ABSTRACT:
Traffic in a radio communication system (FIG. 1) is adaptively balanced (300) to control congestion. A congestion model is maintained (302) with congestion dependencies including first and second types of congestion along with corresponding likelihood functions that indicate a likelihood that the first type of congestion will lead to the second type of congestion. An early warning of an impending congestion is detected (304) from an incoming traffic mix which exceeds an output traffic capability, given a current output allocation and configuration. The congestion model is accessed (306), in response to detecting the impending congestion, to identify and determine a priority for possible sources of the impending congestion. Action is then taken (308, 314, 318) to relieve the impending congestion by doing at least one of (a) increasing output resources and (b) decreasing traffic rates from the possible sources, prioritized in accordance with the congestion model.
