The "Plan" includes four parts, namely, the development basis and the situation, the overall idea and development goals, the development focus, and the safeguard measures. The "Plan" pointed out that the 5G network construction will be fully promoted. Deeply promote the co-construction and sharing of telecommunications infrastructure, support the co-construction and sharing of 5G access networks, promote 5G inter-network roaming, and gradually form a mobile communication network pattern with multiple networks coexisting in hotspots and remote areas with one network underpinning. At the same time, speed up the withdrawal of 2G and 3G networks, and coordinate the coordinated development of 4G and 5G networks. The "Plan" requires that 5G inter-network roaming testing and verification and equipment upgrades be accelerated, so that all 5G networks in administrative areas at the county level and below have inter-network roaming capabilities, encourage basic telecommunications companies to carry out inter-network roaming under a market-based mechanism, and support Tibet, Provinces such as Xinjiang, Inner Mongolia, Qinghai, Gansu, Heilongjiang, etc. give priority to launching trials of roaming across networks. In accordance with the relevant requirements of the "Ministry of Industry and Information Technology's Implementation Opinions on Promoting Open and Sharing of Networks and Promoting 5G Inter-network Roaming" (Information Administration of the Ministry of Industry and Information Technology [2020] No. 117), the promotion plan for 5G inter-network roaming is: to promote the implementation of 5G inter-network in 2021 Technical research on roaming solutions, forming relevant technical standards, formulating relevant test standards, completing 5G inter-network roaming laboratory tests, and organizing pilot work on existing networks. Before the end of 2022, 5G networks covering urban and rural areas, advanced technology, high quality, intensive, efficient, safe and reliable will be basically completed, and 5G inter-network roaming will be fully promoted. All enterprises should have 5G networks built in administrative regions (including counties) below the county level. The function of roaming between different networks makes the best use of the established 5G network to provide services for a wider group of users. According to technical experts from China Unicom, 5G inter-network roaming can maximize the openness and sharing of networks, strengthen resource reuse, and enhance the overall development efficiency of 5G networks. 5G inter-network roaming includes two technical routes: core network roaming and access network sharing. In roaming areas, roaming operators provide voice, data, and short message services to local network users and roaming users of other operators to ensure the same communication quality . However, it needs to be pointed out that there are still many technical and cooperation mechanism challenges in current 5G inter-network roaming, and it is necessary to accelerate technical research, equipment development, and test verification. It is recommended that the regulatory authorities take the lead in determining the technical route and interconnection plan, and formulating a unified inter-network roaming settlement price.
