[0002]
[Prior art]
2. Description of the Related Art The spread of mobile phone terminals has made it possible to make calls at places other than places where fixed telephones are installed. However, some mobile phone handset owners are making public calls, such as on a train, in a public place that may cause inconvenience to others. Various proposals have been made.
[0003]
For example, in Japanese Patent Application Laid-Open No. 2000-125339, the number of location registration requests for a mobile phone terminal in a standby state within a certain period of time is detected, and the moving speed of the mobile phone terminal is determined based on the number. ing. During high-speed movement, the mobile phone terminal does not set the incoming call mode to the ringing mode but to the mode of vibrating by the vibrator or the mode of answering machine recording. By this, when there is an incoming call to the mobile phone terminal of a person riding a public institution such as a train or a bus, it is possible to prevent the ringing sound from affecting the surrounding people and Try to keep a call absent.
[0004]
In Japanese Patent Application Laid-Open No. Hei 10-190557, a moving speed of a mobile phone terminal is determined stepwise, and based on the result, an incoming call is ignored, a call is restricted, or a stored warning message is transmitted to a radio speaker. And sound a buzzer.
[0005]
Further, in Japanese Patent Application Laid-Open No. H11-18159, speed information of a mobile phone terminal is obtained using a GPS (Global Positioning System) device, and using this information, a call is made in a predetermined case where the speed is higher than the moving speed of a pedestrian. Operation is temporarily stopped. This makes it possible to operate mobile phone terminals in consideration of public manners.
[0006]
In Japanese Patent Application Laid-Open No. H11-127469, the moving speed of a mobile phone terminal is detected, and when it is determined that the mobile phone terminal is moving at high speed, a call disconnection signal is transmitted to the target mobile phone terminal. In such a case, the restrictions on outgoing and incoming calls are released.

BEST MODE FOR CARRYING OUT THE INVENTION
[0026]
【Example】
Hereinafter, the present invention will be described in detail with reference to examples.
[0027]
FIG. 1 shows an outline of a circuit configuration of a mobile phone terminal according to an embodiment of the present invention. The mobile phone terminal 101 has a CPU (central processing unit) 102 mounted thereon. The CPU 102 is connected to a ROM 104, a RAM 105, an EEP-ROM 106, a wireless control unit 107, and a channel codec user interface composite LSI 108 via a bus 103. Here, the ROM 104 is a read-only memory that stores a program for executing control of each unit of the mobile phone terminal 101. The RAM 104 is a working memory for temporarily storing data for various controls, and is constituted by a random access memory.
[0028]
An electrically erasable and programmable read only memory (EEP-ROM) 106 is an electrically erasable programmable read-only memory. The wireless control unit 107 controls the wireless unit 111 that performs wireless transmission and reception. A channel codec user interface complex LSI (large scale integrated circuit) 108 includes an A / D converter, a D / A converter, various filters, and a TDMA-TDD required for processing an audio signal and processing a modulation / demodulation signal in a baseband. (Time Division Multiple Access-Time Division Duplex) is a large-scale integrated circuit. By mounting all these circuits on one chip, it is possible to reduce the cost, reduce the current consumption, and reduce the size of the terminal. I have. The channel codec user interface composite LSI 108 is connected to a beep horn 112 for outputting a beep sound, and a speaker 113 and a microphone 114 for a call. A connector 116 is connected to the CPU 102 via a serial line driver 115.
[0029]
Here, TDMA (Time Division Multiple Access) divides signals at the same carrier frequency so that signals do not overlap in time, and transmits signals intermittently (called a burst signal) within an assigned time width. TDD (time division bidirectional) is a method in which one line is time-divided, a specific time zone is allocated to a communication party, and bidirectional communication is performed in the allocated time zone. being called.
[0030]
FIG. 2 shows a memory map of the EEPROM of this embodiment. The memory area 121 indicated by the address “0300” of the EEP-ROM 106 has the bit D₀~ Bit D₇, Consisting of 8 bits, of which bit D₀Indicates on / off of the nuisance call prevention function (MEI). That is, this bit D₀Is "1", the nuisance call prevention function is enabled, and bit D₀Is "0", the nuisance call prevention function is invalidated. Bit D₀Whether "1" is set to "0" or "0" is determined by setting a dedicated jig in the connector 116 shown in FIG. 1 according to the contract at the time of purchase of the portable wireless terminal. This will be described later in detail.
[0031]
FIG. 3 shows details of the configuration of the channel codec user interface composite LSI shown in FIG. 1 and how it is connected to peripheral circuits. The codec 131 in the channel codec user interface complex LSI 108 is connected to the wireless control unit 107 via the wireless control unit / codec line 132, and the path control register 133 and the gain control register 134 are connected to the bus 103. Further, the output side of the beep sound amplifier 135 in the channel codec user interface composite LSI 108 is connected to the beep horn 112, and the output side of the audio output amplification amplifier 136 is connected to the speaker 113. Further, the audio input amplification amplifier 137 is connected to the microphone 114.
[0032]
The codec 131 is a circuit that converts voices and images handled by the mobile phone terminal from analog data to digital data and vice versa. The audio signal that has passed through the audio input amplification amplifier 137 is directly input to the codec 131, converted into a digital signal, encoded, and sent to the wireless control unit 107. A tone generator 141 is provided in the channel codec user interface composite LSI 108, and a tone amplifier 143 is connected to an output side of the composite LSI 108 via a first path switch 142. The tone signal 144 amplified by the tone amplifier 143 is input to the mixer 145.
[0033]
On the other hand, the audio signal 146 output from the codec 131 via the wireless control unit 107 is input to the audio amplifier 148 via the second path switch 147 and amplified. The amplified audio signal 149 is input to the mixer 145 and mixed with the tone signal 144. The output of the mixer 145 is input to the audio output amplifying amplifier 136, and the amplified signal is input to the speaker 113.
[0034]
The first and second path switching switches 142 and 147 are connected to the first bus switching control switch line 151 or the second bus switching control switch line 152 connected to the path control register 133, and correspond to these. The switching control of the contacts is performed depending on the object. The first path changeover switch 142 switches the output of the tone generator 141 to one of the two contacts, and switches between the tone amplifier 143 and the beep sound amplifier 135 described above. Is
[0035]
The gain control register 134 is connected to the tone amplifier 143 by a tone generator side amplifier control line 154, and controls the amplification factor. The gain control register 134 is connected to the audio amplifier 148 by a codec-side amplifier control line 155, and controls the amplification factor.
[0036]
As described above, various control programs are stored in the ROM 104 (see FIG. 1) of the mobile phone terminal system according to the present embodiment having the above-described configuration, and the manner of the owner of the mobile phone terminal 101 can be increased. It can be planned. This will be described below.
[0037]
FIG. 4 shows the flow of setting and canceling the nuisance call prevention function for the EEP-ROM. When the power of the mobile phone terminal 101 shown in FIG. 1 is turned on, the CPU 102 checks the connection status of the connector 116, and when a jig for setting and canceling the nuisance call prevention function is detected (step S201: Y ), And shift to the mode of setting and canceling the nuisance call prevention function. In other cases, other work is executed (step S202). The jig is owned by a management company that manages the charge of the portable wireless terminal, and the administrator sets and cancels the nuisance call prevention function at the time of contract and when the contract is changed.
[0038]
In the mode of setting and canceling the nuisance call prevention function, the CPU 102 reads the specific memory area 121 indicated by the address “0300” (see FIG. 2) of the EEP-ROM 106 (step S202). Then, the current settings are displayed on a liquid crystal display (not shown) (step S203). Bit D shown in FIG.₀Is initially "1" (the nuisance call prevention function is enabled). If this is changed to "0" (the nuisance call prevention function is disabled) by a contract, the administrator of the management company operates a key on a jig (not shown) to change the content. The CPU 102 sets bit D₀(Step S204: Y), the bit D₀Is inverted (step S205). Then, the changed content is displayed on the liquid crystal display (step S203). Further changes can be made in this state (step S204). In the case where the user simply confirms the content without changing the content, the user selects the end of the process using a key on the jig (step S206: Y).
[0039]
In the mobile phone terminal system according to the present embodiment, when the nuisance call prevention function is disabled, the charge discount service for manners recommendation cannot be received, and the nuisance call prevention function is enabled. In comparison with, calls are made at higher rates during high-speed movement, which will be described later.
[0040]
Figure 5 shows the unwanted call prevention functionDisabledIt shows the flow of monitoring and control during a call when it is set. The CPU shown in FIG. 1 monitors whether a call is in progress (step S221). If a call is in progress (Y), it is determined whether the mobile phone terminal 101 itself has started high-speed movement (step S222) or has ended high-speed movement (step S223). Here, the high-speed movement refers to a case where the person carrying the mobile phone terminal 101 moves at a speed higher than the speed of walking or riding a bicycle at a normal speed.
[0041]
The determination as to whether or not the high-speed movement has started or ended is made independently by a movement speed determination process (not shown). For the detection of the high-speed movement, for example, the technology already disclosed in Japanese Patent Application Laid-Open No. 2000-125339 and Japanese Patent Application Laid-Open No. 11-18159, which are pointed out as the prior art of the present invention, can be used. Detailed description is omitted.
[0042]
If it is determined that the high-speed movement has started (step S222: Y), the alarm processing described in detail below is started (step S224). On the other hand, when the high-speed movement is stopped such as when the user gets off the train and starts walking (Step S222: N, Step S223: Y), a process for stopping the alarm process is executed (Step S222). S225).
[0043]
FIG. 6 shows the contents of the alarm start processing shown in step S224 of FIG. When the mobile phone terminal 101 starts moving at a high speed during a call, the CPU 102 first sets the minimum gain in the gain control register 134 shown in FIG. 3 (step S241). Next, predetermined tone data is set in the tone generator 141 shown in FIG. 3 (step S242). Here, the tone data is data representing an alarm sound, and it is also possible for an administrator to talk with the purchaser at the time of contract and select the content in advance.
[0044]
After setting the tone data, the CPU 102 sets data for turning on the path in the path control register 133 (step S243). There are two types of data for turning on the path according to the path of the path. One is a path for inputting a tone output from the tone generator 141 to the beep amplifier 135 via the first path switch 142. When this path is selected, the beep horn 112 outputs an alarm sound. However, since the gain is initially set to the minimum value in step S241, the alarm sound output from the beep horn 112 at the initial stage is at the lowest level.
[0045]
If the data for turning on the path selects another path, the tone output from the tone generator 141 is input to the tone amplifier 143 via the first path changeover switch 142, and the amplified tone is output. Input to the mixer 145. In this case, a tone is mixed with the audio signal 146 output from the codec 131 and is output from the speaker 113 as a mixed sound. Also in this case, since the gain is initially set to the minimum value, the level of the alarm sound output from the speaker 113 in the initial stage is low.
[0046]
After performing such initial settings, the CPU 102 executes a process of gain step control for switching the output gain of the alarm sound with the passage of time (step S244). This will be described later. It should be noted that which path the alarm sound is output may be determined at the time of contract, or the CPU 102 may randomly select the alarm sound by random number processing or the like.
[0047]
FIG. 7 shows the flow of the alarm stop processing shown in step S225 of FIG. In the alarm stop processing, the CPU 102 cancels (off) the setting (on) of the path for the path control register 133 performed in step S243 of FIG. 6 (step S261).
[0048]
FIG. 8 specifically shows the gain step control shown in step S244 of FIG. When the gain step control is started, the CPU 102 first sets a predetermined value as the time measured by the timer (step S281). This value may be simply read from the ROM 104, or the history of the owner of the mobile phone terminal 101 may be taken, and a value such that the time measured gradually decreases when the manner of violation of manners is strong is selected. It may be. Such a value can be managed by the network for each mobile phone terminal 101, and a value corresponding to the manner violation can be periodically set from the base station side. When the timer is configured by a counter (not shown) that counts clocks, the number of clocks corresponding to the counted time is set.
[0049]
After the setting of the clocking time, the clocking operation is started (step S282). When the clocking is completed (Step S283: Y), the value is reset (Step S284), and the gain value “G” is changed to the next largest gain value “G + 1” (Step S285). Then, that value is the maximum value of Gen-y “G_max(Step S286). If the maximum value has been reached (Y), that state is maintained (end). If the maximum value has not been reached (step S286: N), the process returns to step S282, and the timekeeping operation is started with a new gain.
[0050]
With such a gain control, the loudness of the alarm sound is initially minimal, but becomes loud each time a predetermined timekeeping operation is completed. Therefore, if the owner continues the call in violation of the manners, if the beep horn 112 outputs a warning sound, the sound will gradually become loud and draw the attention of the surrounding people, and the call will be terminated. You have to let it. Further, since the alarm sound is transmitted from the microphone 14 to the other party, not only is the call difficult, but also the other party is likely to tilt in a direction to stop the call.
[0051]
On the other hand, when the alarm sound is mixed with the speaker 113, as the alarm sound becomes louder, it becomes difficult to hear the other party's talk, and similarly, the call must be terminated early. Moreover, in any case, the cost of making a call while moving at high speed is a relatively high call charge. Therefore, from the viewpoint of saving call charges, there is a high possibility that the contract is changed and the setting is shifted to a setting in which a call cannot be made during high-speed movement.
[0052]
First modification
[0053]
In the embodiment described above, the call during high-speed movement is enabled according to the contract content, and the volume of the alarm sound is gradually increased instead. However, it is also possible to perform processing to forcibly disconnect the call instead. is there.
[0054]
FIG. 9 shows a first modification of the present invention. In FIG. 9, the same parts as those in FIG. In the first modification, the gain value “G” is changed to the next largest gain value “G + 1” (step S285), and the resulting gain is changed to a predetermined threshold value “G”._TH(Step S301: Y), the line is forcibly disconnected (step S302).
[0055]
Second modification
[0056]
FIG. 10 shows the contents of the control of the volume at the time of transmission in the second modified example of the present invention. In the above embodiment, an alarm sound is output to the holder moving at high speed in violation of manners, and the volume of the alarm is controlled. In the second modification, the gain of the transmitted voice is adjusted. That is, by controlling the amplification factor of the audio input amplification amplifier 137 or the attenuation factor of the attenuation attenuator shown in FIG. 3, the volume sent to the wireless control unit 107 is set to a normal level at first, and is gradually attenuated. I have to speak loudly according to. As a result, it is difficult to keep talking unless you are in an emergency.
[0057]
In the second modification, first, the CPU 102 sets a predetermined value as the time measured by the timer as in step S281 of FIG. 8 (step S321). This value may be simply read from the ROM 104, or the history of the owner of the mobile phone terminal 101 may be taken, and a value such that the time measured gradually decreases when the manner of violation of manners is strong is selected. It may be. The value may be managed by the network for each mobile phone terminal 101, and a value corresponding to the manner violation may be periodically set from the base station side.
[0058]
When the setting of the clocking time is performed, the clocking operation is started (step S322). When the clocking is completed (Step S323: Y), the value is reset (Step S324), and the gain value “G” is changed to the next smaller gain value “G + 1” (Step S325). Then, the value is the minimum value of Geny “G_min(Step S326), and if the minimum value has been reached (Y), that state is maintained (END). The minimum value may be such that the signal level is “0”. If it has not reached the minimum value (step S326: N), the process returns to step S322, and the timekeeping operation is started with a new gain.
[0059]
Third modification
[0060]
The control according to the third modification is achieved by gradually decreasing the amplification factor of the audio output amplification amplifier 136. This makes it difficult to hear the voice of the other party over time. The control of this modified example is realized by exactly the same processing as that shown in FIG. 10 except that the audio output amplifying amplifier 136 is a control target, and therefore is not shown.
[0061]
Fourth modification
[0062]
FIG. 11 shows the contents of the control of the volume of the alarm sound in the fourth modified example of the present invention. In the fourth modified example, unlike the alarm start processing shown in FIG. 6, by outputting a loud alarm sound from the beep horn 112, it is possible to make the surroundings aware of the manner violation and continue the call. Making it difficult.
[0063]
That is, when the mobile phone terminal 101 (see FIG. 1) starts moving at a high speed during a call, the CPU 102 first sets the maximum gain in the gain control register 134 shown in FIG. 3 (step S341). Next, predetermined tone data is set in the tone generator 141 shown in FIG. 3 (step S342). Here, the tone data can be selected in advance by the administrator discussing with the purchaser at the time of contract.
[0064]
After setting the tone data, the CPU 102 sets data for turning on the path in the path control register 133 (step S343). In this case, a path for inputting the tone output from the tone generator 141 to the beep amplifier 135 via the first path switch 142 is set. As a result, the beep horn 112 outputs an alarm sound at the maximum volume. The holder of the mobile phone terminal 101 turns off the power of the mobile phone terminal 101 reflexively with the help of embarrassment, but when such a fact occurs several times, when riding on public transportation such as a train, Power will always be turned off, and manner violations will be eliminated.
[0065]
Fifth modified example
[0066]
FIG. 12 shows the contents of call disconnection control at the time of handover in the fifth modified example of the present invention. When the mobile phone terminal 101 (see FIG. 1) starts moving at a high speed during a call, the CPU 102 monitors the timing at which the handover is performed (step S361). If handover is to be performed (Y), it is checked whether or not the mobile phone terminal 101 is performing data communication at that time (step S362). If data communication is not being performed and normal voice communication is being performed (N), the communication is disconnected (step S363).
[0067]
On the other hand, if it is determined in step S362 that the data communication is being performed (Y), the data processing is continued by continuing the handover since there is little inconvenience to the surroundings (return). Of course, if the call is switched to a voice call thereafter, the call will be disconnected at the time of the handover, provided that the vehicle is moving at high speed (step S363).
[0068]
Other deformability
[0069]
The present invention is also capable of various modifications. For example, in the embodiment, the path is switched to the mixer 145 and the tone signal 144 or the warning sound is mixed with the voice sent from the other party. However, such a warning sound is mixed and transmitted to the other party. You may do it. In this case, a mixer may be arranged on the transmission side instead of the mixer 145 on the reception side shown in FIG. 3, and the path may be set so as to mix the output of the tone generator 141 with the mixer.
[0070]
Also, to inform the other party that the mobile phone terminal 101 is moving at high speed, say, "The other party is in an environment where you should observe manners." May be generated, and these may be mixed by a mixer and transmitted. Further, regarding the disconnection control at the time of handover according to the fifth modification of the present invention, the allowable number of times of performing the handover may be determined, and the call may be disconnected when the allowable number is exceeded.
[0071]
【The invention's effect】
As described above, according to the first aspect of the present invention, when a mobile phone is designated as a specific mobile phone terminal, the mobile phone terminal is designed to protect manners instead of reducing the fee.Call cannot be made while moving at a speed higher than the specified speed.On the other hand, for a mobile phone terminal other than the specific mobile phone terminal, it is determined whether or not the mobile phone terminal is moving at a predetermined speed or more, such as a speed when a user gets on a bus or a train. When a call is made when it is determined that the user is moving at a speed higher than the predetermined speed, a warning is output. As a result, the owner of a mobile phone terminal other than the specific mobile phone terminal may not be able to continue the call or the call may be interrupted by the alarm sound, and as a result, it is necessary to keep manners in mind. .
[0072]
According to the second aspect of the present invention, in the mobile phone terminal system according to the first aspect, a warning using voice is output when a call is made during high-speed movement. Must obey manners. Further, when the voice is transmitted to the other party, the other party can cooperate to know the situation and end the call.
[0073]
According to the third aspect of the present invention, the portable telephone terminal system according to the second aspect further includes a mixer for mixing the alarm sound with the call voice. You can make it difficult to hear the call, or you can let the other party know that you are in a situation where you should follow manners.
