DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private telephone system used in a company or the like, and more particularly to a private telephone system that accommodates a cordless terminal in the system.

[0002]

2. Description of the Related Art Conventionally, as a private telephone system, for example, as shown in FIG.
ate Branch Exchange) 11 and a multi-function telephone (MKT;
Wired terminal 1 such as Multi-Key Telephone) or analog telephone
2, 13,..., Cordless terminals (PS; Personal Station) 14, 15,..., And a connection device (CS; Cell Station) compliant with RCR STD-28, which is a standard of the radio wave industry (ARIB). 16). .. Can be communicated only in a predetermined area where radio waves from the CS 16 reach, that is, in a home area.

[0003] In recent years, some of such private telephone systems have a secretary telephone service function. The secretary telephone service function is to configure the same multi-station group with several terminals in the system, and when there is an incoming call to any of the terminals in this group, the incoming call is displayed on the other terminals in the group. This function allows another terminal to make a proxy response, or allows another terminal in a group to be called with a single touch using a DSS (Direct Station Selection) key. This means that, for example, in a company, each terminal used by a company executive and its secretary constitutes the same multi-station group,
When an incoming call arrives at a company executive, the secretary presses the DSS key to perform a proxy response.

Normally, in a private telephone system having a secretary telephone service function, when using the secretary telephone service function, the same multi-station group is formed by the wired terminals 12, 13... In the system.
The same multi-station group may be configured to include 4, 15... In this case, only when the PSs 14, 15,... Are in the home area, these PSs 14, 15,.
., The wired terminals 12, 13,...

[0005]

However, in the above private telephone system, when the PSs 14, 15,... Move out of the home area, incoming calls to the PSs 14, 15,. You will not be able to make a proxy response. For example, when a company executive who carries a certain PS 14 moves out of the home area, even if there is an incoming call to the PS 14, the secretary of the company executive may perform a proxy response on the wired terminals 12, 13,. I can no longer do it. This is PS1
This problem does not occur if 4, 15,... Are used only in the home area. However, in this case, the features of the PSs 14, 15,.

Therefore, the present invention provides a private telephone system that can use a secretary telephone service function even when a PS is outside a home area when the same multi-station group including a PS is formed. The purpose is to provide.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a private telephone system devised to achieve the above object, comprising: a cordless terminal capable of making calls only within a predetermined area; An exchange that manages incoming calls to the cordless terminal and the wired terminal, wherein the cordless terminal designates a wired terminal that makes a proxy response to the incoming call to the cordless terminal, and notifies the exchange of this. Registering means for storing the identification number of the wired terminal specified by the notification when the exchange receives a notification from the registration means, and when the cordless terminal is out of a predetermined area. When there is an incoming call to the cordless terminal, incoming call control means for making a proxy response to the incoming call to the wired terminal whose identification number is stored in the storage means is provided. It is characterized in that it has been.

[0008] According to the private telephone system having the above-mentioned configuration, when the cordless terminal registration means receives designation and notification of a wired terminal for making a proxy response to an incoming call to the cordless terminal, the storage means of the exchange specifies the designation by the notice. The stored identification number of the wired terminal, for example, an extension number is stored. Thereafter, if there is an incoming call to the cordless terminal, and if the cordless terminal is out of the predetermined area at that time, the incoming call control means of the exchange exchanges the incoming call to the cordless terminal, and the storage means outputs the identification number. Is made to the wireline terminal storing the proxy response. Therefore, in this private telephone system, even if the cordless terminal is outside the predetermined area, the proxy response can be made by the wired terminal in the system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A private telephone system according to the present invention will be described below with reference to the drawings. FIG. 1 is a sequence chart of an operation example in the private telephone system of the present embodiment, and FIG. 2 is a system configuration diagram of the private telephone system in the present embodiment. However, here, the same components as those in the above-described conventional example (see FIG. 3) are given the same reference numerals, and description thereof will be omitted.

[0010] The private telephone system according to the present embodiment has a PS
1, PBX2, MKT (wired terminal) 12, 13,...
And CS16. In this private telephone system, it is assumed that the same multi-station group is constituted by PS1 and MKTs 12, 13,...

The PS 1 can communicate only in a home area where radio waves from the CS 16 reach. However,
In this PS1, a temporary secretary is registered with a special number. Temporary secretary registration means that MKTs 12, 13,... That make a proxy response to an incoming call to PS1 are registered in PBX2 in advance. In other words, PS1 for temporary secretary registration
Has a function as a registration means in the present invention.

The PBX 2 is composed of PS1, MKT12,13 ...
Management of incoming calls to PS1, MKT12,13 ...
External line connection, internal line connection, and the like. However, the PBX 2 has a function as a storage unit and an incoming call control unit in the present invention. That is, this P
The BX2 stores the extension numbers of the MKTs 12, 13,... Designated by the temporary secretary registration from the PS1 with the extension information (DNIN) for the PS1 stored in the PBX2 in advance.
The temporary secretary registration area in F) is stored. Then, when there is an incoming call to PS1 after the temporary secretary registration, this P
If S1 is not in the home area, the incoming call is made to the MKTs 12, 13,... In the PBX 2, when the PS 1 returns to the home area, the extension number stored in the temporary secretary registration area in the DNINF for the PS 1 is deleted by the location registration by the PS 1 at that time.

Next, an example of the operation when the PS 1 moves out of the home area in the private telephone system having such a configuration will be described with reference to the sequence chart of FIG. However, here, the case where PS1 is a terminal used by a company executive will be described as an example.

When the company executive moves out of the home area while carrying the PS1, the company executive performs a temporary secretary registration from PS1 with a special number. When the temporary secretary registration is performed by the company executive, the PS1 assigns the extension number designated by the temporary secretary registration, for example, the extension number of the MKT 12, to the CS16.
(Step 101; hereinafter, step is abbreviated as S). When the extension number of MKT12 is designated from PS1, PBX2 sets the extension number to PS1.
Is stored in the temporary secretary registration area in the DNINF (S102), and the registration is notified to PS1 (S103).

Here, when there is an incoming call to PS1 from outside (for example, a communication partner on a public line) (S104), PBX
2 first determines whether or not this PS1 is a cordless terminal (S105). If PS1 is a cordless terminal, PBX2 next determines whether this PS1 is outside the home area (S106). If PS1 is outside the home area, that is, not inside the home area, PBX2 will then proceed to the DNINF for PS1.
With reference to the temporary secretary registration area, it is determined whether the temporary secretary registration is performed, that is, whether the extension number is stored in the temporary secretary registration area (S10).
7).

[0016] If the extension number is stored in the temporary secretary registration area, the PBX 2 receives an incoming call to PS1.
An incoming call request is sent to the wired terminal having the extension number, for example, the MKT 12, and the MKT 12 sounds a ring tone (S108). However, the target terminals at this time are only wired terminals, and other terminals in the same multi-station group, for example, the MKT13 ...
Do not turn on the S lamp. As a result, the MKT 12 or the MKTs 13 in the same multi-station group can be used.
Then, a proxy response is made to the incoming call to PS1 (S10
9).

Thereafter, when the company executive returns to the home area with the PS1, the company executive performs location registration from PS1. When the position is registered by the executive, the PS 1 notifies the PBX 2 to that effect (S110). P
Upon receiving the notification from S1, the PBX 2 determines whether the PS 1 is in the home area (S111). P
If S1 is in the home area, PBX2 will
With reference to the temporary secretary registration area in DNINF for 1, it is determined whether or not temporary secretary registration has been performed (S
112).

Then, if the temporary secretary registration has been performed,
The PBX 2 deletes the extension number stored in the temporary secretary registration area from the temporary secretary registration area to release the temporary secretary registration (S113), and notifies PS1 that the release is OK (S114). That is, in PBX2, PS1
When the user returns to the home area, the temporary secretary registration is automatically canceled, and thereafter, a normal secretary telephone service function is provided.

As described above, according to the private telephone system of the present embodiment, if PS1 performs temporary secretary registration with PBX2, when PS1 is not in the home area,
Even if there is an incoming call to the PS1, a proxy response can be made in the MKTs 12, 13,... In the same multi-station group. Therefore, in this private telephone system, for example, when a business executive carrying the PS1 moves out of the home area, even if there is an incoming call to the PS1,
The secretary of the company executive can make a proxy response at the MKT 12, 13,.... Therefore, the secretary telephone service function can be used without deteriorating the features of PS1 such as easy carrying and movement.

The private telephone system according to the present invention may be used in the following manner. For example, when a business executive carrying the PS1 wants to avoid a response other than an emergency call during a meeting on another floor (a roaming destination or the like), the MKT in that floor is temporarily registered as a secretary and a proxy response is made with this MKT. You can also do so. However, roaming is a function that can be used even in a branch office that is away from the PS used in his or her workplace, for example.

[0021]

As described above, even if the cordless terminal moves out of the home area, the private telephone system of the present invention can register the temporary secretary in the exchange so that the incoming call to the cordless terminal can be received by the wired terminal. It is possible to respond by proxy. Therefore, in this private telephone system, the secretary telephone service function can be used without impairing the features of the cordless terminal such as easy carrying and movement.
