(Before load balancing implementation [August 19, 2012-August 25, 2012], and after load balancing imple- mentation [September 2, 2012-September 8, 2012].) The process of traffic shaping inserts time delays in a TCP/IP data flow for selected active sessions corresponding to high bandwidth usage. Those active sessions are then allocated fewer physical resource blocks (PRBs) on the base station radio, thereby freeing them for other active sessions. Traffic shaping only needs to occur on those base station radios where total usage, as measured by perhaps >80% average PRB usage, indicates heavy radio congestion. The first steps for such a functionality are to determine whether a radio is in congestion and then which mobile devices are actively using that radio.
