Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication device, and more particularly to a mobile communication device capable of preventing unnecessary call / call operation in an incommunicable place and improving user convenience. Regarding

[0002]

2. Description of the Related Art In recent years, mobile communication devices such as mobile phone devices and car phone devices have become very popular. However, the mobile communication device has a drawback that communication is suddenly interrupted when the mobile station moves to a place where radio waves from the base station cannot reach.
For example, this is the case when an automobile equipped with an automobile telephone device enters a tunnel. In this case, when the user leaves the tunnel, the call procedure will be restarted from the beginning and communication will be restarted.However, when traveling in a mountainous area where the tunnel is continuous, the procedure for interrupting communication and calling again It becomes very inefficient because it will be repeated frequently.

Therefore, a system capable of giving advance notice to the user of the incommunicable area is desired. As such an attempt, in the mobile communication device described in JP-A-1-190136,
The service area of the base station, that is, the communicable area is displayed in the vehicle equipped with the telephone. By displaying the service area, the car telephone user can move the car so as not to leave the service area, and as a result, the interruption of communication can be avoided.

However, in this conventional apparatus, there is an inconvenience that a user driving a car must select a traveling route while checking the displayed service area.
In addition, in order to continue communication, it may be necessary to bypass the road, resulting in a wasteful driving. Further, since the displayed service area is fixed and does not take into consideration radio wave obstacles such as actual buildings and tunnels, there is a problem that communication is interrupted even within the service area where communication is supposed to be possible.

The problem that the displayed service area is fixed can be solved by, for example, the vehicle communication information providing apparatus disclosed in Japanese Patent Laid-Open No. 5-199167. This device is configured not to provide a fixed service area but to provide a communicable area obtained by combining an actual communication result and a navigation system. According to this vehicle communication information providing device,
According to the communicable area obtained by actual learning, it is possible to easily select a travel route for obtaining a better communication state.

[0006]

In the communication information providing apparatus for an automobile, it is possible to obtain a good communication state by selecting a traveling route, but there is a technical problem that has not yet been solved. For example, there is a problem that communication is eventually interrupted under a situation where a travel route cannot be freely selected such as an expressway. Therefore, the problem that the user has to repeat the communication procedure from the beginning every time the communication is interrupted at the time of use in the mountain area is not solved.

An object of the present invention is to solve the above problems,
It is an object of the present invention to provide a mobile communication device capable of performing efficient communication by notifying an incommunicable area and preventing useless call-out operation and call-in operation.

The present position detecting section 8 can be constructed so as to detect the position of the own vehicle based on, for example, a signal received by a GPS receiver, and the own vehicle can be detected based on detection information from a geomagnetic detection circuit, a distance sensor, a vehicle speed sensor and the like. It may also be composed of inertial navigation means for detecting the position of. The map information storage unit 9 and the designated range information storage unit 10 are CD-ROMs.
, IC card, etc., the warning unit 11 is L
The display unit 12, such as an ED and a speaker, can be configured by a CRT, a liquid crystal panel, or the like. The telephone 1 and the navigation device 2 are configured independently of each other, and a data bus 14 connects them.

Next, an example of the operation of the mobile communication device having the above configuration will be described. FIG. 3 shows the map information storage unit 9
It is the figure which displayed the designated range and the position of the own vehicle on the map by the information stored in FIG. The designated range Z is displayed based on the information indicating the incommunicable area registered in the designated range information storage unit 10, and the position A of the host vehicle is based on the information detected by the current position detection unit 8. Is displayed. The designated range Z may be a region that has been acquired in advance as a region (radio interference region) at which there is a risk of radio interference, or may indicate a region outside the service area of the car telephone. On this display screen, the host vehicle is located at the position A on the route R and goes straight in the direction of the arrow a. In the present embodiment, when the specified range Z on the route R and the relative position of the host vehicle have a predetermined relationship, the following processing is performed.

As a first process, when the designated range Z is approached by a predetermined distance, the warning unit 11 issues a warning to the user. Further, if a call is in progress at this point, an alarm, voice, or other preset signal is transmitted together with the warning or separately from the warning. With these warnings and alarms, it is possible to notify the other party that communication will soon be disabled.

As a second process, if the facsimile device 7 is transmitting image information at the time of issuing the warning, a specific message indicating that communication will soon be disabled is added to the transmitted image information. And send. On the other hand, when the image information is being received, the facsimile unit, that is, the output unit of the terminal itself is caused to output a specific message indicating that communication will soon be disabled. This message may be output overwritten on the received image or may be output as part of the result report. The message may be image information obtained by reading a message original prepared in advance, or may be a message stored in a storage unit such as a RAM by a key input from the operation unit or the like of the facsimile device 7.

As the third processing, when the designated range Z is approached, the navigation control unit 13 to the telephone control unit 6
A call prohibition signal, an incoming call prohibition signal, and a signal for turning off the power of the telephone set 1 are transmitted to. The telephone control unit 6 receives the call prohibition signal and the like, and executes a procedure for prohibiting call origination, call termination, and power-off of the telephone 1 and the facsimile apparatus 7. It should be noted that at least one of the call prohibition, the call reception prohibition, and the power-off processing can be selectively executed.

As a fourth process, after the outgoing call and incoming call are prohibited or the power is turned off, the outgoing call is made when the host vehicle is near or near the escape point from the designated range Z. Release the prohibition and turn on the power. Also, after approaching the specified range Z, or the specified range Z
After entering, the time until exiting from the designated range Z is predicted, and the prediction result is displayed on the display unit 12.

Next, each processing described above will be described in detail. First, a method of determining the positional relationship between the host vehicle and the designated range Z will be described with reference to FIG. In FIG. 4, the designated range Z exists on the route R on which the vehicle is traveling. The position information of the designated range Z is specified by the intersection coordinates of the grid set at a predetermined pitch on the map, and is represented by the longitude (x coordinate) and the latitude (y coordinate). Similarly, the position of the route R and the position of the own vehicle are represented by latitude and longitude. Particularly, in the present embodiment, it is assumed that the processing is performed based on the positional relationship of the host vehicle with respect to the designated range Z, and therefore, among the plurality of coordinate values representing the designated range Z, the coordinate value of the intersection with the route R is necessary for the processing. It will be useful information. Since both the route R and the designated range Z are represented by coordinate values, the intersection is actually represented by the coordinate value of the route R included in the designated range Z.

In the figure, the positions of the own vehicle are denoted by reference characters A, A1 and A.
2 and the intersections of the contour of the designated range Z and the route R are indicated by the symbols B and C. Further, a point on the route R that has left the designated range Z is indicated by a symbol D. Further, the symbol m is an intermediate point on the route within the designated range Z. The positions A, A1, A
2, B, C, D are represented by the coordinate values (x, y), and a serial number n for identifying each of a plurality of designated ranges and data indicating whether the designated range Z is inside or outside. Add M. That is, the position of the vehicle, each point within the specified range, and each point outside the specified range are coordinate (n, x,
y, M). The position outside the specified range Z is M =
The position inside 0 is represented by M = 1. The variable M is set when the position of the host vehicle is detected by the current position detecting section 8 by judging whether or not the position is within a designated range.

The distance L between the host vehicle and each point on the map is calculated as follows. For example, the distance to the point B or C within the specified range can be calculated by L ² = (x0, y0) ² + (x, y) ² . However, if the position of the own vehicle is (x0, y
0) and the positions of points B, C, D, etc. are (x, y).

In this embodiment, after the point B is specified,
When the vehicle approaches from the point B to the position of the distance d,
The scheduled processing such as the warning is executed. Further, in the present embodiment, when the host vehicle approaches the position of the distance d from the point B, the distance until passing through the designated range Z, that is, the distance L to the point C or D is obtained, and the point C or D is reached. Anticipate the time to.

Next, the processing of this embodiment will be described with reference to the flowchart. In FIG. 5, step S1
Then, the current position A of the host vehicle is detected by the current position detector 8 and is set as the coordinate value (x0, y0). In step S2, information (designated range map) representing the designated range is read from the designated range information storage unit 10. In step S3, the read designated range map is converted into coordinates (n, x, y, M) on the screen. In step S4, the value of the current position A is converted into coordinates (n0, x0, y0, M0) on the screen. Step S
At 5, information (road data) representing the route R on the screen is read and converted into coordinates (n, x, y) on the screen. In step S6, the coordinate value (n, x, y, M) of the route R included in the designated range Z is detected. That is, the road data included in the designated range Z indicated by the designated range map is calculated.

At step S7, the coordinate values (n, x, y,
The distance L from M) is calculated. Coordinate value (n, x, y, M)
Is a plurality of points on the route R included in the designated range Z, a plurality of distances L are calculated.

In step S8, it is determined whether or not the data M0 added to the coordinates of the own vehicle is "0", that is, whether the own vehicle is outside or within the specified range Z. Specified range Z
If it is determined that the vehicle is outside (M0 = 0), step S
In step 9, the coordinate (x, y) that minimizes the distance L is detected. In other words, the position where the distance L is the minimum is the specified range Z
Nearest point B to the own vehicle at the intersection of the outer edge of the vehicle and the route R
Therefore, the coordinate value (n1, x1,
y1, M1) is registered as the coordinate value of the point B (step S10).

In step S11, the distance L between the current positions A and B is calculated and set as a variable L1. In step S12, the output of the distance sensor, that is, the moving distance of the vehicle is read. The distance sensor is a well-known sensor for supplying data to the odometer of the automobile, and in the present embodiment, the movement distance after the processing of step S11 is detected by the output of this distance sensor. In step S13, it is determined whether or not the moving distance has reached the planned value Qm. Step S
At 14, the distance L between AB is calculated and set as a variable L2. In step S15, it is determined whether or not the variable L1 is larger than L2, and it is determined whether or not the host vehicle is approaching the point B.

When the host vehicle is not close to the point B, that is, when the determination in step S15 is negative, it is determined that the host vehicle is moving away from the closest designated range, and the process proceeds to step S1. The above-mentioned step S until approaching another designated range
The processing from 1 to step S15 is repeated.

If the determination in step S15 is affirmative, the flow advances to step S16 to calculate the coordinates of the current position A of the vehicle after moving the distance Qm. At step S17, the current location A
The distance L between B and B is calculated and set as a variable L0. In step S18, it is determined whether or not the distance L0 is smaller than the planned distance d from the point B. Own vehicle is point B
If the position has not reached the position of the distance d from, this determination is negative and the process proceeds to step S11. When the host vehicle has reached the position of the distance d from the point B, this determination is affirmative, and the process proceeds to step S19 to perform the processes A1, A2, A3, C.
Execute 1.

Next, the process A1 will be described with reference to FIG. In FIG. 6, in step S100, in order to notify that the point B has been approached, that is, the designated range has been approached, a warning is given by sound or display using the warning unit 11. The content of the warning is, for example, the display of a message indicating that the own vehicle will soon enter the designated range and the lighting of the warning light. Step S10
At 1, it is determined whether or not a facsimile call is in progress. If a call is in progress, the process proceeds to step S102, and a warning signal or a voice message is also sent to the call partner. The content of the message is warning information stored in advance. If no call is in progress, this process ends.

Next, the process A2 will be described with reference to FIG. In FIG. 7, step S200 is step S1.
The same warning as for 00 is issued. In step S201, it is determined whether or not facsimile communication is in progress. If communication is in progress, step S201
Proceed to 202 to determine whether the communication is a transmission. If it is determined that the image information is transmitted, the process proceeds to step S203, and it is determined whether the image information transmission is completed. If the image information transmission is not completed, it is determined in step S204 whether the image information is being transmitted. If image information is being transmitted, step S20.
Proceed to step 5 to suspend image information transmission. Step S20
At 6, a warning message is sent out. This message is registered in advance in the ROM or the like of the facsimile device 7 as image information, an example of which is shown in FIG. In step S207, image information for the portion after the temporary stop is transmitted.

In step S208, image information is transmitted. In step S209, it is determined whether the communication is cut off. If the communication is disconnected, the process proceeds to step S210, and it is determined whether the communication is disconnected based on the normal disconnection command. If the communication is normally interrupted, the process ends. If the communication is not normally interrupted, the process proceeds to step S214, and the interruption of the communication is registered as a communication record. This registration is performed by storing it in the RAM or the like of the facsimile device 7. The user of the facsimile device 7 can recognize the interruption on the way by the communication record and can execute the necessary procedure after the interruption such as the recalling procedure.

On the other hand, if the determination in step S202 is negative, it is determined that the facsimile is being received and the following processing is performed. In step S211, it is determined whether the communication is disconnected. If the communication is disconnected, the process proceeds to step S212, and it is determined whether the disconnection is normal. If the communication is normally interrupted, the process ends. If the communication is not normally interrupted, the process proceeds to step S213 and a message is added to the received image information. This message indicates that the reception was interrupted because the message entered the specified range. An example of this is shown in FIG.
(B). Further, FIG. 13 shows an example of a result of inserting a message into an actual received image.

The process A3 is executed as shown in FIG. In the figure, in step S300, outgoing and incoming calls are prohibited. In step S301, the wireless transmission / reception unit 4
And the power of the facsimile machine 7 is turned off.

Next, the process C1 will be described with reference to FIG. In this process C1, when the host vehicle is approaching the designated range Z, the distance and time from the host vehicle to the point C are calculated and displayed. In FIG. 9, step S40
At 0, the distance L between the current position A of the own vehicle and the coordinate values (n, x, y, M) of each point on the route R in the designated range is calculated.
In step S401, the coordinates (x,
y) is extracted. The point represented by these coordinates is the point C
(FIG. 4), and at step S402, the point C is registered as coordinates (n2, x2, y2, M2).

In step S403, the current position A is detected and converted into coordinates on the screen. In step S404, the distance L between the points A and C is calculated and set as a variable L3. In step S405, the moving speed H of the vehicle is detected. As the moving speed, a known speed detecting means for detecting the speed of the automobile is used. In step S406, point C
Predict the time T to reach. Time T is L3 / H
Can be calculated and obtained. In step S407, the time T is displayed on the display unit 12. Step S4
At 08, it is determined whether the host vehicle is inside or outside the specified range Z depending on whether the variable M0 added to the coordinate value indicating the current position is "1".

If the determination in step S408 is affirmative, it is determined that the host vehicle is inside the designated range Z and step S40 is performed.
In step 9, the current position A is detected and converted into coordinates on the screen. In step S410, the distance L between the points A and C is calculated and set as a variable L3. Step S411
Then, the output of the distance sensor, that is, the moving distance of the host vehicle after the process of step S410 is read. In step S412, it is determined whether the moving distance has reached the planned value Qm. In step S413, the distance L between the current positions A and C
Is calculated and set as a variable L5. In step S414, it is determined whether or not the variable L3 is larger than L5, and the vehicle is located at the point C.
Judge whether it is approaching (forward direction) or not (reverse direction).

If the host vehicle is moving in the forward direction, the process proceeds to step S415, the time required to reach point C is measured,
The result is displayed in step S416. The process of measurement and display is the same as the process of steps S403 to S407, so detailed illustration and description thereof will be omitted.
In step S417, it is determined from the variable M0 whether or not the host vehicle has escaped from the designated range Z. If it has escaped from the designated range Z, the process is terminated.

If the determination in step S414 is negative, the process proceeds to step S418, and it is determined whether or not the backward distance, that is, the distance from the current position to the point B is displayed. Whether or not to display this is determined by a preset instruction. When displaying the backward distance, the process proceeds to step S419, the time required to reach the point B is measured, and the result is displayed in step S420. This measurement and display processing is the same as the processing in steps S403 to S407. In step S421, it is determined from the variable M0 whether or not the host vehicle has escaped from the designated range Z. If it has escaped from the designated range Z, the process is terminated.

Subsequently, processings B1 and B when the own vehicle is determined to be inside the designated range Z in the determination in step S8
2 and C2 will be described. First, the process B1 is a process of monitoring whether the vehicle has passed the designated range Z and displaying a warning (guidance) when the user has passed the designated range Z. In FIG. 10, in step S500, the coordinates of the current position A are calculated.
The calculation of the current position A is performed in the same manner as steps S1 to S4 in FIG. 5, and thus detailed illustration and description thereof will be omitted. In step S501, it is determined whether or not the specified range Z is exited depending on whether or not the variable M is "0". If it is determined that the designated range Z is exited, the scheduled display is performed in step S502. The display is a message or a lamp display indicating that the designated range Z has been escaped.

Next, the process B2 will be described with reference to FIG. In this process B2, when the power goes out of the designated range Z, the power is turned off and the prohibition of incoming and outgoing calls is released. In the figure, in step S600, the coordinates of the current position A are calculated in the same manner as in step S500, and in step S601, it is determined whether or not the current position is out of the designated range. Then, if it is determined that the call comes out of the specified range, it is determined in step S602 whether incoming or outgoing call is prohibited, and if the determination is affirmative, step S603.
To remove the ban. In a succeeding step S604, it is determined whether or not the power source of the peripheral device is turned off. If the determination is affirmative, the power source is turned on in a step S605.

Next, the processing C2 will be described. Process C2
Then, when the host vehicle is already inside the specified range Z when the device is started up, the time until the vehicle exits the specified range Z is displayed. Here, if the host vehicle is inside the specified range Z when the device is started up, the steps S400 to S are performed.
There is a problem only by calculating the point C and displaying the time required to move to the point C as in the case of 402.
That is, the specified range Z in which the distance L is the maximum within the specified range Z
This is because the coordinate value of does not always indicate the point C, and the coordinate value of the designated range Z in which the distance is maximum depending on the position of the own vehicle is the point C or the point B. Therefore, in the process C2, the arrival time of the vehicle to the point C is displayed before the intermediate point of the designated range Z, and after the vehicle has moved before the intermediate point, the route outside the designated range Z is displayed. R
The point that is the closest to the current location, which is the upper point, is defined as point D, and the arrival time to point D is displayed.

In FIG. 4, if a point within the designated range Z where the vehicle has moved the planned distance Qm from the present location A1 is A2, and if the vehicle is in front of the intermediate point m of the designated range Z, the points A1 and points. The distance between points A2 and C should be larger than the distance between points C, but if the vehicle is moving ahead of the intermediate point m in the specified range Z, then point B is mistaken for point C. Therefore, the distance between the points A2 and C is smaller than the distance between the points A1 and C. Therefore, when the distance between the points A2 and C is smaller, it is determined that the host vehicle has moved ahead of the intermediate point m, and the arrival time to the point D is displayed.

Details of the process C2 are shown in the flowchart of FIG. In the figure, steps S700 to S70
2 performs the process for determining the point C similarly to steps S400 to S402. In steps S703 to S705, the point D that has left the designated range Z is calculated. These steps S703 to S705 are steps S7 and S9,
It is similar to S10.

In addition, steps S706 to S716 are the same as those of FIG. 9 except that step S418 is omitted, and the process of step S419 for the point B is shown in FIG.
4 is the same as step S410 to S419 of FIG. 9 except for the processing step S714 for the point D, the description thereof will be omitted.

Next, the main functions of the mobile communication device for performing the operation of this embodiment will be described with reference to the functional block diagram of FIG. 2, the same symbols as those in FIG. 2 indicate the same or equivalent parts. The approach position calculation unit 15 determines the approach position to the designated range based on the map information of the map information storage unit 9, the designated range information of the designated range information storage unit 10, and the position information of the own vehicle detected by the current position detection unit 8. The coordinates of the point B are calculated. Similarly, the escape position calculation unit 16 calculates the escape position from the specified range, that is, the coordinates of the point C or D, based on the map information and the like. Failure notice execution unit 17
Determines whether or not the vehicle has approached within a predetermined distance from the approach position.

When the own vehicle approaches the specified range, the failure notice execution section 17 notifies the warning section 11 of the occurrence of communication failure.
, The scheduled message is output to the display unit 12, and the telephone control unit 6 is notified. When the telephone control unit 6 receives the instruction from the failure notice execution unit 17, the telephone control unit 6 acquires the communication state from the facsimile device 7 and instructs the facsimile device 7 to add the image information corresponding to the transmission or reception. The telephone control unit 6 further instructs the facsimile device 7 to prohibit incoming and outgoing calls. Further, the failure notice execution unit 17 instructs the telephone control unit 6 to turn off the power of the telephone 1.

Further, the failure notice execution unit 17 gives an instruction to the time prediction unit 19 to predict the time until the vehicle passes the designated range. The time predicting unit 19 predicts the time until the end of passing the designated range based on the distance between the escape point and the own vehicle and the speed of the own vehicle. The estimated time is displayed on the display unit 12.
Is output and displayed.

The advance notice canceller 18 compares the position of the host vehicle with the coordinates of the escape point to determine whether the host vehicle has reached the escape point. When the host vehicle reaches the escape point, the warning unit 11, the display unit 12, the telephone control unit 6 and the like are output with a command for canceling the failure notice, canceling the prohibition of incoming and outgoing calls, and canceling the power-off of the telephone 1.

The instruction in the failure notice execution unit 17 is not limited to executing all of the above, and may be executed by selecting a treatment set in advance by system data or a program.
