Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control method and apparatus for electric appliances using a cordless telephone or a mobile telephone.

[0002]

2. Description of the Related Art A simple mobile phone (personal handyphone system, hereinafter referred to as PHS) is known.
PHS is used as a wireless protocol between a wireless base station and a mobile terminal by the "Second Generation Cordless Telephone System Standard (hereinafter RCRSTD-2
8)), and uses a mobile phone outdoors, a cordless phone at home, a transceiver and a mobile terminal that plays three roles when there is a communication partner nearby or where there is no radio base station (CS). It is a system that realizes PS).

Since the owner of the PS can make and receive calls anytime and anywhere, the owner has many opportunities to wear it both outdoors and at home. Therefore, a remote control system for electric appliances using the PS is available. It is considered.

In Japanese Unexamined Patent Publication No. 7-46332, "Cordless Telephone Terminal Device", a door lock is unlocked in a portion where a self-identification information is set in a wireless message transmitted when PS starts communication with CS. Set an ID code that activates various control devices such as a device. The user operates the switch for switching between the normal mode for making a call and the ID code transmission mode for various control devices, which is provided on the PS keyboard, to enter the ID code transmission mode for the control device, and the ID provided on the keyboard. When the transmission command input switch for manually transmitting the code is operated, a wireless message including an ID code for operating the control device is transmitted from the antenna. The receivers provided in the various control devices identify the ID code in the wireless message and perform a predetermined control operation if the ID code is registered in advance.

[0005]

The conventional method has the following problems. That is, the user who has already obtained the PS needs to newly obtain the PS with the remote control function. Regarding the public subscriber number, unless a new contract is made or the PS number used until then is reassigned to a new PS, outgoing / incoming calls cannot be made outdoors, and the procedure is troublesome.

An object of the present invention is to provide a remote control system and a control device that enable remote control of electric appliances even with an existing PS.

[0007]

SUMMARY OF THE INVENTION The present invention utilizes an RCRSTD-28 inter-handset direct call protocol supported by an existing PS, which is normally a destination PS in a wireless message in the protocol. The control code for identifying the control operation of the control device is set to the destination identification code used to identify the message and the message is transmitted from the PS. The control device receives the wireless message according to the direct communication protocol between the handset units. Means and means for determining the control content of the electric appliance from the control code in the radio message, and means for controlling the electric appliance based on the determined control content.

If remote control is desired, the user changes the PS to transceiver mode and dials the control code as in a normal call. Then, the control code is set in the destination identification code portion in the wireless message and transmitted from the antenna. The control device receives the message by the wireless reception unit, identifies the control code contained therein, and controls the predetermined electric appliance when the control code is registered in advance.

As described above, even a PS having no dedicated remote control function can be remotely controlled. Moreover, as a means for transmitting the control code by wireless message, the RCR is used.
In STD-28, instead of using the calling identification code part that decides to set the PS-ID that is uniquely assigned to all produced PS, the direct dial between the handset units that sets the number dialed by the user Since the destination identification code portion of the call protocol is used, the user can freely negotiate the number and perform remote control without any problem even under the current legal system. Since the destination identification code in the wireless message is included in the first message that the PS sends to initiate the inter-slave call, the controller does not need to respond to the PS and therefore does not need the wireless message sending capability. A direct call between handset units can be made even if the location is not registered in CS, that is, remote control can be performed even in a place without CS.
