Abstract

PURPOSE:To obtain different service functions with the same selection signal from a terminal equipment and to obtain the same service function even from the different selection signals. CONSTITUTION:A selection class is provided for each of terminal equipments 1, 2 accommodated in a PBX 3 or the like and a service function request discrimination table of the PBX 3 is assigned to each selection class. Then a selection signal sent from a terminal equipment to the PBX 3 or the like is discriminated by the service function request discrimination table. Thus, different service functions are served by the same selection signal for each terminal equipment and the same service function is served by the different selection signals.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PBX or the like corresponding to a selection signal (dial) sent from a terminal such as a telephone housed in a private branch exchange or a key telephone device (hereinafter referred to as PBX). To identify the service features of the.

[0002]

2. Description of the Related Art Conventionally, a terminal such as a telephone housed in a PBX or the like can request an arbitrary service function possessed by the PBX or the like by sending a dial or the like as a selection signal to an accommodating source of the PBX or the like. .

[0003]

However, in the above-mentioned conventional PBX and the like, since there is only one judgment table for judging the selection signal for requesting the service function, one selection signal corresponds to one service function. There is a problem in that the service function cannot be separated by the same selection signal for each terminal that has been determined and requested for service.

Further, there is also a problem that it is necessary to secure a function that a terminal accommodated in the same PBX or the like does not want to provide as a selection number to the PBX or the like, in order for another terminal to provide the service.

The present invention solves such a conventional problem. Even if the selection signal used for service request from a terminal such as a telephone housed in a PBX is the same,
It is an object of the present invention to provide an excellent service function identification method in a PBX or the like that can request different service functions for each terminal and can request the same service function even with different selection signals.

[0006]

In order to achieve the above object, the present invention provides a selection class for determining a selection signal requesting a service function to a terminal accommodated in a PBX or the like, and further, in the PBX or the like. Then, for each of the selected classes, a service function request judgment table for deciding the service function for the selection signal sent from the terminal is prepared. As a result, even if the selection signals sent from the terminals are the same, P
In order to provide different service functions for each terminal accommodated in the BX or the like, it is possible to provide the same service function even with different selection signals.

[0007]

Therefore, according to the present invention, even if each terminal accommodated in the PBX or the like sends the same selection number, the P
The BX or the like can recognize the selected class of the terminal, determine the corresponding service function from the service function request judgment table, and can provide any service function to each terminal. Further, by sufficiently securing the service function request judgment table, it becomes possible to freely assign selection signals (numbering plan) corresponding to the service function request, and the PBX can be freely selected.
P that has flexibility for the numbering plan of users who use
BX etc. can be done.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a PBX or the like to which the method of the present invention is applied, FIG. 2 is a flow chart showing a processing procedure of a service function according to this embodiment, and FIG. 3 is a relation between a selected class of a terminal and a service function request judgment table. FIG.

In FIG. 1, 1 and 2 are terminals such as a telephone,
3 is a PBX accommodating terminals 1 and 2, 4 is a trunk line trunk,
5 is a leased line trunk.

As shown in FIG. 3, the PBX 3 has a selection class table for judging a selection signal requesting a service function from each of the terminals 1 and 2 accommodated therein, and further, in the PBX 3, A service function request determination table for determining a service function for the selection signal transmitted from the terminals 1 and 2 is provided for each selected class.

Next, the operation of this embodiment will be described with reference to FIGS. In this embodiment, station line transmission and leased line transmission normally used in PBX and the like will be described as examples of service functions. Here, the station line transmission means the terminal 1 or 2
When a call is sent from the PBX 3, it means to send some selection signal to the PBX 3 to supplement the station line trunk 4. Moreover, the private line transmission means that when the terminal 1 or 2 makes a call, some kind of selection signal is sent to the PBX 3 to supplement the private line trunk 5.

The selection classes of the terminals 1 and 2 in this embodiment are selection classes a and b, respectively, as shown in FIG.

For example, if the selection signal A is sent to the PBX 3 as a station line call request by the terminal 1 making a call (step S1), the PBX 3 recognizes the selection class a of the terminal 1 and provides a corresponding service. Function request judgment table a
Is extracted (step S2). Next, in step S3, the extracted service function request determination table a is indexed, and it is determined whether or not the service function matches the selection signal A, that is, the line transmission (step S4).

If the selection signals A do not match, the process returns to step S2. If it is determined that the selection signals A match, that is, if the transmission is the local line transmission, the process proceeds to step S5.
By executing a predetermined service function process, the operation of supplementing the central line trunk 4 is performed.

Similarly, when the terminal 2 makes a call to send the selection signal A to the PBX 3 as a leased line call request, the PBX 3 recognizes the selection class b of the terminal 2 and supports the corresponding service function. The request determination table b is extracted (step S2). Next, in step S6, the extracted service function request determination table b is indexed to determine whether the service function matches the selection signal A, that is, whether the leased line is originated (step S4). Here, if the selection signals A are determined to be coincident with each other and it is determined that the leased line is originated, the process proceeds to step S5, and the leased line trunk is captured by performing a predetermined service function process.

As described above, in the present embodiment, even if the same selection signal A is used, different service functions are used for distinguishing between the terminals 1 and 2, that is, the difference between the selection classes a and b, that is, station line transmission or leased line transmission. Can be provided.

Further, as is clear from FIG. 3, even if the selection signals A and B are different, one of the service functions of the station line transmission and the leased line transmission is determined in the terminals 1 and 2. Have an effect.

[0019]

As is apparent from the above embodiment, the present invention allows the terminals accommodated in the PBX or the like to have a selection class and a service function request judgment table corresponding to the selection class so that the same selection can be made. Even if it is a signal, the service function requested by each terminal can be provided by a PBX or the like that can be recognized as a separate service function request.

Further, it is possible to provide the PBX or the like which can be recognized as the same service function request even with different selection signals.

Further, the selection signal allocation (numbering plan) corresponding to the service function has only one side in the conventional PBX and the like, but in the present invention, since the service function request judgment table is provided in multiple sides, one PBX can be used for numbering. This has the effect that it can be applied to a PBX in which terminals are accommodated.
