A METHOD AND SYSTEM FOR PROVIDING IPV6 SERVICE

摘要

The present invention discloses a system for providing Internet Protocol version 6 (IPv6) services, including a node registration agent for use in applying for a home address for the device, registering the device to a home agent and informing the device of the home address. The present invention also discloses a method for providing IPv6 services, comprising: the device accessing an IPv6 network and acquiring a forwarding address; the device making a remote registration to the node registration agent; the node registration agent applying for a home address for the device, registering the device to the home agent, and informing the device of the home address; the communication counterpart of the device sending messages using the home address as the destination address; the home agent receiving the message and forwarding the message to the forwarding address of the device; and eventually providing the device with the IPv6 services. Application of the system and method reduces the cost, and makes possible the IPv6 services, including the service of supporting roaming from an IPv6 network to an IPv4 network.
