CROSS-REFERENCE TO RELATED APPLICATION AND CLAIM OF PRIORITY 
       [0001]    The present application is related to and claims priority under 35 U.S.C. §119(a) to a Korean Patent Application filed in the Korean Intellectual Property Office on Feb. 1, 2011 and assigned Serial No. 10-2011-0010030, the contents of which are herein incorporated by reference. 
       TECHNICAL FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to computer networks, and more particularly, to a system and method for executing a cloud computing task. 
       BACKGROUND OF THE INVENTION 
       [0003]    Portable terminals such as portable mobile terminals (e.g., cellular phones), electronic notebooks, personal multi-terminals, and the like have become popular due to the growth of telecommunication technology. These portable terminals have become an often used technique for rapidly exchanging information with others. Now, the Internet often provides various services to the portable terminals. 
         [0004]    Cloud computing has become more popular in recent years. Cloud computing is based on a concept that all information of a user may be stored in a server on the Internet in a manner that it may be used when ever and where ever the user has access to the Internet. In other words, cloud computing generally refers to a computer service that uses computer resources such as software existing in an intangible form to integrate computer resources that are scattered at different physical locations using virtual technology. Cloud computing is performed using a relatively complex combination of utility computing, Software As a service (SAAS) and Grid computing concepts. Namely, from the viewpoint of a user, cloud computing may be similar to utility computing or SAAS in that fees are assessed in proportion to the use of hardware and/or software computing resources. From the viewpoint of the resource provider, cloud computing is generally similar to the concept of grid computing in that it can allow dispersed computing resources to be used with one another for being utilized as a single computing resource. 
         [0000]    If such cloud computing is utilized, the performance of computers may be enhanced by sparing the limited resources of computer (for example; processing capacity of a CPU and a memory, a storage space of hard-disk and the like) due to the fact that computers connected on a network can share information in a synergistic manner. Many computers may have physical limits even though high efficient CPU are used. Additionally, computers functioning together may aid in solving such problem a plural of CPU can be connected in parallel for distributed processing. Namely, if many computing devices such as PCs, servers, PDAs, and the like are connected with a single network to function as a dispersed resource, the capacity of information processed may be improved considerably in some cases. If such a concept were to apply to the Internet, it may, in some cases, be possible to transfer data to a plural of unspecified devices on the Internet and collect data in a server after processing.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]      FIGS. 1 through 3 , discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged computing devices. Exemplary embodiments of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Also, the terms used herein are defined according to the functions of the present invention. Thus, the terms may vary depending on user&#39;s or operator&#39;s intention and usage. That is, the terms used herein must be understood based on the descriptions made herein. 
         [0018]    One purpose of the present invention may be to provide a system and method in which a client terminal is made to participate in cloud computing when it is operated by a battery that is being recharged, or there is no additional communication fee assessed for the cloud computing service. 
         [0019]      FIG. 1  illustrates an example cloud computing structure according to an embodiment of the present invention. For example, if cloud computing is utilized, an executable task relating to a corresponding project can be shared among multiple client terminals for processing by coupling various personal computers (PCs), mobile phones, and the like via a network. The PCs and mobile phones made to participate in cloud computing may become client terminals in communication with a corresponding server. In particular, a user can access a homepage built in the corresponding server and participate in a corresponding project voluntarily through cloud computing. 
         [0020]    The user can designate a time for executing cloud computing with his client terminal. For instance, he can set up his terminal to execute cloud computing during his bedtime. Also, he can set up his terminal to execute a cloud computing task during a sleep mode of his terminal. 
         [0021]    In one embodiment, the client user can set his terminal to not execute a cloud computing task if his client terminal is not recharging. Contrary to PCs, mobile phones often operate with a rechargeable battery. If a battery for operating a terminal is discharged or mostly discharged, cloud computing may be forcibly terminated such that a corresponding task executed on the computing cloud cannot be processed effectively. 
         [0022]    In another embodiment, the user can set up his terminal to execute a cloud computing task when he can communicate without fee. For example, only when his mobile phone is within a WiFi (wireless fidelity) zone and he can communicate without fee, his terminal accesses the server that provides cloud computing. In some cases, the Internet can be used at no cost when certain mobile phones are located within WiFi hotspots. However, if cloud computing is executed at locations where free interne access is not allowed, it&#39;s use for cloud computing may burden the user with additional fee. 
         [0023]    The server may distribute an executable interface program to members that helps to set up various parameters related to the operation of the cloud computing environment. The user may access the server with his terminal and agree to execute cloud computing for a corresponding project that is provided with the interface program. Then, the client user can set up other parameters for executing cloud computing environment under the conditions that the interface program may provide. For instance, the user can set up his client terminal to access the server for downloading data only one a.m. to five a.m. and to transfer the result to the server after the data is analyzed. Also, the user can set up his client terminal to not access the corresponding server if the client terminal is not recharging nor in a WiFi zone. 
         [0024]      FIG. 2  illustrates an example structure of a client terminal according to an embodiment of the present invention. 
         [0025]    Referring to  FIG. 2 , a client terminal according to the present invention comprises memory  21  to store the indicated object date, a display  22  to display information associated with stored data, an input device  23  for receiving input from a user, a communication interface  24  for communicating and a controller  25  to control the overall operation of the terminal. The input device  23  receives input from the user when the system receives conditions associated with execution of the cloud computing environment with his client terminal. The memory  21  stores the user interface program that sets up the conditions for executing cloud computing with the terminal according to an example of the present invention and the resulting information. The controller  25  executes cloud computing according to an embodiment of the present invention, as described in detail below. 
         [0026]      FIG. 3  illustrates an example process for executing cloud computing with a client terminal according to the present invention. 
         [0027]    Referring to  FIG. 3 , the controller  25  checks  303  whether it is possible to access to the Internet for free (e.g., WiFi) or not, if a predetermined time is reached  301 . If it is possible to utilize the Internet for free, the controller  25  checks whether the terminal is recharging or not  305 . If recharging, the controller  25  accesses a corresponding server through the Internet, receives data to analyze, and then transfer the result to the server  307 . If it is possible neither to utilize the Internet for free nor the terminal being in a recharging state, the controller  25  executes step  303  and the following steps until a critical time is reached  309 . 
         [0028]    In certain embodiments, a user may access the server for executing a task with his client terminal according to an example of the present invention for the executing a cloud computing project when three conditions are met, namely during a predetermined time period, access to the Internet for free, and the terminal is recharging. In other embodiments, the present invention is not limited to the above mentioned conditions, such as when only one or two conditions among the three conditions is met. 
         [0029]    And also, according to the example described above, the conditions are assessed according to conditions specified by the client terminal. In other embodiments, the server can request cloud computing to be performed on the client terminal at predetermined time periods in which the client terminal requested for cloud computing informs the server if it is possible to free access to the Internet, or if the client terminal is recharging. In this particular embodiment, the server judges the object of the cloud computing of the client terminal on the basis of information provided by the client terminal. For example, the time periods during which the server requests cloud computing be executed on the client terminal can be set up on the user interface that is provided in a homepage or website provided by the server. 
         [0030]    In conclusion, according to the system and method of the present invention, a client terminal that executes cloud computing efficiently can be selected for executing a task of a cloud computing environment that may result in improved work efficiency in certain embodiments. 
         [0031]    While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
