The 5G architecture will be cost-efficient to operate and have agile and flexible mechanisms in place for swift introduction of services. These properties are required to enable new business models.
A digital transformation is taking place in almost every industry. 5G will not only expand the broadband capability of mobile networks but will also help consumers and enterprises boost the efficiency of their lives and their business.
New business models using distributed cloud services and programmable networks will allow an unprecedented level of information sharing and enable collaboration among all kinds of industries.
The Ericsson 5G Systems white paper examines the main domains of a 5G system and how they must evolve to create a full-fledged 5G system. These domains comprise wireless access, transport, cloud, application and management (including orchestration and automation).
Using use cases reflecting diverse needs for latency and coverage it examines how a 5G deployment can support multiple business needs using network slicing and virtual network functions.
The use cases described are:
- Massive machine type communication (also known as Massive IoT): this requires ubiquitous connectivity for hundreds of thousands of low software and hardware complexity devices. This covers for example building automation, smart agriculture and fleet management.
- Critical IoT (cMTC or URLLC): this covers the requirement for low latency monitoring and control in real time. This covers situations such as control systems in a factory environment.
- Extreme mobile broadband: Servicing subscribers and businesses where high data-rate and low latency communications are needed. 5G promises to go far beyond 4G to provide more uniform connectivity and bandwidth over a wide area.
Using these examples, the white paper shows how the 5G system using flexibleradio access nodes, distributed and centralized data centers will allow network programmability for all types of services. The paper discusses the flexibility of the 5G system architecture regarding the access and core networks, and how software-configurable purpose built architecture will be needed to provide overall cost efficiency and help transform the business models of today into the distributed cloud-based future of tomorrow.
