Network slicing an operators’ way to how to build and manage a 5G network.
FREMONT, CA: Network Slicing has taken the 5G world by storm and rightfully so, it consists of a functionality that enables multiple independent networks to exist on the same physical mesh network. 5G enables new business model innovation across all industries. Network slicing is poised to play a crucial role in enabling service providers to offer innovative services, enter new markets, and expand their business.
What is Network Slicing?
Network slicing is the operator's way to build and manage a network that meets and exceeds the emerging requirements from a wide range of users. The way to achieve a sliced network is to transform it into a set of logical networks on top of a shared infrastructure. Each logical network is designed to serve a defined business purpose and comprises all the required network resources, configured and connected end-to-end. Network slice has low latency, high bandwidth, and ultra-reliability, which are critical for IoT use cases.
To efficiently manage the network slices and to maximise revenues, a modern OSS and BSS providing automated business and operational processes is necessary. With programmable and flexible 5G networks and advanced AI andSLA-driven orchestration, the required network functions can be flexibly created, quickly deployed, and automatically managed throughout its lifecycle.
Benefits of Network Slicing
End-to-end network slicing enables new business model innovation and use cases across all verticals, and creates new revenue opportunities for communication service providers. It also provides service flexibility and ability to deliver services faster with high security, isolation, and applicable characteristics to meet the contracted SLA. Network Slicing allows customers to maximise the return on investment via efficient usage and management of the network resources and provide differentiated services at scale.
A slice may consist of dedicated radio, transport, and core resources including a dedicated user plane function at the edge. Another slice shares radio & transport resources between tenants but provides dedicated core network functions per tenant. A concert promoter may want to take a short-term lease of a network slice for a week-long musical festival and optimise that slice for streaming HD music and VoIP connectivity. Alternatively, an electrical utility may want to take a long-term lease of a network slice for connectivity of its smart grid composed of sensors, metres, and controllers and optimise that slice for IoT devices.
