Description

  The present invention relates to a wireless communication apparatus and a power supply method, and more particularly to a wireless communication apparatus and a power supply method that reduce power consumption.

Conventionally, as a wireless communication apparatus and a power supply method, there is one described in Patent Document 1. In Patent Document 1, it is detected that the radio wave has moved out of the radio wave reception area, and the power is intermittently turned on by the receiving unit based on the reception status of the radio signal within a certain past time until the shift to the outside of the radio wave reception area is detected. The time interval to supply is controlled.
JP-A-10-51833

  However, in the conventional technology, since the past radio wave reception environment before moving outside the radio wave reception area is good, the power supply interval to the receiving unit is shortened to respond to low power consumption. However, there is a problem that wasteful power is consumed in spite of the low usage frequency.

  In addition, because the past radio wave reception environment is poor, the power supply interval to the receiving unit is lengthened to respond to the quick return of the radio wave reception area. There is a problem that a delay in returning to the reception area occurs. Furthermore, by controlling the time interval for supplying power according to the change in the radio wave reception status before moving out of the radio wave reception area, wasteful power consumption is performed during low usage periods, and during high usage periods, There is a problem that the return within the radio wave reception range is delayed.

  The present invention has been made in view of such a point, and when the wireless communication device has moved out of the radio wave reception area, the reception is performed according to the frequency of use of the radio communication apparatus by the user in the time zone outside the radio wave reception area. It is an object of the present invention to provide a wireless communication apparatus and a power supply method that can satisfy a demand for a reduction in power consumption and a quickness to return to a radio wave reception area by controlling a time interval for supplying power to a unit.

  The wireless communication device of the present invention includes a receiving unit that receives a radio signal, an out-of-range determining unit that determines whether the radio signal is out of a radio wave reception area, and an outgoing / incoming frequency indicating the frequency of outgoing and incoming radio signals. When the outgoing / incoming frequency storage means for storing for each arbitrary time zone, the time management means for managing the current time, and the out-of-range determination means determine that the radio wave is out of the radio wave reception range, the current time is included in the time zone. Control means for controlling the time interval for supplying power to the receiving means based on the corresponding outgoing / incoming frequency, and power supply means for supplying power to the receiving means using the time interval controlled by the control means. The structure to be provided is taken.

  According to the present invention, when the wireless communication device is moved out of the radio wave reception area, the time interval for supplying power to the receiving unit in the time zone outside the radio wave reception area according to the frequency of use of the wireless communication apparatus by the user. By controlling the power consumption, it is possible to satisfy the demand for rapid power consumption reduction and return to the radio wave reception area.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is an example of a block diagram showing a schematic configuration of a radio communication apparatus according to Embodiment 1 of the present invention. Here, a mobile phone 100 will be described as an example of a wireless communication device.

  The cellular phone 100 mainly includes a wireless unit 101, a time management unit 102, a control unit 103, a power supply unit 104, an incoming / outgoing frequency storage unit 105, and an antenna 109. Radio unit 101 includes a reception unit 106, a transmission unit 107, and an out-of-service determination unit 108.

  The wireless unit 101 transmits and receives wireless signals via the antenna 109. The receiving unit 106 receives a radio signal, and the transmitting unit 107 transmits a radio signal. The out-of-service determining unit 108 determines whether the mobile phone 100 is within a radio wave reception area in which a radio signal can be received or out of a radio wave reception area in which a radio signal cannot be received. Generally, whether the radio wave reception area is out of the service area or not is determined when the synchronization signal is not synchronized.

  The time management unit 102 manages and outputs time elements. The time element includes the current time. In addition to the current time, the time element may include only the day of the week when it includes the day of the week.

  The outgoing / incoming frequency storage unit 105 is a storage area that digitizes the usage frequency (number of incoming / outgoing calls) of the mobile phone 100 in a predetermined time zone and stores it as an outgoing / incoming frequency in association with each predetermined time zone.

  The power supply unit 104 supplies power to the reception unit 106 and the transmission unit 107.

  When the out-of-service determination unit 108 determines that the out-of-service determination unit 108 is out of the radio wave reception service area, the control unit 103 causes the power supply unit 104 to send to the reception unit 106 based on the current time and the outgoing / incoming frequency stored in the outgoing / incoming frequency storage unit 105. Control the power supply. A specific operation example of power control will be described later.

  Next, the operation of the wireless communication apparatus having the above configuration will be described with reference to FIGS. 2 and 3 by taking the mobile phone 100 as an example.

  FIG. 2 shows an example of an operational flowchart of power control when the radio wave is moved out of the radio wave reception area, and FIG. 3 is a diagram showing a configuration example of the outgoing / incoming frequency table.

  The outgoing / incoming frequency table is an example of a table stored in the outgoing / incoming frequency storage unit 105. The outgoing / incoming frequency table shown in FIG. 3 divides the incoming / outgoing frequency (Frequency) into three types of usage frequencies of 1, 2 and 3, and shows outgoing / incoming frequencies corresponding to the time zone from 0 o'clock to 24 o'clock. Yes.

First, when the out-of-range determination unit 108 determines that the radio wave has not been received, the control unit 103 reads (acquires) the current time from the time management unit 102 (S101). Subsequently, the control unit 103 searches the outgoing / incoming frequency table using the read current time, and reads out the outgoing / incoming frequency in the time zone corresponding to the current time (the time zone including the current time) from the incoming / outgoing frequency table ( S102). The control unit 103 sets a time interval (power supply time interval) that the power supply unit 104 supplies to the reception unit 106 using the read outgoing / incoming frequency. In this embodiment, when sending and receiving frequency is 1 (S103), sets the time interval _{T 1} (S104). If incoming and outgoing frequency is 2 instead 1 (S105), it sets the time interval _{T 2} (S106). If incoming and outgoing frequency is neither 2 Any 1, it sets the time interval _{T 3} (S107). About incoming and outgoing frequency is high incoming and outgoing frequency 3, it is set to a shorter time interval T ₃ and time interval. The power supply unit 104 controls the power supplied to the receiving unit 106 at set time intervals.

Here, three types of patterns are shown in which the outgoing / incoming frequency is 1, 2, 3 and the time intervals are T ₁ , T ₂ , T ₃ (T ₁ <T ₂ <T _{3 in} this embodiment). However, the present invention is not limited to this, and finer types of outgoing / incoming frequencies and time intervals may be set.

  In the first embodiment, the case in which the outgoing / incoming frequency is associated with each time zone has been described as an example. However, the present invention is not limited to the outgoing / incoming frequency corresponding to each day time zone. The outgoing / incoming frequency storage unit 105 may be configured for each day of the week, and the outgoing / incoming frequency may be associated with the day of the week and the current time. Furthermore, regardless of the time zone of the day, it may be a case where the outgoing / incoming frequency is set for each day of the week.

  As described above, according to the present embodiment, the power supply interval to the receiving unit 106 when the user is out of the radio wave reception area is controlled based on the user's outgoing / incoming frequency when moving out of the radio wave reception area. By increasing the supply interval, power consumption can be further reduced, and by reducing the power supply interval when the usage frequency is high, the radio wave reception area can be quickly returned.

(Embodiment 2)
FIG. 4 shows an example of a schematic configuration block diagram of the mobile phone 200 according to Embodiment 2 of the present invention. Also in this embodiment, description will be made using a mobile phone 200 as an example of a wireless communication device. The present embodiment is different from the first embodiment in that the use frequency of the user is registered in the outgoing / incoming frequency storage unit 105 of the portable wireless device from the outgoing / incoming history of the wireless unit 101.

  In addition to the mobile phone 100 of FIG. 1, the mobile phone 200 includes an outgoing / incoming history storage unit 201, an incoming / outgoing counter 203, and an outgoing / incoming frequency determination unit 204. In the mobile phone 200 of FIG. 4, a radio signal transmitted / received via the antenna 109 is input to the time management unit 202. Furthermore, the time management unit 202 has a function different from that of the time management unit 102 of the mobile phone 100 of the first embodiment.

  The outgoing / incoming history storage unit 201 is a storage area for storing the number of outgoing / incoming calls (number of outgoing / incoming calls) counted by the outgoing / incoming call counter 203.

  The outgoing / incoming counter 203 is a counter that counts the number of outgoing / incoming calls. The outgoing / incoming counter 203 counts up based on an instruction from the time management unit 202. Further, the time management unit 202 detects that the mobile phone 200 has made or received a call by inputting a radio signal.

  The outgoing / incoming frequency determination unit 204 determines the number of outgoing / incoming calls using a predetermined threshold and associates it with the outgoing / incoming frequency. Here, as in the first embodiment, the outgoing / incoming frequency will be described using three numerical values 1, 2, and 3.

  The time management unit 202 has the following functions in addition to the functions described in the first embodiment. The time management unit 202 detects that the mobile phone 200 has made / received a call by the input of the radio signal, and notifies the call / call counter 203 of the call. Further, the time management unit 202 manages the timing for starting the outgoing / incoming frequency determination unit 204. Specifically, the time management unit 202 holds a scheduler function for detecting a time zone break, and activates the outgoing / incoming frequency determination unit 204 when a time zone break is detected.

  4 having the same reference numerals as those in FIG. 1 have the same names and have the same functions, and thus description thereof is omitted.

  Next, the operation of mobile phone 200 according to the present embodiment will be described with reference to FIGS.

FIG. 5 shows an example of an operation flowchart of the outgoing / incoming history storage according to the present embodiment, FIG. 6 shows an example of an operation flowchart for determining the outgoing / incoming frequency from the number of outgoing / incoming calls per time, and FIG. It is a figure which shows an example of the outgoing / incoming frequency table. The outgoing / incoming frequency table shown in FIG. 7 divides 0:00 to 24:00 into hourly time zones, and stores the outgoing / incoming frequency and outgoing / incoming frequency in each time zone. For example, the time zone 10 indicates a time zone from 10:00 to 1 hour.
Hereinafter, operations different from those of the first embodiment will be described.

First, the operation of storing / receiving call history will be described with reference to FIG.
The operation of storing the outgoing / incoming call history is in a waiting state until the incoming / outgoing call is detected, and starts when the incoming / outgoing call is detected. Detection of outgoing / incoming calls is detected by a signal input to the time management unit 202. When an incoming signal to the receiving unit 106 or a transmission signal to the transmitting unit 107 is input (S201), the time management unit 202 reads the current time (S202), and the outgoing / incoming counter 203 counts the number of outgoing / incoming calls per hour. Is counted (S203), and the counted number of outgoing / incoming calls is stored in the outgoing / incoming history storage unit 201 (S204). Next, until the incoming / outgoing call is detected, the operation of the incoming / outgoing call history storage is in a waiting state.

Next, the operation for determining the outgoing / incoming frequency will be described with reference to FIGS.
When detecting that the time interval stored in the outgoing / incoming frequency table has elapsed, the time management unit 202 causes the outgoing / incoming frequency determination unit 204 to determine the outgoing / incoming frequency. At this time, the time management unit 202 notifies the outgoing / incoming frequency determination unit 204 of the time zone for performing the determination. Sending and receiving frequency determination unit 204 reads out the outgoing call number stored in the call history storage section 201 (S211), if the incoming and outgoing number of times per read time zone is greater than N ₁ (S212), sending and receiving frequency 1 is set (S213). Further, if sending and receiving number of times per time period is greater than _{N 2} at _{N 1} or less (S214), it sets the incoming and outgoing frequency 2 (S215). When the number of outgoing / incoming calls per time slot is N ₂ or less, the outgoing / incoming frequency 3 is set (S216).

  The outgoing / incoming frequency determination unit 204 associates the time zone notified from the time management unit 202 with the determined usage frequency and registers it in the outgoing / incoming frequency table. Specifically, the outgoing / incoming frequency determined by the outgoing / incoming frequency determination unit 204 is stored as in the outgoing / incoming frequency table of FIG. When shifting outside the radio wave reception area, the control unit 103 controls the power supply time interval as shown in the flowchart of FIG. 2 based on the outgoing / incoming frequency stored in the outgoing / incoming frequency table.

  Here, as an example, an example is shown in which there is one outgoing / incoming frequency table for determining outgoing / incoming frequency based on the number of outgoing / incoming calls per fixed time. However, the present invention is not limited to this, and the day of the week is not limited to this. By preparing several patterns such as every time, the outgoing / incoming frequency may be registered according to several life cycles.

  The outgoing / incoming history storage unit 201 holds at least the number of outgoing / incoming calls in one time zone. Further, the outgoing / incoming history storage unit 201 may be configured to hold the number of outgoing / incoming calls and the time zone, or may be configured to hold the time zone and the outgoing / incoming frequency in association with each time zone. Good.

  In this embodiment, the case where the time management unit 202 has a scheduler function has been described. However, a timer may be provided separately from the time management unit 202, and the timer may realize the scheduler function. .

  As described above, according to the present embodiment, the number of outgoing / incoming calls for each time zone is determined by using the outgoing / incoming frequency using the outgoing / incoming history such as the number of outgoing / incoming calls for each time zone (or every day of the week). can do. Controls the power supply interval to the receiving unit when the wireless communication device moves out of the radio wave reception area from the user's outgoing / incoming frequency and time zone according to the created outgoing / incoming frequency table, and sets the power supply interval when the usage frequency is low By increasing the power consumption, it is possible to further reduce power consumption, and to quickly return to the radio wave reception area by reducing the power supply interval when the usage frequency is high. Furthermore, fine control of power supply can be performed by creating the outgoing / incoming frequency table using time elements (predetermined time, day of week, etc.) according to the life cycle.

(Embodiment 3)
FIG. 8 shows an example of a schematic configuration block diagram of mobile phone 300 according to Embodiment 3 of the present invention.

  Also in this embodiment, description will be made using a mobile phone 300 as an example of a wireless communication device. The present embodiment is different from the first or second embodiment in that the registration from the user is accepted when the outgoing / incoming frequency is registered in the outgoing / incoming frequency storage unit of the wireless communication apparatus.

  FIG. 8 shows an example of a schematic configuration block diagram of mobile phone 300 according to the present embodiment. The mobile phone 300 includes an input unit 301 and an outgoing / incoming frequency storage unit 302 in addition to the mobile phone 100 of FIG.

  The input unit 301 receives an input of the value of the outgoing / incoming frequency from the user, and stores the input outgoing / incoming frequency in the outgoing / incoming frequency table.

  The outgoing / incoming frequency storage unit 302 stores the outgoing / incoming frequency received by the input unit 301 in association with the time zone in the outgoing / incoming frequency storage unit 105.

Next, the operation of the mobile phone 300 will be described with reference to FIG.
FIG. 9 shows an example of an operational flowchart of the outgoing / incoming frequency storage according to the present embodiment. Only the flow different from the first embodiment will be described below.

  The input unit 301 provides a screen for the user to input the incoming / outgoing frequency, and waits for the user to start input via an input device (eg, keyboard, mouse, etc.) (S301).

  The screen provided by the input unit 301 includes an area for inputting a time zone for specifying a certain time interval and an area for inputting a usage frequency. The time zone and the usage frequency may be in a form in which a plurality of options are displayed and one option is selected for each. Here, the frequency of use will be described as an example where the user selects one of the other three frequently used or occasionally used.

  When the input unit 301 detects that the user has input (S301), the input unit 301 acquires time zone and usage frequency data input by the user (S302).

  Next, the outgoing / incoming frequency storage unit 302 determines the outgoing / incoming frequency based on the usage frequency at regular time intervals based on the time zone and usage frequency data acquired by the input unit 301, and the determined outgoing / incoming frequency The frequency is stored in the outgoing / incoming frequency table included in the outgoing / incoming frequency storage unit 105 (S303 to S307).

  In the case of a frequently used time zone (S303), the outgoing / incoming frequency storage unit 302 sets the outgoing / incoming frequency 3 (S304). If it is not a frequently used time zone but an occasional time zone (S305), the call frequency is set to 2 (S306). If it is not a frequently used time zone or a occasionally used time zone, the call frequency is set to 1 (S307). When the mobile phone 300 moves out of the radio wave reception area, the power supply time interval to the control unit 103 is controlled as shown in the flowchart of FIG. 2 from the outgoing / incoming frequency table in which data is stored by the outgoing / incoming frequency storage unit 302. To do.

  In addition, although the example which registers a use time zone and frequency was given here, this invention is not restricted to this, You may register use frequency according to lifestyle, such as a trip, a school, and work. .

  As described above, according to the present embodiment, the user mainly designates the time zone to be used, and controls the power supply time interval according to the outgoing / incoming frequency registered based on the designation from the user. However, if the frequency of use is low, power consumption in the registered time zone can be further reduced, and if the frequency of use is high, return within the radio wave reception area of the registered time zone can be performed quickly.

(Embodiment 4)
FIG. 10 shows an example of a schematic block diagram of a radio communication apparatus according to Embodiment 4 of the present invention. Also in this embodiment, a mobile phone 400 will be described as an example of a wireless communication device. The present embodiment is different from the first embodiment in that the time interval for supplying power to the power supply unit is controlled using the location information of the mobile phone 400 and the outgoing / incoming frequency stored in the outgoing / incoming frequency table. .

  The mobile phone 400 includes a position information acquisition unit 402 and a timer 403 in addition to the mobile phone 100 of FIG. 1, and the control unit 401 has a function different from that of the control unit 103 of the mobile phone 100.

  The control unit 401 performs power supply control using the position information and the outgoing / incoming frequency table. Other functions are the same as those of the control unit 103 of the mobile phone 100.

  The position information acquisition unit 402 acquires position information from a device that measures position information, classifies the acquired position information into predetermined types, sets a current location, and stores the set current location. Here, a case where the present location is classified into three types, that is, an urban area, a suburb, and the like will be described. The three types are classified from position information (latitude and longitude). The position information acquisition unit 402 holds boundary information of the three types of corresponding position information, and classifies the current location based on the boundary information. The boundary information indicates the position that is the boundary between the urban area, the suburbs, and others. In FIG. 10, a GPS (Global Positioning System) 1000 is shown as an example of a device that measures position information.

  The timer 403 measures a certain time, and instructs the position information acquisition unit 402 to start processing when the certain time has elapsed.

  10 that have the same reference numerals as those in FIG. 1 have the same names and similar functions, and therefore description thereof is omitted.

  Next, the operation of mobile phone 400 according to the present embodiment will be described with reference to FIGS.

  FIG. 11 shows an example of an operation flowchart for registering the current location according to the present embodiment, and FIG. 12 shows an example of an operation flowchart of power supply control when the current location is moved out of the radio wave reception area. Hereinafter, operations different from those of the first embodiment will be described.

  First, an operation for registering position information will be described.

  The timer 403 receives a time notification from the time management unit 102 and measures a certain time (S401). When it is determined by the timer 403 that a certain time has passed (S402), the position information acquisition unit 402 is instructed to start processing. The position information acquisition unit 402 acquires position information measured by the GPS 1000 (S403), and classifies the acquired position information using the boundary information (S404 to S409). If the location information is included in the urban area (S404), the current location is set in the urban area (S405). If the location information is included in the suburbs instead of the urban areas (S406), the current location is set to the suburbs (S407). If the location information is not included in the urban area or the suburbs, the current location is set to other (ocean, overseas, etc.) (S408). The position information acquisition unit 402 registers the set current location (S409).

  Next, the operation of power supply control will be described.

When detecting that the control unit 401 has moved out of the radio wave reception area, the control unit 401 determines a power supply time interval for supplying power. Specifically, as in the first embodiment, any one of the time intervals T ₁ , T ₂ , T ₃ is determined based on the outgoing / incoming frequency held in the outgoing / incoming frequency table shown as an example in FIG. S451). The operation at that time follows the power supply control operation flowchart of FIG.

  Next, the current location is read from the position information acquisition unit 402 (S452), and a time interval for supplying power to the receiving unit 106 is set based on the current location and the outgoing / incoming frequency stored in the outgoing / incoming frequency storage unit. Here, the control part 401 demonstrates as an example the case where the coefficient of (alpha) <(beta) <(gamma) is used with respect to a time interval.

  When the present location is an urban area (S453), the power supply time interval to the receiving unit is set to the set time interval × α (S454). When the current location is not an urban area but a suburb (S455), the power supply time interval to the receiving unit is set to the set time interval × β (S456). If the current location is neither urban nor suburb, the power supply time interval to the receiving unit is set to the set time interval × γ (S457). The control unit 401 controls the power supplied to the receiving unit 106 using the set power supply time interval.

  Here, the position information measured by the GPS 1000 is used as means for acquiring the position information. However, the present invention is not limited to this, and the position information may be acquired by other methods.

  As described above, according to the present embodiment, the location where the radio wave reception outlier is higher (where it takes time to recover from outside the radio wave reception range) and the location where the radio wave reception outlier is low (according to the current location information of the user's mobile phone) By controlling the power supply time interval according to the location, such as a user who is out of the radio wave reception area, such as behind a building), the power consumption when the usage frequency is low and the radio wave coverage is high In addition, it is possible to quickly return to the radio wave reception area when the user is in a place where the frequency of use is high and the radio wave reception area is low.

(Embodiment 5)
FIG. 13 shows an example of a schematic configuration block diagram of mobile phone 500 according to Embodiment 5 of the present invention. Also in this embodiment, a mobile phone 500 will be described as an example of a wireless communication device. In this embodiment, the time interval for supplying power to the power supply unit is controlled using the out-of-service counter number indicating the number of times the mobile phone wants to move out of the radio wave reception service area and the outgoing / incoming frequency stored in the outgoing / incoming frequency table. However, this is different from the first embodiment.

  The mobile phone 500 includes an out-of-service counter 502 and a timer 503 in addition to the mobile phone 100 of FIG. 1, and the control unit 501 has a function different from that of the control unit 103 of the mobile phone 100.

  The control unit 501 performs power supply control using the out-of-service transition count counted by the out-of-service counter 502 and the arrival / departure frequency table. Other functions are the same as those of the control unit 103 of the mobile phone 100.

  When the out-of-service counter 502 is notified of the elapse of a predetermined time from the timer 503, the out-of-service counter 502 counts the number of times of out-of-service reception based on the determination by the out-of-service determination unit 108 as to whether it is out of the reception service area.

  The timer 503 measures a certain time and notifies the out-of-service counter 502 when the certain time has elapsed.

  13 that have the same reference numerals as those in FIG. 1 have the same names and similar functions, and therefore description thereof is omitted.

  Next, the operation of mobile phone 500 according to the present embodiment will be described with reference to FIGS.

  FIG. 14 shows an example of an operation flowchart of out-of-service count that counts the number of times of moving out of the radio wave reception range according to the present embodiment, and FIG. 15 shows an example of an operation flowchart for controlling power according to the out-of-service count. Hereinafter, a flow different from that of the first embodiment will be described.

  First, the operation of out-of-service count will be described. The timer 503 receives a time notification from the time management unit 102 and measures a certain time (S501). When it is determined by the timer 503 that the predetermined time has elapsed (S502), the timer 503 instructs the out-of-service counter 502 to start processing. The out-of-service counter 502 acquires radio wave reception information indicating whether it is out of the radio wave reception area or within the radio wave reception area from the out-of-service determination unit 108 (S503). The out-of-service counter 502 determines whether the radio wave reception information is out of the radio wave reception area or not (S504). When it is determined that the radio wave reception is out of service area, the count value held by the service area counter 502 is incremented (S505). If it is determined that it is not out of the radio wave reception area, the out-of-area counter 502 is reset to 0 (zero) (S506).

  Next, the operation for controlling the power supply will be described.

When controlling the power supply interval, the control unit 501 determines a power supply time interval for supplying power. Specifically, as in the first embodiment, any one of the time intervals T ₁ , T ₂ , T ₃ is determined based on the outgoing / incoming frequency held in the outgoing / incoming frequency table shown as an example in FIG. S551). The operation at that time follows the power supply control operation flowchart of FIG.

Next, the control unit 501 reads the counted out-of-service count value (S552), and sets the power supply time interval to the receiving unit based on the out-of-service count value and the outgoing / incoming frequency stored in the outgoing / incoming frequency storage unit. Set. Here, the case where the control unit 501 uses a coefficient of α <β <γ will be described as an example. The out-of-service counter 502 makes a determination using predetermined threshold values (N ₁ , N ₂ ).

When the out-of-service count value is larger than N ₁ (S553), the power supply time interval to the receiving unit is set to the set time interval × α (S554). When the out-of-service count value is N ₁ or less and greater than N ₂ (S555), the power supply time interval to the receiving unit is set to the set time interval × β (S556). When the out-of-service count value is N ₂ or less, the power supply time interval to the receiving unit is set to the set time interval × γ (S557). The control unit 501 controls the set power supply time interval.

Here, when the out-of-service count value is N ₂ or less, the power supply time interval to the receiving unit is set to the set time interval × γ, but the present invention is not limited to this, and the out-of-service count is further limited. When the number is large and / or when the frequency of use is small, the power supply to the receiving unit may be stopped under other conditions.
