Abstract

PURPOSE:To improve the performance of service to a subscriber terminal by informing the state of service from a service device to the subscriber terminal utilizing the service device and decreasing useless processing in the service device to improve the utilizing efficiency. CONSTITUTION:A main memory 102 of the service device 4 corresponds a subscriber number executing the service to an addressed subscriber number and stores it as an address number table. In case of a subscriber 2 requests a service to a subscriber 1, the subscriber 2 is connected to the service device 4 from an exchange 3 and the number of the subscriber 1 is stored in the address number table as the address terminal number already. Since the same address number is detected in this case, the service state of the service device 4 is informed to the subscriber 1. That is, a central processing unit 9 gives a command to a message informing section 7 with the reception of the service state and the information representing the service state is informed to the calling subscriber 1 via an exchange switch section 6, an IF circuit 5, a line 11 and the exchange 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a service status notification method, more specifically,
The present invention relates to a service status notification method for notifying a user of the service status of a service device and efficiently using the service device in a switching system that accommodates and interconnects subscriber terminals and service devices.

Prior Art and Problems FIG. 1 is a diagram showing a connection configuration of an example of a telephone switching system equipped with a service device according to the prior art. In the figure, 1 and 2 are subscriber terminals such as telephones, 6 is a switchboard,
Reference numeral 4 denotes a service device that provides a message notification service in which, for example, a specified format message prepared in the device is later sent to a destination subscriber terminal in response to a transmission request from a subscriber terminal.

Assume that the subscriber terminal 2 is currently in a talking state. Here, when another subscriber terminal 1 makes a call to subscriber terminal 2, exchange a! 6, as is well known, notifies the calling subscriber terminal 1 that the called subscriber terminal 2 is busy (busy transmission).

When the calling subscriber 1 wishes to leave a message for the called subscriber, the calling subscriber 1 requests the service of the service device 4 and calls the service device 4 again. Exchange machine 6
connects the subscriber terminal 1 and the service device 4. The subscriber terminal 1 sends information such as the destination subscriber terminal 20 number to which the message should be sent, conditions for sending the message, and the standard message number to be sent, according to a prearranged procedure between the subscriber terminal 1 and the service device 4. do. Service family w4
receives and stores the above information, automatically calls the exchange B according to the sending conditions, and calls the service device 4 to the subscriber terminal 2 via the exchange 6 using the already memorized subscriber terminal 20 number. Connect, play and send a standard message (voice) from the specified number. Subscriber terminal 2 receives the standard message from subscriber terminal 1 described above.

In the above, the subscriber terminals (1, 2, etc.) are configured so that they can each freely use the service device 4. Therefore, two subscriber terminals may call the service device 4 at the same time and mutually request message notification service, that is, the service devices may be used overlappingly.

Even though there is a subscriber terminal 2 that is already connected to the service device and is executing a message notification service with subscriber terminal 1 as the destination, subscriber terminal 1 sends a message destined to subscriber terminal 2 at the same time. There may be cases where a notification service is requested. According to the conventional technology, at this time as well, the service device 4 received requests from the subscriber terminals 1 and 2 separately and provided independent services.

To explain in more detail, if subscriber terminal 1 makes a call to subscriber terminal 2 while subscriber terminal 2 is busy, the exchange will notify subscriber terminal 1 that subscriber terminal 2 is busy. Notice. When the subscriber terminal 1 calls the service device 4 to leave a message for the subscriber terminal 2, the exchange 3 connects the subscriber terminal 1 and the service device 4. The subscriber terminal 1 requests the subscriber terminal 2 to send a fixed message according to the procedure agreed upon in advance with the service device 4. In this state, when subscriber terminal 2 ends the call and makes a new call to subscriber terminal 1, exchange 6 notifies subscriber terminal 2 that subscriber terminal 1 is busy. The subscriber terminal 2 calls the service device 4 to leave a message for the subscriber terminal 1.

The exchange 6 connects the subscriber terminal 2 and the service device 4. The subscriber terminal 2 requests the subscriber terminal 1 to send a fixed message according to a procedure agreed upon in advance with the service device 4. The subscriber terminal 1 and the subscriber terminal/terminal 2 are disconnected when the operation '' is completed. The service group w4 then automatically calls the subscriber terminal 2, and after establishing a connection state, notifies the subscriber terminal 2 of a fixed message. Similarly, the subscriber terminal 1 is notified of the °C standard message.

As shown in the example above, if the service group W4 is providing services to subscriber terminal 1 and subscriber terminal 2 at a certain point in time, with each of them serving as the destination, after both parties finish their call,
The service device 4 newly provides subscriber terminal 1 and subscriber terminal 2.
You must call and notify the message.

According to the conventional technology, the service devices are configured to process each service request independently, so in reality, the service devices 4 as in the above example are redundantly used for the same purpose. There is a problem in that the usage efficiency of the service equipment decreases, and the service to the subscriber terminals also deteriorates due to wasteful use.

OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of the above-mentioned conventional techniques and eliminates wasteful processing in the service device by notifying the service status from the service device to the subscriber terminal using the service device. The purpose is to increase usage efficiency by reducing the amount of data used, and to improve serviceability for subscriber terminals.

Examples of the invention Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a connection configuration diagram of an example of an exchange system implementing the present invention. In the figure, 1 and 2 are subscriber terminals (only two of the plurality of terminals are shown), 3 is an exchange, and 4 is a service device. In the service device 4, 5 and 5' are interface sections, 6 is an exchange switch section, 7 is a message notification section, B is a PB dial signal receiving section, 9 is a central processing unit, and 10 is a main memory. The device 4 is connected to the exchange 3 by a plurality of lines 11, 11'.

When the subscriber terminal 1 or 2 makes a call and dials the number for connecting the service equipment 4, the exchange 6 calls the line 11.
Alternatively, it is connected to the service device 4 via 11'.

6 and 4 are diagrams showing an example of the operation flow of the service device 4. FIG. Hereinafter, the present invention will be explained in detail using FIGS. 2, 6, and 4.

In FIGS. 6 and 4, S is a section showing the operation flow of the service device 4, and TE in FIG. 3 is a section showing the operation of the subscriber terminal.

A call is made from the first subscriber terminal 1, and [Fig. 6 Stellaf (1)
], if connected to the service device 4, step (2
), the interface circuit 5 operates and notifies the central processing unit w9 of the call origination. Next, move on to step (3),
The first (calling) subscriber terminal 1 is connected to a message notification section 7 via an exchange switch section 6 under the control of a central processing unit 9 . The operation proceeds to the next step (4), in which under the control of the central processing unit 9, the message notifying section 7 sends to the calling subscriber terminal 1 information for setting the number (of the calling party). Based on this arrangement, the first (calling) subscriber terminal 1 transmits its own number in step (5).

For example, this number is sent in the form of a PB dial signal, extracted by the interface section 5, received by the PB dial signal receiving section 8, and the received number information is sent to the central processing unit 9.
The calling subscriber terminal 10 number is accepted as the calling party number.

This service device W4 associates the number of the subscriber terminal whose service is being started and executed in the service device 4 with the number of the destination subscriber terminal to which the message is sent in accordance with this request, and specifies the main memory 10. It is stored as a destination number table in the area.

Next step (move to power, read the above destination number table in the main memory 10, and then proceed to the next step (8)
, the call received in step (6) above (
The number of the first) subscriber terminal 1 is compared with the destination number in the destination number table.

In the next step (9), it is detected whether the same number as the calling (first) subscriber terminal 1 exists in the destination number table.

Assume that the second subscriber terminal 2 is now making a service request to the first subscriber terminal 1. For example, assume that the exchange 6 is connected to the service equipment 4 via the line 11' and has already sent out the number of the first subscriber terminal 10 as the destination terminal number and stored it in the destination number table of the main memory 10.

In this case, since the same destination number is detected in step (9), the operation branches to YES and moves to step (10).
The service status of the service is notified to the first subscriber terminal 1. That is, in response to the detection result in step (9), the central processing unit 9 issues a command to the message notification unit 7, controls it, and exchanges information indicating the service status between the switch unit 6, the interface circuit 5, and the line. 11. Notify the calling (first) subscriber terminal 1 via the exchange 6. The above is an example of the operation according to the present invention.A further application example will be continued below.

Following step (10), the process moves to step α, in which the message notification unit 7 similarly sends information to the first subscriber terminal 1 to determine whether or not interconnection with the second subscriber terminal 2 is possible. do.

In step (2), the first subscriber terminal 1 responds to the above-mentioned connection availability request by, for example, transmitting a specific number of a PB dial signal. This PB dial number information is sent to the PB from the interface section 5.
It reaches the central processing unit 9 via the dial signal receiving section 8,
A response is accepted at the Stellaf wound.

The next step is to move to 4, where it is determined whether the above response indicates connection is possible or not, and if connection is possible, step (G);
Shifting to oQ, the central processing unit 9 controls the exchange unit 6 to disconnect the first subscriber terminal 1 from the message notification unit 7, and if necessary, also disconnects the second subscriber terminal 2 from the message notification unit. 7 and connected to each other via the exchange switch section 6.

Here, both the first and second subscriber terminals 1 and 2 are connected and can communicate with each other. When the telephone conversation between the first and second subscriber terminals 1 and 2 is completed, both subscriber terminals go on-hook and are disconnected [step α].

In step 4, the information on the above-mentioned disconnection operation (on-hook) is extracted from the interface units 5, 5' and reaches the central processing unit 9. In the next step (to), the central processing unit 9 The terminals are disconnected, and the numbers of subscriber terminals 1 and 2 and their corresponding destination numbers are deleted from the destination number table in the main memory 1o.

Then, the series of processing ends.

Now, if a response from the connection board is input in step CI, the process branches to No in step α→ and proceeds to step 20, and on the other hand, in step (9), the response of the calling subscriber terminal is input. When it is determined whether or not the same number as the telephone number exists in the destination number table, if the same number does not exist, the process also branches to No, and in either case, the process moves to Step 3.

The operations after step (a) are similar to conventional processing. In step four, step (9)
Based on the result that there are no identical destinations, the central processing unit 9 controls the message notification section 7 to send information to match the destination numbers to the first subscriber terminal 1. The first subscriber terminal 1 enters the destination number, for example, by means of a PB dial signal, in step Q1) according to the above-mentioned timing. In step (a), the PB dial signal is extracted by the interface section 5, and the destination number information reaches the central processing unit 9, where it is accepted.

Next, the process moves to step (to), and the central processing unit 9 associates the calling party number with the destination number and writes them into the destination number table provided in a specific area of the main memo 910. The central processing unit 9 further controls the message notification unit 7 to send information to the calling (first) subscriber terminal 1 that captures the entry of a fixed message number to be sent to the destination terminal, and the subscriber The specified fixed message number will be sent according to this. [Step (c)] This designated fixed message number is received by the PB dial signal receiving section 8 and sent to the central processing unit 9.

The central processing unit 9 stores this number as a transmission message number in a message transmission table provided in a specific area in the main memory 10 and storing message transmission request information. [To step] When this series of operations is completed, the first
The subscriber terminal 1 goes on-hook and disconnects the connection [step αη].

In step (c) (see Figure 4), the central processing unit 9 accepts the cutting in the same manner as described above, and proceeds to the next step).
, the disconnection control of the message notifying unit 7 is performed, and furthermore, the calling subscriber terminal (first subscriber terminal 1) and the service device 4
Release the connection with.

At the same time, the central processing unit 9 stores the calling (first) subscriber terminal 10 number that requested the message transmission and the corresponding destination number in the message transmission table in the main memory 10. Calling (first) subscriber terminal 10 that requested the transmission of the above message from a list of 10 destination numbers.
Delete the number and the corresponding destination number.

When the operation of step (a) is completed as described above, the calling subscriber terminal 1 is also released from the exchange 3.

Thereafter, the process moves to the next step (c), and in the service device 4, the central processing unit 9 successively updates the message transmission table in the main memory 10 according to the specified service conditions, and adds the previously recorded message destination. user terminal number (
destination number). The central processing unit 9 activates the exchange 6 via the interface section 5, sends out the number of the destination subscriber terminal, and connects thereto. Then, the message notifying section 7 is connected to the destination subscriber terminal via the exchange switch section 6, and then the message notifying section 7 is controlled to reproduce and send a fixed format message to the destination recorded therein.

When the sending is completed, the central processing unit 9 stores the main memory 1.
The number of the destination subscriber terminal (destination number) that has finished sending the message and the corresponding calling party number are deleted from the message transmission table in 0, and the series of processing is completed.

Among the steps of the above processing, the step (force or α0) is a new step added by the present invention, and these steps prevent the above-mentioned duplicate use.

In the above embodiment, in its operation flow,
That is, although the service status was notified to the first subscriber terminal 1 in step α1 of FIG. 3, in this step, the service status is notified to the second subscriber terminal 2 instead of the first subscriber terminal. Furthermore, it is also possible to notify both the first and second subscriber terminals 1 and 20 of the service status.

The present invention is not limited to the above embodiments, and various modifications are possible.

Effects of the Invention Since the present invention is configured as described above, in an exchange system in which many subscriber terminals and service devices are housed in an exchange, and the subscriber terminals can utilize the service devices, the service device By notifying subscriber terminals currently using the service of the service status of the service equipment, it is possible to avoid redundant use of the service equipment, reduce wasteful processing in the service equipment, improve usage efficiency, and improve the service efficiency of the service equipment. This has the effect of improving serviceability for terminals.
