FIG. 1A is an explanatory view showing the structure of an embodiment of the present invention, in which the present invention is applied to a remote meter reading of a propane gas cylinder for home use. In the figure, 11 is an inventory control center, 12 is a meter of a household propane gas cylinder, 13 is a communication device conforming to the PHS cordless telephone communication system, and has a PHS cordless telephone wireless communication unit and a communication control unit based on a wireless communication procedure. The communication device 13 is connected to the meter 12 by wire. Reference numeral 14 denotes a base station, which can wirelessly communicate with the communication device 13. Reference numeral 15 denotes a PHS cordless telephone network such as an ISDN communication line,
It is connected to the base station 14 by wire. 16 is a base station,
It is connected by a wire to the PHS cordless telephone network 15 and can communicate wirelessly with the inventory management center 11.

That is, when the inventory management center 11 performs meter reading of the meter 12 of a specific propane gas cylinder,
A call is made to a communication device 13 connected to the meter 12 and conforming to the PHS cordless telephone communication system. The communication device 13 receives the incoming message and, upon detecting an incoming call, requests the establishment of a link channel. When the link channel is secured, the communication device 13 establishes synchronization by a synchronization berth and establishes the link channel. Link 2 on this link channel
Is established, the control of the layer 3 is started. In layer 3,
First, the communication device 13 transmits an incoming call response message to the base station 14 by wireless communication.

Thus, base station 14 determines that there is a response to the incoming call, and starts an incoming call sequence. First, the base station 14 transmits a call setting message, and instructs a transmission request of the current value of the meter 12 in a sub-address area in the call setting message at the time of calling from the center 11,
This can be transmitted to the communication device 13 by wireless communication as a call setting message from the base station 14. In addition, it is also possible to request a report of the status of a device, a battery, and the like in the subaddress area in the call setting message at the time of calling from the center 11. FIG. 1B shows an example of a destination subaddress format when a destination subaddress is used in a subaddress area in a call setting message at the time of calling from the center 11. That is, the destination subaddress format can include digital information such as a meter value transmission request and a battery value transmission request.

Thereafter, a series of call control procedures, such as a call setting acceptance message for notifying that the call has been accepted, are taken, but a call disconnection sequence for sending a disconnection message without using an information channel without entering an information communication state. enter. The disconnection message that enters the disconnection sequence is the communication device 1 that received the call.
3 or the center 11 that has confirmed that the communication device 13 has received the call setup message upon receiving the call message.

The communication device 13 that has received the request for providing information
, Calls the center 11 and, in the reverse of the previous case, incorporates the digital information value into the sub-address area of the call setting message from the communication device 13 and sends a response, and sends a disconnection message without using the information channel. Enter the disconnection sequence. Also in this case, the disconnection message that enters the disconnection sequence can be issued from the center 11 that has received the call, or can be issued from the communication device 13 that has received the call message and has confirmed that the center 11 has received the call setup message.

When the inventory falls below a certain value or when an abnormality such as a gas leak is detected, a call is made from the communication device 13 connected to the meter 12 of the propane gas cylinder to notify the center 11 of the situation. . In this case, a link channel is established from the communication device 13, and a call setup message is transmitted after the layer 2 is established. The notification can be made by writing the detection result in the sub-address area in the call setting message. This procedure is as described above.

Since transmission and reception of the subaddress can be performed between the ISDN and the PHS, the system can be constructed by accommodating the center 11 in the ISDN.

FIG. 2 is a structural explanatory view showing another embodiment of the present invention, and is an example of a stock status investigation in which the present invention is applied to a vending machine. In the figure, 11 is an inventory management center, 1
Reference numeral 3 denotes a communication device conforming to the PHS cordless telephone communication system, and includes a PHS cordless telephone wireless communication unit and a communication control unit based on a wireless communication procedure. 13 is a communication device conforming to the PHS cordless telephone communication system, 14 is a base station,
Wireless communication with the communication device 13 is possible. Reference numeral 15 denotes a PHS cordless telephone network, which is connected to the base station 14 by wire.
Reference numeral 16 denotes a base station, which is connected to the PHS cordless telephone network 15 by wire, and is capable of wireless communication with the inventory management center 11. Reference numeral 20 denotes a vending machine, which is connected to the communication device 13 by wire. Reference numeral 21 denotes a delivery vehicle, which has a built-in center device 11 'and has the same function as the inventory management center 11.

It is important that the vending machine 20 does not create a "sold out" state, and it is desirable to detect and notify when the stock quantity falls below a certain number. For this reason, when the stock quantity reaches a predetermined quantity, the communication equipment 13 connected to the vending machine 20 sends the information to the center 11.
Make a call to. In this case, a call setup message is transmitted from the communication device 13 to the base station 14 by wireless communication, and the base station 14 transmits the call setup message via the PHS cordless telephone network 15 to the base station 16.
, And the base station 16 transmits the call setting message to the inventory management center 11 by wireless communication. At that time, the code corresponding to the product of the vending machine 20 is inserted into the sub-address included in the call setting message and the call is transmitted, so that the center 11 side “sells out”.
You can know the product name that is close to the state, and you can respond quickly. In this case, the disconnection message is transmitted without using the information channel.

Conversely, it is also possible to bring the center device 11 'into the delivery vehicle 21, make a call from the center device 11' of the delivery vehicle 21, and carry out the delivery while checking the status of each vending machine 20.

It should be noted that if a system for notifying the product name and the number of stocks at fixed time intervals is set up, not only inventory management,
You can monitor consumption trends, such as top-selling products and popular selling hours, and incorporate them into your sales strategy. This means that there is no need to collect information from all vending machines, and a call is made from the center 11 to request necessary information, and vending machine 20
The communication device 13 connected to the communication device 13 responds and responds.

As described above, wireless is used to remove wiring facilities, and packet-like communication is used to transfer a small amount of data. For this purpose, a call control signal of the PHS cordless telephone communication system is used.

When a call message is received in order to confirm that the call setup message has been notified to the communication partner, a disconnection sequence for sending a disconnection message is started. When receiving the call setting acceptance message, a disconnection message may be sent. Further, assuming that the communication device does not move, it is possible to omit the radio management and the mobility management and to immediately start the disconnection sequence upon receiving the call setting message.

According to the present invention, it is possible to easily and inexpensively ascertain the stock status of unmanned goods, although the number of target articles is small. Of course, as shown in the embodiment of the propane gas cylinder, it can be used not only for inventory management but also for remote meter reading of gas, water, electricity, and the like.

In a fixed network such as ISDN, since individual lines are installed, it is inefficient to use social capital as a communication channel having only a small amount of traffic, as a method of using social capital. Therefore, the existing base station is effectively used as a use form different from the daily call by making use of the feature of wireless.

In order to realize this, a new communication utilization form can be constructed by effectively using an existing protocol. These are based on PHS cordless telephone network communication and are compatible with ISDN.
The sub address can be used as it is. For example, the sub address information collected in the PHS cordless telephone network is
Digital information can be collected from the subaddress information via N communication lines. Further, the sub address information is collected / processed in the PHS cordless telephone network, and
It is also possible to construct a new value-added network by outputting and notifying the processing result via a fixed network such as an existing analog network.
