China Telecom and China Unicom have reached a tentative agreement to jointly build a 5G network and share network infrastructure. And it's possible that China Mobile may join them.. China Telecom and China Unicom, two of China's three leading telecom operators, and two of its four 5G licensees, will jointly cover parts of the country with one shared 5G radio access network. In order to accelerate the large-scale deployment of 5G networks, China Telecom and China Unicom, in 2019, embarked on an innovative partner hip known as "5G co-construction and sharing". Essentially, 5G network co-construction and sharing means the. . Indirect Network Sharing is specified in 3GPP TS 22.261, TS 23.501 and TS 23.502, allowing the communication between the shared RAN and the core network of the participating operator to be routed through the core network of the sharing parties, as one of the key pragmatic measures of 5G Network. . China Tower is a world-leading tower provider that builds, maintains, and operates site support infrastructure such as telecommunication towers, high-speed rail, subway systems, and large indoor distributed systems. As of June 2019, China Tower boasted a combined 1.954 million sites. . The three Chinese operators co-own a tower company, China Tower Corp, so that would make it easier for them to.

China Telecom and China Unicom signed a strategic cooperation agreement to build a nationwide 5G access network, sharing 5G spectrum resources and bearer networks in 2019. At the end of December 2022, China Unicom had 1.17 million 5G base stations and China Telecom had a total of 1 million 5G base stations (Z. Wen, 2022b).
How does China Telecom & China Unicom co-build and co-sharing policy work?
By adjusting resource allocation, the government aims to balance the competitiveness of the MNOs and regulate the competitive landscape. The government's co-building and co-sharing policy brings China Telecom and China Unicom together to share resources and compete with China Mobile.
Why is sharing of telecom infrastructure a requirement in telecommunication industry?
Due to economy of scale property of telecommunication industry, sharing of telecom infrastructure among telecom service providers is becoming the requirement and process of business in the telecom industry where competitors are becoming partners in order to lower their increasing investments.
