Through persistent determination and effort telecom operators are implementing a digital transformation to create a better digital world. To provide individuals and enterprises with an on demand, real time, DIY, all online, social experience requires an end to end (E2E) coordinated architecture featuring automatic, agile and intelligent operation during each phase. In the new exciting era of 5G, new communication requirements pose challenges on existing networks in terms of technologies and business models. The existing mobile network architecture was designed to meet requirements for voice and conventional MBB services. However, this previous organization has proven to be insufficiently flexible to support diversified 5G services due to multiple 3GPP version upgrades, a large number of NEs and complex interfaces. The service-driven 5G network architecture aims to flexibly and efficiently meet diversified mobile service requirements. With software-defined networking (SDN) and Network Functions Virtualization (NFV) supporting the underlying physical infrastructure, 5G comprehensively cloudifies access, transport, and core networks. Cloud adoption allows for better support for diversified 5G services, and enables the key technologies of E2E network slicing, on-demand deployment of service anchors, and component-based network functions.
CloudRAN consists of sites and mobile cloud engines. This facility coordinates multiple services, operating on different standards, in various site types for RAN real time resources that require a number of computing resources. Multi-connectivity is introduced to allow on-demand network deployment for RAN non-real time resources. Networks implement policy control using dynamic policy, semi-static user, and static network data stored in the unified database on the core network side. Component-based control planes and programmable user planes allow for network function orchestration to ensure that networks can select corresponding control-plane or user-plane functions according to different service requirements. The transport network consists of SDN controllers and underlying forwarding nodes. SDN controllers generate a series of specific data forwarding paths based on network topology and service requirements. The enabling plane abstracts and analyzes network capabilities to implement network optimization or open network capabilities in the form of API. The top layer of the network architecture implements E2E automatic slicing and network resource management.
All that you hear about self-driving cars and self-driving trucks, autonomous drones, the Internet of Things, Virtual Reality and Augmented Reality; they all need a fast, reliable, high-capacity wireless network. That’s the promise and the potential of 5G. In this course, by LogicFinder, we’ll take a look at what 5G is, how we got here, its architecture in detail and what it means to you as a consumer, a business owner or entrepreneur, a property owner or building manager, and as a citizen.
