Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system cordless telephone device which can be used by a wireless terminal device in a plurality of wireless areas.

[0002]

2. Description of the Related Art Conventionally, in this type of system cordless telephone device, a user can make a call while moving by using a cordless telephone (hereinafter referred to as a cordless handset) which is a wireless terminal device. And
If the reception level of the cordless cordless handset drops during a call,
The user can move to an area with a good reception level and make a call.

Further, in a system cordless telephone device equipped with a wireless zone switching device, the cordless handset is temporarily moved into the area covered by the system, or the holding function is manually operated. If the call is put on hold by moving to a region where the reception level is good and the call is answered again, the call can be continued without being disconnected.

Further, the cordless cordless handset sounds an alarm when the battery level is low during a call to notify the user of the fact. However, as a countermeasure, the user manually holds the cordless cordless handset. , The battery can be replaced without disconnecting the call.

Even in the conventional system cordless telephone apparatus configured as described above, even if the reception level deteriorates during a call or the battery level decreases, it is possible to immediately move to an area with a good reception level. If you manually put the call on hold, you can avoid disconnecting the call.

[0006]

However, in the above-mentioned conventional system cordless telephone device, if the user suddenly enters a shielded area where the reception level is low while moving, it becomes uncertain to operate the wireless zone switching device. However, there was a problem that the call was disconnected when the operation method for holding the call was unknown.

Further, the one-sided hold of the call by the hold operation on the cordless handset has a problem that it makes the calling party who does not know the reason for holding the call very uncomfortable. .

The present invention has been made in view of the above problems, and a first object of the present invention is to make a call partner even if the reception level or the battery level decreases during a call. It is an object of the present invention to provide a system cordless telephone device that can automatically put a call on hold with a party.

A second object of the present invention is to provide a system cordless telephone device which can prevent the other party from feeling uncomfortable due to unilateral holding.

[0010]

In order to achieve the above first object, the present invention provides a main device for controlling connection between a terminal device and a wireless connection device by a wired transmission path, and a wireless connection device and a wireless communication path. A system cordless telephone device having a wireless terminal device to be formed, wherein the wireless connection device comprises:
When the wireless terminal device is in a call, the reception level deterioration notifying means for detecting that the reception level of the radio wave transmitted from the wireless terminal device is below a certain level and sending a deterioration notification signal, The main device is provided with a control means that receives the deterioration notification signal, puts the other terminal device in communication with the wireless terminal device on hold, and disconnects the call of the wireless terminal device. Further, the control means is provided with a hold response means for connecting the other party terminal device to the other party terminal device when there is an incoming call to the other party terminal device which is on hold.

Further, in order to achieve the above-mentioned second object, the present invention is provided with a connecting means for connecting a message sending means for sending a message indicating a reason for holding to the terminal device on the other end of the hold, in the control means. It is a thing.

[0012]

With this configuration, the reception level deterioration notifying means detects when the reception level of the wireless terminal device is low or the battery level is low during a call, and sends a deterioration notification signal to the control means. Thus, the other terminal device is automatically put on hold to avoid disconnection of the call.

Then, the user moves the wireless terminal device whose call has been disconnected to an area having a good reception level of radio waves or selects another terminal device having a good reception level, and then the hold response means. By activating, the wireless terminal device or another selected terminal device can be connected to the on-hold partner terminal device and the call can be resumed.

Furthermore, the message sending means and the connecting means can notify the terminal device on hold of the fact that the terminal device is on hold.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a cordless telephone device of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the outline of an embodiment of a system cordless telephone device of the present invention.

In FIG. 1, a system cordless telephone device includes a plurality of cordless telephones 1 (hereinafter referred to as cordless cordless handsets) which are wireless terminal devices, and the cordless cordless handset 1.
And a terminal device having a plurality of extension telephones 3 and the like, and a main device 4 for controlling the system cordless telephone device. Then, the main device 4 includes a talkie sending device 6 which is a message sending means for sending a hold reason message and the like, the extension telephone 3 and the wireless connection device 2, and a central control device 5 which is a controlling means which will be described later. It has a main switch 7 which is switch-connected by.

Further, the wireless connection device 2 is provided with a reception level deterioration notifying means 8 which detects a decrease in the reception level, for example, deterioration of the electric field strength of the radio wave below a certain level and sends out a deterioration notification signal. .

Further, when the central control unit 5 receives the deterioration notification signal, it terminates the cordless cordless handset 1 in which the electric field strength has deteriorated, and puts the extension telephone 3 which is the other terminal device on hold. To the call holding means 9 and the extension telephone 3 in the hold state, a re-response from the cordless handset 1 after moving to a good reception level, or another cordless handset 1 having another good reception level And extension telephone 3
Hold response means 1 for canceling the hold state by a response from
0, and the extension telephone 3 which is the other party of the call is put on hold in accordance with the deterioration notification signal, and at the same time, the talkie transmitting device 6 is selected to connect the extension telephone 3 which is the other party's terminal device and the talkie transmitting device 6. And a talkie connecting means 11 which is a connecting means.
