Digital Transformation Services of the Mobile Core in 5G – Wipro

Versatile 5G Core architecture is key enabler to deliver wide range of use-cases

5G provides ultra-low latency, massive connectivity, enhanced mobile broadband services, higher capacity and power efficiency. 5G network slicing features make the network service-oriented by allowing different use cases with varying network requirements to run flexibly and simultaneously on the same physical network. 5G is more than just a network, it is a platform for innovation. In the overall 5G network system, 5G Core shapes the network services delivery, QoS implementation, policy enforcement, security, convergence of multiple access network systems and deployment of network slices.

5G Core system is expected to provide digital services to smart device users and as well to industrial systems and enterprises with wide range of connectivity requirements.

SDN concept enabled programmability of network and there by created new cloud service like network as a service (NaaS), 5G core system and the concept of network slicing facilitates creation of dynamic networks and elastically scale the network on demand. This will enable operators to efficiently deploy network resources and fine tune the network to customer requirements.

5G Core system is expected to highly distributed and to be hosted on edge cloud, regional or national DCs of service providers or on public clouds. Also, 5G core system to be offered in SaaS models for different enterprise and industry use-cases.

In order to meet these wide-range of requirements, 5G core system architecture shall be highly agile, modular, flexible, scalable, available, rapid, and efficient.

Cloud native architecture approach, separation of control and user plane (CUPS), service chaining and service-based architecture will address the requirements and change the way telecom core network is realized.

Architecture considerations to realize digital transformation of 5G Core

The 5G core architecture is defined as an SBA with clear separation of control and user plane functions. 5G core functions expose their services on a message bus that can be consumed by other functions. Following figure depicts 5G Core network functions as defined in 3GPP specifications.
