Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention, for example, a selective call receiver, receives an individual number code transmitted from a base station, and receives the individual number code from a base station. The present invention relates to a wireless communication device that recognizes a call if it corresponds to its own device.

(Prior Art) A selective calling system is known as a mobile radio system that calls a radio communication device using an individual number code. The selective calling system uses selective calling signals as shown in FIG. 6, for example.

That is, one frame of the selective call signal is time-divided into a plurality of groups (n groups in the figure) as shown in (1), and these groups are further divided into a synchronization word and a plurality of call words (n groups in the figure) as shown in (b). m words). In addition, these call words are the individual number code (ID code) of the selective call receiver as shown in (C),
It consists of a message code.

When calling a desired selective call receiver, the calling party dials the telephone number corresponding to the selective call receiver to call the base station and sends message information to the base station. Then, the base station first generates an ID code previously assigned to the selective call receiver and a message code that encodes the message information. Then, the ID code and the message code are inserted into empty call words of the group to which the selective call receiver belongs among the plurality of groups constituting one frame, and then transmitted.

On the other hand, FIG. 7 shows an example of the configuration of a selective calling receiver. In the figure, a selective calling signal transmitted from a base station is received by a radio circuit 2 via an antenna 1, demodulated by a demodulation circuit 3, and introduced into a control circuit 4. The control circuit 4 controls the I included in the demodulated selective call signal.
The D code is compared with the own ID code stored in advance in the individual number code memory (ID-ROM) 5. When it is detected through this comparison that the two codes match, it is recognized that a call has occurred to the own machine, and a sound signal is supplied to the speaker 7 via the drive circuit 6. Therefore, a ringing tone is generated from the speaker 7, thereby notifying the holder of the occurrence of the ringing. In addition, the above ringtone can be heard by pressing the stop switch 1.
It is stopped by pressing 1.

Further, when a match between the ID codes is detected, the control circuit 4 performs error correction processing on the message code received following the ID code and then decodes the message code, and furthermore, the control circuit 4 decodes the message code received following the ID code, and furthermore, the control circuit 4 decodes the message code received following the ID code. is supplied to the display drive circuit 8. Therefore, message information is displayed on the product display (LCD) 9. Therefore, the holder can know the message from the caller by looking at the LCD 9 when the call is announced. Further, the received message code is transferred to and stored in the message memory (M-RAM) 10. The message code stored in this M-RAMIO is later read out by operating the display switch 12 and redisplayed on the LCD 9.

Further, the control circuit 4 outputs a control signal for battery saving to the battery saving circuit 13 at a predetermined timing while waiting for a call, thereby controlling the operating state of the radio circuit 2 and the demodulation circuit 3. For example, if the group to which the own device belongs is group 2, as shown in FIG. During the reception period, the wireless circuit 2
Then, the power supply to the demodulation circuit 3 is cut off and the demodulation circuit 3 is set to a non-operating state. In this way, the radio circuit 2 and the demodulation circuit 3 operate only during the reception period of the group to which the device belongs, so that the power consumption of the battery 14 is reduced accordingly. For example, if the number of groups in one frame is n groups, the power consumption is 1/n.

Recently, it has been considered that a single selective call receiver has a plurality of ID codes so that calls can be made using each of these ID codes. In this way, for example, if you have two ID codes A and B, you can use ID code A for calls from work and ID code B for calls from home. can.

(Problem to be solved by the invention) However, in this type of conventionally considered system, the selective calling receiver always receives all IDs as long as the power is turned on.
The group to which the code belongs is received.

This has caused the following problems.

That is, depending on the time of day, the receiver always receives information about the group to which the ID code belongs, which it does not actually need to receive. For example, if ID code A is used for calls from work and ID code B is used for calls from home as described above, when the receiver owner is at work, Above ID
Although code A reception monitoring is virtually unnecessary,
The reception of this ID code A is monitored. Furthermore, although it is virtually unnecessary to monitor the reception of ID code B when the owner is at home,
Reception monitoring is also performed.

Therefore, the receiver makes practically unnecessary call notifications, and the holder has to perform operations such as stopping the ringer and stopping the display of message information each time, and these operations are extremely difficult. It was bothersome. Further, there is a problem in that power is wasted by receiving a reception group of ID codes that do not actually need to be received, thereby shortening the battery life.

Therefore, the present invention has focused on the above-mentioned circumstances, and has developed a wireless communication system that prevents unnecessary call notifications depending on the time of day, eliminates the need for troublesome operations, reduces wasteful power consumption, and extends battery life. The purpose is to provide communication equipment.

Another object of the present invention is to provide a wireless communication device that allows the owner to arbitrarily set the reception time period for each ID code.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention receives only the group to which the individual number code owned by the own device belongs among the selective call signals transmitted from the base station. In a wireless communication device that
The apparatus includes a storage means for storing information specifying a reception time period, and a control means. Then, in the storage means, specifying information for specifying whether or not to perform reception of a group to which the individual number code belongs, corresponding to a specific individual number code owned by the own aircraft, is stored in the storage means. The receiving operation of the group to which the specific individual number code belongs is controlled by the control means in accordance with the designation information stored in the storage means.

In order to achieve the above-mentioned other objects, another aspect of the present invention includes an input means for inputting information specifying a reception time zone, a storage means, and a control means. Then, corresponding to a specific individual number code owned by the own aircraft, designation information for specifying whether or not to perform reception of the group to which this individual number code belongs according to the time period is inputted using the input means. , is stored in the storage means, and the control means controls the reception operation of the group to which the specific individual number code belongs in accordance with the designation information stored in the storage means.

(Function) As a result, according to the present invention, reception monitoring of a specific ID code is performed only during a predetermined time period specified by designation information, and is not performed during other time periods. For this reason, for example, with regard to ID codes used for calls from work, reception will no longer be monitored during times when the holder is at work, that is, during times when calls are not expected to be made. , reception monitoring will be performed only during times when the user is away from work. therefore,
During the time period when the holder is in the office, no power is consumed to receive and monitor the specific ID code, which reduces power consumption and extends battery life. Furthermore, even if a person in the company mistakenly makes a call while the person is in the office, the receiver will not notify the user of the call. Therefore, in response to this call, the holder must
There is no need to perform operations such as stopping the sound or displaying the message. That is, it is possible to eliminate the need for troublesome response operations to meaningless calls.

According to another aspect of the present invention, the holder can arbitrarily input and set designation information related to the reception time period for a specific ID code using an input means. therefore,
If the owner behaves in a pattern different from the normal behavior pattern, by inputting the specified information in advance, the receiver can monitor the reception of specific ID codes without causing any problems. It becomes possible to perform control.

(Example) Next, the present invention will be explained using a selective call receiver as an example.

FIG. 1 shows the configuration of a selective call receiver in this embodiment. In this figure, the same parts as those in FIG. 7 are given the same reference numerals and detailed explanations will be omitted.

This selective call receiver includes a function switch 15 for specifying the input mode of reception prohibition information, a reception prohibition information memory (T-RAM) 16 for storing reception prohibition information,
It also newly includes a timer 17 with a clock function.

On the other hand, the control circuit 40 has, for example, a microprocessor as a main control section, and in addition to normal functions such as a battery saving control means, a verification means, a call notification control means, and a display control means, it also has a reception prohibition information input control means. 41 and reception time zone control means 42 are newly provided.

When the reception prohibition information input mode is specified by the function switch 15, the reception prohibition information input control means 41 inputs the reception prohibition time period inputted by the combined operation of the stop switch 11 and the display switch 12, with an ID code A,
This is stored in the T-RAM 17 in association with B. The reception time zone control means 42 controls the timer 17 while waiting for a call.
monitor the current time. Then, the current time is T
- When the reception prohibition time period stored in the RAM 17 comes, the reception operation of the group to which the corresponding ID code belongs is prohibited.

Next, the operation of the receiver configured as described above will be explained according to the control procedure of the control circuit 40. Note that the selective call receiver has two ID codes A and B, and these ID codes
Codes A and B are group 1. of selective call signals, respectively. The explanation will be given assuming that it belongs to group n.

In the call standby state, the control circuit 40 monitors in steps 2g and 2b whether or not the reception periods for group 1 and group n have arrived, respectively, as shown in FIG.
When it is confirmed that the reception period for group 1 or group n has come, the process shifts to reception control. The control circuit 40 also monitors the operation of the display switch 12 in step 2c and the function switch 15 in step 2d, and when it is confirmed that the display switch 12 has been pressed, the M-RAMI Display control of received message information stored in O is performed.

Further, when the operation of the function switch 15 is confirmed, the control circuit 40 shifts to input control of reception prohibition information.

Now, suppose that the holder presses the function switch 15 to set the reception prohibited time period for each ID code A and B. Then, the control circuit 40 enters the reception prohibition information input mode, and first monitors the re-operation of the function switch 15 in step 3a, as shown in FIG. 3(a). Then, if function switch 15 is not pressed, step 3
The process moves to step b, and here, for example, ID code A is selected and this ID code A is displayed on the LCD 9. Further, the operation and monitoring of the display switch 12 and stop switch 11 are performed using the steering wheel, knobs 3c and 3d, respectively. If the operation of these switches 1, 1, and 12 is not confirmed, the process returns to step 3a and repeats the above control.

In this state, assume that the holder presses the display switch 12 in an attempt to select an ID code different from the ID code currently displayed. Then, the control circuit 40 moves from step 3C to step 3e, selects another ID code B, and moves to step 3b. Therefore, the newly selected ID code B is displayed on the LCD 9. If the function switch 15 is pressed again during the above control operation, the system returns to the call standby state.

Assume that the holder presses the stop switch 11 with the desired ID code (for example, ID code A) selected. Then, the control circuit 40 moves from step 3d to step 3f, where it reads out the start time of the reception prohibited time period already stored in the T-RAM 16 corresponding to the ID code A, and displays it on the LCD 9. For this reason, for example, if the T-RAMI 6 currently stores information about a reception prohibited time period of "9:00 to 17:00", the LCD 9 will display "From 9:00". In addition, if the reception prohibition time zone corresponding to the above ID code B has not been set yet, "From 00:00" will be displayed on the LCD 9.
is displayed.

In this state, if the owner tries to change the above start time,
Assume that the display switch 12 is pressed. Then, the control circuit 40 moves from step 3g to step 31, where it increments the current start time stored in the T-RAMI 6 and advances it by one hour. Then, in step 3f, the start time after this change (for example, "from 10 o'clock")
is displayed on the LCD 9. Thereafter, the control circuit 40 similarly:
Each time the display switch 12 is pressed, the start time is advanced by one hour, and this advanced time is displayed on the LCD 9.

When the holder presses the stop switch 11 with the desired start time displayed, the control circuit 40 executes step 3.
Detect this at step 3j and proceed to step 3j shown in FIG. 3(b).
to move to. Then, in this step 3j, T-
The end time "until 17:00" from the information on the reception prohibited time zone stored in the RAM 16 is read out and displayed on the LCD 9. In this state, assume that the holder presses the display switch 12 in order to change the end time. Then,
The control circuit 40 moves from step 3k to step 3m, where it increments the current end time stored in the T-RAM 16 and advances it by one hour. Then, in step 3, the changed end time is displayed on the LCD 9. Thereafter, the control circuit 40 similarly controls the display switch 12 or 1.
Each time it is pressed, as in the case of the start time mentioned above,
The end time is advanced by one hour and this time is displayed on the LCD 9. When the setting of the end time is completed and the owner presses the stop switch 11, the control circuit 40 detects this operation in step 31 and determines that the setting of the reception prohibited time period has ended. Return to step 3a. In this way, the setting of the reception prohibited time period for one ID code A is completed.

Incidentally, when setting the reception time zone for ID code B, the same procedure as for ID code A is performed. Then, when the setting of the reception prohibition time period for each ID code A and B is completed and the holder presses the function switch 15, the control circuit 40 detects this operation in step 3a and enters a call standby state (call waiting state). Return to Figure 2).

On the other hand, assume that in the call standby state, the receiving period for group l to which ID code A belongs has now arrived. Then, the control circuit 40 shifts from step 2a in FIG. 2 to reception control shown in FIG. 4. In this reception control, first, in step 4a, reception prohibition information (reception prohibition time zone) corresponding to ID code A is read from the T-RAM 16, and the current time is read from the timer 17. Then, in step 4C, it is determined whether the current time falls within the reception prohibited time period. For example, assume that the reception prohibited time period is set to "10:00 to 14:00" and the current time is 9:00.

Then, in step 4C, it is determined that the current time does not fall within the reception prohibited time period, so the control circuit 40 moves to step 4d and outputs a reception operation instruction to the battery saving circuit 13 here. Therefore, the radio circuit 2
The output voltage VCC of the battery 14 is supplied to the demodulation circuit 3, and the radio circuit 2 and the demodulation circuit 3 are connected to each other as shown in FIG. 5(a).
Or, as shown in (C), it becomes a receiving operation state. During the reception period of group 1, the control circuit 40 performs verification control of the received ID code in step 4e, and performs notification control when the ID code matches the ID code A of the own device. Also, during the reception period of group 1, the control circuit 40 performs step 4.
At f, it is monitored whether the reception period has elapsed. When the receiving period has elapsed, the process moves to step 4g, where a non-receiving operation instruction is output to the battery saving circuit 13. Therefore, the supply of power supply voltage VCC to the radio circuit 2 and the demodulation circuit 3 is cut off, and as a result, the radio circuit 2 and the demodulation circuit 3 return to the non-receiving operation state.

On the other hand, if the current time is 11 o'clock, it is determined in step 4c that the current time falls within the reception prohibited time period. Therefore, the control circuit 40 determines that there is no need to receive group 1, and returns to the call standby state.

Therefore, the receiver does not perform the group 1 receiving operation as shown in FIG. 5(b).

Also, when the reception period of group n to which the D code B belongs comes, the control circuit 40 shifts to the reception control shown in FIG. 4. Then, it is determined in step 4C whether or not the current time falls within the reception prohibited time zone set for ID code B. If the current time does not fall within the reception prohibited time zone, the process shown in FIG. 5(a) is performed. or step 4 as shown in (b)
From step d to step 4g, normal reception, verification, and notification control is executed. On the other hand, if the current time falls within the above-mentioned reception prohibited time zone, the device returns to the call standby state without performing the reception operation for group n, as shown in FIG. 5(c).

Incidentally, FIG. 5(a) shows the operating state of the receiver when the current time does not fall within the reception prohibited time zones of ID code A and ID code B. Further, FIG. 5(b) shows the operating state of the receiver when the current time corresponds to the reception prohibited time period for ID code A but does not correspond to the reception prohibited time period for ID code B. Figure (c) shows the operating state of the receiver when the current time corresponds to the reception prohibited time period for ID code B but does not correspond to the reception prohibited time period for ID code A.

In this way, in this embodiment, a reception prohibited time period is set for each ID code A, B, and each ID code A,
Group 1 to which B belongs. In the reception period of n, it is determined whether the current time of the timer 17 falls within the above-mentioned reception prohibited time period, and if it is determined that it falls within the above-mentioned reception prohibited time period, no reception operation is performed and the non-reception operation state is maintained. That's what I do.

Therefore, during the time period when there is no need to receive ID codes A and B, the operation of receiving these ID codes A and B is not performed. Therefore, for example, if ID code A is used for calls from work and ID code B is used for calls from hypothetical companies, useless calls from work will not be received during the time when the holder is at work. Also, calls from home will not be received during times when the bearer is at home. Therefore, the holder does not have to perform troublesome operations such as stopping the sound or stopping the display of message information each time these unnecessary calls occur. Furthermore, since the reception operation is not performed during a time period when reception is not necessary, unnecessary power consumption can be reduced accordingly, thereby extending the life of the battery. In other words, the pantry saving effect can be further enhanced.

Furthermore, in this embodiment, since an input means for the reception prohibited time period is provided, each owner can arbitrarily set the reception prohibited time period according to his/her own activity schedule.

Note that the present invention is not limited to the above embodiments. For example, each ID code A in the above embodiment.

Set the reception prohibited time period for each B, and set the reception prohibited time period for each B.
Although the D code reception operation is not performed, it is also possible to set a reception permission time period and perform the ID code reception operation only in this time period. Further, the reception prohibited time period or the reception permitted time period may be set only for some ID codes.

Furthermore, the reception time period may be set not only in units of hours but also in units of minutes or seconds, or may be set in units of days, weeks, months, or years.

Furthermore, the present invention can be similarly applied to other mobile radio communication devices, such as car telephones, mobile telephones, and cordless telephones, in addition to selective call receivers.

In addition, the structure and input procedure of the input means for specifying information on the reception time zone, the control procedure and control contents of the reception time zone control means, etc. can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, the present invention includes a storage means for storing information specifying a receiving time period, and a control means. Then, in the storage means, specifying information for specifying whether or not to perform reception of a group to which the individual number code belongs, corresponding to a specific individual number code owned by the own aircraft, is stored in the storage means. The receiving operation of the group to which the specific individual number code belongs is controlled by the control means in accordance with the designation information stored in the storage means.

Therefore, according to the present invention, unnecessary call notifications can be prevented depending on the time of day, making troublesome operations unnecessary, and unnecessary power consumption can be reduced to extend battery life. A wireless communication device can be provided.

Another aspect of the present invention includes an input means for inputting information specifying a reception time zone, a storage means, and a control means. Then, corresponding to a specific individual number code owned by the own aircraft, designation information for specifying whether or not to perform reception of the group to which this individual number code belongs according to the time period is inputted using the input means. , is stored in the storage means, and the control means controls the receiving operation of the group to which the specific individual number code belongs in accordance with the designation information stored in the storage means.

Therefore, according to the present invention, troublesome operations can be made unnecessary, wasteful power consumption can be reduced, and battery life can be extended. A wireless communication device that can arbitrarily set a time zone can be provided.
