Busy-Hour Bandwidth Control over Low-ARPU Subscribers (GPRS/UMTS Network)

To alleviate network resource insufficiency during busy hours,
carriers can use busy-hour dual-threshold flow control policies for the
low-ARPU subscribers to ensure resource usage of high-ARPU subscribers.

As shown in Figure 1, when the mobile station (MS) or data card is activated and starts to
access services, the UGW9811 reports daily and monthly traffic volume to
the policy and charging rules function (PCRF). The PCRF delivers
different control policies based on the daily and monthly traffic
volume. If traffic volume during busy hours exceeds a specified daily or
monthly threshold, rates are limited to optimize network resources and
increase carriers revenues.
