METHOD FOR REALIZING MOBILE NODE COMMUNICATION IN AN IPV4/V6 HYBRID NETWORK

摘要

A method for realizing mobile node communication in an IPv4/v6 hybrid network, the method realizes mobile communication in the IPv4/v6 hybrid network by setting a mobile IPv4/v6 switching gateway between the IPv4 network and the IPv6 network, the mobile IPv4/v6 switching gateway includes an NAT-PT gateway and a mobile IP application layer gateway that is disposed on the NAT-PT gateway, wherein the NAT-PT gateway configures DNS-ALG. The present invention can sufficiently utilize the existing MIPv4 (RFC3344) and MIPv6 (RFC3775) technologies, effectively solve the problem that existing in the mobile communication of the mobile node in the IPv4/v6 hybrid network, and realize the compatibility of the MIPv4 and MIPv6 technologies, and realize the synchronism of the mobile communication and the network to transit from the IPv4 to the IPv6, the present invention also does not need the existing mobile communication equipments to upgrade too much, and it has very great application value.
