WCDMA分布式基站前后臺(tái)同步與主備倒換設(shè)計(jì)與實(shí)現(xiàn)的開題報(bào)告

WCDMA分布式基站前后臺(tái)同步與主備倒換設(shè)計(jì)與實(shí)現(xiàn)的開題報(bào)告摘要WCDMA（WidebandCodeDivisionMultipleAccess）無(wú)線通信技術(shù)已經(jīng)成為目前3G移動(dòng)通信系統(tǒng)中的一項(xiàng)關(guān)鍵技術(shù)。對(duì)于WCDMA分布式基站系統(tǒng)，其前后臺(tái)同步與主備倒換具有重要的意義。本文主要介紹了WCDMA分布式基站前后臺(tái)同步與主備倒換的設(shè)計(jì)與實(shí)現(xiàn)。首先，對(duì)WCDMA分布式基站系統(tǒng)的體系結(jié)構(gòu)進(jìn)行了介紹，重點(diǎn)解析了前后臺(tái)同步與主備倒換的需求和意義。接著，分析了WCDMA分布式基站前后臺(tái)同步和主備倒換的設(shè)計(jì)原則和實(shí)現(xiàn)技術(shù)，包括同步機(jī)制、消息傳遞方式、主備倒換方案等。最后，通過仿真實(shí)驗(yàn)和實(shí)際測(cè)試，驗(yàn)證了該設(shè)計(jì)的可行性和有效性。本文的研究成果對(duì)于WCDMA分布式基站的實(shí)際建設(shè)和運(yùn)營(yíng)管理具有一定的參考價(jià)值。關(guān)鍵詞：WCDMA；分布式基站；前后臺(tái)同步；主備倒換；仿真實(shí)驗(yàn)AbstractWCDMA(WidebandCodeDivisionMultipleAccess)wirelesscommunicationtechnologyhasbecomeakeytechnologyinthecurrent3Gmobilecommunicationsystem.FortheWCDMAdistributedbasestationsystem,front-endandback-endsynchronizationandmain-backupswitchoverareofgreatsignificance.Thispapermainlyintroducesthedesignandimplementationoffront-endandback-endsynchronizationandmain-backupswitchoverforWCDMAdistributedbasestations.Firstly,thearchitectureoftheWCDMAdistributedbasestationsystemwasintroduced,andtherequirementsandsignificanceoffront-endandback-endsynchronizationandmain-backupswitchoverwereanalyzed.Then,thedesignprinciplesandimplementationtechnologiesoffront-endandback-endsynchronizationandmain-backupswitchoverforWCDMAdistributedbasestationswereanalyzed,includingsynchronizationmechanism,messagetransmissionmethod,main-backupswitchoverscheme,etc.Finally,thefeasibilityandeffectivenessofthedesignwereverifiedthroughsimulationexperimentsandactualtests.TheresearchresultsofthispaperhavecertainreferencevalueforthepracticalconstructionandoperationmanagementofWCDMAdistributedbasestations.Keywords:WCDMA;distributedbasestation;front-endandback-endsynchronization;main-backupswitchover;simulationexperiment中英文對(duì)照目錄第1章緒論11.1研究背景與意義11.2研究現(xiàn)狀與進(jìn)展11.3研究?jī)?nèi)容與主要貢獻(xiàn)21.4論文組織結(jié)構(gòu)3Chapter1Introduction41.1ResearchBackgroundandSignificance41.2ResearchStatusandProgress51.3ResearchContentandMainContribution61.4PaperOrganizationStructure7第2章WCDMA分布式基站系統(tǒng)設(shè)計(jì)82.1WCDMA分布式基站系統(tǒng)體系結(jié)構(gòu)82.2前后臺(tái)同步的需求分析112.3主備倒換的需求分析12Chapter2WCDMADistributedBaseStationSystemDesign152.1WCDMADistributedBaseStationSystemArchitecture152.2AnalysisofFront-endandBack-endSynchronizationRequirements192.3AnalysisofMain-backupSwitchoverRequirements20第3章前后臺(tái)同步與主備倒換設(shè)計(jì)原則233.1前后臺(tái)同步設(shè)計(jì)原則233.2主備倒換設(shè)計(jì)原則25Chapter3DesignPrinciplesofFront-endandBack-endSynchronizationandMain-backupSwitchover283.1DesignPrinciplesofFront-endandBack-endSynchronization283.2DesignPrinciplesofMain-backupSwitchover30第4章前后臺(tái)同步與主備倒換實(shí)現(xiàn)技術(shù)334.1同步機(jī)制設(shè)計(jì)與實(shí)現(xiàn)334.2消息傳遞方式設(shè)計(jì)與實(shí)現(xiàn)364.3主備倒換方案設(shè)計(jì)與實(shí)現(xiàn)41Chapter4ImplementationTechnologyofFront-endandBack-endSynchronizationandMain-backupSwitchover454.1DesignandImplementationofSynchronizationMechanism454.2DesignandImplementationofMessageTransmissionMethod484.3DesignandImplementationofMain-backupSwitchoverScheme53第5章仿真實(shí)驗(yàn)與測(cè)試分析565.1仿真實(shí)驗(yàn)設(shè)計(jì)與結(jié)果分析565.2實(shí)際測(cè)試分析與結(jié)果驗(yàn)證60Chapter5SimulationExperimentsandTestAnalysis635.1DesignandResultsAnalysisofSimulationExperiments635.2AnalysisandVerificationofActualTestResults67第6章結(jié)論與展望706.1研究成果總結(jié)706.2不足和改進(jìn)之處716.3
