All-IP IPv6 System Terminal Home Agent Method and Recording Medium for IPv6-based Communication in All-IP environment

摘要

The present invention relates to a technique for registering and querying an IPv6 address with a user identifier using an existing mobile IP infrastructure in an All-IP environment to enable communication between the terminals, and the All- A method for IPv6 address based communication in an IP environment includes the steps of: (a) receiving, at a home agent (HA), registration request information including at least a user identifier and a current IPv6 address from a terminal through a registration request message; Registering each information of the registration request information in association with each other; (b) storing information registered in the HA in a database; And (c) when the user identification server receives the IP address request information including at least the other party identifier from the terminal through the IP address request message, searches the database for the IPv6 address corresponding to the received counterpart identifier, And providing the same.
