The invention discloses an uplink bandwidth allocation method of a broadband wireless access system. In this method, firstly, the base station according to the user station traffic service quality parameters and historical connection state to calculate the user station next uplink sub frame expected bandwidth allocation parameters, and according to the parameters of the bandwidth parameter updating subscriber station the uplink sub frame, as a bandwidth parameter of uplink sub frame; then the next uplink sub frame bandwidth parameter stands to the user interface bandwidth according to the system parameters are updated again, and will be updated again after the bandwidth parameter corresponding to the base station in an uplink sub frame for users on the station distribution of the actual bandwidth. The invention uses dynamic bandwidth allocation based on full consideration of the quality of service parameters of the business, according to the distribution of quality of service requirements of different business decisions for each subscriber station bandwidth, effectively ensure the quality of service, broadband wireless access application environment is more suitable for multi service.
