       DETAILED DESCRIPTION 
       [0016]    The detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses and/or systems described herein. Various changes, modifications, and equivalents of the systems, apparatuses, and/or methods described herein will likely suggest themselves to those of ordinary skill in the art. Also, descriptions of well-known functions and constructions are omitted to increase clarity and conciseness. Like reference numerals refer to the same or like functions in several aspects throughout the drawings. 
         [0017]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those of ordinary skill in the art to which the present invention pertains can readily implement the present invention. 
       Exemplary Embodiments of Present Invention 
       [0018]    The term “mobile communication terminal” used herein denotes a digital device having wired and wireless communication functions or other functions, that is, a digital device having a memory means and a microprocessor for a computation function, such as a cellular phone, a navigator, a web pad, a personal digital assistant (PDA), a workstation and a personal computer (PC). In a part of this specification, description will be made by taking a mobile communication terminal (e.g., a cellular phone) for example, but the present invention is not limited to a mobile communication terminal. 
         [0019]    The term “inactive state” used herein denotes a state in which a mobile communication terminal is capable of communication, but a display screen is off. Even when the display screen is off, a predetermined function (e.g., a music play function) may be carried out. Thus, the term “inactive state” used herein corresponds to a comprehensive concept of a state in which the display screen is off regardless of whether or not the mobile communication is performing a predetermined operation. However, a state in which the mobile communication terminal is completely turned off is excluded. 
         [0020]    The term “active state” used herein denotes a state in which a display screen of a mobile communication terminal is on. A switch from the “inactive state” to the “active state” means switching from a state in which the display screen is off to a state in which the display screen is on regardless of information displayed on the display screen that is on. For example, even a case in which only a lock image is displayed may be referred to as the “active state” of the mobile communication terminal. 
         [0021]    Constitution of Overall System 
         [0022]      FIG. 1  schematically shows an overall constitution of a system for displaying an advertisement upon activation of a mobile communication terminal according to the present invention. 
         [0023]    Referring to  FIG. 1 , an overall system according to an exemplary embodiment of the present invention may include a mobile communication terminal  100 , an advertisement providing system  200 , an advertiser server  300 , and another service providing server  400 . 
         [0024]    According to an exemplary embodiment, the mobile communication terminal  100 , the advertisement providing system  200 , the advertiser server  300 , and the other service providing server  400  may communicate via a communication network. The communication network may be configured for any form of communication such as wired communication and wireless communication, and implemented as a variety of communication networks such as a local area network (LAN), a metropolitan area network (MAN) and a wide area network (WAN). Preferably, the communication network according to an exemplary embodiment of the present invention is the known world wide web (WWW), or the like. 
         [0025]    According to an exemplary embodiment, the mobile communication terminal  100  may include a display unit  110  and an activation button  120 . 
         [0026]    In an example of  FIG. 1 , the display unit  110  is provided in a front side of a frame constituting the mobile communication terminal  100 , and the activation button  120  is provided under the display unit  110 . However, the display unit  110  and the activation button  120  may be formed in a different way than as mentioned above. For example, the display unit  100  may not be formed in an overall side of the mobile communication terminal  100 . In other words, the display unit  100  may be formed in at least a portion of the display unit  100 , and the activation button  120  may be formed in a different portion than the display unit. 
         [0027]    The display unit  110  displays various information on operation states of the mobile communication terminal  100 , and also displays an interface for an input of a user when the mobile communication terminal  100  is driven by a touch screen. In general, when the user has not manipulated the mobile communication terminal  100  for a predetermined time, the mobile communication terminal  100  is placed in the inactive state. Manipulation by the user denotes input through the interface displayed on the display unit  110 , manipulation through the button  120 , manipulation through another function key (e.g., a volume key), or so on. A condition for the inactive state may be set by the user. For example, a setting menu can be accessed through the interface displayed on the display unit  110  to set the condition. By way of example, when there has been no user input for the predetermined time, the mobile communication terminal  100  may be switched to the inactive state. Meanwhile, when another button (e.g., on/off button) provided in the mobile communication terminal  100  is pressed, the mobile communication terminal  100  may be switched to the inactive state. For example, when the on/off button is pressed for a long time while the mobile communication terminal  100  is in the active state, the mobile communication terminal  100  may be turned off, but when the on/off button is pressed for a short time, the mobile communication terminal  100  may be placed in the inactive state, which is a communication-enabled state in which a phone call can be received. 
         [0028]    The activation button  120  is a means for switching the mobile communication terminal  100  from the inactive state to the active state. In other words, when the user presses the activation button  120  while the mobile communication terminal  100  is in the inactive state, the mobile communication terminal  100  is switched to the active state.  FIG. 1  shows a state in which a lock image is displayed on the display unit  110  when the activation button  120  is pressed while the mobile communication terminal  100  is in the inactive state. However, the activation button  120  may function as a means for another operation (e.g., a means for displaying a standby image while an operation state is displayed on the display unit  110 , or a means for displaying a list of currently running programs). 
         [0029]    In an exemplary embodiment of the present invention, when the user presses the activation button  120  while the mobile communication terminal  100  is in the inactive state, the mobile communication terminal  100  is switched to the active state, and also a predetermined advertisement is displayed on the display unit  110 .  FIG. 2  shows an example in which an advertisement is displayed on the display unit  110  according to an exemplary embodiment of the present invention when the mobile communication terminal  100  is switched to the active state. 
         [0030]    In an exemplary embodiment, display of an advertisement may be performed as an application previously installed in the mobile communication terminal  100  is run. In other words, upon activation of the mobile communication terminal  100  by the activation button  120 , the application enabling display of an advertisement may be run, and thus the advertisement may be displayed on the display unit  110 . The application may have been previously transmitted from an external system, such as the advertisement providing system  200  or the advertiser server  300 , and installed. 
         [0031]    Meanwhile, in another exemplary embodiment, when the mobile communication terminal  100  is activated, an advertisement provided by the advertisement providing system  200  may be displayed on the display unit  110 . Advertising information from the advertisement providing system  200  may be received before the mobile communication terminal  100  is activated (e.g., when the mobile communication terminal  100  is deactivated, or at other times), or upon activation of the mobile communication terminal  100 . 
         [0032]    Advertisements may be randomly selected and displayed, or only advertisements selected under a predetermined condition may be displayed. 
         [0033]    In an exemplary embodiment, on the basis of current location information on the mobile communication terminal  100 , only advertisements related to the current location may be displayed. Specifically, on the basis of current location information on the mobile communication terminal  100 , advertisements for companies around the location may be displayed. A location of the mobile communication terminal  100  may be detected upon activation, or constantly detected in real time. 
         [0034]    In another exemplary embodiment, on the basis of information on the user of the mobile communication terminal  100 , customized advertisements may be displayed. For example, on the basis of the gender, age, residence, job, interests, etc. of the user, advertisements for related companies may be displayed. The user information may be input and stored by the user when the user subscribes to an advertisement providing service or installs an application enabling display of advertisements. The user information may be stored in the mobile communication terminal  100 , or transmitted to and stored in the advertisement providing system  200 . 
         [0035]    Meanwhile, in still another exemplary embodiment of the present invention, different advertisements may be displayed on the display unit  110  according to time. For example, advertisements for restaurants may be displayed at mealtimes, and advertisements for dramas broadcast at the corresponding time may be displayed at the drama broadcasting time. 
         [0036]    Factors whereby the type of a displayed advertisement is determined have been described above, and at least two of these factors may be combined to determine the type of an advertisement. For example, an advertisement may be displayed in consideration of both current location information and user information. Also, advertisements may come in various forms such as brand advertisements, program advertisements, service advertisements, promotion advertisements and event advertisements, in addition to advertisements of specific products. 
         [0037]    Meanwhile, in an exemplary embodiment of the present invention, when the user makes an additional input while an advertisement is displayed on the display unit  110 , various operations may be performed. As an example, when the user clicks the displayed advertisement, access to a web page related to the advertisement, etc. may be performed. The web page may provide information on a company or product related to the advertisement, discount information, location information, and so on. 
         [0038]    As another example, when the corresponding advertisement is clicked, a predetermined portion of the advertising revenue earned by an advertising company may be used as a donation.  FIG. 3  illustrates a process of making a donation by clicking an advertisement displayed on the display unit  110 . Referring to  FIG. 3 , an interface for selecting whether or not to “Make Donation” may be provided by clicking an advertisement. When the user requests “Make Donation,” a portion of the advertising revenue may be used as a donation, and the related image (e.g., a social network page such as Angel Book) may be displayed. 
         [0039]    Meanwhile, in an exemplary embodiment of the present invention, a specific application may be run when the mobile communication terminal  100  is activated, but an advertisement may be displayed only when there is no update of information to be provided to the user by the application. For example, when the mobile communication terminal  100  is activated, a social network service provided by the other service providing server  400  may be run, and the corresponding page may be displayed on the display unit  110 . At this time, an advertisement may be displayed only when there is no new content that has not been checked by the user on the page. 
         [0040]    An overall system for displaying an advertisement upon activation of a mobile communication terminal according to an exemplary embodiment of the present invention will be described below. 
         [0041]    Advertisement Providing System 
         [0042]      FIG. 4  is a block diagram showing a constitution of an advertisement providing system according to an exemplary embodiment of the present invention. 
         [0043]    Referring to  FIG. 4 , an advertisement providing system  200  may include an application provider  210 , an activation sensor  220 , an advertisement provider  230 , an additional function provider  240 , a database  250 , a communicator  260 , and a controller  270 . In an exemplary embodiment of the present invention, the application provider  210 , the activation sensor  220 , the advertisement provider  230 , the additional function provider  240 , the database  250 , the communicator  260  and the controller  270  may be program modules or pieces of hardware capable of communicating with an external apparatus. These program modules or pieces of hardware may be included in the advertisement providing system  200  or another apparatus capable of communicating with the advertisement providing system  200  in the form of an operating system (OS), application program modules and other program modules, and may be physically stored in various known memories. These program modules or pieces of hardware include routines, subroutines, programs, objects, components, data structures, etc. for performing a specific task to be described later or executing a specific abstract data type, but are not limited to these. 
         [0044]    The application provider  210  provides an application for displaying an advertisement on the display unit  110  when the mobile communication terminal  100  is switched to the active state. A user may access the advertisement providing system  200  through the mobile communication terminal  100  to receive and install the application. The application may have a function of transmitting information on the current location of the mobile communication terminal  100 , user information, time information at the current location, etc. to the advertisement providing system  200 . However, when a method of displaying an advertisement on the display unit  110  when the mobile communication terminal  100  is switched to the active state is used without installation of the application, the application provider  210  may be omitted. 
         [0045]    The activation sensor  220  according to an exemplary embodiment may sense that the mobile communication terminal  100  is switched from the inactive state to the active state. When the user presses the activation button  120  of the mobile communication terminal, the mobile communication terminal  100  may transmit a signal indicating activation of the mobile communication terminal  100  to the advertisement providing system  200 . 
         [0046]    When it is sensed that the mobile communication terminal  100  is activated, the advertisement provider  230  according to an exemplary embodiment functions to display a predetermined advertisement on the display unit  110  of the mobile communication terminal  100 . The advertisement may have been previously stored in the mobile communication terminal  100  or the database  250  of the advertisement providing system  200 . The advertisement providing system  200  may receive advertising content from the advertiser server  300  in advance and store the advertising content in the database  250 . The advertising content may be categorized and stored according to predetermined classification criteria. For example, according to locations, user characteristics and time, advertising content to be provided may be classified and stored. The advertisement provider  230  may select a piece of advertising content to be provided when the mobile communication terminal  100  is activated, with reference to the database  250 , under a predetermined condition and provide the selected piece of advertising content to the mobile communication terminal  100 . Meanwhile, an application provided from the other service providing server  400  may be set to run when the mobile communication terminal  100  is switched to the active state. In this case, when there is no new information to be provided with the application to the user, or to be provided to the user by the application, an advertisement may be provided. 
         [0047]    On the other hand, in another exemplary embodiment of the present invention, pieces of advertising content, condition information on advertisements to be displayed, etc. all may be included in the application provided by the application provider  210 , and the mobile communication terminal  100  may perform an advertisement display operation by itself when it is switched to the active state. 
         [0048]    The additional function provider  240  according to an exemplary embodiment performs an additional function according to a request of the user, on the basis of an advertisement provided by the advertisement provider  230 . For example, the additional function provider  240  may provide a function of displaying additional information on the advertisement in response to the user&#39;s click on the advertisement, a function of accessing the related web page, a function of providing information on the advertised product or service, a function of using a portion of the advertising revenue as a donation, and other functions. 
         [0049]    In a modified embodiment of the present invention, the above-mentioned functions of the advertisement providing system  200  may be independently performed in the mobile communication terminal  100 . In other words, in the mobile communication terminal  100 , activation may be sensed, and display of an advertisement, performance of an additional function through a click of the advertisement, etc. may be achieved. 
         [0050]    The communicator  260  according to an exemplary embodiment of the present invention enables communication between the advertisement providing system  200  and the mobile communication terminal  100 , the advertiser server  300 , the other service providing server  400 , and so on. 
         [0051]    In an exemplary embodiment, the controller  270  may perform a function of controlling data flow between the application provider  210 , the activation sensor  220 , the advertisement provider  230 , the additional function provider  240 , the database  250  and the communicator  260 . In other words, the controller  270  according to the present invention may control the application provider  210 , the activation sensor  220 , the advertisement provider  230 , the additional function provider  240 , the database  250  and the communicator  260  to respectively perform their unique functions. 
         [0052]    The above-described exemplary embodiments of the present invention can be implemented in the form of program commands executable by means of various computer components and recorded in a computer-readable recording medium. The computer-readable recording medium can store any or a combination of programs, commands, data files, data structures, and so on. The program commands recorded in the computer-readable recording medium may be specially designed and structured for the present invention, or program commands well-known and usable by those of ordinary skill in the art. Examples of the computer-readable recording medium include magnetic media such as a hard disk, a floppy disk and a magnetic tape, optical media such as compact disc read-only memory (CD-ROM) and digital versatile disc (DVD), magneto-optical media such as a floptical disk, and hardware devices that are specially structured to store and execute program commands such as a ROM, a random access memory (RAM) and a flash memory. The program commands include high-level language codes that can be executed by a computer using an interpreter, as well as machine language code produced by a compiler. The hardware devices can be configured to operate as one or more software modules to perform a process of the present invention and vice versa. 
         [0053]    In exemplary embodiments of the present invention, an advertisement display function is added to an activation button that a terminal generally has, such that advertising revenue can be created from advertisement display on the terminal and efficient advertisement effects can be obtained when the activation button is habitually pressed by a user. 
         [0054]    It will be apparent to those of ordinary skill in the art that various modifications can be made to the exemplary embodiments of the invention described above. However, as long as modifications fall within the scope of the appended claims and their equivalents, they should not be misconstrued as a departure from the scope of the invention itself.
