An embodiment of the present invention will be described with reference to FIGS. 4 and 5 and FIGS.
The mobile station apparatus according to an embodiment of the wireless communication system of the present invention transmits, in addition to functions similar to those of the prior art, when the mobile device is not connected to the mobile device connection unit of the mobile station device. In addition to being controlled so that the mobile device cannot be connected to the mobile connection device due to loss or theft, the in-vehicle device can be transmitted.

FIG. 4 is a block diagram showing an example of the configuration of the wireless communication system of the present invention. 670, 680, and 790 are mobile station devices, and 671 and 681 are on-vehicle devices. FIG. 4 shows the wireless communication system of FIG. 1 with mobile station devices 670, 680, 790 instead of mobile station devices 270, 280, 290, and on-board devices 671, 681 instead of the on-vehicle devices 271 281. Instead of the portable devices 273 and 283, portable devices 673 and 683 are added, and a management device 230 is further added.
FIG. 5 is a block diagram showing an embodiment of the configuration of the mobile station apparatus of the present invention. The difference from FIG. 2 is that in-vehicle device 671 and its control unit 65 are used instead of in-vehicle device 271 and its control unit 15.

4 and 5 also, the mobile station apparatus shares an in-vehicle device used in a vehicle such as an automobile and a portable device used outside the vehicle. When a portable device is connected to the portable device connection part connected to the in-vehicle device, the transmission operation of the portable device is prohibited and the portable device is used outside the vehicle (remove the portable device from the portable device connection part). In this case, both devices are controlled not to transmit at the same time by prohibiting the transmission operation of the in-vehicle device.
Here, even if the transmission operation is prohibited, the reception operation is possible.
However, when the portable device is lost or stolen, the in-vehicle device shifts to the in-vehicle device priority mode, and transmission is possible even when the portable device is not connected to the portable connection unit. Hereinafter, this function will be described in detail.

The management device 230 can set operating conditions of each device in the mobile station devices 270, 280,.
As in the prior art, for example, the same unique information is stored in the memory 16 of the in-vehicle device 671 and the memory 36 of the portable device 273. Additional information for distinguishing each in-vehicle device and portable device is added to the unique information.
FIG. 6 is a diagram illustrating an example of unique information stored in each memory of each mobile station apparatus registered in advance. As shown in FIG. 6, for example, when the unique information of the mobile station device 670 is “00067”, the in-vehicle device 671 adds the additional information A of the in-vehicle device 671 and stores “00067A” in the memory 16, The device 673 adds the additional information B of the portable device 673 and stores “00067B” in the memory 36.

FIG. 7 is a diagram showing an example of the setting contents of the operating conditions of the mobile station device registered in the memory (not shown) of the management device 230. FIG. 7 is a diagram showing the setting contents of the transmission operation conditions of the in-vehicle device and the portable device of each mobile station in the state shown in FIG.
In FIG. 7, since the mobile device 673 is connected to the mobile connection unit 672 in the mobile station terminal 670, the in-vehicle device 671 is “operation permitted” and the mobile device 673 is “operation prohibited”. Further, since the mobile device 683 is removed from the mobile connection unit 682 in the mobile station terminal 680, the setting contents are “operation prohibited” for the in-vehicle device 671 and “operation prohibited” for the mobile device 683.

For example, it is assumed that the portable device 683 (unique information + additional information: “00068B”) of the mobile station device 680 shown in FIG. 4 is lost or stolen.
Then, when the lost or stolen information is notified from the mobile station device 680 to the management device 203, the management device 230 is configured so that the portable device 683 of the mobile station device 680 that has been lost or stolen is not used. As shown in FIG. 8, the mobile device 683 of the mobile station device 680 is set to operation prohibition, while the operation prohibition of the in-vehicle device 681 is released (operation is permitted). Then, a signal (operation control signal) including unique information of the mobile station device 680 is sent to all the mobile station devices registered in the management device 230 via the line control device 220 and all the base station devices 240, 250, 260. Send to. Note that an instruction to transmit an operation control signal from the management device 230 is given by an operator. Further, the operation control signal may be a signal composed only of unique information of mobile station apparatus 680 or a signal including other data.
The control unit of the portable device 683 that has received the operation control signal determines whether or not the unique information included in the received signal is the same as the stored unique information, and if it is the same, prohibits its own transmission operation. At this time, it is also possible to perform control such as making an alarm sound from the speaker.

  When the portable device 683 is removed from the portable device connection unit 282 by the control unit, the in-vehicle device 681 is prohibited from transmitting. Even in that case, the receiving operation is possible. Therefore, by receiving the operation control signal transmitted from the management device 230, the in-vehicle device 681 can recognize that the portable device 683 having the same specific information as itself is set to prohibit transmission operation.

Specifically, when the in-vehicle device 681 receives the operation control signal from the management device 230, the in-vehicle device 681 determines whether the unique information included in the received signal is the same as the stored unique information. Cancel the prohibition of transmission operation.
That is, the control of the in-vehicle device 681 recognizes that the portable device 683 has been disabled from the normal operation mode (the in-vehicle device priority mode) by receiving the operation control signal including its own unique information. Recognizing this, the control unit of the in-vehicle device 681 restores its own transmission function.
The management device, the control unit of the in-vehicle device, and the control unit of the portable device are both provided with a program memory (not shown), and a program for performing the above processing operation is registered in advance.
As described above, when the portable device is lost or stolen, the management device 230 sends an operation control signal including specific information of the portable device to the line control device so that the portable device cannot transmit. The data is transmitted to all mobile station apparatuses registered in the management apparatus 230 via 220 and all base station apparatuses 240, 250, and 260. The control unit of the portable device that has received the signal prohibits the operation of the transmission unit so that the transmission function is not used. However, when a lost or stolen portable device is temporarily out of the communication area of the wireless communication system when transmitted from the management device 230, or the portable device is turned off. As described above, the operation control signal may not be received. In this case, when the portable device is turned on or used for transmission within the communication area, there is a possibility that double transmission that collides with the transmission of the in-vehicle device having the same unique information may occur.

Hereinafter, as another embodiment of the present invention, a countermeasure for preventing the double transmission will be described with reference to FIG.
In this embodiment, when the operator thinks that the portable device has returned from the outside of the communication area to the communication area, and the transmission is started, the portable device is set to always execute the all-channel scan. is there.
Further, even when the power of the portable device is turned on from off, the portable device is set so that all channel scans are always executed.

If a lost or stolen portable device is to be transmitted from outside the communication area to the communication area, all channel scanning is executed at the start of transmission. In the all channel scan, the reception electric field strength of all the set channels is measured, a base station device capable of registering a location is searched, and a location registration request is made.
For example, if the base station device capable of location registration is the base station device 250, it has returned to the area, and a location registration request is transmitted to the management device 230 via the base station device 250. The management device 230 confirms whether or not an operation control signal has been transmitted in the past to the portable device that has requested location registration by referring to a transmission history stored in a memory (not shown). If the operation control signal has been transmitted to the portable device, the transmission control signal is retransmitted without outputting the location registration permission signal.

  If the lost or stolen portable device is switched from the power-off state to the power-on state, the all-channel scan is executed at the start of transmission. Processing similar to the above is performed by the management device 230. Other system configurations are the same as those in the previous embodiment.

  According to the other embodiments described above, even when the lost or stolen portable device is out of the communication area when transmitting the operation control signal, or when the power is off. However, double transmission can be prevented.
