Title: Method and Device for Data Packet Communication using Specific Name of Mobile Communication Terminal
Inventor: KIM GYEONG HUI
IPC: H04L12/66
Filed: 2001-11-19
Abstract: PURPOSE: A method for performing data packet communication of a mobile communication terminal by using an inherent name of the terminal and a mobile communication terminal using the same are provided to enable a user to request packet communication by using a name or a telephone number of the other party's terminal, without confirming and re-inputting dynamic IP addresses differently given to the other party's terminal. CONSTITUTION: A controller inputs an inherent name or a telephone number of the other party for data packet communication, receives a self dynamic IP address assigned by an IWF(Inter Working Function)/PDSN(Packet Data Service Node), and obtains a dynamic IP address of the other party stored in the inherent name or the telephone number, then forms a data packet transmission channel with the other party's terminal. An external DNS(Domain Name System) interworks with the IWF/PDSN, a BSC, or an MSC, and manages states of mobile communication terminals. When a specific terminal gives a packet call service, the DNS system sets a dynamic IP address in the corresponding terminal. If the terminal is not in a packet call connection state, the DNS sets an IP address field to '0' or 'null'.
