DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling receiver, and more particularly to a radio selective calling receiver for storing and displaying a received message and deleting a message containing an error.

[0002]

2. Description of the Related Art A radio selective call receiver stores a received message in a memory and displays a message selected from a group of stored messages on a display.
Since the capacity of the message storage memory is limited, a newly received message cannot be stored unless the stored message is deleted according to some criteria. In a conventional radio selective calling receiver, a message stored in a memory is deleted by a receiver performing a predetermined switch operation.

[0003] For this reason, receiving without burdening the receiver,
As a technique for automatically deleting stored messages, a radio selective call receiver that compares a message reception time with a current time and performs automatic deletion based on the time difference has been proposed (see Japanese Patent Application Laid-Open No. 04-220026). ).

[0004]

In the above-mentioned conventional radio selective call receiver, when a message which is particularly unnecessary for the receiver, such as an erroneous message, is received, the message receiver deletes the message in advance. Required many switch operations. Therefore, if unnecessary message deletion is neglected by this troublesome switch operation, the limited message storage memory cannot be used effectively, and important messages are discarded due to unnecessary messages. Could have occurred.

In the case of a radio selective calling receiver that automatically deletes a message based on the time difference between the message reception time and the current time, troublesome switch operations for the recipient are not required, but deletion is performed for each message. There was a problem that it was not possible to determine whether it was good or bad, and even a message necessary for the recipient was deleted.

As a technique for avoiding this problem and deleting only an erroneous message, when an erroneous message is received, the message is temporarily written to a memory, and when the next message is received, the message is deleted from the previous erroneous message. There has been proposed a radio selective call receiver which deletes an erroneous message by overwriting a received message (see JP-A-63-240139). However, in this radio selective calling receiver, the erroneous message may be deleted before the recipient confirms it, and the erroneous message is stored in the memory until the next message is received. Therefore, when the recipient feels that the message is unnecessary and tries to delete it, a complicated switch operation is imposed on the recipient.

[0007] It is an object of the present invention to provide a radio selective call receiver in which an erroneous message is automatically deleted, thereby effectively utilizing the storage capacity of a memory and improving operability and convenience for a receiver. Is to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the outline of the present invention will be described.
The radio selective calling receiver has an abnormal message detecting means for detecting a received message containing an error. It also has control means for controlling each means, message storage means for storing or deleting messages, and reporting means for reporting received messages. The abnormal message detection means is activated when the message reception notification operation by the notification means ends, and checks whether the received message notified via the control means contains an error. The message storage means deletes the received message in response to a request from the control means when it is determined by the inspection by the abnormal message detection means that the message contains an error.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, a radio selective calling receiver of the present example (first embodiment) includes a receiving unit 2 for demodulating a radio signal (a calling signal from a radio channel) received by an antenna 1.
An operation switch unit 3; a control unit 4 for controlling the entire receiver; an abnormal message detection unit 5 for detecting an erroneous received message; a message storage unit 6 for storing the received message; A notification unit 7 for notifying reception, a speaker 8 for notifying by sound at the time of notification,
A display unit 9 for displaying the received message.

Next, the operation of the radio selective calling receiver of this embodiment will be described.

The antenna 1 having received the radio signal notifies the receiving unit 2 of the fact. The receiving section 2 demodulates the notified radio signal and, when recognizing that it is a paging signal addressed to itself, cuts out the received message and accompanying information and
Notify.

The switch section 3 is a switch for setting the operation of the radio selective calling receiver, and the control section 4 performs various control operations according to the switch operation by the receiver. The abnormal message detection unit 5 is controlled by the control unit 4, checks whether or not the received message contains an error, and notifies the control unit 4 of the result. The message storage unit 6 stores or deletes the message requested from the control unit 4 and its accompanying information.

The notification unit 7 performs a notification operation in a method specified by a notification from the control unit 4. The speaker 8 outputs the signal from the notification unit 7 to the receiver as an audible sound. The display unit 9 converts the message data specified by the notification from the control unit 4 into display characters, and visually displays it to the recipient.

Next, the operation of the radio selective calling receiver of this embodiment will be described in detail with reference to the flowchart shown in FIG.

The control unit 4 receives the message reception notification from the receiving unit 2 (step 101), and stores the received message in the message storage unit 6 (step 102). Then, the received message is displayed on the display unit 9 (step 10).
3) The notification unit 7 is caused to perform a message reception notification operation (step 104).

Thereafter, the control unit 4 causes each unit to continue displaying and notifying the received message until the next event such as operation of the switch unit 3, timeout, reception of the next message, etc. occurs. If the message notification operation is terminated due to being performed, it is considered that the message recipient has confirmed the message (step 10).
5), the abnormal message detecting unit 5 checks whether the message contains an error (step 106). As a result, if it is determined that there is an error in the message, the received message is deleted from the message storage unit 6 (step 107).

If the message notification operation is terminated by an event other than the operation of the switch unit 3 in the process of step 105, the judgment of deleting the message is suspended, and there is an opportunity to notify the message again. If so, do so.

Next, another (second) embodiment of the present invention will be described with reference to the flowchart shown in FIG. The hardware configuration is the same as the configuration shown in FIG.

[0024]

[0025]

[0026]

The control unit 4 receives the message reception notification from the receiving unit 2 (step 301), and stores the received message in the message storage unit 6 (step 302). Then, the received message is displayed on the display unit 9 (step 30).
3) The notification unit 7 is caused to perform a message receiving notification operation (step 304).

Thereafter, the control unit 4 causes each unit to continue displaying and notifying the received message until the next event such as operation of the switch unit 3, timeout, reception of the next message, etc. occurs. If the message notification operation is terminated due to being performed, it is considered that the message recipient has confirmed the message (step 30).
5) The abnormal message detection unit 5 is checked whether the message contains an error (step 306). As a result, if it is determined that there is an error in the message, the display unit 9 is caused to display confirmation of deletion of the message (step 30).
7).

Then, the process waits for a response from the receiver (step 308), and when a response to permit deletion is returned via the switch unit 3, the received message is deleted from the message storage unit 6 (step 309). The message is not deleted when the response is other than the deletion permission.

If the message notification operation is terminated by an event other than the operation of the switch unit 3 in the process of step 305, the deletion judgment of the message is suspended, and there is an opportunity to notify the message again. If so, do so.

In any of the above embodiments, when a received message is displayed (steps 103 and 30).
In 3), whether or not the received message has an error can be displayed at the same time.

[0032]

As described above, according to the present invention, a message which would become unnecessary if a message such as an error message is read is automatically deleted when the receiver confirms it. Unnecessary messages can be deleted, which has the effect of reducing the burden on message recipients.

Further, by promoting the deletion of unnecessary messages, the memory space for storing the messages can be more effectively used.
