Description

How to display continuous messages on a pager receiver

TECHNICAL FIELD The present invention relates to radio call receivers, and more particularly, to a method for displaying consecutively received messages.

In general, a radio paging receiver receives and analyzes a specific type of radio paging signal and then displays when the paging signal is information related to itself or an alarm indicating that information related to the paging signal is received. It executes a function that generates an alert. In this case, when a wireless call signal is received as information related to itself, the call information is normally displayed on a liquid crystal display (LCD), and an alarm indicating this is generated and transmitted to the outside through a speaker. Thus, the user can know that the information related to him is called wirelessly.

A liquid crystal display (LCD) is used as a typical device for displaying radio call information in the radio call receiver. Such a liquid crystal display has a limit of capacity that can be displayed, unlike a liquid crystal display used for other communication devices and electronic devices. For example, a liquid crystal display attached to WITHME, a wireless paging receiver manufactured and sold by Samsung Electronics Co., Ltd., may display 16 characters in a row, and thus 16 characters may be displayed. A liquid crystal display attached to LIBERO, a radio call receiver manufactured and sold by Motorola, may display 12 characters per line. As such, since the capacity of the liquid crystal display is limited, the length of wireless call information that can be displayed on the liquid crystal display is also limited.

Therefore, if wireless call information having a length less than the capacity of the liquid crystal display is received, the wireless call information will be displayed on one screen of the liquid crystal display. However, when wireless call information having a length greater than the capacity of the liquid crystal display is received, all the wireless call information cannot be displayed on one screen of the liquid crystal display, so a separate process is required.

1A, 1B, and 2 are diagrams for explaining a conventional technique of displaying wireless call information (more specifically, a received message) when wireless call information having a length greater than that of a liquid crystal display is received.

Referring to FIGS. 1A, 1B, and 2, since the content of the message left by the caller is larger than the capacity of the LCD, the message is divided into two pages and displayed on the LCD. At this time, before the message is displayed or after the message is displayed, the reception time of the radio call signal is displayed, which is to distinguish from the previously received message or the next received message. Accordingly, the subscriber of the radio call receiver can distinguish each message from the radio call signal reception time displayed at the beginning or the end of the message even when a large number of messages are left to the subscriber.

Referring to FIG. 2 again, while the message left by the caller larger than the capacity of the LCD is continuously displayed, an icon of “▶” is displayed in the upper right part of the LCD, indicating that the message left by the caller is continuous. will be. The technique of indicating as a specific sign that the message left by the caller as a sequence is disclosed under the title "DISPLAY RADIO PAGING RECEIVER FOR VARIABLE LENGTH MESSAGES", filed after being filed by NEC in Japan. . Accordingly, the subscriber of the radio call receiver can know that the received messages are continuous.

However, according to the above method, when the length of the continuous message is large, there is a disadvantage in that an icon indicating that the continuous message is displayed on the screen of the liquid crystal display is displayed each time. In addition, the indication of the reception time of the radio call signal allows the identification of the next received message or the previously received message, but if the subscriber fails to properly confirm the reception time of the radio call signal, the previously received message or the next The disadvantage is that it is indistinguishable from the received message.

It is therefore an object of the present invention to provide a method for displaying a message continuously received at a radio call receiver.

Another object of the present invention is to provide a method for displaying a message having a length greater than that of a liquid crystal display in a wireless page receiver.

It is another object of the present invention to provide a method for simplifying the processing operation when displaying consecutively received messages in a radio call receiver.

It is still another object of the present invention to provide a method in which a subscriber can more effectively check a received message at a radio call receiver.

In order to achieve the above object, the present invention sequentially divides a received message into page units that can be displayed on a liquid crystal display, sequentially displays the message, and then displays a preset character indicating that the received message is the last and the time at which the received message is received. Suggest ways to display together. At this time, the character is displayed while blinking in a reversed form.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, the terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or chip designer, and the definitions should be made based on the contents throughout the present specification.

3A and 3B are diagrams for explaining an operation of displaying a continuous message on a liquid crystal display in page units according to the present invention. In this case, the continuous message means a message having a length larger than a capacity that can be displayed on the liquid crystal display. The PAGE means a reception message displayed on one screen of the liquid crystal display.

Referring to FIGS. 3A and 3B, the present invention divides a continuous message into pages on a liquid crystal display and sequentially displays the message, and then displays a preset character (END) indicating that the received message is the last and the time at which the received message is received. (11:28 am on August 13). At this time, the character is displayed in the reversed form and is displayed while the lighting and disappearing are repeated as shown in Figure 3b. Accordingly, the subscriber of the radio call receiver can more easily check the end of the continuous message.

4 is a diagram illustrating a configuration of a radio call receiver for performing an operation of displaying a continuous message according to the present invention.

In FIG. 4, the radio unit 110 receives a radio call signal through an antenna AT and performs functions of frequency conversion, demodulation, and waveform shaping. The output of the radio unit 110 is radio call information converted into digital data and is applied to the decoder 120. The decoder 120 sets an operation mode of the radio call receiver by decoding the applied data. That is, in the idle mode, the decoder 120 controls the operation power supplied to the battery 130 by controlling the switch 140 at regular intervals to detect preamble data. In addition, the decoder 120 detects word sync data and set frame data (address codeword + message codeword) in batch mode. The detected frame data is decoded, converted into the original data form, and output.

The memory 160 stores magnetic (unique) address and frame information assigned to the radio call receiver, and also stores a caller's message processed by the microcontroller 150. The key input unit 170 is for the interface between the radio call receiver and the user. The key input unit 170 is a function switch indicating various operation modes of the radio call receiver, a message confirmation of the caller and an operation mode selected by the function switch. It is implemented with two or three switches, such as a switch for.

The micro controller 150 receives the decoded data output from the decoder 120 to generate an alarm control signal and a display control signal to control the overall operation of the radio call receiver. Herein, the microcontroller 150 compares the data converted and output by the decoder 120 with the magnetic address stored in the memory 160 and generates an alarm control signal when the wireless call signal is analyzed to be information related to the magnetic. In addition, the micro-controller 150 performs an operation of generating a display control signal so that the received caller's message can be displayed on the display unit 180 and storing the message in the memory 160.

The display unit 180 is for displaying a caller's message and status information of the wireless call receiver. The display unit 180 is usually implemented by a liquid crystal display (LCD). The driver 182 drives the display unit 180 according to the display control signal generated by the microcontroller 150 to display the message of the caller and the status information of the radio call receiver on the display unit 180. The typical caller's message could be the caller's phone number.

The alarm unit 190 may be implemented as a speaker or a motor, and may be a tone signal or a vibration signal for notifying that the driver 192 is called by the alarm control signal output from the microcontroller 150. Raise an alarm. If the alarm unit 190 is implemented as a speaker, the tone signal will be transmitted to the external user through the speaker, and if implemented as a motor, the motor will be driven by the vibration signal. Accordingly, the user will recognize that the received wireless call signal is related to the information, that is, the call has been made.

5 is a flowchart illustrating a process of displaying a continuous message on a liquid crystal display in units of pages according to the present invention.

Now, assuming that the caller enters a call number of the radio call receiver having the configuration as shown in FIG. 4 and then leaves a continuous message such as "00112233445566778899", the radio call signal according to this is transmitted via the antenna AT of FIG. Will be received at part 110. When the wireless call signal is received in step 501 of FIG. 5, the wireless unit 110 outputs digital data by frequency converting, demodulating, and waveform-shaping the received wireless call signal, and the decoder 120 decodes the output digital data. The decoded data is applied to the microcontroller 150. In operation 502, the microcontroller 150 receives the decoded data and analyzes the received radio call signal. If it is determined in step 503 that the magnetic address is detected during the analysis operation, the microcontroller 150 performs the operation of displaying a received message in steps 504 to 510 since the received wireless call signal is call information related to itself. do.

In operation 504, the microcontroller 150 determines whether the frame length of the received message is greater than or not greater than the capacity that can be displayed on one screen of the liquid crystal display (LCD). If determined to be large, the microcontroller 150 sequentially displays the received message on the display unit 180 in page units in step 506. This display operation is performed until it is determined in step 507 that the message of the last page is displayed. When it is determined that the message of the last page is displayed, the microcontroller 150 displays the character indicating the last page (inverse of END) on the display unit 180 and receives the wireless call signal in step 508. Display the time of day (August 13, 11:28 am, "8-13 11-28A").

If it is determined in step 504 that the frame length of the received message is not greater than the capacity of the LCD, the microcontroller 150 displays the received message on the display unit 180 in step 509 and then displays the time when the wireless call signal was received in step 510. Display.

As described above, the present invention displays the message of the last page when the continuous message is received and displays the message indicating the fact with the time of receiving the message while flashing in reverse phase. Accordingly, the subscriber can more effectively distinguish the end of the continuous message. In addition, the present invention has the advantage that it does not have to be processed so that the icon is displayed on every screen on the liquid crystal display.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
