The transmission function of the mobile station is restricted.

[0005]

However, in the former case, only the transmission / reception function for emitting a strong electromagnetic wave is limited spontaneously in the portable telephone. There is a problem of forgetting to operate.

In the latter case, since a restriction request signal is transmitted from the base station, all mobile stations within a fixed service area determined by the base station are subject to transmission restriction, and the restriction range is generally limited. Because it is fixed over a wide area,
It is not suitable for restricting the control range to a relatively narrow range or for arbitrarily changing and increasing or decreasing the number.

[0007] Therefore, an object of the present invention is suitable for limiting the range for restricting outgoing / incoming of a portable radio terminal to a relatively narrow range, and freely changing the range and increasing / decreasing the number. It is an object of the present invention to provide a transmission / reception control system for portable wireless terminals.

And a wireless adapter that can be installed at any location. The communication control device includes a wireless adapter interface that enables communication with the wireless adapter. There is provided a means capable of receiving and recognizing the restriction information regarding the outgoing / incoming call restriction from the control device, and a means capable of transmitting the recognized restriction information to the portable wireless terminal.

A preferred embodiment of the present invention based on such a configuration is as follows. The communication control device can set and change the restriction information on the outgoing / incoming call restriction for each wireless adapter.

The setting and change of the restriction information for each wireless adapter by the communication control device can be performed by a fixed terminal accommodated in the communication control device.

[0011] There are a plurality of forms of regulation information regarding outgoing / incoming call regulation from the communication control apparatus. When the portable wireless terminal receives the regulation information from the wireless adapter, the portable radio terminal is regulated according to the form.

When the portable wireless terminal cannot receive the restriction information from the wireless adapter, the portable wireless terminal automatically returns to the state before the restriction according to the restriction information.

At this time, the antenna 51 shared by the adapter receiving unit 52 and the adapter transmitting unit 53 can switch between transmission and reception by a switch under the control of the adapter control unit 54.

A specific example will be described with reference to FIG. 4 and FIG. 5. When the regulation information a relating to outgoing / incoming from the control unit 15 of the communication control device 1, that is, “outgoing / incoming OFF”, the wireless adapter number information “ When “WA2” is transmitted, the wireless adapter WA2 installed in the conference room A receives this, and the adapter control unit 54 recognizes the restriction information a, that is, “a = transmission / reception OFF”. After recognizing that, the data is sent to the adapter transmission unit 53. Adapter transmission unit 53
Modulates this data as a radio signal
To send over.

Next, with reference to FIGS. 2 and 3, the portable radio terminal 2 receives the radio signal transmitted from the radio adapter 5 and, according to the restriction information regarding the outgoing / incoming call included in the radio signal, the portable terminal 2. An operation example for controlling the wireless terminal will be described.

The portable radio terminal 2 receives the radio signal transmitted from the radio adapter 5 by the antenna 21 and sends it to the radio communication unit 22. The wireless communication unit 22 extracts the restriction information a included in the radio signal when the electric field strength of the radio signal transmitted from the wireless adapter 5 is equal to or higher than the determination recognition level and for a certain period of time or longer. Send to section 26. The mobile terminal control unit 26 recognizes and manages the regulation information a, and according to the content of the regulation information a,
It performs display control on the display unit 23, operation control on the operation unit 24, and ON / OFF control on the power control unit 25. Further, the portable terminal control unit 26 can manage and store a state before controlling the use state of the display unit 23, the operation unit 24, and the power supply control unit 25 according to the regulation information a. This is because the wireless communication unit 22 recognizes the electric field strength level of the wireless signal transmitted from the wireless adapter 5 via the antenna 21,
If the electric field strength is not detected for a certain period of time or more, the restriction information is released and the state before the control based on the restriction information is returned.

As an example, referring to FIGS. 2, 4 and 5, the wireless adapter W installed in the conference room A will be described.
A2 is transmitting regulation information a (transmission / reception OFF) by a wireless signal. At this time, when the person holding the portable wireless terminal 2 enters the conference room A, the portable wireless terminal 2
At 1, a wireless signal is received and sent to the wireless communication unit 22. The wireless communication unit 22 recognizes the electric field strength level of the radio signal, and when the electric field strength level reaches a certain level for a certain time or more, recognizes it as a received signal. a is taken out and sent to the portable terminal control unit 26. The mobile terminal controller 26 controls the regulation information a
When the mobile terminal control unit 26 recognizes the operation state, the operation states of the display unit 23, the operation unit 24, and the power supply control unit 25 controlled by the mobile terminal control unit 26 are stored in the storage unit in the mobile terminal control unit 26. After that, the portable terminal control unit 26 performs display control on the display unit 23 to indicate "outgoing / incoming call rejection range" in accordance with the restriction information a, and the display unit 23 performs display according to the display control.

Further, since the restriction information a includes a control command for turning off the incoming call, the portable terminal control unit 26 makes the incoming call OFF.
Before performing the control, the communication controller 22 and the antenna 21 transmit a message “call rejection” to the wireless terminal interface 13 of the communication controller 1. The wireless terminal interface 13 sends the fact that the portable wireless terminal 2 is in the “call rejection” area to the control unit 15 in the communication device control unit 1, and the control unit 15 determines that the incoming call information for the portable wireless terminal 2 is different from other terminals. If the call is received from the portable wireless terminal, information indicating that the area is the “call rejection” area is transmitted to the terminal on the transmitting side.

With the above configuration and means, when a call is transmitted from the portable radio terminal 2, the portable terminal control unit 26 recognizes the restriction information a, and therefore, responds to the call operation information from the operation unit 24. The transmission operation information is transmitted to the portable terminal control unit 26. When the portable terminal control unit 26 recognizes from the wireless adapter 5 that the electric field strength level of the radio signal is constant and continues for a predetermined time or more, the transmission operation information is transmitted. Is not performed, and the display unit 23 performs display control to display "outside the transmission area".
By displaying "outside the transmission area", the transmission of the portable wireless terminal 2 in the conference room A is stopped.

In the case of an incoming call, the portable terminal control section 26 in the portable wireless terminal 2 determines that the electric field strength level of the radio signal from the radio adapter 5 has been constant for a certain level and has continued for a certain period of time. Is recognized. Since the restriction information a includes the incoming call OFF control command, the portable terminal control unit 26 sends the communication control unit 22 to the wireless terminal interface 13 of the communication control device 1 in FIG. A message of “call rejection” is transmitted via the antenna 21. The wireless terminal interface 13 sends the fact that the portable wireless terminal 2 is in the “call rejection” area to the control unit 15 in the communication device control unit 1, and the control unit 15 determines that the incoming call information for the portable wireless terminal 2 is different from other terminals. If the call is received from the portable wireless terminal, a message “out of the receiving area” is returned to the terminal on the transmitting side. Thereafter, the mobile terminal control unit 26 stops the incoming call to the mobile wireless terminal 2 by stopping the reception function in the wireless communication unit 22.

Next, with reference to FIG. 1, FIG. 4 and FIG. 5, the communication control device 1 stores and manages a plurality of regulation information on outgoing / incoming calls so that a plurality of installed wireless adapters 5 are provided.
The following describes an operation example in which the restriction information is transmitted by distinguishing the application according to the application, and the portable wireless terminal 2 is controlled in a different form for each room.

The storage unit in the control unit 15 of the communication control device 1 stores a transmission / reception restriction information table as shown in FIG. 5, and controls the portable radio terminal for a plurality of restriction information a to e. Are determined in advance, and the wireless adapters WA1 to WA7 installed in the respective rooms are stored in comparison with the respective regulation information tables for each application. Thereby, the restriction information (a to e) based on the restriction information table and the wireless adapter number information (WA1 to WA7) corresponding to the restriction information

The wireless adapter interface 14 sends the wireless adapters WA1 to WA corresponding to the wireless adapter number information.
7, the set regulation information (ae) is transmitted as a wireless signal. Each of the wireless adapters WA1 to WA7 receives a wireless signal through the antenna 51, extracts restriction information by an RF circuit in the adapter receiving unit 52, and sends the information to the adapter control unit 54. The adapter control unit 54 recognizes and manages the received regulation information and sends it to the adapter transmission unit 53. The adapter transmitting unit 53 modulates the regulation information and transmits the modulated information as a wireless signal via the antenna 51, so that the wireless adapters WA1 to WA7 installed in each room can control the portable wireless terminal according to the application.

Referring to FIG. 5 as an example, the portable wireless terminal control of the restriction information b in the transmission / reception restriction information table is "OFF ONLY ON RECEPTION", and the wireless adapter WA7 performs the control. Regulation information b and adapter number information WA7
Is sent from the control unit 15 in the communication control device 1 to the wireless adapter interface 14. When recognizing the wireless adapter number information WA7, the wireless adapter interface 14 modulates the regulation information b and sends the modulated wireless signal as a wireless signal to the wireless adapter WA7 installed in the control room. The wireless adapter WA7 receives the wireless signal with the antenna 51,
The adapter receiving unit 52 transmits the restriction information b from the radio signal to the adapter control unit 54.
The adapter control unit 54 recognizes and manages the restriction information b as “only incoming call is OFF”, so that the adapter transmitting unit 53

The reason for any of the fixed telephones TEL1 to TEL21 is to prevent the system from being easily changed from any terminal, and a fixed telephone capable of changing the system is set in advance.

The procedure operation by any one of the fixed telephones TEL1 to TEL21 is transmitted to the fixed terminal interface 12 of the communication control device 1 as system input data. The fixed terminal interface 12 adds terminal number information to the system input data and sends it to the control unit 15. The control unit 15 determines whether or not the system is a fixed terminal whose system can be changed based on the system input data and the terminal number information. If there is no problem, the currently set outgoing / incoming call restriction information table is used as the restriction information data to set the fixed terminal interface 12. To the fixed terminal that matches the terminal number information via. Specific one of fixed telephones TEL1 to TEL21
When the change information is changed according to a predetermined procedure, the fixed terminal interface 1 is used as change input data.
Send to 2. The fixed terminal interface 12 sends the change input data to the control unit 15. The control unit 15 rewrites the outgoing / incoming call restriction information table in the storage unit according to the change input data. After that, the control unit 15 transmits the rewritten wireless adapter number information and the restriction information to the wireless adapter 5 via the wireless adapter interface 14 so that the restriction information can be changed.

Referring to FIGS. 1 and 4 to 6 as an example, the fixed terminal capable of changing the system is a fixed telephone TEL1 installed in the general affairs department, and the restriction of the wireless adapter WA4 set in the evaluation room. When the information is changed from "a = OFF for both incoming and outgoing calls" to "b = OFF only for incoming calls", a predetermined procedure operation is performed from the fixed telephone TEL1 installed in the general affairs department. It is transmitted to the fixed terminal interface 12. The fixed terminal interface 12 adds the terminal number information “1” to the system input data and sends it to the control unit 15. Control unit 1
5 recognizes the system input data and returns the outgoing / incoming call restriction information table as the restriction information data to the fixed telephone TEL1 of the terminal number information "1" via the fixed terminal interface 12.

Next, when a change is made by a series of predetermined operations in order to change from the fixed information TEL1 to the restriction information “a” of the wireless adapter WA4 to “b”, the fixed terminal interface 12 is input as change input data. Sent. The fixed terminal interface 12 sends the change input data to the control unit 15. The control unit 15 rewrites the transmission / reception restriction information table in the storage unit from “a” to “b” according to the change input data. After that, the control unit 15
Transmits the rewritten wireless adapter number information WA4 and the restriction information “b” to the wireless adapter WA4 via the wireless adapter interface 14, and the wireless adapter WA4 installed in the evaluation room transmits the wireless communication The information is changed from “a” to “b”.

Next, the portable radio terminal 2 recognizes the electric field strength level of the radio signal from the radio adapter 5, and when the level falls below the predetermined level for a predetermined bell time or more, the radio adapter 5
An example of the operation of releasing the control restricted according to the restriction information included in the wireless signal from the wireless adapter 5 and returning to the use state before being controlled by the restriction information from the wireless adapter 5 will be described.

As an example, with reference to FIGS. 2, 4 and 5, the portable radio terminal PHS17 enters the conference room B, and the restriction information a (transmission / transmission) transmitted by the radio signal of the radio adapter WA2. It is assumed that the user leaves the conference room B from a state where the incoming call is controlled to OFF. The wireless communication unit 22 of the portable wireless terminal PHS17 transmits the wireless signal transmitted by the wireless adapter WA2 to the antenna 21.
The transmission electric field strength level is recognized through the, but when it is recognized that the transmission electric field strength level has decreased to the electric field strength below a certain level and that the state has continued for a certain period of time, the restriction information a is released. The control signal is transmitted to the portable terminal control unit 2
Send to 6. The mobile terminal control unit 26 sends a control signal to the display unit 23, the operation unit 24, and the power supply control unit 25 to release the restriction according to the restriction information a. With this control signal, the display unit 23, the operation unit 24, and the power supply control unit 25 are released from the regulation in accordance with the regulation information a, and the portable wireless terminal PHS17 automatically returns. Then, the communication control device 1 receives and recognizes the restriction information a, and gives “rejection of incoming call” before restricting the terminal.
Is transmitted to the wireless terminal interface 13 of the communication control device 1 to the wireless terminal interface 13 of the communication control device 1 to cancel the incoming call prohibition.

With the above configuration and means, when the portable wireless terminal 2 falls outside the electric field strength level of the wireless adapter 5, the portable wireless terminal 2 controlled by the regulation information of the wireless adapter 5 returns to the state before the regulation. Automatic return.

Next, an example of an operation in which an incoming call of the portable radio terminal 2 is transferred to a specific fixed terminal will be described with reference to FIGS.
