A system for supporting an intervention to be carried out by a human operator on a network apparatus of a communication network is provided. The system includes a terminal device provided with a personal proxy, which is part of the equipment of the human operator. The personal proxy provides to the human operator instructions to carry out the various operations of the intervention, by displaying augmented reality elements overwritten to a live view of the network apparatus. Then, upon execution of each instruction, the personal proxy cooperates with the network management system for checking whether the instruction was properly executed, and reports the outcome to the operator by displaying further augmented reality elements overwritten to the live view of the network apparatus.
