Abstract

PROBLEM TO BE SOLVED: To securely stop the transmission of electromagnetic wave in a place where the use of radio is restricted. SOLUTION: Receptive pieces of communication equipment have plural radio parts 11 and 12 which can communicate with the base station of plural radio communication networks. The respective radio parts 11 and 12 receive position registration information from the base station of respective radio communication networks. The control part 16 of communication terminal equipment 1 inhibits the transmission of electromagnetic waves from the radio parts 11 and 12 when base station ID in position registration information which one of the radio parts receives is matched with base station ID which is previously stored in a memory 15 and is inhibited to transmit the electromagnetic wave. When one radio part receives position registration information containing other base station ID except for the base station ID inhibited to transmit the electromagnetic wave, the transmission of the electromagnetic wave from the radio parts 11 and 12 is permitted. The radio parts 11 and 12 transmit signals for the position registration functions of the respective radio communication networks and for incoming/originating control functions as the electromagnetic waves while the transmission of the electromagnetic wave is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal for forming a wireless communication network in combination with a base station.

[0002]

2. Description of the Related Art In recent years, wireless communication networks such as a so-called portable telephone system and a PHS (Personal Handyphone System) have rapidly become widespread. The wireless communication network includes at least one movable mobile station, that is, a communication terminal device, a plurality of fixed stations having mutually different communication areas, that is, base stations, and a mobile communication switch interposed between the base stations. Including stations. All base stations and exchanges are interconnected to form a communication network, which may further be connected to existing public communication networks, such as the public switched telephone network and the integrated services digital network. is there.

In the wireless communication network, in a situation where communication is performed between one arbitrary communication terminal device and another communication terminal device or a terminal device in the public communication network, the arbitrary communication terminal device In the case of a so-called called device, the arbitrary communication terminal device performs the following wireless communication with the nearest base station of the device. After the line connection between the other communication terminal device or the terminal device in the public communication network and the nearest base station, the base station uses a predetermined common control channel, and connects to the arbitrary communication terminal device. On the other hand, a predetermined call signal is transmitted as an electromagnetic wave. The arbitrary communication terminal device always receives an electromagnetic wave in the common control channel, and after receiving a call signal to the device itself, transmits a response signal to the call signal as an electromagnetic wave.
In the above case, for example, if the arbitrary communication terminal device has a so-called answering machine function, regardless of whether the operator of the device performs an operation for a predetermined incoming call,
The response signal is transmitted automatically. After receiving the response signal, the nearest base station uses one of the unused communication channels among all communication channels, and exchanges a signal for communication with the arbitrary communication terminal device as an electromagnetic wave. Send and receive.

In the wireless communication network, the positions of all the communication terminals in the network are determined, for example, in units of a predetermined location registration area in order to efficiently call the communication terminal on the called side from the base station. , Registered in the communication network. Therefore, when the communication terminal device moves from any one of the plurality of location registration areas to any other one, the communication terminal device uses a predetermined common control channel for location registration. Thus, an electromagnetic wave indicating a position registration request is automatically transmitted to the nearest base station.

Recently, a problem has been pointed out that electromagnetic waves used in the wireless communication network cause malfunctions of precision electronic equipment. Examples of the precision electronic device include a medical device. For this reason, there is a demand for self-control of use of the communication terminal device in a place where the precision electronic device exists, for example, in a hospital. For this purpose, Japanese Patent Application Laid-Open Nos. 9-311989, 10-42371, and 10-150406 disclose a method for requesting the operator to refrain from using the communication terminal device in the place. An apparatus is disclosed.

A portable telephone alarm device disclosed in Japanese Patent Application Laid-Open No. 9-311989, a device for restricting use of a portable telephone disclosed in Japanese Patent Application Laid-Open No. 10-42371, and
Each of the mobile phone detection devices disclosed in Japanese Patent Publication No. 406 is installed in a place where use of the communication terminal device is restricted.
The above three devices are communication terminal devices in the place,
In other words, it is possible to receive predetermined electromagnetic waves that are transmitted from a mobile phone or a wireless device and that can cause an electronic device in the place to malfunction. Each of the above-described three devices generates a warning, for example, a message or a warning sound, when the electromagnetic wave is received, in order to cause the operator of the communication terminal device to stop using the device.

[0007] When each of the above three devices is used, it is left to the operator of the device to actually restrict the use of the communication terminal device. Therefore, when the operator does not follow the warning, for example, when the operator inadvertently performs an operation for responding to the call signal in a situation where a call signal arrives at the communication terminal device, Electromagnetic waves are transmitted. Thus, when the above three devices are used, it is difficult to reliably restrict the use of the communication terminal device. Further, as described above, the communication terminal device itself automatically transmits an electromagnetic wave to the base station for automatic reception in the location registration and answering machine functions. Therefore, when the power of the communication terminal device is not turned off, the electromagnetic wave is automatically transmitted from the communication terminal device even though the operator of the device does not intentionally use the communication terminal device for communication. It may be sent.

In view of the above problems, the applicant of the present application disclosed a control method of a portable wireless device in Japanese Patent Application Laid-Open No. Hei 10-135891 for controlling transmission of an electromagnetic wave from a portable wireless device, that is, the communication terminal device. Has been proposed. The wireless communication network using the control method further includes a wireless device that transmits a signal indicating a power-off command of the portable wireless device. The wireless device is installed at an entrance of a place where use of the portable wireless device is to be restricted, and constantly transmits the signal as an electromagnetic wave to the entrance and a space near the entrance. Upon receiving the signal, the portable wireless device automatically turns off the power of the portable wireless device.

Similarly, for automatic control of the transmission of the electromagnetic wave, Japanese Patent Application Laid-Open Nos. 9-331576 and
Japanese Patent Application Laid-Open Nos. 154111, 10-200449 and 10-200958 disclose configurations in which a wireless communication network itself automatically controls the operation of the communication terminal device. A wireless communication network including each of the devices disclosed in the above-mentioned four publications is installed in a place where the use is to be restrained, and the predetermined signal is one of light, radio waves, and sound waves. It further includes a transmitting device that constantly transmits to the space in the place. The mobile phone, the information processing device with a wireless communication function, the mobile communication terminal, and the wireless communication device disclosed in the above four publications, respectively,
The apparatus further includes a configuration for receiving a signal from the transmitting device, and when the signal is received, transmission of an electromagnetic wave is automatically prohibited.

[0010] Further, for automatic control of the transmission of the electromagnetic wave, Japanese Patent Laid-Open Publication No. Hei 10-215483 discloses a portable telephone system for controlling the operation of the communication terminal device. The mobile phone system further includes a prohibited area base station having a prohibited area in which the use is to be banned, and capable of accepting location registration from a mobile phone in the area. After receiving the location registration from the mobile phone in the prohibited area, the prohibited area base station gives the mobile phone notification information for controlling transmission of electromagnetic waves.
After receiving the notification information, the mobile phone turns off the transmission unit in the mobile phone. The prohibited area base station is not connected to a line with another general base station in the mobile phone system. For this purpose, the other base station is
No call is made to the mobile phone in the prohibited area, and as a result, the transmission function of the mobile phone in the prohibited area is always kept stopped.

For automatic control of the transmission of the electromagnetic waves, Japanese Patent Laid-Open Publication No. Hei 10-42362 discloses a portable telephone device comprising a base station and a wireless terminal. In the portable telephone device, the base station, when registering the position of the wireless handset, if the wireless handset is in an area where the use is to be prohibited, the base station itself is notified to the wireless handset. The transmission prohibition mode information is transmitted together with the ID code. When receiving the transmission prohibition mode information, the wireless slave does not transmit an electromagnetic wave in the area of the base station.

[0012]

In order to explain the basic configuration of the plurality of wireless communication networks using the communication terminal device 1 as a mobile station, the basic configuration of any one wireless communication network (hereinafter referred to as “specific wireless communication network”) will be described below. Will be described. Each of the plurality of wireless communication networks includes the same basic configuration as that of the specific wireless communication network, and the detailed configuration is defined based on a standard and communication protocol specific to each wireless communication network.

The specific wireless communication network uses a so-called cell system. That is, each base station belonging to the specific wireless communication network is a fixed station installed in a predetermined service area which is a basic area where the specific wireless communication network can be used. A standby area which is an area, that is, a so-called cell is set. In the specific wireless communication network, the specific wireless communication network is located within the service area of the specific wireless communication network such that an arbitrary point in the service area is included in a standby area of at least one base station belonging to the specific wireless communication network. A standby area for each base station of the communication network is arranged. In the present embodiment, since each of the plurality of wireless communication networks has a certain area as a service area, basically, any point in the area is assigned to each of the plurality of wireless communication networks. It is included in each of the waiting areas of a plurality of base stations to which it belongs. For the location registration function, the service area of the specific wireless communication network is divided into a plurality of location registration areas. At least a part of the plurality of location registration areas may overlap each other. Any one location registration area includes a standby area for one or more base stations.

Each base station of each of the plurality of wireless communication networks has at least one common control channel and a plurality of communication channels for transmitting and receiving signals to and from a mobile station. The common control channel of any one base station of the specific wireless communication network is shared by all mobile stations in the standby area of the base station, and is used for controlling communication between each of the mobile stations and the base station. It is used to transmit and receive control signals. Any one communication channel of the any one base station may include:
When any one mobile station in the standby area of the base station performs communication with a communication partner terminal, a data signal assigned to the arbitrary mobile station and indicating the content of the communication is transmitted. Used to send and receive. The data signal indicates, for example, sound or data that can be handled by a computer. The terminal of the communication partner is another mobile station in the specific wireless communication network, a mobile station belonging to another wireless communication network, or a communication terminal of a wired communication network. The wired communication network is, for example, a public switched telephone network (PSTN) and an integrated services digital network (ISDN).

The communication network of the specific wireless communication network includes, in addition to all the base stations belonging to the specific wireless communication network, one or a plurality of exchanges for mobile communication in the specific wireless communication network, and the specific wireless communication network. One or more position control stations for storing the positions of all the mobile stations to which the mobile stations belong are further included. In a communication network of a specific wireless communication network, a base station, an exchange, and a position control station can transmit and receive signals to and from each other using wired or wireless communication. The communication network of the specific wireless communication network is connected to a communication network of another wireless communication network and a communication network of a wired communication network via a wired transmission path or a wireless transmission path. Note that the specific wireless communication network may constitute a communication network by using an exchange of a wired or wireless communication network other than the network, instead of having the mobile communication exchange.
The specific wireless communication network uses a so-called location registration function for a so-called tracking connection function and a paging function at the time of an incoming call to a mobile station belonging to the communication network, so that the current positions of all the mobile stations belonging to the communication network are determined. , Is registered with the position control station.

The tracking connection function is as follows.
When the terminal of the communication partner intends to start communication with any one of the mobile stations belonging to a specific wireless communication network as a terminal of the calling side, the terminal of the calling side transmits the communication terminal of the communication network. To one of the nearest exchanges in the communication network,
Requests a line connection with any one of the mobile stations, which is a called terminal. The nearest exchange of the calling terminal is:
The current position of the called mobile station is obtained from the position control station, and based on the current position, the caller terminal transmits the current position to the nearest switching station of the called mobile station via the switching center. Connect the line. An exchange closest to the mobile station notifies the at least one base station connected to the exchange of the incoming of the line. The above is the tracking connection function. The paging function is as follows. In the tracking connection function, an exchange nearest to the mobile station notifies the base station of a plurality of standby areas forming any one location registration area including the acquired current position of the arrival of the line at the same time. I do. As a result, all the base stations in the location registration area use the common control channel, respectively, and call the mobile station on the called side, which should be in the standby area of each base station, to call the mobile station. Each signal is transmitted in parallel. The above is the general calling function.

A mobile station of a specific wireless communication network always receives a signal broadcast using a common control channel receivable at the current position of the mobile station. When the called mobile station receives a paging signal for the mobile station, the called mobile station responds to the paging signal, among all the base stations in the location registration area, the electromagnetic wave having the best reception state at the current position. Is selected, and a response signal to the paging signal is transmitted to the base station. As a result, the line having the calling terminal as one end passes through the nearest exchange of the terminal, the nearest exchange of the called mobile station, and one of the base stations selected by the mobile station in this order. Connected to the mobile station. This enables communication between the communication partner terminal and the called mobile station. The transmission of the response signal may be executed after the operator operates the input unit 13 in response to the ringer ringing in response to the call signal, and the mobile station automatically executes the operation regardless of the operation of the operator. Is also good. The so-called automatic incoming call of the mobile station is performed, for example, when the mobile station has an answering machine function.

Each base station of the specific wireless communication network uses the common control channel for the location registration function,
The predetermined position registration information is reported, for example, periodically. The location registration information broadcast from any one base station includes a base station identification signal for identifying the base station from which the information is reported. Further, for example, all base stations in a certain location registration area may broadcast the same location registration information. The mobile station of the specific wireless communication network always receives the location registration information broadcast using the common control channel, and includes at least the latest one of the received location registration information, that is, the current location of the mobile station. The location registration information from the base station in the standby area is stored in the memory 15.

In the present embodiment, the communication terminal device 1 is a so-called portable telephone (Personal Digital Cellar: hereinafter referred to as “PD”).
C) may be referred to as a mobile station of the network and a so-called P
It is assumed that the mobile station also serves as a mobile station of an HS (Personal Handyphone System). In the present embodiment, the configuration of the PDC network and the communication network in the PHS,
It is assumed that the communication sequence between the mobile station and the base station in the network and the PHS is equal to that of the PDC network and the PHS in the prior art. In the following description, "PH" is included in each base station belonging to the PHS and PDC networks, a standby area of each base station, and location registration information from each base station.
"S" and "PDC". Based on these facts, in the present embodiment, there are two wireless units 11 and 12, and the PHS wireless unit 11 which is one of the two wireless units performs wireless communication with the PHS base station. And the PDS radio section 12, which is the other of the two radio sections, includes a configuration for performing radio communication with the PDS base station.

FIG. 2 is a flowchart for explaining a transmission control process of the plurality of radio units 11 and 12 in the control unit 16 of the communication terminal device 1 according to the present embodiment. FIG. 2
In some cases, electromagnetic waves are described as "radio waves". In the description of FIG. 2, it is assumed that one location registration area includes a standby area of one base station. At least the control unit 16
Proceeds from step A1 to step A2 in a state in which the operation is possible, for example, in a state where power for operation is supplied, and when at least one of the plurality of radio units 11 and 12 is in an operable state, for example, When the power supply for the operation is started, the process proceeds to step A3.

In step A3, PHS radio section 11 transmits PHS position registration information from the nearest PHS base station, for example, a PHS base station having a PHS standby area including the current position of communication terminal apparatus 1. To receive. The received PHS location registration information is stored in the memory 15. After the reception, the control unit 16 determines in step A4 the PH based on the received latest PHS location registration information.
It is determined whether a location registration operation for the S base station is necessary. If it is determined that the location registration operation for the PHS base station is not required, the process proceeds from step A4 to step A9, and if it is determined that the location registration operation is necessary, the process proceeds from step A4 to step A5.

The location registration operation is determined, for example, in the following procedure. The control unit 16 sets the two PHS location registration information received by the latest two processes in the repeatedly executed reception process of step A3, that is, the previous PHS location registration information stored in the memory 15 once. The PHS location registration information received in step A3 is compared with the PHS location registration information received in the latest step A3. The control unit 16 determines that the location registration operation for the PHS base station is not required when the two PHS location registration information match, and determines that the location registration operation is required when the two PHS location registration information are different. Judge that there is. This is because, in the former case, the communication terminal device 1 moves only within the PHS location registration area that existed at the time of execution of the older one of the reception processes during the two reception processes, and moves outside the area. In the latter case, it has moved from the PHS location registration area that existed at the time of execution to another PHS location registration area in the latter case. The above is the detailed determination procedure of step A4.

In step A5, the control unit 16 determines the base station ID in the received latest PHS location registration information, that is, the base station I of the nearest PHS base station of the communication terminal device 1.
It is determined whether or not D matches one of all predetermined radio transmission prohibited base station IDs related to the PHS in the memory 15. If they match, the control unit 16 determines that the communication terminal device 1 is in a place where the use of wireless communication is restricted, and in this case, the process proceeds from step A5 to step A6. If they do not match, the control unit 16 determines that the communication terminal device 1 is in a place where wireless use is not restricted,
From step 5, go to step A8.

The control unit 16 prohibits all transmission of electromagnetic waves from all the radio units 11 and 12 in the communication terminal device 1 in step A6. As a result, all the radio units 11 and 12 stop not only the transmission of the data signal indicating the communication content but also the transmission of the position registration request for the position registration operation and the transmission of the response signal of the call signal. As a result, all radio units 11,
Numeral 12 stops the location registration operation and the operation of transmitting and receiving signals for communication with all communication partner terminals, and only receives signals from the base station. Further, the control unit 16 causes the display unit 14 to display a message indicating that the transmission of the electromagnetic wave is prohibited in step A6.

After the display, the controller 16 proceeds to step A7.
It is assumed that the communication terminal apparatus 1 moves from the PHS standby area including the place where the use of the radio is restricted to another PHS standby area other than the PHS standby area including the location among all the PHS standby areas. ,wait. The processing in step A7 is specifically equivalent to the processing in steps A3 and A4. The result control unit 16 determines whether the base station ID in the latest location registration information matches the base station ID in the location registration information one time older than the information, that is, the base station ID in the latest location registration information. While the ID matches the base station ID of the electromagnetic wave transmission prohibition matched in step A5, the process of receiving the PHS location registration information in the PHS radio unit 11 and the process of comparing the information in the control unit 16 are repeated. If the two base station IDs do not match, it is considered that the communication terminal device 7 has moved to the other PHS standby area, and the processing in step A7 ends. After the end,
The process returns from step A7 to step A3.

At step A5, if the base station ID in the latest location registration information does not match any of the base station IDs for which the transmission of electromagnetic waves is prohibited, the control unit 8 determines at step A8 that all the radio units 11 and 12 have Transmission of electromagnetic waves. As a result, the PHS radio unit 11 transmits a location registration request to the nearest PHS base station using a common control channel. After the nearest PHS base station receives the location registration request, the communication network of the PHS, based on the location registration request, determines the location registered in a location control station in the communication network, ie, a so-called PHS service control station. The location information indicating the current location of the communication terminal device 1 that has transmitted the registration request is updated. As a result, all the wireless units 11 and 12 can receive a line from the nearest base station belonging to the wireless communication network corresponding to the wireless unit and transmit a line to the base station. At least after transmitting the position registration request, the process proceeds from step A8 to step A9.

The processing in steps A9 to A14 is different from the processing in steps A3 to A8 in that elements related to PHS, for example, PHS base station, PHS location registration information, PHS
Base station ID and PH that prohibit transmission of electromagnetic waves related to HS
The difference is that the S standby area is replaced by an element related to the PDC network, for example, a PDC base station, PDC location registration information, a base station ID for prohibiting electromagnetic wave transmission related to the PDC network, and a PDC standby area, and the others are equal. Therefore, detailed description of each step may be omitted.

In step A 9, PDC radio section 12 determines the nearest PDC base station having a PDC standby area including the current position of communication terminal apparatus 1 among all PDC base stations.
Receive PDC location registration information from the DC base station. The received PDC location registration information is stored in the memory 15. After receiving, in step A10, the control unit 16 determines whether or not a location registration operation for the PDC base station is required based on the received latest PDC location registration information. The detailed procedure of the determination and the reason thereof are, for example, the same as those in which the PHS location registration information in the determination procedure and the reason thereof in step A4 is replaced with the PDC location registration information.
If the location registration operation for the PDC base station is not required, the process proceeds from step A10 to step A11, and if necessary, the process returns from step A10 to step A3.

In step A11, the control unit 16 stores the base station ID in the received latest PHS location registration information, that is, the base station ID of the nearest PHS base station of the communication terminal device 1, in the PDC It is determined whether or not the ID matches one of all predetermined base station IDs for which radio wave transmission is prohibited. If they match, the control unit 16 determines that the communication terminal device 1 is in a place where wireless use is restricted, and in this case, the process proceeds from step A11 to step A12. If they do not match, the control unit 16 determines that the communication terminal device 1 is in a place where wireless use is not restricted, and proceeds from step A11 to step A14.

In step A12, the control unit 16 controls all the radio units 1 in the communication terminal device 1 in the same manner as in step A6.
All transmissions of electromagnetic waves from 1 and 12 are prohibited. As a result, all the radio units 11 and 12 stop the location registration operation and the transmission / reception operation of signals for communication with all communication partner terminals, and only receive signals from the base station. Further, in step A12, the control unit 16 causes the display unit 14 to display a message indicating that the transmission of electromagnetic waves has been prohibited, as in step A6.

After the display, the control section 16 proceeds to step A13.
Then, the communication terminal apparatus 1 moves from the PDC standby area including the location where the use of radio is restricted to another PDC standby area other than the PDC standby area including the location among all PDC standby areas. Wait.
Specifically, the processing in step A13 is performed in step A9,
The same processing as A10 is performed in step A7 in step A7.
It is realized by repeating the processing of 3, A4. When the communication terminal device 7 has moved to the another PDC waiting area, the process of step A13 ends, and the process returns to step A3.

If the base station ID in the latest location registration information does not match the base station ID of the electromagnetic wave transmission prohibition for all the PDC networks in step A11, the control unit 8 proceeds to step A11.
In step 14, similarly to step A8, all the radio units 11, 1
2 permits the transmission of electromagnetic waves. As a result, the PDC radio unit 12 transmits a location registration request to the nearest PDC base station using a common control channel. After the nearest PDC base station receives the location registration request, the PDC communication network establishes the current location of the location control station in the communication network, that is, the communication terminal apparatus 1 that has transmitted the location registration request in the so-called home memory station. The location information indicating the location is updated based on the location registration request. As a result, all the wireless units 11 and 12 can receive a line from the nearest base station belonging to the wireless communication network corresponding to the wireless unit and transmit a line to the base station.
At least after transmitting the position registration request, the process proceeds from step A14 to step A3.

In the transmission control process of the flowchart of FIG. 2, the processes of steps A3 to A14 are performed by all the radio units 11, 1
It is repeated one or more times over time, for example periodically, until 2 is in a state of pausing operation. When all the radio units 11 and 12 are in a state of suspending operation, the transmission control processing is terminated halfway. The above is the description of the transmission control processing.

When the above-described transmission control processing is performed, all the radio units 11 and 12 start the operation of steps A6 and A12 once the transmission of the electromagnetic wave is permitted in one of steps A8 and A14. Until the transmission is prohibited in any of them, each of the radio units 11 and 12 receives a line from the nearest base station belonging to the corresponding wireless communication network and transmits a line to the base station. Will be possible. Therefore, any one of all the radio units 11 and 12 receives the instruction input of the operator from the input unit 13 during the above-mentioned period or the nearest one belonging to the radio communication network corresponding to the radio unit. When a paging signal from the base station is received, wireless communication is performed with the nearest base station for communication with a communication partner terminal in response to the input instruction or the paging signal.

In the transmission control process, while the process of step A7 is performed, the communication terminal device 1
A plurality of standby areas of other communication networks other than the standby area,
For example, a plurality of PDC waiting areas may be sequentially moved. In this case, the PDC radio unit 12 ignores PDC location registration information from the base station in each PDC waiting area. Similarly, while the process of step A13 is performed, the communication terminal apparatus 1 may sequentially move in a plurality of standby areas of a communication network other than the PDC standby area, for example, a plurality of PHS standby areas. In this case PHS
The radio unit 11 ignores PHS location registration information from base stations in each of the PHS waiting areas. This is because the communication terminal device 1 exists in the PHS and PDC waiting areas including the place where the use of the radio is restricted while the processes of steps A7 and A13 are performed, respectively. Until you leave, regardless of whether you enter or leave a standby area in another wireless communication network,
This is because it is necessary to prohibit transmission of all electromagnetic waves from the communication terminal device 1.

As described above, the communication terminal apparatus 1 transmits the electromagnetic wave in one of the steps A6 and A12 under the condition that at least one of the radio units 11 and 12 is operable. From the time when is prohibited to the time when the transmission is permitted in one of the steps A8 and A14, the transmission of the electromagnetic waves from all the radio units 11 and 12 is all prohibited. As a result, in the above situation and when the communication terminal apparatus 1 is in a standby area of any wireless communication network including a place where use of wireless communication is restricted, transmission of an electromagnetic wave based on a position registration operation, for example, a position registration request Transmission is automatically stopped. As a result, when the communication terminal device 1 has an automatic incoming call function, transmission of electromagnetic waves based on the function, for example, transmission of a response signal to a call signal is automatically stopped.

Thus, in the case described above, the control unit 16 ensures that not only the transmission of electromagnetic waves that the operator intentionally causes the communication terminal device 1 to execute, but also the transmission of electromagnetic waves that the operator does not consciously participate in. Can be stopped. Therefore, for example, when the operator operates all the radio units 11, 1 of the communication terminal device,
If the user forgets to put the communication terminal 2 into the sleep state, the communication terminal 1
The transmission of all electromagnetic waves from can be reliably stopped. Therefore, in a place where the use of wireless communication is restricted, it is possible to prevent electromagnetic waves from the communication terminal device 1 from affecting a precision electronic device installed in the place, for example, a medical precision electronic device. be able to.

The control unit 16 determines whether or not to prohibit the transmission of electromagnetic waves by all the radio units 11 and 12 based on the base station ID in the location registration information. Therefore, the communication terminal device 1
The communication network of the wireless communication network including the communication network may have the same configuration as the communication network of the related art. As a result, the transmission control of the electromagnetic wave can be easily realized only by using the communication terminal device having the above configuration without modifying the communication network of the wireless communication network. Further, the control unit 16 causes the display unit 14 to display a message indicating that the transmission of the electromagnetic wave is prohibited in steps A6 and A12. As a result, the operator can easily recognize whether or not transmission of electromagnetic waves is currently prohibited, that is, whether or not communication is possible using the communication terminal device, by confirming the display contents of the display unit 14. it can. Therefore, the communication terminal device 1 becomes easy to use.

The control unit 16 further includes a base station ID in the latest location registration information in any one of the plurality of wireless communication networks, and a base station for which the electromagnetic wave transmission is prohibited in any one of the plurality of wireless communication networks. When the station IDs match, transmission of electromagnetic waves from all wireless units 11 and 12 is prohibited. Generally, the area of the PHS standby area is smaller than the area of the PDC standby area. Based on these, the control unit 16 controls the transmission of the electromagnetic wave of the PDC radio unit 12 by:
Since the transmission can be performed in both the PDC standby area unit and the PHS standby area unit, the transmission control can be performed more precisely than in the case of performing only in the PDC standby area unit.

In particular, the detailed operation of the components inside the communication terminal device 1 is not limited thereto, and may be realized by another operation as long as the same processing result is obtained. Further, for example, instead of the radio unit 11 for the PHS and the radio unit 12 for the PDC network,
A wireless unit for another wireless communication network may be provided. Further, the communication terminal device 1 may have three or more wireless units. Furthermore, the communication terminal device 1 controls transmission of electromagnetic waves of all wireless units based on at least the base station ID in the location registration information of the location registration function in the wireless communication network corresponding to at least one of the all wireless units.

Further, the communication terminal device 1 is configured to determine, based on the base station ID in the location registration information of the location registration function in the wireless communication network corresponding to at least one of all the wireless units, the electromagnetic wave of the wireless unit other than the wireless unit Configuration for performing transmission control, for example, PD based on the location registration function of PHS
The configuration for performing transmission control of the C radio unit 11 may be sufficient, or the configuration may be reversed.

Further, the communication terminal device may use a control signal for wireless communication between the base station and the mobile station instead of the base station ID of the base station of each wireless communication network. Further, the wireless communication network causes each base station to output a use restriction signal for controlling the communication terminal device 1 instead of the base station ID, and the communication terminal device 1 outputs, based on the use restriction signal,
The transmission of electromagnetic waves of all wireless units 11 and 12 may be controlled. Furthermore, the communication terminal device 1 has only a single wireless unit, and the electromagnetic wave transmission control of the wireless unit is performed only by using the base station ID in the location registration function corresponding to the wireless unit. Good. The electromagnetic waves used for communication with the base station are not limited to so-called radio waves, but may be light.
