With a total of 13 patents to his name, Yokota has made remarkable advancements in network technology, particularly in enhancing security and efficiency.

Latest Patents

Yokota's latest patents include a self-organizing IP multimedia subsystem that features node splitting and merging functions. This innovation allows any node within the subsystem to assume various roles, thereby providing node balancing and fault tolerance to the overall network. Another notable patent focuses on security optimization for IMS/MMD architecture. This mechanism minimizes handoff delay without compromising security, ensuring that media is protected as required by certain applications. The patent outlines methods for mitigating delay during security association re-association and reducing IPSec tunnel overhead for signaling and media at the Mobile Node. In one embodiment, security association keys can be transferred from the old P-CSCF to the new P-CSCF, enabling the establishment of security associations before the Mobile Node physically moves to a new subnet. Proactive handover techniques are utilized in this process.
