Method and system for managing mobile router in proxy mobile internet protocol version 6 domain

A method for managing mobile routers in a PMIP6 (proxy mobile internet protocol version 6) domain, comprising:

• registering profile information in a profile server, the profile information containing mobile network prefixes managed by mobile routers;
• when an arbitrary mobile router is connected to an arbitrary MAG (mobility access gateway) within the PMIP6 domain, providing profile information of the connected mobile router from the profile server to the MAG;
• extracting a mobile network prefix from the profile information and providing a registration message containing the mobile network prefix from the MAG to an LMA (local mobility anchor), for registering the mobile network prefix;
• setting up, at the LMA, forwarding information of a mobile network managed by the mobile router, and sending a response message in response to the registration message from the LMA to the MAG;
• and
• establishing a tunnel between the MAG that receives the response message and the LMA, and setting up forwarding information of the mobile network, wherein the step of providing profile information of the connected mobile router from the profile server to the MAG includes requesting the profile server to provide the profile information of the mobile router, and the MAG determines whether a mobile network prefix exists in the profile information provided by the profile server, and if the mobile network prefix is in the profile information, the MAG recognizes a mobile node as a mobile router.

A system for managing a mobile router connected to a PMIP6 (proxy mobile internet protocol version 6) domain, comprising:

• a MAG (mobility access gateway) to which the mobile router is to be connected;
• and
• an LMA (local mobility anchor), connected to the MAG, for managing location information of the mobile router and packet forwarding information of the mobile router, wherein
• the MAG determines whether a mobile network prefix exists in a profile server, and if the mobile network prefix is in the profile server, the MAG recognizes a mobile node as a mobile router, and, when the mobile router moves from an arbitrary MAG to another MAG within the domain, the LMA sends a de-registration message to deregister the home prefix of the mobile router and the mobile network prefix set up in the arbitrary MAG.
