Up Link Power Control Algorithm and QoS Guarantee to Data Service

  • 摘要: 該文針對(duì)高速數(shù)據(jù)業(yè)務(wù)傳輸速率可變、延遲要求不高等特點(diǎn),對(duì)現(xiàn)有系統(tǒng)在傳送高速數(shù)據(jù)業(yè)務(wù)時(shí)的一些弊端進(jìn)行了分析之后,提出了一種適合在WCDMA中應(yīng)用的新的上行功率控制方法以及與之相配合的數(shù)據(jù)傳送質(zhì)量保證措施.仿真證實(shí),新算法有效提高了系統(tǒng)資源利用率,同時(shí)還可提高系統(tǒng)在重負(fù)載時(shí)數(shù)據(jù)傳送質(zhì)量和新用戶(hù)的成功接入率.
    Abstract: After analyzing several abuses of transporting data service in existing WCDMA system, this paper presents a UL power control algorithm and relevant QoS guarantee. The new algorithm utilized some characteristic of data services, such as its controllable transport speed and low delay need. It is verified by emulator analysis that this algorithm can increase efficiently the utility factor of the system resource. At the same time, it also can improve the quality of communication when the system load is heavy and assure higher ratio of access when a new user try to access to system.
