Abstract

PURPOSE:To enable a call to come to only a specific telephone terminal in a telephone terminal group where the same telephone number is assigned to telephone terminals, by preliminarily registering conditions of extension incoming and trunk line incoming in a terminating terminal table. CONSTITUTION:Port numbers(PN) of ports to which telephone terminals to which a telephone number is assigned are connected are registered in a terminating terminal management table 3a to which this telephone number is assigned, and information indicating whether telephone terminals connected to these ports permit incoming from an extension or not and whether they permit incoming from a trunk line or not are registered correspondingly to respective port numbers. In case of incoming to a multi-appearance group, a multi-appearance control part 6 selects a terminating terminal designating table 3 designated by the telephone number and checks which telephone terminal permits incoming in accordance with decision information, and only a telephone terminal 2 which permits incoming is sounded to generate an incoming call.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a method for specifying a receiving terminal in an electronic exchange that can simultaneously control receiving calls for a plurality of telephone terminals to which the same telephone number is assigned. .

(Prior Art) N-talk communication is generally performed between telephones one to one via a switchboard.

However, when considering how telephones are used, it may be desirable to be able to respond to incoming calls from a plurality of predetermined telephone terminals.

Conventionally, a multi-appearance call termination control system has been considered as a method that satisfies such requirements. This multi-appearance incoming call control assigns the same telephone number to a group of telephones housed in an exchange, and rings all of these telephones when an incoming call is received to that telephone number. When there is a response from one of these telephones, a line connection is established with that telephone.

Figure 3 shows the schematic configuration of a telephone exchange system that employs such a multi-appearance call control system.
1 is an electronic exchange, and 2 is a plurality of telephone terminals accommodated in this electronic exchange. These telephone terminals 2 are comprised of rotary telephones, bushhorn telephones, button telephones (multifunctional telephones), etc., and are connected to the boats of the exchange hall 1, respectively.

Here, the multi-appearance incoming call control is performed by, for example, assigning the same telephone number to a plurality of mutually related telephone terminals, and managing information indicating the telephone terminal 2 to which the telephone number is assigned for each telephone number. . Specifically, this management of telephone terminals involves inputting, in correspondence with a telephone number, the boat number (PN) to which the telephone terminal to which the telephone number is assigned is connected, in the multi-appearance management table 3 provided in the exchange 1. This is done by storing each.

In the example shown in FIG. 3, the boats connected to the telephone terminals to which telephone numbers @ (DN-200) are assigned from the information in the management table 3a are boat numbers (PN-11, 12, 1).
3,...In). Similarly, the information in the management table 3b shows that the port to which the telephone terminal to which the telephone number (DN=250) is assigned is connected is the port number (P N = 51.52, 53.-5n). .

It goes without saying that a separate telephone number is assigned to each telephone terminal that is not subject to multi-appearance call reception control, and the boat number to which the telephone number is connected is managed in correspondence with that telephone number.

According to the exchange 1 thus configured, by searching the above-mentioned management information according to the telephone number indicated by the incoming call, it is possible to find the boat to which the telephone terminal to which the telephone number is assigned is connected. can. By sending a bell ringing signal through the boat, the telephone terminal specified by the telephone number can be notified of the incoming call.

In particular, when an incoming call occurs to multiple telephone terminals to which the same telephone number is assigned as described above, it is possible to ring all of these telephone terminals 2 at the same time according to the information in the management table 3 mentioned above. becomes.

Incidentally, although such multi-appearance incoming call control has great advantages, it may even bring about problems in some cases.

For example, when a call arrives from an extension, it is convenient to ring multiple telephone terminals simultaneously using the multi-appearance call control described above, but when a call arrives from a central office line, it is convenient to ring multiple telephone terminals at once with the same telephone number assigned. You may want to ring only a specific terminal among the telephone terminals. In some cases, it may be better to perform reverse control for the extension calls and the calls received from the station 1a.

However, as mentioned above, conventional multi-appearance call control only manages telephone terminals to which the same telephone number has been assigned, and therefore it is not possible to ring only a specific telephone terminal among them.

(Problems to be Solved by the Invention) In this way, in the conventional multi-appearance call control system, incoming calls are sent only to a specific telephone terminal among multiple telephone terminals to which the same telephone number is assigned. There was a problem that it could not be generated.

The present invention has been made in consideration of these circumstances, and its purpose is to take advantage of the advantages of multi-appearance incoming call control while also allowing calls to be sent to only a specific telephone terminal among telephone terminals to which the same telephone number is assigned. An object of the present invention is to provide an incoming call control method that can cause incoming calls.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides information on whether or not to permit incoming calls from an extension for each telephone terminal in a group of telephone terminals to which the same telephone number is assigned; Information on whether or not to permit incoming calls from the central office line is registered in advance in the receiving terminal management table, and when a call is received at the above telephone number, the above mentioned receiving terminal management table is referred to and the telephone to which the call should be received is selected. It is designed to selectively control terminals. Further, the receiving terminal management table is used to select and control the receiving telephone terminal in response to an incoming call from a central office line or an extension.

(Operation) According to the present invention, when an incoming call occurs to a group of telephone terminals to which the same telephone number is assigned, it is determined whether the incoming call is from an extension or a central office line. . Then, according to the result of this determination, the receiving terminal designation table is referred to to find out which telephone terminal among the above-mentioned telephone terminal group is permitted to receive the call.

Based on the results of this investigation, only telephone terminals that are allowed to receive calls from the corresponding telephone number will be ringed.

Therefore, by registering the incoming call conditions in the incoming terminal table in advance for incoming calls from extensions and incoming calls from the office WA, the
An incoming call can be made only to a specific telephone terminal in a group of telephone terminals to which the same telephone number has been assigned.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of a telephone exchange system according to an embodiment.

The same parts as those of the conventional system shown in FIG. 3 will be described with the same reference numerals.

The feature of this system is that each telephone terminal records incoming calls from extensions in the incoming terminal management table 3 that manages telephone terminals 2 to which the same telephone number is assigned (the boat number to which the telephone terminal 2 is connected). Information on whether to permit or deny,
In addition, information on whether or not to permit or deny incoming calls from central office lines is also registered.

That is, as illustrated in FIG.
The boat numbers (PN') of the boats to which the telephone terminals assigned the telephone numbers are connected are registered in the incoming terminal management table 3a to which the telephone numbers 00) are assigned, and
Information on whether or not the telephone terminal connected to the boat allows incoming calls from extension lines (Yes, No), and information on whether or not to allow incoming calls from central office lines (Yes, No) for each of the above. The incoming terminal table 3a is configured so that boat numbers can be registered in correspondence with each other.

It goes without saying that other called terminal tables, including the called terminal management table 3b to which the telephone number (DN-250) is assigned, are similarly configured.

Here, in FIG. 1, 5 is a switching control section of the exchange 1, and 6 is a multi-appearance control section. The exchange control unit 5 controls incoming telephone calls through the exchange 1fil, controls outgoing calls, and controls line connections. Furthermore, the multi-appearance control section 6 controls incoming calls occurring at a plurality of telephone terminals to which the same telephone number is assigned.

FIG. 2 shows the processing procedure for multi-appearance call termination control in the switching system configured as described above.

Now, when an incoming call is received at the exchange 1 (step a), the exchange control unit 5 first sets the telephone number of the incoming call to a group of telephone terminals (multi-appearance group) in which the same telephone number is assigned to multiple telephone terminals. It is determined whether or not it is for. In the case of an incoming call to a multi-appearance group, the exchange control section 5 determines whether the incoming call is from an extension line or a central office line.

Thus, the multi-appearance control unit 6 receives information on the telephone number specifying the multi-appearance group from the exchange control unit 5, and also determines whether the incoming call is from an extension or a central office line. Information is being received. Then, the multi-appearance control unit 6 selects the receiving terminal designation table 3 specified by the above-mentioned telephone number (step b), and determines which telephone terminal is allowed to receive the call based on the judgment information diameter from this receiving terminal designation table 3. (steps c, d, e).

In other words, in order to determine whether the incoming call is from an extension or a central office line, step C) checks the permission information for receiving an extension call or the permission for receiving a central office line call. (Steps d, e).

According to the results of this investigation, the multi-appearance control unit 6 rings only those telephone terminals 2 that are permitted to receive calls, thereby generating an incoming call (steps f, Q>).

Specifically, when there is an incoming call indicated by the telephone number (DN-200) from an extension, the multi-appearance control unit 6
is the boat number (PN-1) from the receiving terminal specification table 3a.
It is learned that the telephone terminals connected to the boat 1, PN-13, etc. are permitted to receive calls, and the bells of these telephone terminals ring all at once. Further, if this incoming call is from a central office line, the boat number (P N = it.

PN-12, .

As a result, only a specific telephone terminal among a group of telephone terminals to which the same telephone number is assigned is selectively ringed according to the incoming call condition.

In this way, according to this system, for each telephone terminal in a group of telephone terminals to which the same telephone number is assigned, information on whether or not to allow incoming calls from an extension and whether or not to permit incoming calls from a central office line is provided. By simply registering this information in the receiving terminal management table 3 in advance, it becomes possible to selectively control the telephone terminal 2 to receive the call.

Especially in response to incoming calls from the station or from extensions,
It becomes possible to selectively control the incoming telephone terminal.

Therefore, it is possible to ring only a specific telephone terminal depending on the mode of incoming calls, so that responses to incoming calls can be made smoother and business operations can be carried out more efficiently.

Note that the present invention is not limited to the embodiments described above.

Here, information indicating whether or not to permit incoming calls is registered in the incoming terminal designation table, but information indicating whether to deny incoming calls may also be registered. Further, the above-described incoming call selection control may be performed only for incoming calls from extension lines or from central office lines. Furthermore, the number of telephone terminals to which the same telephone number is assigned and the number of telephone terminal groups (multi-appearance groups) to which incoming calls are controlled may be determined according to the specifications of the exchange system. In short, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, while taking advantage of the advantages of conventional multi-appearance incoming call control, it is possible to control incoming calls only to a specific telephone terminal among a group of telephone terminals to which the same telephone number is assigned. The bell can be selectively rung depending on the
Great practical effects can be achieved, such as the ability to provide effective incoming call services depending on the type of telephone usage.
