中国电信相关系统缩略语BSS:Business support system 业务支撑系统OSS:Operation support system 运营支撑系统MSS:Management support System 管理支撑系统(前二者又合称BOSS:Business and Operation support system ,电信业务运营支持系统)在企业(特别在是电信行业)IT战略规划中占据了重要地位的三大支柱内容.对于BOSS，面对客户是统一的；面对电信运营商，它融合了业务支撑系统(BSS)与运营支撑系统(OSS)，是一个综合的业务运营和管理平台，同时也是真正融合了传统IP数据业务与移动增值业务的综合管理平台。

BSS是面向运营商业务和服务的，而OSS是对BSS提供技术（特别是计算机技术）支撑和管理的。

有了BSS才会有OSS。

从辩证法角度看，BSS 决定OSS，但OSS对BSS起反作用，二者缺一不可。

BSS往往指计费、结算、帐务、客服、营业等系统OSS往往指网管、网优等系统OSS/BSS 是电信运营商的一体化、信息资源共享的支持系统，它主要由网络管理、系统管理、计费、营业、账务和客户服务等部分组成，系统间通过统一的信息总线有机整合在一起。

它不仅能在帮助运营商制订符合自身特点的运营支撑系统的同时帮助确定系统的发展方向，还能帮助用户制订系统的整合标准，改善和提高用户的服务水平。

作为一种高效的信息管理系统，OSS/BSS已在国外电信运营商中得到广泛的运用，并在实践中积累了大量的成功案例。

OSS /BSS解决方案也在这一过程中趋于完善。

但国内目前还没有成熟的OSS/BSS系统，电信运营商的网管系统、计费系统、营账系统、客服系统等都是各成体系，没有经过有机整合。

目前全球领先的OSS/BSS供货商主要有Tibco、Portal、HP、Concord、Syndesis、SUN、Micromuse等。

思科、亚信、同天等厂商还在国内开放了OSS/BSS 实验室。

BSS:Business support system 业务支撑系统OssOSS:Operation support system 运营支撑系统MssMSS:Management Support System 管理支撑系统(前二者又合称BOSS:Business and Operation support system )三者在电信企业的规划中占据了重要地位的三大支柱内容.OSS和BSS有什么区别和联系不同的行业机构会对ＯＳＳ和ＢＳＳ有自己的界定．比如计费，按照不同机构的划分可能会落在ＢＳＳ的范围，也可能会跑到ＯＳＳ那边去．ＢＳＳ更多的是指客服，ＣＲＭ，以及ＢＩＬＬＩ；ＯＳＳ则更多和网络那边有关．当然，还有ＭＳＳ的说法了，这就往ＢＩ这个方向走了－但ＢＩ这东西国外某些机构也会放在ＢＳＳ里面．OSS，Operation Support System，BSS，Business Support System，打个比方，BSS 是为销售服务的，目的就是如何从客户哪里赚到钱，并且赚钱后还要他们很满意，这样以后还是会乖乖的继续掏钱；OSS是工程师用的，是确保企业的生产系统能够按照销售下的订单，按时、按量、并且保障质量的提供服务给客户。

BSS往往指计费、结算、帐务、客服、营业等系统；OSS往往指网管、网优等系统。

现在很难将OSS/BSS严格的界定，有些模块可以算在BSS,也可划在OSS，还有些模块的一部分可以被划为OSS或BSS，例如计费就是这样。

BSS往往指计费、帐务、客服、营业、客户关系、BI等系统OSS往往指计费、结算、网管、资源、网优等系统不同的运营商理解也各不相同，其实理解不同无所谓，现在都是一体化的建设思路，因此现在最好都用BOSS国际上对于描述电信的支撑系统到底应该称之为BSS，还是OSS，或者称之为BSS/OSS 都是一个没有定论的东西。

比如TMF推出的NGOSS概念，就是代表电信的支撑系统，包括我们所说的BSS和OSS；但是他就叫OSS，只是前面加了个前缀NG。
