The paging center generates transmission data in accordance with the data configuration of FIG. 9 defined by RCR STD-43 based on the call number and information service data provided from the personal computer via the public line network,
Send to pager.

Hereinafter, an incoming call process executed by the CPU 16 of the pager 1 will be described with reference to a flowchart shown in FIG. CPU 16 in pager 1
After the power is turned on by operating the power switch, the initialization of each circuit unit and the setting of control data are performed, and when the frame synchronization is achieved, the mode shifts to the intermittent reception mode (step S1).
Then, it is determined whether or not it is the own frame reception timing (step S2), and if not, the process returns to step S1.

If the CPU 16 determines that it is time to receive its own frame, it starts the incoming call process (step S3). That is, the modulated wave of the signal received by the antenna 11 is output to the receiving unit 12, further detected and demodulated, and output to the decoder 13. The decoder 13 rearranges the serial data corresponding to the frame type input from the receiving unit 12 into 8-bit parallel data, outputs the parallel data to the bus B, and stores it in the buffer memory 14. Thereafter, the CPU 16 performs an interleave recovery / error correction process on the data sequentially stored in the buffer memory 14 to determine the address data in the address field (AF) C5 and the vector type in the vector field (VF) C6. Is compared with the combination of the address data registered in the ID-ROM 17 and the vector type, and it is determined whether or not there is an incoming call to the pager 1. If none of them match, the incoming call processing is terminated and the data stored in the buffer memory 14 is erased. Conversely, if any of them matches, the received data is continuously taken in.

Next, the CPU 16 determines whether the current incoming call is an individual call or an information service from the combination of the matched address data and the vector type (step S).
4). If it is determined that the current call is for the information service, the current mode of the pager 1 is detected (step S5). If the current mode is the call waiting mode, the information received on the display unit 24 is displayed. A message based on the service data is displayed (step S6). Then, it is determined whether or not a key operation on the key input unit 25 is detected (step S7). When the key operation is detected, it is determined whether the operated key is the reset key or the cross key. (Step S8). If the operated key is the reset key, the process returns to step S1.

If the operated key is a cross key, the message displayed on the display unit 24 in step S6 is swept according to the operation direction of the cross key in accordance with the operation direction of the cross key. (Step S9). Then, it is determined whether or not an operation in the up-down direction is detected with the cross key (step S10). If not detected, the process returns to step S6. When a reverse operation is detected with the four-way controller,
The sweep display of the message is stopped (step S
11), and return to step S7. On the other hand, step S5
In the case where the current mode is a mode other than the call waiting mode such as the notification mode setting mode and the alarm setting mode, the received information service data is stored in the information service storage unit 202 of the information service RAM 20, By detecting the display control flag corresponding to the information service program corresponding to the received information service data stored in the display setting unit 201 in the service RAM 20, the information service data is displayed by the user in advance. It is determined whether the program is a set program (step S12).

If the display control flag is "0", that is, if it is set that the information service data received by the user need not be displayed, the process proceeds to step S15, and the display of the display unit 24 is performed. The display data of the mode currently being processed is continuously displayed on the entire screen.

If the display control flag is "1", that is, if the information service data received by the user is set to be displayed on one line at the lower end of the display screen of the display unit 24, the display control flag is set. Based on the display control program in the ROM 21, data to be displayed in the currently ongoing mode is stored in each mode display area 23a of the driver / display buffer 23, and the driver of the driver / display buffer 23 is drive-controlled. Thereby, the display screen of the display unit 24 is divided, and the data is displayed in a portion excluding one line at the lower end.

The message data based on the information service data stored in the information service storage section 202 of the information service RAM 20 is stored in the information service data sweep display area 23b of the display buffer 23, and the driver 23 is driven. By controlling, the data is displayed on one line at the lower end of the display screen of the divided display unit 24. (Step S13).

FIG. 6A shows the display unit 24 when a message based on the received information service data is displayed in one line at the bottom of the display screen in step S12 when the current mode is the alarm setting mode. It is a figure which shows the display screen of. On the lower line of the display screen, a message based on the received information service data, "Pro Baseball News", is displayed, and on the part other than the lower line, a display screen of the alarm setting mode is displayed. ing.

Then, it is determined whether or not a key operation on the key input section 25 has been detected (step S14). When the key operation is detected, whether the operated key is a reset key or a cross key is determined. Is determined (step S15). If it is a reset key, display unit 2
The display of the message based on the information service data displayed on the lower line of the display screen of No. 4 is stopped, the display data of the mode currently being processed is displayed on the entire display screen (step S16), and the process proceeds to step S1. Return.

When the operated key is a cross key, a message based on the information service data displayed on one line at the lower end of the display screen of the display unit 24 is displayed in the operation direction of the cross key. Therefore, a sweep display is performed (step S17). Then, it is determined whether or not an operation in the up-down direction is detected in the operation direction of the cross key (step S18).
Return to 14. Conversely, when an up / down operation is detected with the cross key, the sweep display of the message is stopped (step S19), and the process returns to step S14.

FIG. 6B shows that in step S17,
FIG. 10 is a diagram showing a display screen of the display unit 24 when a message based on the information service data displayed on one line at the lower end of the display screen is swept. On the display screen, the message displayed on one line at the lower end of the display screen shown in FIG. 6A is swept.
If it is determined in step S4 that the current incoming call is for an individual call, the incoming call is notified and the incoming message is displayed irrespective of the mode in which it is being processed (step S20).

As described above, the pager 1 of the present embodiment determines the current mode in the incoming call processing, and if the mode is other than the incoming call waiting mode, the information service R
The display control flag in the AM 20 is detected, and when the received information service data is a program set to be displayed in advance by the user, the display unit 24 is displayed based on the display control program in the display control ROM 21. , The display data in the current mode is displayed in a portion excluding one line at the lower end, a message based on the information service data is displayed at one line at the lower end, and the operation direction of the cross key of the key input unit 25 is displayed. In order to control the sweep display of the message, even in a mode other than waiting for an incoming call, when information service data of an information service program set to be displayed in advance by the user arrives, a message based on the information service data is transmitted. It is displayed on one line at the bottom of the display screen, and a sweep table is displayed according to key operation. It can be.

Therefore, even in modes other than the incoming call waiting mode,
Information designated by the user, such as information of interest to the user, is displayed in a sweep display on a part of the display screen, thereby preventing the information from being overwritten by other data and deleted without being confirmed by the user. In addition, the user can automatically know what kind of information service data is currently received, thereby improving usability as a pager information providing service.

Further, for information that the user does not want to perform the sweep display, such as information that is not of interest to the user, the sweep display is not performed, so that only the information necessary for the user can be promptly confirmed.

Further, since the information displayed on a part of the display screen is swept in response to the key operation by the user, the information can be swept and displayed at the discretion of the user. In such a case, the sweep display is stopped in accordance with the condition (1), so that the sweep display can be stopped at the discretion of the user, making it easier for the user to confirm the information.

In this embodiment, the display setting unit 201 shown in FIG. 3 stores a display control flag of either “1” or “0” for each information service program, and stores the display control flag. Is "1", a message based on the information service data is displayed in a sweep line (flow display) on one line at the lower end of the display screen of the display unit 24. When the display control flag is "0", Although the message based on the received information service data is not displayed, the display screen of the current mode is continuously displayed,
As in a modified example of the display setting unit 201 shown in FIG. 7, when a line feed and a space are detected from a message displayed during the sweep display, a line feed and a space stop flag for setting the stop of the sweep display for a certain time each time are detected. May be set in association with each other, a line feed and a space may be detected from the message during the sweep display, and the sweep display may be stopped for a certain period of time.

As in a modification of the display setting section 201 shown in FIG. 8, when a specific keyword is detected from the display control flag and the message being displayed in the sweep mode, the stop of the sweep display for a certain time is set each time. You may do it.
This makes it easier for the user to understand the message breaks in the sweep display.

Further, in the present embodiment, the display setting section 201 in the information service RAM 20 is configured to set a display control flag for each information service program, and to display a message for each information service program according to the user's interest or the like. The user can set whether or not to set the display control flag for each time zone of the day, and the user can set whether or not to display a message according to the time of receiving the information service data, etc. Alternatively, the display control flag may be set for each of the other categories.

Further, the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be appropriately changed without departing from the gist of the present invention. For example, in the above embodiment, a case has been described in which the present invention is applied to a paging receiver corresponding to the advanced radio paging method, but this is not limited to the paging receiver,
