Abstract
Provided are a communication terminal operable as a server and a method for processing a request therein. The communication terminal comprises a user input unit, a storage unit, a communication unit, and a control unit. The user input unit receives a user input. The storage unit stores software storing software necessary to process a request from a client terminal. The communication unit receives the request from the client terminal connected to a relay server, and sends data through the relay server in response to the request. The control unit receives the request from the client terminal, processes the request, and controls the communication unit according to the user input or the software stored in the storage unit. Here, the communication terminal is connected to the client server via a gateway server converting a private IP address into a certified IP address and the relay server having a common IP address and forwarding data.
