Abstract: A method for sharing an application between a first portable terminal and a second portable terminal includes the first portable terminal collecting application information if an application sharing event occurs, generating a marker including the application information, and displaying the marker; and the second portable terminal capturing an image of the marker including application information, recognizing the marker, extracting the application information from the marker, and installing an application corresponding to the application information from the marker. The first portable terminal includes a marker generating unit to generate the marker including the application information, and a display unit to display the marker. The second portable terminal includes a camera unit to capture an image of the marker, a marker recognizing unit to recognize the marker, a marker analyzing unit to extract the application information from the marker, and an application installing unit to install the application.

Abstract: If a terminal attempts a connection to an Internet site while a server in charge of the site is under maintenance, a connection request may be denied and an error message is sent to the terminal. After the server maintenance returns to a connection enabled state, a connection guide message is sent to notify the terminal. The server includes a communication unit, a message generator, a storage unit to store identification information of the terminal, and a controller. The server generates the error message if the connection attempt occurs while the server is in a connection disabled state, generates the connection guide message if the connection disabled state is released, and transmits the messages to the terminal. The server performing the connection management function may be a content server or a connection management server.

Abstract: A method for transmitting position information of a mobile communication terminal is provided. The method comprises inputting a telephone number of a receiving terminal, selecting to transmit position information, calculating position information of the mobile communication terminal, and transmitting a voice communication with a signal providing position information of the mobile communication terminal. If desired, a user can input a short message service (SMS) text message prior to transmitting or prior to selecting to transmit position information instead of voice communication. Position information of the terminal is derived from the global positioning system (GPS).
