SOLUTION: In the network, in which network nodes each provided with a QoS client are interconnected by a communication network, each QoS client is connected to a QoS server, user terminals are connected to the QoS client. When the user terminal requests the network service, the QoS server informs the user terminal about the service conditions of the network service sent from the QoS server, and the user terminal selects the service condition and designates it to conduct the network service at the service class, corresponding to the selected and designated service conditions.</p> |
