The wireless terminal control device 1 is installed at an entrance of an area where a function change of the wireless terminal 2 is required, such as a hospital or a movie theater, or at an upper portion near the entrance, and is weak enough to cover only the vicinity of the entrance. An electromagnetic wave, for example, a signal (function control signal) 6 for controlling the function of the wireless terminal 2 is constantly or periodically transmitted. The function control signal 6 is different from a normal communication control signal issued by the wireless base station 3, and there are different types of the function control signal 6. The types of the function control signal 6 include, for example, mute, transmission prohibition, and function release.

The wireless terminal 2 is, for example, a portable telephone used in a cellular telephone system, a PHS, or the like, or a portable terminal combining these. When the wireless terminal 2 is in a cover area (wireless zone) formed by the wireless base station 3 and is powered on (if it is set to a standby state), it operates as a normal operation at regular intervals. A position registration signal is transmitted to the wireless base station 3 as a communication control signal. The function of the wireless terminal 2 is changed by a function control signal 6 transmitted from the wireless terminal control device 1. For example, at the entrance of a hospital or the like, the transmission function of the wireless terminal 2 is stopped. When the wireless terminal 2 passes through the entrance again, that is, when the user exits the hospital, the function control signal 6 for releasing the function transmitted from the wireless terminal control device 1 is received. In the terminal 2, the transmission function is returned to the original callable state. In the present embodiment, the function control signal 6 and the communication control signal transmitted by the wireless terminal control device 1 are different from each other.
The same frequency as the communication control signal transmitted by the wireless base station 3 or a different frequency may be used. In addition, different signals are used for the function control signal 6 when entering and exiting the area so as to eliminate erroneous operations in changing the function. The same signal can be obtained by dedicating the exit and the exit respectively.

As shown in FIG. 2, the radio terminal 2 has an antenna 21 for normal communication, an antenna 22 for receiving the function control signal 6, a transmission function for transmitting and receiving radio waves from the antennas 21 and 22, and a reception function. A radio unit 23 having a function, a demodulation unit 24 for demodulating a received signal, a control unit 25 for identifying the type of the demodulated signal and controlling the function of each unit according to the type of the signal, and a voice under the control of the control unit 25 ,vibration,

A speaker 28 for generating a ring tone from the incoming call notifying section 26 or a demodulated received voice, a display section 29 for displaying contents such as a function change or an incoming call under the control of the control section 25, and various sections including the control section 25. And a modulation unit 32 that modulates the sound input from the microphone 31 and transfers it to the wireless unit 23. Although not shown, the wireless terminal 2 is also provided with a keypad for the user to turn on / off the power and perform a function operation. In this embodiment, since the function control signal 6 is different from the normal communication control signal, the wireless terminal 2 receives the antenna 21 used for normal communication with the wireless base station 3 and the function control signal 6 in addition to the antenna 21. And an antenna 22. In addition, the wireless terminal 2 includes a display unit 29 that displays a changed function state when a function is changed internally. Furthermore, the function control signal 6 is changed by the function control signal 6 so that the user can operate the terminal itself so as to be in the same state as when the function control signal 6 is received, and when the user exits an area where the function of the wireless terminal 2 needs to be changed. A keypad is provided so that the user can release the function even if the function cannot be restored for some reason.

The operation of the wireless communication system will be described below with reference to the flowcharts of FIGS.

First, the operation of controlling the internal function of the wireless terminal 2 to a state where transmission is impossible in a predetermined area will be described.

In this case, a function control for transmission prohibition for prohibiting the transmission to the radio terminal 2 from the radio terminal control device 1 installed at the entrance of the transmission prohibition area to the outside of the entrance at all times or at predetermined time intervals. Signal 6a is being emitted. Also, the function control signal 6b for releasing the function to release the prohibition of transmission to the wireless terminal 2 from the wireless terminal control device 1 to the inside of the transmission prohibited area constantly or at predetermined time intervals.
Is being sent.

On the other hand, as shown in FIG.
When the wireless terminal 2 is in the reception standby state (step 301), the user carrying the wireless terminal 2 passes through the entrance to enter the above-mentioned transmission prohibited area, and the wireless terminal 2 receives a radio wave through the antenna 22 through the antenna 22 (step 301). 302), transmitted from the radio unit 23 to the demodulation unit 24, demodulated and transferred to the control unit 25, and the control unit 25 identifies the type of the received signal (steps 303 and 304).

Here, if the type of the received signal is, for example, the function control signal 6a for inhibiting transmission, the control unit 25 sets the transmission function of the radio unit 23 to the transmission inhibited state, that is, the radio unit 23.
Is controlled to be in a transmission disabled state, and the transmission function of the radio unit 23 is changed to a transmission prohibited state (step 305). As a result, the transmission operation from the wireless terminal 2, that is, transmission of a location registration signal and outgoing call for a call cannot be performed. The control unit 25
Displays on the display unit 29 that the function of the wireless unit 23 has been changed to the mute state (step 306). At this time, the answering machine 27 previously provided in the wireless terminal 2 may be operated, and a control signal is transmitted from the wireless terminal 2 or the wireless terminal control device 1 so that the answering machine service is provided to the wireless base station 3. After the transmission, the transmission function of the wireless unit 23 may be stopped.

When the user is in the transmission prohibited area, the transmission function of the wireless terminal 2 does not work, so that the position registration of the wireless terminal 2 cannot be performed. In the location information, the wireless base station 3
May be able to call the wireless terminal 2.

When the wireless terminal 2 receives the call signal from the wireless base station 3, that is, the communication control signal (step 303)
The wireless terminal 2 notifies the incoming call by a vibration function or the like (step 307). However, since the transmitting function does not work and the call cannot be made, the control unit 25 of the wireless terminal 2 receives the call on the screen of the display unit 29 after the call. Only the thing is displayed (step 308). The user may be notified of the incoming call by voice. Then, the caller is notified that the communication partner is in the transmission prohibition area, and takes action by a function or service designated in advance, such as an answering machine function. However, if the wireless terminal 2 goes out of the transmission prohibited area during the call, a call can be made. Wireless terminal 2
When is not in the location where the location was last registered, the caller is notified that the call is not possible, and takes measures such as an answering machine service.

On the other hand, when the user passes through the entrance to get out of the transmission prohibited area, the wireless terminal 2 receives the function control signal 6b for releasing the function from the wireless terminal control device 1,
The control unit 25 returns the wireless unit 2 to the original function state (step 309), and the display content of the function change on the display unit 29 is deleted (step 310). If the answering machine function of the answering machine section 27 has been set, it is simultaneously released.

Subsequently, in a predetermined area, the wireless terminal 2
The operation of controlling the internal function of the device to the mute state will be described.

In this case, the wireless terminal control device 1 installed at the entrance and exit of the area where the wireless terminal 2 needs to mute the sound, so that the ringing sound (ring tone) of the wireless terminal 2 does not always sound. The function control signal 6c has been transmitted.

On the other hand, as shown in FIG.
In the reception standby state (step 401), when the user carrying the wireless terminal 2 passes through the entrance of the area and the wireless terminal 2 receives a radio wave (step 402), the control unit 25 in the wireless terminal 2 As described above, the type of the received signal is identified (step 403, step 404). When the type of the received signal is the function control signal 6c for silencing, the control unit 25 controls the incoming notification unit 26 so that no sound is emitted. In response to this control, the incoming call notification unit 26 is changed to, for example, an answering machine function or a vibrator function (vibration notification function) (step 405). Further, the control unit 25 displays on the display unit 29 that the internal function has been changed to the mute state (step 406).

If there is a normal incoming call to the wireless terminal 2 in this area, that is, if the received signal is a communication control signal (step 403), incoming call processing is performed according to the function state at that time (step 407). ). That is, the vibrator function is operated. Then, the display unit 29 of the wireless terminal 2
Is displayed (step 408), and the user is notified that there is an incoming call. Alternatively, the answering machine 27 operates to record an incoming call by the answering machine function and the contents of a message from the caller in an audio memory or the like. Then, when the user passes through the entrance again to get out of this area, the function control signal 6b for releasing the function transmitted from the wireless terminal control device 1 is received by the wireless terminal 2, and the control unit 25 sends the incoming call notification unit 26 In response to this control, the incoming call notifying section 26 cancels the mute state of the incoming call notifying function (step 409), and returns to the state in which the original ringing tone is emitted. In addition, the display content displayed on the display unit 29 is deleted by the function change (step 410). Further, if the answering machine function of the answering machine section 27 has been set, this is also canceled.

As described above, according to the wireless communication system of the first embodiment, the wireless terminal control device 1 is installed at the entrance of a place where the function of the wireless terminal 2 needs to be changed, and the wireless terminal control device 1 By transmitting a function control signal for changing the function of the wireless terminal 2, the wireless terminal 2 passing through the entrance receives the function control signal, and the wireless terminal 2 automatically changes the function to, for example, an out-of-call state or a mute state. The wireless terminal 2 without the user operating the wireless terminal 2.
Can be changed to a state suitable for the environment of the area.

Further, when the function of the wireless terminal 2 is changed, the changed function state of the wireless terminal 2 is displayed on the display unit 29, so that the user is automatically switched over to the function of the wireless terminal. Can be confirmed.

The place where the wireless terminal controller 1 can be installed is not limited to the entrance and exit of the area where the mute of the wireless terminal 2 is required. As shown in FIG. The wireless terminal control device 1 may be installed at a position where the wireless terminal control device 6b completely covers the wireless terminal control device 1.

In the first embodiment, the wireless terminal control device 1 has been described as being independent from the wireless base station 3, but has a function of transmitting a function control signal to the wireless terminal 2. If it is a wireless base station, one of the plurality of wireless base stations 3 may be used.

Next, a second embodiment of the wireless communication system of the present invention will be described.

FIG. 6 is a diagram showing a second embodiment of the wireless communication system of the present invention.

As shown in the figure, in the case of the wireless communication system of the second embodiment, the wireless terminal control device 1 is installed at the entrance of the radio wave transmission prohibited area. The function control signal 6a for prohibiting transmission from the wireless terminal 2 always or at a predetermined time interval (for example, so as to cover the entrance side of the transmission prohibition area).
Every 0.5 msec). Also, from the wireless terminal control device 1, the function control signal 6b for canceling the function of the wireless terminal 2 for canceling the call prohibition is always or at predetermined time intervals (for example, such that the function control signal 6b covers the exit side of the transmission prohibited area.
Every 0.5 msec).

When the wireless terminal 2 passes through the entrance of the transmission prohibited area, the function control signal 6a transmitted by the wireless terminal control device 1 is received by the wireless terminal 2. Then
The transmission function of the wireless unit 23 of the wireless terminal 2 is automatically changed to a transmission disabled state, so that not only the wireless communication via the wireless base station 3 but also the location registration with the wireless base station 3 cannot be performed. The function control signals 6a and 6b are transmitted from the wireless terminal control device 1 regardless of whether or not the power switch of the keypad of the wireless terminal 2 is turned on. The wireless terminal control device 1 forms small cover areas (wireless zones) 12a and 12b by transmitting weak function control signals 6a and 6b, respectively. Wireless terminal 2
The function control signal 6a is received a plurality of times. The wireless terminal 2 receives one of the function control signals 6a that can be received a plurality of times, and when the function of the wireless terminal 2 is changed by the control unit 25, a predetermined period (function change prohibition period) is set after the change.
The function cannot be changed. This function change prohibition period is desirably set to be longer than the time until a person finishes walking and passing through the cover area 12. Thus, it is possible to prevent the control unit 25 from erroneously recognizing the exit while the user is passing through the cover area 12a to the entrance and canceling the function setting. That is, once the function is changed, the function change is not effective for a while.

After the wireless terminal 2 is automatically disabled to transmit and enters the transmission prohibited area, if the time sufficiently longer than the predetermined period elapses, the wireless terminal 2 can change its function. State. Then, when the user rarely exits the transmission prohibited area and passes through the exit, the function control signal 6b for releasing the function transmitted from the wireless terminal control device 1 is transmitted.
Is received by the wireless terminal 2, the wireless terminal 2 returns to the original function state.

At this time, as when entering the entrance,
The function control signal 6b is received a plurality of times. When one of them is received and the function of the wireless terminal 2 is changed, the function of the wireless terminal 2 cannot be changed for a while after the change. Become.

This function change prohibition period is set longer than the time until the wireless terminal 2 finishes passing through the cover area 12b as in the case of entering from the entrance, thereby avoiding malfunction of the function change and preventing the transmission function from operating. To prevent that.

As described above, according to the wireless communication system of the second embodiment, the wireless terminal 2 has the coverage area 12a,
During the function change prohibition period until the passage of the function change is completed, the function change is prohibited for the function once changed, so that a malfunction at the time of the function change can be avoided. In the second embodiment, the release signal and the change signal are transmitted from different antennas to form different cover areas 12a and 12b. However, these signals may be transmitted from the same antenna. It may be a cover area. Further, the communication method of the release signal and the change signal is not limited to the present embodiment as long as it is the same method as that of the wireless terminal 2. In addition to the TDMA-TDD method such as PHS, for example, an AM method, an FM method, a frequency division method, or the like may be used.

Next, another embodiment of the present invention will be described with reference to FIGS. FIG. 7 and FIG.
This is an embodiment in which a wireless terminal capable of exchanging wireless signals of a plurality of different communication modes (hereinafter, referred to as a composite terminal) is used.

First, with reference to FIG. 7, a case will be described in which one of the communication systems of different communication forms has a limited range of radio waves, such as inside a building. .

In FIG. 7, reference numeral 15 denotes a wireless terminal (hereinafter referred to as a composite terminal) capable of exchanging wireless signals of systems having different communication modes, for example, both a cellular portable telephone system and a personal handy horn system (PHS). ). The composite terminal 15 includes an antenna 16 for receiving a radio wave of a cellular mobile phone system and an antenna 17 for receiving a PHS radio wave.
And an antenna 22 for the function control signal described above, and a display unit 29.

The composite terminal 15 is presently located in a subway station premises or the like, which is located in a communication area of a radio base station 18 forming a communication area of a PHS, for example, while it is located in a wireless area of a cellular portable telephone system. It is assumed that it is outside the communication area formed by the base station 19. The wireless terminal control device 81 is located in the subway station.

Here, when communicating with the composite terminal 15 from another source, the probability of connection is higher when using the PHS than when using the cellular mobile phone system.

In this case, the function control signal 6 transmitted from the wireless terminal control device 81 is received by the composite terminal 15, and the entire communication function of the composite terminal 15 is changed so as to transmit using the PHS. Display of function changes is displayed on display 2
9 is displayed. As a result, the composite terminal 15
Is set to perform outgoing / incoming / outgoing using the wireless base station 18. Note that, of the communication functions of the composite terminal 15, only one of the outgoing and incoming functions may be changed to use the PHS. In this case, the display unit 29 displays that only one of the outgoing and incoming functions of the composite terminal 15 has been changed.

At this time, when a caller calls the composite terminal 15 using the wireless base station 19 through the network 82 of the cellular portable telephone system, the wireless base station 19
Is not connected to the composite terminal 15 because it is outside the communication area, and usually, the cellular phone system simply informs the caller that connection is not possible.

Therefore, in the case of the present invention, the network 82 of the cellular portable telephone system and the network 83 of the PHS are connected via an exchange 84.

Then, the radio terminal controller 81 receives the communication control signal from the
Recognizes that the PHS is in a functional state, and performs wireless communication with the PHS radio base station 18.
Is instructed to inform the network 82 of the cellular mobile phone system that the composite terminal 15 is in the PHS function state. The wireless base station 18 notifies the network 82 of the cellular mobile phone system via the exchange 84 that the composite terminal 15 is in the PHS function state according to an instruction from the wireless terminal control device 81.

As a result, a certain caller can use the network 82 of the cellular mobile phone system to make the composite terminal 15
When a call is made to, the cellular mobile phone system network 82 connects to the PHS network 83 through the exchange 84 and makes a call to the composite terminal 15 through this network 83, so that the caller uses the cellular mobile phone system. Even in this case, it is possible to keep in touch with the user of the composite terminal 15 in the PHS function state.

Since the cellular mobile phone system is notified that the function of the composite terminal 15 is switching to the PHS function, the caller calls the composite terminal 15 using the cellular mobile phone system. Then, the cellular mobile phone system can notify the caller to use PHS. By notifying in this way, the caller who does not know that the communication function of the composite terminal 15 is switching to the communication function of the PHS is
5 users can be contacted.

Next, a case where the composite terminal 15 is mounted on a moving body, for example, a car or a train and moves at high speed will be described with reference to FIG.

In such a case, when communicating with the composite terminal 15 from another, the communication quality is better when using the cellular mobile phone system than when using PHS.

In this case, as shown in FIG. 8, the wireless terminal control device 81 is installed, for example, inside a car 91. Then, the function control signal 6 is transmitted from the wireless terminal control device 81 only to the inside of the automobile 91, and when the user having the composite terminal 15 enters the inside of the automobile 91, the composite terminal 15
Is changed to a communication mode of a cellular mobile phone system suitable for mobile communication. Normally, the radio wave transmitted from the radio base station 19 of the cellular mobile phone system is stronger than the radio wave transmitted from the PHS radio base station 18.

However, during movement, the PHS radio base station 18
Although the radio wave arriving from the wireless terminal may be stronger than the radio wave arriving from the wireless base station 19 of the cellular mobile phone system, the composite terminal 15 performs communication using the cellular mobile phone system as long as the terminal is in the vehicle. , And communication can be performed without deteriorating communication quality. Note that, even when the function control signal 6 is being transmitted from the wireless terminal control device 81 to the inside of the automobile 91, the user can manually change the function or release the function by operating the keypad of the composite terminal 15.

As described above, according to the wireless communication system using the composite terminal 15, the composite terminal 15 receives the function control signal transmitted by the wireless terminal control device 81, and
By changing the function of the communication mode 5 itself, it is possible to perform communication with the best communication quality according to the place where the user is located without having to judge and operate the wireless communication system used by the user. In this embodiment, the cellular communication system and the personal handy horn system (PHS) have been described as examples of systems having different communication forms. Various combinations are possible, such as a combination of a telephone system and a pager. 1 or 6
As shown in FIG. 5, by setting the communication terminal at the entrance of a certain area, the switching of the communication mode of the composite terminal 15 may be controlled at that location, and as shown in FIG. The device 81 may be installed to control the switching of the communication mode of the composite terminal 15 within the area.
