On November 5, the first China International Import Expo, which has attracted worldwide attention, will unveil its mystery. Holding the China International Import Expo is a major decision made by the Party Central Committee with Comrade Xi Jinping at its core, and it is a major political task that Shanghai must complete. As the vanguard of Shanghai's communication services and the main force in the construction of a smart city, Shanghai Mobile started the communication guarantee work for the CIIE as early as the beginning of the year. At present, Shanghai Mobile is fully prepared and ready to go, and will experience China Mobile's top-level communication network quality and first-class comprehensive service level with guests, exhibitors and visitors from all over the world, and show the world the strength and confidence of China's communication enterprises.
Ensure that 500,000 people in the museum can access the Internet at the same time
At the beginning of this year, China Mobile set up a special support team for network engineering lines through "national linkage and full participation". Over 10,000 people in the whole group participated in the remote communication support work. During the exhibition, hundreds of experts were stationed in Shanghai. Fully support the communication guarantee work of the first CIIE. This guarantee has many difficulties, such as "the single-day passenger flow is historically high, and the reconstruction of the venue is the most difficult". China Mobile's expert team has finally solved the problem of communication interference under high-density deployment of stations through several program discussions. By stacking all mobile frequency band resources in the venue, the heterogeneous networking method of "inter-frequency and multi-standard" is adopted. In the limited space of the venue, the shaped antenna is cleverly used, the antenna design angle is flexibly customized according to the field test data, and the 30-degree narrow beam is used to precisely control the coverage of each cell, so as to suppress the interference in the network and improve the wireless communication capability of the exhibition hall. 6.5 times.
At present, the National Convention and Exhibition Center can satisfy up to 500,000 people using mobile phones to surf the Internet at the same time, and the Internet speed can reach 60 megabits per second under the stress test. In the sprint stage of CIIE security, Shanghai Mobile continued to carry out the 24-hour uninterrupted security work of "Four Leaf Clover", organized more than 300 emergency drills at all levels, and ensured that the communication security of the CIIE was "safe" with the most comprehensive preparations.
In addition to the "domestic leading, international first-class" networking method, Shanghai Mobile has also used the "breathing network" for the first time to ensure on-site mobile communication. By intelligently adjusting according to the real-time flow of people and usage in the venue, it is compatible with the tidal flow of people in the exhibition. The features are compatible and meet the needs of flow regulation and signal increase under large passenger flow. When the passenger flow is not very large, the wireless communication network in the exhibition hall will show its high-quality advantages, and users can enjoy an extremely fast download experience, with a peak rate of 170 megabits per second. When the number of mobile phone users in the museum exceeds the preset limit, the capacity of the network will be further improved to ensure that customers can use business normally under the impact of large passenger flow.
On the North Square of the National Exhibition and Convention Center, the emergency communication command vehicle of Shanghai Mobile has long been in place, and a large-capacity antenna called "the strongest antenna" in China is installed on the roof of the vehicle. This antenna is an independent antenna in my country. Innovative and self-developed, it can triple the wireless communication capacity in the region.
At the CIIE, Shanghai Mobile will also conduct a 5G pilot test to create a smart pavilion under the 5G network environment for the CIIE. At present, Shanghai Mobile has built 21 5G base stations in the national exhibition area, taking the lead in completing the continuous scale 5G coverage of the national exhibition center, and introducing the world's first integrated 5G small base station in the main exhibition hall for the first time. On the on-site 5G exhibition car, Shanghai Mobile will demonstrate the application of China's 5G technology in all walks of life to guests from all over the world.
Ensuring a high-quality international business experience for guests
During the CIIE, the National Exhibition and Convention Center will welcome large-scale international customers to ensure a good communication experience for guests from all over the world, which is also one of the important tasks of Shanghai Mobile. Over the past six months, Shanghai Mobile has organized a large number of "carpet" international service tests for operators around the world. Shanghai Mobile actively connected with more than 300 operators in 165 countries, obtained sim cards of foreign operators, tested the usage perception of calls, Internet access and text messages, and tracked signaling. At present, the Shanghai Mobile communication support team has basically completed the testing of more than 2,000 Guoman card test cards for all operators, and found and rectified more than 100 problems. At the same time, Shanghai Mobile also conducts interoperability tests on relevant websites for overseas visitors to browse their own government websites, trade websites, corporate official websites and other international Internet usage needs, so as to ensure the quality of overseas visitors to visit their own websites.
At present, Shanghai Mobile has opened service counters and English-only seats for the CIIE. On November 2, 6 languages, including English, Japanese, Korean, German, French and Spanish, were officially launched, which will better serve exhibitors and guests from all over the country.
At the beginning of September this year, the National Exhibition and Convention Center, China Mobile Shanghai Company and Donghao Lansheng Group jointly signed a strategic cooperation agreement to cooperate closely in communication guarantee, information services, smart venues, etc., and comprehensively improve the operation management level and service level of the National Exhibition Center. During the CIIE, Shanghai Mobile specially customized 30 information stations to provide information services such as inquiries around the exhibition hall and related information of the CIIE, intelligent charging, self-service translation and other information services, so that the audience can experience a "smart exhibition". "Charm.
At that time, the smart venue integrated management platform and large display screen customized by Shanghai Mobile for the National Exhibition and Convention Center will also be unveiled for the first time. Through the application of the latest technologies such as the Internet of Things, big data and artificial intelligence, it will provide information services for the management of the exhibition hall. The transformation of various intelligent IoT applications, including remote monitoring of street lamps and temperature and humidity collection in core computer rooms, will help the exhibition hall to further reduce the cost of venue management.
