Method of flow control for IUB-interface, apparatus and base station
A method of flow control for an IUB-interface, an apparatus, and a base station are disclosed. The method includes the following steps: a frame loss rate of a service is acquired according to the number of lost frames in a predetermined period. A congestion condition at the IUB-interface is determined according to the frame loss rate. A total bandwidth allocated to users' IUB-interface is adjusted according to a bandwidth reservation margin. It is determined whether congestion occurs at the IUB-interface or not by calculating the frame loss rate in the predetermined period, and a maximum available bandwidth for the users' IUB-interface is adjusted in real time according to the congestion condition. Therefore, congestion can be controlled effectively and the bandwidth of the IUB-interface can be used sufficiently.
