Abstract

According to the present invention, when displaying a message received by a wireless call receiver, unnecessary data included in the received message data can be deleted and displayed.

To do this, when a message is received, the received message is stored in the receiving buffer. The data constituting the received message are then examined for blank data received since the last valid data. At this time, if there is no blank data after the last valid data, all data of the received message is stored and displayed as valid data. If there is blank data, the blank data received after the last valid data is deleted, edited, stored and displayed.

Therefore, the wireless call receiver of the present invention does not store and display unnecessary blank data included in a message, thereby improving the efficiency of the memory and the display unit.

The present invention relates to a message display method of a radio page receiver, and more particularly, to a method of editing and displaying unnecessary data by analyzing data of a message received from a radio page receiver.

In general, a small paging receiver generates an alarm signal in response to received paging information, and displays a message transmitted by the caller together with the alarm signal. At this time, the form of paging information received by the radio call receiver has a specific code form. Here, it is assumed that the POCSAG code (Post Office Code Standardization Advisory Group Code). The POCSAG code consists of eight frames in one batch, and each frame includes an address code word representing a unique address of the radio page receiver and a message code word containing information generated at the caller. code word). Here, the message codeword is composed of character data, numeric data, blank data and the like.

1 is a block diagram of a radio call receiver, which includes a receiver 10 for converting received RF (Radio Frequency) signals into digital data by frequency conversion, demodulation, and waveform shaping, and a memory storing unique addresses of the radio call receiver. 40 and a RAM 21 for temporarily storing data, the data received from the receiving unit 10 is analyzed and compared with the unique address information, and generates the same address temporary alarm signal. A control unit 20 for controlling to display a message, a display unit 30 for displaying message information received under the control of the control unit 20, and a buzzer 60 when the control unit 20 generates an alarm signal. It is composed of an alarm driver 50 generated by the alarm sound.

Referring to the operation of the radio call receiver having the above configuration, first, the caller requesting the paging function first dials the number of the radio call receiver, and then generates message information which is information of the call subscriber. At this time, the message information may be a phone number or a unique number or text information promised. The paging information generated as described above is converted into an RF signal by a paging system and propagated to the air, and the radio call receivers are turned on at a predetermined period to receive the RF signal propagated as described above.

The receiver 10 of the radio call receivers amplifies the received weak RF signal, converts the falling frequency, demodulates it back to the original signal, waveform-forms the demodulated analog signal into digital data, and applies it to the controller 20. do.

The control unit 20 is a one chip microprocessor unit, and includes a ROM storing a program therein and a RAM 21 for temporarily storing data generated during program execution. As the microprocessor having the above function, the HD40L4818 series series manufactured and sold by Hitachi of Japan can be used. The controller 20 accesses the magnetic address data stored in the memory 40 when the power is turned on, and stores the address data in a specific area of the RAM 21. When the data is received from the receiver 10, the controller 20 compares the address codeword of the received data with the specific address of the RAM 21 and has the same address as a result of the comparison. Recognizes that the received paging information is its paging information, outputs an alarm signal, and outputs the received message codeword (hereinafter referred to as message) as display data.

Then, the alarm driver 50 drives the buzzer 60 to generate an alarm sound, and the display unit 30 displays a message output from the controller 20. In this case, the paging alarm method is widely known as a method of displaying the alarm using a vibrator, a lamp, and the like, in addition to a method of generating an alarm sound through the buzzer 60 as described above. In addition, the display unit 30 may use an LCD, and the memory 40 may use an EEPROM.

However, when the control unit 20 outputs the display data to the display unit 30, the receiver 20 outputs the message as it is. As a result, even if unnecessary data is included in a received message, all received information is displayed. That is, even if the received message is blank data, there is a problem of displaying it as it is.

Herein, a conventional operation process of displaying a received message on the assumption that the message has been received will be described.

Page 2 745-0084 ---- 23

Page 3 745-0084 ---------

Page 4 7 --- 0084 ---------

Although the messages of page 1 and page 2 may be displayed as received data, the messages of page 3 and page 4 may be edited, stored, and displayed. This is because blank data received after the last valid data may be removed because it is information having little meaning. However, in the conventional wireless call receiver, the message information received as described above is stored in the RAM 21 and controlled to be displayed on the display unit 30 as it is. Therefore, unnecessary data stored in the RAM 21 are stored, and the display unit 30 has a problem in that the display operation can be performed several times in order to display unnecessary data included in the message.

Accordingly, an object of the present invention is to provide a method that can remove and display unnecessary data after analyzing data of a message received from a wireless call receiver.

It is still another object of the present invention to provide a method of deleting and displaying blank data received after the last valid data among data constituting a message when a message is received in a radio call receiver.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same parts in the figures represent the same reference signs wherever possible.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, such as the integrated circuit name and telephone number of each component. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details.

In addition, among the terms used below, the blank data includes space data and dash data, and the valid data includes numeric data and character data, and before the last character data or numeric data of the received message. It contains the received blank data, the last valid data being either character data or numeric data.

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

The configuration of the bus call receiver for carrying out the present invention is the same as that of FIG. 1, and the reference numerals are the same.

4 shows the configuration of the reception buffer and the message buffer assigned to the RAM 21 in the control unit 20. As shown in FIG. 4A to 4A are reception buffers in which the control unit 20 stores data of a message received through the reception unit 10. 4B is a message buffer for storing the edited message in page units, and the control unit 20 accesses the edit message of the message buffer corresponding to the number of presses of a read key in page units. It outputs to the display part 30.

Therefore, the message display device configuration of the present invention according to the configuration of FIGS. 1 and 4 includes a lead key, a reception buffer for storing a message received in an area allocated to the RAM 21, and a message of the reception buffer. An area allocated to the RAM 21 and a control unit 20 for analyzing the state of the data constituting the message and deleting and editing blank data and generating a message selection signal corresponding to the number of times the lead key is pressed. A message buffer for storing a message in which blank data has been edited under the control of the control unit 20 and outputting an edit message corresponding to the message selection signal as display data, and a display unit for displaying an edit message output from the message buffer ( It can be seen that it consists of 30).

2 is a flowchart of editing blank data among received data in a wireless call receiver according to an embodiment of the present invention. The received message is stored in a receiving buffer, and the message stored in the receiving buffer is accessed to access the data of the message. After analyzing the blank data after the last protected data, the blank data is deleted, edited and stored in the message buffer, and the edit message stored in the message buffer is displayed on the display unit 30.

FIG. 3 is a flowchart of another embodiment showing a process of analyzing and displaying a received message as shown in FIG. 2, storing the received message in a receiving buffer, analyzing all data states of the message, In the case of valid data, the data is stored in the message buffer. Second, if all data are blank data, the data is deleted. Third, in the presence of valid data and blank data, the blank data received after the last valid data is deleted. After that, the rest of the data is stored in the message buffer, and then the edit message of the message buffer corresponding to the number of occurrences of the read key is displayed.

The present invention will be described in detail with reference to the flowcharts of FIGS. 2 and 3 and the memory map of FIG. 4 based on the configuration of the radio call receiver of FIG.

First, when the receiver 10 outputs the received wireless call data, the controller 20 compares and analyzes the address information received from the output of the receiver 10 and the magnetic address information to check whether the received data is magnetic data. do. At this time, if the address of the received data is the same as its own address, the controller 20 sequentially stores the message of the received data in the receiving buffer of the allocated RAM 21 as shown in FIG. 4A. The control unit 201 checks whether all the message information has been received in step 201, and if the message is being received, repeats the above message receiving and storing process.

In this case, when the reception of the message is completed in step 201, the control unit 20 accesses the message information stored in the reception buffer area as shown in FIG. 4A, and then all data of the message received in step 202 are valid. Check for data. Here, valid data means character data, numeric data and character data of 0 to 9, and blank data existing between the numeric or character data as described above. Here, the blank data includes both desi data and space data. Therefore, in step 202, the message stored in the reception buffer is analyzed to check whether the stored data are valid data.

In this case, there are two methods for analyzing whether the data constituting the message are valid data. The first method is to check the data of the received message from the front in the order in which it was received. In this case, in order to break the validity of each data constituting the message, first check whether the corresponding data are valid data. In other words, it is to check whether the data currently being checked is alphabetic data corresponding to A-Z or numeric data corresponding to 0-9. If it is character data or numeric data, it is determined that the data is valid data. However, if the data currently being examined is not character data or numeric data, it becomes blank data. If such blank data is followed, it is checked whether there is character data or character data in the received data. At this time, if there is character data or numeric data after the blank data, it is regarded as valid data. However, if there is no character data or numeric data after the blank data, the blank data is regarded as unnecessary data. Thus, the last valid data in the data composing the received message is either character data or numeric data.

The editing process of the blank data will be described with reference to the messages stored in the reception buffer as shown in FIG. When the message is received as 745-0084 ----- as shown in (4A3) of the reception buffer, 745 is composed of numeric data and thus all are considered valid data. In the case of-, which is the first blank data, it is determined according to the data state that follows. Also, in case of 84, all data are numeric data, so they are regarded as valid data. However, in the case of the second to sixth blank data ----, since there is no numeric data or character data later, this is regarded as unnecessary data. In other words, since the last valid data is 4, all of the sixth blank data in the second blank data located after the last valid data 4 are regarded as unnecessary data.

The second method is to check the data of the received message in the reverse order of the received order. This checks whether the last received data is character data or numeric data. If the last data is character data or numeric data, the receiving buffer All the data of the message stored in the system are considered valid data. However, if the last data is blank data, the last valid data is searched. If the last valid data is searched, the blank data received after the last valid data is regarded as unnecessary data.

The editing process of the blank data will be described with reference to the messages stored in the reception buffer as shown in FIG. When the received message is received at 745-0084 such as (4A2), since the last data is numeric data of 4, all received data information is regarded as valid data information. That is, since the last data constituting the message is the last valid data of 4, all the data of the received message is the valid data. However, if the data constituting the received message are 745-0084 ---- such as (4A3), the last data is blank data, so the state of the data is checked as the last valid data is moved. In this case, since the last valid data is 4, ---- is regarded as unnecessary data.

If the blank data exists after the last valid data of the message by analyzing the message received in step 202 as described above, in step 203, the blank data existing after the last valid data is deleted and edited, and (204) In step), the edited message is stored in a message buffer as shown in FIG. 4B, and the display unit 30 is controlled to display and edit the edited message as described above. Therefore, in the message display process, since the display is performed in a state where unnecessary blank data is removed, the size of the display unit 30 can be used very efficiently.

If blank data does not exist after the last valid data of the message received in step 202, all data of the message received in step 204 is stored in the message buffer as shown in FIG. 4B, and the display unit ( 30) to display the received message information. In this case, since there is no unnecessary data information in the message, all received data information is displayed.

The process of another embodiment will be described in detail with reference to FIGS. 3 and 4.

The controller 20 stores the received message information in a reception buffer as shown in FIG. 4A. When the controller 20 detects the reception of the message in step 301, it checks whether blank data exists in the received message in step 302. If there is no blank data among the first received messages, all the data constituting the received message are valid data. Therefore, in step 308, the controller 20 stores all data of the received message in the message buffer as shown in FIG. 4B. The display unit 30 displays all data of the received message. That is, when 7450084 is received as in (4A1), 7450084 is stored and displayed as it is without editing as in (4B1).

If the second received message is all blank data, the controller 20 recognizes this in step 303, deletes all blank data received in step 304, and displays the display unit 30 in step 305. Indicates that messages received by control are blank. That is, when all received messages are received as blank data without valid data, the blank data are all deleted and edited by performing steps 303 to 305, which are stored in the message buffer as shown in FIG. 4B. There is no data and it is not displayed on the display section 30 either. That is, if --------- is received as a message as shown in (4A5), the blank data, which is the dec data, are deleted and edited and the display process is performed. Do not save them.

If the third received message contains blank data but does not exist after the last valid data, the control unit 20 recognizes this in step 306 and blanks the data of the message received in step 308. Instead of deleting and editing the data, all the data received in the message buffer as shown in Fig. 4B is stored and displayed on the display section 30 at the same time. That is, since the above process includes blank data information in the received message but exists only between valid data which is character data or numeric data, such blank data is regarded as valid data. This is valid as described above when 745-0084 is received as a message such as (4A2) in the receiving buffer having the configuration as shown in FIG. 4A, because the blank data information of-is present between the numeric data of 5 and 0. It is regarded as data. Since the blank data has not been received since the last valid data 4, all the data of the received message are stored in the message buffer as shown in (4B2). Display them.

If the blank message is included in the fourth received message and is present after the last valid data, the control unit 20 recognizes this in step 306, and the last valid message among the messages received in step 307. Thereafter, after deleting and editing the existing blank data, in step 308, the message edited as described above is stored in the message buffer as shown in FIG. 4B, and the message received in the edited form is displayed through the display unit 30. . In this case, since unnecessary messages are not displayed, the display function can be effectively performed even when the number of display data of the display unit 30 is small. That is, when 745-0084 ---- is received as a message (4A3), it is recognized that blank data information of ---- exists after 4, which is the last valid data. In this case, the controller 20 considers the blank data as unnecessary data information in step 306 and deletes it in step 307. However, blank data existing between 5 and 0 are considered valid data as described above and stored and labeled as 745-0084 as shown in (4B3). Also, in the case of message 7 --- 0084 ---- received as in (4A4), the same operation as in the fourth operation is performed, whereby 7-0084 is stored in the message buffer as in (4B4).

In addition, a wireless call receiver generally includes a lead key to perform a display function. That is, the controller 20 is connected to the lead key, and counts the number of times the lead key is pressed by the user, and then reads the message of the corresponding position from the message buffer as shown in FIG. 4b. Mark on. Accordingly, it can be seen that the edited message upon receiving the message is displayed on the display unit 30 at the same time as being stored in the message buffer of the RAM 21 and can be displayed again by the lead key.

As described above, the present invention uses the display unit and the memory efficiently by inspecting the data of the received message when receiving the message information in the wireless call receiver and deleting and storing the data if unnecessary data information exists. It can be effective.
