For stadiums, parks and squares, many such open spaces in Beijing have been specially planned for nucleic acid detection.
An Associated Press reporter in Beijing Mark Schiefelbein (Mark Schiefelbein) performed nucleic acid testing at a monitoring site in a park that was temporarily renovated from a museum site.
Like hundreds of thousands of people who were locked by big data and related to the location of Xinfadi, he hadn’t entered the market because he had taken pictures a few blocks away from the Xinfadi agricultural wholesale market in early June.The operator’s base station data was locked and received a telephone notification from the community neighborhood committee on a Wednesday afternoon, requesting to go to a nearby stadium as soon as possible for registration and accounting check.
Subsequently, he was transported to the park by a bus and queued up for testing.After finishing the work, he didn’t wait for the community to explain. He said: “I won’t go anywhere until there is no result.”
This foreign reporter is not only a China-connected person. After an epidemic, it even became a “Chinese national defense epidemic.”
Like him, the non-high-risk groups were notified of nucleic acid testing and hundreds of thousands of people who were locked in by the operator’s big data and associated with the new location.
Although many people are surprised, they also quite understand and cooperate with the need for investigation.
Armed inspection personnel under the scorching sun and a 24-hour continuous rotation inspection agency have become the backbone of the comprehensive prevention and control of this round of epidemic in Beijing.
Where does seamless information come from?
Including less than 10 days from June 11 to 20, including the aforementioned people locked in big data, Beijing’s expanding nucleic acid testing agency sampled 2.27 million people at an unprecedented rate.
During this period, a netizen posted a statistical chart of “2430 people visited Xinfadi Market and left Beijing, of which 91 people visited Shanghai”.It shows that big data not only knows who has visited/passed Xinfadi, but also knows where people who have visited Xinfadi eventually went.
In fact, this time many people are puzzled by the question of “just passing by car, why is it found me”, and the detailed location-specific personnel turnover statistics like the above, are behind the three major operators based on user mobile phones and communication base stationsData analysis and processing formed by the exchange of information between.
All the time the mobile phone has a signal, it is related to the ubiquitous base station in real time.For example, when many users use a mobile phone to make a taxi ride, positioning is not entirely dependent on satellites, but on the basis of recent base station data.The position of the base station itself is relatively fixed, and according to the relative position of the mobile phone and the base station, it can be sent to the mobile phone for accurate location records.
According to the technical explanation of the operator, the operator will not deliberately record the real-time location information of each user, but when the user turns on the navigation function, the nearest base station calculates the current location based on the real-time data.Based on the data exchange between the mobile phone and the base station at any time, it extracts the corresponding range of location data according to the key information, and sorts out which mobile phone numbers have stayed in this location.
Some netizens who did not understand the situation of this big data have also made rumors that Alipay and WeChat have helped the epidemic prevention department to lock in 350,000 people passing through the new destination by providing transaction data.
Of course, Alipay and WeChat broke the rumors at the first time: no relevant data were provided, and the epidemic-related information was mainly released by the health and epidemic prevention department.
The rumors stopped at the parties.
How to dig a gold mine for location services?
Regarding the new location, hundreds of thousands of people visiting and passing by were sorted out and sent reminder messages one by one. In fact, it was just an atypical case for operators in big data + location services for many years.
As early as in the 3G era ten years ago, operators had played the “abacus” of “location services”.At that time, the most optimistic about the user’s various needs for mobile phone positioning, such as location information query, route planning, peripheral search, navigation services, monitoring care, etc. At the same time, external marketing, assessment/attendance management, mobile resources from government and enterprise customersDemands for surveillance management, personnel safety monitoring, map navigation, etc. are also optimistic about operators, and they have developed location service promotion plans for major customers in logistics, justice, fishery, public security, insurance, tourism and other industries.
For example, after China Telecom acquired the CDMA network, it proposed the C network star chart business based on GPSone technology to users.
At that time, telecommunications technicians explained the advantages of GPS satellite + mobile network positioning to the media.”Positioning is more accurate, it can reach 5 meters. It can also be located indoors, and the combination of these two information sources can solve the problem that traditional GPS cannot solve, when GPS satellite signals and wireless network signals cannot be positioned separately.. And can achieve fast positioning in about 5 seconds.”
However, the paid location service for individual users faced huge challenges when the rise of third-party applications represented by Googlemap and Nokia’s free map.Operators are mainly facing enterprises, and secondly, personal location services have been hit by the free model.
In the 4G era, the increase in speed and fee reduction has caused rapid traffic growth. Operators have tried to gain more in location services. Even China Mobile has set up a location service base separately, highlighting the two capabilities of positioning and GIS maps.
In terms of positioning capabilities, it also specifically opens number-based positioning capabilities to industry location applications, including: area code positioning, CELL-ID positioning; opening positioning plug-in capabilities for individual developers, hoping to innovate various location applications based on location capabilities with various partners.At the same time, it also gave consumers a slogan of “4G era, providing full-process services from planned travel, on the road, and then to the destination, attractions overview, ticket inquiry, local specialty food distribution, etc.”
Over the past few years, operators have established multiple 4G smart shopping malls based on location-based services in certain cities and joint industry chain enterprises.
The ideal is full: to bring customers a wealth of value-added services such as indoor positioning and navigation based on the mobile 4G network, WeChat shake and accurate promotional information push based on geographic electronic fences, and convenient car search and payment, through member activities and discountsActivities, precision marketing activities, etc. to attract customers to the mall; improve the offline shopping experience of customers by providing convenience and optimizing services, so that customers can come again; also help mall managers and merchants build through real-time heat map monitoring and historical flow analysisThe smart shopping environment increases the residence time of customers in shopping malls, increases sales, and realizes a win-win business ecosystem for operators, shopping malls and consumers.
However, the reality is also skinny. For many individual users, in addition to the obvious location service experience for various navigation apps and consumer apps that involve positioning, they are relatively sensitive to free Wi-Fi in shopping malls and mobile phone numbers.The location services of the operators do not have much intuitive feeling.
An IT staff in a mall previously said that if the management department of the mall wants to optimize operation based on the newly constructed real-time heat map and flow analysis of customers, compared with the technical system, the overall awareness and ability of the IT department needs to be improved.
Location service is a gold mine. If the municipal department has already enjoyed the accuracy and efficiency of big data lock + information push service for weather warning, disaster notification, epidemic prevention and control, etc., then more companies have a positionThe service just needs and individual users are accustomed to the reality of the free APP service model. How should operators mine this gold mine?
Combining with 5G to obtain benefits from location services has become the latest and most important handle for operators and industry chains.
In the three major scenarios of 5G, mMTC focuses on low-power and large-capacity connections, uRLLC focuses on high-reliability and low-latency connections, and combined with increasingly mature IoT technologies, these two scenarios are considered to be more suitable for location services..
For example, the Environmental Protection Agency needs to know whether the water quality sensors placed in rivers and lakes are still working normally on the spot; smart home appliance manufacturers need to know the rough location of the white life cycle of white goods, and analyze the location of home appliances by big data to provide marketing, after-sales maintenanceGuarantee, personnel deployment, spare parts preparation materials provide decision-making basis.Such positioning requirements for massive mMTC IoT terminals will greatly enrich the application scenarios of operators’ 5G location services.
For location services in uRLLC scenarios, the most typical cases are drones and intelligent driving.
As industry experts Jiao Zongshuang and Zhang Xueying said, “5G + high-precision map + automatic driving” will be the high ground of location services.However, in the field of autonomous driving, China’s telecommunications operators are still relatively backward. In the market layout of “5G + high-precision map + automatic driving”, domestic operators mainly rely on their own network advantages to develop, lacking high-precision maps and autonomous driving.explore.According to the state’s plan for the development stage of autonomous driving, my country’s autonomous driving will enter the initial stage in 2020. The automobile industry will reach 30 million vehicles, and the market share of driver assistance/partial autonomous vehicles will reach 50%.In 2025, autonomous driving enters the development period, the scale of the automobile industry will reach 35 million, and the market share of highly autonomous vehicles will reach about 15%.By 2030, my country’s autonomous driving will enter a period of rapid development, the scale of the automotive industry will reach 38 million, and the market share of fully autonomous driving vehicles will approach 10%.
If telecom operators can fully absorb the advanced experience of external enterprises, and realize the integration of external technology and their own business development.While providing 5G network, combined with its own advantages in big data analysis, and working with the industry to work on smart transportation solutions and digging into the development of “high-precision maps + autonomous driving”, it is expected to dig out a gold mine of location services in the 5G era..
If, as experts say, “5G+Beidou” can be widely used in airport dispatching, unmanned aerial vehicles, robot inspection, etc., the commercial value of this gold mine will be even greater.
How to dig depends on the operator’s consciousness and actions.
