Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a communication mobile terminal such as an analog or digital cellular (cell phone), a PHS (simple mobile phone), etc., and particularly when an incoming call is received by the communication mobile terminal, The present invention relates to an incoming call notification system for mobile communication terminals that can notify the user.

[0002]

[Prior art]

 Conventionally, as an incoming call notification device for informing a person of an incoming call to a communication mobile terminal, for example, there is a vibrator for notifying an incoming call by vibrating.To vibrate such a vibrator, the communication mobile terminal receives The frequency detector detects the radio waves of 900 MHz band transmitted to the station to activate the vibrator. However, in such a method using a vibrator, the frequency detection unit of the vibrator detects a radio wave other than that of the mobile communication terminal, or the vibrator vibrates when an incoming call to another mobile communication terminal is detected. It may cause the vibrator to malfunction.

For this reason, a signal dedicated to vibrator control is transmitted from the mobile communication terminal to the vibrator, that is, an ID signal that enables the vibrator side to determine the identity of the mobile communication terminal is transmitted, and this ID signal is stored in the memory of the vibrator. The applicant has proposed a system in which the vibrator is made to vibrate only when it matches the signal stored in the memory.

However, in this system, when the portable terminal for communication uses a weak radio wave as a radio wave dedicated to the vibrator control, the vibrator constantly monitors the weak radio wave in order to detect the ID signal. A highly sensitive ID data detection circuit is required. Therefore, there is a problem that power consumption is increased and battery life is shortened.

In order to solve such a problem, the fact that a mobile terminal for communication transmits a radio wave having a frequency of 900 MHz to the base station when an incoming call from the base station is large is used to make the vibrator use the 900 MHz band. It is possible to reduce the power consumption by providing a function for detecting the frequency and operating the high-sensitivity ID data detection circuit only when the vibrator detects the frequency in the 900 MHz band.

[0006]

[Problems to be solved by the device]

 However, if the sensitivity for detecting the frequency of 900 MHz band is increased, the power consumption is also increased. Therefore, if the sensitivity is decreased, it may depend on the directivity of the mobile terminal for communication that transmits the radio wave of the frequency of 900 MHz band to the base station. Alternatively, depending on the surroundings of the communication mobile terminal, if there is an obstacle such as a bag between the communication mobile terminal and the vibrator, the frequency in the 900 MHz band may not be detected. For this reason, the high-sensitivity ID data detection circuit cannot operate even if an incoming call is actually received, and therefore the weak radio wave dedicated to the vibrator control from the mobile communication terminal cannot be detected. Therefore, even if the mobile communication terminal receives an incoming call, the vibrator cannot be vibrated, and it may not be possible to notify a person of the incoming call.

Therefore, the present invention can reduce power consumption due to the constant operation of the high-sensitivity ID data detection circuit, and can improve the function of notifying a person when there is an incoming call. The challenge is to provide an incoming call notification system.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is designed to transmit an ID signal from the above-mentioned mobile communication terminal to the data receiving section of the incoming notification device when the mobile communication terminal receives an incoming call, thereby transmitting the incoming call. In an incoming call notification system for a mobile communication terminal, wherein the notification device performs an incoming call notification operation after detecting the ID signal, the incoming call notification device transmits and receives radio waves between the communication mobile terminal and a base station. A frequency detection section for receiving the radio wave from the communication portable terminal, an ID data detection section for receiving a radio wave from the communication mobile terminal and detecting the ID signal, and an ID data from the ID data detection section. Is compared with the data stored in the memory in advance and the control unit for controlling the incoming call notification device according to the result and the ID data detection unit are changed from the low power consumption state to the high sensitivity state at regular intervals. When the frequency detection unit detects the frequency or when the transition timer outputs a transition signal, the ID data detection unit is provided with high sensitivity from a low power consumption state. It is characterized by being configured to shift to a state.

According to the incoming call notification system for the mobile communication terminal having such a configuration, when the frequency detection unit of the incoming call notification device detects the frequency of the radio wave transmitted and received between the mobile communication terminal and the base station. The control unit shifts the ID data detection unit from the low power consumption state to the high sensitivity state so that the ID signal from the communication portable terminal can be detected. In this way, when the operation of the ID data detection unit is started in the high sensitivity state, the ID data detection unit does not need to always operate with high sensitivity. Power consumption can be reduced compared to.

If the frequency detection unit of the incoming call notification device cannot detect the frequency of the transmitted and received radio waves for some reason, the transition timer outputs a signal at regular intervals, so that the control unit receives the ID data. The detection unit is shifted from the low power consumption state to the high sensitivity state, and if there is an incoming call at the communication portable terminal at that time, the ID radio wave from the communication portable terminal is detected.

In this way, when the operation of the ID data detection unit is started in the high sensitivity state, the ID data detection unit is set to a low level in a time zone other than the time when the high sensitivity state is set in every fixed cycle. It is possible to enter the power consumption state, and since it is not necessary to always operate with high sensitivity, power consumption can be reduced. Even if the frequency detection unit cannot detect the frequency of the transmitted and received radio waves for some reason, the mobile communication terminal can be notified of an incoming call, which improves the function of the incoming call notification device. be able to.

[0012]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 are diagrams showing an incoming call notification system for a portable terminal for communication according to a first embodiment of the present invention.

A mobile phone (communications mobile terminal) 10 shown in FIG. 1 has an antenna 12 for performing radio communication with a base station (not shown) by radio waves, and the antenna 12 is connected to the antenna 12. A main body circuit 14 that demodulates a signal transmitted from a base station via the main body circuit 14; and a control unit 16 that is connected to the main body circuit 14 and that controls each component of the mobile phone 10 to operate the mobile phone 10 with a communication function. have.

The operation up to this point is similar to that of an ordinary mobile phone, but the mobile phone 10 of the present embodiment further drives a small vibrator 25 (see FIG. 2) as an incoming call notification device described later by radio waves. Has a remote control function. That is, a vibrator data transmission unit 18 is connected to the control unit 16, and the data transmission unit 18 is controlled by the control unit 16 to transmit a high frequency amplified signal from the remote control antenna 20 to the small vibrator 25. Send by. The signal to be transmitted is an ID signal, that is, a signal unique to the mobile phone 10, and is a signal indicating the identity of the mobile phone 10.

The small vibrator 25 shown in FIG. 2 receives the radio wave from the remote control antenna 20 of the mobile phone 10 by the remote control antenna 27, amplifies the transmitted signal by the high frequency amplification circuit 29 at a high frequency, and the ID data detection unit. An ID signal is detected by 31 and the data is input to the control unit 30. The ID data detection unit 31 can be operated with high sensitivity by being turned on by the power supply 39 when the switch 37 is turned on by the control unit 30.

The control unit 30 determines whether the ID data from the ID data detection unit 31 is the same as the data stored in the memory 35, and when it is determined that the ID data is the same, the vibration operation of the small vibrator 25 is driven. The motor 33, which is the source, is rotated and activated by the operation of the motor drive circuit 36.

The small vibrator 25 includes an antenna 26 for receiving radio waves having a frequency of 900 MHz transmitted from the antenna 12 of the mobile phone 10 to the base station, and a frequency for detecting and outputting the frequency of the 900 MHz band. A detection unit 28 is provided. Further, the small vibrator 25 has a timer (transition timer) 32 that is activated by a timer activation signal from the control unit 30 and outputs a switch activation signal (transition signal) after counting the time corresponding to a certain period. . The switch activation signal output from the timer 32 is input to the other terminal of the OR circuit 34 whose detection output of the frequency detection unit 28 is input to one terminal, and the ON output of the OR circuit 34 is input to the control unit 30. It is designed to be input to. When the ON output of the OR circuit 34 is input, the control unit 30 controls the switch 37 so as to be conductive.

In the mobile phone 10 and the small vibrator 25 configured as described above, when the mobile phone 10 determines that there is an incoming call by the radio wave from the base station, the mobile phone 10 sends the small vibrator 25 by the radio wave. It sends a signal for ID to notify that there is an incoming call. Then, the small vibrator 25 determines whether the signal for the ID is the same as the signal of the memory 35. When the same is determined, the motor 33 is rotated to vibrate the entire small vibrator 25, and the mobile phone 10 receives an incoming call. You can let people know that. Therefore, even if the mobile phone 10 is put in or placed in a bag or other place away from the human body, as long as the small vibrator 25 is in contact with the skin of the body, an incoming call to the mobile phone 10 can be made. You can always inform people.

In performing such a basic operation, in order for the small vibrator 25 to vibrate, one of the two conditions is alternatively required. One of them is that the frequency detection unit 28 detects a frequency in the 900 MHz band, so that the ID data detection unit 31 shifts from a low power consumption state to a detection operation state with high sensitivity (first start). Condition), the other is that the ID data detection unit 31 shifts from a low power consumption state to a state in which a detection operation can be performed with high sensitivity, based on a switch activation signal from the timer 32 at regular intervals. (Second start condition).

First, the first start condition will be described with reference to the left half of FIG. When an incoming call is received by the mobile phone 10 from a base station, the mobile phone 10 transmits a radio wave having a frequency of 900 MHz band to the base station in communication with the base station ((a) in FIG. 3). At this time, the mobile phone 10 simultaneously sends an ID radio wave to the small vibrator 25 from the remote control antenna 20 ((b) of FIG. 3).

At this time, when the radio wave transmitted from the mobile phone 10 to the base station is received by the antenna 26 of the small vibrator 25, the frequency detection unit 28 detects the frequency of 900 MHz band ((c) of FIG. 3). ) Output a signal to the OR circuit 34. As a result, the OR circuit 34 outputs an ON signal to the control unit 30, and the control unit 30 outputs a signal to the switch 37 to make it conductive, whereby the power source 39 supplies power to the ID data detecting unit 31. Then, the ID data detection unit 31, which has been in the low power consumption state (sleep state) up to then, has high sensitivity, and the radio wave from the mobile phone 10 received by the remote control antenna 27 is high-frequency amplified by the high-frequency amplification circuit 29, and then the ID data The detection unit 31 detects the ID signal ((d) in FIG. 3).

The ID data detected by the ID data detection unit 31 is input to the control unit 30 as described above and compared with the data stored in the memory 35 to determine whether or not they are the same. ((F) in FIG. 3). When it is determined that they are the same, the control unit 30 causes the motor 33 to rotate via the motor drive circuit 36 ((g) in FIG. 3) to vibrate the entire small vibrator 25. Therefore, since the ID data detection unit 31 does not need to operate with high sensitivity at all times, it is possible to reduce power consumption as compared with the case where it operates with high sensitivity at all times.

Next, the second start condition will be described with reference to the right half of FIG. Even if a radio wave having a frequency in the 900 MHz band is transmitted from the mobile phone 10 due to an incoming call to the mobile phone 10 ((a) of FIG. 3), if the frequency detection unit 28 of the small vibrator 25 has low sensitivity, Depending on the directivity of the radio wave transmitted to the base station, or depending on the surroundings of the mobile phone 10, if there is an obstacle such as a bag between the mobile communication terminal and the vibrator, the frequency of 900 MHz band May not be able to detect the radio wave. In such a case, the frequency detection unit 28 cannot detect the radio wave of the frequency of 900 MHz band received by the antenna 26 ((c) in FIG. 3).

However, even in such a case, the ID radio wave is transmitted from the remote control antenna 20 of the mobile phone 10 ((b) of FIG. 3), and the switch activation signal is output from the timer 32 at regular intervals. Is output ((e) in FIG. 3) and is input to the OR circuit 34. The ON output from the OR circuit 34 is input to the control unit 30, the switch 37 becomes conductive under the control of the control unit 30, and the power from the power supply 39 causes the ID data detection unit 31 in the low power consumption state to It shifts to a state where it can operate in a high sensitivity state.

Therefore, the ID data detection unit 31 can detect the ID signal received by the remote control antenna 27 through the high frequency amplifier circuit 29 ((d) of FIG. 3), and the mobile phone 10 at that time. If the ID signal is not received from the mobile phone 10 (the mobile phone 10 has no incoming call), the original low power consumption state is restored.

After a lapse of a certain period of time, the ID data detection unit 31 becomes highly sensitive again based on the switch activation signal from the timer 32, and if the ID signal comes from the mobile phone 10 at that time, it is detected. ((D) of FIG. 3). When the control unit 30 determines that the ID data is the same as the data in the memory 35, the motor 33 is rotated.

Therefore, the ID data detection unit 31 does not need to operate with high sensitivity at all times, and power consumption can be reduced. Even if the frequency detection unit 28 cannot detect the frequency of the radio wave in the 900 MHz band for some reason, the mobile phone 10 can be notified of the incoming call. Therefore, the function of the small vibrator 25 is improved. Can be made.

In the above embodiment, the antenna 26 and the frequency detection unit 28 are provided to detect the radio wave of the frequency of 900 MHz band. However, these are not necessarily provided, but the timer 32 does not necessarily provide the ID and the frequency detection unit 28 at regular intervals. By moving the data detection unit 31 to the high sensitivity state, it is possible to reduce the power consumption during the time period of the low power consumption state.

Further, although the above embodiment has been described by taking the mobile phone (cellular) as an example, the present invention can be applied to other communication mobile terminals such as PHS.

Further, in the above-described embodiment, the case where the small vibrator 25 which notifies the incoming call notification to the incoming call by vibration is used, but the incoming call notification device which notifies the incoming call by voice like an alarm is used. Good.

[Effect of the invention]

 As described above, according to the present invention, when the frequency detection unit of the incoming call notification device detects the frequency of the radio wave transmitted and received between the mobile communication terminal and the base station, the control unit causes the ID data detection unit to operate. By shifting from the low power consumption state to the high sensitivity state, the ID signal from the communication mobile terminal can be detected. In this way, when the operation of the ID data detection unit is started in the high sensitivity state, the ID data detection unit does not need to always operate with high sensitivity. Power consumption can be reduced compared to.

If the frequency detection unit of the incoming call notification device cannot detect the frequency of the transmitted / received radio wave for some reason, the transition timer outputs a signal at regular intervals, so that the control unit receives the ID data. The detection unit is shifted from the low power consumption state to the high sensitivity state, and if there is an incoming call at the communication portable terminal at that time, the ID radio wave from the communication portable terminal is detected.

In this way, when the operation of the ID data detection unit is started in the high sensitivity state, the ID data detection unit is set to a low level in a time zone other than when it is changed to the high sensitivity state at regular intervals. It is possible to enter the power consumption state, and since it is not necessary to always operate with high sensitivity, power consumption can be reduced. Even if the frequency detection unit cannot detect the frequency of the transmitted and received radio waves for some reason, the mobile communication terminal can be notified of an incoming call, which improves the function of the incoming call notification device. be able to.

Further, even in the case where the antenna 26, the frequency detection unit 28, and the OR circuit 34 provided in the above-described embodiment are not provided, the ID data detection unit 31 does not always have to be highly sensitive. Since it is completed, the power consumption of the small vibrator 25 can be reduced.
