Patent ID: 8520523

Claim:
A method ( 500 ) of dynamically adjusting QoS levels for bearers in a communication system configured to enable users to communicate with a public domain network (PDN), each bearer transporting a subset of packets transmitted from the PDN to users at a specified quality of service (QoS) level among a plurality of QoS levels, the method comprising: receiving ( 510 ) a global throughput and bearer throughputs corresponding to the bearers; individually, for each bearer, determining ( 520 ) whether a QoS level associated with the bearer is adequate by comparing the global throughput with threshold values associated to the bearer and on evaluating whether the bearer is overloaded; and setting ( 530 ) the QoS level associated with the bearer to another level among the plurality of QoS levels, when the determining indicates that the QoS level associated with the bearer is not adequate.
