In this case, the memory 42 is provided with a table in which each base station is associated with information on its position.

When the search for information is completed, the searched information is transmitted from the information providing server B to the communication terminal A (S14). The transmission is performed via the communication unit 40.
That is, the communication unit 40 functions as a transmission unit that transmits the overwrite information. The transmitted information is, for example, positional information (for example, longitude and latitude) of a certain place. In the case of accident frequently occurring point information, positional information on the searched accident frequently occurring point is transmitted.

Then, in the communication terminal A, the communication unit 1
2 and the like is received (S15). The communication unit 12 and the like function as a receiving unit that receives the overwrite information. The received information is temporarily stored in the reception information storage unit 16b in the data storage unit 16 of the memory 14 via the CPU 28.

In the above series of operations, operations performed by the communication terminal A side, for example, steps S10, S12,
S15 and the like are performed based on the information acquisition program.

The received information stored in the received information storage section 16b is overwritten on the map information stored in the map information storage section 16a (S16). That is, the map overwriting program overwrites a predetermined position in the map information because the received information includes the position information. For example, in the case of accident frequently occurring point information, a sign indicating the information is added. In this case, the overwriting program and the CPU 28 that operates based on the overwriting program function as the overwriting processing unit.

FIG. 7 shows an example of a case where the map information is displayed. That is, FIG.

Note that the display contents shown in FIG. 7 are a part of the map information and are display contents in the navigation system. That is, the communication terminal A functions as an information overwriting device.

In addition, a predetermined notification target is set to be notified, and when the vehicle approaches the notification target while the vehicle is running, the notification is performed by the notification program. For example, when an accident-prone spot is set as a notification target, the distance between the own vehicle position and the accident-prone spot existing on the map information is always calculated, and when the distance is within a predetermined distance, the voice output unit 22 outputs “Nearby”. There are places where accidents occur frequently. " In addition, the distance to be calculated may be a distance on the road, so that a notification such as “There is a point where accidents frequently occur at a point ○ km away” may be performed.

As described above, according to the information providing system S of the present embodiment, the information is automatically acquired by the communication terminal A and is automatically overwritten on the map information, so that it is not necessary to overwrite the map one by one. .

In the above description, the information providing server B searches for information near the position where the communication terminal A is located. However, the present invention is not limited to this. May be specified to search for the specified area.

Further, the information providing server B is connected online with a terminal for controlling a bank account (hereinafter, “bank terminal”),

In this case, the communication terminal A transmits a predetermined ID code (specific information) to the information providing server B. This ID code is a code for specifying the communication terminal A or a user who uses the communication terminal A. As an example, when the mobile terminal K is a mobile phone, the phone number of the mobile phone is cited. Note that, other than the telephone number, another number may be used as the ID code. Then, when the information is retrieved and transmitted to the communication terminal A side, the information providing server B
Calculates the charge to be charged, sends the charge and the ID code to the bank terminal, and the bank terminal debits the charge from the account corresponding to the ID code, and transfers the charge to the account managed by the information providing server B. Will do.

When transmitting the search information in step S14, the area information of the area where the vehicle is located may be transmitted based on the position of the vehicle. That is, in the database 44, regional information including information on famous places, restaurants, etc. in each region is stored for each region, and the above-described step S1 is performed.
Based on the information of the base station transmitted in step 1, the area information about the corresponding area is transmitted. Note that an advertisement fee may be collected by using a restaurant or the like included in the local information as an advertisement. For example, each time information about the advertiser is distributed, a predetermined fee may be deducted from the account of the advertiser in the bank terminal and credited to the account managed by the information providing server B. That is, to the bank terminal, information for instructing a debit, information for specifying a debit account, and information on a debit amount are transmitted, and information for instructing a deposit, and By sending the identifying information, the bank terminal will debit the amount from the account and
Deposit into the deposit account.

Further, another user may provide various kinds of information to the information providing server B so as to obtain a fee. In other words, a person who knows that an accident has occurred can transmit and provide information such as the location, the date, the type of accident (information between cars, car-to-person, etc.) to the information providing server B, In response to the provision of the information, a deposit is made in the bank account of the information provider.

Next, a second embodiment will be described. Second
In the embodiment, the mobile terminal L (see FIG. 8)
Various operations in a vehicle such as an automobile are performed through the. That is, the mobile phone terminal L and the communication terminal A constitute a remote operation system T.

In this case, the communication terminal A has the same configuration as that of FIG. 2, but the program storage section 18 of the memory 14 in the communication terminal A stores the telephone number transmitted from the mobile telephone terminal L. And a vehicle operation program storage section in which a vehicle operation program is stored. The vehicle operation program is a program that outputs a signal to start the engine of the vehicle when it is determined that the telephone number is a predetermined telephone number in the determination of the determination program.

Further, a telephone number for receiving a call is set in the communication terminal A. That is, the communication unit 12 has a mobile phone function, a certain telephone number is set, and when a call is made to the telephone number, the communication unit 12 can receive a call. In addition, information on the telephone number of the mobile phone terminal that permits the operation is stored in the data storage unit 16 of the memory 14. That is, information on the telephone number of the mobile phone terminal L is stored as telephone number information. In this case, the data storage unit 16 functions as the telephone number storage unit and the specific information storage unit.

A portable telephone terminal L for performing the operation of the second embodiment has the same configuration as a normal portable telephone terminal. As shown in FIG. , A microphone 114, a control unit 116, a display unit 118, an input unit 120, and a memory 122.

Here, the radio control unit 110 controls radio communication via an antenna. For example, in the case of a PHS terminal, a transmission / reception amplifier, a modem, a TDMA processing unit,
It includes a codec section, an audio amplification section, and the like.

The control section 116 controls the operation of each section in the mobile phone terminal L. Also,
The display unit 118 is a display device for displaying various information, and is configured by, for example, an LCD. The input unit 120 is a key for performing an input operation. Also,
The memory 122 is a storage device for storing various information.

The operation of the remote control system T having the above configuration will be described with reference to FIG. First, a call is sent to the communication terminal A using the mobile phone terminal L. That is,
A call is sent to the telephone number of the communication terminal A. Then, the communication terminal A receives the call via the base station, the public line network, and the base station. At this time, the information (telephone number information, specific information) of the telephone number of the mobile telephone terminal L, which is the terminal on the calling side, is sent to the communication terminal A side and received by the communication unit 12 (S30). That is, the communication unit 12 functions as the telephone number information receiving unit and the specific information receiving unit. That is,
For the mobile phone terminal L, a setting is made to notify the destination of the telephone number of the mobile phone terminal L.

That is, FIG. 10 shows an example of an incoming call sequence in a mobile phone.
At any timing in the incoming call sequence shown in FIG. 10, information about the telephone number of the mobile phone terminal L is sent from the base station center side to the communication terminal A. As the timing of transmitting the information, a stage before “calling” in the incoming call sequence or the like can be considered.

Then, a call is made from the base station center side, but the communication section 12 does not respond to this. In other words, it is not set to the state during communication. That is,
The telephone number information is received in a preprocessing stage before line connection. Although the communication state is not established, the information of the telephone number of the mobile phone terminal L has been received through the communication unit 12, and thus this information is temporarily stored in the data storage unit 16 of the memory 14. . In addition, since the communication state is not established, the telephone charge can be prevented.

In other words, the above operation is performed when a call is made to a certain mobile phone terminal in the mobile phone and the number is set to be notified even if the mobile phone terminal does not go on-hook. The telephone number of the person is displayed, but this function is used.

Then, the communication terminal A makes a determination on the transmitted telephone number information (S31). That is, the determination program determines whether the transmitted telephone number information is a correct telephone number. That is, in this determination program, the telephone number given to the mobile phone terminal L is set and stored in advance as the number for authentication, and the stored telephone number and the transmitted telephone number are stored. It is determined whether or not matches. This determination is performed by the CPU 28 serving as the determination unit. Therefore, if a call is made from a mobile phone terminal to which a telephone number other than the preset telephone number is assigned, the different telephone number is notified, and it is not determined that the telephone number is correct. If the transmitted telephone number information is a correct telephone number, the process proceeds to step S33, otherwise, the process ends (S32).

In step S33, the CPU 28 serving as the signal output unit outputs a predetermined output signal to the interface 2
6 (S33). If the predetermined output signal is set as a signal to instruct engine start, a signal to instruct engine start is transmitted to the engine starting device (see FIG. 2). Then, the engine starting device starts the engine. In other words, by transmitting the signal, the same operation as when the operation for actually starting the engine is performed is obtained. That is, the signal is output when the operation for actually starting the engine is performed. It will have the same effect as the signal output to the starter.

If the locked door is set to be unlocked, a signal for instructing unlocking is transmitted to a door lock control device (not shown) via the interface 26. Then, the door lock control device unlocks the door. That is, in the case of the present embodiment, the communication terminal A functions as an operation control device for operating the operation target.

Incidentally, starting the engine and releasing the door lock, etc.
When a plurality of types of operations are performed using the mobile phone terminal L, the mobile phone terminal L sends operation type information, that is, information indicating operation details. Also, the memory 14
The program storage unit 18 stores a determination program storage unit that stores a determination program for determining the telephone number transmitted from the mobile phone terminal L, similarly to the above, and further stores a vehicle operation program. A stored vehicle operation program storage unit is provided. The vehicle operation program analyzes the operation type information sent from the mobile phone terminal L when it is determined in the determination program that the telephone number is a predetermined telephone number, and outputs an output corresponding to the operation type information. This is a program that outputs signals.

That is, first, a call is sent to the communication terminal A using the mobile phone terminal L. At this time, in the same manner as described above, the information (telephone number information, specific information) of the telephone number of the mobile phone terminal L, which is the terminal on the calling side, is sent to the communication terminal A side and received by the communication unit 12 (S40) ). That is, the mobile phone terminal L is set to notify the telephone number of the mobile phone terminal L to the destination.

That is, at any timing in the incoming call sequence shown in FIG. 10, information on the telephone number of the portable telephone terminal L is transmitted from the base station center to the communication terminal A.
Sent to. As the timing of transmitting the information, a stage before “calling” in the incoming call sequence or the like can be considered.

Then, during communication, that is, when a line connection state is established, the mobile phone terminal L performs an operation for designating an operation type. In this case, unlike the above case, the state of the line connection, that is, the state of communication shown in FIG. 10 is established.

As the operation for designating the operation type, an operation set in accordance with the operation type, such as starting the engine or unlocking the door, is performed. For example, if the engine start is defined as “* 10”, this “* 10”
To operate. Then, the information of the instructed content is transmitted to the communication terminal A as the operation type information, and the communication terminal A receives the operation type information (S41).

Then, the communication terminal A makes a determination on the transmitted telephone number information (S42). That is, the determination program determines whether the transmitted telephone number information is a correct telephone number. That is, in this determination program, the telephone number given to the mobile phone terminal L is set and stored in advance as the number for authentication, and the stored telephone number and the transmitted telephone number are stored. It is determined whether or not matches. Therefore, if a call is made from a mobile phone terminal to which a telephone number other than the preset telephone number is assigned, the different telephone number is notified, and it is not determined that the telephone number is correct. If the transmitted telephone number information is a correct telephone number, the process proceeds to step S44, and if not, the process ends (S43).

In step S44, the operation type information sent from the mobile phone terminal L is analyzed, and a predetermined output signal corresponding to the operation type information is transmitted via the interface 26 (S44). For example, if the operation type information is a content for instructing engine start, a signal to instruct engine start is transmitted to an engine starting device (not shown). Then, the engine starting device starts the engine. On the other hand, if the operation type information is a content for instructing door lock release, a signal to instruct door lock release is transmitted to the door lock control device.

Further, a plurality of types of operations can be performed by the portable telephone terminal L.
As an example of the case of using the communication terminal A,
It is also conceivable that a plurality of telephone numbers are set in the communication unit 12 so that different operations can be performed for each telephone number. In other words, a first telephone number and a second telephone number are prepared as telephone numbers addressed to the communication terminal A, and any of these telephone numbers can be received. For example, when a call is made to the first telephone number, the engine is started, and when a call is made to the second telephone number, the door is unlocked. Specifically, similarly to the operation shown in FIG. 9, first, the telephone number of the caller is determined. And
If the telephone number is correct, it is determined which one of the plurality of telephone numbers is to be called, and an operation signal corresponding to the telephone number is output. For example, when a call is made to a telephone number corresponding to the engine start, a signal indicating an engine start is transmitted to an engine start device (not shown).

In the above description, it has been described that the telephone number information is received by the communication terminal A before the communication state is established, but it may be received after the communication state is established. .

In the above description, the number transmitted to the communication terminal A is described as the telephone number of the caller, that is, the telephone number of the portable telephone terminal L. However, the present invention is not limited to this. Any number may be used as long as it is a number that can specify that the call originated from the terminal L or a number that can specify that the user is a predetermined user. Each number in this case also functions as specific information. Such a number may be transmitted from the mobile phone terminal L by a predetermined operation. That is, in a state where the mobile phone terminal L and the communication terminal A are communicating, the user of the mobile phone terminal L presses the number or the like to transmit the communication terminal A side. The communication terminal A makes a determination on the number, and if the number is the same as a number registered in advance, an operation such as starting the engine is performed.

In the above description, the operation contents that can be instructed from the portable telephone terminal L have been described by taking the engine start and the door lock release as an example. However, the present invention is not limited to this.
Other operations such as a door lock for locking a door may be operations performed using a vehicle key, and may be other operations than operations performed using a vehicle key.

As described above, according to the present embodiment, the operation of starting the automobile engine and the operation of opening and closing the door lock can be performed using the portable telephone, so that the key itself of the vehicle is held. This eliminates the need and allows the vehicle to be driven without holding the key of the vehicle. Further, it is not necessary to separately hold a remote controller for starting the engine. Further, it is possible to spread the use form of the mobile phone.

It is needless to say that the portable telephone terminal L may be used for the portable terminal K in the first embodiment.
