当前的无线通信网络,通常由4级节点组成,从卜到下分为:操作维护计算机(OMC)、基站控制器(BSC)、基站(BS)和移动终端(MS);OMC控制着BSC,而BSC控制着BS,BS和最末端的移动站(MS)相连;OMC控制着整个网络的运行状态.而重同步义是一种最重要的状态控制;它是BSC每隔一定的时间间隔向OMC报告网络的运行状态,这些状态包括告警(Alarm)和状态变化(State)信息,网络管理人员根据这些状态信息对全网的运行情况进行监控;从设备演变的几个版本来看,重同步的设计要求是:在基本负荷下,要在70s左右完成重同步过程;而在操作负荷下要在100s左右完成重同步过程;但这次升级后的版本在现场测试中发现重同步的时间是303s;针对这个问题,采用理论分析和实验室实际测试的方法,逐步对重同步的各个环节进行分析,最终发现了软件设计缺陷,并提出了实际的改进方案,纠正了这个设计缺陷.
噹前的無線通信網絡,通常由4級節點組成,從蔔到下分為:操作維護計算機(OMC)、基站控製器(BSC)、基站(BS)和移動終耑(MS);OMC控製著BSC,而BSC控製著BS,BS和最末耑的移動站(MS)相連;OMC控製著整箇網絡的運行狀態.而重同步義是一種最重要的狀態控製;它是BSC每隔一定的時間間隔嚮OMC報告網絡的運行狀態,這些狀態包括告警(Alarm)和狀態變化(State)信息,網絡管理人員根據這些狀態信息對全網的運行情況進行鑑控;從設備縯變的幾箇版本來看,重同步的設計要求是:在基本負荷下,要在70s左右完成重同步過程;而在操作負荷下要在100s左右完成重同步過程;但這次升級後的版本在現場測試中髮現重同步的時間是303s;針對這箇問題,採用理論分析和實驗室實際測試的方法,逐步對重同步的各箇環節進行分析,最終髮現瞭軟件設計缺陷,併提齣瞭實際的改進方案,糾正瞭這箇設計缺陷.

The mobile communication network is usually composed of four network element: Operation Management Center (OMC), Base Station Controller (BSC), Base Station (BS), User Equipment (UE) from up to down separately. OMC controls BSC, BSC controls BS, and BS connects with MS, which is at the end of mobile communication network. OMC is in charge of the whole network function, and re-synchronization is the moat important state controlling. The requirement of re-synchronization is: it should be finished in 70 seconds in the situation of basic load and 100 seconds in the situation of operating load. But it is engaged attention that the re-synchronization time is 303 seconds after the updating. To solve this problem, we analysis the situation in theory and validate it in practice in each step of re-synchroniza-tion, and find out the problem of software. Then a amendatory scheme was proposed.
