Abstract: A method of establishing a wireless communication network constituted by moving communication terminals and a wireless communication system are provided. The wireless communication system includes a manager terminal receiving a password from a user, authorizing the received password, and setting a central or local server point, and a plurality of communication terminals receiving the central or local server point from the manager terminal and storing the received central or local server point. Accordingly, it is possible to provide, without establishing a physically fixed relay base station or an access point, the same effect as that of establishing a relay station for a moving communication terminal.

Abstract: A communication method and apparatus using location information of a communication unit are provided. The communication method includes (a) receiving and storing information on other communication terminals within a coverage area, (b) receiving data from a transmission terminal, (c) removing the received data when a communication terminal receiving the data is not a destination of the received data, and (d) when the communication terminal receiving the data is the destination, but not a final destination, transmitting the data to another communication terminal nearest to the final destination within a coverage area of the communication terminal receiving the data. Accordingly, data can be transmitted from one communication terminal to another communication terminal, out of the coverage area of the one communication terminal, using communication terminals as relays, so it is not necessary to establish an extra base station, thereby providing an economical and convenient communication method and apparatus.
