a dial tone. When the dial tone is heard at the called terminal and the mailbox number is pressed, a dial pulse is sent to the called exchange to activate the mailbox. When the number of emails in the mailbox is notified by voice guidance, the called terminal confirms the number of emails,
Perform mail retrieval operation (using dial buttons).

A dial pulse is sent, and the called exchange takes out the designated mail, reproduces the mail, and sends it by voice. The called terminal listens to the contents of the mail, and when the mail ends, the call ends on hook. The called exchange terminates by opening the line to the mailbox.

[0017]

With the one-touch dial of the present invention, it is possible to avoid re-calling and to eliminate forgetting in the waiting state. Furthermore, it is possible to eliminate message leakage by using the mailbox.
