Abstract
An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and operable to receive a plurality of packets associated with a communications flow, the packets including a plurality of subrates. The cell site element is further operable to detect a congestion condition via a measurement of a level in a receive jitter buffer. When the congestion condition exists, individual subrates can be dropped from subsequent backhaul packets until congestion subsides. In more particular embodiments, the cell site element can be informed that congestion exists, whereby a congestion level is assigned to a collection of the subrates. In addition, the cell site element prioritizes the subrates and removes individual samples from one or more of the packets; high priority calls and critical radio control information are not affected during the congestion condition.
