China's four major operators participated in the world's first 5G inter-network roaming trial commercial launch ceremony

News on May 17, today’s date in China is May 17, 2023. The world's first 5G different network roaming trial commercial use was officially launched this morning at the opening ceremony of the 2023 World Telecommunications and Information Society Day Conference. In this important launching ceremony, the four major operators China Mobile, China Unicom, China Telecom and China Radio and Television all participated.

According to ITBEAR Technology Information, the World Telecommunications and Information Society Day Conference is a fixed commemorative event that the International Telecommunication Union requires member states to carry out on May 17 every year since 1969. It is also the top international event in the field of information and communications. . This year’s ITU theme is “Information and Communication Technologies for Enhancing Capacities of Least Developed Countries”. Combined with the development of my country's information and communication industry, the Chinese theme is "Welcoming the new era, starting a new journey, and taking on new missions."

##In the opening ceremony, China Telecom, China Mobile, China Unicom, China Radio and Television, China Tower, Huawei, Qualcomm, China Information Technology, Inspur and other companies actively participated.

5G remote roaming means using a SIM card signed with a specific communication operator, which can also be used normally on the networks of other operators. Users can access other operators' 5G networks and use network services in areas not covered by their own operator's 5G network. This technology realizes this function. By doing so, the network becomes more open and shared, and resources are better reused, making the entire network more efficient.

According to the “14th Five-Year Plan” information and communications industry development plan, China will comprehensively promote the construction of 5G networks and further promote the co-construction and sharing of telecommunications infrastructure. The mobile communication network pattern will realize the coexistence of multiple networks in hotspot areas and the support of one network in remote areas by promoting 5G roaming across different networks. The "Plan" calls for accelerating 5G inter-network roaming test verification and equipment upgrades to ensure that all 5G networks in administrative regions at the county level and below have inter-network roaming capabilities. In addition, basic telecommunications companies are encouraged to carry out roaming on different networks under the market-oriented mechanism, and provinces/autonomous regions such as Tibet, Xinjiang, Inner Mongolia, Qinghai, Gansu, and Heilongjiang are supported to prioritize pilots for roaming on different networks.
