Abstract

PURPOSE:To surely confirm unread message by distinguishing a form of a call notice when an unread message is in existence from that when not in existence when the radio selective calling receiver is called. CONSTITUTION:When an ID coincidence signal is outputted from a decoder 3, a message control section 6 of a control section 5 retrieves a message stored in a message memory 8. When an unread message is detected, an unread notice generating signal is sent and when not detected, a usual notice generating signal is outputted. A notice drive section 9 outputs a usual/unread notice drive signal to a notice section 10 in response to the usual/unread notice generating signal to generate a discontinuous tone/continuous tone. Thus, the presence of an unread message is automatically recognized at every call notice.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver, and more particularly to a radio selective call receiver having a function of notifying the presence of a message which has not been displayed on the display unit although it has been received, that is, an unread message. The present invention relates to a radio selective call receiver.

[0002]

2. Description of the Related Art Conventionally, a radio selective call receiver of this type is
When the ID number of the user and the calling signal match, a plurality of calling notification modes, that is, generation of a notification sound through a speaker, generation of vibration by a vibrator, or LED
Blinks the light to notify the wearer that he is being called.

When the carrier recognizes that he / she is being called by the above-mentioned call notification, he / she stops the call notification by operating a switch or the like.

When the call notification is stopped, the radio selective call receiver causes the display function to display the message received following the call signal so that the carrier recognizes the message.

However, if the carrier does not notice that he / she is being called, does not operate a switch or the like, and does not stop the call notification, the radio selective call receiver will notify the call after a certain period of time. Stop automatically.

[0006] The radio selective call receiver does not display a message on the display function as an unread message because the carrier does not notice that he / she is being called after automatically stopping the call notification. The message is stored in the storage means.

The unread message stored in the storage means is confirmed by the operation of the means for the wearer to confirm the unread message, for example, by pressing the switch.

However, in order for the carrier to confirm the unread message, it is necessary to operate a switch or the like,
It has the problem of being very annoying. Further, the unread message stored in the storage means has a limit of the storage capacity of the storage means, so that an old one may be erased, and the carrier must confirm the unread message. There is a problem that you can not.

In order to solve the above-mentioned problems, for example,
Japanese Utility Model Application Laid-Open No. 2-43037 describes a radio selective call receiver which notifies the presence of an unread message by a notification sound at a predetermined time interval.

[0010]

However, although the technique described in the above publication certainly solves the technical problem of the confirmation of unread messages and the deletion of unread messages, There is a problem in that the internal configuration becomes complicated because a clock circuit for clocking time is required. Particularly, in recent years, with the downsizing of radio selective call receivers, the complication of the internal structure becomes a fatal drawback. Also, in addition to being notified when the radio selective call receiver itself is called, the presence of an unread message is notified at predetermined time intervals, so that when the carrier is attending a conference, etc. However, there is also a problem that a notification sound is emitted at regular time intervals, which disturbs the conference.

The object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a radio selective call receiver which distinguishes the call notification mode when the radio selective call receiver itself is called, depending on whether an unread message exists or not.

[0012]

In order to achieve the above object, a radio selective call receiver with an unread message notification function according to the present invention includes an antenna, a radio section for demodulating a received signal, and an ID-ROM. A decoder, a switch for requesting stoppage of call notification, display means for displaying a message, and notification means for making call notification.
Further, the radio selective call receiver with an unread message notification function of the present invention stores a message included in a digitized demodulated signal output from a decoder by distinguishing it between an unread message and a read message. Have. Furthermore, the radio selective call receiver with the unread message notification function according to the present invention,
If an unread message is present in the message memory when the ID match signal output from the decoder is input, control is performed so that an unread message is issued. It has a control part which controls so that it may notify. Furthermore, when the switch is pressed and there is a request to stop the notification,
It controls to stop the unread notification or the normal notification, displays the message on the display unit, stores it as a read message in the message memory, and if the switch is not pressed after a certain period of time, It has a function of controlling the read notification or the normal notification to be stopped and storing it in the message memory as an unread message.

[0013]

Since the radio selective call receiver with the unread message notification function according to the present invention has the above configuration, the control unit can search whether or not there is an unread message in the message memory. The carrying of the call notification can be changed depending on whether the read message is present or not.

[0014]

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a radio selective call receiver with an unread message notification function according to an embodiment of the present invention. In the figure, an antenna 1 receives a radio signal from a radio base station (not shown) and transmits the received signal to a radio unit 2
Output to. The radio unit 2 amplifies, demodulates, and shapes the waveform of the received signal from the antenna 1, and outputs the demodulated signal. ID-
The ROM 4 is composed of a P-ROM and stores its own predetermined ID number.

The decoder 3 converts the demodulated signal from the radio section 2 into a digital signal and detects a calling signal included in the digitized demodulated signal. Further, the decoder 3 detects the match between this calling signal and the ID number stored in the ID-ROM 4, and outputs the ID match signal and the digitized demodulated signal when they match. The message memory 8 is composed of a RAM, and stores the messages included in the digitized demodulated signal by distinguishing between unread messages and read messages.

The control unit 5 is composed of a general-purpose microprocessor, and has a message control unit 6 and a switch detection unit 7.
Have and.

The message control unit 6 receives from the decoder 3 I
When the D match signal is input, the message stored in the message memory 8 is searched. That is, this search is a search of whether or not an unread message is stored. Since the leading bit of the unread message is set to 1, the code of the leading bit stored in the message memory 8 is searched. By doing so, the unread message is detected. When the message control unit 6 detects an unread message from the message memory 8, it sends an unread notification generation signal, and outputs a normal notification generation signal when no unread message is detected. The unread notification generation signal and the normal notification generation signal described above are distinguished by a 2-bit identification signal. Here, the unread notification generation signal is the digital signal “0”.
1 "and the normal notification generation signal is a digital signal" 1 ".
0 ". The message control unit 6 uses a sound to notify the wearer that the radio selective calling receiver itself is being called. When input from the unit 7, the notification stop signal is output and the message included in the digitized demodulated signal is output to the display drive unit 12. This notification stop signal is a 2-bit identification signal.
The message control unit 6 outputs the message to the display drive unit 12, adds 0 to the first bit of the message, outputs the message to the message memory 8, and stores the read message. The message control unit 6 does not output the notification stop signal when the switch detection signal is not input, but the message control unit 6 does not output the notification stop signal when the time-up signal from the switch detection unit 7 is input. When the message control unit 6 outputs the notification stop signal, the message control unit 6 adds 1 to the first bit of the message included in the digitized demodulated signal, outputs it to the message memory 8, and stores it as an unread message.

The switch detector 7 monitors the pressing of the switch 11 and outputs the above-mentioned switch detection signal when the switch 11 is pressed. On the other hand, the switch detector 7
Has a timer therein, and outputs the above-mentioned time-up signal when the switch 11 is not pressed even after a certain time has elapsed since the control unit 5 input the ID match signal.

The switch 11 is a push button type switch and is pressed when the wearer notices that he is calling.

The display drive unit 12 drives the display unit 13 to display the message output by the message control unit 6 on the display unit 13. The display unit 13 is composed of a liquid crystal display, and the message control unit 6 outputs the message. Display a message.

The notification drive unit 9 inputs the unread notification generation signal or the normal notification generation signal output from the message control unit 6, and outputs the unread notification drive signal or the normal notification drive signal having different calling patterns. .

The notification unit 10 is composed of a speaker,
Based on the calling pattern of the unread notification drive signal output by the notification drive unit 9 or the normal notification drive signal, different call notifications exist when an unread message exists and when the unread message does not exist, that is, unread notification, or normal. Notify.

Now, the calling patterns of the unread notification drive signal and the normal notification drive signal output from the notification drive section 9 will be described with reference to the waveform diagrams of FIGS. 2, 3 and 4.

FIG. 2A is a waveform diagram illustrating a first calling pattern of an unread notification drive signal and a normal notification drive signal.

In the figure, the notification drive section 9 outputs the normal notification drive signal of the calling pattern shown in FIG. 2A to the notification section 10 when the normal notification generation signal "10" output from the message control section 6 is input. On the other hand, the notification drive unit 9 outputs the unread notification generation signal “0” output from the message control unit 6.
When "1" is input, the unread notification drive signal having the calling pattern shown in FIG. 2B is output to the notification unit 10. Here,
Comparing FIGS. A and B, the length of one cycle of the calling pattern is the same, but the patterns of one cycle are different. The notification drive unit 9 outputs the illustrated normal notification drive signal and the unread notification drive signal to the notification unit 10, and when the notification unit 10 is driven, the sound generated by the notification unit 10 is different from the calling pattern in FIG. Since the same notification sound as the above is output, the carrier can recognize the presence or absence of the unread message. That is, when the notification drive unit 9 outputs the normal notification drive signal shown in FIG. A, the notification sound generated by the notification unit 10 becomes a discontinuous sound, while the notification drive unit 9 outputs the unread data shown in FIG. When the notification drive signal is output, the notification sound generated by the notification unit 10 becomes a continuous sound.

FIG. 3 is a waveform diagram for explaining the second calling pattern of the unread notification drive signal and the normal notification drive signal.

In the figure, when the notification drive unit 9 inputs the normal notification generation signal "10" output from the message control unit 6, it outputs the normal notification drive signal of the calling pattern shown in FIG. 3A to the notification unit 10. On the other hand, the notification drive unit 9 outputs the unread notification generation signal “0” output from the message control unit 6.
When "1" is input, the unread notification drive signal having the calling pattern shown in FIG. 3B is output to the notification unit 10. Here,
Comparing FIGS. A and B, they are different in the length of one cycle of the calling pattern. That is, the notification drive unit 9
However, when the normal notification drive signal shown in FIG. A is output, the notification sound of a fixed pattern is output at the cycle of the notification sound generated by the notification unit 10, that is, at a long time interval, while the notification drive unit 9 outputs the notification sound shown in FIG. When the unread notification drive signal shown in is output, the notification sound of a fixed pattern is output at a cycle of the notification sound generated by the notification unit 10, that is, at a short time interval.

FIG. 4 is a waveform diagram for explaining a third calling pattern of the unread notification drive signal and the general notification drive signal.

In the figure, when the notification drive unit 9 inputs the normal notification generation signal "10" output from the message control unit 6, the notification drive unit 9 outputs the normal notification drive signal having the calling pattern shown in FIG. 4A. On the other hand, the notification drive unit 9 outputs the unread notification generation signal “0” output from the message control unit 6.
When "1" is input, the unread notification drive signal of the calling pattern shown in FIG. 4B is output to the notification unit 10. Here,
Comparing Figures A and B, the two have the same length of one cycle but differ in the frequency of one cycle. That is,
When the notification drive unit 9 outputs the normal notification drive signal shown in FIG. A, the notification sound generated by the notification unit 10 is output as a voice having a relatively slow rhythm, while the notification drive unit 9 outputs the notification sound shown in FIG. When the unread notification drive signal shown in is output, the notification sound generated by the notification unit 10 is output as a voice having a relatively fast rhythm.

In this embodiment, the notification unit 10
In the above description, a speaker is used and the notification by sound is described as an example. However, the notification unit other than the speaker may be configured by a vibrator or an LED.

When a vibrator is used in the notification unit of the radio selective calling receiver, the calling pattern in which the unread notification drive signal output from the notification drive unit 9 and the normal notification drive signal differ is generated by the notification unit 10. It is output as it is as the difference in vibration.

Further, the LE in the notification section of the radio selective calling receiver is used.
Even when D is adopted, the calling pattern in which the unread notification drive signal output from the notification drive unit 9 and the normal notification drive signal are different is output as it is as a difference in blinking of light generated by the notification unit 10.

Next, the operation of the radio selective calling receiver with the unread message notifying function according to the present invention shown in FIG. 1 will be described with reference to FIG. In addition, after the antenna 1 receives the radio signal from the radio base station, the decoder 3
The operation up to the output of the coincidence signal has been described in the description of FIG.

When the control unit 5 inputs the ID coincidence signal and the digitized demodulated signal (START), the control unit 5 searches the message memory 8 for the presence of an unread message. STEP 1). Control unit 5
However, when the unread message is detected from the message storage unit 8, the notification unit 10 performs control for performing the unread notification (STEP 2). Under the control of the unread notification of the control unit 5, the notification driving unit 9 drives the notification unit 10 to perform the unread notification. On the other hand, in STEP 1, if the control unit 5 does not detect the unread message from the message storage unit 8, the notification unit 10 performs control for performing normal notification (STEP 3). Under the control of the normal notification of the control unit 5, the notification drive unit 9 drives the notification unit 10 to perform the normal notification. After controlling the notification of the notification unit 10, the control unit 5 monitors whether or not the switch 11 is pressed (STEP 4). When the wearer notices that he is calling and presses the switch 11, the control unit 5
A notification stop signal is output (STEP 5). This control unit 5
In response to the notification stop signal output by, the notification drive unit 9 stops the notification of the notification unit 10. When the control unit 5 outputs the notification stop signal, the control unit 5 outputs the message included in the digitized demodulated signal to the display drive unit 12. Upon receiving the message output by the control unit 5, the display drive unit 12 causes the display unit 1 to
A message is displayed on 3 (STEP 6). Control unit 5
Outputs the message to the display drive unit 12, outputs the message to the message memory 8 and stores the message as a read message (STEP
7) End the operation (END). On the other hand, STEP
In monitoring whether or not the switch 11 of the control unit 5 is pressed in No. 4, when the wearer does not notice that the caller himself is being called and does not press the switch, a timer provided inside the control unit 5 measures time. After a lapse of a certain time (STEP 8), the control unit 5 outputs a notification stop signal (STEP 9). In response to the notification stop signal output by the control unit 5, the notification drive unit 9 stops the notification of the notification unit 10. When the control unit 5 outputs the notification stop signal, the control unit 5 outputs the message included in the digitized demodulated signal to the message memory 8, stores the message as an unread message (STEP 10), and ends the operation (END).

Further, regarding the details of the operation of the control unit 5,
The operations of the message control unit 6 and the switch detection unit 7 that form the control unit 5 will be described with reference to FIGS.

FIG. 6 is a flow chart for explaining the operation of the message controller 6.

First, the message control unit 6 causes the decoder 3
The ID coincidence signal output by is input (START). When the message control unit 6 receives the ID match signal, the message memory 6 searches the message memory 8 to determine whether or not an unread message is stored, by detecting a message whose first bit is 1 (STEP).
11). When the message control unit 6 detects a message having a leading bit of 1 from the message storage unit 8, it sends an unread notification generation signal of a digital signal "01" which is a 2-bit identification signal (STEP 12). When the message control unit 6 does not detect the message having the first bit of 1 from the message storage unit 8, the normal notification generation signal of the digital signal "10" which is the 2-bit identification signal is transmitted (STEP 13). The message control unit 6 waits for the input of the switch detection signal after transmitting the normal notification generation signal with the unread notification generation signal (STEP 14). When the message control unit 6 receives the switch detection signal, it outputs a notification stop signal of the digital signal "11" which is a 2-bit identification signal (STEP 15). Further, when the message control unit 6 outputs the notification stop signal, the message control unit 6 outputs a message included in the digitized demodulated signal to the display drive unit 12 (STEP 16). When the message control unit 6 outputs the message to the display drive unit 12, the message control unit 6 adds 0 to the first bit of the message equivalent to the message output to the display drive unit 12 and determines that the message has been read (STEP 17). , Message control unit 6
But this read message is stored in the message memory 8
(STEP 18) to end the operation (EN
D). On the other hand, the message control unit 6 in STEP 14
When the switch detection signal is not input and the time-up signal is input instead of waiting for the switch detection signal of (STEP 19), the notification stop signal of the digital signal “11” which is a 2-bit identification signal is output (STEP 2).
0). Further, when the message control unit 6 outputs the notification stop signal, the message control unit 6 adds 1 to the first bit of the message included in the digitized demodulated signal to make it an unread message (STEP 21), and the message control unit 6 causes the message to be unread. The read message is output to the message memory 8 (STEP 22) and the operation is ended (END).

FIG. 7 is a flow chart for explaining the operation of the switch detector 7. First, the switch detector 7
When the unread notification generation signal or the normal notification generation signal output from the message memory control unit 6 is input, a timer provided inside the switch detection unit 7 is started (START). When the switch detection unit 7 starts the timer, the switch detection unit 7 monitors whether or not the switch 11 is pressed, and waits for the switch 11 to be pressed (STEP 23). When the switch detection unit 7 detects the pressing of the switch 11,
The switch detection unit 7 outputs a switch detection signal to the message control unit 6 (STEP 24) and ends the operation (END). On the other hand, while waiting for the pressing of the switch 11 of the switch detector 7 in STEP 23, the switch 1
1 is not pressed and a certain period of time has passed, the switch detection unit 7
When the time measured by the timer provided inside the timer counts up (STEP 25), the switch detector 7 outputs a time-up signal to the message memory controller 6 (STEP 25).
26) and end the operation (END).

[0040]

As described above, the radio selective calling receiver with the unread message notification function according to the present invention is
Using the call notification that the presence of the unread message exists when the radio selective call receiver itself is called, when the unread message exists and when it does not exist,
Since the call notification is performed in different forms, it is possible to prevent the troublesomeness of checking the presence of an unread message by operating a switch or the like as in the conventional case. Further, since it is possible to automatically know the presence or absence of the unread message at each call notification, there is a problem that the unread message is erased due to the limit of the storage capacity of the storage means for storing the unread message. The probability can be significantly reduced, and unread messages can be confirmed without fail.

Further, the radio selective calling receiver with the unread message notifying function according to the present invention uses the timer provided inside the microprocessor to measure the time without adding any new time measuring means. Since there is no need to increase the number of circuit components or to notify the presence of an unread message at a fixed time interval by sound, even if the carrier is present at the meeting, the notification sound disturbs the meeting. The probability that such a problem will occur can be significantly reduced.
