Method of establishing a connection on a communication network

A communication device connectable to a requesting communication device by means of a communication network, comprising:

• a receiver adapted to be connected to the network for receiving, in a first operating condition, a network signal indicating the network availability to establish said connection and a terminal signal requesting the availability to run an application exchanging data between the communication device and the requesting device, comprising:
• an elaborating device associated with the receiver adapted to receive an application response signal representative of the availability/unavailability of the communication device to run the application, the elaborating device being further adapted to elaborate the network signal and the application response signal so as to generate a response signal carrying information indicative of the availability/unavailability of the network to establish the connection combined with the availability/unavailability of the communication device to run the application;
• and
• a transmitter associated with the elaborating device for sending on the network and toward the requesting device the response signal,
• wherein said information is capable of assuming a first value corresponding to a first state of said first operating condition in which the network is available to establish the connection and the communication device is unavailable to run the application, in such first state the response signal being suitable to produce the releasing of resources reserved by the network for establishing the connection.

A communication system comprising a first terminal, a second terminal and a communication network for establishing a connection between the first and the second terminals, the second terminal comprising:

• a receiver connected to the network for receiving a network signal indicating the network availability to establish said connection and a terminal signal requesting the availability to run an application exchanging data between the first and the second terminal;
• the second terminal comprising:
• an elaborating device associated with said receiver adapted to generate an application response signal representative of the availability/unavailability of the second terminal to run the application;
• the elaborating device being adapted to elaborate the network signal and the application response signal so as to generate a response signal carrying information indicative of the availability/unavailability of the network to establish the connection combined with the availability/unavailability of the second terminal to run the application;
• and
• a transmitter associated with the elaborating device for sending on the network and toward the first terminal the response signal carrying said information,
• wherein said network comprises a plurality of nodes predisposed for carrying out the connection, when said information is capable of assuming a first value corresponding to a first operating state in which the network is available to establish the connection and the second terminal is unavailable to run the application, in such first state said response signal being suitable to produce the releasing of resources reserved by the network for establishing the connection.
