5G Network Architecture. Core, RAN, & Security Architecture For 5G
Service-oriented 5G network architecture does away with limitations related to complex infrastructure and base station proximity. It allows functions to be flexibly combined depending on service requirements.†
The telecom sector is undergoing digital transformation to provide both individuals and enterprises with an on-demand, online, real-time, social experience that goes beyond the ordinary. However, this job is easier said than done and requires a coordinated architecture that features automatic, intelligent, and agile operation in every phase. It can be achieved by implementing 5G network architecture that features a comprehensive adaptation of operating systems, networks, and different network support services. The 5G network architecture is an all-cloud strategy that serves a dual purpose – It supports different application scenarios by rendering DC-based architecture and at the same time fulfils several service requirements by providing independent network slicing on a single interface. Let us now delve a little deeper into the concept of 5G network architecture and learn more about 5G Core architecture, RAN architecture, and its security features.
5G Core Architecture
If you were thinking where does 5G network architecture gets its improved throughput from, your answer lies here – 5G Core. It is the basis of the new specification associated with 5G. According to 3GPP, 5G Core architecture works on service-based architecture that runs across the 5G network architecture, including all its interactions and functions – session management, authentication, end device traffic, and security to name a few. It emphasises Network Function Virtualization (NFV) as a design concept that is integral to the entire architecture. It also simplifies the deployment of virtualised software functions with the help of Multi-Access Edge Computing (MEC), an essential element of 5G network architecture.
Radio Access Network (RAN) utilises NFV and its features through O-RAN and other similar alliances that emphasise network dis-aggregation. The flexibility associated with 5G network architecture has got a lot to do with this extension of NFV to RAN. It is also responsible for the scalable arrangement of new technology and features by providing open-source development, providing competition with new opportunities, and more. O-RAN promotes faster and easier inter-operability by allowing multi-vendor deployment. It also provides a means to track and enhance the user experience by enabling network elements to be virtualised. The virtualisation of RAN elements brings more cost-effectiveness in terms of software and hardware utilisation. It comes in handy, especially in situations in which the number of devices in question is enormous – For instance, in IoT applications.
5G network architecture is open to several security risks. However, efforts are underway to bring in more security features to build more trust with individuals and enterprises that are apprehensive only because of the security risks associated with 5G. There are still many improved security features that 5G currently has, including flexible security policies, unified authentication, Permanent Subscriber Identifiers (SUPI), and extensible authentication amongst others. These features ensure secure transactions, privacy, and bring layers of authentication to protect users from network-related security issues.
