A scheduling scheme for the heterogeneous multimedia services in mobile broadband systems

As the development of the third generation mobile systems proceed, researchers are turning their attention to the integration of multimedia service under the wired and wireless environments. One challenging requirement is that mobile systems convey information of diverse types including voice, computer data, facsimile, and video data which has different quality of service constraints. Basically, a centralized control scheme for a coordinated multiple access is required in order to efficiently accommodate multimedia traffic on wireless links. The proposed scheme dynamically scheduling the mobile terminal which has data to transfer according to the service types at the base station. In this scheme, we select the key point of the quality of service as the time constraint between transmission intervals. Simulation results show that exploiting the information on the timestamp in the transmission terminal scheduling is a good solution in respect to delay sensitive services
