Abstract:
A method for managing internet protocol handoff in a network system is provided to solve a problem about HOL(Head Of Line) that the transmission of a signal packet for handoff is delayed by data packet by physically dividing the data packet and signal packet when handoff of a moving nod is occurred to an external network. A method for managing internet protocol handoff in a network system comprises the following steps of: receiving registration request message through moving agent moved from a moving nod when the moving nod is moved to an arbitrary moving agent(501); transmitting the received registration request message to the previously located moving agent by the moving nod without modification(505); transmitting the registration response message in response to the registration message to the moved moving agent without modification(508); and processing IP(Internet Protocol) handoff by classifying a signal packet path from a data packet path.
Abstract:
An IP(Internet Protocol) handoff supply method for an MN(Mobile Node) in a network where plural MAPs(Mobile Agent Platforms) exist is provided to enable two MAPs to share information of an MN when the MN has to change an IP address by moving to a neighboring MAP from one MAP while the plural MAPs exist, thus fast IP handoff processing is available. In a network where plural MAPs exist, an IP handoff registration request message is received from an MN(S610). Information on the MN is shared with an MAP which controls a previously positioned area of the MN through a signal packet path for processing IP handoff distinguished from a transmission path of a data packet. Based on the shared information on the MN, the IP handoff is provided to the MN(S612,S614).
