Embodiment Construction
[0039] The invention can fairly allocate bandwidth among UGS, rtPS, nrtPS, ertPS and BE services, and guarantee the QoS characteristics of various services.
[0040] In the WiMAX system, a special functional module (uplink bandwidth allocation module) is designed to realize the functions of uplink scheduling and bandwidth allocation; the uplink bandwidth allocation method that the present invention relates to is exactly applied to the bandwidth allocation for data transmission in the uplink bandwidth allocation module.
[0041] Image 6 A system architecture diagram involved in the present invention is shown. The input of the uplink bandwidth allocation module 1 includes: the bandwidth request message queue provided by the uplink data distributor 4 and the GMSH subheader of the data PDU, information such as the CID and QoS parameters of the current service flow provided by the service flow management module 2, and the channel description module 3 provides the current status inf...
