[0012] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0013] The core idea of the present invention is to detect the transmission status of the Iub port, and if congestion occurs, the data frame is dropped with a certain probability to ensure the priority transmission of the control frame. In this way, the normal interaction of the control plane can be ensured, and the high-level retransmission mechanism can be used to maintain data plane communication, avoiding burst services and reducing the probability of FP out-of-step.
[0014] In practical applications, the present invention can be implemented on the NodeB and RNC sides. In this way, the uplink and downlink can simultaneously prevent FP out-of-step, or it can be implemented in only one of the network elements to prevent FP out-of-step ...
