为您有线电视的三网融合业务做好充分准备––来自全球运营商的经验分享KenWright,ARRIS公司首席技术官BillDawson,ARRIS公司业务开发与产品策划部副总裁BobEng,ARRIS公司高级产品管理经理ScottShupe,ARRIS公司技术战略部副总裁EdLotts,ARRIS公司业务部高级经理摘要:因为中国的有线电视运营商开始在其网络中提供“三网融合”(视频/高速互联网/语音)服务,为了保证他们的信号处理设施、网络和技术运维都准备好,还有很多工作要做。提供用户高质量的体验,可靠的服务是保证用户持续忠诚度的最好方法。值得庆幸的是,世界上许多服务提供商都已经成功实现了类似的转变,中国运营商能够受益于他们以往的经验和教训,并将其应用于自身的网络环境中。建设一个胜任三网融合的网络需要对现有网络的性能和物理环境进行评估。在广电总局NGB建设背景下,传输三网融合业务,这项计划中的有线电视领域的现代化改造会带来技术上的机遇和挑战。挑战源于对同轴网络的可靠性要求,要能稳定传输上行信号;机遇来自于许多网络业已完成或进行中的光纤深化改造。有很多现有的技术已经能适合这些应用。除了基础网络评估外,我们还要评估部署三网融合业务的准备工作。一些基本的技术障碍,如一直以来的信号质量问题,以及较复杂的CA集成问题都需要进行分析。另外还有运行维护问题,如网络监控、防护检修、系统升级等等,所有这些技术和运维因素结合在一起,对于运营商要成功开展和维护三网融合业务,是一个非常艰巨的任务。本文将具体探讨为成功开展视频、语音和数据服务,有线网络建设和运营需要准备的几个重点方面。它将总结世界各地已成功开展三网融合服务的运营商经验,并将这些经验应用于中国运营商的特定环境中。第2页共11页编号:时间:2021年x月x日书山有路勤为径,学海无涯苦作舟页码:第2页共11页PrepareyourCATVBusinessforTriplePlayService–ExperiencesfromOperatorsaroundtheWorldKenWright,BillDawson,BobEng,ScottShupe,EdLotts,ARRISAbstract:AsCableTelevisionserviceprovidersinChinaevolvetowardproviding“TriplePlay”offerings(Video,HighSpeedInternet,andVoiceservices)overtheirnetworks,thereismuchtobedoneinordertoensurethattheirsignalprocessingfacilities,networks,andtechnicaloperationsareready.Providingcustomerswithaqualityexperience,andreliableservice,isthebestwaytoensurethecontinuedloyaltyofthosecustomers.Fortunately,manyserviceprovidersaroundtheworldhavesuccessfullymadesimilartransitions,andChineseoperatorscanbenefitfromtheexperiencesandlessonslearnedfromthoseeffortsandapplysomeofthemtotheiruniquesituations.EngineeringaTriplePlaycapablenetworkrequiresevaluationoftheperformanceandphysicalconditionoftheexistingnetwork.TheplannedmodernizationtodelivertripleplayservicesundertheNextGenerationBroadcasting(NGB)initiativebringsbothtechnicalopportunitiesandchallenges.Thechallengesresultfromtheneedtohardenthecoaxialportionofthenetworktocarryupstreamsignalsreliably,whiletheopportunitiesemergefromthealreadydeeppenetrationoffiberinmanylocations.Anumberofexistingtechnologieshavebeenadaptedtothisapplication.Inadditiontothebasenetworkevaluation,assessmentofthereadinesstodeploythesetripleplayservicesshouldalsooccur.BasictechnicalhurdlessuchassignalqualityallthewayuptocomplexissuessuchasConditionalAccessintegrationneedtobeanalyzed.CombiningthesebasictechnicalissueswithotheroperationalissuessuchasNetworkMonitoring,PreventativeMaintenance,Systemupgrades,etc.allcombinetomakeitadauntingtaskforoperatorstosuccessfullydeployandmaintaintripleplayservices.ThispaperwillseektoexploreindetailsomeofthekeyaspectsofpreparingcablenetworksandoperationsforsuccessfuldeliveryofVideo,Voice,andDataservices.Itwilldrawontheexperiencesofserviceprovidersar...
