To provide enterprises and individuals with a real time, on demand, all online, DIY, social (ROADS) experience requires an end- to-end (E2E) coordinated architecture featuring agile, automatic, and intelligent operation during each phase. The comprehensive cloud adaptation of networks, operation systems, and services is a prerequisite for this much anticipated digital transformation. The All Cloud strategy is an illuminated exploration into hardware resource pools, single network infrastructure to meet diversified service requirements and provides DC-based cloud architecture to support various application scenarios. to provide massive connections of multiple standards and implement on-demand deployment of RAN functions required by 5G. demand configuration of network functions through control and user plane separation, component-based functions, and unifed database management. maintenance, and termination for various services to reduce operating expenses through agile network O&M. distributed software architecture, and automatic deployment. Operators transform networks using a network architecture based on data center (DC) in which all functions and service applications are running on the cloud DC, referred to as a Cloud- Native architecture. In the 5G era, a single network infrastructure can meet diversified service requirements. A Cloud-Native E2E network architecture has the following attributes:Network Architecture-A High Level View 5G Network Architecture-A High Level View 5G 5G Will Enrich the Telecommunication Ecosystem In the new exciting era of 5G, new communication requirements pose challenges on existing networks in terms of technologies and business models. The next-generation mobile network must meet diversifed demands. The International Telecommunication Union (ITU) has classifed 5G mobile network services into three categories: Enhanced Mobile Broadband (eMBB), Ultra-reliable and Low-latency Communications (uRLLC), and Massive Machine Type Communications (mMTC). eMBB aims to meet the people's demand for an increasingly digital lifestyle, and focuses on services that have high requirements for bandwidth, such as high defnition (HD) videos, virtual reality (VR), and augmented reality (AR). uRLLC aims to meet expectations for the demanding digital industry and focuses on latency-sensitive services, such as assisted and automated driving, and remote management. mMTC aims to meet demands for a further developed digital society and focuses on services that include high requirements for connection density, such as smart city and smart agriculture. The expansion of service scope for mobile networks enriches the telecom network ecosystem. A number of traditional industries, such as automotive, healthcare, energy, and municipal systems participate in the construction of this ecosystem. 5G is the beginning of the promotion of digitalization from personal entertainment to society interconnection. Digitalization creates tremendous opportunities for the mobile communication industry but poses strict challenges towards mobile communication technologies. mMTC Massive Machine Type Communications uRLLC Ultra-reliable and Low-latency Communications Future IMT 10Gbps eMBB Enhanced Mobile Broadband 3DVideo, UHDScreen Work and play in the cloud Augmented reality Industry automation Mission critical applications Self driving car Smart Home/Building Smart City ITU-R WP5D 1million/km21ms 。。。以上简介无排版格式，详细内容请下载查看
