SYSTEM AND METHOD FOR SEARCHING FOR SESSION ID IN WIRELESS MOBILE IP COMMUNICATION SYSTEM
First Claim
1. A method for setting up a session at a Foreign Agent (FA) of a wireless communication system that uses a Mobile Internet Protocol (MIP), the method comprising:
- determining a Network Access Identifier (NAI) of a Mobile Node (MN), when at least one MN requests registration;
assigning a session Identification (ID) to the NAI of the MN;
inserting the session ID assigned to the NAI into an Identification Low field forming a registration request field of a message requesting registration of the MN; and
transmitting the message to a Home Agent (HA) of the MN.

Abstract
A system and a method for performing session setup in a wireless communication system that uses a Mobile Internet Protocol (MIP) are provided. In the method, when at least one Mobile Node (MN) requests registration, a Network Access Identifier (NAI) of the MN is determined. A session Identification (ID) is assigned to the NAI of the MN. The session ID assigned to the NAI is inserted into an Identification Low field forming a registration request field of a message requesting registration of the MN. The message is transmitted to a Home Agent (HA) of the MN. A Foreign Agent (FA) can more easily search for an MN corresponding to a registration replay message provided from the HA, and memory consumption and a time delay that occurs due to a hash method may be reduced.

9. A wireless communication system that uses a Mobile Internet Protocol (MIP), for performing a session setup, the system comprising:
-
a Foreign Agent (FA) for inserting a session Identification (ID) assigned to a Network Access Identifier (NAI) into an Identification Low field forming a registration request field of a message requesting registration of a Mobile Node (MN), when at least one MN requests registration, for assigning a session ID to an NAI of the MN, and for transmitting the message to a Home Agent (HA); and the HA for performing a binding cache for the MN according to registration request information of the MN included in the message provided from the FA, for inserting the session ID of the MN into an Identification Low field forming a registration replay field of a message including registration information of the MN, and for transmitting the message to the FA. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
