PURPOSE: A method for identify and processing a dynamic IP and a static IP when an ISP mobile subscriber accesses the third generation GPRS(General Packet Radio Service) network is provided to additionally define a flag field for an ISP mobile subscriber's IP in a PPP(Point to Point Protocol) IPCP(Internet Packet Control Protocol) packet in order to indicate whether the IP is dynamic or static and to add an ISP identifier field in order to easily recognize ISP mobile subscriber processing. CONSTITUTION: In an initialization state, a TE(Terminal Equipment) inputs a user ID and a user password, or a secrete key, and attempts packet mobile network access and registration(510,511). After executing LCP/CHAP/IPCP negotiation with an MT(Mobile Terminal)(512), the TE creates a PDP context message on the basis of an end user information element(513), outputs the created PDP context to the network to request the start of a session(514). As a GGSN(Gateway GPRS Support Node) attempts ISP network access(515), an ISP network mobile subscriber's IP is allocated to the GGSN. The GGSN transmits a PDP session response message, including the allocated IP, to the TE through the MT(516). The TE starts packet mobile communication service and Internet service using the allocated IP(517).
