Description

The present invention relates to a paging receiver with a display function for receiving and displaying a message.

[Prior art and its problems]

Generally, a paging receiver with a message display function has multiple memory areas for storing received messages, and when a large number of messages are received and the above memory area becomes full, a new message is stored. In order to do so, messages are deleted in order from the oldest received time.

In addition to the normal call message, the paging receiver will receive a message from the paging service company informing that the contract deadline is approaching or that the call service will be terminated when the contract deadline expires. It may be sent.

However, in the conventional paging receiver, even if the contact message having the above contents is received, the contact message is kept until the person carrying the receiver reads and displays the contact message stored in the memory. There was an inconvenience that we could not know that we received it. Even if a contact message from a paging service company is received and stored, if a large number of call messages are received afterwards and the memory area becomes full, the contact message will be erased like a normal call message, and paging reception will be performed. There was also a problem that those messages might not be transmitted to the carrier of the machine.

[Purpose of device]

An object of the present invention is to provide a paging receiver with a display function that can effectively display a specific message such as the above-mentioned contact message.

[Key points of device]

The present invention is provided with a discriminating means for discriminating whether or not the received message is the specific message, and displaying the specific message discriminated by the discriminating means in the standby state. Further, the specific message is stored in a memory area different from that of the normal calling message, and when the large number of normal calling messages are subsequently received and the oldest messages are deleted in order, the specific message is not deleted. .

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a circuit configuration diagram of a paging receiver with a display function (hereinafter referred to as a paging receiver) according to an embodiment of the present invention.

In the figure, an antenna 1 is an antenna for receiving a radio signal transmitted from a radio base station, for example, a radio signal FSK-modulated by the POCSAG method, and the received signal is sent to the receiving unit 2. The receiving unit 2 detects, amplifies, and demodulates the received signal from the antenna 1, and converts it into serial digital data consisting of 0s and 1s. The decoder unit 3 is a circuit that analyzes the data output from the receiving unit 2 by the POCSAG method and determines whether the received address code (call number) matches the address code stored in the ID-ROM 4. is there. In this embodiment, two kinds of address codes are assigned to the ID-ROM 4, namely, an address code for individual calling assigned to each receiver and an address for receiving service information commonly assigned to a plurality of receivers. When the address code, that is, the calling number matches, the decoder unit 3 outputs a reception interrupt command to the CPU 6, and the address type information indicating which calling number matches, and the like. The received message information is output to CPU6. When the received calling number does not match its own calling number, the decoder unit 3 instructs the receiving unit 2 to terminate reception.

The key input section 5 includes a mode switch S ₁ for switching the time display mode, a normal call message display mode, a service information display mode, etc., and a read switch S for sequentially displaying the data stored in each mode. ₂ , equipped with a clear switch S ₃ for clearing the memory area specified by the read switch S ₂ , and a reset switch S ₄ for stopping the alarm sound and message display during reception, The operation signals of these switches are output to the CPU 6.

The CPU 6 is a central processing unit that executes a process of writing a message or the like received based on a reception interrupt command from the decoder unit 3 into the message memory 7 or reading a message or the like from the message memory 7, or a key process described later. Is.

The message memory 7 is a writable and readable memory that stores received messages and service information, and has a plurality of memory areas that store received data and various registers. The fixed phrase memory 8 is a ROM that stores various fixed phrases that can be used as messages and their abbreviated numbers. The character generator 9 is a ROM that stores character pattern data corresponding to the kana mode in the received message or the kana and kanji code of the fixed phrase memory 8.

The display buffer 10 is a memory for temporarily storing the character pattern data read from the character generator 9 under the control of the CPU 6, and the display data of the display buffer 10 is a display composed of a liquid crystal display or the like. The message is output to the unit 11 and the received message or the like is displayed. Further, the drive unit 12 is a circuit for driving the speaker 13 for a certain period of time when receiving a message to notify of an incoming call.

Next, FIG. 2 is a block diagram of the display unit 11 described above.
Is a number display section 11a that displays the reception numbers of messages given in the order of arrival, and a display that displays the call type (A or B) for identifying the calling party, etc. in a normal call using the individual call number. Part 11b and display unit 11c that displays the reception time
And a message display section 11d for displaying a message.

Further, FIG. 3 is a diagram showing the configuration of the message memory 7.

In the figure, a buffer register X is a register for temporarily storing newly received messages and the like. The mode counter M is a counter that stores a numerical value corresponding to the operation mode. M = 0 in the normal call message display mode, and M in the service information display mode.
= 1 is stored, and M = 2 is stored in the time display mode.

The clock register m ₀ is a register that stores time data including date, hour, minute, and second obtained by the CPU 6 sequentially measuring clock signals of a predetermined cycle. The memory area that stores the received data includes the memory area m ₁ that stores the contact message from the pager company, the multiple memory areas m ₂ to m ₂₁ that store the normal call message, and the contact message from the information service company. Memory area to store m
₂₂ and a plurality of memory areas m ₂₃ for storing service information
It consists of m ₄₂ and.

The pointer P is a pointer for designating one of the data stored in the memory areas of the above-mentioned clock registers m ₀ and m _{1 to} m _42. For example, when P = 0, the pointer P of the clock register m ₀ of address 0 is stored. If you specify the content and P = 1, the address 1
Contents of the memory area m ₁ are designated, and when P = 22, contents of the memory area m ₂₂ of address 22 are designated.

The display flag D is a flag that is set when the data read from the memory area is displayed on the display unit 11.
The alarm flag A is a flag that is set when a message is received. When the flag A is set, the speaker 13 sounds for 8 seconds, for example, to notify that there is an incoming call.
The timer register T is a register used for the above alarm notification time and time measurement for displaying a received message for a certain period of time.

The memory number counter N ₁ is a counter that stores the number of messages stored in the memory areas m _{2 to} m ₂₁ , and the memory number counter N ₂ is one of the service information stored in the memory areas m _{23 to} m ₄₂ . It is a counter that stores a number.

Further, the flag Y is a flag indicating whether or not the service information can be received, and is normally reset to "0" when a contract is signed. Is a flag that is set to ". When the flag Y is set to "1", the service information cannot be received thereafter.

Next, the operation of the embodiment having the above configuration will be described with reference to the flowcharts of FIGS. 4 to 6 (a) and (b).
Incidentally, FIG. 4 is a flow chart showing an outline of the whole processing of this embodiment, and FIGS. 5 and 6 (a) and (b) are flow charts showing the contents of the reception processing and the key processing.

The paging receiver is normally in the HALT state of step ST1 of FIG. 4, and when it receives its own calling number, it executes the reception processing of step ST2, and when any key is operated, it executes the key processing of step ST3. Run. Also, every time a clock signal of a predetermined cycle is applied, the clock / timer processing of step ST4 is executed. This time / timer process updates the contents of the time register m ₀ to obtain the current time data, and updates the contents of the timer register T only when the alarm flag A or the display flag D is set. When the content becomes 8 (8 seconds), the alarm sound is stopped, and when it becomes 30 (30 seconds), the mode counter M
Etc. to 0 to return to the reception standby state, thereby stopping the display of messages and the like.

Next, the contents of the reception process will be described with reference to FIG.

In this embodiment, the paging receiver uses two types of call numbers (addresses 1 and 2), that is, an individual call number assigned to each receiver and a common call number commonly assigned to a plurality of receivers. It is stored in 1D-ROM 4 (Fig. 1). When a contract for providing stock market information and the like is signed with the information service company, information is sent from the information service company via the paging system by the common call number, and the message memory 7 receives the information.
(FIG. 1).

When a call from the radio base station is detected, first, the type information of the address detected in step ST5 of FIG. 5 and the function bit information added to the address code are fetched, and subsequently, the message code word information is fetched in step ST6. , Is temporarily stored in the buffer register X together with the address type information and the like fetched in step ST5. Then, in step ST7, it is determined whether or not the message codeword is the end. If the message is the end, in the next step ST8, the reception unit 2 is instructed to terminate reception.

After the address type information, function bit information, and message information have been captured in this way,
Next, in step ST9, the address type information is the address 1
It is determined whether it is the individual call number of No. 2 or the common call number of Address 2. When the address is the individual call number, it is determined in step ST10 whether the value of the function bit is "00" and whether the received message is a message from the pager company.

In the present embodiment, of the four types of function codes that can be represented by the two function bits added to the POCSAG system address code, two types of code,
Used for the above-mentioned normal call type display (A, B) of 01, 10,
The remaining two types of codes, 00 and 11, are used as codes indicating that they are messages from the pager company and the information service company, respectively.

That is, when it is determined in step ST10 that the function code is “00”, the message is a message from the pager company, so the process proceeds to step ST11, and the message is stored in the memory area m ₁ of the message memory 7 described above. Memorize Further, display processing is executed in step ST12, and the received message from the pager company is displayed on the display unit 11.

If the message is not from the pager company in the determination in step ST10, the process proceeds to step ST13, and it is determined whether or not the message is from the service company by checking whether the function code is "11". When the message is from the service company with the code "11", it is determined in step ST14 whether or not there is a reception prohibition code in the received message. If there is a reception prohibition code, in step ST15 the reception prohibition flag Y
Is set to "1". If the reception prohibition code is not included at this time, it is determined in step ST16 whether or not there is a reception restart code, and if the reception restart code is included, "0" is set to the reception prohibition flag Y in step ST17. . After that, the received message from the service company is stored in the memory area m ₂₂ of the message memory 7.

In the processes of ST14 to ST17, when the contract deadline of the information providing service has expired, the reception prohibition code Y sent from the service company sets the reception prohibition flag Y to "1", and the service information cannot be received thereafter. Further, for example, when the contract is re-established after the contract expires, the reception prohibition flag Y is reset to "0" by the reception restart code sent from the information service company, and the service information can be received.

If it is not a message from the service company in the determination in step ST13, it means that a normal call message has been received, and the process proceeds to step ST19 to store the message. In this storage processing, the messages stored in the memory areas m _{2 to} m ₂₁ are sequentially shifted downward to empty the first memory area m ₂ , and the message received this time is stored in the empty memory area.

Then, in step ST20, the display flag D and the alarm flag A are set to "1". As a result, step ST21
Then, the received call message is displayed on the display unit 11, and at the next step ST22, the alarm sound for informing the incoming call is started. After that, in order to automatically stop the message display and sound after a predetermined time, step ST23.
Clear the timer register T with and start the time measurement for 30 seconds. As mentioned above, the automatic stop of the alarm and display is
In the timekeeping / timer processing, it is performed when the timer measures 8 seconds and 30 seconds.

On the other hand, when the address code received in the determination of the address type in step ST9 is the common calling number of address 2, the process proceeds to step ST24 and it is determined whether or not the reception inhibition flag Y is "1". When the reception prohibition flag Y = 0, it means that the information provided by the service company can be received, and the memory area of the message memory 7 in step ST25.
m ₂₃ ~m ₄₂ the service information is stored sequentially shifting down to, store the currently received information to the head of the memory areas m ₂₃ as a result free.

When a call from the radio base station is detected as described above, first, the normal call message and the service information are identified by the two kinds of address codes, and the message received from the four kinds of function codes is the normal call message. , Or a contact message from a pager company or an information service company, and based on the identification result, those messages and service information are stored in the corresponding memory areas.

Next, the contents of the key processing (ST4) in FIG. 4 will be specifically described with reference to FIGS. 6 (a) and 6 (b).

First, at step ST30 of FIG. 6 (a), that is operated to determine if S ₁ switch. Was operated
If the switch is the S ₁ switch, it is first determined whether the value of the mode counter M is 0 (ST31). If M = 0, 1 is added to the mode counter M to switch from the normal message display mode to the service information display mode, and the display flag D is set to "1" (SR32). Immediately after switching to this service information display mode, the pointer P
Set (ST33), and displays on the display unit 11 contact message from the service company, which is stored in the memory area m ₂₂ designated by the pointer P (ST34). After that, in order to display the read message for a certain period of time, step ST35
The clear start processing of is executed. In this clear start process, the timer register T is cleared to start counting time for 30 seconds, a message is displayed for 30 seconds, and then the display flag D is reset to end the display of the message. This clear start processing is executed subsequently to the display processing in each mode unless otherwise specified, and the message or service information is displayed for 30 seconds.

If M = 0 is not determined in the determination in step ST31, it is determined whether M = 1. If M = 1, it means that the S ₁ switch is operated in the service information display mode, 1 is added to the mode counter M to switch to the time display mode (M = 2), and the display flag D is set to “1”. Is set (ST37). When switching to this time display mode,
The pointer P is set to 0 (ST38), and the time data stored in the clock register of the memory area m ₀ designated by the pointer P is displayed on the display unit 11 (ST39). afterwards,
Execute the timer clear start processing (ST35) described above.
When 30 seconds have elapsed, the display flag D is reset and the time display is ended.

If M = 1 is not determined in the determination in step ST36, it means that the S ₁ switch is operated in the time display mode of M = 2, the mode counter M is set to “0”, and the display flag D is set to “0”. To switch to standby mode (ST
40). In this standby state, "1" is set to the pointer P (ST41), and a message from the pager company stored in the memory area m ₁ designated by the pointer P is displayed (ST42). If nothing is stored in the memory area m ₁ at this time, a blank is displayed.

If it is determined in step ST30 that the switch is not the S ₁ switch operation, then it is determined whether the S ₂ switch is operated (ST
43). If the operation is the S ₂ switch, it is first determined whether the mode counter M is “0” (ST44) and M = 0.
If so, it is further determined whether the display flag D is "1". At this time, if the display flag D is "1", the process directly proceeds to the next step ST47 to increment the pointer P, and if the display flag D is "0", the display flag D is set to "1" (ST46). , Increment the pointer P. Then, it is determined whether or not the updated pointer P value exceeds the message number register N ₁ +1 (ST4
8). If P ≦ N ₁ +1 then the message designated by the pointer P is read and displayed on the display unit 11 (ST49). That is, in the mode of M = 0, the S ₁ switch can be operated to sequentially display the normal call messages stored in the memory areas m _{2 to} m ₂₁ .

If P> N ₁ +1 at this time, it means that the value of the pointer P exceeds the number of stored messages, and the process proceeds to the above-mentioned step ST40 to reset the display flag D and switch to the standby state.

If M = 0 is not determined in the determination in step ST44, then it is determined whether or not M = 1 (ST50). If M = 1, pointer P
Is incremented (ST51), and the pointer P
It is determined whether the value of has exceeded the value of the memory number counter N ₂ +22 of the service information (ST52). If P ≦ N ₂ +2, the service information designated by the pointer P is read from the message memory 7 and displayed on the display unit 11 (ST53). That is, in the mode of M = 1, the service information sent from the information service company can be sequentially displayed by operating the S ₂ switch.

If P> N ₂ +22 at this time, it means that the value of the pointer P exceeds the number of stored service information,
The process proceeds to step ST40 and M = 0 is set, and the display register D is reset to switch to the standby state.

If M = 1 is not determined in the determination of step ST50, it means that the S ₂ switch is operated in the mode of M = 2, and the process proceeds to step ST54 to execute the time adjustment process. In this processing, the digits of the date, hours, minutes, and seconds are corrected according to the operation of the S ₂ switch and the S ₃ switch described later.

If it is determined in step ST43 that the switch is not the S ₂ switch operation, the process proceeds to step ST55 in FIG. 6B to determine whether the S ₃ switch is operated. If S ₃ switch that operated, the mode counter M to determine if "0" (ST56), and determines whether more or pointer P = 1 if M = 0 (ST57).

When the S ₃ switch is operated at P = 1, the message from the pager company stored in the memory area m ₁ is erased (ST58), and then the display process ST59 is executed.
Display the contents of the blank memory area.

If P> 1 at this time, it means that the deletion of the calling message stored in the memory area of m _{2 to} m ₂₁ is specified, and at that time, the contents of the memory specified by the pointer P are deleted. (ST60), and the message in the memory area in the subsequent stage is sequentially shifted upward (ST61). And
Since the deletion of one message is completed, the message number counter N ₁ is decremented (ST62). Further, the display process ST63 is executed to display a message newly designated by the pointer P as a result of the data shift.

If M = 0 is not determined in the determination in step ST56, it is determined whether M = 1 (ST64). When the S ₃ switch is operated in the mode of M = 1, it is further determined whether or not the pointer P = 22 (ST65). Memory area m when P = 22
When it is instructed to delete the contact message from the information service company stored in ₂₂ , the memory area is deleted (ST66), and the content of the blank memory area m ₂₂ after the deletion is displayed ( ST67).

If the value of the pointer P is P> 22, it means that the deletion of the service information stored in the memory areas m _{23 to} m ₄₂ is designated, and at that time, the memory area designated by the pointer P is erased. The contents are erased (ST68), and the data in the memory area in the subsequent stage is sequentially shifted upward (ST69). 1 more
Since the erasing of one service information is completed, the memory number counter N ₂ is decremented (ST70), and as a result of the data shift,
Information newly designated by the pointer P is displayed (ST7
1).

That is, in the modes of M = 0 and M = 1, after operating the S ₂ switch to display a desired message or service information and confirming the contents, the S ₃ switch is operated to display those data. Can be erased.

If M = 1 is not determined in the determination of step ST64, it means that the S ₃ switch is operated for time adjustment in the mode of M = 2, and the time data of date, hour, minute, and second is corrected ( ST72).

If an operation of the S ₃ switches the switch is determined in the step ST55, and when the S ₄ switch is operated, it is determined whether alarm flag A is set (A = 1) (ST73) . When the S ₄ switch is operated with A = 1, the flag A is reset and the alarm sound is stopped (ST74). If A = 1 is not determined in step ST73, it is determined whether the display flag D is "1" (ST7
5) If D = 0, the process is terminated as it is, and if D = 1, the process proceeds to step ST40 of FIG. 6 (a), the mode M is set to 0, and the display flag is reset.
Switch to the standby state.

FIG. 7 is a diagram showing the transition of the display state when the S ₁ and S ₂ switches are operated.

Standby state with no switch operation (M = 0 and D = 0)
Then, the receiver displays the message and the current time if it stores a contact message from the beer company that informs the contract deadline, and displays only the current time if the message is not stored. The display on the upper side of FIG. 7 (1) shows an example of the display at this time, and the contact message sent from the pager company notifying the contract deadline is automatically displayed when switching to the standby state.

When the pointer P is updated by operating the S ₂ switch in this state, first the message with the latest reception time and the reception time are displayed (Fig. 7 (2)), and each time the S ₂ switch is operated, the message is received. The messages are displayed in order from the newest time (FIG. 7, (3), (4)).

On the other hand, if the S ₁ switch is operated in any of the display states of M = 0, the mode is switched to the display mode of the service information of M = 1. Immediately after switching to this service information display mode, a contact message from the information company, such as a message notifying you that the contract deadline is about to expire, or a message that the contract has expired and the service has been canceled. A notification message or the like is first displayed (Fig. 7 (5)).

At this time, if no contact message from the information service company is stored, the type of service information provided and the like are displayed on the upper portion of the display unit 11.

If the S ₂ switch is provided in this service information display mode, information such as the stock market received is displayed, for example, as shown in Fig. 7 (6), the stock price of company A is 1450 yen and the stock price of company B is 2900 yen at 15:00. Is displayed. Hereinafter, every time the S ₂ switch is operated, the stock information stored in the order of reception time is displayed (FIGS. 7 (7) and (8)).

If the S ₁ switch is operated in any of the display states of M = 1, the time display mode for time adjustment of M = 2 (not shown) is set, and M = 2 is set in the normal mode of M = 0. to return when the operation of the S ₁ switch at a mode.

As described above, the contact message sent from the paging service company indicating the contract deadline, etc. is stored separately from the normal call message, and when the message is not received or read, for example, the receiver executes a special process. I'm trying to display that contact message when not waiting. Therefore, even if a large number of call messages are received after receiving the contact message from the paging service company, the previously received contact message is not erased. Moreover, since those contact messages are displayed when the paging receiver is in the standby state, the contact message can be confirmed without the reading operation of the message carried by the receiver carrier, Never miss a contact message.

[Effect of device]

According to the present invention, since the received specific message is always displayed when the receiver is in the standby state, it is possible to reliably convey the content of the specific message. Furthermore, after receiving the specific message, the specific message is not erased even when a large number of normal call messages are received, so it is possible to avoid the situation where the specific message is not displayed even though the receiver is in the standby state, The content of the specific message can be transmitted more reliably.
