[0002]

2. Description of the Related Art There is a selective call receiving system having a function of displaying a received message. As such a receiving system, for example, Japanese Unexamined Utility Model Application Publication No.
No. 3 publication.

The receiving system described in this publication receives and displays service information provided by an information service company via a wireless paging system.
A determination means is provided for determining whether the received message is a communication message from a reception service company. When the determination message is a communication message, the message is stored in storage means separately from the service information, and the display mode is switched to the service information display mode. When the contact message is displayed first.

[0004]

However, since this type of receiving system is an information service using a paging system, a paging receiver (hereinafter referred to as a pager) having a display capability corresponding to the amount of information is provided. For example, a pager capable of receiving 20 characters 2 lines or 20 characters 4 lines is mainly used for one screen, and a large display (LCD) is used for a receiver having a high display capability.
Etc.), and a display driver for driving the display is required, so that there is a problem that the equipment becomes expensive.

[0005] In this type of system, a pager in which one screen is scrolled and displayed in one line is also on the market. However, in the case of an individual call service, the message length is short and the information service is not available. In many cases, the format is not a fixed format, so that there is a problem that scrolling makes it difficult to read.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a selective call receiving system and a selective call receiving method which can easily read a message suitable for a service type and have good operability.

[0007]

A pager used in the selective call receiving system and the selective call receiving method of the present invention has display means for one line per screen, and switches the display mode depending on whether the received message is an individual call or an information service. In the case of an information service, a display drive unit for performing scroll display is provided.

Therefore, according to the present invention, the display method is automatically switched depending on whether the received service is an individual call or an information service. Therefore, it is possible to provide a pager in which a message can be easily read even with a display means of one line on one screen. In addition, a message suitable for the type of service can be easily read, and the operability can be improved.

Further, it is possible to reduce the cost of equipment optimal for both the individual call service and the information reception service. As a result, when displaying a long message such as an information service, the information is displayed by scrolling for each character as is generally displayed on an electronic display panel, so that the display capability of a low-line display is low. Since a long sentence can be displayed in an easy-to-read form even on a container, the display method changes depending on the type of service, so that it is possible to provide a receiver that is easy to read according to the nature of the message. Further, since it can be realized by a display device or a display drive unit having a low display capability, a less expensive receiver can be provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating a configuration of a pager system in an embodiment of a selective call receiving system and a selective call receiving method according to the present invention.

FIG. 1 is a block diagram showing a pager system according to an embodiment of the present invention. The antenna 1 efficiently converts the electromagnetic wave energy modulated by the synchronization signal, the call signal and the message signal into an electric signal and supplies the electric signal to the receiving unit 2.
The receiving unit 2 demodulates the electric signal into a baseband signal, and supplies the baseband signal demodulated to the decoder unit 3 to the decoder unit 3. The decoder unit 3 detects a synchronization signal from the baseband signal and reads a received signal. When the decoder unit 3 generates a call signal corresponding to its own call ID stored in the ID storage unit 5 in the received signal, it decodes the subsequent message signal.

FIG. 2 is a signal format showing an example of a signal system. The receiving operation of this type of selective calling receiver is a widely and generally known technique, and detailed description thereof will be omitted, but the operation of the above-described decoder unit 3 will be briefly described. The decoder unit 3 performs bit synchronization with the preamble signal 21 and detects the frame synchronization signal 22 to recognize the timing of each word.

The format shown in FIG. 2 is an example when the own ID signal 23 is at the third position. Upon detecting its own ID signal 23, it receives message words (in this example, 3 words = 8 characters of nuts to alpha) Ml (24), M2 (25), M3 (26) following this ID signal, and Of the message signal is detected by detecting the ID signal or IDLE signal 27 (a signal transmitted when there is no call signal or message signal to be transmitted).

The decoder section 3 converts the received message signals Ml (24) to M3 (26) into ASCII codes and stores them in the message storage section 6 via the message processing section 4. The ID storage unit 5 generally stores one or more IDs (IDs).
1, ID2, ID3,..., IDn). The ID can be assigned according to the type of an information service such as a weather forecast or news, in addition to a personal call. The message storage unit 6 stores the received messages by classifying them into various types (for personal calls, for information services, etc.).

FIG. 3 is a diagram showing an example of correspondence between six IDs (addresses) and service types (individual call or information service). When the own ID signal is detected and the message signal is received, the decoder unit 3 drives the notification unit 8 to generate a sound with the speaker 9 to notify the user that the message has been received. In addition to the speaker 9, various types of notification devices, such as a vibrator by vibration and a light-emitting diode blinking by light, can be used.

In the prior art, the notification can be performed by causing the decoder unit 3 or the notification unit 8 to perform an automatic reset operation for stopping the notification after a lapse of a predetermined time from the start of the notification. It is also possible to manually reset the operation of the notification unit 8 by the decoder unit 3 via the message processing unit 4. At this time,
The received message activates the display drive unit 14 (display drive unit A or display drive unit B) via the message processing unit, and displays the message on the display 15.

FIG. 6 is a flowchart showing an example of the receiving operation. In FIG. 6, whether or not the own address of step 61 (hereinafter, referred to as ST61) is received is normally included in the received signal and the own address stored in the ID storage unit 5 in the standby state. Check with the address signal. As a result of the comparison, when the own address is received in ST62, a message receiving process is performed in ST63.

In this embodiment, as described above, in ST64, the end of the message is determined based on whether or not another ID or IDLE signal is detected. When another ID or IDLE signal is received, the process proceeds to ST65, and the received message is stored in the message storage unit 6.

In this embodiment, when the message receiving process is completed, the notifying unit 8 is activated in ST66 to activate the speaker 9
Is notified of the call by driving. Next, S
