| Abstract(in English) | With the rapidly increasing demand for high-speed mobile multimedia and the need to support diversified requirements of users by packet communication systems, wireless Quality of Service (QoS) resource management becomes more and more indispensable, especially for the JMT-2000 system and beyond. In recent researches, independent QoS controls at base stations have been proposed considering traffic types and available radio resource allowing neighboring cell interference. However, in a CDMA packet communication system, channel capacity in a cell varies dynamically due to the variant interference level from the neighboring cells, QoS satisfaction and the system capacity may not be optimized while considering the entire system by conventional schemes. In this paper, the essential elements of wireless QoS control are denoted and a wireless QoS resource management for packet mobile communications with base station power resource cooperation control is proposed. Computer simulation indicates that the QoS satisfaction rate and the system capacity are improved remarkably by the proposed scheme. The improvement becomes ever larger when realtime and nonrealtime traffic distributed in an unbalanced manner, which further elucidates the effectiveness of the proposed resource cooperative control scheme. |
