针对数据业务的上行功控算法以及QoS保证

Up Link Power Control Algorithm and QoS Guarantee to Data Service

该文针对高速数据业务传输速率可变、延迟要求不高等特点,对现有系统在传送高速数据业务时的一些弊端进行了分析之后,提出了一种适合在WCDMA中应用的新的上行功率控制方法以及与之相配合的数据传送质量保证措施.仿真证实,新算法有效提高了系统资源利用率,同时还可提高系统在重负载时数据传送质量和新用户的成功接入率.

After analyzing several abuses of transporting data service in existing WCDM A 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.
