提出了一种基于统一的电信管理网需求、分析、设计(UTRAD)方法学的性能测量项定义方法.采用分阶段定义流程,不但定义了每一阶段具体的行为和步骤,以及参与定义过程的实体在各个阶段的作用,覆盖了各层面相关的性能测量需求,而且定义了将性能测量需求转化为可在网元上测量的性能测量项的方法.通过比较可以看出.该方法继承了已有的性能测量项定义方法的优点,在摒弃了其中一些不合适部分的同时,增加了新的内容.
A new method of the performance measurement definition is presented based on unified telecommunication management network ( TMN ) requirements, analysis and design ( UTRAD ) methodology. The method including four steps describes the action and process of each step, introduces the measurement definition communities and their roles in each step, and meets the performance measurement requirements of evervy management layer. It also indicates how the performance measurement requirements can be transformed into the performance measurements. Compared with the existingmethods, meanwhile, the method inherits some useful properties from the existing methods, abandons some improper properties and presents some new properties.
