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. An integrated circuit comprising circuitry configured to control a process of a mobile node, the process comprising:
transmitting, when changing the mobile node's mobility management scheme from a network-based mobility management scheme to a client-based mobility management scheme, to a second node, which is discoverable in the client-based mobility management scheme, an Internet Key Exchange (IKEv2) request message to establish a security association with the second node, wherein the mobile node prior to changing the mobility management scheme is attached to a network including a first node, which is supported in the network-based mobility management scheme and is selected for the mobile node, and the IKEv2 request message includes a Network Access Identifier (NAI) of the mobile node having a network prefix assigned to the mobile node, receiving, 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 of the first node, the valid address including one of an anycast group address, a multicast group address, and a unicast address, and transmitting an IP address registration request to the first node, to which the mobile node is redirected, using one of the IP address of the first node and the hints contained in the redirect information included in the IKEv2 response message to register a new address with the first node to establish a new security association with the first node.
2. The integrated circuit according to claim 1, wherein the second node is different from the first node.
3. The integrated circuit according to claim 1, wherein the IKEv2 request message is transmitted to the second node using an anycast address, a multicast address, or a unicast address.
