Method for realizing dynamic QoS in a WIMAX system includes: a Media Gateway Control MGC makes awareness of a service stream from a Media Gateway MG, and transmits a resource request to a Resource Management Server RMS, which, in response to the request, decides whether there is enough resource; and if yes, confirms the request, and transmits a resource allocation instruction and QoS parameters matching the resource type to a Base Station BS, which, after receiving the instruction, allocates resource to a Subscriber Station SS, thus a channel from the MGC to the MG via BS and SS is established; or if not, refuses the request. According to the method, BS or SS do not make awareness of services, and no bandwidth preservation is needed for UGS or Realtime-polling service streams, and QoS parameters are issued dynamically by a RMS. Thus network resource management is more flexible and convenient.
