The present invention relates to a method for setting a password for remote control of an aerial terminal, and more particularly to a method for changing the number of digits of a password.

In general, an aerial terminal system that can be remotely controlled by a Dual Tone Multi-Frequency (DTMF) signal uses a password as a means of allowing remote control. However, the digits of the password of the aerial terminal system as described above are fixed. Therefore, the user must set the password according to the fixed digits when setting the password, so it is difficult to memorize or vary the password in various ways, resulting in inconvenience in use.

Accordingly, an object of the present invention is to provide a method for registering by setting the number of digits of a password variably within a specific range when setting a password for remote control in an aerial terminal.

Another object of the present invention is to provide a method for performing a remote control function by comparing a password and a receiving number that are variably registered in an aerial terminal.

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

1 is a block diagram of a public terminal for carrying out the present invention, and shows an example of the configuration of an answering machine. Looking at the configuration of the answering machine, the central processing unit 101 controls the overall operation of the answering machine. The key input unit 102 generates key commands and data of the auto answering device pressed by the user and applies them to the central processing unit 101.

The line interface unit 104 is connected to the public telephone network to interface voice signals and various signals between the answering machine and the public telephone network. The king sensing unit 105 is connected to the line interface unit 104, detects a ring signal outputting the line interface unit 104 and outputs the ring sensing signal to the central processing unit 101. The call path unit 106 is connected to the line interface unit 106, and the loop relay is switched under the control of the central processing unit 101 to process the call voice signal and various tone signals. A DTMF decoder 107 converts the DTMF signal received in connection with the call path unit 106 into digital data and outputs the digital signal to the CPU 101. The audio processor 108 processes the audio signal input and output connected to the call path 106 and the voice signal input / output unit. An outgling message (OGM) 109 is connected to the audio processor 108 and resists and reproduces the outgoing message under the control of the central processing unit 101.

An increasing message unit (TCM) 110 is connected to the audio processor 108 and stores and reproduces a voice signal received under the control of the CPU 101.

2 is a flowchart of a process of setting a password for remote control of an aerial terminal according to the present invention, and registers a password sequentially received through the key input unit 102 in a registration mode, wherein the password is valid if received within a maximum number of digits. Determine.

FIG. 3 is a flowchart showing a process of controlling using a password for remote control of an aerial terminal set as shown in FIG. 2, and is a flowchart when it is applied to an answering machine.

The present invention of FIG. 1 described above will be described in detail with reference to the flowcharts of FIGS. 2 and 3.

First, referring to Figure 2 looks at the registration process of the password for remote control. As described above, in the use of the password for remote control by the DTMF signal, the number of digits of the password can be variably used within a specific range in order to more conveniently and easily use the password. At this time, the password may be registered using a social security number or an anniversary, which the user may easily memorize. Since the password is performed in the registration mode, the central processing unit 101 checks the output key data of the key input unit 102 in step 201 to confirm whether a registration key is generated. At this time, if the registration key is received in step 201, it is checked whether numeric key data is received in step 202. If the numeric key data is not received in step 202, it is checked whether a predetermined time has elapsed in step 205. If the numeric key data is not received or another key data is received for a predetermined time elapses, in step 206, Error handling and returning password registration function.

However, if the numeric key data is received within a predetermined time in step (202), it is checked in step (203) whether the numeric key data currently received exceeds the maximum number of digits of the remote control password. This is to limit the number of digits for the remote control to be more than necessary. Therefore, if the received numeric key data exceeds the maximum number of digits in step (204), the beep is supplied to the user axis in excess of the number of digits, and the process returns to step (202) again to perform the remote control password registration process again.

At this time, if the received numeric key data does not exceed the maximum number of digits in step (203), it is checked whether a registration key is received in step (207), and the registration key restarts the mode of the aerial terminal to the registration mode in the first step. In the second, release the set registration mode. Accordingly, when the registration key is received in step 207, the remote control password is set as a password in step 208 by being set variably by the user within the maximum number of digits in steps 202 and 207. Finish the process.

Therefore, when registering a password for remote control, the registration mode is first set by the registration key, and then the numeric key data received with variable digits is checked.If the registration key is received again, the registration mode is canceled and the numeric key data received so far is encrypted. Register and exit. For example, if the maximum number of digits that can be registered is 6 digits, when the numeric key data of 6 digits or less is received, the corresponding number is registered as a password.

A process of performing the function of the remote control in the state of registering the variable password as described above will be described with reference to FIG.

First, when a ring signal is generated from the public telephone network and applied to the line interface unit 104, the ring detection unit 105 detects the ring signal and applies it to the central processing unit 101. At this time, the central processing unit 101 counts the number of rings received from the ring detecting unit 105 in step 301 and checks whether a ring signal is received more than a predetermined number of times. At this time, when the ring signal is received about 2 to 4 times in the state of the auto answer function is set, in step 302 to turn on the loop relay (loop relay) of the call path (106) to form a call path. In step 303, the sending message unit 109 is driven to start sending the sending message (response message). The response message is then output to the public telephone network through the audio processing unit 108, the call path unit 106 and the line interface unit 104.

After transmitting the response message, the CPU 101 checks the DTMF decoder 107 in step 304 to check whether the DTMF signal is received. At this time, when the DTMF signal is received from the public telephone network, it is applied to the DTMF decoder 107 through the line interface unit 104 and the call path unit 106, and the DTMF decoder 107 converts the received DTMF signal into a digital signal to generate a center signal. Output to the processing apparatus 101. Then, the central processing unit 101 compares the remote control password stored in the flow shown in FIG. 2 with the received digital data in step 307 and checks whether the two data are the same in step 308.

At this time, if it is determined that the same data in step (308), it is determined that the password for performing the remote control is input, and jumps to the mode for performing the remote control function in step 309, the remote control according to the received command Perform the function. At this time, the remote control function may perform a function of remotely listening to the recorded message from the outside, changing the response message, and setting and releasing the auto-response state. However, if it is not the same in the above step 308, the loop relay of the communication path unit 106 is disconnected to cut and terminate the communication path.

However, when the DTMF signal is not received until the time when the response message is sent out through steps 304 and 305, the central processing unit 101 transmits the message received from the counterpart in step 306 to the line interface unit. (104) Currency Department (106) Authorized to the message message unit 110 through the audio processor 108, and stores the message.

As described above, when setting the password for the remote control of the aerial terminal, the user can register the password with a number that is easy to memorize within a certain number of digits, and can give a sufficient number of digits.
