Latest Patents

One of Babin's latest patents involves a method for using a transmission control protocol (TCP) channel to save power for VPNs that utilize user datagram protocol (UDP). This innovative approach allows for maintaining a VPN connection between a mobile device and a server over a wireless network while conserving the device's power supply. The method is particularly beneficial for connections that require server-initiated traffic. After a successful login to a VPN server, a VPN client establishes both TCP and UDP connections. If a power timeout occurs, the server calculates the elapsed time since the last tunnel traffic. If this time exceeds a specified power timeout value, the server sends a control message to the client via the TCP channel, prompting the client to reestablish the UDP connection and resume transmission.

Another notable patent addresses the pausing of keep-alive messages and roaming for VPNs on mobile devices to save battery power. This method conserves the power supply by halting periodic roaming scans and keep-alive messages when there is no traffic between the mobile device and the server for a specified idle time. Once traffic resumes, the mobile device connects to the highest priority network and resumes the necessary scans and messages.
