摘要： A method for scheduling radio resource allocation among active flows within a wireless communication network (100) is proposed. The method comprises, at each working period of the scheduling method, the following steps. For each active flow, the presence of priority data to be transmitted within the current working period is checked (205) based on a comparison between data queued at a reference working period before the current working period and data transmitted between the reference working period and the current working period. Each active flow having priority data to be transmitted within the current working period is classified (205) as priority active flow. The remaining active flows are classified (210) as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated (220) among the priority active flows, and the corresponding priority data are transmitted (225) over the respective allocated resources. After completing priority data transmission, the radio resources are allocated (245) among the non-priority active flows and the corresponding non-priority data are transmitted (250) over the respective allocated radio resources until the end of the current working period.
