Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiving device which provides a one-way mobile communication service for notifying the owner of this device that there is a call, and more particularly to a selective call receiving device using a single individual number code. The present invention relates to a selective call receiving device capable of individually calling a call receiving device.

[0002]

2. Description of the Related Art Conventionally, as a selective call receiving device for carrying out a one-way mobile communication service for notifying the owner of the device that there is a call, a device as shown in FIG. 6 is known.

In the selective calling device shown in FIG. 6, a selective calling signal including an individual number code and a message code transmitted from a base station (not shown) is transmitted via the antenna 9 to the radio circuit 1.
0, and the received selective calling signal is demodulated by the demodulation circuit 11
It is demodulated by and is supplied to the control circuit 12. The control circuit 12 compares the individual number code included in the selective call signal with the individual number code of its own machine stored in the memory 13, and if they match, drives the speaker 15 via the amplifier circuit 14. Then, a ringing tone is generated from the speaker 15.
At the same time, the message code included in the received selective call signal is displayed on the LCD display 1 via the LCD driver 16.
7, and the message information corresponding to the message code is displayed on the display 17 as characters or symbols.

Control circuit 1 of the above-mentioned conventional selective reception calling device
The processing of No. 2 will be further described with reference to the flowchart shown in FIG. That is, when the selective calling number is received (step 100), it is checked whether the individual number code of the next received selective calling signal matches the individual number code of the own machine stored in the memory 13 (step 101).
When they match, the subsequent message code is received (step 102), and the speaker 15 calls and the LCD display 17 displays a message (step 10).
3). If the individual number codes do not match in step 101, this process is terminated without performing the receiving, calling, and displaying operations.

By the way, in such a conventional selective receiving / calling apparatus, the call is made by inputting the individual number code of the called party from a telephone at the calling side (not shown). Since different individual number codes are assigned to each, for example, when it is desired to individually call a specific number of selective call receiving devices, it is necessary to know the individual number codes as many as the desired selective call receiving devices. Is. Here, since this individual number code is composed of a multi-digit number string like a normal telephone number, it is troublesome to store a large number of this multi-digit number string, and the telephone of the calling side is also troublesome. Therefore, it is very troublesome to input a large number of multi-digit numbers.

[0006]

As described above, in the conventional selective call receiving device, the individual number codes of the individual selective calling receiving devices are different from each other, so that it is desired to individually call a large number of specific selective calling receiving devices. In this case, it is necessary to know the individual number codes corresponding to the number of selective call receivers to be called, and there is a problem that the call operation takes time when it is desired to call a specific number of selective call receivers individually. It was

Therefore, an object of the present invention is to provide a selective call receiving device capable of individually calling a specific number of selective call receiving devices by a simple operation.

[0008]

In order to achieve the above object, the present invention receives a selective calling signal including an individual number code and a message code transmitted from a base station, and the individual number code of the own device is received. The selective call receiving device, which receives the message code and makes a selective call when it matches the individual number code, has a storage means for storing an individual code for identifying itself in addition to the individual number code. The selective calling is performed when the individual number code included in the signal matches the individual number code of the own machine and the individual code included in the message code matches the individual code stored in the storage means. ..

[0009]

In addition to the individual number code assigned to the own device, an individual code for identifying the own device is stored in the storage means, and the individual number code matches the individual number code of the own device and is included in the message code. When the code matches the individual code stored in the storage means, the selective calling is performed.

The switch group 23 is configured so that it can be set by mode switching.

Before explaining the operation of this embodiment, a selective call system constituted by using the selective call receiving apparatus of this embodiment will be explained.

Referring to FIG. 2, the selective call system of this embodiment has a central control station 5 connected to a public telephone network 3 and a plurality of radios connected to the central control station 5 and assigned different service areas. Base stations 6-1, 6-
2, ... 6-n, the selective call receiving device 8 of the present embodiment performs selective call from the telephone 1 connected to the public telephone network 3 to receive the selective call as the call destination. The individual number code of the device 8 and the message code transmitted to the selective call receiving device 8 are input, and the individual number code and the message code are transmitted to the central control station 5 of this system via the local exchange of the public switched telephone network 3. , The central control station 5 sends the selective call signal composed of the individual number code and the message code to the radio base stations 6-1, 6-2, ... 6-n.
, And each wireless base station 6-1, 6-2, ... 6-n transmits a selective call signal including an individual number code and a message code. The selective call receiving apparatus 8 of this embodiment shown in FIG. 1 has the radio base stations 6-1, 6-2, ... 6-n.
The selective call signal composed of the individual number code and the message code transmitted from is received.

By the way, in this embodiment, the same individual number code is assigned to a plurality of selective calling receivers, and the message code is an individual code for identifying the plurality of selective calling receivers. It is included.

FIG. 3 shows an example of the message code used in this embodiment. In this embodiment, a two-digit individual code IC is used as the individual code, and a message code MC in which the two-digit individual code IC is followed by the message code MC is used.

In this selective call system, when the selective call receiver 8 is called from the telephone 1, the individual number code corresponding to the selective call receiver 8 is input from the telephone 1 and the public telephone network 3 is used. After being connected to the central control station 5, the telephone corresponding to the selective call receiver 8 from the telephone 1
The digit individual code IC is input, the message code MC is subsequently input, and when the input of the message code MC is completed, the end code E is input by pressing the "#" key, for example. As a result, the central control unit 5 forms a selective call signal including an individual number code of the selective call receiving device 8 and a message code having a two-digit individual code IC at the head portion, and the selective call signal includes a plurality of radio base stations. It is transmitted from the stations 6-1, 6-2, ... 6-n.

Returning to FIG. 1, the selective call receiving apparatus shown in FIG. 1 has the radio base stations 6-1, 6-2, ... 6 shown in FIG.
When the selective call signal from -n is received, the CPU 18 determines whether the individual number code included in the received selective call number matches the individual number code of its own machine stored in the first storage area 22a of the memory 22. If they match, then the individual code IC at the beginning of the message code following this individual number code is stored in the second storage area 22b of the memory 22 (the individual code (individual code)). It is checked whether or not it matches the code IC), and if it matches, the above-mentioned notifying means gives a notification according to the mode designated by the mode changeover switch 23a of the above-mentioned switch group 23, for example.

Next, the operation of the selective call receiving apparatus of this embodiment shown in FIG. 1 will be further described with reference to FIG.

In FIG. 4, first, when the selective calling signal is received, the CPU 18 fetches the individual number code included in the selective calling signal from the demodulation output of the demodulation circuit 11 via the bus 19 (step 200). Then, the CPU 18
Reads out the individual number code of the own device from the first storage area 22a of the memory 22 and compares the read individual number code of the own device with the fetched individual number code (step 210). Then, when the individual number code of the own machine matches the fetched individual number code (step 220), CP
The U18 takes in the message code following it from the demodulation output of the demodulation circuit 11 (step 230), then reads the individual code of the own machine from the second storage area 22b of the memory 22, and reads the individual code of the own machine. The code is compared with the individual code included at the beginning of the fetched individual number code (step 240). Here, when the individual code of the own machine and the individual code included at the beginning of the fetched individual number code match (step 250), the mode specified in advance by the mode changeover switch 23a of the input switch group 23 is used. Is called and displayed (step 260). That is, the notification that the ringing tone is output from the speaker 15 through the amplifier circuit 14, the notification that the characters and symbols are displayed on the display surface of the LCD display 17 through the LCD driver 16, and the LED 25 is caused to emit light through the LED driver 24. A notification or a notification that the vibration element 27 causes vibration via the vibration element driver 26 is performed.
The message code included in the message code received at the same time is supplied to the LCD display 17 via the LCD driver 16, and the message in characters or symbols is displayed on its display surface.

Here, this notification may be performed by a combination of these notification means. At this time, the mode changeover switch 23 of the input switch group 23
The message code may be stored in, for example, an EEPROM or a RAM with a battery backup by operating the operation switch 23b or the mode designated by a.

As described above, in this embodiment, the individual number code included in the selective call signal transmitted from the base station is the same as the own individual number code stored in advance in the first storage area 22a of the memory 22. Since the individual codes included in the head of the message code match and the individual code of the own machine stored in advance in the second storage area 22b of the memory 22 is matched, the selective calling is performed. Individual calls to a plurality of selective call receiving devices to which number codes are assigned can be performed easily and reliably. That is, when making an individual call to a plurality of selective call receivers to which the same call number is assigned, after inputting the individual number codes assigned to the plurality of selective call receivers, for example, two digits Just enter the individual code.

In this way, it is possible to make an individual call to a plurality of selective call receiving devices to which the same call number is assigned, by a simple operation.

By the way, as one of the various modes by the mode changeover switch 23a of the above-mentioned input switch 23, for example, a first mode in which a plurality of selective call receiving devices to which the same individual number code is assigned are simultaneously called. A second mode for individually calling the plurality of selective call receiving devices may be set. For example, when the first mode is set, a plurality of selective call receiving devices are simultaneously informed by simply inputting the same individual number code, and when the second mode is set, By thus inputting the individual number code and the individual code, only one selective call receiving device identified by the individual code is configured to perform the notification operation.

In such a case, in the first mode, all the people carrying the selective call receiving device to which the same individual number code is assigned only need to input the individual number code. In addition, in the second mode, the individual calls of a plurality of persons carrying pagers to which the same individual number code is assigned are addressed to the person who wants to call the individual number code subsequently. All you have to do is enter the individual code. This mode switching is performed by the mode switching switch 2 of the input switch group 23 described above.
The person carrying the pager should do it at 3a. By doing so, it is possible to selectively use simultaneous call and individual call.

In this embodiment, as shown in FIG. 3, the two-digit individual code is added to the beginning of the message code. However, as shown in FIG. 5A, the individual code is added. The discrimination code S may be inserted between the IC and the message code MC. In this case, the individual code IC having an arbitrary number of digits can be used. For example, when the number of selective call receiving devices to which the same individual number code is assigned is 10 or less, one digit can be used as the individual code IC.
Further, as shown in FIG. 5B, a control code CC is inserted before the individual code IC, and the control code controls whether or not the individual code IC subsequent to the individual code IC is called. Good. With such a configuration, the above-described mode switching between the first mode and the second mode on the selective call receiving device side becomes unnecessary.

[0030]

As described above, according to the present invention,
The same individual number code is assigned to a plurality of selective call receivers, and the individual code for identifying any of the plurality of selective call receivers is included in the message code following this individual number code to selectively call. Since the individual number code included in the signal matches the individual number code of the own machine, and the individual code included in the message code matches the individual code stored in the storage means, the selective calling is performed. In this way, it is possible to make an individual call to a plurality of selective call receiving devices to which the same individual number code is assigned by a simple operation.
