Abstract

PURPOSE:To reduce the burden of a central controller by preliminarily preventing the encounter in conversation by displaying an idle/closed state of the opposite destination area on an originating call terminal equipment before the originating call terminal transmits low-order digits when the host digits of a communication opposite party terminal number digit is received. CONSTITUTION:A host digit decision means 3 of an exchanging device S decides whether or not the host digit of the opposite party terminal number transmitted from an originating call terminal equipment 2 is received. An idle/closed extraction means 4 specifies terminal groups including the opposite party terminal by the host digits. The idle/closed state of terminal groups specified by referring to the idle/closed data of an idle/closed data preparation means 1 before receiving low-order digits is extracted. An idle/closed information notification means 5 notifies idle/closed information extracted by the idle/closed information extraction means 4 to the originating call terminal 2 and displays it on a display D.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching system capable of managing the idle/busy status of subscriber terminals, and more particularly to a terminal status notification system for displaying information regarding the terminal status notified from an exchange on the terminal.

0002

[Background Art] In recent exchange systems, service displays have become more multi-functional, and various service displays such as displaying the status of the communication destination terminal on a display installed on the terminal have become available. There is a need to further improve the user environment for subscribers.

[0003] For example, in an intra-company exchange system, multiple extension terminals installed in related department areas (hereinafter referred to as office areas) of a business office have a common code for identifying the office area. A subscriber number consisting of upper digits and lower digits for identifying each extension terminal is assigned. That is, a subscriber number such as 3310 to 3319 consisting of the first three digits 331 as the common upper digits that specify the area and the last digits 0 to 9 as the lower digits that specify each extension terminal is assigned to each extension terminal.

0004

[Problem to be Solved by the Invention] In this type of conventional switching system, even if a caller wants to receive a call to one of the extensions in the business area, the call must be made using one extension number. Because of this, it often happens when this extension is busy. The disadvantage is that during such a call, the load on the central control unit of the electronic exchange increases.

[0005] In the conventional service display, the number transmitted from the calling terminal is used to check whether the other party is free or busy based on all digit information of the extension number of the communication destination, and if the caller is busy, a message is displayed. ” was displayed on the calling terminal, but it was not possible to recognize in advance whether the communication destination was busy, and the drawback of encountering a busy state and placing a burden on the central control unit has been eliminated. It had not been done.

[0006] In the present invention, when the high-order digits of the communication destination terminal number are received from the calling party, the empty/occupied status of the terminal group in the area specified by the high-order digits is checked before transmitting the low-order digits. The purpose of this is to notify the caller of an empty terminal in advance by displaying it on the terminal, thereby avoiding a busy call and reducing the load on the central control unit.

[0007]

[Means for Solving the Problems] In the present invention, in an exchange system that can refer to and extract empty/busy data of subscriber terminals,
When receiving high-order digits that identify a certain group of terminals in a subscriber number from a calling terminal equipped with a function to display information from an exchange, the calling terminal uses the high-order digits before transmitting the lower digits. The calling terminal is notified of the vacant/occupied information of the identified terminal group.

In, S is an electronic switch. Reference numeral 1 denotes empty/busy data creation means provided in the exchange S. Reference numeral 2 denotes a calling side terminal device having a display D. 3, 4 and 5 are upper digit determination means provided in the exchange S according to the present invention;
They are an air/occupancy information extraction means and an air/occlusion information notification means. The free/busy data creation means 1, the upper digit discrimination means 3, the free/busy information extraction means 4, and the free/busy information notification means 5 are all provided in the central control unit of the exchange S.

[0009]

[Operation] Vacant/occupied data creation means 1 provided in exchange S
manages the idle/busy status of a plurality of subscriber terminals connected to the exchange S, such as whether they are currently busy or not, and creates idle/busy data.

[0010] The upper digit determination means 3 is a terminal device 2 on the calling side.
The subscriber number numeric information of the communication destination terminal is received from
31) is received.

The empty/full information extracting means 4 is the upper digit discriminating means 3.
When it is determined that the above-mentioned high-order digits have been received, the terminal group including the destination terminal is specified by the above-mentioned high-order digits, and the free/busy data created by the free/busy data creation means 1 is referred to. Then, before receiving the lower digits of the communication destination number (in the above example, the lower 1 digit 0 to 9) from the terminal device 2, empty/busy information indicating the empty/busy status of the terminal group is extracted.

The empty/busy information notification means 5 notifies the calling side terminal device 2 of the extracted empty/busy information, and displays the communication partner on the display D of the terminal device 2 before the terminal device 2 transmits the lower digits. Displays the next sky/block information.

[0013] The caller can check the empty/busy information, recognize the empty subscriber number of the communication destination before transmitting the lower digits, and transmit to the recognized empty terminal. As a result, it is possible to avoid encountering a busy call and reduce the load on the central control unit of the exchange S.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to the above-mentioned corporate extension switching system will be described below with reference to the drawings. FIG. 2 shows a functional block diagram of the exchange S and the terminal device 2 as an embodiment of the present invention, FIG. 3 is a flowchart showing the flow of processing within the exchange S, and FIG. 2 is a flowchart showing the flow of the process. In addition, FIG. 5 is a diagram showing the empty/busy status of the communication destination, FIG. 6 is a diagram showing the extension busy table 7, and FIG.
2 is a diagram showing the display status of empty/busy information on the calling side terminal device 2. FIG.

In FIG. 2, an extension idle/busy processing section 6 and an extension busy table 7 are already provided as the idle/busy data creating means 1 inside the exchange S of FIG. Further, as the upper digit discriminating means 3 in FIG. 1, a subscriber number numeric information receiving section 8 and a received digit number analysis section 9 are provided, and as the empty/busy information extraction means 4 in FIG. and a busy extension data processing section 11 are provided. Furthermore, an empty/occupied display command unit 12 is provided as the empty/occupied information notification means 5 of FIG. Furthermore, an existing processing section 13 is provided which performs existing processing as an exchange.

Inside the terminal device 2 in FIG.
and an existing processing unit 16 that performs existing processing as a terminal device.
will be provided.

The operation of the embodiment will be explained below with reference to the flowcharts of FIGS. 3 and 4. In addition, extension empty/blocked processing unit 6
detects whether the extension terminal is empty or blocked as shown in Figure 5, and
The idle/busy status of the extension terminal is managed by creating the idle/busy data with the block as 0/1 and setting it in the extension busy table 7 as shown in Figure 6 (Figures 6 and 7 are As will be described later, only the business area of the communication destination is extracted and shown).

When the subscriber number numeric information receiving unit 8 receives the subscriber number numeric information of the communication partner from the terminal device 2 on the calling side in step 20, the numeric information is passed to the received digit number analysis processing unit 9. Then, the process of determining whether the number of received digits in step 21 is the number of digits of the subscriber number of the communication partner minus 1 is performed. That is, it is determined whether the upper digit 331 specifying the aforementioned office area has been received. If it is not a high-order digit, the existing processing unit 13 performs the existing processing of step 22.

If the number of received digits is minus 1 in step 21, the number of digits in the subscriber number of the communication partner is minus 1, the free/busy information is extracted in step 23 by the free/busy display requesting section 10 and the busy extension data processing section 11. Perform processing. That is, the idle/busy display requesting unit 10 specifies the terminal group in the business area of the communication destination using the upper digits (331), and refers to the busy extension table 7 via the busy extension data processing unit 11. , by extracting the busy state of the terminal in the business area, that is, extension 10, the vacant/busy information of the business area is extracted.

The extracted vacancy/occupancy information is emptied/occupied display command unit 1
2, the calling terminal device 2 is notified as additional information, and an empty/occupied display command is issued in step 24.

In the terminal device 2 on the calling side, in step 25, the empty/occupied display command receiving unit 14 determines whether or not the empty/occupied display command has been received, and if the vacant/occupied display command has been received, then in step 26 Then, the empty/busy information display section 15 displays the air/busy information of the communication destination on the display D, and if the air/busy information has not been received, the existing processing section 16 performs existing processing in step 27.

FIG. 7 shows an example of a display when communication is made to the above-mentioned office area to which the above-mentioned extension numbers 3310 to 3319 are assigned. Display D is, for example, 20
It is possible to display numerical information in two rows, upper and lower. For example, terminals whose last digits are 0, 1, 4, 5, 7, 9 are empty, 2,
When terminals 3, 6, and 8 are busy (busy), the free/busy information sent from the free/busy display command unit 12 is 001100101.
0, and the upper digits, that is, the dial number information (upper digits) are 3.
It will be 31. In response to this information, the display D of the calling terminal device 2 displays 331 on the top row and the last digit of the empty terminal on the bottom row as shown in FIG. 7 (the number in parentheses is the last digit of the occupied terminal). .

[0023] Before pressing the final digit, the caller recognizes the vacant/occupied status of the other party using this display D, and then arbitrarily selects and presses the final digit of the vacant extension terminal, or By pressing all the digits again, you can communicate with an empty terminal before encountering a busy call.

For example, if the caller knows the location of the terminals in the business area of the communication partner, it becomes possible to communicate with the extension terminal closest to the communication partner.

It should be noted that FIGS. 2 to 7 merely show embodiments of the present invention, and the configurations of the exchange S, the terminal device 2, and the display D are not limited to those shown in the figures, and do not reflect the gist of the present invention. It may be modified as long as it does not deviate from the above.

In particular, in the embodiment, explanation has been given by taking a business area with 10 extensions as an example; however, the present invention is not limited to this; for example, by setting the lower digits to 2 digits, it is also effective for areas with even more extensions. .

[0027]

As described above, according to the present invention, before the calling party transmits the lower digits, the terminal group identified by the higher digits can be checked.
Since the busy status can be displayed on the calling terminal, the caller can arbitrarily select an empty terminal to communicate with, thereby avoiding encountering a busy terminal and reducing the load on the central control unit. can contribute to
