Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a plurality of individual cordless telephone devices each consisting of a main device and a wireless connection device and cordless telephones wirelessly connected by an MCA method. The present invention relates to a general cordless telephone device capable of transmitting and receiving by fixedly corresponding one-to-one with a cordless telephone and a telephone line even in a call zone.

[0002]

2. Description of the Related Art Conventionally, in a general cordless telephone device composed of a plurality of individual cordless telephone devices, the call zones of the individual cordless telephone devices may overlap each other. Since destruction may occur, in order to prevent this, different system IDs are assigned to the respective call zones of the individual cordless telephone devices.

For this reason, the cordless telephone cannot be used outside the call zone of the individual cordless telephone device to which the cordless telephone belongs, and consequently the call zone of the cordless telephone is limited to one call zone.

[0004]

According to the above-mentioned conventional technique, the call zone in which the cordless telephone can be used is limited to a specific zone. Therefore, when the integrated cordless telephone device is regarded as one system, the call cannot be made in that system. There is a problem that there are various regions.

Further, the number of call zones set for one individual cordless telephone device is limited due to the relationship between the number of control channels of the wireless line and the time required for the cordless telephone to ring when an incoming call arrives. In the past, only 4 zones could be set at maximum.

The present invention proposes to solve this problem, and in a general cordless telephone device composed of a plurality of cordless telephone devices, all cordless telephones can be used in any call zone. Moreover, it is an object to obtain an integrated cordless telephone device in which the number of call zones is not limited.

[0007]

In order to solve the above-mentioned problems, the present invention provides a general cordless telephone device accommodating a plurality of individual cordless telephone devices, which uses a telephone line such as an extension of a private branch exchange, a dial-in line, or a general office line. Connect to each of a plurality of main devices in multiple ways, assign the same system ID to a plurality of wireless connection devices and a plurality of cordless telephones connected to the plurality of main devices, and call each individual cordless telephone device. The zones are set so that they do not overlap each other.

[0008]

Since the system ID is assigned with the same code to all wireless connection devices and cordless telephones, for example, when a call-out event occurs from the cordless telephone,
The calling signal transmitted from the cordless telephone using the control channel of the wireless line can be received by the wireless connection device of any communication zone, and the telephone line is connected to all the main devices in a duplex manner. Therefore, the wireless connection device connected to the main device can be connected to any telephone line.

Therefore, regardless of which call zone the cordless telephone is in, a call can be made to the telephone line corresponding to the cordless telephone.

Further, since there is no overlap between the call zones of the plurality of individual cordless telephone devices, the calling signals are not simultaneously received by the wireless connection devices having different call zones.

In addition, when an incoming call occurs to the cordless telephone, since the telephone line is connected to all the main devices in duplicate, all the individual cordless telephone devices constituting the integrated cordless telephone device can receive the incoming call. Upon detection, each individual cordless telephone device sends an incoming call signal to the corresponding cordless telephone via the wireless connection device. In this case as well, since there is no overlap between the call zones of the individual cordless telephone devices, there is no destruction of the incoming call signal due to radio interference on the control channel, and the cordless telephone receives the incoming call signals from the multiple individual cordless telephone devices. It does not receive at the same time.

The cordless telephone receiving the incoming call signal,
An incoming call response signal is sent to the wireless connection device that is the source of the incoming call signal, the wireless channel shifts from the control channel to the call channel, the incoming signal is received by the call channel, and the cordless telephone rings the incoming call.

At this time, since there is no incoming call response signal for the incoming call signal transmitted in the individual cordless telephone device in the call zone where the corresponding cordless telephone does not exist, it is assumed that the cordless telephone is out of the area of its own call zone from the telephone line. Incoming calls are processed.

The wireless connection devices 511 to 51k, 521 to 52k, ... 5m1 to 5 in the integrated cordless telephone device 2
The same system ID is given to mk and the cordless telephones 61 to 6n.

For example, when the cordless telephone 61 exists in the call zone Z1 of the individual cordless telephone device 31,
When a call-out event occurs from the cordless telephone 61, the call-out signal transmitted from the cordless telephone 61 using the control channel of the wireless line is the call zone Z1 in the area where the cordless telephone 61 is present. The wireless connection device 511 is selected by being received by one of the wireless connection devices 511 to 51k, for example, the wireless connection device 511, and then the extension 11 of the private branch exchange 1 corresponding to the cordless telephone 61 in the main device 41. Is captured.

At this time, a plurality of individual cordless telephone devices 3
Since there is no overlap between the call zones Z1 to Zm of 1 to 3 m, other individual cordless telephone devices 32
Up to 3 m do not receive a call signal from the upper cordless telephone 61.

The above is the same when the cordless telephone 61 is present in the call zones Z2 to Zm of the other individual cordless telephone devices 32 to 3m.
