China Telecom and China Unicom promotes 5G co-construction and sharing

Xining, Guangzhou, Taiyuan, Dalian, Nanning, Quanzhou, Xiamen, Shenyang… In the last month, China Telecom and China Unicom have partnered to open the first 5G shared base station in several cities in China. All this began on September 9 this year, when the two operators announced that the 5G network had been built to share. This set the first step for domestic operators to build a network of deep, large-scale cooperation.

Judging from the rapid increase in the number of cities opening the first 5G co-construction and shared base stations, the two sides are moving very quickly. According to the IT Times reporter understand that before the end of November this year, the two operators before the construction of their own 5G base stations should have shared capacity, specifically, carrying network sconnect, wireless network with the opening of sharing conditions.

Of course, the two sides still have some difficulties to overcome in the 5G co-construction and sharing, both technical and internal communication and coordination, which need to be further improved and opened up.

Share 5G base stations in 8 cities

According to public information, China Telecom and China Unicom have jointly opened the first local 5G shared base station in eight cities in China.

On September 25, Qinghai Telecom and Qinghai Unicom opened the first 5G co-construction and sharing station in Xining City, based on a set of physical equipment to open a separate carrier of 100M and 100M, with an average rate of more than 1Gbps and a peak rate of more than 1.5Gbps.

On the evening of September 27th, Guangdong Telecom and Guangdong Unicom opened the existing network, opened a 5G current network commercial sharing site in Guangzhou, and successfully accessed telecommunications and Unicom 5G users. After field testing, the user rate on both sides is close to 1000Mbps.

Then, on the same day on September 28, Shanxi Unicom and Shanxi Telecom successfully opened the province’s first shared 5G base station at Taiyuan City Sports Center, and Liaoning Unicom and Liaoning Telecom opened the first 5G shared base station in Northeast China in Dalian.

On October 10, Fujian Telecom and Fujian Unicom opened a 5G shared base station in Xiamen, and on the same day, Guangxi Unicom and Guangxi Telecom opened the first 5G shared test station in South China City, Nanning Jiangnan District. On October 11th, Fujian Telecom and Fujian Unicom opened 5G shared base stations in Quanzhou.

On October 15, Liaoning Telecom and Liaoning Unicom successfully opened Shenyang’s first 5G shared base station.

Zoning construction cities still to be broken

According to the “5G Network Co-construction and Sharing Framework Cooperation Agreement” signed by China Unicom on September 9th, the two sides will be built in 15 cities: 5 cities in Beijing, Tianjin, Zhengzhou, Qingdao and Shijiazhuang, with China Telecom and China Unicom building a regional ratio of 4:6; Shenzhen, Hangzhou, Nanjing, Suzhou, Changsha, Wuhan, Chengdu, 10 cities, China Telecom and China Unicom construction area ratio of 6:4. In addition to the above areas, China Telecom independently built 10 cities in Guangdong Province, 5 cities in Zhejiang Province and 17 provinces, and China Unicom independently built 9 cities in Guangdong Province, 5 cities in Zhejiang Province and 8 provinces.

Comparing public information with the contents of China Unicom’s September 9 announcement, it is not difficult to find that in 15 cities, such as Guangshen in the north, only Guangzhou has opened the first 5G shared base station.

“We’re still going through the testing process, and it’s a lot of hard work, like data configuration problems on both sides, and it takes a lot of effort.” A local operator involved in the 5G co-construction and sharing of people told reporters that his city is in the telecommunications Unicom two sub-districts of the construction of 15 cities. According to this person, this week they will report to the group 5G base station co-construction and sharing joint working group members list, next week will be reported to the co-construction of shared technology program.

Installed base stations have shared capacity at the end of November

At the recent China Unicom Smart Eco-Cooperation Conference, Wang Xiaochu, chairman of China Unicom, said that according to China Unicom’s 50,000-g base station construction plan at the end of this year, most of the base stations are now completed, of which 28,000 base stations have been opened.

As for the progress of building and sharing 5G with China Telecom, Wang Xiaochu said that procedures and equipment have been opened in the corresponding cities. But he did not disclose a specific schedule of tasks.

According to the “IT Times” reporter understand that the two operators have made the corresponding time schedule: for the installed 5G base station, the requirements of the existing base station sharing program, November 30 with sharing capacity, that is, carrying network interoperability, wireless network has the conditions to open sharing; Stop the construction of 5G base stations in non-construction areas, no construction sites will be adjusted to their respective construction areas in 2019, and in principle, construction work will be completed by November 30, with 100% sharing functions open.

“The requirements for both sides should be the same, that is, the 5G base stations already under construction by November 30th will have the conditions to share, ” said the local operator insider.

Focus on the overall situation to promote co-construction and sharing

At present, the two sides to deeply promote 5G co-construction and sharing, there are still difficulties to overcome.

China Telecom’s 5G band is at 3400MHz-3500MHz, a total of 100M bandwidth, China Unicom is 3500MHz-3600MHz, is also 100M bandwidth resources, the two operators 5G band adjacent, can be used to share spectrum resources, the bandwidth will be doubled, into 200M, This allows users to get faster internet speeds and better experiences. But this requires the support of the industrial chain, and some network equipment needs to be redesigned to support doubling the frequency range, as well as in terms of terminals, requiring further design and development.

Moreover, the two sides are currently co-building and sharing on NSA 5G, and certainly support SA for the future. That is to say, the future 5G base station is dual mode, a base station needs to connect telecommunications and Unicom’s 4G, 5G core network, a total of 4 core network connections, which need to further solve the technical problems.

In terms of management, communication and coordination between the two operators is particularly important in the process of 5G co-construction and sharing. Wang Zhiqin, vice president of the Xintong Institute, said in an interview with the media that after the sharing, a 5G network used by two operators, but only one operator in one region can manage, and the other can observe but not implement the adjustment of base station parameters. Therefore, the two operators should establish rules, through the constraints of the agreement to optimize the mechanism of coordination and communication, to ensure that a network can meet the quality needs of the two enterprises.

Although there are some difficulties, but from the overall situation and the long-term perspective, the two operators to carry out 5G network co-construction and sharing, help to reduce 5G construction and operation costs, efficient realization of 5G network coverage, the rapid formation of 5G service capacity, which is beneficial to both sides, good for the industry, good for users.
