Abstract

PROBLEM TO BE SOLVED: To provide a receiver where a next page mark in the case that only display information (time stamp or the like) other than a message is present on a next page is displayed in a different page mark when there is any message in the case of displaying a received message over a plurality of pages. SOLUTION: A CPU 6 discriminates whether or not a data capacity (byte) of contents data of selected head line data stored in an IP message memory area in a RAM 10 exceeds a display permissible data amount (30 full size characters: 60 bytes) per page in an information message of a display section 8 and whether or not the message extends over a plurality of pages. When the message is displayed on a plurality of pages, the CPU 6 subtracts the display permissible data amount from the data capacity. When no residue is in existence, since only a 'time stamp' is displayed on a next page, the next page mark is discriminatingly displayed when contents data are displayed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus applied to an information communication system for transmitting and receiving text style data, such as a paging system.

[0002]

2. Description of the Related Art Conventionally, as a communication system for transmitting and receiving character information using a telephone line, there are a wireless paging system and an electronic mail system. As a transmission data format in the wireless paging system, there is a POCSAG system.

[0003] However, with the development of mobile communication technology in recent years, service usage fees have been reduced and personal use, especially business use as well as young people, in particular, have spread, and as a result, the number of service subscribers has increased. , It is difficult to provide sufficient services.

As described above, with the recent rapid increase in demand and expansion of functions, it is necessary to enhance services.
As a result, in the paging system, the standard "R
An advanced paging method defined in CRSTD-43 has been introduced.

[0005] In this advanced paging system, a service provided by using a data structure defined by the standard specification "RCR STD-43" includes a paging receiver (hereinafter referred to as a pager) in addition to a basic paging service. A message number is added to the call from the center side equipment for each address of the address and transmitted. Also, the center can manage the message "Message serial number service", and can receive event information and regional information message "Information" Service ”.

A subscriber who uses a pager corresponding to the advanced paging system can select a basic service and additional services. For example, when the above-mentioned “information service” is selected, one subscriber is required. An information message of a maximum of 50 characters (200 bytes) can be received in each reception.

[0007] Since the number of characters that can be displayed on the display unit of the pager is limited, when a long message exceeding the number of characters that can be displayed is received from the paging center, the pager side determines the number of characters that can be displayed in the received message. The page is displayed on the display unit as a page unit, and a next page mark indicating that there is a next page is displayed in the display unit to urge the user to switch to the next page.

For example, as shown in FIG. 11A, a display unit 1 provided in a housing 101 of a pager 100 is provided.
When a received message covering a plurality of pages is displayed in 02, a next page mark “<” displayed in the upper right portion of the display screen is displayed. In this display example, the display unit 10
The number of characters of the received message that can be displayed in 2 is 3 double-byte characters
If it is 0 characters (60 bytes) and the end of the sentence is exactly the 30th character, the cursor key 10
When the next page shown in FIG. 5B is displayed by the operation of No. 4, only the time stamp indicating the reception date and time is displayed as display information accompanying this received message.

[0009]

However, since the display of the next page mark is a display only indicating whether or not there is a next page, as shown in FIG. Even when the next page has only one stamp, there is a problem that the next page mark is displayed and only the time stamp is displayed when the next page is viewed.

[0010] For this reason, the user of the pager cannot determine whether there is a remaining message on the next page or only a time stamp when displaying a message on a plurality of pages. There was a problem that would go.

An object of the present invention is to display a next page mark which is different from a normal one when displaying a received message over a plurality of pages when only information (such as a time stamp) other than the message exists on the next page. An object of the present invention is to provide a receiving device that can be identified and displayed by a page mark.

A case where the present invention is applied to a paging receiver (pager) in a paging system employing the above-described advanced radio paging system will be described below with reference to FIGS.

FIGS. 1 to 8 show an embodiment of a pager to which the receiving apparatus of the present invention is applied.

First, the configuration will be described. FIG. 1 is a block diagram showing a main configuration inside pager 1 in the present embodiment. 1, a pager 1 includes an antenna 2, an RF receiver 3, a decoder 4, an ID-ROM 5,
CPU 6, input unit 7, display unit 8, ROM 9, RAM 1
0, speaker 11, vibrator 12, and LED
13.

The antenna 2 receives data transmitted by a paging center (not shown) from a transmitting antenna in a format based on the RCRSTD-43 standard, and outputs the data to the RF receiving unit 3.

The RF receiver 3 is connected to the decoder 4 and is driven based on a control signal from the decoder 4 to demodulate and detect received data. The RF receiving unit 3 takes in the synchronizing unit 1 (S1) C1 in FIG. 10 and selectively outputs serial bit data to the decoder 103 according to a binary or quaternary modulation method.

The decoder 4 rearranges the binary or quaternary serial bit data input from the RF receiver 3 into 8-bit parallel data and outputs it to the CPU 6. Also, the decoder 4 outputs the address data of the address field (AF) C5 received by the CPU 6,
Upon receiving a detection signal output upon matching after matching with the address data registered in the ID-ROM 5, the vector field (VF) C6 and the message field (MF) of the frame including the matched address data are received.
It has a function of instructing the RF receiving unit 3 to continuously receive all data of C7.

The ID-ROM 5 stores frame number data of a frame to be received set in the pager 1 and address data (32 bits) for detecting a call.
And the call number are stored in association with the 3-bit vector types v2, v1, and v0 set in the vector field (VF) C6.

For example, in the case of the pager 1, the frame number data to be received is '10', and three types of the individual call address data #A according to the vector type and the frame number data to be received are '10'. 32 ', which stores one type of address for the information providing service address #B.

The individual call address data #A
Are set in three types depending on the difference in the setting of the vector type. Specifically, a first address (for basic call), a second address (for dual call), and a third address (for serial number service) are set. Call numbers corresponding to them are stored. These 1st to 3rd
The address is for an NP paging service.

Then, the address #X for the information providing service
Is set for the 4th address (information providing service), and is written to the pager 1 when the owner of the pager 1 applies for the information providing service at the paging center 4. Also, since this 4th address data is for the IP paging service,
The vector type is fixed at (1,1,0) and is stored together with the corresponding calling number.

CPU (Central Processing Unit) 6
Analyzes the incoming bit data based on various control programs stored in the ROM 115,
Each circuit in the pager 1 is controlled according to various control signals input from the input unit 7.

In addition, the CPU 6 sets the word structure (in the vector field (VF) C6 of the frame C shown in FIG. 10) in the data periodically received in the incoming call processing (see FIGS. 4 and 5) described later. v2, v1,
v0) has a vector type of (1,1,0)
Is detected, it is determined that the format of the message of this data corresponds to the IP paging service, and the subsequent bit data string is sequentially divided into 8-bit units, and the JIS8 code stored in the ROM 9 in advance is read. A character (character) designated for conversion is extracted with reference to a conversion table (not shown), and the information service data is divided into headline data and content data for each storage address, and the IP message memory in RAM 10 is stored. It is stored in the area 10b.

When the CPU 6 detects that the vector type is not (1, 1, 0) in the incoming data in the incoming call process, the CPU 6 determines that the format of the message of this data corresponds to the NP paging service. Then, the subsequent bit data string is stored in N
The received message is stored in the P message memory area 10a, and the received message stored is displayed.

Further, when the CPU 6 detects the designation of the message reading mode in the incoming call processing, the CPU 6 sets the page data of the head line data selected by the key operation of the cursor key from the head line data displayed in a list on the display unit 7. When a key operation of a key is detected, information message data display processing for reading out content data, which is detailed information content of the selected headline data, from the IP message memory area 10b and displaying the data on the display unit 8 (see FIG. 6) Execute

In this information message data display processing, the CPU 6 determines the data capacity (byte) of the content data of the selected headline data stored in the IP message memory area 10 b in the RAM 10 by the information message of the display unit 8. It is determined whether or not the display is over a plurality of pages exceeding the display allowable data amount per page (full-width 30 characters: 60 bytes). Depending on the presence or absence, if there is no residue, only the "time stamp" is displayed on the next page. Therefore, the next page mark when displaying the content data is identified and displayed. Display the page mark normally.

The input unit 7 has a mode key 203 for detecting a mode switching operation such as an incoming call waiting mode, a notification mode setting mode, a message reading mode, etc., as in a pager 200 shown in FIG. A cursor key 204 for detecting a menu selection operation or a selection operation of headline data displayed in a list on the display unit 8 in the message reading mode, power ON / OFF switching, reset detection of incoming call notification, and information service data A main switch 205 for detecting whether or not the user has confirmed the display of the headline data at the time of the incoming call; and determining various settings in each of the above modes, or corresponding to the headline data selected in the message reading mode. Content data Made from the page key 206 for detecting the actual out operation, it outputs various operation signal corresponding to the input operation of each key to CPU6.

The display unit 8 includes a display buffer (not shown), an EL
It is composed of, for example, a liquid crystal panel of a dot matrix including a backlight, a driver, and the like. An instruction from the CPU 6 is input to the driver, and is driven and controlled by the driver to display information such as a message on the liquid crystal panel.
It is assumed that the display allowable data amount per page of the information message on the display unit 8 is “30 double-byte characters: 60 bytes”.

A ROM (Read Only Memory) 9 is a non-volatile storage medium for storing a display control program, other various programs, and the like.

The RAM (Random Access Memory) 10
As shown in FIG. 2, 1 is set in the ID-ROM 5.
an NP message memory area 10a for storing message data received at addresses st to 3rd;
and an IP message memory area 10b for storing and managing information service data received at address h.

The NP message memory area 10a stores NP paging service message data received at the first to third addresses set in the ID-ROM 5.

In the IP message memory area 10b, as shown in FIG. 3, information service data received at the 4th address is stored separately for each storage address into headline data and content data. Further, a data capacity (byte) indicating the data capacity of the content data and a time stamp indicating the reception date and time are stored in association with each stored information service data.

If the data structure of the information service data transmitted from the paging center is not configured to distinguish between the headline data and the content data, line feed, line feed,
Extract display control data such as space as identification information and extract and store data before that as headline data,
Data after this is stored as content data.

The speaker 11 sounds a ringing tone at the time of an incoming call based on a drive signal from the CPU 6 or sounds a predetermined melody sound in response to a message display output. The vibrator 12 generates vibration at the time of an incoming call or the like based on a drive signal from the CPU 6. LED (Light Emitting Dio
de) 13 emits light or blinks at the time of an incoming call or the like based on a drive signal from the CPU 6.

Next, the operation of this embodiment will be described.

The incoming call processing of the pager 1 that has received the information service data from the paging center will be described with reference to the flowcharts shown in FIGS.

After turning on the power by operating the power switch, the CPU 6 in the pager 1 executes the initialization setting of each circuit section and the setting of the control data to execute the frame No. 0 (the frame in which the time correction information is stored) and the frame of the own frame are searched (step A1). When the frame is synchronized (step A2), the apparatus enters the intermittent reception standby state (step A3). Then, first, the CPU 6 sets the input unit 7
It is checked whether or not a read mode input is detected by a key operation of the cursor key 204 in (A).
4).

That is, in the incoming call processing, the information service data stored in the IP message memory area 11b in the RAM 10 is read in the incoming call processing of the information service data transmitted from the information service center via the paging center according to the transmission schedule. It is checked whether a read mode instruction has been detected.

If the read mode instruction is not detected in the read mode detection processing, the presence or absence of the own frame timing is detected from the transmission data wirelessly transmitted from the paging center via the transmission antenna by the antenna 2 by the intermittent call reception processing ( Step A5). If the transmission timing of the own frame is not detected, step A
3 and returns to the intermittent reception processing, and when the transmission timing of the own frame is detected, the frame data is fetched and the reception processing is started (step A6). And antenna 2
, A modulated wave of the received signal is received and output to the RF receiving unit 3, further detected and demodulated, and output to the decoder 4.

The decoder 4 rearranges the serial data corresponding to the transmission speed input from the RF receiving section 3 into 8-bit parallel data and outputs it to the CPU 6. After this CP
U6 captures the 8-bit parallel data output from the decoder 4, compares the address data registered in the ID-ROM 5 with the address data in the address field (AF) C5, and determines the address data included in the ID code. Detects whether the address data matches its own address data (step A7). If they do not match, the receiving process is terminated (step A8), and the process returns to step A3. If they match, a match signal is output and the decoder 4 receives all the data in this frame. The receiving operation of the RF receiving unit 3 is continued.

Subsequently, all data of one frame transmitted from the information service center via the paging center and the transmission antenna is taken in. Then, it is detected whether or not the address data whose match has been detected first is the 4th address (step A9). If the address is not the 4th address, the fetched frame data is subjected to an error
Is stored in the NP message memory area 10a (step A10).
Analyzes the contents of the self-addressed message data stored in
Notification sound of speaker 11 driven by CPU 6, L
The incoming call is notified by the blinking of the ED 13 or the vibration of the vibrator 12, the analyzed message is displayed on the display unit 8 (step A11), and the process returns to the intermittent reception state of step A3.

If the address data for which a match was previously detected in step A9 is the 4th address, error correction processing is performed, and the fetched information service data is stored in a vacant area in the IP message memory area 10b together with the arrival date and time, or If the data has been written in all of them, the information service data and the arrival date and time are overwritten and stored in the memory area where the information service data with the old arrival date and time is stored (step A12), and step A3 is executed.
To the intermittent reception state.

If a read mode instruction is detected in the read mode detection process of step A4,
The PU 6 shifts to the read mode processing after step B1 in FIG.

When a read mode instruction is input, first, the CPU 6 displays a list of read menus on the display unit 8 (step B1). In this readout menu,
"Display of incoming message" (reading of NP message memory area 10a) and "Display of information service"
(Reading of IP message memory area 10b) 2
It is assumed that one menu is set.

In the displayed read menu,
The CPU 6 determines whether “display of an incoming message” is selected and determined by operating the cursor key 204 of the input unit 7 and each key of the main switch 205 (step B2), or whether “display of information service” is selected and determined (step B).
3) are respectively detected. When it is detected that "display information service" is selected and determined, the headline data in IP message memory area 10b in FIG. 3 is searched, and a list showing the contents of the searched headline data is displayed on display unit 8. A list is displayed (step B4).

When it is detected that a particular list has been selected and determined by operating the cursor keys 204 and the main switch 205 of the input unit 7 on the displayed list (step B5), the CPU 6
Shifts to the information message data display processing after step B41 in FIG. 6 in which the corresponding content data, data capacity (byte) and time stamp data are read from the IP message memory area 10b and displayed on the display unit 8 (step B41). B6).

In FIG. 6, first, the CPU 6 sets the data capacity (byte) of the selected and determined content data to the display allowable data amount of the display unit 8 (30 double-byte characters: 60 bytes).
(Step B4).
1) If the data amount does not exceed the display allowable data amount, the process proceeds to step B46, the information service message is displayed on the display unit 8, and the process proceeds to step B7 in FIG.

If the data capacity (byte) of the selected and determined content data exceeds the display allowable data amount (30 double-byte characters: 60 bytes) of the display unit 8, the data capacity (byte) is displayed. Subtraction is performed with the data amount "60" (step B42), and it is detected whether or not there is a residue (step B43). If there is no remaining message, the message is displayed on the display unit 8 on a plurality of pages, and only the “time stamp” is displayed on the last page. Therefore, the display unit 8 has only information other than the message. Is displayed (step B44), the information service message is displayed on the display unit 8 (step B46), and the process proceeds to step B7 in FIG.

FIG. 7 shows a display example in step B44.
Shown in In FIG. 7 (a), a report from the IP message memory area 10b of FIG. 3 stating that "mobile phone radio waves are harmless to the human body" as a content data, Study Group "compiled the 28th. "Is displayed. In this case, the data capacity is “120 bytes”, and there is no remainder when subtracting the display allowable data amount “60”, so that only the time stamp is displayed on the display screen of the next page as shown in FIG.

At this time, the next page mark “<” displayed in the display unit 202 of FIG. 11A is displayed in a shaded state as an identification display indicating that there is only information other than the message as described above. You.

If there is a residue in step B43, the message is displayed on the display unit 8 on a plurality of pages, and the message is also displayed on the last page. The next page mark is displayed (step B45), the information service message is displayed on the display unit 8 (step B46), and the process proceeds to step B7 in FIG.

FIG. 8 shows a display example in step B45.
Shown in In FIG. 8 (a), the power reactor / nuclear fuel development corporation broke down on the 28th in the sodium leak accident of the fast breeder reactor “Monju” as content data from the IP message memory area 10b of FIG. The missing thermometer pod tip was found in a distributor to regulate the flow of sodium. "Is displayed. In this case, the data capacity is “162 bytes”, and there is a remainder when subtracted by the display allowable data amount “60”. Therefore, as shown in FIG. Is displayed.

At this time, the next page mark "<" displayed in the display section 202 of FIG. 11A is displayed in a normal state, indicating that there is a message on the next page.

Then, in step B7 in FIG. 5, when a release instruction is detected by operating the mode key 203 on the input unit 7, the process returns to the intermittent reception state in step A3 in FIG. When a key operation other than the mode key 203 on the input unit 7 is detected, the next page and the page are incremented according to the key operation, and the number of characters of the message to be displayed is calculated.

When detecting that the "display of incoming message" is selected and determined in step B2 of FIG. 5, the CPU 6 shifts to the processing of step B8 and deletes the incoming message data stored in the NP message memory area 10a. Search for. Then, a list is created by extracting a predetermined number of characters from the beginning of the searched incoming message data and displayed on the display unit 8 (step B9). The cursor key 204 and the main switch 205 in the input unit 7 are displayed.
When it is detected that specific incoming message data is selected and determined by each key operation (step B10), the selected incoming message data is read from the NP message memory area 10a and displayed on the display unit 8 (step B11). ). When a release instruction is detected by operating the mode key 203 on the input unit 7 (step B12), the process returns to the intermittent reception state in step A3.

As described above, in the pager 1 according to the present embodiment, when displaying the received information service message in the information service data received in the above-described incoming call processing, the display allowance of the information message per page of the display unit 8 per page is allowed. It is determined whether or not the data is over a plurality of pages exceeding the data amount (30 double-byte characters: 60 bytes). If there is no residue, only the "time stamp" is displayed on the next page, so the next page mark when displaying the content data is shaded and displayed for identification, and if there is a residue, the next page when displaying the content data The mark is displayed normally so that there is a message on the next page and when there is information other than the message , The display form of the next page mark is distinguished.

Therefore, the user of the pager 1 can determine in advance whether or not it is necessary to look at the next page of the message displayed on the display unit 8 and perform the next page operation. Useless operations can be reduced during the display operation.

In the above embodiment, the case where the display form of the next page mark is distinguished between the case where there is a message on the next page and the case where there is information other than the message has been described. As a form, for example,
The normal display of the next page mark may be flashed, or the display of the next page mark itself may be changed.

In the above embodiment, the case where the display form of the next page mark is distinguished between the case where there is a message on the next page and the case where there is information other than the message has been described. A method of notifying by sound as a form is also conceivable.

Hereinafter, an information message data display process to which a method of notifying a difference between a case where there is a message on the next page and a case where there is information other than the message by sound will be described with reference to a flowchart shown in FIG.

In FIG. 9, first, the CPU 6 sets the data capacity (byte) of the selected and determined content data to the display allowable data amount of the display unit 8 (30 double-byte characters: 60 bytes).
(Step B41).
1) If the data amount does not exceed the display allowable data amount, the process proceeds to step B412, where the information service message is displayed on the display unit 8, and the process proceeds to step B7 in FIG.

If the data capacity (byte) of the selected and determined content data exceeds the display allowable data amount (30 double-byte characters: 60 bytes) of the display unit 8, the data capacity (byte) is displayed. Subtraction is performed with the data amount “60” (step B413), and it is detected whether or not there is a residue (step B414). If there is no remaining message, the message is displayed on the display unit 8 on a plurality of pages, and only the “time stamp” is displayed on the last page. The next page mark is displayed on the display unit 8 ( (Step B415), the information service message is displayed on the display unit 8 (Step B416), and the routine goes to Step B7 of FIG.

If there is a residue in step B414, the message is displayed on the display unit 8 on a plurality of pages, and the message is also displayed on the last page. Is displayed (step B417), and the information service message is displayed on the display unit 8 (step B418).

Then, the CPU 6 determines whether or not the message to be displayed on the next page is only the time stamp other than the message (step B419). If the message is only the time stamp other than the message, the CPU 6 proceeds to step B7 in FIG. Then, if there is a message on the next page, a short sound is output from the speaker 11 to indicate that there is a message on the next page (step B420), and the process proceeds to step B7 in FIG.

As described above, when there is a message on the next page, the presence of the message on the next page is notified by sound, so that the user of the pager 1 can be prompted to switch the display to the next page. Can be easily distinguished from the case where there is no message, and useless operation can be reduced when displaying the information service message.

Note that the sound is notified when there is a message on the next page, but may be sounded when there is no message on the next page. In addition, as the notification form, the notification may be made by a change in color, a change in light, a change in display shape, or the like. In addition, the time stamp at the time of receiving a message has been described as an example of display information. However, the present invention is not limited to this.

Further, the present invention provides, as an example of the embodiment,
Although the pager applied to the information service in the paging system has been described, the present invention is not limited to this embodiment, and can be applied to a receiving device depending on various information communication systems (for example, an electronic mail system).

For example, a portable communication terminal which is applied to a radio telephone system and a PHS system and has a function of displaying data transmitted information, a PHS terminal with a display function,
Alternatively, a text broadcast receiving apparatus applied to a broadcast system that broadcasts text information together with audio information using an FM signal may be used. The present invention is also applicable to a wireless communication terminal applied to an MCA wireless data communication system such as a teleterminal system.
