JPH04273727A - Radio selective call receiver with unconfirmed message information function - Google Patents

Abstract

PURPOSE:To offer a radio selective call receiver which informs the fact that a reception message estimated as the one not being confirmed by a user is present periodically. CONSTITUTION:When call information by the flash of a LED 9, etc.. by the reception of an address signal that coincides with its own address and display by the LCD 13 of the reception message are performed, such display is automatically reset. A CPU 6 defines a message received this time and stored in a RAM 5 as an unconfirmed message. The CPU 6 issues the information representing the presence of the unconfirmed message in a type distinguishable from selective information by a method of flashing the LED 9, etc., at every prescribed time by a timer 16 while the unconfirmed message is being stored in the RAM 5. When the readout operation of the message is performed at a switch part 14, and the unconfirmed message stored in the RAM 5 is re-displayed on the LCD 13, and also, a confirming operation is performed, the CPU 6 defines the message as a confirmed message.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a wireless selective calling receiver, and in particular, an unconfirmed message that periodically notifies the user when there is a received message that is presumed to have not been confirmed by the user. This invention relates to a wireless selective calling receiver with a notification function.

0002

2. Description of the Related Art Currently, a wireless selective calling receiver with a message display function is in practical use as a type of wireless selective calling receiver. This wireless selective call receiver with a message display function notifies the user of the call in the form of blinking an LED, ringing a speaker, or vibrating a vibrator by receiving an address signal that matches its own address, and also notifies the user of a message that is subsequently received. is stored in the memory and displayed on a display such as an LCD. Note that if a confirmation operation is performed during call notification and message display, call notification and message display will stop. This is called a manual reset. Further, if no confirmation operation is performed within a predetermined time, the call notification and message display are also stopped for reasons such as saving power. This is called autoreset.

[0003] One reason why received messages are stored in memory is that the user cannot always recognize the call notification, so the message displayed on the display at the same time as the call notification cannot be confirmed. This is to store it in memory so that it can be displayed again later. For this reason, this type of wireless selective calling receiver is usually designed so that the message stored in the memory can be redisplayed on the display by performing a message reading operation.

0004

In the conventional radio selective calling receiver, if an unconfirmed message has been received, it can be confirmed by performing the message reading operation as described above. However, unless a message read operation is performed, it is not known whether or not there are unconfirmed messages. For this reason, there is always the fear that there may be unconfirmed messages, and it is necessary to perform message reading operations frequently.

[0005] Note that if an auto-reset is performed at the time of a call notification, it can be assumed that the user has not confirmed the message displayed at the same time, so the auto-reset received message is treated as an unconfirmed message and a manual reset is performed. A radio selective calling receiver is also reported that treats each received message as a confirmed message, does not issue a call notification when a confirmed message is displayed by a subsequent message read operation, and performs a call notification again when an unconfirmed message is displayed. has been done. According to such a wireless selective call receiver, it is possible to distinguish between unconfirmed messages and confirmed messages, but it is different from the above-mentioned wireless method in that it is not possible to know whether or not there are unconfirmed messages unless a message reading operation is performed. There is nothing different from a selective call receiver.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wireless selective calling receiver with an unconfirmed message reporting function that proactively notifies a user if there is a received message that is assumed to have not yet been confirmed. It's about doing.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the wireless selective calling receiver with an unconfirmed message reporting function of the present invention notifies the caller by receiving an address signal that matches its own address. In a wireless selective calling receiver that simultaneously displays a received message on a display and stores it in a memory, and redisplays the message stored in the memory on the display in response to a later message read operation, the By automatically resetting the notification and message display, there is a means for making the currently received message stored in the memory an unconfirmed message, and a means for making the unconfirmed message stored in the memory at predetermined intervals. and a means for reporting the presence of an unconfirmed message.

[0008] Furthermore, a structure is adopted in which the method of driving the annunciator used for call notification is different from that used for call notification, so that the unconfirmed message notification is generated from the annunciator.

[0009]

[Operation] In the wireless selective calling receiver with an unconfirmed message reporting function of the present invention, when an address signal that matches the own address is received and the calling notification and the received message are displayed, the predetermined If an auto-reset is performed because no confirmation operation was performed within the specified time, the currently received message will be marked as an unconfirmed message, and while such an unconfirmed message is stored in memory, an unconfirmed message will be sent at a predetermined time interval. An unconfirmed message notification is generated to the effect that it exists.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

Referring to FIG. 1, the wireless selective calling receiver with an unconfirmed message reporting function of this embodiment receives, for example, FSK (Frequency) signals sent from a transmitting station or the like.
An antenna 1 that receives a radio signal modulated by Shift Keying), a receiver 2 that amplifies and demodulates the received radio signal, a decoder 3 that detects its own address in the received signal, and the radio selective call receiver. The control unit 8 performs the main control of the
D9, speaker 10, vibrator 11, alert driver 12 that drives these, L that displays messages, etc.
It includes a CD 13, a switch section 14, and an ID-ROM 15 for initializing the wireless selective call receiver.

[0012] The control unit 8 has a P-
ROM4, RAM5 for storing received messages, and CP
U6, LCD driver 7 for LCD13, and timer 1
6.

The switch section 14 is a section used by the user to perform confirmation operations, message reading operations, etc., and includes a plurality of switches.

FIG. 2 is a flowchart showing an example of processing performed after power is turned on of the wireless selective calling receiver of FIG.
FIG. 3 is a flowchart showing an example of the process performed when an interrupt is generated by the timer 16, FIG. 4 is a flowchart showing an example of the process when a message read operation is performed, and FIG. 5 is the sound and blinking pattern adopted in this embodiment. It is a time chart showing an example. The operation of the wireless selective calling receiver with an unconfirmed message reporting function according to this embodiment will be described below with reference to the figures.

When the power is turned on, the CPU 6 in the control section 8 of the wireless selective calling receiver shown in FIG. 1 starts the process shown in FIG. First, the CPU 6 reads initial state information from the ID-ROM 15 and initializes each part (step S1). The ID-ROM 15 stores in advance the address (ID number) assigned to the wireless selective call receiver and re-notification time information indicating the time interval at which unconfirmed message notifications are to be made. As part of the initial setting in step S1, notification of the address to the decoder 3, setting of re-notification time information to the timer 16, etc. are performed. Note that writing of the above information into the ID-ROM 15 is performed on the service station side of the wireless selective call receiver. In addition, the re-notification times are 5 minutes, 10 minutes, and 15 minutes.
Time such as minutes is used.

The timer 16 is a timer that times out every re-notification time set by the CPU 6 and interrupts the CPU 6, and the CPU 6 performs the processing shown in FIG. 3 at the time of the interrupt. Processing at the time of this interrupt will be described later.

After that, the CPU 6 waits for the address and message to be sent from the decoder 3 (step S2).
).

When a radio signal is received by the antenna 1 in FIG. 1, the signal is amplified and demodulated in the receiving section 2 and inputted to the decoder 3, and the decoder 3 detects an address matching its own address in the received signal. Checks whether the signal is included, and if so, notifies the control unit 8 of the address;
Furthermore, it detects a message following the address signal and sends it to the control section 8.

When the CPU 6 detects that the address and message have been sent from the decoder 3 in step S2 (YES in step S2), it stores the received address and message as a set in the RAM 5 (step S2).
3), and displays the received message on the LCD 13 using the LCD driver 7, and the decoder 3
The call notification corresponding to the current reception address is started (step S4). In response to this, the decoder 3 activates the alert driver 12 and issues a call notification by one or a combination of blinking the LED 9, sounding the speaker 10, and vibration of the vibrator 11.

For example, when making a call notification using the speaker 10 and the LED 9, the following diagrams are displayed depending on the type of the received own address (from the first address to the sixth address) and the type of call (from A to D). Speakers 10 and L with different sound and flashing patterns as shown in Figure 5.
When the ED 9 is driven, a call notification is performed using a corresponding pattern of sound and flashing.

After starting the call notification and message display as described above, the CPU 6 determines whether or not a confirmation operation has been performed on the switch unit 14 within a predetermined period of time (steps S5, S6). If the confirmation operation is performed within the time (YES in step S5), the decoder 3 is caused to stop the call notification by the LED 9, the speaker 10, etc., and the display of the received message by the LCD 13 is also stopped (step S7).

On the other hand, if the confirmation operation is not performed after a certain period of time has elapsed (YES in step S6), the call notification and message display are stopped as in step S7 (step S8), and then the current The received message is determined to be an unconfirmed message (step S9). Specifically, a predetermined code indicating that the message is an unconfirmed message is added to the current address and received message pair stored in the RAM 5, for example.

After that, the CPU 6 returns to step S2.

On the other hand, as mentioned above, the timer 16
The CPU 6 is interrupted at every re-notification time set from 6, and the CPU 6 executes the process shown in FIG. 3 at each interrupt.

First, the CPU 6 determines whether or not a message to which a predetermined code indicating that it is an unconfirmed message is stored in the RAM 5 (step 21). If such a message does not exist (NO in step S21), the current interrupt processing ends.

On the other hand, if a message with a predetermined code indicating that it is an unconfirmed message exists (YES in step S21), the decoder 3 is instructed to generate an unconfirmed message report (step S22). In response, the decoder 3 activates the alert driver 12 with a sound and flashing pattern different from the sound and flashing pattern employed in the call notification, that is, the unconfirmed message reporting pattern shown in FIG. As a result, the person carrying the receiver is notified of the existence of an unconfirmed message in a form that can be distinguished from a call notification.

[0027] As for the form of unconfirmed message notification by the vibrator 11 which generates vibration by a motor using an eccentric core, for example, the vibrator 11 is operated intermittently to distinguish it from continuous operation at the time of call notification.

If a message reading operation is performed on the switch section 14 of FIG. 1 while the unconfirmed message is being reported as described above, the CPU 6 immediately ends the process of FIG. 3 and starts the process of FIG. Execute. Note that the process shown in FIG. 4 is also executed when a message read operation is performed during any period when an unconfirmed message notification is not performed.

First, the CPU 6 reads out one address and message pair stored in the RAM 5 (step S31). If there is a set that can be read out (step S3
2: NO), it is determined whether a predetermined code indicating that the message is an unconfirmed message is added thereto, that is, whether the message read this time is an unconfirmed message (step S33).

If the read message is not an unconfirmed message but a confirmed message, the message is simply displayed on the LCD 13 using the LCD driver 7, and no call notification is performed (step S35). On the other hand,
If the read message is an unconfirmed message (YES in step S33), the decoder 3 starts the call notification corresponding to the current address (step S34).
At the same time, the message is displayed on the LCD 13 using the LCD driver 7 (step S35). The decoder 3 uses the alert driver 1 in the pattern shown in Figure 5.
2 is activated, and a call notification is made by blinking the LED 9, ringing the speaker 10, etc.

Next, the CPU 6 determines whether or not a confirmation operation has been performed on the switch unit 14 and whether or not a message reading operation has been performed again (steps S36, S37), and if the confirmation operation has been performed this time. If the displayed message is an unconfirmed message (YES in step S38), R
The predetermined code corresponding to the message stored in AM5 is deleted, the message is made a confirmed message (step S39), and the process returns to step S31 to process the next message. If it is not an unconfirmed message (step S
38), the process skips step S39 and returns to step S31 to process the next message.

[0032] Furthermore, if the message reading operation is performed without the confirmation operation (YES in step S37).
, skipping steps S38 and S39 and proceeding to step S3
Return to step 1 and process the next message. Therefore, even if an unconfirmed message is redisplayed, if no confirmation operation is performed, the message remains an unconfirmed message.

[0033]

[Effects of the Invention] As explained above, the wireless selective call receiver with the unconfirmed message reporting function of the present invention is capable of automatically resetting the receiver because the confirmation operation was not performed within a predetermined time at the time of call notification. Received messages are treated as unconfirmed messages, and until such unconfirmed messages are redisplayed by a message read operation and a confirmation operation is performed, a notification that an unconfirmed message exists is issued at a predetermined time interval, so that users can can know whether or not an unconfirmed message exists without performing any active operation. Therefore, it is possible to eliminate the anxiety that ``an unconfirmed message might exist'' and relieve the user from the task of frequently performing message reading operations for confirmation.

Furthermore, by generating an unconfirmed message report by driving the annunciator used for the call notification in a different manner from that used for the call notification, the annunciator can be used for both the call notification and the unconfirmed message notification.
