DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a configuration example of an incoming call notification device of the present invention. If the terminal station is a mobile phone, call from the other station (base station, relay station) (incoming call)
Then, depending on the communication protocol, the terminal station sends a response signal (hereinafter, an incoming call response signal) to the partner station (base station, relay station).

The incoming call notification device 100 has a specific frequency band (800 MHz, 1.5 GM for a mobile phone).
z, or 1.9 GMz) radio waves are received and detected, and a detection signal is output. Therefore, when an incoming call response signal generated by a mobile phone is detected, a signal output period as shown in FIGS. After the end of tH and the signal output period tH, a signal train having a period until the next signal is detected (hereinafter, a rest period tL) is output.

Output period tH of the incoming call response signal and idle period
The length (time) of tL varies depending on the communication network available to the mobile phone, but since there is a fixed pattern as shown in FIGS. 11 and 12 in the period of the first 2 to 3 pulses, By examining the characteristics and comparing with the period of each signal of the received signal sequence, it is possible to determine whether or not the incoming call response signal is issued from the mobile phone.

Specifically, the incoming call notification device 100 measures the output period tH of the received detection signal of the radio wave in the specific frequency band, or the output period tH and the rest period tL (time counting).
Then, when the measured value satisfies the condition value, a drive signal is sent to the alarm mechanism 5 to operate the alarm mechanism 5, and the measured value does not satisfy the condition value, or in a specific case (described later). ), The drive signal is not sent to the alarm mechanism 5, and the operation of the alarm mechanism 5 is stopped.

In FIG. 1, the receiving unit 1 receives a radio wave in a specific frequency band, performs detection, amplifies the detection output, and outputs it to the control unit 4. Therefore, although not shown, the receiving unit 1 includes an antenna capable of receiving a radio wave in a specific frequency band, a received radio wave a.
It has a detection circuit for detecting a signal to obtain a rectangular signal, and an amplifier for amplifying the output of the detection circuit and outputting it as a signal a.

Further, since the strength of the received electric field is inversely proportional to the distance, the receiving section 1 applies the voltage to the amplifier according to the distance so that the user can select the receiving distance.
Is desirably provided. It is desirable that the electric field strength selection unit 2 be configured so that the resistance value can be selected by switching with a switch and that the resistance value can be switched according to the distance. The clock signal generator 3 generates an operation reference signal (clock signal) for the controller 4. Although not shown, the control unit 4 uses a microcomputer including at least a CPU and a ROM, and outputs the output period tH of the output signal from the reception unit or the output period tH and the rest period measured based on the clock signal. Based on tL, the incoming call of the terminal station is determined and the operation of the alarm mechanism is controlled.

The alarm mechanism 5 is a device such as a vibration motor, a light generating device (for example, a lamp), or a warning sound generating device, which can inform the user of an incoming call to a mobile phone. The external shape of the incoming call alarm 100 is small (for example, length 4 cm × width 3) so that it does not get in the way even if it is stored in a chest pocket.
Since the alarm mechanism 5 accommodated therein is extremely small, it can be driven with a very small amount of electric power. In the embodiment, the alarm signal of the vibration motor or the like is amplified by amplifying the drive signal from the control unit 4. Driving the device. In addition,
It goes without saying that the control unit 4 can be configured to control the alarm mechanism 5 by turning on / off the drive switch (or the power supply switch) of the alarm mechanism by the control signal.

The alarm stop unit 6 is composed of a reset button, a switch and the like, and a user who knows that the mobile phone or the like he / she has received an incoming call by the incoming call alarm 100 performs an alarm operation for a call. It is a mechanism for stopping. The alarm stop unit 6 controls the control unit 4 to the alarm mechanism 5
If it is configured to automatically stop after operating for a predetermined time, it is not necessary to provide it, but for convenience of use,
It is desirable to provide the alarm stop unit 6 so that the user can arbitrarily stop the operation of the alarm mechanism.

2 and 3 are block diagrams showing the structure of programs stored in the ROM of the control unit 4 and sequentially executed by the CPU. FIG. 2 is for an analog communication type terminal station. 3 is for a terminal station of digital communication system.

In FIG. 2, the CPU measures the period of each signal received from the receiving unit 1 by the time measuring means 41 (the signal output time tH and the time until the next signal is output (hereinafter, the rest period tL)).
To measure. Next, the comparison means 42 outputs the signal output time tH,
Alternatively, it is determined whether the signal output time tH and the signal rest time tL satisfy the conditions for comparison. As a comparison condition, an upper and lower limit value (threshold value) of the length of the signal output time tH and an upper and lower limit value (threshold value) of the length of the signal rest time tL, or a length of a sum of the signal output time tH and the signal rest time tL is used. It is desirable to use upper and lower limit values (threshold values). If the comparison means 42 determines that the condition is satisfied, it is determined that the terminal station such as the mobile phone of the user has received a call, and the control is transferred to the alarm mechanism control means 46. Alarm mechanism control means 46
Controls the operation of the alarm mechanism 5. In this embodiment, a driving signal is output under a predetermined condition to drive the alarm mechanism 5,
The alarm mechanism 5 is controlled by not outputting the drive signal except under a predetermined condition. The malfunction prevention means 47 is provided when the alarm stop unit 6 is operated or when the alarm mechanism control means 4 is operated.
If the control unit 4 immediately returns the control to the time measuring means 41 when the control is transferred from 6, the transmitted radio wave may be determined as the incoming call response signal in some cases. The determination of the incoming response of the signal by 42 is not performed for a predetermined time.

In FIG. 3, the CPU measures the period of each signal received from the receiving unit 1 by the time measuring means 44 (the signal output time tH and the time until the next signal is output (hereinafter, the rest period tL).
To measure. Next, the comparison means 44 outputs the signal output time tH,
Alternatively, it is determined whether the signal output time tH and the signal rest time tL satisfy the conditions for comparison. As a comparison condition, an upper and lower limit value (threshold value) of the length of the signal output time tH and an upper and lower limit value (threshold value) of the length of the signal rest time tL, or a length of a sum of the signal output time tH and the signal rest time tL is used. It is desirable to use upper and lower limit values (threshold values). If the comparison means 44 determines that the conditions are satisfied, the control is transferred to the alarm mechanism control means 46 on the assumption that the terminal station such as the mobile phone of the user has received a call. It should be noted that when the comparison unit 44 determines that the roaming is performed, the roaming processing unit 4 is performed.
Control is transferred to 5. Note that roaming is a method of using another communication network that covers the partner station when trying to communicate with the partner station outside the communication area covered by a communication network. Since a pulse train A ′ composed of three pulses as shown in FIG. 12B appears, roaming can be determined. The alarm mechanism control means 46 and the malfunction prevention means 47 are the same as those in the case of FIG. 2 and the description thereof is omitted (however, in the case of FIG. 3, the malfunction prevention means 47 is controlled when the roaming processing unit 45 transfers control). Also works).

(SW2) 6 is shown. The microcomputer 4 sequentially executes the program shown in FIG. 2 or 3 stored in the ROM to determine the signal a from the receiving unit 1, and in the case of an incoming call, the drive control signal c
Is output. The drive control signal c is amplified by the amplifiers 51 and 52 to drive the vibration motor. When the button switch 6 is pressed, the signal d is input to the microcomputer 4, and when the microcomputer 4 receives the signal c, it does not output the drive signal for a predetermined time, so the vibration motor 5 stops during that time.

FIG. 5 shows an operation example of the time measuring means 41 and the comparing means 42 in FIG.
7 shows an operation example of the alarm mechanism control means 46, and FIG. 8 shows an operation example of the malfunction prevention means 47. Although the vibration motor is used as the alarm mechanism 5 in FIGS. 6 and 7, the vibration motor M is also used when a light generator or a voice warning device is used, except for the duration of operation (stop) time. It is similar to the case.

When the mobile phone of the analog communication system receives a call, as shown in FIG. 11A, a pulse A having an output period of tH1 and a rest period of tL1 and a pulse C after the period tL1.
And when the output period is t as shown in FIG.

In FIG. 11A, the output period tH1 of the pulse A and the rest period tL1 have a fixed time relationship, and FIG.
Since there is a fixed time relationship between the output period tH3 of the pulse A ′ or the output period tH4 of the pulse B ′, the output period tH3 of the pulse A ′ and the rest period tL3, or the output period tH4 of the pulse B ′ and the rest period TL4. The incoming response signal is determined by associating these relationships with condition values.

FIG. 5A shows an operation example of the time measuring means 41 and the comparing means 42 applied in the former case, and FIG. 5B shows the time measuring means 41 and the comparing means 42 applied in the latter case.
Is an operation example of. In FIG. 5A, the control unit 4 performs step S
In step 1, initial settings such as counter value setting are performed, and step S
In step 2, the output periods tH1 and tH2 (time) of a certain output signal and an output signal continuous to the certain output signal are sequentially measured (counted).

In step S3, the output period tH1 is set to the condition value 1
And the idle period tL1 is compared with the condition value 2, and the output period tH
When 1 is within the range of the condition value 1 and the condition value 2, it is determined that the incoming call response signal is output, and the control is shifted to the execution of the alarm mechanism control means 43 of FIG. 6 or 7. Step S3
If the output period tH1 is outside the range of the condition value 1 or tL1 is outside the range of the condition value 2, the process returns to step S2 to measure the output period of the next output signal. Here, step S2 corresponds to the time measuring means 41, and step S3 corresponds to the comparing means 4.
Equivalent to 2. In this embodiment, the condition value 1 is 40 ms.
<TH1 <60 ms, condition value 2 0.4s <tH2 <
It is set to 1.2 s.

In FIG. 5B, the control section 4 executes step S11.
Initial settings such as setting the counter value are performed in step S1.
In 2, the output period of a certain output signal (first signal) and the rest periods tH1 and tL1 (time) are sequentially measured (counted). In step S13, the output period tH1 is set to the condition value 3
When the output period tH1 or tH2 is within the range of the condition value 3, the process proceeds to step S14, and when the output period tH1 is outside the range of the condition value 3, the output period tH1 and the rest period tL1 are compared with the condition value 4. If both the output value tH1 and the rest period tL1 satisfy the condition value 4, the process proceeds to step S14. If the output period tH1 or tL1 does not satisfy the condition value 4 in step S13, the process returns to step S2 to measure the output period of the next output signal. In step S14, the next output signal is used as the first signal for the output period and the rest periods tH1, t
Measure (count) L1 (time). Step S15
Then, the output period tH1 and the rest period tL1 are set to the condition value 5
When the output periods tH1 and tL1 satisfy the condition value 5, it is determined that the incoming call response signal is output, and the control shifts to the execution of the alarm mechanism control means 43 of FIG. 6 or 7. If the output period tH1 or the rest period tL1 does not satisfy the condition value 5 in step S15, the process returns to step S12 to measure the output period of the next output signal. Here, steps S12 and S14 are the time measuring means 41.
Corresponding to steps S11 and S15, the comparing means 42
Is equivalent to In this example, the condition value 3 is set to 96 ms <
tH1 <144 ms and 0.4s <tL1 <1.4
s, condition 4 is 32 ms <tH1 <72 ms and tL1
<180 ms, condition 5 is 40 ms <tH1 <96 ms,
0.4s <tL1 <1.4s.

In FIG. 6, when the control is transferred from FIG. 5A or 5B, driving of the motor M is first started in step 21. Since the motor M is, for example, an eccentric motor and vibrates when driven, the user of the incoming call notification device 100 can detect that there is an incoming call in the mobile phone. Step 22
Then, it is determined whether or not the reset button 6 has been pressed. When the reset button 6 is pressed, the control is transferred to the malfunction prevention means 47 of FIG. Since the signal d is sent to the control unit 4 when the reset button 6 is pressed, the control unit 4 constantly checks whether or not the signal d is sent, and then the reset button 6
It can be determined whether or not has been pressed. In step S23, the operation time of the motor M is counted by the motor operation time counter, and the operation time of the motor M is tM (about 3 in this embodiment).
The motor M is driven until it exceeds the second). When the operating time of the motor M exceeds tM, the driving of the motor M is stopped in step S24. After that, the stopped state of the motor M is continued for 2 seconds in steps S25 and S27, and then the process returns to step 21. In step 26, it is checked whether or not the reset button is pressed (similar to the case of step 22), and if the reset button 6 is pressed, the control is transferred to the malfunction prevention means 47 of FIG. Step S28 checks the entire alarm operation time. That is, when the entire operation time of the motor M and the stop time have passed the predetermined time, the control shifts to the execution of the time measuring means 41 and the comparing means 42 of FIG. In the present embodiment, the maximum alarm operating time is set to (motor operating time 3 seconds + stopping time 2 seconds) × 5 = 30 seconds, but these numerical values may be set appropriately.

In FIG. 7, when the control is transferred from the comparing means shown in FIG. 5A or 5B, the driving of the motor M is first started in step 31. Since the motor M is, for example, an eccentric motor and vibrates when driven, the user of the incoming call notification device 100 can detect that there is an incoming call in the mobile phone. In step 32, it is determined whether or not the reset button 6 has been pressed. When the reset button 6 is pressed, the control is transferred to the malfunction prevention means 47 of FIG. In step S33, the operation time of the motor M is counted by the motor operation time counter, and the operation time of the motor M is tM (about 3 in this embodiment).
The motor M is driven until it exceeds the second). When the operating time of the motor M exceeds tM, the driving of the motor M is stopped in step S34.

When the control is transferred from FIG. 5 (a), when the control is transferred from FIG. 5 (b) for the signal sequence after the first signal (pulse C in FIG. 11 (a)). Counts the number of signals appearing in step S35 for the second signal and thereafter (pulse C ′ in FIG. 11B), and step S36
Compare the count value with Condition 6. If the comparison result satisfies the condition 6, the stopped state of the motor M is continued for 2 seconds in steps S37 and S39, and then the process returns to step 31. In step 36, it is checked whether or not the reset button has been pressed, and if the reset button 6 has been pressed, control is transferred to the malfunction prevention means 47 of FIG. Step S38 checks the entire alarm operating time. That is, when the entire repetition of the operation time and the stop time of the motor M exceeds the maximum alarm operation time, the control shifts to the execution of the time measuring means 41 and the comparing means 42 of FIG. In this embodiment, the maximum alarm operation time = (motor M operation time 3 seconds + stop time 2 seconds)
× 5 (number of repetitions) = 30 seconds, but these times may be set appropriately. If the condition 6 is not satisfied in step S36, the appearance of the signal is further checked a predetermined number of times (four times in this embodiment) in steps S41 and S42, and if the signal still does not appear, it is regarded as no signal, and the condition of FIG. The control is shifted to the execution of the time measuring means 41 and the comparing means 42, and if they appear, the routine proceeds to step S38. In this embodiment, the condition value 6 is the rest period tL = 1 second.

In FIG. 8, when the response to the incoming call is not finished on the mobile phone side even if the alarm operation is finished, the control is performed in step S1 of FIG. 5A or step S11 of FIG. 5B. However, in some cases, the transmitted radio wave may be erroneously determined as the incoming call response signal. Therefore, the return time is delayed so that the comparing means 42 does not perform the incoming call response determination of the signal for a predetermined time. The number of signals appearing in step S51 is counted, and the count value is compared with the condition 6 in step S52. When the comparison result satisfies the condition 6, steps S53 and S54 are steps S51 and S5.
2 is repeated a predetermined number of times (six times in this embodiment), and then FIG.
(A) Step S1 or FIG. 5 (b) Step S1
Return to 1. If the condition 6 is not satisfied in step 52, the process returns to step S51 again.

As described above, according to the incoming call notification device of the present invention, it is determined whether or not the output signal is the incoming call response signal based on the output period of the output signal from the receiving section, or the output period and the idle period. Since the alarm mechanism operates when the terminal station is called by the partner station, the alarm mechanism does not operate even during transmission as in the conventional case.
Further, since the detection output signal from the receiving section is judged by the control section to control the alarm mechanism, the number of circuits or elements constituting the incoming call notification device can be small, and the apparatus can be downsized.
