DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-way communication system in which a base station radio equipment connected to a wired telecommunication network transmits a calling signal or various messages mainly by radio waves in the 280 MHz band to call a called party. The present invention relates to a pager terminal device and a pager system for performing communication of the same.

[0002]

2. Description of the Related Art A conventional pager terminal device always receives a call signal and various messages from a base station radio equipment and informs the user of the call signals and various messages. Must be kept.
For this reason, if the power is turned on all day, the power consumption becomes large. For the purpose of reducing the power consumption, a function called an intermittent reception method is adopted, and the 1.5 V dry battery 1 is used.
There is known a book designed to operate continuously for about one to two months. Here, the intermittent reception method is a method in which a main power supply which is a power supply for a radio reception unit for performing a reception operation and a control unit for performing a call process is turned on and off at a constant interval, for example, for 30 seconds. The main power supply is turned on and off at a timing of a pulse of 1 second at intervals of. In this case, the power consumption is reduced to about 1/30 as compared with the case where the intermittent reception method is not used.

[0003]

In general, a user who uses a pager terminal device is troublesome in turning on and off the main power supply even at night or during business breaks. In many cases, they carry the phone in the ON state. Therefore, there is a problem that power is wasted and the duration of the dry battery is reduced.

[0004]

Therefore, a pager terminal device according to the present invention comprises a timer unit for setting a time at which the main power is turned on and off, and a main power switch when the main power is turned off by the timer unit. Separately, a main power supply is turned off, and a main power supply is turned on separately from a main power supply switch when a main power supply ON time is provided.When the main power supply is turned off, the CPU unit is also provided for the timer unit and the CPU unit. It turned on electricity. In addition, when the main power is turned off by the timer unit when the main power switch is turned on, it is preferable to turn off the power to the clock oscillation unit that oscillates the clock for performing the intermittent reception. Further, the pager terminal device is provided with a timer unit for setting a set time,
During the set time, the radio receiving unit and the control unit are energized, the operation of the notification unit is stopped, and the call message is received. The call message is stored in the storage unit so that the notification operation is not performed. Good. In addition, it is preferable to provide an input unit for the time set in the timer unit.

On the other hand, in the pager system which operates the pager terminal, a setter who sets the time in the timer section transmits the set time to the base station through the telephone network, and transmits the set time from the base station to the pager terminal. By doing so, the time was set in the timer section of the pager terminal device. In this case, the setter may be either a callee holding the pager terminal device or a caller calling the callee holding the pager terminal device.

Further, when a setter who sets the time in the timer unit transmits the set time to the base station through the telephone network, a storage unit for storing the set time is provided in the base station.
Recognizing the set time stored in the storage unit, if a call message is transmitted through the telephone network during a time period when the main power of the pager terminal device is turned off, the fact is stored in the call message storage unit. Then, it is preferable to transmit the call message stored in the call message storage unit to the pager terminal device when the time period when the main power is turned on is reached.

It is for receiving a radio wave of a band. Reference numeral 2 denotes a radio receiving unit for performing frequency conversion and demodulation processing on the radio wave received by the antenna 1 and outputting reproduced data. A control unit 3 controls the operation of the entire pager terminal device, and includes a logic circuit.

Reference numeral 4 denotes a CPU unit for controlling the operation of the pager terminal device in the same manner as the control unit 3. The CPU unit is always supplied with power. 12, the time to be measured is recognized, and the main power of the pager terminal device is switched on and off. Here, the main power supply is the wireless receiving unit 2
And a power supply for switching the operation of the control unit 3,
When the main power supply is turned on, it functions as a pager terminal device so that radio waves from a base station (not shown) can be received, and when the main power supply is off, the radio waves cannot be received. Note that the main power supply is switched as described above separately from the main power switch (not shown) for the user to switch on and off. Therefore, even when the main power switch (not shown) is in the on state, the main power supply is switched as described above. First, the CPU unit 4 can turn off the main power supply. Further, when a main power switch (not shown) is in an off state, it is preferable that the on / off of the main power by the CPU unit 4 is changed according to the operation state. If the user forgets to turn on the main power switch (not shown), it is preferable that the main power be turned on when the time comes. On the other hand, the user may really want to turn off the main power. Here, it is assumed that when a main power switch (not shown) is turned off, the main power is not turned on by operation control of the CPU unit 4.

Reference numeral 5 denotes a program ROM section for storing a program for controlling the CPU section 4 so that the control section 3 and the CPU section 4 sequentially read the program from the program ROM 5. However, description of this operation is omitted. Reference numeral 6 denotes a volatile memory unit for storing reproduction data and the like output from the wireless reception unit 2.

Reference numeral 7 denotes a display unit for displaying image data and character data stored in a temporary storage unit (not shown) in the control unit 3 on a screen. 8 is an operation unit,
It is composed of buttons and the like for the user to appropriately operate. In the present embodiment, in particular, a button (not shown) for setting and canceling the time in the timer unit 12 described later is prepared.

Reference numeral 9 denotes a vibration motor which vibrates when a call is made from a base station (not shown) through the antenna 1 to notify the user of the call. Reference numeral 10 denotes a sounding body which emits a sound when a call is made from a base station (not shown) through the antenna 1 to notify the user of the call. Reference numeral 11 denotes a clock oscillating unit that supplies a clock at a constant interval to the CPU unit 4.

Reference numeral 12 denotes a timer section for setting the timing for switching the power supplied from the CPU section 4 to the radio receiving section 2 and the control section 3 in accordance with the time set here, as will be described later. In the set time, a time at which the main power is turned off and a time at which the main power is turned on can be set. FIG. 2 is an explanatory diagram of power on / off.

In FIG. 1, the CPU section 4 is directly connected to a power supply E, and is always in an operating state. The CPU unit 4 is connected to the base of the transistor Tr. The power supply E is connected to the emitter side of the transistor Tr, and the wireless receiving unit 2 and the control unit 3 are connected to the collector side of the transistor Tr. Note that here, the transistor Tr is assumed to be a PNP transistor, but may be an NPN transistor, and is not limited to a switching element that can be turned on and off similarly to a PNP transistor.

Further, the CPU unit 4 allows the transistor Tr to conduct by supplying a current a to be supplied to the base of the transistor Tr for a predetermined time in accordance with the clock oscillated from the clock oscillating unit 11 to make the transistor Tr conductive. The control unit 3 is turned on. That is, power is supplied by intermittent reception control as in the conventional case.
In the present embodiment, in particular, when the stop time set in the timer unit 12 comes, the intermittent reception control operation is interrupted, the main power is turned off, and the set start time comes. Sometimes, the intermittent reception control operation is restarted to turn on the main power supply. Therefore, the CPU unit 4
Does not output the current a during the period from the stop time to the start time, and sets the wireless receiving unit 2 and the control unit 3 to the operating state during that period. Therefore, it is possible to switch on / off the main power supply according to the set time.

Next, how the power consumption is reduced when the operation is controlled as described above will be described with reference to a time chart. FIG. 3 shows a time chart. It is assumed that a power switch (not shown) is turned on throughout the day, and a case where an intermittent reception system in which a main power is turned on and off at a timing of 1 second pulse at 30 second intervals is assumed. Note that 24 hours = 86400 seconds.

A user operates the operation unit 8 to set a stop time and a start time in the timer unit 12 via the control unit 3 and the CPU unit 4. Here, it is assumed that there is an interval of 8 hours = 28800 seconds between the stop time and the start time. Then, the timer unit 12 notifies the CPU unit 4 when the stop time or the start time comes. First, when the stop time comes, the CPU section 4 cuts off the base current a of the transistor Tr (see FIG. 2), turns off the main power supply and maintains this state, and in FIG. When the start time comes, the base current a is supplied to turn on the main power supply. That is, even if a main power switch (not shown) is on, the main power can be turned on and off.

Therefore, according to the first embodiment,
For example, a user who does not use the pager system at night or the like can save the trouble of turning on and off the power switch for each non-use time zone, thereby improving the usability. Further, for example, when the pager system is not used for 8 hours from 10 o'clock to 6 o'clock in the morning, the user operates the operation unit of the pager terminal device in advance to operate the main power supply of the pager terminal device only during this time zone. The main power supply is automatically turned off at night and can be turned on again the next morning by selecting a state setting such that is turned off. Therefore, since the power of the pager terminal is turned off for 8 hours in one day, the effect that the user does not need to frequently turn off the main power switch can be obtained, and unnecessary power consumption during this time can be eliminated. become able to. Therefore, an effect of not promoting reduction in the duration of the dry battery can be expected.

Second Embodiment Hereinafter, differences from the first embodiment will be mainly described. It is assumed that the block configuration is the same as that of the first embodiment described with reference to FIG. In the first embodiment, the main power of the pager terminal device itself is controlled to be turned on / off by the function of the timer unit 12 provided in the pager terminal device. However, if a call is made during a time period in which it is assumed that the pager terminal is not used, the call cannot be received.

Therefore, in the second embodiment, the main power supply is not turned on / off during the time set in the timer section 12, but the radio wave is received during the set time, and the contents are stored in the volatile memory. The operation of the sounding body 10, the vibration motor 9 and the lamp (not shown) is individually stopped through the control unit 3 at that time, and the operation of the display unit 7 and the illumination circuit (not shown) for the display are stopped. The operation can also be individually stopped through the control unit 3 in the same manner.

Therefore, in the second embodiment, the main power supply is always in the ON state, that is, the operations of the radio receiving unit 2 and the control unit 3 continue. It should be noted that whether or not the call message is stored in the volatile memory unit 6 is checked by the user by displaying the presence or absence and the content on the display unit 7 after the set time is over, and operating the vibration motor 9 and the sounding body 10. I will not let you know.

Therefore, according to the second embodiment,
When a call is made during the set time, the presence or absence of the call and the content can be confirmed thereafter, so that the notification operation does not have to be performed, and the power consumption is reduced by the amount of not performing the notification operation. The effect is obtained. Therefore, an effect of not promoting reduction in the duration of the dry battery can be expected. Third Embodiment Next, a pager system using the pager terminal devices of the first embodiment and the second embodiment will be described. In this pager system, a setter who sets the time in the timer section 12 of the pager terminal device transmits the set time to a pager base station facility (hereinafter, referred to as a “base station”) through a telephone network, and the base station transmits the set time. By transmitting the set time to the apparatus, the time is set in the timer section 12 of the pager terminal apparatus. The setter can be assumed to be a callee who owns the pager terminal device and a caller who sends a call message to the pager terminal device depending on the operation mode. In the following description, both are performed separately. FIG. 4 shows the concept of the pager system. -In the case where the setter is a called party holding a pager terminal device-First, the called party is a telephone terminal 14 connected to a wired telephone network.

Enter for Then, the base station 15 having received the set time information sets the pager terminal device 13
The signal processing unit 16 edits the time to be paused and the time to be activated again as wireless data, and the wireless transmitter 1
It fires to the pager terminal device 13 via the antenna 9 and the antenna 20. Then, in the pager terminal device 13, the set time is set in the timer unit 12 as in the first embodiment or the second embodiment.

The timing of emitting the set time information may be performed at the same time when an instruction is inputted from the receiving telephone terminal 14b, or the set time information may be transmitted until the designated time for pausing. It is stored in the memory unit 18 and the signal processing unit 16
Is recognized, and the calling telephone terminal 14
When a call message of a third party is input from a, the set time information may be transmitted to the pager terminal device 13 together with the call message. In this case, if there is no call message from a third party, the set time information may be emitted immediately before the designated time. Therefore, in such a case, as in the first or second embodiment,
There is no need to prepare a button (not shown) for setting the time in the timer section 12 in the operation section 8 of the pager terminal device 13 and canceling the setting. -In the case where the setter is a caller who sends a call message to the pager terminal device-First, the caller of the call message transmits the call message by the telephone terminal 14a connected to the wired telephone network when the next call message is transmitted. A scheduled time for transmitting the call message is input and transmitted to base station 15. The base station 15 performs signal processing on set time information for turning on / off the main power supply of the pager terminal device 13 or suspending operations of the I / O elements such as the vibration motor 9 and the sounding body 10 other than the wireless reception unit 2 and the control unit 3. The data is edited as wireless data by the unit 16 and the wireless transmitter 19 and the antenna
0 to the pager terminal 13.
Then, in the pager terminal device 13, the timer unit 1 as in the first embodiment or the second embodiment is used.
2. Set the set time. Therefore, the called party does not need to be aware of the turning on / off of the main power of the pager terminal device 13, and can turn on / off the main power of the pager terminal device at the convenience of the caller.

In the case of the third embodiment, when the set time information is transmitted from the base station 15 to the pager terminal device 13, there is time information set last time.
Processing when the main power is turned off will be described. In such a case, the base station 15 is configured to store the set time information transmitted through the telephone network by the setter who sets the time in the timer section 12 in the memory section 18. When the new set time information is transmitted, it is stored in the memory unit 18 until the time when the main power is turned on based on the previous set time information. Processing is performed so that the new set time information is emitted to the pager terminal device 13. Therefore, the new set time information is reliably transmitted from the base station 15 to the pager terminal device 13.
