Fuzzy Logic for QoS Control in IMS network

The nature of the services provided by IP Multimedia Subsystem (IMS) networks require a maximum quality, this will appear in service provisioning for differentiate between the added value of IMS and other classical case as well as Internet. Toward, the QoS management mechanisms focus primarily on resource reservation in service provisioning, all this specification are introduced by 3GPP standards. Although, all proposed mechanisms haven’t any entity overseeing and monitoring services after supply. For that in this work, we propose a new approach QoS monitoring based on fuzzy logic. The technique allows modelling a control system able to identify any QoS deterioration in real-time, also a rapid resources reconfiguration and restoration to ensure customer satisfaction IMS.
