JP2645666B2 - Control method of wireless connection device in cordless telephone device - Google Patents

Description

Description: BACKGROUND OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a control method for a multi-zone cordless telephone device when a radio connection device supplied with power from a radio channel control device is abnormal.

(2) Prior art and its problems In a multi-zone type telephone device, when an abnormality occurs in one of the wireless connection devices interconnected by radio waves with a portable device that is in communication in each wireless service zone, these errors are reported. A method of transmitting a signal such as a return signal to a wireless connection device in which the abnormality has occurred from a wireless line control device connected to a plurality of wireless connection devices by wire is generally used.
If the wireless connection device in which the abnormality has occurred is not waiting for signal reception, those signals cannot be received, and the abnormality clearing process cannot be performed.

In a multi-zone cordless telephone device, the entire service area is wide, and since it is used by many people, the effect when an abnormality occurs is great. For this reason, a return process for returning from an abnormal state to a normal state by a simple control method is required. However, a simple control method has not yet been proposed in the prior art.

(3) Object of the Invention It is an object of the present invention to provide a method of controlling a wireless connection device in a cordless telephone device that can perform a return process for returning a failed wireless connection device to a normal state by a simple control. It is in.

(4) Configuration and Operation of the Invention In the present invention, the return process is performed by repeatedly suspending and restarting the power supply to the wireless connection device in which the abnormality has occurred.

FIG. 1 is a structural example diagram of a multi-zone type cordless telephone device. As shown in the figure, a wireless line controller 3 connected to an exchange 1 by a wire (telephone subscriber line) 2 and a wire line 4
A plurality of wireless connection devices 5 in each service zone (not shown) connected to the wireless line control device 3 and an arbitrary number of wireless connection devices 5 connected to the wireless connection device 5 in the service zone currently located by each wireless line 6 It is constituted by the portable device 7. Power is supplied from the wireless line control device 3 to the wireless connection device 5 via the wired line 4.

FIG. 2 is a flow chart showing an operation example of the wireless channel control device 3 according to the present invention.

1 and 2, while the wireless connection device 5 and the wireless line control device 3 perform sequence control such as call processing, the wireless line control device 3 detects an abnormality due to any sequence error or the like of the wireless connection device 5. When the wireless connection device 5
Stop supplying power to Then, after a predetermined time (after timeout) set in the power supply start timer in advance, the wireless channel control device 3 restarts power supply to the wireless connection device 5.
Once the power is turned off and the power is turned on after a lapse of a predetermined time, the wireless connection device 5 performs an initial start-up operation (initialization → restart). In the case of a sequence error or the like, the abnormality is canceled and the operation returns to the normal operation.

When the abnormality of the wireless connection device 5 is not cleared by the initialization by one power-on, the wireless line control device 3 repeats the process of stopping and starting the power supply a predetermined number of times, for example, about 3 to 5 times. If not canceled, the wireless connection device 5 in which the abnormality has occurred is registered in the wireless line control device 3 as an abnormality.

(5) Effect of the Invention According to the present invention, when an abnormality related to sequence control or the like occurs in the wireless connection device, the abnormality is canceled by a simple process without exchanging a return signal or the like, so that the practical effect is remarkable.
