Research on the evolution of 5G NSA radio access network sharing

Abstract： There are more and more mobile operators had launched 5G services in 2019, 5G is entering a critical period of commercial deployment globally. Considering the maturity of SA standards, equipment and terminals, 5G shared network is based on the NSA architecture in the initial stage of 5G deployment, so the operators need to consider evolution towards SA phase in order to ensure that the network sharing would last throughout the 5G life cycle. This paper systematically analyzes different evolutions from network complexity, operation and maintenance optimization complexity, user experience and so on, in order to provide an effective guideline for operators to choose the evolution for RAN sharing.
