The present invention relates to a control method of a communication terminal, and more particularly, to a remote control method of a communication terminal for controlling the operation of the receiving terminal by using a minor number transmitted from the transmitting terminal.

As the use of portable communication terminals is becoming more common, terminals having various functions and designs have emerged. In particular, recent portable communication terminals have been implemented in a direction in which the role of a personal mobile communication device and an information processing device such as a personal information management device is further increased, and the implementation of various additional functions is implemented to satisfy such characteristics. Proposed to the terminal.

On the other hand, as the use of portable communication terminals has become commonplace, a situation in which the terminal is lost or difficult to determine the current location of the terminal has frequently occurred. In this case, the subscriber should make a stop request to the mobile communication provider in order to restrict the person who has acquired the terminal from using the mobile terminal arbitrarily. However, such a method can prevent a person who has acquired a terminal from using the terminal arbitrarily, but also restricts a method in which a person who loses the terminal can contact his or her lost terminal. Therefore, when the terminal is lost, the user loses the opportunity to simply find the lost terminal by calling his terminal and talking to the person who acquired the terminal.

Therefore, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is a communication that can control the function of its own communication terminal even when the communication terminal is located in a place other than the user's location To provide a remote control method of the terminal.

In order to achieve the above object, a remote control method of a communication terminal according to an embodiment of the present invention includes a sub-number including a remote control code for controlling a function of a receiving terminal in a transmitting terminal, together with a subscriber number. A first process of transmitting to a receiving terminal; A second step of parsing the minor number in the receiving terminal to determine whether a remote control code is set; As a result of the determination, if the remote control code is set, the operation of the receiving terminal is controlled according to the remote control function set in the sub-number. It is characterized by including.

Preferably, the minor number is an identifier for distinguishing between the subscriber number and the minor number, a remote control code indicating that a number given to the minor number is for remote control, and a control indicating a function to be remotely controlled. It includes an index and a delimiter for distinguishing each field constituting the minor number.

More preferably, the minor number further includes a password for checking whether the sender is a valid user. If the remote control code is set as a result of the determination of the second step, the minor number is determined according to the remote control function set in the minor number. And a fourth step of checking whether the sender is a valid user by analyzing a password before controlling the operation of the receiving terminal, and a fifth step of immediately ending the call if the sender is not a valid user. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In general, in order to make a call with a portable communication terminal, a reception number is basically input. The reception number is a national destination code, a subscriber number, and a subaddress as shown in FIG. Consists of

FIG. 1 is a diagram of a telephone number system assigned for transmitting / receiving a call in a portable communication terminal, and is an ISDN number system based on the E.164 standard supported by the NSAP number system. This configuration is based on the ISDN numbering system. This subnumber was used for the purpose of subdividing each telephone when several telephones were connected to one telephone number in the initial ISDN network. That is, it has been used to distinguish the final TE of subscribers subscribed to the ISDN network. However, in the present mobile communication, its form remains, but its use is not clearly distinguished.

Therefore, the present invention intends to control the communication terminal by using a minor number which is not currently used well.

FIG. 2 is a diagram schematically illustrating a configuration of a mobile communication terminal to which the present invention is applied. An RF (radio frequency) unit or a dual tone multi frequency (DTMF) unit implemented in a typical mobile communication terminal is a mobile communication terminal. It is an essential component in operation, but it is not directly related to the gist of the present invention, and drawings and description thereof will be omitted. However, it will be apparent that a mobile communication terminal actually implemented according to the present invention includes the above components as essential components.

Referring to the configuration and operation of the mobile communication terminal to which the present invention is applied with reference to FIG. 2, the central processing unit 10 controls the overall operation of the mobile communication terminal, a communication terminal using a minor number pattern according to the present invention Control the overall operation of the remote control function. In particular, the central processing unit 10 checks the presence or absence of a minor number, and if there is a minor number, determines whether it is for remote control and performs the corresponding operation. The central processing unit 10 is typically implemented to be used as a one chip microprocessor.

The key input unit 20 includes a keypad having a plurality of numeric keys and function keys, and is a user interface device that generates corresponding key data according to a key input from a user.

The display device 30 is a user interface device for displaying the overall state of the mobile communication terminal and inputted numbers and letters so that the user can know. The display device 30 is generally implemented as a liquid crystal display (LCD). The keyword related information input through the key input unit 20 is displayed under the control of the CPU 10.

The memory 40 is implemented as a volatile memory and a nonvolatile memory, and stores a program and initial service data that collectively controls the overall operation of the mobile communication terminal, a password for remote control, and data generated according to an operation. In addition, the buffer function performs a function of temporarily storing data to be processed and necessary data.

3 shows a configuration example of a minor number in FIG. 1 for remote control according to the present invention, and is a pattern seen from the transmitting side.

In FIG. 3, the first '/' is an identifier for distinguishing between a subscriber number and a minor number, and this identifier is a pattern used universally to distinguish between a subscriber number and a minor number in a wireless communication network.

Second, 'RC_code' is a remote control code indicating that the number given in the subnumber field is for remote control use.

Third, 'Password' is a password portion for determining whether the sender is a valid user, that is, the owner of the called terminal. This password is set by the user in the communication terminal to ensure uniqueness. The length of the password can be variable, for example, from 4 to 8 characters. This password is stored in a nonvolatile memory such as EEPROM and used for the password comparison process described later.

Fourth, 'Control_index' is for distinguishing a function that wants a remote control, it is possible to specify all the functions to control the communication terminal, the example is shown in Table 1 below. This is because the minor number can be up to 20 octets (40 digits).

The number of digits that can be assigned to the index is 20 octets (40 digits), so the number of digits can be assigned to the remote control function in addition to the functions shown in the example in Table 1 above. You can do For example, the current location of the communication terminal may be sent to the sender by a short message or e-mail.

Also, '*' between each field is a separator to distinguish between each field when analyzing minor number.

The preparation of the minor number pattern having the above configuration and the operation thereof are as follows.

When the sender enters the receiver's telephone number to start a telephone call, a subnumber pattern as shown in FIG. 3 is created and input together. For example, suppose RC_code: 10, Passwork: 12345678, Control_index: 3, and call 393297603477.

Enter '393297603477/10 * 12345678 * 3' and press the send button.

When the transmitting terminal inputs the minor number pattern together with the subscriber's subscriber number and transmits it, the receiving terminal receives the minor number together with the subscriber number.

4 is a flowchart illustrating a process of analyzing a number received at a receiving terminal and performing a corresponding operation according to the present invention.

Referring to FIG. 4, when a call is received by the receiving terminal (410), it is first determined whether a minor number exists (420). If it is determined that there is no minor number, operation 401 is performed like a normal call reception to notify the user of receiving a call (402), and if a minor number exists, the minor number is parsed (430). In the parsing process of the minor number (430), first check the existence of the remote control code (440), if it does not operate like a normal call (401, 402), and if it turns out to be a remote control code to analyze the password (450) Check if it is a user. If the analysis of the password 450 is not a valid user, the call is immediately terminated (403). If the user is a valid user, the control_index is checked (470). If the corresponding number is not the number corresponding to the function implemented in the terminal, the call is terminated (403).

As in the above example, when the number transmitted from the transmitting terminal is '393297603477/10 * 12345678 * 3', the receiving terminal sees '/' between the numbers and the subscriber number '393297603477' and the minor number pattern '10'. Note that * 12345678 * 3 'has been received. Then, the receiving terminal uses the subscriber number to check whether the number is stored in the phonebook and then parses the minor number. During the parsing process, first check the existence of the code '10' for remote control, and extract the password from the minor number to check whether the input of the remote control code is by a valid user. If the input password '12345678' matches the password for the remote control set by the user, the control_index is parsed to determine what function to control remotely. Action defined by parsing Control_index '3' For example, if the function of Control_index is defined as in Table 1 above, the short message is the text corresponding to '3', that is, the text defined by the number set by the user. Perform the function of sending to.

On the other hand, Figure 5 is a flow chart showing an example of a password setting process for remote control applied to the present invention.

Referring to FIG. 5, to set a password for remote control, first enter a password setting menu 501, enter an existing password (502), and then enter a new password to be changed (503). After entering a new password (503) and re-enter a new password (504) to confirm that the new password has been entered correctly. After re-entering the new password (504), it is determined whether the existing password is valid (505) and if it does not match the preset password by the user, it returns to the password setting menu (501) and resets the password setting operation for remote control from the beginning. Perform. If it is determined whether the existing password is valid (505) and matches the preset password, the password is changed to the new password input in step 503 and the password setting operation is completed (506). Although not shown in the drawing, in the process of determining whether the existing password is valid 505, if there is an input error of a password exceeding a predetermined number of times (for example, three times), the user may exit from the password setting menu.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible 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 determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention can control the communication terminal at a long distance by adding a function for remotely controlling the communication terminal to a sub-number, which is an existing area, and transmits a short message or e- You can also respond by mail. In addition, when the communication terminal is lost, the function of activating the lock device of the terminal may be given to the control_index or the mobile phone may be powered off when the mobile phone is not carried.

As such, the present invention can easily implement remote control without an additional module or service, and the number of digits can be assigned to the control index with 20 octets (40 digits). By giving remote control function, user can control desired from a long distance.

In addition, since the receiving terminal does not receive the call directly, there is an effect that the mobile phone can be controlled without paying the call fee.
