5g networks: the evolution to an open network architecture. Part 1. Key elements of open 5g network infrastructure solutions concept

When deploying 5G mobile networks on top of existing or newly built network infrastructure, operators and telecommunications service providers are interested in adopting open solutions, allowing the use of hardware platforms and software from different vendors in the same network. This interest is also being stimulated by introduction of new, cloud-based technologies on 5G networks with extensive use of data centers. This series of publications defines the basic elements (part 1) and provides an overview of the standardization work (part 2) of open solutions and interfaces for 5G network infrastructure.
