摘　　要：以客户为中心的业务级网络管理目前正成为国际上研究的热点,业务资源管理是其中的关键部分。为了提高业务资源的利用率,必须有一套可对业务资源利用率进行量化的评价模型。论文提出了一种新的业务效用模型SUM,运用该效用模型可以使业务提供商(SP)和网络运营商(NO)结合自身盈利和用户感受定量地对业务资源管理进行评价,帮助SP和NO通过不同的方式分析业务资源管理性能,呈现资源管理参数设置与业务效用之间的关系,发现业务资源管理瓶颈从而最终提高资源利用效率。论文把该效用模型应用于自适应业务资源管理中,仿真结果表明,SUM模型可以很好地定量地反映业务资源的利用率,选取该效用模型作为自适应原则显著提高了系统的资源利用整体效率。Recently,Service Resource Management （SRM）,a key part of customer-oriented Service Level Management （SLM）,has been making significant development.A measurable service resource utility evaluation model is necessary to improve the service resource effficiency.This paper proposes SUM,a new mobile service utility model,which can benefit SP and NO by getting quantitative evaluation of SRM based on both the profit of themselves and the satisfaction of the customer,analyzing the performance of SRM via various methods,revealing the relationships between resource management parameters and service utilities,locating the bottlenecks of SRM,and finally improving the resource utilization efficiency.This paper also adopts SUM in the self-adaptive SRM,and the simulation result shows that the service resource utility can be exactly reflected by SUM and the system efficiency is greatly increased by taking SUM as the adaptive rule.

关 键 词：通信技术 业务效用 业务资源管理 自适应资源分配
