中国的电信行业面临着分拆和重组,由于竞争格局的逐步形成,电信行业的信息化建设更是倍受各电信服务提供商的关注。电信信息化目前最火的要算“BSS/OSS”系统了,但是电信信息化系统应该如何划分还真让人一时说不清楚。通过一张图可以让我们对电信信息系统了解得更透彻。电信信息系统可以分为以下四个层次:最底层:运营维护系统,包括了网管传输、智能网系统、本地网管、PDH/SDH 等与硬件平台打交道的系统;第二层:业务支撑系统,就是 OSS系统,这一层包括了“九七工程”、计费/帐务系统等业务系统;第三层:管理信息系统,包括 OA系统、财务系统等:最上层:决策支持系统,包括数据
China’s telecom industry is facing the spin-off and reorganization. Due to the gradual formation of the competitive landscape, the telecom industry’s information construction has drawn much attention from telecom service providers. At present, the telecom informationization is considered as the “BSS / OSS” system. However, how to divide the telecom informationization system really makes it unclear for a while. Through a picture allows us to understand the telecommunications information system more thoroughly. Telecommunication information system can be divided into the following four levels: The bottom layer: Operation and maintenance system, including the network management transmission, intelligent network system, local network management, PDH / SDH and hardware platform to deal with the system; The second layer: business support system is OSS system, this layer includes the “97 Project”, billing / billing systems and other business systems; The third layer: management information systems, including OA systems, financial systems: Top: Decision support systems, including data
