METHOD FOR PROVIDING AN ABILITY OF ROAMING FROM IPV6 NETWORK BASED ON NEMO TO IPV4 NETWORK

摘要

The present invention relates to network communications, and more particularly, to a method for providing mobility to a mobile network moving from a mobile IPv6 network environment to an IPv4 network environment.;The method for providing mobility of a mobile network according to the present invention includes obtaining and storing IPv6 and IPv4 addresses of a tunnel agent (TA) existing between a mobile IPv6 network environment and a mobile IPv4 network environment, and storing them in a mobile router (MR); Acquiring an IPv4 care of address (MR) of a mobile router (MR) that has moved from the mobile IPv6 network environment to the mobile IPv4 network environment, and a flag indicating that the mobile router (MR) has moved to the IPv4 network environment is set. Transmitting a binding update message for forming a tunnel between the mobile router (MR) and the tunnel agent (TA) and a tunnel between the tunnel agent (TA) and the home agent (HA) and based on the binding update message. Forming a tunnel between the MR) and the tunnel agent (TA) and a tunnel between the tunnel agent (TA) and the home agent (HA). And that is characterized.;IPv4 Network, IPv6 Network, Mobile Network, NEMO, Tunneling
