METHOD FOR CONTROLLING BANDWIDTH USAGE IN WIRELESS NETWORK AND SYSTEM FOR CONTROLLING VIDEO DATA RATES IN WIRELESS NETWORK, AND SYSTEM FOR ENFORCING NETWORK POLICIES

PROBLEM TO BE SOLVED: To adjust a data rate for video data being transmitted through a wireless network based upon a congestion level in a cell.SOLUTION: A network monitoring system identifies congestion levels in network cells based upon data traffic captured from network interfaces. When a cell congestion level reaches a first threshold, a first alert is sent to a video transcoding device. The video transcoding device adjusts the data rate for video data being sent to one or more subscribers in the congested cell. The data rate adjustment may be based upon a subscriber profile or a user equipment type. When the cell congestion level drops below a second threshold, the network monitoring system sends a second alert indicating that the data rate can be increased.
