As more and more new Internet applications appear, the amount of traffic types requiring different QoS parameters of mobile network grows as well. To guarantee appropriate level of service quality mobile network operators need an intellectual mechanism of bandwidth redistribution and relevant charging of broadband subscribers. As a 3GPP-compliant PCRF (Policy and Charging Rules Function) PROTEI Policy Controller allows to change properties of data channel allocated to a subscriber and apply charging rules dynamically during Internet session. As a result, 3G or LTE network equipped with PROTEI Policy controller adapts its characteristics according to changing external conditions (network overloads, traffic mix change and so on) for the most effective monetizing of mobile broadband network infrastructure.
About PROTEI Policy Controller
PROTEI Policy Controller is an intellectual node regulating policy and charging parameters of mobile broadband subscribers in 3G and LTE networks. Equipped with a flexible and easy-to-manage policy decision engine PROTEI Policy Controller allows to implement mobile network operator’s business need in policy and charging rules providing dynamic distribution of limited broadband network resources. Policy and charging control in modern networks implies dynamic per-service modification of available bandwidth and money debiting rules during ongoing Internet session depending on the type of service, subscriber profile parameters, subscriber historical data, date and time and commands from external systems like subscriber portal. Besides data channel parameters control PROTEI Policy Controller allows to manage content-filtering rules for the subscribers providing parental control or corporate control services.
