Abstract
The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node.

Claim
1. A mobile node capable of being redirected to a first node, which was selected when the mobile node initially attached to an access system supporting network-based mobility, the mobile node comprising:
a transmitter which, in operation, transmits to a second node an Internet Key Exchange (IKEv2) request message to establish a security association with the second node when the mobile node, which is attached to the access system supporting network-based mobility and for which the first node was selected, switches to attach to an access system supporting client-based mobility, the IKEv2 request message including a Network Access Identifier (NAI) of the mobile node having a network prefix assigned to the mobile node, wherein the second node discoverable by the mobile node in the access system supporting client-based mobility is different from the first node; and
a receiver which, in operation, receives from the second node an IKEv2 response message including redirect information containing one of an IP address of the first node and hints, the hints including at least one of an address prefix and a domain name and allowing the mobile node to derive a valid address for the first node, the valid address including one of an anycast group address, a multicast group address, and a unicast address;
wherein the transmitter, after the receiver receives the IKEv2 response message when the mobile node is attached to the access system supporting client-based mobility, transmits an IP address registration request to the first node using the IP address of the first node to register a new address with the first node to establish a new security association with the first node, to which the mobile node is re-directed.
2. The mobile node according to claim 1, wherein the transmitter transmits the IKEv2 request message to the second node using an anycast address, a multicast address, or a unicast address of the IKEv2 request message.
3. The mobile node according to claim 1, wherein the transmitter transmits the IP address registration request to the first node using the hints contained in the redirect information included in the IKEv2 response message.
