Data management device and method of wireless pager using computer

The present invention relates to a data management apparatus and method for a pager, and more particularly, to a data management apparatus and method for a pager using a computer that can control data and variables of the pager by a computer.

1 is a block diagram of a conventional pager.

Hereinafter, the configuration will be described with reference to FIG. 1. First, the controller 10 controls the overall operation of the radio call reception. The control unit 10 may be implemented as a one chip processor, and has a built-in universal asynchronous receiver / transmitter (UART). The first memory 20 stores data generated during the control of the controller 10. The key input unit 30 includes a lead key and a function key, and selects a plurality of functions by the combination of the keys. The RF receiver 50 receives a radio signal received through an antenna, filters the radio signal, converts the radio signal into a POCSAG code form, and outputs the converted radio signal. The decoder 60 restores the original data from the bread code and performs error detection correction. The display unit 40 displays the received data and displays the function selected by the key input unit 30.

Figure 5a shows a memory map of a conventional pager main message variable.

To illustrate this, the main message determines the overall operation of the pager. The main message has data receiving, key checking, key processing, time processing, and audio processing routines, and the routine is executed depending on whether the corresponding bit is set. For example, if the data receive bit is set, the program processes the received data and stores it in the corresponding first memory area and informs the user that the message has been received. In addition, when the user presses a key, the key processing routine is executed.

The wireless pager has evolved from a simple tone-only wireless pager to a wireless pager that can only display numbers and a textual display pager that can express characters. The current wireless pager is a high-speed wireless call service is introduced, which can be applied to a variety of information receivers, and has been developed to receive a large amount of information.

However, although the pager can receive a large amount of data, there is a problem in that a plurality of keys must be pressed in order to view a large amount of information.

Accordingly, an object of the present invention is to provide a data management method of a wireless pager using a computer that can read or manage the information stored in the wireless pager by communicating with the computer.

2 is a diagram illustrating a connection between a computer and a wireless pager for data management of a wireless pager using a computer according to an embodiment of the present invention.

Hereinafter, referring to FIG. 2, reference numeral 100 denotes a radio pager and 200 denotes a computer. The pager 100 and the computer 200 are connected by RS232C.

The pager 100 includes a control unit 10, a first memory 20, a key input unit 30, a display unit 40, an RF unit 50, a decoder 60, and a first connection unit 70. . The controller 10 is a general-purpose asynchronous transceiver and includes an asynchronous communication unit 12 for connecting a word of a parallel controller or a data terminal to an ordered bit communication network. The asynchronous communication unit 12 has a transmitting terminal Tx, a receiving terminal Rx, and a ground terminal GND. The first connection unit 70 connects the asynchronous communication unit 12 and the computer 200. The first connector 70 may be implemented as a jack.

The computer 200 transmits and receives data to and from the known central processing unit 110, the monitor 120, the keyboard 130, the second memory 150, and the wireless pager 100 applied to the present invention. A second connection unit 140 and a pager data management program according to the present invention are stored, and the second memory 150 stores data received through RS232C by executing the program. The second connection unit 140 uses a serial port of a computer, which is connected to the asynchronous communication unit 12 through the first connection unit 70 which is the general-purpose asynchronous transceiver through RS232C.

Referring to the connection between the asynchronous communication unit 12 and the second connection unit 140 through the first connection unit 70, the receiving terminal (Rx) of the asynchronous communication unit 12 and the transmission terminal (Tx) of the computer is connected. In addition, the transmission terminal Tx of the asynchronous communication unit 12 is connected to the reception terminal Rx of the computer, and the ground GND is connected to the ground of the second connection unit 140. This indicates asynchronous communication. Both the pager 100 and the computer 200 should use an asynchronous communication method. In addition, it is necessary to promise in advance how many bits a byte is, and how many bits are used for a stop bit.

3 is a flowchart illustrating a data management method of a wireless pager using a computer according to an embodiment of the present invention, and FIG. 4 is a flowchart illustrating an operation of a wireless pager by control of an external device according to an embodiment of the present invention.

Hereinafter, a data management method of a wireless pager using a computer will be described with reference to FIGS. 3 and 4. First, the computer 200 receives a predetermined input from the keyboard 130, executes the pager data management program stored in the second memory 150, and displays the initial screen on the monitor 120. When the initial screen is displayed, the CPU 110 checks whether a password has been input from the keyboard 130 in step 300. When the password is input in step 300, the central processing unit 110 transmits the password to the wireless pager 100 through the second connection unit 140 in step 301.

When the first connection unit 70 of the pager 100 and the second connection unit 140 of the computer 200 are connected, the control unit 10 of the pager 100 checks whether a password has been received in step 400. When the password is received in step 400, in step 401, the controller 10 checks whether the received password is the same as a preset password. If the received password is the same as the preset password, the controller 10 proceeds to step 402, and if not the same, ends. If the password is authenticated in step 401, in step 402, the control unit 10 transmits a response signal on the RS232C through the second connection unit 140.

After the step 301, the central processing unit 110 of the computer 200 checks whether a response signal has been received in step 302. When receiving the response signal transmitted from the pager 100, the CPU 110 proceeds to step 303 and transmits a Rx Read signal through the second connector 140.

After the step 402, the control unit 10 of the pager 100 checks whether the reception lead signal is input in step 403. When the reception lead signal is received from the computer 200, the controller 10 transmits the reception read response signal through the first connector 70. After transmitting the reception read response signal, the controller 10 proceeds to step 405 and transmits a message pointer table and data through the first connection unit 70 on the RS232C. The message pointer table is an area in which addresses indicating which messages are stored in the first memory 20 are collected.

After the step 303, the central processing unit 110 of the computer 200 checks whether the reception lead response signal is received in step 304. When the reception response signal transmitted in step 404 from the control unit 10 of the pager 100 is received in step 304, the CPU 110 prepares to receive data. When data is transmitted from step 405 of FIG. 4, the CPU 110 proceeds to step 305 and stores the received data in the second memory 150. When the data is received and starts to be stored in the second memory 150, the central processing unit 110 proceeds to step 306 to check whether the data reception is finished, and when the reception ends, the control proceeds to step 307 to monitor the received data. Display on 120.

5B is a memory map diagram of a pager main message variable according to an embodiment of the present invention.

In order to implement the present invention, a serial processing variable should be added to the above-mentioned main message variable of 5a. For example, when a key operation is performed, the pager 100 refers to the following variables when a key is input.

The first is a key value (Key_Value) referring to which key, and the second is a mode variable referring to which mode. The key processing of the pager is defined by various operations depending on the kit value and the variable value of the mode. Therefore, when these variable values are set using the computer 200, the pager operates by the set variables. When the variable value inside the pager is changed to the desired value using the communication line, the pager operates the program by the set variable value.

As described above, the present invention has an advantage that a large amount of data can be quickly confirmed through a few key operations through a computer.
