Patent number: 11477634Abstract: 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.Type: GrantFiled: January 20, 2021Date of Patent: October 18, 2022Assignee: Sun Patent TrustInventors: Kilian Weniger, Takashi Aramaki, Jun Hirano, Jens Bachmann, Shinkichi Ikeda
