The present invention is a wireless pager. The present invention relates to a control method of a wireless pager having a message hiding function to prevent others from viewing the received message arbitrarily.

In general, the wireless pager used to call a specific person is increasing in popularity, and its use is also diversified. Therefore, there is a case where it is not desirable to disclose the message received through the pager to others. In the conventional pager, if the user presses the display switch, the received message is displayed on the display and unfavorably causes the user to be disadvantaged. there was.

Accordingly, the present invention has been made to solve the above problems, if the reception is determined that the user of the message needs to set the hiding function so that the corresponding message is not displayed on the display by the display switch by a simple operation of the user, and also the user The password of the wireless pager with the message hiding function prevents the user from being disadvantaged due to the exposure of the message by disabling the hiding function so that the received message can be displayed on the display unit. Its purpose is to provide a control method.

In order to achieve the above object, the present invention provides a hiding function to the received message, or stored in the internal memory of the decryption unit, and if there is a key input for displaying the received message with the hiding function, the decryption unit is a hidden function. And the first step of determining whether it is set. A second step of checking whether there is a received message stored in an internal memory if the hiding function is not set in the first step; A third step of, if there is a received message stored in the internal memory in the second step, the decrypting unit stores the password input by the user in the internal memory and gives a received function to the received message; If the hide function is set in the first step of life, the decryption unit determines whether the password entered by the user is the same as the password stored in the internal memory. A first step of determining whether the decryption unit has a hiding function if there is a key input. A second step of checking whether there is a received message stored in an internal memory if the hiding function is not set in the first step; A third step of, if there is a received message stored in the internal memory in the second step, the decrypting unit stores the password input by the user in the internal memory and gives a received function to the received message; If the hiding function is set in the first step of life, the decryption unit determines whether the password entered by the user is the same as the password stored in the internal memory, and the password input by the user in the fourth step is stored in the internal memory. If the password is the same as the stored password, it is characterized in that it comprises a fifth step of releasing the hidden function attached to the received message stored in the internal memory and displaying the received message on the display unit according to the operation of the display switch.

Below. A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a wireless pager to which the present invention is applied, and utilizes the structure of a general pager as it is.

As shown in the figure, the radio wave received through the antenna is demodulated at the receiver to make a logic level, which is input to the decoder. Accordingly. The decryption unit compares the code address data stored in the code memory with the logic level input from the receiver to determine whether appropriate call data is input.

When it is determined that the appropriate call data has been entered, the decryption unit immediately displays the received telephone number message on the display unit, and also stores the received telephone number message in the internal memory of the decryption unit, and also activates the driving unit to activate the vibrator set by the mode switch. Or trigger an alarm to notify the user that a message has been received.

The present invention provides the same function as the message suppression switch by additionally installing a suppression switch for setting and releasing the suppression function of the message received in the general pager configured as described above, or by combining a mode switch or a display switch mounted on the pager. You can also get

2 is a flowchart illustrating a method of surface receiving a message stored in a memory of a conventional pager to aid in understanding the present invention.

When the user presses the display switch, the decryption unit detects this and checks whether a reception message is specified in the decryption unit's internal memory. If there is no stored reception message, the decryption unit returns to the initial state. If there are received messages stored in the memory, this message is displayed on the display.

Therefore, if only the display switch is pressed, anyone can immediately see the contents of the message stored in the pager as described above, and there is no security at all.

therefore. The present invention provides a message hiding function to the wireless pager as shown in FIG. 3 in order to solve the above-mentioned lack of security of the conventional pager.

3 is a flowchart illustrating a method of controlling a pager having a message hiding function according to the present invention. When a message is received through an antenna, a vibrator or an alarm mounted on the pager is activated to notify the user of the message. . Accordingly, the user looks at the message displayed on the display unit.

At this time, if the user determines that the security of the received message is unnecessary and is left as it is, the received message is stored in the internal memory of the decryption unit according to a conventional method, and when the display switch is pressed, everyone can see it.

On the other hand, if the received message is not desired to be exposed to others, when the user presses the hide switch, the decryption unit stores the received message in the decryption unit's internal memory once, and checks whether the hide function is turned on according to the input of the hide switch. To judge.

If the hide function is not turned on. The decryption unit checks to see if there are any messages stored in internal memory. At this time, since the message just received is stored in the internal memory of the decryption unit, the decryption unit waits for the user to enter a password.

However, since the paging machine does not have enough space for installing the keypad, the present invention allows the input of numeric or alphabetic passwords by appropriately combining the existing mode switch and display switch.

For example, when the display switch is pressed while the mode switch is pressed, the display enters the password entry mode and a number appears on the display unit. The number displayed on the display unit continuously increases from 0 to 9 at a predetermined time interval. Therefore, if the user releases the display switch when the desired number appears on the display unit, one password number is input to the decryption unit, and several passwords can be input by repeating the above process. After that, release the mode switch and display switch at the same time to complete the password input.

When the input of the password is completed as described above, the decryption unit stores the input password in the internal memory, and then through the internal flag register, etc. that the hiding function is turned on and then automatically stops.

On the other hand, in the state that the hiding function is turned on as described above, if the user sees the message of the hidden state of the received message, the user can operate the hide switch again.

That is, when the user operates the hiding switch, the decryption unit recognizes this and checks whether the hiding function is turned on.

Since the flag register inside the decryption section is set to indicate that the hiding function is turned on, the decryption section prompts the user to input a password through the display section.

Therefore, when the user inputs the password in the same manner as described above, the decryption unit checks whether the input password and the password previously stored in the memory are the same, and immediately hides the entered password and the password previously stored in the memory. This function releases the message and displays a message on the display that was given a hidden function in response to a user's display switch operation.

On the other hand, when someone other than the user wants to see the message to which the hiding function is given, the display of the message to which the hiding function is given is denied by the decryption unit, which will be described with reference to the flowchart of FIG.

As shown in the figure. When the display switch is pressed, the decryption unit checks whether there is a message stored in the internal memory, and if there is a stored message, determines whether a hiding function is provided. The decryption unit stops the operation if the hidden function is given to the stored message, and displays the message if the hidden function is not provided to the stored message.

therefore. If you don't know the password, you won't be able to see any messages that are hidden, so you can prevent others from being compromised.

Meanwhile, in the above-described example, the case in which the password is composed of sequential order has been described. However, in the present invention, a password of alphabetic characters may be used instead of numbers. In other words. Pressing the display switch while pressing the mode switch enters the password input mode, and the Golbe and Bet letters appear on the display unit. The alphabet letters continue to increase from A to Z at a predetermined time interval. Therefore, when a problem desired by the user appears on the display unit, when the display switch is released, one password character is input to the decryption unit, and several characters can be input by repeating the above process. In addition, if the mode switch and the display switch are released at the same time after the password is input, the input of the alphabetic password is completed.

In addition, in the present invention, a separate switch may be additionally installed and installed in the decryption unit for inputting a password, or a password may be input by combining a switch other than a display switch or a mode switch.

Also. In the above example, the induction switch is additionally wired to the readout unit. However, without additionally setting the induction switch, for example, pressing the installed switch for 5 seconds or more continuously, the induction unit presses the induction switch described above. You can also do the same thing.

In addition, the frequent change of the password may give the user a psychological burden due to memorization, so the password may be stored in advance in the internal memory of the decryption unit from the time of shipment of the product.

That is, as shown in FIG. 5, when the user presses the hide switch in the state in which the message is received, the hide function is applied to the received message, and the user presses the hide switch to view the message to which the hide function is applied, and then presses the password. Upon input, the decryption unit determines whether the password is canceled by determining whether the input password is equal to the password stored in the internal memory.

In this case, if the user knows only one password, there is no need to enter the password every time, and it is not only easy to use, but also one of the passwords can be used to unlock the hidden function. On the other hand, there is an advantage that it is easy to use because there is no burden. On the other hand, it is impossible to change the password.

Therefore, as shown in FIG. 6, the decryption unit has two passwords for setting and releasing the hiding function so that a user or a predetermined password is input to activate the hiding function, and then the other is released for releasing the hiding function. When the password is input, the security of the password can be secured to some extent, and the user only needs to know two passwords, thereby reducing the burden of memorization due to the password change.

As described above, the present invention can selectively give a hidden function to a message requiring security among the received messages, and thus has a useful effect of preventing a user's disadvantage that may occur due to exposure of information to others.
