Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone system suitable for emergency contact and a communication method therefor.

[0002]

2. Description of the Related Art For example, when an emergency patient contacts a receptionist at a hospital or the like, the person who responds hears the patient's condition in detail and transmits the information to a doctor who treats the patient. .

In this case, the information is transmitted in two steps from the emergency patient to the person who responds, and further from the person who responds to the doctor who responds. May be missing or other information may be added.

As a system for transmitting such information directly to a corresponding person, for example, Japanese Patent Application Laid-Open No. 9-27.
According to Japanese Patent No. 0874, when an emergency call is received from the second handset to the base unit during a call between the base unit and the first handset, the call path control unit holds the call of the first handset. Then, after connecting the second slave unit to the master unit, only the reception channel portion of the first slave unit is connected to the communication channel between the second slave unit and the master unit. As a result, the first slave unit can monitor the call between the second slave unit and the master unit.

[0005]

However, in the above-mentioned conventional system, when the first slave unit monitors a call between the second slave unit and the master unit, the first slave unit and the master unit Only when there is a call to and from. Therefore, the first
If there is no call between the child device and the parent device,
Monitoring by the first child device becomes impossible.

When such a system is applied to a system having a plurality of telephones, for example, it is not possible to notify all the telephones that there is an emergency call, and the above-mentioned information from the emergency patient is dealt with. There is a problem that it cannot be surely transmitted to the doctor in real time.

The present invention has been made in view of such circumstances, and provides, for example, a button telephone system and a communication method therefor capable of reliably transmitting information from an emergency patient to a corresponding doctor in real time. It allows you to do things.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

FIG. 1 is a block diagram showing an embodiment of the key telephone system of the present invention, FIG. 2 is a plan view showing the telephone terminal of FIG. 1, and FIG. 3 is an operation of the key telephone system of FIG. It is a figure for explaining.

The key telephone system shown in FIG. 1 includes a call control device A and a plurality of telephone terminals D1 to Dn.

The call control device A performs incoming call, outgoing call, transfer, call path connection, and the like. The call control device A is connected to a not-shown upper exchange system by a plurality of external lines B1 to Bn. The call control device A and the plurality of telephone terminals D1 to Dn are connected by a plurality of extensions C1 to Cn.

The telephone terminals D1 to Dn are, as shown in FIG. 2, an emergency call button DA, an emergency call display LED D-B as an emergency call indicator, a handset DC, an LCD display DD, and a dial button. Equipped with D-E.

Next, the operation of the key telephone system having such a configuration will be described.

First, as shown in (state a) of FIG. 3, it is assumed that the telephone terminal D1 uses the extension C1 to talk to the outside line B1. In this state, when the emergency call button D-A shown in FIG. 2 is pressed, the call control device A causes the telephone terminal D
Make an emergency call to 2.

The telephone terminal D2 that has received the emergency call automatically enters a call state, and a hands-free call becomes possible. Further, the call control device A connects the extension C2 connected to the telephone terminal D2 to the call path between the outside line B1 and the extension C1 connected to the telephone terminal D1.

As a result, as shown in (state b) of FIG.
It becomes possible for the telephone terminal D2 to listen to the call made at the telephone terminal D1 through the outside line B1. At this time,
The call control device A lights or blinks the emergency call display LEDs D-B of all the other telephone terminals Dn to notify all the other telephone terminals Dn that the emergency call is being made.

When any of the dial buttons DE of all other telephone terminals Dn is operated to dial a predetermined function code, the call control device A is connected to the telephone terminal Dn. The extension line Cn is connected to the call path between the outside line B1 and the extension line C1. As a result, as shown in (state c) of FIG. 3, it becomes possible for the telephone terminal Dn to listen to the call made at the telephone terminal D1 through the outside line B1.

As described above, in the present embodiment, for example , the emergency call button of the telephone terminal D1 is in operation while the outside line B1 which is the first outside line and the telephone terminal D1 which is the first telephone terminal are in a call. When D-A is pressed, the call control device A
Since an emergency call is made to D2, which is the telephone terminal of, the information from an emergency patient can be reliably transmitted to the corresponding doctor in real time.

In this embodiment, when the call control device A makes an emergency call to the telephone terminal D2, the telephone terminal D
Although the case where only 2 is automatically in the call state and the hands-free call is possible has been described, the present invention is not limited to this example, and other telephone terminals Dn are automatically in the call state, You can also enable hands-free calling.

In the present embodiment, the case where the emergency call button D-A is operated to make an emergency call has been described, but the present invention is not limited to this example, and a predetermined function code may be dialed. It is possible, and further, for example, by the extension dial, specific telephone terminals D1 to Dn
You can also make an emergency call to.

[0022]

According to key telephone systems and the communication method according to the above as the present invention, for example the first outside line and the first telephone terminal during a call, an emergency call button of the first telephone terminal When pressed, the call control device
Since an emergency call is made to the telephone terminal, it is possible to surely transmit the information from the emergency patient to the doctor corresponding to the information in real time.
