Summary
The 5G system is designed to offer optimal resources, security, capacity, and quality for a variety of use cases. The most essential new core network concepts in 5G are thus the separation of user plane and control plane, network slicing, and service-based architecture (SBA). To comply with strict performance requirements for the 5G networks, the optimal deployment can be done by relying on increased intelligence, flexibility, and automation in the transport network. The 5G core network is based on cloud concept, and the most efficient forms of the core will take advance of network slicing and SBA. The 5G protocol layer consists of the variants present in each reference point of the new architecture. There are many services defined in previous 3GPP releases, which keep evolving and are valid also in 5G era, in a parallel fashion.
