62, whether the signaling number whether the CPU occupation rate that judges treatment S CTP signaling is greater than the first thresholding and/or treatment S CTP is greater than the second thresholding.
ENB obtains after the CPU occupation rate and/or treatment S CTP signaling message number for the treatment of S CTP signaling, carry out congested differentiation, when the CPU of described treatment S CTP signaling occupation rate is greater than the first thresholding, and/or the signaling number for the treatment of S CTP is while being greater than the second thresholding, shows system congestion.When system congestion, need to carry out congestion control processing, when ensureing large signaling traffic, eNB normally works.
Arranging of the first thresholding and the second thresholding can be carried out pre-configured according to system processing power.The embodiment of the present invention does not limit the setting of the first thresholding and the second thresholding.
Concrete, the signaling number for the treatment of S CTP can be the SCTP signaling number of processing per second, the first thresholding value is that 85%, the second thresholding value is 3500 bag/seconds (they being the signaling bag of processing per second).
In the time only carrying out congested differentiation by the CPU occupation rate of processing SCTP signaling, be specially: in the time that the CPU occupation rate for the treatment of S CTP signaling is greater than 85%, judgement system, in congestion state, need to carry out congestion control; In the time only carrying out congested differentiation with the signaling number of processing SCTP, be specially: in the time that the signaling number for the treatment of S CTP was greater than for 3500 bag/second, judgement system, in congestion state, need to carry out congestion control.When counting these two conditions while carrying out congested differentiation with processing the CPU occupation rate of SCTP signaling and the signaling for the treatment of S CTP, be specially: when the CPU occupation rate for the treatment of S CTP signaling is greater than 85%, while being greater than for 3500 bag/second with the signaling number for the treatment of S CTP, judgement system, in congestion state, need to carry out congestion control.
