Here, the case where the power is turned on before the mobile terminal is brought into the car will be described. To unlock the car door, the driver can unlock the car door with the keyless entry provided on the ignition key or provided as an option, or near the doorknob. A key may be inserted into a key slot to unlock the door of a car. When used by keyless entry, the receiving part on the automobile side is always energized, and when there is an electromagnetic induction action from the keyless entry, the unlocking of the door of the automobile functions. Step 1-1: As shown in Figure 6, in the case of unlocking the door with a key, insert the key into the key slot near the doorknob and determine if the key has unlocked the door of the car. If the key does not unlock the car door, go to step 16. Step 1: When unlocking a car door with a keyless entry, determine if there was a received signal to unlock the car door with the keyless entry. In the case of the wireless radio wave method, it receives, and in the case of the infrared method, it receives the data signal. Here, if the operation process of unlocking the door by the keyless entry is not performed, the process proceeds to step 16. Step 2: In the keyless entry receiver, the receiver (or receiver) electrically reacts to the control signal from the outside and sends an electrical signal to the microcomputer (reference numeral 3 in FIG. 1) mounted on the automobile. .. Here, a control signal for releasing the door lock is sent to the door lock by the program determination process related to the door lock. Step 3: Receive the control signal from the microcomputer to unlock the mechanical door installed on the door by electromagnetic force. Step 4: Since Step 1-1 or Steps 1 to 3 have been performed, the driver manually opens the door. Step 5: By opening the driver's door, the door open / close detection switch (reference numeral 5 in Fig. 1 and Fig. 3) installed near the support (door hinge 15 in Fig. 3) that supports the door of the car is opened. Judge whether or not. If the door open / close detection switch does not respond, go to step 16. Step 6: When the driver gets into the car and the contact switch detects that the door is closed by the door open / close detection switch in step 5, the door open / close detection signal (electrical signal) is sent to the microcomputer, and the microcomputer sends it. , Recognize the open / closed state of the door. Step 7: The driver inserts the ignition key into the ignition switch section and rotates the ignition key to start the engine. By this rotation, the contact position of the ignition key switch is changed, the code is collated, the power-on signal is input, the battery power is energized, and the battery voltage of the battery power is supplied to the microcomputer. When the power is supplied, the microprocessor starts the engine starting operation, rotates the starter of the automobile engine, and starts the engine. If you do not want to start it, go to step 16. Step 8: The car can be driven by starting the engine of the car and running it in a steady state. Step 9: When the car is driven with the intention of moving the car to the driver's destination, various sensed electric signals from the pulse input unit are input to the microcomputer, the driving information of the car is obtained, and the car is driven. Determine if you are doing it. If not running, go to step 16. Step 10: When the microcomputer determines that the vehicle is running, it refers to the communication regulation signal transmitter (reference numeral 9 in FIGS. 1 and 3) in a specific area of the vehicle (driver, near the driver's seat). ) Is instructed to send a communication regulation signal by electromagnetic waves. Step 11: The communication regulation signal transmission unit transmits a communication regulation signal targeting the mobile terminal to a specific area (near the driver of the car) according to the notification instruction of the microcomputer. Step 12: After transmitting the communication regulation signal, information signals are acquired by various sensors to determine whether or not the vehicle is running. Here, when it is determined that the automobile is traveling, the microprocessor sends a predetermined control signal to the communication regulation signal transmission unit in step 11, and subsequently transmits the communication regulation signal. Step 13: Next, in order to prevent the transmission of the communication restriction signal from being stopped due to a stop such as waiting for a signal, the timer built in the microprocessor is activated and counts a predetermined time. start. The timer operation determines whether or not the car is running. Step 14: After the timer finishes, the microprocessor determines if the car is running. If it is determined by the information signals from various sensors that the vehicle is running even after the timer operation is completed, the process in step 8 is performed. Step 15: When it is determined that the vehicle is not running, the microprocessor sends a control signal instructing the communication regulation signal transmission unit to stop the communication regulation signal transmission operation. Step 16: End a series of communication restriction signal transmission related operations. As described above, in the present embodiment, when the opening / closing of the door is detected, the mobile terminal is brought into the automobile, and then it is determined by various sensors that the automobile is running, the communication regulation signal provided in the automobile is provided.

<< Flowchart of Mobile Terminal >> FIGS. 8 and 9 are flowcharts of a procedure showing a processing procedure in which a mobile terminal brought into an automobile receives a communication regulation signal and is subject to communication regulation. Here, the case where the power is turned on when the mobile terminal is brought into the car or the case where the power is turned on after being brought into the car will be described.

【0021】

The use of mobile terminals is restricted in a specific area (near the driver) where a weak communication restriction signal is received. That is, since the function does not work in the passenger seat and the rear seat of the automobile, it is possible to transmit and receive voice and packet transmission to and from a normal wireless base station. Step 1: Put the mobile device from the unpowered state (power off, power off) to the power on (power on) state. Step 2: When the power is turned on, it communicates with the wireless base station (reference numeral 121 in FIG. 12), confirms the telephone number of the mobile terminal, confirms the position, etc. so that incoming and outgoing calls can be made, and after the processing, , It becomes a waiting state and becomes an intermittent reception state. That is, it searches for the nearest wireless base station with the communication network (network) side, transmits the telephone number and location information of its own unit by weak radio waves, and performs location registration and the like. Intermittent reception then constantly monitors between the mobile terminal and the radio base station under the subscriber exchange station (reference numeral 123 in FIG. 12). Step 3: The microcomputer mounted on the vehicle (reference numeral 3 in FIG. 1) determines that the vehicle is running, and the vehicle is notified to the communication regulation signal transmitter (reference numeral 9 in FIGS. 1 and 3). Sends a communication regulation signal consisting of electromagnetic waves to a specific area (near the driver) of. Whether or not the transmission restriction signal has been detected in the receiving unit of the mobile terminal (reference numeral 36 in FIG. 2, which is different from the transmission / reception system such as voice and packet transmission with the wireless base station) that has received this communication restriction signal. To judge. If the communication restriction signal is not detected, the process proceeds to step 16. Step 4: Since the use of the mobile terminal is limited, the control unit (reference numeral 24 in FIG. 2) of the mobile terminal displays a message indicating communication restriction on the display unit (reference numeral 28 in FIG. 2) in advance. Step 5: The control unit locks the input process from the input key. As an actual operation, the input signal from the key is not received. Step 6: Next, it is determined whether the communication restriction setting preset in the mobile terminal is the answering machine function or the drive mode (D mode). Since the answering machine function requires a paid contract with the telecommunications carrier, it shall be automatically set to the drive mode if it is determined that this contract has not been made. The setting is notified to the subscriber exchange station, which is a higher-level station, via the radio base station, and the message "Because I am driving now ..." is played to the person who made the call. If the answering machine mode is set, go to step 12. Step 7: After the setting process in step 6, execute the communication regulation function. The mobile terminal in the driver's seat restricts incoming and outgoing functions such as voice and packet transmission. However, intermittent communication is performed with the wireless base station to confirm the location. Since the reception by the transmission / reception antenna (reference numeral 21 in FIG. 2) and the reception by the communication restriction signal receiver (reference numeral 36 in FIG. 2) are independent, the communication regulation of the mobile terminal and the radio base station are separated. It goes without saying that compatibility with intermittent communication is possible. Step 8: After the function is started in step 7, the timer (reference numeral 38 in Fig. 2) built in the control unit of the mobile terminal is activated, and the communication regulation signal is intermittently output at the receiver of the mobile terminal while the timer is operating. Determine if it has been received by. If the communication restriction signal is being received, the process returns to step 7 and the communication restriction is continuously executed. Step 9: If the communication restriction signal is not received by the receiving unit after the timer has finished operating, the control unit of the mobile terminal cancels the communication restriction function that has been executed so far. Step 10: The control unit of the stirring band terminal returns to the state before the communication regulation was enforced. Return to the standby state in step 2. Further, in response to the cancellation of the communication restriction action of the mobile terminal, a control signal is transmitted so that the subscriber exchange station of the higher-level station performs a normal function operation via the nearest wireless base station. Step 11: Via the nearest radio base station, the subscriber exchange receives a control signal that performs communication function operations in a normal network, and receives a common line signal network (common communication line, control line; reference numeral 125 in FIG. 12). ) Is sent to the control unit of the service control station (reference numeral 126 in FIG. 12) to send an instruction to cancel the function to the answering machine. Step 12: In step 6, if the answering machine function is selected by the communication regulation setting preset for the mobile terminal, the answering machine function setting is set to the control unit of the service control station via the nearest wireless base station. Send instructions. In response to this, the control unit of the service control station checks the history in the mobile terminal information database and instructs the answering machine to execute it. Step 13: The answering machine performs the prescribed functional operation. For example, a communication line is connected to a caller's call from another network, an appropriate message is inserted, and a message from the caller is recorded. Step 14: In the answering machine, it is determined whether or not the control unit of the service control station has sent a control signal for instructing the answering machine to cancel the function. If there is no control signal, the process goes to step 13. Step 15: The control unit of the service control station sends a control signal for canceling the setting to the answering machine, and stops services such as a series of calls and answering functions.

【0022】

When this setting is complete, go to step 16. Step 16: Finish a series of functions. As described above, in the present embodiment, when the opening / closing of the door is detected, the mobile terminal is brought into the vehicle, and then it is determined that the vehicle is running, the mobile terminal is transmitted from the communication regulation signal transmission unit provided in the vehicle. By transmitting a communication restriction signal to the mobile terminal, the use of the mobile terminal is restricted, and the function is switched according to a preset process. Therefore, the driver can concentrate on driving without worrying about the caller's call and can contribute to the realization of safe driving. In the present embodiment, only incoming / outgoing calls are regulated, and since the network side is accessed intermittently, the normal function will be restored if the communication regulation is lifted. Further, when it is determined that the automobile has stopped running, the normal communication function can be automatically performed.

<< Sequence of Mobile Terminal Communication Regulation >> FIGS. 10 and 11 are diagrams showing a sequence of communication regulation processing in the mobile terminal communication regulation device of the present embodiment. The car is in a stopped state, and at the same time, the mobile terminal is not turned on (power off) (step 1), and the mobile terminal is brought into the car after the power is turned on, or brought into the car and then carried. When the power of the terminal is turned on (step 2), the telephone number and location of the own unit are registered with the nearest wireless base station, and various information data of the mobile terminal is registered in the subscriber exchange station, which is a higher-level station (step 2). In step 3), the mobile terminal then performs intermittent reception between the nearest radio base stations and enters the standby state unless there is a call from another network (step 4). The engine of the car is started by the driver, the car starts running toward the destination (step 5), and the microcomputer provided in the car collects information by various sensings that detect the operating state information of the car, and the car When it is determined that the vehicle is running, the communication restriction signal transmission unit transmits a communication restriction signal (step 6). When an electromagnetic wave is transmitted from the communication regulation signal transmitting unit, the mobile terminal subject to communication regulation by receiving this electromagnetic wave executes a preset communication regulation mode (step 7). The communication restriction mode is a form in which the answering machine function or the drive mode is executed, and at the same time when this setting is executed, an information signal is sent to the subscriber exchange of the upper station via the network. The control signal is sent from the nearest radio base station on the network side, which has received the information signal, to the service control station via the subscriber exchange (step 8). The control unit of the service control station instructs the mobile terminal information database to prepare various information of the mobile terminal registered in advance. This manages mobile terminal information, service zone (that is, mobile terminal location information), answering machine service contract information, message presence / absence information, and the like. If the information is confirmed by the service control station, a control signal for managing the information from the mobile terminal is sent to the subscriber exchange station. next, The mobile terminal is notified as a response signal that confirmation has been obtained via the nearest wireless base station. Upon receiving the response signal, the mobile terminal notifies the message on the display unit and the operation status, indicating that the communication regulation is executed (step 9). When a call is made from another network, the call control signal is sent to the subscriber exchange station and the service control station via the barrier exchange station (reference numeral 124 in FIG. 12). In response to this, the service control station performs the answering machine function or the drive mode execution process based on the settings of the mobile terminal information database (step 10). Therefore, the interconnection function is set between the barrier exchange station, the service control station, and the answering machine to perform security check, channel setting, answer setting, etc. (step 11), message voice transmission, and message recording processing. Etc. (step 12), set the interconnection function to set the line between the other network and the barrier exchange mentioned above, and send out the necessary data (step 13). The caller on the other network side recognizes in the message that the person who wants to connect to the dial line cannot connect to the line, and if necessary, records a voice message and disconnects the communication line. In response to this, the barrier exchange will carry out the procedure for disconnecting the communication line (step 14). When the car arrives at the destination and stops (step 15), the microcomputer provided in the car collects information by various sensors that detect the operating state information of the car, determines that the car has stopped, and communicates. The transmission of the communication regulation signal from the regulation signal transmission unit is stopped (step 16). The transmission of the communication restriction signal consisting of electromagnetic waves is cut off from the communication restriction signal transmission unit, and the mobile terminal that intermittently receives this communication restriction signal and enforces the communication restriction releases the communication restriction and displays it on the display unit. , Notification is given by displaying a message indicating that the regulation has been lifted, displaying an icon, switching the display color of the display unit, etc. (step 17). By lifting the communication regulation, a control signal including the lifting of the communication regulation is transmitted to the mobile communication network. Receive this control signal In the digit mobile communication network, in response to the request of the mobile terminal, the information is confirmed in the mobile terminal database of the service control station, and a predetermined process is performed (step 18). That is, the mobile terminal controls the normal communication line connection and enables the formation of a call line from another network. In the mobile terminal, the number of messages registered in the answering machine service while the communication regulation is being enforced, confirmation of voice messages, etc. are inquired to the service control station or the answering machine device to confirm. Since e-mail (packet transmission) is not a delivery service function, the mobile terminal owner shall confirm the information by making an inquiry to the packet communication system via the packet communication network (not shown). Depending on the settings, it is also possible to access the packet communication system from the service control station in the mobile communication network and deliver the stored e-mails and the like to the mobile terminal having a predetermined service contract (step 19). As described above, in the present embodiment, the communication function of the mobile terminal is restricted by transmitting the communication regulation signal by the processing system, the opening / closing of the door of the automobile is determined, and it is determined that the automobile is running. It is effective in realizing safe driving because the implementation process is performed when it is done. It is expected that the location can be easily confirmed even on the network side because the mobile terminal is not turned off (power off) but limited outgoing and incoming calls are restricted (call form is restricted). It enables emergency call response and location information message notification to the caller. Make adjustments and confirm. Since e-mail (packet transmission) is not a delivery service function, the mobile terminal owner shall confirm the information by making an inquiry to the packet communication system via the packet communication network (not shown).
