From "1+1" on March 1, to "41+128" on March 13 and "9+130" on March 14, Shanghai is experiencing complex and severe epidemic challenges.
In recent days, communities in Shanghai have successively implemented closed management and carried out nucleic acid testing for residents in the community. In designated hospitals and centralized isolation areas, nucleic acid testing is also being carried out intensively. In Shanghai Telecom, there is a network optimization team that ensures the smooth flow of thousands of nucleic acid testing points in the city at all times.
The reporter took 48 hours as a "slice" to record the anti-epidemic figure of this group of Shanghai Telecom Network excellent people at the nucleic acid testing point. These 48 hours were not deliberately chosen, but were only a few randomly selected from the time of the Shanghai Telecom people's war epidemic. During these 48 hours, front-line network optimizers responded to demand on the spot, racing against time to optimize the network, and back-end support personnel echoed each other anytime and anywhere. In their work group, during those 48 hours, only 1 a.m. to 3 a.m. no one spoke.
Provide network guarantee for the verification and inspection of sealed and controlled communities
When: March 11, 19:58
Location: A residential area of Haifeng Road, Jinshan District
On the evening of March 11, a community on Haifeng Road in Jinshan District implemented closed management and carried out nucleic acid testing for all employees. Because a large number of users accumulate in a small area in a short period of time, the network load is greatly increased, and the mobile phone signal is poor, which affects the smooth development of nucleic acid testing.
At 19:58, after learning of this situation, Shanghai Telecom responded quickly. The community is a super-large community with nearly 50 buildings, and because it is in a closed management state, Yang Ming, director of the Southern Operation Center of Shanghai Telecom Mobile Internet Department, and technicians cannot enter the scene to understand the specific situation.
In view of such a situation, on the one hand, the personnel of Shanghai Telecom's Mobile Internet Department communicate with multiple parties to understand the specific location of the nucleic acid testing point in the community and other information. On the other hand, Sun Zhiqiang, director of the Mobile Network Data Operation Support Center, and technicians combined with the scene situation, through the analysis of background data, formulated a corresponding solution, and adjusted the antenna angle of the nearby base station through remote control to thicken the coverage of the key area of the community. In this process, the technicians have been in contact with the residents of the community to ensure that the optimization measures have effectively improved the quality of the user's access to the Internet and the nucleic acid work.
At 21:04, there was no problem with the signal coverage of the cell.
In the top three hospitals "pick the lights at night"
When: 21:16, March 11
Location: Ruijin Hospital
Recently, the amount of nucleic acid testing in Shanghai has increased significantly, and in Ruijin Hospital, there is often a "long queue" in front of the nucleic acid test window, which also increases the pressure on the network.
At about 9:00 p.m. on March 11, after receiving the task, Shanghai Telecom technicians rushed to the scene of Ruijin Hospital and took various measures to optimize and improve the network quality here, so as to facilitate the hospital to better carry out anti-epidemic work such as nucleic acid testing.
One of the measures is to adjust the antenna angle of multiple base stations near the hospital to strengthen signal coverage. One of the base stations encountered difficulties in adjusting, "This base station is located on the roof of a building, built relatively early, can not be through remote control of the base station antenna down operation, can only be manually operated." Lin Yu, director of the Northern Operation Center of Shanghai Telecom's Mobile Internet Department, who participated in the on-site support, said. After communicating with the property, the technicians who do a good job of self-protection are allowed to enter, and the base station antenna will be adjusted accordingly after climbing to the roof.
At the same time, the technical staff of the Southern District Bureau of Shanghai Telecom have further improved the quality of the mobile communication network here through various methods such as the introduction of the room and the addition of micro base stations in the corridor outside the hospital outpatient building. "The extra-external introduction of the room is to lead part of the antenna to the outdoor in the case of surplus room capacity, and enhance the coverage of the outdoor local area, mainly for nucleic acid detection points." Lin Yu introduced it to the reporter of Shanghai Telecom Daily.
In this process, the background of the whole process of cooperation, in the early morning, the newly added micro base station was successfully opened, providing strong support for the hospital to smoothly carry out nucleic acid testing.
Emergency vehicles appear wherever they are needed
When: 23:00 on March 11
Location: A residential area of Shangmao Road, Qingpu District
At 23:00 on March 11, after receiving the task, the Shanghai Telecom Emergency Communications Bureau urgently dispatched a C-network emergency base station car and drove to a community located on Shangmao Road in Qingpu District in the night.
The community is a sealed community, and centralized nucleic acid testing should be carried out for residents of the community. This C-network emergency base station car arrived here to provide network support for the smooth development of nucleic acid testing. Under the tense busyness of the technical personnel, at 4 a.m. the next day, the emergency base station was opened.
Since the outbreak of this wave of the epidemic, emergency communication vehicles have appeared rapidly wherever they are needed, and four batches of emergency communication vehicles have been set off continuously for up to 1 day.
Solve the problem of slow PDA scanning code for medical staff
When: 9:07 a.m. on March 12
Location: Songjiang Residential Area
Many residential communities in Songjiang carry out nucleic acid testing work, but the handheld PDA terminal used by medical staff is very slow in the process of scanning the two-dimensional code of residents, which greatly affects the efficiency of nucleic acid testing.
Epidemic prevention work is a race against the virus and time. After learning the situation, Shanghai Telecom once again took a quick action, with Sun Kai, director of the Western Operation Center of the Mobile Internet Department of Shanghai Telecom, and Qin Chao, deputy director of the Mobile Network Operation and Management Department, and others participating.
"We have taken a variety of measures, one is background analysis, using multiple base stations to share the traffic volume, and the other is to link up with other departments to increase the priority of the detection card used by PDA terminals, that is, compared with ordinary services, priority access to the network can be given." Qin Chao said. At the same time, a team of more than a dozen people rushed to the scene for optimization, and because they could not enter the scene of the sealing and control community and the sealing and control park, they guided the corresponding personnel to conduct auxiliary tests, so as to complete the on-site speed measurement and debugging work.
Send millions of epidemic protection TEXT messages in 3 hours
When: 4:00 a.m. on March 13
Location: Shanghai Telecom Mobile Internet Department office
During this time, the amount of nucleic acid testing has increased significantly, and the number of queries about nucleic acid results on the corresponding platform has also soared.
In order to maintain the smooth operation of the platform and allow the public to smoothly inquire about the nucleic acid test results, at 4 a.m. on March 13, the WeChat group of the Shanghai Telecom Security Team was once again "lively". Jin Chang, director of the Mobile Core Network Maintenance Center of the Mobile Internet Department, deployed the task, and the quality assurance center and other departments immediately took action quickly to organize forces to monitor the load capacity of the SMS network element and the carrying capacity of the wireless network in real time, and be ready to respond at any time.
In the end, the task took about 3 hours to complete smoothly, and millions of text messages were sent, reminding those citizens who had completed nucleic acid testing to log in to the corresponding query platform.
At 9:00 a.m. on this day, Shanghai Telecom received another request to send a nucleic acid detection prompt text message to Fengpu Street, and the relevant team immediately organized forces to implement the text message sending and monitor the text message transmission in real time.
"Escort" for key apps such as the application
Time: 12:00, March 13
Location: Wusheng Building
When this wave of epidemic came, the mobile Internet Department of Shanghai Telecom quickly set up an epidemic prevention and security team, with the participation of expert backbones and department heads, playing the role of "mobile network brain" and actively participating in the fight against the epidemic.
In order to further strengthen the network guarantee for nucleic acid detection, the expert team, led by Shanghai craftsman and mobile network optimization expert Chen Xiaofang, completed the optimization of the Youweijian system in 24 hours, clicked on the corresponding area on the map, you can query and display the base station near a nucleic acid detection point and its capacity, load and other indicators, and provide efficient support for nucleic acid detection work through visualization tools.
The team of experts also regularly samples data from all inspection points and reports on network quality every hour during emergency support. At 12:00 on March 13, after receiving the task of health cloud and business quality monitoring with the application app, the expert team communicated data across departments, obtained the business quality monitoring data of these key apps, and added to the hourly report to timely monitor and respond to the use of key apps.
