The interconnection system comprises at least one preferably mobile communication device which can be connected to a remote data system by a communication channel enabling firewalls to be by-passed. The communication device comprises means for emitting presence signals. A service component of the communication device establishes a communication channel to a remote service agent of the remote data system, that is assigned thereto. The service component of the communication device indicates its presence at regular intervals by notification signals to the remote service agent in order to keep the communication channel active. The period of the notification signals is defined by the remote service agent at least once after the channel has been established. The remote service agent can then send messages in real time to the service component.
