摘要： A method, apparatus, and computer program product for responding to congestion levels in a communication system by rate adaptation. A congestion condition is indicated by marking data packets. In response to receiving an indication of congestion, a data rate is reduced. A rate reduction inhibit timer is started, and further rate reduction is initiated if congestion is indicated after the rate reduction inhibit timer has expired. A rate increase timer is used to initiate a rate increase if no indication of congestion is received during a rate increase time.

摘要： A method, apparatus, and computer program product for indicating and responding to various congestion levels in a communication system, such as a wireless communication network. A congestion level in the network is determined, and a percentage of data packets to be transmitted to an endpoint, such as user equipment or another network endpoint serving the user, are marked to indicate the congestion level. The endpoint determines the congestion level at the network from the percentage of received data packets that are marked and may initiate an appropriate response behavior in response to the determined congestion level.

摘要： A method for reducing congestion in a wireless communication network is presented. The method includes monitoring a congestion level of at least one network node of the network. When the congestion level is greater than a first threshold, the method includes initiating a first congestion control mechanism. When the congestion level is greater than a second threshold, the method includes initiating a second congestion control mechanism, the second threshold being greater than the first threshold. In some implementations, the first congestion control mechanism includes codec rate adaptation (CRA), and the second congestion control mechanism includes at least one of rejecting new service requests and dropping existing services. The method may include, after initiating the first congestion control mechanism, starting a timer and, when the timer reaches a pre-determined value and the congestion level is greater than the first threshold, initiating the second control mechanism.
