The present invention relates to an engineering mode operation for inputting operation information and parameter values to a mobile terminal. In particular, the engineering mode of a mobile terminal to enter the engineering mode since the primary key and the hidden key are input within a predetermined time after the operation power is applied. It relates to an operating device and a method.

The mobile communication terminal (MS) freely moves in a service area formed by the mobile communication base station (RAN), via a communication path established by monitoring, control and switching of the mobile switching center (MSC), It is a high-tech wireless communication device that instantly communicates with the desired party anytime, anywhere, and moves anywhere while carrying it directly by the individual.

Since the base station (RAN) forms a service area of limited size, since a plurality of base stations are continuously arranged at regular intervals and installed and operated, the base station (RAN) expands the service area, and the MSC is a mobile terminal by location registration. Identify which base station is located within the service area of the base station.

The portable terminal (MS) is built-in and records the operating information, such as electronic serial number (ESN: ELECTRONIC SERIAL NUMBER), manufacturing number, unique telephone number, model number, subscribed mobile communication service company information, and connected through a base station Since it is provided to the mobile switching center, the location is registered.

In order to record, modify, and change the operation information in the mobile terminal MS, the menu of the engineering mode must be entered. The engineering mode is also called the hidden mode. Enter by entering a separate hidden key signal consisting of 8 to 8 bits.

The mobile terminal (MS) is equipped with various additional services or additional functions (hereinafter, additional services) for usability and usability when not directly used for communication, and the additional service is developed and provided by a mobile terminal manufacturer. Such as, camera, Bluetooth, WLAN, radio, games, electronic calculator, calendar, clock, ringtone, phone book, schedule management, etc. The mobile communication service provider develops and provides, such as text messages, video messages , Online games, wireless Internet access, caller identification, and the like, and these additional services continue to be developed with new features added.

In order to systematically operate various additional services as described above, various operating parameters must be input to the corresponding registers of the mobile terminal.

As described above, the mobile terminal (MS) requires input of various operation information and parameters, and the operation information and parameters are inputted only in a state in which the mobile terminal is set to an engineering menu mode and can be modified and updated. If there is an error in the information input in the menu mode, the portable terminal cannot be used. Therefore, only an authorized technician or engineer should enter the engineering menu mode.

Therefore, there is a need to develop a technology that prevents the user from entering any case in the engineering menu mode of the portable terminal.

Hereinafter, an engineering mode operating method of a portable terminal according to the prior art will be described with reference to the accompanying drawings.

1 is a flowchart illustrating an engineering mode operating method of a portable terminal according to the prior art.

Referring to FIG. 1, the engineering mode operating method of the portable terminal according to the prior art will be described. The portable terminal MS determines whether to enter the engineering menu mode for inputting operation information and parameter values ( S10), if the determination is made to enter the engineering menu mode (S10), a hidden key (HIDDEN KEY) is input (S20).

In step S20, the portable terminal performs an authentication process for comparing whether the input hidden key information is the same as the embedded information (S30), and when the embedded information and the input hidden key information in the comparison authentication process coincide with each other. In order to enter the engineering menu mode, operation information and parameters are input and modified (S40).

The HIDDEN KEY entering the engineering menu mode is generally 4 bits to 8 bits, and includes a numeral from 0 to 9 and symbols of * and # for dialing of a mobile terminal.

The engineering menu mode does not appear in a menu for operating the mobile terminal, and is displayed only when the hidden key is input and authenticated.

Therefore, when a user accidentally enters a combination of numbers and * and # symbols by mischief and enters a hidden key, the user enters the engineering menu mode, and when the operation information and parameter values are modified or changed. However, there is a problem that the mobile terminal does not operate normally or causes a serious obstacle.

The present invention is to set the engineering menu mode operation enable state when the primary key signal is input within the initial predetermined time of supplying the operating power to the mobile terminal, and to operate the engineering menu mode when the hidden key is input again. Therefore, it is an object of the present invention to provide an engineering mode operating apparatus and method for a portable terminal that makes it difficult to enter the engineering mode except for the skilled technician.

In order to achieve the above object, the present invention is booted when the operating power is applied by the controller of the mobile terminal, and controls the timer unit in a standby state to count a predetermined time, and a primary key signal is input from the keyboard unit. When the control unit is activated, the engineering unit is activated, and when a hidden key signal is input, the engineering mode is entered to record and modify operating information and parameter values.

In addition, the present invention devised to achieve the above object, the timer unit for counting and outputting a predetermined time set by the control; A control unit which controls the count of the timer unit and checks whether a primary key signal is input within a set time when the operation unit is connected to the timer unit and power supply is supplied; An engineering unit configured to access the control unit and to set and operate an engineering mode to input and manage operation information and parameter information; And a keyboard unit connected to the control unit, inputting operation power supply control, a primary key signal and a hidden key signal, and a dialing signal and a control command.

In addition, the present invention devised in order to achieve the above object, the engineering mode enable state when the primary key signal is input before the predetermined time count is completed when the operating power is supplied by the controller of the portable terminal It is set to enter the engineering mode with the hidden key signal input, and if the primary key signal is not input before completion of the predetermined time of the predetermined time is characterized in a series of processes to block the entry into the engineering mode.

In addition, the present invention devised to achieve the above object, the first step of booting when the operation power supply is confirmed by the controller of the portable terminal and controlling the timer unit to start the counting of a predetermined time; A second process of setting an engineering mode enable state when it is determined by the controller of the process that a primary key signal is input within a timer counting time; When it is confirmed by the control unit of the above process that the hidden key signal is input, it is characterized in that the third step of allowing and operating the engineering mode entry.

It is attached to illustrate the present invention, Figure 2 is a functional configuration of the engineering mode operating device of the mobile terminal according to the present invention, Figure 3 is a flow chart of the engineering mode operating method of the mobile terminal according to the present invention.

Referring to FIG. 2, an engineering mode operating apparatus of a mobile terminal according to the present invention will be described. The wireless unit 100 wirelessly connects to a mobile communication base station under the corresponding control and wirelessly transmits and receives a communication signal.

When connected to the wireless unit 100 and the operating power is supplied, it controls the coefficients of the timer unit 160 and checks whether a primary key signal is input within a set time. When operating power is applied from the power supply unit, the OPERATING program including the application program is loaded from the memory unit 120 and the data DATA is loaded and booted, and the timer unit 160 is controlled. Until the predetermined time count is completed, check whether the primary key signal is applied from the keyboard unit 130, and if the primary key signal is not applied in the confirmation, operate the engineering unit 150. Control the deactivation setting to prevent the setting, and if the PRIMARY KEY signal is applied in the confirmation, the engineering unit 150 is activated and the engineering unit 150 is activated. When the hidden key signal is input in the set state, the controller 110 operates the engineering mode to apply data applied from the keyboard 130 to the engineering unit 150 to record and manage the data. )Wow,

A memory unit 120 connected to the control unit 110 and recording and storing an operation program, an application program, and data DATA under a corresponding control;

A keyboard unit 130 connected to the control unit 110 to input operation power supply control, a primary key signal and a hidden key signal, and input a dialing signal and a control command;

A display unit 140 connected to the control unit 110 and outputting and displaying operation state information and communication data under a corresponding control;

The controller 110 is connected to the control unit 110, and the engineering mode is set and operated to input and manage operation information and parameter information. The operation information which is wirelessly connected to the base station RAN for location registration and is provided with mobile communication service and additional service. And the engineering unit 150 for recording and managing parameter information in the allocated area, and

The timer unit 160 is connected to the control unit 110 and counts and outputs a predetermined time set by the control, and counts the predetermined time and outputs the corresponding information to the control unit 110 when the count is completed. It is a configuration.

Hereinafter, according to the present invention having the configuration described above, the engineering mode operation apparatus of the portable terminal will be described in detail with reference to the accompanying drawings.

The mobile communication terminal MS communicates in a mobile state by wirelessly calling a desired counterpart while moving in a service area formed by a base station RAN, and moving in a range where a service area is formed without being restricted by a place. It is an advanced communication technology.

Accordingly, in order for the mobile terminal MS to receive a normal mobile communication service and an additional service by a mobile communication system including a base station (RAN) and a mobile switching center (MSC), there are a wide variety of operational information and parameters. The mobile terminal (MS) is provided with the operation information and parameters to the system and receives the necessary information, thereby receiving the mobile communication service and the additional service.

As described above, the operation information and the parameter information recorded and stored in the portable terminal are very important information for the use of the mobile communication service and are for the normal operation of the system. Do not change or modify randomly.

Accordingly, the mobile terminal MS is generally equipped with a hidden menu, and an engineering mode is set only when entering the hidden menu. And parameters can be modified or updated.

The portable terminal has a menu for searching for various additional services and selecting and operating the service. The entry of the service menu can be easily performed by selecting and operating a function key button input, but the hidden menu for entering the engineering mode is provided. To enter, you must enter a pass word called a hidden key.

Generally, the secret key for the hidden key is configured by allocating 4 to 8 bits and randomly arranging numbers for dialing, *, #, and the like.

Conventionally, when the hidden key is input at any time while the operating power is supplied to the mobile terminal MS, the engineering mode can be entered.

When the user of the mobile terminal MS, for example, enters a random number while jokingly, enters a hidden key very rarely, and enters an engineering mode. Is inputted by a real number, and the like can be input and set as the operation information or parameter value of the mobile terminal, as described above, the operation information or parameter value by the arbitrary value input by the user's real number, There is a problem that prevents operation in mobile communication services and supplementary services.

Accordingly, the engineering mode is set by inputting only the hidden key, which is a password for setting the mobile terminal MS to the engineering mode, so that the engineering mode is set, and the corresponding operation information and parameter values are set. It is the technique of the present invention to allow input, modification and management.

Since the control unit 110 of the portable terminal is generally supplied with operating power from a power supply unit not shown in the drawing, the control unit 110 stores an operation program, an application program, and data DATA from the memory unit 120. It reads, loads, and boots, and it enters STANDBY state.

As described above, the operation of the standby state can be confirmed because the display unit 140 displays a general display.

The controller 110 in which the standby state is set as described above monitors each function unit and controls the timer unit 160 to count the predetermined time.

The control unit 110 determines whether a primary key signal is input from the keyboard unit 130 within the time counted by the timer unit 160.

Since the primary key signal is a password that is recorded and managed in an allocated area of the memory unit 120, the control unit 110 applies a primary key applied from the keyboard unit 130. KEY) signal is compared with the primary key signal managed by the memory unit 120 to determine whether.

Since the primary key signal input as described above is a password, it is not displayed and displayed on the display unit 140 so as not to be exposed to a third party.

If the control unit 110 determines that the primary key signal applied from the keyboard unit 130 is the same as the primary key signal recorded and managed by the memory unit before the timer unit completes counting the set time, The unit 150 is set to an active state.

Since the activation state of the engineering unit 150 set as described above is maintained until the supply of operating power is cut off, the mobile terminal activates the wireless unit 100 to communicate with a designated party by wireless connection. HIDDEN KEY information may be entered to use for a communication service, an additional service, to maintain a standby state, or to enter an engineering mode.

That is, a first operation power is supplied to the mobile terminal MS, and a primary key signal is input through the keyboard 130 within a predetermined time counted by the timer 160. In this case, before the operation power is cut off to the mobile terminal, a hidden key signal may be input at any time to enter an engineering mode.

In addition, if a primary key signal is not input within a predetermined time counted by the timer unit 160 or an incorrect primary key signal is input after the operating power is first applied to the portable terminal, the controller. Since the engineering unit 150 is set to a blocking state that prevents the operation of the engineering unit 150, no one, including an authorized technician, enters an engineering mode, and records or modifies operation information and parameter values. You cannot manage such things as change or change

Therefore, according to the present invention, the primary key signal is not input within the time set and counted in the timer unit 160 after the operating power is supplied to the mobile terminal MS. If it fails, the engineering mode cannot be entered even when a hidden key signal is input. Therefore, the engineering mode cannot be entered due to a user's mistake, and operation problems and parameter values are not corrected. There is no advantage.
