The present invention relates to a mobile communication terminal having a work state storage / playback function and a work state storage / playback method. More specifically, during the execution of a specific task of the mobile terminal, the user of the mobile terminal arbitrarily stores the work state of the mobile terminal that is currently being executed by using the work state storage menu, and then uses the work state playback menu to arbitrate previous work. The present invention relates to a mobile communication terminal having a work state storage / playback function capable of returning to a state and continuing a work, and a work state storage / playback method.

Today, mobile terminals can make phone calls anytime, anywhere. Due to the simplicity and convenience of carrying, many people use it as a necessity of life. Furthermore, the mobile communication terminal has a short message service (SMS), a phone book registration, a schedule management, an electronic notebook function, etc., and has been transformed into a means for managing personal information beyond simply a phone call. .

Recently, it is a complex personal portable device that can solve many functions for various conveniences of modern social life, from calculators, games, stopwatch functions to cameras, camcorders, TV viewing, Internet and payment methods. Its functions are diversified, complicated and advanced.

As the mobile communication terminal, which provided only a simple phone call function, is increasingly diversified and complicated, various function menus are required in the mobile terminal to execute various functions of the mobile communication terminal. As a procedure for selecting and designating the function menus to execute a desired function, key manipulation of the mobile communication terminal also has to be complicated and inconvenient.

Therefore, a shortcut key has been developed to enhance the user's convenience according to the key operation. The shortcut key means a key for executing a corresponding function at a time as a single key. These shortcut keys can be broadly classified into two types, one of which has a built-in shortcut key for vibrating mode, lock mode, access to additional services, etc. for a specific key predetermined in the mobile communication terminal itself. The terminal user arbitrarily sets a specific menu as a shortcut function for his convenience.

The former was a form of a shortcut key provided by an early mobile communication terminal, and its function was limited. For example, the '*' key of the mobile communication terminal is set as a shortcut key for the vibration mode, and the '#' key is set as a shortcut key for the lock mode so that a corresponding function is immediately performed when the mobile terminal user presses the shortcut key. Is used as a shortcut, the mobile phone can be dialed back to the previous phone number, or a separate key can be designed in hardware to go directly to the wireless internet connection or camera shooting menu. Shortcuts for performing a specific function are fixedly designed at the time of manufacturing the terminal, so that a user cannot arbitrarily designate a shortcut key for performing more functions.

On the other hand, unlike the former, the mobile communication terminal user can directly designate a shortcut key so that the user can go directly to a menu of a desired function. The mobile communication terminal provides the service contents provided in order to provide various services in a hierarchical menu list so that the user of the mobile terminal can select a necessary service from the menu list. It uses the hierarchical path that executes step by step repeatedly from the highest level menu to the next level sub menu, then back to the next level sub menu to reach the desired function menu. It is a form of a user-specified shortcut key that allows a mobile communication terminal user to arbitrarily designate a shortcut key for performing a specific function to reach the designated specific function menu directly from the highest menu. In other words, it is a shortcut type that enhances user convenience so that a user of a mobile communication terminal can use a shortcut key provided by a mobile communication terminal, and actively enable a user to designate and use a shortcut key as desired.

1 is a flowchart illustrating an execution method through a user-specified shortcut key path among menu selection paths in the related art. The user of the mobile communication terminal first selects a shortcut key setting menu among menus of the mobile communication terminal (S100), specifies a shortcut key to perform a specific function (S102), and assigns and saves a specific function to the designated shortcut key (S104). Thereafter, if the user directly executes the shortcut key without having to go through the hierarchical path (S106), the specific function set in the designated shortcut key is executed (S108).

As described above, the shortcut key function of the conventional mobile communication terminal has a form of using a shortcut key built in the mobile communication terminal itself or using a user-specified shortcut key that is more suitable for user convenience. Assigned Shortcut Keys You can also use the number key of the mobile terminal as a shortcut to make a call to the number stored at the address when the user presses the number key, or to go to the initial screen of a menu only to execute a specific function. It was found that only a limited number of users have access to a function that users can arbitrarily specify by using shortcut keys.

For example, if the user of the mobile communication terminal designates a shortcut key to use the calculator function, executing the calculator function using the shortcut key only shows the initial screen when using the calculator for the first time, but does not display the previously used calculation screen. . In addition, if you specify a menu (album menu) for viewing saved pictures on the camera phone as a shortcut key, the shortcut menu only shows the initial album menu screen. In addition, if the phone book menu is specified as a shortcut key, the shortcut will only display the initial screen of the phone book menu, but the screen for the phone number or address for a specific person previously viewed will not appear immediately. You must run

As described above, the conventional custom shortcut key has a function of shortening only the upper menu to reach a menu of a specific function and moving directly to the initial screen of the designated function menu, and furthermore, to a state of a function previously executed by a user. There was an inconvenience that could not provide a shortcut function to move again. For example, to use the calculator on a mobile terminal to make a phone call or move to another function menu, you must exit the calculator you are using. Even if you use the shortcut key to go directly to the calculator menu, only the initial screen of the calculator menu appears. Previously used calculation screens can no longer be used over and over again, and the calculations must be repeated. Similarly, when searching for address book, searching photos, listening to music, and accessing the wireless Internet, even if you use other functions and then use shortcut keys to return to the function menu, only the initial screen of a specific function menu is displayed. There is an inconvenience that you cannot do it again.

As a way to solve this inconvenience, you can think of how to save the work currently being performed by the mobile terminal and restore it as it is. Until now, the call list is automatically saved and the call is made to a specific phone number. If you make a message using SMS, or if you make a call while using a SMS or use other functions of the mobile terminal, the mobile terminal automatically saves the message you are working on and then returns to the message creation screen. There is only a way to make it. However, such a method also records only the latest received or sent data, and the temporarily stored data is deleted from the memory one by one after the old data when the set number is exceeded. The list will be erased, and even if you want to save the phone number of the specific call list in the phone book, you will have to go through several steps. Even if the message you were working on is automatically saved and restored, the most recently written message will be deleted. Only the work screen is restored, but the previously written message is not restored, which causes inconvenience.

That is, the conventional mobile communication terminal has only a shortcut function for entering only the initial screen of the function menu for executing a specific function even by a user specified shortcut key, and the restoration form is very limited by the method of saving and restoring the previous work. It is only a passive method by the mobile communication terminal, there is a problem that the user of the mobile communication terminal can not easily reach the desired working state arbitrarily.

In order to solve this problem, the present invention, the mobile communication terminal user of the current state of the mobile terminal is randomly stored using the work state storage menu, and then randomly selected by the mobile communication terminal previously worked using the work state playback menu It is an object of the present invention to provide a mobile communication terminal and a method thereof capable of continuing a previously stored work by restoring a work state and a screen of a function.
