Abstract

This invention relates to a method in a communication system comprising a gateway and a server. The method comprises: sending a request for establishment of a communication tunnel from the gateway to the server; transmitting a secret from the server to the gateway in response to receiving the request in the server; establishing a communication tunnel by connecting a tunnel client in the gateway to a tunnel server in the server using the received secret; receiving data from a device connected to the gateway and transmitting at least a portion of the data to the tunnel server via the communication tunnel.

Claims15

Dependent claims

A method in a communication system, said system comprising a gateway and a server, said method comprising:

sending a request for establishment of a communication tunnel between the server and the gateway;
transmitting a secret from the server to the gateway;
establishing a communication tunnel by connecting a tunnel client in the gateway to a tunnel server in the server using the received secret;
receiving, at a first input on the gateway, data from a device connected to the gateway;
categorizing, at the gateway, the data received from the device in to at least a first and a second category based on the content of the received data;
transmitting at least a portion of the data to the tunnel server via the communication tunnel, wherein the portion of the data transmitted to the tunnel server comprises the first category of data, and the second category of data is not transmitted to the tunnel server;
receiving a signal at a second input on the gateway;
and
disabling communication via the communication tunnel on a condition that the signal on the second input corresponds to a predetermined signature.
