| Abstract(in English) | In the next-generation All-IP mobile network, it is required to maximize the system capacity as well as to guarantee QoS for various data services by controlling radio resources effectively. In wireless environment, link quality differs from one user to another and changes very rapidly, causing the QoS and the system capacity dependent on the link adaptation method and transmission order controlled by the packet scheduler. However, conventional packet schedulers treated the QoS guarantee and the maximization of the system capacity separately and did not achieve both of them. This paper proposes a packet scheduler that satisfies both of the two requirements, by adaptively allocating time-slots according to the wireless link quality and required QoS level. We evaluate the effectiveness of the proposed packet scheduler by computer simulation, assuming the high-speed downlink packet access (HSDPA) defined in the 3GPP Release 5 specifications as a wireless link. It is confirmed that the proposed packet scheduler can increase the system throughput by 80% compared with the conventional QRR (Quasi-Round Robin) packet scheduler. |
