摘要
当前的移动通信网络,通常由操作维护中心(OMC)、基站控制器(BSC)、基站(BS)和终端用户(UE)四级网元组成。BSC和BS通常称为基站子系统(BSS)。OMC通常由大型的工作站组成,是无线网络的管理核心,它对BSC进行直接的控制和管理。当BSC或BS添加一些新的功能或软硬件升级时,首先要做的是评估新增加的功能对OMC造成的影响。这些影响包括对CPU利用率、存储器(memory)利用率和数据库(database)利用率的影响。在实际测试数据的基础上,提出了OMC CPU利用率的估算方法。利用所提出的估算方法,可以方便地估算其他网元新增加的功能对OMC CPU所造成的影响。
The mobile communication network is usually composed of four kinds of network elements： operation management center （OMC）, base station controller （BSC）, base station （BS） and user equipment （UE）. BSC and BS are called base station subsystem （BSS）. OMC is usually composed of large workstation. It is the center of wireless network management, and takes charge of direct control and management to BSC. While BSC or BS needs additional functions or software/hardware upgrading,the evaluation of the impact of new functions and upgrading on OMC should be carried out. It includes the effects on the utility factors of CPU, memory and database. The method to estimate OMC CPU utility factor is introduced on the basis of the measured data. The impact of the newly added functions of the other network elements on OMC CPU can be estimated easily with this estimating method.
