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.

Claims

1. A wireless communication method comprising the steps of:

(a) each communication terminal within a coverage area receiving and storing information on other communication terminals within the coverage area;

(b) one communication terminal among the communication terminals within the coverage area receiving and storing data from another communication terminal among the communication terminals within the coverage area;

(c) the communication terminal receiving the data analyzing the received data to determine whether the communication terminal is a destination of the received data and a final destination of the received data; and

(d) when the communication terminal is determined as the destination but not the final destination, the communication terminal transmitting the data to another communication terminal nearest to a communication terminal, which corresponds to the final destination, within a coverage area of the communication terminal that has received the data.

2. A computer readable recording medium on which a program for executing the wireless communication method of claim 1 in a computer is recorded.

3. The wireless communication method of claim 1, wherein in step (d), the communication terminal receiving the data searches communication terminals within its coverage area for the communication terminal corresponding to the final destination and when the communication terminal corresponding to the final destination is found, transmits the data to the communication terminal corresponding to the final destination.

4. A computer readable recording medium on which a program for executing the wireless communication method of claim 3 in a computer is recorded.

5. The wireless communication method of claim 3, wherein in step (a), the information on the communication terminals within the coverage area comprises latitude and longitude information indicating a position of each communication terminal, in step (b), the received data comprises latitude and longitude information indicating a position of the communication terminal receiving the data and latitude and longitude information indicating a position of the communication terminal corresponding to the final destination, and

the communication terminal nearest to the communication terminal corresponding to the final destination is selected based on latitude and longitude information of the communication terminals within the coverage area and the latitude and longitude information indicating the position of the communication terminal corresponding to the final destination.

6. A computer readable recording medium on which a program for executing the wireless communication method of claim in a computer is recorded.

7. A wireless communication apparatus, comprising:

a communication unit receiving data from external communication devices and transmitting data to the external communication devices;

a coordinate management unit storing position information of the wireless communication apparatus and the external communication devices within a coverage area of the wireless communication apparatus;

a data analyzing unit analyzing reception data to determine whether the wireless communication apparatus is a destination of the reception data and is a final destination of the reception data; and

a relay unit transmitting the reception data to the final destination or another communication device nearest to the final destination among the communication devices within the coverage area when the data analyzing unit determines that the wireless communication apparatus is not the final destination.

8. A wireless communication apparatus comprising:

a communication unit receiving data from external communication devices and transmitting data to the external communication devices;

a first storing unit storing system information which includes function information and position information of the wireless communication apparatus;

a second storing unit storing position information of the external communication devices within a coverage area of the wireless communication apparatus;

a coordinate management unit storing position information of the wireless communication apparatus and the external communication devices within a coverage area of the wireless communication apparatus;

a data analyzing unit analyzing reception data to determine whether the wireless communication apparatus is a destination of the reception data and is a final destination of the reception data; and

a relay unit transmitting the reception data to the final destination or another communication device nearest to the final destination among the communication devices within the coverage area when the data analyzing unit determines that the wireless communication apparatus is not the final destination,

wherein the wireless communication apparatus acts as one among a first server which contains position information of each communication device and endows function of each communication device, a second server which collects information of other communication devices within a coverage area of the second server, and a communication terminal which transmits its unique code and position information, according to the function defined by the function information.

9. A communication packet structure comprising:

a destination sort code portion indicating a sort of destination as a single terminal or a group of terminals;

a destination position portion containing a unique code, latitude, and longitude of a destination terminal;

a final destination position portion containing a unique code, latitude, and longitude of a final destination terminal; and

a data portion containing information to be transmitted to the final destination terminal.
