Abstract: PURPOSE: A method for transmitting packet data and a system therefor are provided to efficiently manage a changed IP(Internet Protocol) address of an MS(Mobile Station) and use the changed IP address of the MS. CONSTITUTION: A PDSN(Packet Data Servicing Node) requests an access to an HAAA(Home Authentication, Authorization, and Accounting) about an NAI(Network Access Identifier)(S11). The HAAA transmits an acceptance message as to the request of an NAI user to the PDSN(S12). The PDSN discriminates whether it is accepted as to the NAI transmitted from the HAAA, admits an Internet access of an MS(Mobile Station), and assigns an IP to the MS in an IPCP(IP Control Protocol) stage for setting a PPP(Point-to-Point Protocol) link(S13). The PDSN adds the NAI and a home IP address to a status-client message for notifying the IP address assigned to the MS, and transmits the status-client message to the HAAA(S14). The HAAA transmits an RR(Resource Records) update message about a domain name of the NAI to an MDNS(Mobile Domain Name System) by an RFC 2136 type so that the MDNS updates the IP address of the NAI(S15). The MDNS transmits a response message as to the update of the IP address to an HAAA server(S16). The PDSN transmits a message for starting an accounting to the HAAA(S17). Data are transmitted after a link is set between the MS and the PDSN, the MS repeatedly performs a dormant state and an active state according to the transmission and reception of the data, and accounting information is exchanged between the PDSN and an AAA(S18,S19). If the PPP link is released, the PDSN transmits the status-client message to the HAAA for informing that the IP address assigned to the NAI is released(S21). The HAAA transmits an NAI RR update message to the MDNS for informing that the IP address assigned to the corresponding NAI is released as a null state(S22).

CONSTITUTION: A learner judges whether it is possible to buy desired character virtual goods using a current learner's own faithfulness degree point. If it is possible to buy desired character virtual goods, the learner registers the buying request of corresponding virtual goods(S118). A service server compares the faithfulness degree point of the learner with a price point of the requested virtual goods, and judges whether it is possible to process the buying request. If abnormality does not exists, the service server attaches the corresponding virtual goods to a character of the learner, and reduces the faithfulness degree point of the learner corresponding to the price point of the bought virtual goods(S120). The service server provides a character image to which the virtual goods are attached through a web page(S122). The leaner confirms the character image(S124). The learner confirms whether it is possible to accept actual goods by a color of the virtual goods attached to the character(S126). If it is possible to accept actual goods by the color of the virtual goods, the learner selects corresponding virtual goods on the character image using a mouse, confirms a detailed list of the corresponding goods, and registers the request of acceptance as to the corresponding goods(S128). The service server stores a corresponding request list in an actual goods acceptance request list DB(28g), and removes the corresponding virtual goods from the character of the learner(S130). A manager of the service server confirms the acceptance request list and delivers the corresponding actual goods to the learner(S132), and the learner accepts the delivered actual goods(S134).
