FIELD OF THE INVENTION The present invention relates to wireless telephone systems, and more particularly to call forwarding displays.

[0002]

2. Description of the Related Art Conventionally, there has been known a radio telephone system including a telephone main unit connected to a telephone line and a telephone slave unit wirelessly connected to the telephone main unit.

In this radio telephone system, an upstream channel (information transmission channel from the telephone slave unit to the telephone main unit) and a downstream channel (information transmission from the telephone main unit to the telephone slave unit) having frequencies defined by the standard are provided. Channel) and
When information about a call is generated, a wireless link is established and data transmission and voice communication between the two are performed.

By the way, in a normal non-wireless key telephone system, it is known that a telephone is provided with a display for displaying absent information.
This absence display is made as follows.

That is, when the user moves from a desk to a different room in a conference or the like, a call is set to be transferred to the telephone in the conference room by the call forwarding operation of the telephone there. By doing so, the call forwarding display is displayed on his / her desk phone.

[0006]

On the other hand, also in the wireless telephone system, the following method can be considered as a method of displaying the call forwarding.

First, when a call forwarding operation from the telephone slave unit occurs, the telephone slave unit establishes a wireless link to transmit information associated with the call forwarding operation to the telephone main unit, and transmits this information to the telephone main unit. . Then, the telephone main unit establishes a wireless link to transmit the absent information to another telephone slave unit,
A method of transmitting this information and displaying the absence is conceivable.

However, as described above, since the information relating to the call forwarding is not related to the direct call, a new wireless link cannot be established and the information cannot be transmitted. It has the drawback that it is not possible to display the absence.

In order to display the absence display to the telephone subunit transferred to the absence, an automatic call is made from the telephone main unit to the telephone subunit transferred to the absence when the absence transmission operation from a certain telephone subunit occurs. Then, it is conceivable to establish a wireless link, transmit the absence transfer information, and display the absence.

However, this automatic calling system is wasteful from the standpoint of effective use of the wireless line by intentionally establishing a wireless connection and making a phone call to a telephone slave unit which is known to have been set absent by the telephone main unit. There is a drawback that there are many.

An object of the first invention relating to the present application is when an absent transfer operation of a certain wireless slave unit is performed from another wireless slave unit to a telephone main unit without causing the above-mentioned drawbacks. However, the present invention intends to provide a wireless telephone system capable of displaying a message indicating that the call has been transferred to a certain wireless slave device.

The second object of the present invention is to eliminate the presence of a certain wireless slave unit from another wireless slave unit with respect to a communication control device via the wireless master unit without causing the above-mentioned drawbacks. An object of the present invention is to provide a wireless telephone system capable of displaying an absent transfer to a certain wireless handset even when a transfer operation is performed.

[0013]

A radio telephone system according to the present invention comprises a telephone main unit and one or a plurality of telephone slave units wirelessly connected to the telephone main unit. Sets the other handset to be absent when there is an operation to transfer the other handset from the handset, and then sends the absence information after the other handset is operated. Has a means, the telephone cordless handset,
It has a means for indicating absence by the received absence information and turning on an absence lamp.

With the above configuration, when there is an absent transfer operation from a certain wireless slave device, the telephone main unit executes the absence transfer setting of another wireless slave device, and the wireless slave device which has completed the absence transfer setting is notified. Send to. After that, another wireless cordless handset performs, for example, an outside line transmission operation, etc., and when this operation ends and returns to the standby state, information indicating that the absence transfer setting is set is transmitted,
This display and the lamp display are displayed on the wireless slave set for the absence transfer setting.

Therefore, the wireless slave set for call forwarding will not establish a wireless link unless an operation relating to a call such as an outside call is performed. In this case as well, since the call forwarding is executed within the telephone main unit, the call is forwarded to the wireless handset for which the call forwarding is set, without creating a useless radio link even if an incoming call is received.
