DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio paging receiver, and more particularly to a paging signal received from a base station, displaying the message data and the reception date contained in the paging signal and storing them in a memory. The present invention relates to a radio selective calling receiver.

[0002]

2. Description of the Related Art Conventionally, a radio selective call receiver of this type displays a received message, stores it in a memory, and can protect, delete, and read the message. An example of a conventional radio selective call receiver is disclosed in Japanese Patent Application Laid-Open No. 1-270421 ("Selective call receiver"). This conventional selective call receiver includes a receiving unit, a memory all erasing unit, a message display control unit, a storage unit, and an input unit. When the clear mode is selected by the input means during the message display by the message display control means, the messages stored in the storage means and not set to be stored are erased by the all memory erasing means.

An example of another conventional selective call receiver is disclosed in Japanese Patent Application Laid-Open No. 3-147431 ("Selective call receiver and message erasing method"). The conventional selective call receiver includes a receiving unit, an erasure information designating unit, a message erasing unit, a timing unit, a display unit,
It comprises storage means and input means. And
The message deletion time is input and designated by the deletion information designation means, and the message stored in the storage means is deleted by the message deletion means in response to the time counted by the clock means. In addition, the message stored in the storage unit is deleted in response to the time corresponding to the message storage time set by the deletion information designating unit being measured from the message reception time by the timer unit.

[0004]

However, these conventional techniques have the following problems.

[0005] The first problem is that message protection, deletion, and the like cannot be performed partially (by specifying a range).
The reason is that message protection, deletion, etc. are performed for each message by a switch operation during message display, or all message deletion is selected and deleted by a switch operation during message display.

A second problem is that important messages are also deleted from the memory when a set time elapses or a predetermined time elapses. The reason is that important messages are not protected by the holder, new messages are received, important messages have passed the specified time even if the memory is not insufficient, or a certain period of time This is because when the time has elapsed, the data is erased from the memory.

A third problem is that when a normal message is read, the message is read in descending or ascending order, so that only the desired message cannot be read.

Accordingly, the present invention sets a reception date, a start date, and an end date of a message stored in a memory to protect, delete, or display a message received within a date range. That is the task.

[0009]

According to another aspect of the present invention, there is provided a radio selective call receiver comprising: an input unit for inputting range selection information; and a storage unit for storing the range selection information. A paging signal sent from the base station is received, and within a selected range, a message included in the paging signal and a reception date are displayed and stored in another storage unit.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a radio selective calling receiver according to the present invention. As shown in FIG. 1, the radio selective call receiver according to the present invention includes an antenna 1 for receiving its own call signal sent from a base station, a radio unit 2, a control unit 3 operated by program control, and message reading. Input section 4 of the switch for inputting data, protection / deletion, menu selection, etc.
And a display unit 5 for displaying a received call signal message and information such as a menu, a notification unit 6 for giving a notification sound when a call signal is received, and a storage unit 7 for storing message information. , A storage unit 8 for storing its own ID code, range setting information, and the like, and a clock unit 9 for clocking the reception date and time. The control unit 3 includes a protection control unit 31, an erasure control unit 32, a range determination unit 33, and a range setting unit 34.

The protection control means 31 adds a protection attribute if the message stored in the memory is within the set range.

The erasure control means 32 erases the message stored in the memory if the received date is within the range.

The range judging means 33 sets a flag indicating the range referred to by the protection control means 31 and the erasure control means 32 in the message attribute information based on the reception date information of the message stored in the memory. I do.

The range setting means 34 includes the range determination means 3
The start date and the end date referred to in 3 are set by the input unit (switch), and the start date and the end date are stored in the memory. In addition, protection, deletion,
By selecting the message reading, the operation (protection / deletion / reading) for the message in the date range set above is controlled.

As described above, the range is set by designating the start date and the end date, and the ranges are compared with reference to the reception date of the message stored in the memory. By setting the attribute information, partial protection, erasure, and reading are enabled.

Next, the operation of the control unit 3 will be described in detail.

The protection control means 31 includes a storage unit (memory) 7
Then, it is determined whether the in-range flag is set in the message information, and if it is set, information indicating protection is set in the message information. If it is not within the range, no protection information is set.

The erasure control means 32 includes a storage unit (memory) 7
From the storage unit (memory) 7 if the in-range flag is set in the message, and if so, it is further determined whether the message is a protected message. to erase. If it is not within the range, the message is not deleted from the storage unit (memory) 7.

The range determining means 33 includes a storage unit (memory) 8
, Read out the range setting information (start date and end date), read out the message information from the storage unit (memory) 7 and compare the received date of the message with the range setting information. If the value is outside the range, the flag within the range is set to OFF, and the next message information is read to determine the range. This operation is repeated for the number of stored messages.

The range setting means 34 stores the start date and the end date inputted by inputting the input of the range setting information (start date and end date) referred to by the range judgment means 33 into a storage unit (memory) 8. To store. Also, protect, erase,
When the read mode is specified by the input from the input 4, protection, erasure, and read processing are performed.

Next, the overall operation of the radio selective call receiver of the present invention will be described with reference to the flowcharts of FIGS.

As shown in FIG. 2, first, when the range setting means is selected by the input of the input unit 4, the start "date" of the range is set.
Is displayed on the display unit 5 (step S102). Next, if the input of the input unit 4 is other than the confirmation switch, the start “date” is selected (step S103). Input unit 4
It is determined whether the input is a confirmation switch, and if not, the start “date” is displayed again (step S1).
04). When the input of the input unit 4 is a decision switch,
The start “date” is temporarily determined, and the display of the end “date” is displayed on the display unit 5 (step S105). Next, the input unit 4
If the input is other than the confirmation switch, the end "date" is selected (step S106). It is determined whether the input of the input unit 4 is a decision switch, and if not, the end “date” is displayed again (step S107). If the input of the input unit 4 is a determination switch, the start “date” and the end “date” are determined, and the start “date” and the end “date” are stored in the storage unit (memory) 8 (step S10).
8). Next, the range determination means is activated and the storage unit (memory) 7
Is determined (step S109).

FIG. 3 is a flowchart for explaining the processing by the range determining means in step S109. As shown in FIG. 3, first, the message information of the message stored in the storage unit (memory) 7 is read (step S202), and the reception date information is extracted (step S203). It is determined whether the extracted reception date information is received within the range of the start “date” and the end “date” stored in the storage unit (memory) 8 (step S20).
4). If the received date falls within the range, the in-range flag is set to ON in the message information of the message (step S205). If the received date is not within the range, the in-range flag is set to OFF in the message information of the message (step S208). Thereafter, the message counter is incremented (step S206), and it is determined whether or not the next message is stored in the storage unit (memory) 7 (step S207).
Steps S208 to S208 are repeated until there are no more messages. If there are no more messages, the process ends (step S209).

Referring again to FIG. 2, in step 110 following step 100, a mode selection of whether to protect, delete, read the message, or end the setting is displayed on the display unit 5 (step S11).
0), it is determined whether the input of the input unit 4 is protected, erased, read, or completed (step S111).

FIG. 4 is a flowchart for explaining the processing subsequent to step S111. Step S111
As a result of the determination in the above, when the setting is other than the end, and when the protection is selected (step S121), the protection control means (S128) is performed.

FIG. 5 is a flowchart for explaining the processing by the protection control means shown in step S128. As shown in FIG. 5, first, the message information of the message stored in the storage unit (memory) 7 is read (step S302). The in-range flag is determined (step S
303), if the in-range flag is set to OFF,
Proceed to step S305. If the in-range flag is set to ON, an attribute indicating that the message is a protected message is added to the message information of the message (step S304). Next, the message counter is incremented (step S305), and it is determined whether the next message is stored in the storage unit (memory) 7 (step S306). If the next message is stored in the storage unit (memory) 7, steps S302 to S305 are repeated until the end of the message. If the message has been determined to the end, the process ends (step S307).

FIG. 6 is a flowchart for explaining the processing in the erasure control means shown in step S120. As shown in FIG. 6, first, the message information of the message stored in the storage unit (memory) 7 is read (step S402). The in-range flag is determined (step S403). If the in-range flag is set to OFF, the process proceeds to step S406. If the in-range flag is set to ON, the protection attribute of the message is determined (step S404). If the message is a protected message, the process proceeds to step S406. If the message is not a protected message, the message is deleted from the storage unit (memory) 7 (step S405). Next, the message counter is incremented (step S
406), it is determined whether the next message is stored in the storage unit (memory) 7 (step S407). If the next message is stored in the storage unit (memory) 7,
Steps S402 to S407 are repeated until the end of the message. If the determination is made up to the end of the message, the process ends (step S408).

Referring again to FIG. 4, when the reading is selected (step S123), the message information is read from the storage unit (memory) 7 (step S12).
4) It is determined whether the in-range flag is set (ON) in the message (step S125), and the setting (ON)
If so, a message is displayed on the display unit 5 (step S126). If the in-range flag is not set (OFF) in step S125, the process proceeds to step S127. Next, it is determined whether the reading of the next message is selected by the input of the input unit 4 (step S127). If the next message is read, the message counter is incremented (step S13).
0), the process returns to step S124 to read out the message information, and the process is repeated. If it is not the reading of the next message, the process ends as shown in FIG.
112).

Also, as shown in FIG. 2, step S110
If the setting has been completed, the process ends.

Next, another embodiment of the present invention will be described with reference to the drawings. Here, the message number is used as the range selection information instead of the date.

As the range setting means of FIG. 7, the start message number is displayed on the display unit 5 (step S502), and then the start message number is selected by input from the input unit 4 (step S503). If the input from the input unit 4 is the confirmation switch, the end message number is displayed on the display unit 5 (step S505). Next, an end message number is selected by input from the input unit 4 (step S50).
6). When the input of the input unit 4 is a decision switch, the start message number and the end message number are stored in the storage unit (memory) 8.

Steps S504 and S5 in FIGS.
07, and the operations of the range setting means 34, the protection control means 31, and the erasure control means 32 shown in S509-S529 are the same as the operations shown in FIGS.

As the range judging means in FIG. 9, message information is read from the storage unit (memory) 7 (step S60).
2), a message number is extracted from the message information (step S603). Next, the start message number and the end message number stored in the storage unit (memory) 8 are read and compared with the extracted message numbers (step S604). If the comparison result is within the range, the in-range flag is set ON (step S605), and is set OFF outside the range (step S608). The message counter is incremented to compare the next message (step S606), and the messages are sequentially determined.

Note that steps S602 and S604 in FIG.
-S605 and S607-S608, the operation of the range determination means 33 is the same as the operation shown in FIG.
Description is omitted.

[0036]

According to the present invention described above, a first effect resides in that protection, deletion, and reading of a message in an arbitrarily designated range can be performed. The reason is that when protecting, erasing, or reading a message, the start date and end date are set by the range setting means so that only the message when the range flag is set to ON is referred to by referring to the range flag. So that it can be set by the input of the input means,
When the received date is within the range, the in-range flag is set to ON if the received date is within the range by comparing the received date with the start date and the end date by the range determination means. If the value is out of the range, the in-range flag is set to OFF.

The second effect is that only messages within the range set by the holder are erased, so there is no need to protect messages that are not desired to be erased when all messages are erased, and unnecessary messages are erased at once. What you can do.
