Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a control method for wireless communication performed between one base station and a plurality of mobile stations.

(Prior Art) In a conventional wireless communication system of this type, wireless communication could be freely performed between one base station and a plurality of mobile stations.

For example, in a taxi radio system, if a base station issues a call such as ``Please answer if the car is currently vacant,'' all mobile stations will respond to the call by operating their respective press 1 hakes and make a call. can be done.

For this reason, in the past, calls were often interfered with by multiple mobile stations responding at the same time, and the base station was unable to recognize all of these mobile stations that responded.

In addition, as mentioned above, in addition to optical calls from the base station, calls can also be made from mobile stations, so unnecessary calls may be made or multiple calls may overlap, making it extremely difficult to hear.
Furthermore, there were other problems such as the lack of privacy for telephone calls.

(Problems to be Solved by the Invention) In this way, with the conventional wireless communication control system, calls could be made freely, but unnecessary calls or interference between multiple calls could result in extremely slow calls. There are other problems, such as being difficult to use, not being able to recognize the person who is answering, and not having the ability to keep calls confidential.

The present invention has been made in view of the above-mentioned circumstances, and provides wireless communication control that enables quiet communication, ensures the recognition of the answering party 1, and ensures confidentiality of the call. The purpose of this article is to provide an understanding of the method.

(Structure of the Invention) (Means for Solving the Problems) In the wireless communication control method of the present invention, a base station sequentially receives and displays station numbers unique to each mobile station transmitted from each mobile station. , comprising vehicle information management means for supervising vehicle information such as empty vehicles and actual vehicles in each of the mobile stations in association with the station number;
Based on the vehicle information supervised by the vehicle information management means, a transmittable signal is transmitted to all or some selected mobile stations, and only when the transmittable signal is received. The mobile station covered by the base station can transmit a message to the base station.

(Function) In the present invention, vehicle information of a mobile station is supervised by the vehicle information management means configured to receive and display a station number transmitted from the mobile station, regardless of a call from the mobile station. That's what I do.

In addition, the base station controls transmissions from the mobile station, so that unnecessary transmissions can be regulated.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows a block diagram of an embodiment of a wireless communication system 7 according to the present invention, in which one base station 1 and a plurality of mobile stations 2 are connected via wireless lines.

Among these, the base station 1 includes a control section 10 consisting of a microcomputer unit, a radio section 11 controlled by the control section 10,
The device includes a press switch 12, a speaker 13, a keyboard 14, and a display section 15.

Similarly, the mobile station 2 also has a control section 2 consisting of a microcomputer unit.
0, a wireless section 21 controlled by the control section 20, a press 1-one switch 22, a supino J23, and a vehicle information input switch 24.

The communication operation of the wireless communication system having such a configuration is shown in FIGS. 2 and 3, respectively, for the mobile station 2 and the base station 1.
The flowchart shown in the figure is performed by a combination of operations as shown in .

First, the operation of the mobile station 2 will be explained with reference to FIG.

First, when making a call from the mobile station 2, turn on the breath talk switch 22 (step 100), and transmit the station number of the own station from the radio section 21 to the base station 1 under the control of the control section 20 (step 101). .

Furthermore, in the state where the mobile station 2 is not performing the calling operation as described above, the mobile station 2 determines whether or not a transmittable signal has been received from the base station 1 (step 102).

If it is determined in step 102 that a transmittable signal is not received, the mobile station 2 then determines whether a transmittable signal has been received from the base station 1 (step 10).
3) If the transmission prohibition signal is not received, normal operation is resumed.

Further, in the judgment in step 103, if the transmission-unable signal is received, the mobile station 2 makes the speaker 23 sound to notify the operator of the arrival of the transmission-unavailable signal.

Next, the mobile station 2 determines whether the received transmission-disabled signal for its own station is a request for a response from the mobile station 2, such as a call saying "Please respond if the car is currently empty." (Step 104).

In the determination at step 104, if the transmission impossible signal is not a response request, the mobile station 2 promptly returns to normal operation.

Further, in the judgment in step 104, if the transmission-unable signal is a response request, the mobile station 2 subsequently transmits a response signal corresponding to the transmission-unavailable signal by, for example, operating the vehicle information input switch 24. Step 105)
, and then resume normal operation.

On the other hand, if it is determined by step 102 that a transmittable signal has been received, the mobile station 2 sounds the speaker 23 in the same manner as described above to notify the operator of the arrival of the transmittable signal.

Subsequently, the mobile station 2 determines whether the received ready-to-send signal for its own station is a response request or not (step 106).
, if it is a response request, a response signal corresponding to the transmittable signal is transmitted (step 107).

Thereafter, the mobile station 2 turns on the breath talk switch 22 as necessary (step 108), and can perform transmission (sending) to the base station 1 (step 109).
.

The mobile station 2, which is now in a state where it can transmit a call, receives a transmission-disabled signal (end signal) from the base station 1, or determines whether a transmission-disabled state has been established as a certain period of time has elapsed. At step 110), normal operation is resumed once the transmission-disabled state is established.

Next, the operation of the base station 1 will be explained with reference to FIG.

First, when the base station 1 receives the station number corresponding to each station transmitted from each mobile station 2 as described above in the radio section 11 (step 2
00) Under the control of the control unit 10, the speaker 13 is sounded to notify the operator of the incoming call number, and
The received station number is determined by the current status of each applicable mobile station 2 (
A call request, an empty vehicle, an actual vehicle, etc.) are displayed on the display unit 15 (step 201).

In this way, the base station 1 can collectively collect and understand the actual status of call requests, empty vehicles, actual vehicles, etc., that is, vehicle information received by each of the mobile stations 2.

Continue with base station 1. is 1. Based on the vehicle information grasped as described above, it is determined whether or not there is a request for control to be performed by the own station (step 202), and if there is a request, the station number and various control information corresponding to the content of the control are determined. It is transmitted to each mobile station 2 (step 203).

For example, when there is a request for a phone call, the base station 1 transmits the station number to the mobile station 2 that requires the phone call, and makes a call indicating that the mobile station 2 wants to make a phone call. ``In this way, I will call the mobile station 2 that requires a conversation -t-', :LT, I, it! I7
1"1" G.

Separate, other than group, other than individual, etc. can be freely set.

Furthermore, if the base station 1 is in a state where it can make a call when it should respond with nb to the request for a request from the mobile station 2, the base station 1 transmits a transmission ready signal to the corresponding mobile station 2, Also, if it is not possible to make a call, it will send a transmission impossible signal.

Here, the state in which a call cannot be made includes a case where the base station 1 and another mobile station 2 are engaged in a call, or a case where the operator of the base station 1 is set to be absent.

Subsequently, the base station 1 determines whether a response from the mobile station 2 is necessary for the station number and control information transmitted in step 203 (step 204), and if necessary, it waits and waits until a response signal is received. A determination is made as to whether or not the message has been received (step 205).

At this time, if the response signal is not received even though there is a response request, the base station 1 indicates that the connection has failed by a method such as ringing the 3 pins 1-3 or displaying a message on the display part 15. - is notified to the operator (step 206).

Regarding the processing from step 202 to step 206, if the base station 1 is in a state where it is possible to make a call, the mobile station 2
It is also possible to automatically send back a transmission ready signal to the operator of the base station 1, and to the operator of the base station 1, a message indicating that the connection has been established and a sound indicating that the connection has been established is emitted.

During execution of such processing, after it is determined that no response is required in step 204 or after a response signal is received in step 205, the base station 1 turns on the breath talk switch 12 (step 207) and transmits the message to the mobile station 2. Transmission of necessary information (sending a call) (step 208) is executed.

[Effects of the Invention] As explained above, according to the wireless communication control method of the present invention, the vehicle information of a mobile station is supervised by the vehicle information management means comprising a microcomputer unit, regardless of the transmission from the mobile station. Therefore, even when a large number of mobile stations respond to an optical call from a base station, these mobile stations can be reliably recognized.

In addition, since the base station controls the transmission from the mobile station and restricts unnecessary transmission, it has the excellent advantage of allowing quiet and easy-to-hear communications while also ensuring sufficient confidentiality. have
