Abstract
Provided is a method for allocating an Internet protocol (IP) address to a mobile station in a mobile communication system. The method includes the steps of: a) receiving an 'Activate Packet Data Protocol (PDP) request' message including router solicitation from the mobile station; b) acquiring a global IP address of the mobile station by performing the router solicitation and a router advertisement procedure instead of the mobile station; and c) loading the acquired global IP address in an 'Activate PDP context Accept' message and transferring the “Activate PDP context Accept” message to the mobile station.
