What is 5GC?

5GC (5G Core) is the evolved core network architecture of 5G, designed to be more flexible, scalable, and efficient than its predecessors. It uses a service-based architecture (SBA) allowing network functions to interact with each other through well-defined interfaces. 5GC supports network slicing, enabling operators to create multiple virtual networks tailored to different use cases with specific requirements. It also enhances mobile broadband, supports massive machine-type communications (mMTC), and enables ultra-reliable low-latency communications (URLLC), facilitating applications like autonomous vehicles, industrial automation, and advanced IoT deployments.
