Abstract

PROBLEM TO BE SOLVED: To prevent an accident caused by using a portable telephone unit inside of a public transportation and to protect public interest by detecting the moving velocity of the equipment and temporarily limiting the call function at the time of judging the establishment of a call restricting condition base on the moving velocity. SOLUTION: At the time of starting processing at the time of call-incoming, a moving velocity is first obtained from a velocity recognizing part 20. Successively, a moving velocity V and a previously set reference velocity for judgment Vref are compared with each other to judge whether the obtained moving velocity V is larger than the reference velocity for judgment Vref. Then when the obtained moving velocity V is larger than the reference velocity for judgment Vref, the portable telephone unit is switched to a mode for answering automatically. At the time of judging that a telephone number on a calling side is sent to this side, the telephone number on the calling side is recorded in an automatic answering part 70 and displayed on a display part 55. Then a recording processing is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device which is portable and can be used for telephone communication by wireless communication.

[0002]

2. Description of the Related Art Conventionally, portable telephones and PHS (Personal Handyphone / PHS) have been known.
2. Description of the Related Art There is known a portable telephone device that is portable and can communicate by wireless communication. The demand for these portable telephone devices is rapidly expanding because of the advantage that they can be used anytime and anywhere by being portable.

[0003] However, various disadvantages have been pointed out, for example, since a normal telephone call can be made even when the user is riding on a moving body such as a car or a train. For example, using a mobile phone device while driving a car may lead to an accident, or using a mobile phone device in a public transportation vehicle such as a train may cause noise to surrounding passengers. It is.

In order to solve such a problem with a conventional device, for example, a message "Let's not make a phone call while driving a car" is called, or "The mobile phone device itself is turned off and an external Don't take calls. " In other words, it is ultimately left to the self-management consciousness of the user's own manners. However, from the viewpoints of accident prevention and public interest protection, it is necessary to devise not to rely on such users' own management consciousness but to forcibly disable them.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. For example, the present invention is applicable to a case where it is estimated that the vehicle will be used in a car or in a public transportation vehicle such as a train. An object of the present invention is to provide a portable telephone device capable of preventing accidents and protecting public interest by forcibly restricting a call function.

[0006]

Means for Solving the Problems and Effects of the Invention The portable telephone device according to the first aspect of the present invention, which has been made to achieve the above object, is a portable telephone device capable of being carried and capable of communicating by wireless communication. And moving speed detecting means for detecting the moving speed of the apparatus itself, and determining means for determining whether a predetermined call restriction condition is satisfied based on the moving speed detected by the moving speed detecting means, When the determination means determines that the call restriction condition is satisfied, the communication device further includes a call restriction means for temporarily restricting a function of the call.

The moving speed detecting means may be configured to detect the moving speed based on position information obtained based on radio waves received from GPS satellites, for example. GPS is often used in car navigation systems and the like. In the case of a car navigation system, not only the moving speed but also the moving direction are calculated from the position information, but in the case of this device, the moving direction is unnecessary. . In addition, in the case of a car navigation system, altitude is measured in addition to latitude and longitude as position information. However, in the case of the present apparatus, there is no need for altitude.

If the moving speed can be detected, the GPS
Although the present invention is not limited to the detection method using a mobile phone, considering that the mobile phone device is incorporated in a mobile phone device, it is preferable to adopt a configuration in which a GPS radio wave is received to detect a moving speed because the device can be downsized to some extent. .

[0009] With regard to the determination by the determination means, for example, it is determined that the call restriction condition is satisfied when the detected moving speed is higher than the speed at which normal movement is possible only with human ability. It is possible to do. This is because the present invention does not restrict the call to, for example, using a telephone while walking, but is used while driving a car or in a public transportation vehicle such as a train as described above. This reflects that the call function is forcibly restricted when the situation is estimated. For this reason, it is conceivable to set, for example, about 20 to 30 km / h as the “normally movable speed” serving as the criterion. Of course, a lower speed or a higher speed may be set, but for example, 10 km /
When the speed is about h, it is a speed at which a person easily runs out even if the person runs, so consideration is necessary. For example, the duration may be considered. That is, 10 km / h
If a situation occurs in which such a situation continues for many minutes, it is determined that "the predetermined call restriction condition has been satisfied". This is because a person using the telephone may run temporarily, but it is considered that it will rarely last long.

[0010] Of course, the case where the speed is higher than the speed at which normal movement is possible only by human ability is an example. For example, when it is desired to limit the call while riding a bicycle,
It is only necessary to determine whether the speed is higher than the speed at which the bicycle can move normally. In that respect, 20-30km /
h is a reasonable point. Also in this case, a more appropriate determination can be made by taking the duration into consideration.

As described above, the portable telephone device of the present invention temporarily limits the call function when it is determined that the predetermined call restriction condition is satisfied based on the moving speed of the portable telephone device itself. In conventional equipment, it was left to the user's own awareness of self-management, but from the viewpoint of accident prevention and protection of public interest, instead of relying on such user's own awareness of management, However, there was a need to forcibly make the device unusable. Therefore, when a situation such as being used in driving a car or in a car of public transportation such as a train is estimated based on the traveling speed as in the present mobile phone device, the device itself is forcibly forced. Limiting the number of calls is effective in preventing accidents and protecting public interest.

Since the apparatus itself forcibly restricts the telephone call in a place where the user does not intend, a fourth aspect of the present invention is provided.
As shown in (1), a notifying means for notifying that the call is restricted by the call restricting means may be provided. For example, this is displayed on a display device, or the state is indicated by a notification lamp. In this way, for example, when the user tries to make a call, the reason why the call is restricted can be understood, so that the user can be distinguished from, for example, a failure, and the convenience is improved.

On the other hand, even when a call is received from the outside to the portable telephone device, the telephone call is restricted. In other words, if the device has a predetermined answering machine function, if there is an incoming call to the own device while the call is restricted, the call is automatically connected by the answering machine function and the call is restricted. The caller responds to the caller. In this way, it can be seen that it is not impossible for the caller to make a call because the other party is absent. Further, it is more convenient to have a so-called "answering machine" function as a recording means for recording a message.

The "mobile phone device" of the present invention has at least portability and a telephone function, and does not mean only a so-called mobile phone. In other words, it goes without saying that even if a handset for PHS is included, or a system with a different name is constructed in the future, the present invention can be similarly applied to a portable telephone device.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of a mobile phone device 1 as an embodiment to which the present invention is applied.

A telephone antenna 35 is also provided so as to be able to enter and exit the main body 2 of the portable telephone device 1. The transmitting / receiving unit 30 connected to the telephone antenna 35 performs transmission / reception to / from the wireless communication telephone network via the telephone antenna 35 and transmits the voice input to the voice input unit 40 as a wireless signal. Alternatively, the received radio signal is uttered from the sounding unit 45 as voice.

The key input unit 50 inputs an instruction from a user of the portable telephone device 1 through a plurality of keys provided. The display unit 55 includes a liquid crystal display and its drive circuit, and displays the state of the mobile phone 1 and various messages. The answering machine 70 stores a response message (hereinafter, referred to as an OGM: Outgoing Message) to be sent to the calling party when the answering machine is set to the answering machine mode, and a telephone number of the calling party. It is composed of a dynamic RAM (DRAM) or the like, and performs alternative reception of a telephone call on behalf of a user. Message recording unit 7
Reference numeral 5 denotes an incoming message (hereinafter referred to as I) sent from the calling side when the substitute answering is performed by the answering machine 70.
CM: Incoming Message. ) Etc. are recorded.

In response to an instruction from the key input unit 50, the control unit 10 changes the settings stored in the internal memory, and calls another portable telephone device via the transmission / reception unit 30. Then, the transmission / reception unit 30 performs communication processing with the other party. When it is determined that the call has been received via the transmission / reception unit 30, the sound generation unit 45 or the vibration unit 60 is notified to the user.
Is driven to notify the user of the incoming call, and when a response instruction is given via the key input unit 50, the transmitting / receiving unit 30 is made to perform communication processing with the other party. Furthermore, when the so-called “answering machine” mode is set, the OGM for alternative reception is read from the answering machine corresponding unit 70 and the transmitting / receiving unit 3
0 to another mobile phone device or the like. When the ICM is received from the other party, the message is recorded in the message recording unit 75.

The sound generator 45 has a drive circuit and a speaker, and the vibrator 60 has a drive circuit and a vibrator. When an output signal is input from the control unit 10 to the drive circuit of the sound generation unit 45, a sound set to a predetermined frequency is output from a speaker according to the output signal. When an output signal is input from the control unit 10 to the drive circuit of the vibration unit 60, the vibrator vibrates according to the output signal, and the vibration causes the main body 2 of the mobile phone device 1 to vibrate.

The control unit 10 is configured as a microcomputer, and includes a CPU, a ROM, a RAM, a backup R
It has an AM, a bus line, an I / O, and the like. Next, a process related to the call restriction executed in the mobile phone device 1 will be described with reference to flowcharts of FIGS.

FIG. 2 is a flowchart showing a main process executed by the control unit 10 of the portable telephone device 1. When the execution of this processing is started, first, in step (hereinafter simply referred to as S) 10, it is determined whether or not a call signal is received (whether there is an incoming call), and it is determined that there is an incoming call. In this case (S10: YES), in subsequent S20, a predetermined incoming call process is executed. This incoming call process will be described later, and the description of the flowchart of FIG. 2 will be continued.

If a negative determination is made in S10, that is, if it is determined that there is no incoming call, the process proceeds to S30 and the key input unit 5
It is determined whether or not a number has been input through “0”. If there is no number input (S30: NO), the process returns to S10, but if there is a number input (S30: YES), the subsequent S4
At 0, the entered number is stored.

Then, in S50, the key input unit 50
It is determined whether or not the call key has been turned on. If the call key has been turned on (S50: YES), the flow shifts to S60 to execute a predetermined calling process. This is because, when making a call on the mobile phone 1, the user inputs a telephone number first, and then turns on the call key to make a call using the input telephone number. is there. This transmission process will be described later, and the description of the flowchart of FIG. 2 will be continued.

If a negative determination is made in S50, that is, if it is determined that the call key has not been turned ON, the flow shifts to S70, and it is determined whether or not a timeout has occurred. If it is not time-out (S70: NO), the process returns to S30 and waits for further input of a number.
0: YES), and the process returns to S10. This is a configuration in which the mobile phone device 1 inputs a telephone number first and then turns on the call key to make a call with the input telephone number as described above, so that the number input is started. After that (S30: YES), if the call key is not turned on after a predetermined time (S70: YES), the series of processes is invalidated.

Next, the incoming call processing routine executed in S20 will be described with reference to the flowchart of FIG. When the process at the time of incoming call is started, first, the moving speed V is acquired from the speed recognition unit 20 in S110. As described above, the speed recognizing unit 20 receives the radio waves of three or more receivable GPS satellites 100 among the active GPS satellites 100 via the GPS antenna 25, and determines the known positions of the GPS satellites 100. Each GPS satellite calculated from received radio waves
The position of the receiving point is obtained based on the distance between the receiving points,
Temporarily store as latitude / longitude data. Then, the moving speed is calculated from the latitude / longitude data similarly acquired at another timing. Therefore, the control unit 10
The moving speed V is obtained from the speed recognition unit 20.

In the following S120, the moving speed V obtained in S110 and the reference speed Vre set in advance are determined.
f, and the acquired moving speed V is the reference speed V for determination.
It is determined whether it is larger than ref. The reference speed Vref for determination is set from the viewpoint of, for example, a speed at which a person can move only with the ability of a person.
It is conceivable to set about 0 km / h.

If the acquired moving speed V is higher than the reference speed for reference Vref (S120: YE)
S), switching to the mode for answering machine response (S13)
0). In subsequent S140, it is determined whether or not the calling telephone number has been sent together with the predetermined incoming signal. If it is determined that the calling telephone number has been sent (S1
40: YES), in S150, the calling telephone number is received and recorded in the answering machine corresponding section 70, and the calling telephone number is displayed on the display section 55.

Thereafter, the flow proceeds to S160 to close the telephone line, and in S170, the OGM stored in the answering machine corresponding section 70 is transmitted to the telephone line. And S180
Execute the recording process in. The recording process routine executed at 180 will be described with reference to the flowchart of FIG.

When the main recording process is started, first, at S41
At 0, it is determined whether the calling telephone number has been received in S130 described above and stored in the answering machine corresponding section 70. If it is determined that the calling telephone number has been received (S410: YES), the process proceeds to S4.
At 20, an IC for recording the calling telephone number from now on
A process for storing in the answering machine corresponding unit 70 as attribute information (hereinafter, referred to as ICM attribute information) corresponding to M on a one-to-one basis is executed.

If the process of S420 is completed or if it is determined in S410 that the calling telephone number has not been received (S410: NO), the process proceeds to S430.
Start recording the incoming ICM from the telephone line. In this process, an analog voice signal from the calling side is converted into a digital voice signal and captured, and data (recording data) corresponding to the voice signal is stored in the message recording unit 75.
It is executed in such a procedure.

Then, in S440, the IC being recorded is
Whether or not the state where no sound is included in M has continued for a predetermined time or longer, in other words, the signal being recorded is longer than a predetermined time,
It is determined whether the signal is a non-voice signal. The non-speech signal determined here is a signal such as a non-speech signal containing no sound, a single-tone continuous signal, or a single-tone repetition signal (visit tone). Is determined to be affirmative when the information has continuously arrived for a predetermined time or more.

If it is determined in S440 that the non-speech signal has not continued for a predetermined time or more (S44).
0: NO), and proceeds to S450 to determine whether or not a preset recording time has elapsed. If it is determined that the recording time has not elapsed (S450: NO), the process proceeds to S450.
Returning to 440, the processes of S440 and S450 are repeated.

On the other hand, if it is determined in S440 that the non-speech signal has continued for a predetermined time or more (S440: YE
S), the process proceeds to S490, and the recorded data of the non-voice signal portion is deleted from the message recording unit 75. here,
When a predetermined time or more has elapsed from the beginning of the ICM due to the non-voice signal, no recording data of the ICM remains, but the fact that the recording of the ICM has been performed is indicated by the message recording unit 7.
5 is stored.

When the process of S490 is executed, if it is determined in S450 that the recording time has elapsed (S450: YES), the process proceeds to S500 to release the telephone line. Then, in subsequent S510, it is determined whether or not the recording data of the ICM recorded this time is in message recording section 75, and if it is determined that there is recording data (S510: YES), the recording processing is directly performed. finish.

At S510, the ICM recorded this time
(S510: N)
O), the process proceeds to S520, in which the soundless flag in the ICM attribute information is set, and the process ends. The no-sound flag is a flag indicating that the corresponding ICM was once recorded but was a non-speech signal for a predetermined time or more from the beginning, and that all recorded data was deleted from the message recording unit 75. It is.

When this recording process is completed, S19 in FIG.
Move to 0. In S190, a sound of a predetermined frequency is generated from the sound generator 45, or the main body 2 of the mobile phone device 1 is vibrated by the vibration of the vibrator 60 to notify that there is an incoming call. Then, in subsequent S200, predetermined information (for example, arrival time, presence / absence of a recorded message, etc.) regarding the called party is displayed on display unit 55, and the incoming call processing is terminated.

On the other hand, if a negative determination is made in S120, that is, if the acquired moving speed V is equal to or lower than the reference speed for reference Vref, the flow shifts to S210 to sound a ringing tone. In subsequent S220, it is determined whether or not the other party is disconnected. If the other party is disconnected (S220: YE
S). The flow shifts to S280, where the ringing tone is stopped, and the incoming call processing ends.

If a negative determination is made in S220, that is, if the other party has not been disconnected, the flow shifts to S230 to determine whether or not the call key has been turned on. If the call key has not been turned on, the flow returns to S210 to return to S210 and subsequent steps. Repeat the process. When the call key is turned on (S23)
0: YES), proceed to S240 to stop the ringing tone,
In S250, the telephone line is closed. This enables a call.

Then, in subsequent S260, it is determined whether or not the user has turned on the end key, and the process waits until the end key is turned on. When it is determined that the end key has been turned on (S260: YES), it is determined that the user's call has ended, and the telephone line is released in the next S270, thereby terminating the final incoming call process.

After the end of the incoming call process, the process returns to S10 of FIG. Next, FIG.
The outgoing call process in S60 will be described with reference to the flowchart of FIG.

When the transmission process is started, first, at S610
To obtain the moving speed V from the speed recognition unit 20. The following S
At 620, the moving speed V acquired in S110 is compared with a preset reference speed for reference Vref, and it is determined whether or not the acquired moving speed V is higher than the reference speed for reference Vref. These are the same as the processing in S110 and S120 in the above-described incoming call processing.

If the acquired moving speed V is higher than the reference speed for reference Vref (S620: YE)
S) The display unit 55 displays that it is in the call restriction state because it is moving at high speed. In subsequent S640, it is determined whether a predetermined time has elapsed (whether a timeout has occurred).
If it is not time-out (S640: NO), S6
50, the moving speed V is acquired.
It is determined whether or not the moving speed V obtained at 50 is higher than the reference speed for reference Vref. These are the S
This is the same as the processing in 610 and S620.

The obtained moving speed V is the reference speed Vr for judgment.
If it is larger than ef (S660: YES), S6
Returning to 40, it is determined whether or not a timeout has occurred. If the timeout occurs as it is (S640: YE
S), the main transmission process is terminated as it is, and the process returns to S10 of FIG. 2 to be in an incoming call waiting state.

On the other hand, if a negative determination is made in S660 before the timeout occurs, that is, the acquired moving speed V
Is less than or equal to the reference speed for reference Vref, S6
Move to 70. Also, in the case of a negative determination in S620, the process similarly proceeds to S670. In S670, a call is made with the input telephone number (the number stored in S40 of FIG. 2). That is, when the moving speed V obtained in S610 is equal to or lower than the reference speed for reference Vref, and when the moving speed V obtained in S610 is higher than the reference speed for reference Vref (S620: YES), before the timeout occurs. If the reference speed Vref is equal to or lower than the reference speed Vref, a call is made to the outside using the input telephone number, and the process proceeds to a normal call process.

After the call is made in S670, it is determined in S680 whether or not the connection has been made. If the connection cannot be made (S680: NO), it is determined in S690 whether or not the end key has been turned on. While the end key is not turned on (S690: NO), the process returns to S680, but the end key is turned on.
If this is done (S690: YES), the main outgoing call process is terminated as it is, and the process returns to S10 in FIG. 2 to be in an incoming call waiting state.

On the other hand, if the connection has been established (S680: Y
ES), and proceeds to S700 to close the telephone line. This enables a call. And the following S71
At 0, it is determined whether or not the user has turned on the end key, and the process stands by until the end key is turned on. If it is determined that the end key has been turned on (S710: YES),
When it is determined that the user's call has been completed, the telephone line is released in the subsequent S720, and the process at the time of the outgoing call is terminated, and the process proceeds to S720 in FIG.
Then, the process returns to step 10 to wait for an incoming call.

As described above, the portable telephone device 1 of the present embodiment
Temporarily restricts the call function when it is determined that a predetermined call restriction condition is satisfied based on the moving speed V of the device itself. In other words, even if an incoming call is received from outside, the user will not be notified of the call without ringing,
In addition, no attempt is made to place a call when attempting to make a call to the outside. In conventional devices, whether or not to use a mobile phone device was left to the user's own self-care awareness, but from the viewpoint of accident prevention and public interest protection, such Rather than relying on the user's own management consciousness, there was a need to devise ways to forcibly disable use. Therefore, when the moving speed is high to some extent as in the mobile phone device 1, that is, when a situation in which the mobile phone device is used, for example, while driving a car or in a public transportation vehicle such as a train, is estimated. It is effective in preventing accidents and in protecting public interests because it forcibly restricts calls.

In the above-described embodiment, the reference speed Vref for determination is set to about 20 to 30 km / h from the viewpoint of the speed at which the person can move only with the ability of a person. This is because the present invention does not restrict the call to, for example, using a telephone while walking, but is used while driving a car or in a public transportation vehicle such as a train as described above. This is due to the fact that the call function is to be forcibly restricted when the situation is estimated. Of course, a lower speed or a higher speed may be set, but for example, 10 km /
When the speed is about h, it is a speed at which a person easily runs out even if the person runs, so consideration is necessary. For example, the duration may be considered. That is, 10 km / h
If a situation occurs in which such a situation continues for many minutes, it is determined that "the predetermined call restriction condition has been satisfied". This is because a person using the mobile phone device 1 may run temporarily, but it is considered that it rarely runs long.

Of course, the case where the speed is higher than the speed at which normal movement is possible only with human ability is an example. For example, when it is desired to limit the call while riding a bicycle,
It is only necessary to determine whether the speed is higher than the speed at which the bicycle can move normally. In that respect, 20-30km /
h is a reasonable point. Also in this case, a more appropriate determination can be made by taking the duration into consideration.

Further, since the portable telephone device 1 forcibly restricts a call at a place where the user does not intend, as described in S630 of FIG. 5, it is assumed that the call is restricted. If the display is made on the display unit 55, the reason why the call is restricted when the user tries to make a call can be understood, so that it is possible to distinguish it from, for example, a failure and to improve the convenience.

The "mobile phone device" of the present invention has at least portability and a telephone function, and does not mean only a so-called mobile phone. In other words, it goes without saying that even if a handset for PHS is included, or a system with a different name is constructed in the future, the present invention can be similarly applied to a portable telephone device.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications and improvements can be made without departing from the spirit of the present invention. Some things are easily speculated.
