BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiving device that performs a call when an individual number code included in a selective call signal transmitted from a base station matches its own individual number code. The present invention relates to a selective call receiving device that sets a plurality of individual number codes for the device and intermittently receives selective call signals from base stations in correspondence with the individual number codes.

2. Description of the Related Art Conventionally, a plurality of individual number codes are set for one selective call receiving device, a selective call signal transmitted from a base station is received, and an individual number included in the received selective call signal is set. A selective call receiving device has been proposed that makes a call when the code matches one of its own individual number codes.

[0003] In this selective calling device, for example, two individual number codes are set for one selective call receiving device: an individual number code A for calls from work and an individual number code B for calls from home. However, it is configured to make a call even when a selective call signal containing any individual number code is received.

By the way, in such a selective calling device, a plurality of individual number codes are divided into a plurality of groups, and intermittent calls are made from the base station to the individual number codes belonging to this group for each group, and each selective call is The device is configured to perform intermittent reception in which it intermittently receives only the selective call signal of the group to which the individual number code is set. In other words, the selective calling device supplies power to the radio circuit only while the base station is transmitting the selective calling signal of the group to which the individual number code belongs, and the selective calling device supplies power to the radio circuit only while the selective calling signal of the group to which the individual number code belongs is transmitted from the base station. While the selective call signal is being transmitted from the base station, the power supply to the radio circuit is turned off, thereby reducing the current consumption from the battery of the selective call device, which is the power source, and extending the life of the battery. ing.

However, if a plurality of individual number codes are set for one selective call receiving device, and the groups to which each individual number code belongs are different, the time required to supply power to the radio circuit becomes longer; This shortens the life of the battery of the selective calling device, which is the power source.

For example, as mentioned above, two individual number codes, individual number code A for calls from work and individual number code B for calls from home, are set for one selective call receiving device, If the groups to which individual number code A and individual number code B belong are different, while the selective call signal for the group to which individual number code A belongs is being transmitted from the base station, and the selective call signal for the group to which individual number code B belongs It is necessary to supply power to the radio circuit both while the code is being transmitted from the base station, and when multiple individual number codes are set and belong to many groups, the current consumption due to intermittent reception is mostly reduced. No savings can be expected.

By the way, in a case where two individual number codes are set for a single selective call receiving device: an individual number code A for calls from work and an individual number code B for calls from home. For example, while working at the company, it is necessary to call the individual number code A for calls from work, but it is not necessary to call the individual number code B for calls from home; , it is necessary to call individual number code B for calls from home, but it is not necessary to call individual number code A for calls from work, and so on. Bands may vary.

[0008] However, in the conventional selective calling device, calls are always accepted for all individual number codes, so if the individual number codes belong to many groups, it is hardly possible to reduce current consumption through intermittent reception. Ta.

[0009]

[Problems to be Solved by the Invention] As mentioned above, the conventional selective calling device always calls all the individual number codes, even though the time periods during which calls are required for each individual number code are different. Therefore, if individual number codes belong to many groups, it is hardly possible to reduce current consumption through intermittent reception.

Therefore, in the present invention, even when a plurality of individual number codes are set and the individual number codes belong to a large number of groups, the battery life can be extended, and the selective call function allows necessary calls. The purpose is to provide a receiver. [Structure of the invention]

[0011]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a system for transmitting a selective call signal containing an individual number, which is intermittently generated from a base station for each group to which the individual number code belongs, in an intermittent cycle. An individual number in which multiple individual number codes are set in a selective call receiving device that receives intermittently in synchronization with the received selective call signal and makes a call if the individual number code included in the received selective call signal matches its own individual number code. a setting means; a time zone means for setting a time zone during which reception of the selective calling signal is permitted in correspondence with the individual number code set by the individual number setting means; and a time during which reception is permitted by the time zone means. The present invention is characterized in that it includes an intermittent reception permitting means for permitting intermittent reception of a selective calling signal containing a corresponding individual number code only for the band.

0012

[Operation] In this invention, a time period is set for each individual number code in which the reception of a selective call signal that includes the individual number code is permitted, so that the life of the battery that is the power source is extended without impairing necessary calls. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention.

The selective call receiving device of this embodiment includes an antenna 1, a radio circuit 2 that receives a selective call signal from a base station (not shown) via the antenna 1, and an individual number code and message information included in the selective call signal. a demodulation circuit 3 that demodulates the code, a code matching circuit 4 that matches the individual number code included in the selective call signal demodulated by the demodulation circuit 3 with a plurality of individual number codes registered in the storage unit 5, and a plurality of individual number codes. a storage unit 5 for registering the selective calling device, a control circuit 6 for controlling this selective calling device, a drive circuit 7 for driving the speaker 8 by the output of the control circuit 6, a speaker 8 for generating a ringing tone from the drive circuit 7, and an output of the control circuit 6. a display driver 9 that drives the display 10, a display 10 that displays message information included in the selective call signal, a reception time zone setting section 11 that sets a reception permitted time zone corresponding to each individual number code, and time information. It consists of a clock circuit 12 that generates .

The base station (not shown) is configured to divide the individual number codes set in each selective call receiving device into a plurality of groups and sequentially transmit selective call signals for each group. The control circuit 6 of each selective call receiving device detects the timing of this selective call signal via the antenna 1, the radio circuit 2, the demodulation circuit 3, and the code matching circuit 4, and uses this timing to supply power to the radio circuit 2. to perform intermittent reception.

That is, the control circuit 5 controls the individual number codes registered in the storage section 5, the reception permission time period for each individual number code set in the reception time period setting section 11, and the output from the clock circuit 12. Refers to the time information and determines the individual number code that is permitted to be received for each time period,
Intermittent reception in which power is supplied to the radio circuit 2 to perform reception operations only during the time allocated to this individual number code, and power supply to the radio circuit 2 is turned off and reception operations are not performed outside of that time. I do. Next, the operation of the selective call receiving apparatus configured as described above will be explained.

When the power supply to the radio circuit 2 is turned on by the control circuit 6, a selective call signal transmitted from a base station (not shown) is transmitted to the radio circuit 2 via the antenna 1.
The signal is received by the demodulator 3, demodulated by the demodulator 3, and guided to the code matching circuit 4.

The code matching circuit 4 matches the individual number code included in the transmitted selective call signal with a plurality of individual number codes of the own machine stored in advance in the storage unit 5.

If the two match, the control circuit 6 drives the drive circuit 7 to cause the speaker 8 to generate a sound signal. The control circuit 6 also controls the display driver 9 based on message information included in the selective call signal from the base station.
is driven to display message information on the display 10. This allows the holder of this selective calling device to recognize that he or she has been called.

Here, when the power supply to the radio circuit 2 is turned off by the control circuit 6, the base station sends a message including the individual number code registered in the storage unit 5 of its own selective call receiving device. Even if a selective call signal is sent out, this selective call signal is not received and no response is made.

According to such a configuration, calls to each individual number code are selectively prohibited or permitted depending on each time period in accordance with the settings of the reception time period setting section 11.
Even if a plurality of individual number codes set in this selective call receiving device belong to different groups, the time for supplying power to the radio circuit 2 is shortened, which reduces the lifespan of the battery that is the power source of the selective call receiving device. can be made longer. The operation of this embodiment will be further explained with reference to the timing charts of FIGS. 2 and 3.

FIG. 2 shows that three individual number codes NA, NB, NC are stored in the storage unit 5 of the selective call receiving device of this embodiment.
is registered, and the reception time zone setting unit 11 prohibits calls from 8:00 AM to 5:00 PM for the individual number code NB, and from 5:00 PM to 8:00 AM for the individual number codes NA and NC. This shows the case where the settings are set to prohibit calls until the end. Moreover, FIG. 3 corresponds to the operation of the conventional device, and shows three individual number codes NA.
, NB, and NC are always allowed to call.

To simplify the explanation, it is assumed here that the base station generates selective call signals for the three individual number codes NA, NB, and NC once every hour. In reality, the base station generates a selective call signal at a much shorter period, and the selective call receiver turns on the radio circuit in response to this and performs intermittent reception.

In this case, each individual number code NA, NB
, NC are the reception times of selective calling signals from the base station, respectively, as A, B, and C. In the case of the conventional device shown in FIG. 3, the total time that the radio circuit is on in one day is 2
4(A+B+C).

On the other hand, in the case of this embodiment shown in FIG.
+C)x+B(24-x). Here, x is the time during which calls to the individual number code NB are prohibited, and in the case of FIG. 2, x=9. This value x is the individual number code N
This varies depending on the setting of the prohibited time period for calls to B.

By the way, 24(A+B+C)>(A+C
)x+B(24-x), this embodiment is effective, but when the above equation is expanded, 24A+24C>Ax+Cx-Bx. Here, even if x=24, it can be seen that the total time during which the wireless circuit 2 is on in one day is shorter by 24B in this embodiment than in the conventional device. Also, A, B, C,
Since x is never negative, similarly when x<24, the total time that the radio circuit 2 is turned on in one day is shorter in this embodiment than in the conventional device.

In the above embodiment, three individual number codes are set for one selective call receiving device, but when two individual number codes are set for one selective call receiving device. , and four or more individual number codes can be similarly configured.

[0028]

[Effects of the Invention] As explained above, according to the present invention,
Since the system is configured so that the callable time zone can be set for each individual number code, the power-on time of the wireless circuit can be shortened, and the life of the built-in battery can be extended compared to the conventional system. In addition, depending on how each individual number code is used, there are no calls to a predetermined call number during a predetermined time slot, so if you set the callable time slot according to each call number, you can Detailed services become possible and the functionality of this type of device can be increased.
