    • Systems and methods for providing adaptive fine-grained fair usage controls are provided. Rather than providing a fixed fair usage threshold having time and data volume for all subscribers in the network, a quota manager at the policy controller defines an initial fair usage window having a longer period of time and higher data volume. When a subscriber exceeds the initial window, the quota manager provides a smaller time period and lower data volume. The quota manager continues to adapt the fair usage window in this way until a violation of the fair usage threshold is detected. The adaptive fair usage windows may be based on subscriber profile information, subscriber session information, and/or prior subscriber usage history.
