Method for controlling up-link flow

The invention provides a of ascending flow control method, the key lies in that the establishment of a gradual factor, take the product of IUB residual flow of base stations nodes (NodeB) and gradual factor as a control to distribute IUB flow incremental value to user equipment (UE). NodeB first obtain the predistribute IUB flow incremental value according to the flow scheduling algorithm, and calculate the empty flux according to size information of data packet the UE uploaded; NodeB obtains the IUB flow incremental value distribute to UE according to empty flow, gradual factor and predistribute IUB flow incremental value, finally notice to UE the distributed IUB incremental flow value. Use the scheme of this invention can gradually release the remaining IUB flow resources, control the distribution of IUB incremental flow value to UE, balance empty flow and IUB flux, prevent obstruction of IUB interface and overflows the cache phenomenon.
