Secure and seamless WAN-LAN roaming
View Patent ↗Systems and methods are described for secure and seamless roaming between internal and external networks. Double and triple tunnels may be used to connect a mobile node to a correspondent host. A mobile node may include the ability to connect to two networks simultaneously to enable seamless roaming between networks.
1. A method for a mobile terminal to roam between a first network and a second network comprising the steps of:
establishing a first network connection between a first network driver of said mobile terminal and said first network, wherein the first network comprises an internal network;
detecting that a signal strength for the first network connection is below a threshold;
establishing, based on the detected signal strength being below the threshold, a second network connection between second network driver of said mobile terminal and said second network, wherein the second network comprises an external network; and
transitioning communications from said first network to said second network.
2. The method according to claim 1 , further comprising the step of:
establishing a VPN connection using said second network driver.
3. The method according to claim 1 , further comprising:
establishing a VPN connection using said second network driver.
4. The method according to claim 1 ,
wherein the first network comprises a local area network and the second network comprises a cellular network.
5. The method according to claim 1 ,
wherein establishing a second network connection further comprises:
detecting that the first network comprises an internal network and the second network comprises an external network; and
establishing, based on the detecting, a VPN connection over the second network connection.
6. A mobile terminal for roaming between a first network and a second network comprising:
means for establishing a first network connection between a first network driver of a mobile terminal and said first network, wherein the first network comprises an internal network;
means for detecting that a signal strength for the first network connection is below a threshold;
means for establishing, based on the detected signal strength being below the threshold, a second network connection between second network driver of said mobile terminal and said second network, wherein the second network comprises an external network; and
means for transitioning communications from said first network to said second network.
7. The mobile terminal according to claim 6 , further comprising:
means for establishing a VPN connection using said second network driver.
8. The mobile terminal according to claim 6 , wherein the first network comprises a local area network and the second network comprises a cellular network.
9. The mobile terminal according to claim 6 , wherein establishing a second network connection further comprises:
means for detecting that the first network comprises an internal network and the second network comprises an external network; and
means for establishing, based on the means for detecting, a VPN connection over the second network connection.
