A method performed at a gateway having a connection to a network, the method comprising:
- detecting disruption of the connection to the network;
- after intercepting a HTTP request from a user device having a first connection to the gateway and a second connection to the network, returning a web page to the user device, the web page comprising a tunnel setup information for establishing a tunnel between the gateway and the user device;
- and
- establishing the tunnel between the gateway and the user device as a communication backup link to the network.
A device comprising
- a first link interface configured to provide a connection to a network;
- a second link interface configured to provide a first connection to a user device, wherein the user device has a second connection to the network;
- a processor configured to;
- determine a disruption of connection to the network;
- send a web page to the user device after having intercepted a HTTP request from the user device, the web page comprising a tunnel setup information for establishing a tunnel between the gateway and the user device;
- and
- establish the tunnel between the device and the user device as a communication backup link to the network.
A non-transitory computer readable storage medium comprising program code instructions executable by a processor for:
- detecting disruption of a connection of a gateway to a network, wherein a user device has a first connection to the gateway and a second connection to the network;
- after intercepting a HTTP request from the user device, returning a web page to the user device, the web page comprising a tunnel setup information for establishing a tunnel between the gateway and the user device;
- and
