METHOD FOR IP COMMUNICATION USING CELLULAR TELEPHONE NUMBER OF MOBILE COMMUNICATION TERMINAL AND SERVER HAVING FUNCTION THEREOF

摘要

PURPOSE: An IP communication method and a server of the same are provided to implement IP based message communication without complicated information exchange and communication connection with various communication equipment by mobile telecommunication operators. CONSTITUTION: A first mobile communication terminal performs a CTN(Cellular Telephone Number) query by CTN input of a second mobile communication terminal(S10). A mobile communication server confirms a public IP mapped to the CTN of the second mobile communication terminal through a mapping table of a database(S12). The mobile communication server transmits the public IP to the first mobile communication terminal(S18). The first and the second mobile communication terminals performs message communication using the public IP(S20).
