ata. It will also enable an open ecosystem for data exposure and analytics. Another major difference compared to EPC is that multi-access support is built in right from the beginning, enabling efficient use of different fixed and mobile network assets to provide access-independent value-added services, maximized data rates, increased reliability, and improved user experience. These new capabilities will further enable building of end-to-end network slicing, enabling public and private operators to address the needs of various verticals by dynam- ically adapting the network to their specific requirements. Network slices can be isolated from each other in terms of connectivity and resource allocation, creating "virtual pri- vate service networks." These can be configured in specific ways to achieve, for example, low latency, or high reliability, or both, and new network slices can be introduced easily via automation, thus enabling new business models that were not feasible with dedicated physical networks. The resulting 5G Core Network Architecture (simplified) is depicted in Figure 5.4. The point-to-point architecture that has been used up to 4G still applies to some inter- faces in 5G. In the point-to-point model, different network functions are connected over standardized interfaces that allow for multivendor networks. This is well understood both conceptually and operationally; it has served mobile operators for decades.

Now, however, that with the transition to a cloud infrastructure and the need for greater service agility, the point-to-point model is no longer the best option for all
