Abstract:
1. A method implemented at a base station in a wireless network, the method comprising: measuring a total transmission power associated with calls in a cell of the wireless network, wherein the calls include answered and unanswered calls that originated in the cell; if the total transmission power exceeds a first power threshold, implementing congestion control measures at the base station to reduce the total transmission power below the first power threshold, wherein implementing a congestion control measure on a call includes at least one of muting a downlink voice path of that call, decreasing a data rate of that call, and disconnecting that call, wherein implementing said congestion control measures comprises prioritizing the unanswered calls lower than the answered calls with respect to said congestion control measures, said implementing comprising at least one of: if the total transmission power does not exceed the first power threshold, refraining from implementing said congestion control measures at the base station.
