Trend and Progress
In the next-generation network, the business mode of operators will be changed from only providing network
support to dominantly controlling the network, and operators will have self-planning and self-design
capabilities.
SDN and NFV actually turn software into a crucial element of network establishment and networking
technologies. The skills and strength related to software and software systems will become the real hard
power of operators.
In this background, operators are changing at an astonishing speed and magnitude. Most of the mainstream
operators in the world have started cloud transformation.

Major standards organizations also put their focuses on the design of telecom O&M standards and
models. Operators and equipment manufacturers actively participate in the research and play
increasingly important roles, greatly improving the maturity of standards.
With the number of members of open-source communities increasing rapidly, the iterative process of
open source versions is accelerating and a variety of O&M-based open source technologies are emerging.
Organization Features
The NSO&RO in the NFV domain involves the resource layer and service

manufacturers are highly involved. For NFV and SDN end-to-end

In conclusion, the next-generation operation system of operators is no longer a simple back-end O&M
system or a simple Service Online system, but a customer-facing frontend service system and value
creation system that can achieve DIY "Service-On-Demand". It is a customer-facing product and solution
development platform, operation platform, and eco-chain building platform that integrates operators'
network resources, IT resources, user resources, third-party contents and applications, and will gradually
become an operating system for operators to carry out operation.
Facing all these challenges, the next-generation Operation Support System (OSS) should be virtualized,
automated, simplified, optimizable and intelligent.

for Resource and Network
GI
The Global Information (GI) module is responsible for centralized resource
information management for operators. It interacts with the resource management
modules and databases on cloud platforms and the network to obtain related
information, presents operators with a real-time resource and topological view of
the SDN/NFV on the global scope, and provides APIs for other modules to obtain
global resource information. Its main functions are as follows:
◆ Provides cross-network, cross-domain, and cross-manufacturer resource
management and topology management, including physical resources, virtual
resources, and service resources.
◆ Visualizes service modules and topology relationships, and supports data
collection from third-party networks.
◆ Provides global resource analysis and a resource dashboard.

By exposing capabilities, operators can attract partners, develop innovative applications, and attract
final consumers with abundant new applications. In addition, operators can form positive feedback by
increasing the number of partners and consumers, continuously dig out potential service value, expand
the industry chain, and finally form an open and win-win ecological chain.

NE. MANO, which is responsible for managing virtualized devices, can be
deployed independently, has very few interfaces with the existing network,
and thus can get online rapidly. However, this mode has the problem
that the advantages of the new network cannot be fully utilized, and its
O&M mode is similar to the traditional mode. In phase I, the orchestration
system is introduced to implement the orchestration of resources,

management and on-demand network slicing service.
Phase II: With gradual deepening of transformation, the old and new networks are managed in a coordinated
way by domains. A self-service portal and orchestration system are added to manage the SDN/NFV network.
The traditional network is managed by the existing BSS/OSS system, which is slightly reconstructed to meet
