Method for assigning IP address to mobile node in code division multiple access system
First Claim
1. A method for assigning an Internet protocol address to a mobile node in a mobile communication system, comprising the steps of:
- storing, by a database, identification information of said mobile node and grades of mobile nodes indicating a grade of qualification for assignment of the Internet protocol address;
when an Internet protocol address assignment request associated with an arbitrary mobile node is received, identifying a grade of said mobile node from said database;
selecting an Internet protocol address pool from Internet protocol address pools of various grades on the basis of the grade of said mobile node, the Internet protocol address pools containing assignable Internet protocol addresses; and
selecting an available Internet protocol address from the Internet protocol address pool and assigning the selected Internet protocol address to said mobile node.

Abstract
A method for assigning an IP (Internet Protocol) address to an MN (Mobile Node) in a CDMA (Code Division Multiple Access) system, and more particularly to a method for assigning an IP address on the basis of a grade of an MN. In a method for assigning an IP address on the basis of a grade of an MN in a CDMA data communication system, the system including a database storing information of grades of MNs, a grade of the MN is identified from the database when an IP address assignment request associated with an arbitrary MN is received. Then, an IP address pool is selected from IP address pools of various grades on the basis of the grade of the MN, the IP address pools containing assignable IP addresses. Then, an IP address is selected from the IP address pool and the selected IP address is assigned to the MN.
