2. Description of the Related Art In recent years, with the rapid spread of mobile phones, traffic accidents caused by mobile phone calls while driving a car have increased sharply. Is being discussed. Under such circumstances, telecommunications carriers and manufacturers have been trying to limit calls due to incoming calls while driving as much as possible while driving.
A system for restricting incoming calls from mobile phones has been developed and put into practical use.

FIG. 4 is an explanatory diagram of an incoming call restriction system to which the present invention is applied. In the figure, 1 is a mobile phone, 2 is a radio base station, 3 is an interoffice communication line, 4 is an exchange, 4
-1 is an exchange, 4-2 is an answering machine, 5 is a service control station, 6 is a public line network, and 7 is a general subscriber telephone.

FIG. 5 is a diagram showing a configuration example of a conventional portable telephone. In the figure, 11 is an antenna, 12 is a radio unit,
13 is a storage unit, 14 is a key input unit, 15 is a display unit, 1
Reference numeral 6 denotes a control unit (CPU: Central Processing Unit).

FIG. 6 is a flowchart showing the operation of the conventional incoming call restriction system. In the figure, 61 to 78 are step numbers. The operation of the conventional incoming call control system will be described with reference to FIGS.

First, before starting driving, the driver presses a mode switching key of the key input unit 14 of the mobile phone 1 in order to switch to the incoming call restriction mode (step 61).
The current mode is checked (step 62), and if the mode before the key is pressed is the normal mode (release mode) (step 63), the CPU 1
6 transmits the incoming call restriction mode switching control signal a to the radio base station 2 to which the control line is connected via the radio section 12 (step 64).

When the signal a is received by the radio base station 2, the information is sent to the exchange 4. The exchange 4 transfers the number of the calling mobile station (= mobile phone 1) and the dial number to the service control station 5 in response to the incoming call to the mobile phone that sent the signal a. The service control station 5 instructs the exchange station 4 not to connect to the mobile phone 1 and to perform control switching of the system so as to connect to the answering machine 4-2. After completing these series of preparations, the base station 2
An incoming call restriction mode switching completion signal b is transmitted to the mobile phone 1 using the control line (step 65). The service control station 5 is a mobile communication control device, and is a system having a service control function for providing advanced network services such as an incoming call charging service and a flexible charging.

In this state, when there is an incoming call from the caller of the general subscriber telephone 7 to the portable telephone 1 (step 66,
67) Then, the exchange 4 sends a message to the caller 7 indicating that the called party is driving, and the communication (= connection processing) is terminated (steps 68 and 69). If the other party has subscribed to the answering machine service, the caller can also record a message before the end of the communication. At this time, only the information b indicating that there is an incoming call is transmitted from the base station 2 to the mobile phone 1 through the control line, and the incoming call operation is not performed.

When returning to the normal mode, the key input unit 1
The user presses the mode switching key No. 4 (step 70). Returning to step 62, step 63 proceeds to step 71 where an incoming call can be answered at step 74. By using this function, if there is an incoming call while driving, the incoming call is not made directly to the mobile phone, so the driver can concentrate on driving and suppress the occurrence of accidents caused by talking on the mobile phone while driving It is effective to do.

[0010]

However, in the above-mentioned conventional portable telephone with the incoming call restriction function, the user has to set and release the restriction function by himself / herself every time the user gets on and off the car, which is inefficient. At the same time, if you accidentally forget the setting / cancellation operation, you will receive a call when driving, and you will be able to answer the phone, or even if you get off the car and you can talk, the restriction function is set There were many problems that the inconvenience of not being able to receive important tasks arises because of being left as it is.

Therefore, in the present invention, since the setting / cancellation of the incoming call restriction function is performed manually every time the passenger gets on / off, the setting or cancellation is likely to be forgotten, and in many cases, it is not possible to switch to the correct setting state according to the situation. In order to solve this conventional problem, by interlocking with the remote control door lock system of the car and unlocking / locking the door when getting on and off,
It is an object of the present invention to provide a mobile phone having an incoming call restriction function in which the setting / cancellation of the incoming call restriction function is automatically performed and the mode can be quickly and reliably switched according to the situation.

[0012]

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, the same reference numerals are given to the same parts as in the prior art. Reference numeral 17 denotes an antenna, 18 denotes a door lock system receiving unit, and 19 denotes a demodulation unit. Conventionally, when setting the incoming call restriction function of the mobile phone, the mode switching key of the key input unit 14 is manually pressed. However, in the present invention, the remote control door lock can be performed without pressing the mode switching key manually. The gist is that a radio wave of the system is received by a door lock system receiving unit 18 via an antenna 17 and demodulated by a demodulating unit 19 to set / cancel an incoming call restriction function of the mobile phone. Hereinafter, the present invention will be described in detail.

Generally, a remote control door lock system is
A transmitter that transmits the identification code for locking and unlocking on a weak radio wave, and receives the radio waves and activates a door lock relay in the driver's seat side door according to the identification code type to lock or unlock (unlock) ) The receiver is installed inside the vehicle driver's seat side door, and the transmitter is used alone as a remote control key or integrally with the key of the vehicle.

Considering the situation in which this system is used, usually, when the driver stops driving and leaves the vehicle, or temporarily leaves the vehicle to complete his business, locks the door locks and drives the vehicle to drive. When getting on the door, unlock (unlock) the door lock. That is,
When an unlocking operation is performed from outside the vehicle by a remote control key, it is determined that driving has started, and when a door lock locking operation has been performed, it can be determined that driving has been stopped and the vehicle has left.

In this system, when locking or unlocking the door lock, if the lock or unlock button of the transmitter is pressed within a short distance (within several meters), a code corresponding to the type of the pressed button is converted to a weak radio wave. It is sent on top of it. From the above determination, the present invention utilizes the weak radio wave of the remote control door lock to perform the automatic switching operation of setting or canceling the incoming call restriction mode while the mobile phone is operating.

The switching operation is specifically described above.
In the remote control door lock system, an identification code (e.g.,
(Consisting of vehicle body number + locking / unlocking code). That is, if the mobile phone has a means for recognizing whether or not the identification code is a code to be processed, it is possible to prevent a mode switching error due to a radio wave transmitted from another remote control key. Therefore, first, in order for the mobile phone to recognize the identification code used for the automatic switching determination of the mode, an operation of storing both the unlocked and unlocked identification codes after demodulation in the rewritable storage means is performed.

FIG. 2 is a flowchart showing the operation of the initial setting according to the present invention. FIG. 2A shows the initial setting for performing the setting operation of the incoming call restriction, and FIG. 2B shows the initial setting for performing the releasing operation. Is shown. 20 to 29 are step numbers.

As a procedure example, first, the state of the mobile phone is
The remote controller door lock identification code receiving mode is set by key operation (step 20). In this state, the locking key of the remote control key is pressed from a short distance, and the locking code is transmitted (step 22). The mobile phone receives the radio wave and demodulates it (step 23), and stores it as a target lock code in the storage means (step 24). Then, the release code is set to the remote control door unlock identification code reception mode by key operation (step 2).
5, 26), and store the same by the same operation (step 29).

With only the simple preparation described above, thereafter, if the same vehicle is used, it is possible to automatically set / cancel the incoming call restriction mode of the portable telephone in conjunction with the remote control door lock system. The operation will be specifically described.

FIG. 3 is a flowchart showing the mode switching operation of the present invention, and 31 to 53 are step numbers.

When the door lock release key of the remote control key is depressed to get on the parked car, the door lock is released and the receiver for the remote control lock system inside the mobile phone transmits the radio wave transmitted from the remote control key. Capture and demodulate (steps 32 and 33). The CPU 16 performs a comparison operation between the demodulated identification code and the identification code stored in the storage means by the above-described storage operation (steps 34 and 35), and if the codes match, sets the reception restriction mode (step 34). 36), a switching signal is transmitted from the radio unit to the base station through the control line (step 37). By this operation, the base station switches to the incoming call restriction mode in the same manner as in the above-described conventional case (steps 38 to 42).

At this time, in order to clearly notify that the mode has been switched, a switching confirmation sound is issued from a speaker, a guidance message stored in advance in the storage means, or the current mode is displayed on the display unit.

Next, a case where the user gets off the vehicle and locks the door will be described. In order to lock the door, the driver goes out of the vehicle and presses the locking key of the remote control key. At this time, the door is locked, and the receiver for the remote control lock system inside the mobile phone captures and demodulates the weak radio wave transmitted from the remote control key (steps 32 and 3).
3). The CPU 16 performs a comparison operation between the demodulated identification code and the identification code stored in the storage means by the above-described storage operation (steps 34 and 44), and if the codes match (step 45), control is performed from the radio unit. A switching signal is transmitted to the base station by the signal (step 46),
The incoming call restriction mode is released. With this operation, the base station switches to the normal mode in the same manner as in the above-described conventional case (steps 47 to 52).

At this time, also in order to clearly notify that the mode has been switched, as in the case of setting the incoming call restriction mode,
A switch confirmation sound from a speaker, a notification of a guidance message stored in advance in a storage unit, or a display of a current mode is performed on a display unit. By this operation, it is possible to automatically return to the normal state.

[0028]

As described above, according to the present invention,
Since the incoming call restriction mode is switched in conjunction with the locking or unlocking operation of the door indicating clear entry / exit from the remote control door lock system of the car, the complexity of setting / releasing the incoming call restriction function by hand can be reduced. At the same time, since a situation in which the operation is forgotten does not occur, it is possible to automatically set a mode according to the situation. Further, since the control is performed using the identification code in the remote control door lock system, there is little danger of malfunction due to other remote control keys, and the mode switching can be reliably performed according to the situation.
