Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a system and method for measuring speed of all people based on character portraits. Background Art

[0002] In order to improve customer satisfaction, all major operators have provided a national speed test system similar to China Telecom. Through this system, home users can independently evaluate the quality of their home WIFI; installation and maintenance personnel can associate users to enable installation and maintenance tools; community networks support differentiated services in network health communities; and evaluation specialists guide users to test speeds. Take China Telecom's national speed test system as an example: One-click speed test: Through the user's self-service use of the WIFI speed test perception applet, the quality of the home WiFi network is detected, and the user's poor perception of WiFi network quality is proactively discovered. Poor quality users are remotely identified, target users are determined, support is provided for exploring business opportunities for whole-house WiFi products, and assist front-line marketing.

[0003] Network quality health report: Visualize network quality health report to enhance users' awareness of operators' network services, guide users to understand home network problems, obtain door-to-door service opportunities, and expand marketing channels.

[0004] Satisfaction evaluation mechanism: Based on the analysis of user online behavior, an evaluation model from test indicators to user perception is established, and Internet incentive policies are used to effectively promote user participation in surveys and continuously follow up on customer satisfaction.

[0005] Support installation and maintenance pre-processing: Installation and maintenance users can log in to the applet to test the home WiFi speed, obtain the home WiFi quality report of the nearby community grid, and make accurate appointments for door-to-door repairs, providing efficient door-to-door service.

[0006] Rewarded evaluation: Users can get corresponding points by using the mini program to test speed, sign in, forward, etc., and can directly redeem gifts in the mini program mall. Filling out the satisfaction questionnaire, uploading speed test screenshots, and applying to become a network quality supervisor can all get a health gift package.

[0007] Smart installation and maintenance: After users use the mini program to test their speed, they can directly make an appointment for door-to-door installation and maintenance services. After the installation and maintenance personnel authenticate their identity in the mini program and forward the information, they can associate the speed test user, obtain the associated user evaluation data, and respond to the network quality optimization needs of users on this network.

[0008] Differentiated services: Carry out grid "all-people speed test" community operation activities, cooperate with the operator's brand QoE community presentation, innovate service brand building, and guide community users to feedback their demands through appropriate channels.

[0009] In short, the "National Speed ​​Test" system hopes to integrate speed testing, satisfaction improvement, points mall, door-to-door installation and maintenance, marketing conversion and other functions, introduce rewards to activate broadband users to evaluate the intranet quality report, and import the installation and maintenance personnel data center, and ultimately hope to improve customer satisfaction, achieve the goal of maintaining the existing customer base, and stimulate new customer bases. However, the actual situation is that the customer base is insensitive to this application, cannot really feel the care of the operator, and cannot effectively stimulate new customer bases. The fundamental reason is that the current national speed test system only stays at the level of caring about user network quality and network parameters, and does not get closer to user needs based on the special attributes of the population.

[0010] Therefore, how to be closer to user needs and achieve the goal of further improving customer satisfaction is a problem that needs to be solved at present. Summary of the invention

[0011] The purpose of the present invention is to propose a speed measurement system and a speed measurement method for all people based on character portraits, so that the solution recommendations of each application are based on character portraits, thereby being closer to user needs and improving customer satisfaction.

[0012] In order to achieve the above object, the present invention provides a speed measurement system for all people based on character portraits, comprising: Character portrait subsystem, satisfaction improvement subsystem and multiple application subsystems; The character portrait subsystem collects basic character portrait information from the satisfaction improvement subsystem and multiple application subsystems when the system is initialized; and establishes a character portrait set for each user according to different application scenarios of each user in each application subsystem; When the national speed test system receives a user's request for a solution recommendation for the application subsystem, the character portrait subsystem outputs a plurality of application solutions with the highest satisfaction associated with the corresponding character portrait according to the character portrait set and the application category of the application subsystem combined with the network quality information, and recommends them to the corresponding application subsystem for execution; After the application subsystem is executed, the satisfaction improvement subsystem tracks the user's satisfaction feedback and updates it to the character portrait subsystem; At the next request, the character portrait subsystem outputs multiple application solutions with the highest satisfaction scores based on the latest character portrait set and recommends them to the corresponding application subsystems for execution.

[0013] In an optional solution, the application subsystem includes: a speed measurement subsystem, which is used to collect user speed measurement initiation time, test frequency, download rate, upload rate, network delay, and network jitter.

[0014] In an optional solution, the application subsystem includes: the points mall subsystem, which is used to collect the user's purchased products, categories, price ranges, points ranges, and whether they are pure points redemption.

[0015] In an optional solution, the application subsystem includes: a marketing conversion subsystem, which is used to collect information on the category, price range, timeliness and satisfaction of users purchasing new recommended packages.

[0016] In the optional solution, the national speed measurement system also includes an on-site installation and maintenance subsystem, which is used to collect information about the user's education level, house type, contracted uplink bandwidth, downlink bandwidth, Internet usage, installation and maintenance timeliness score, and installation and maintenance quality score at home, and feed the information back to the character portrait subsystem.

[0017] In an optional solution, the satisfaction improvement subsystem is used to collect users' evaluation time, evaluation timeliness, satisfaction score, expectation score, and recommendation score for the recommended solution.

[0018] In an optional solution, the character portrait subsystem establishes and updates a character portrait set based on customer satisfaction based on various information collected by the speed measurement subsystem, points mall subsystem, satisfaction improvement subsystem, installation and maintenance subsystem, and marketing conversion subsystem.

[0019] The present invention also provides a method for measuring speed of all people based on character portraits, comprising: Step 1: Collect the user's personal attribute data and behavioral characteristic data to establish a collection of basic information about the character portrait; Step 2: When the user initiates a corresponding recommendation request to each subsystem of the system, several solutions are recommended to the user based on the set of basic information of the character portrait and network quality information; Step 3: Track user satisfaction feedback on the recommended solution. If the evaluation is lower than the threshold, arrange installation and maintenance personnel to collect accurate user personal attribute data and behavioral characteristic data to update the basic information of the character portrait. If the evaluation is higher than the threshold, receive the update request of the basic information of the character portrait from each subsystem and update the basic information of the character portrait. Step 4: When the user initiates a corresponding recommendation request to each subsystem of the system again, steps 2 and 3 are repeated.

[0020] The beneficial effects of the present invention are: When recommending application solutions, the present invention does not recommend a certain solution in a stereotyped manner, or determine the recommended solution based on a certain marketing strategy of the operator. The recommended application solutions are closely combined with user portrait information, so that the solution is closer to user needs and greatly improves customer satisfaction. In addition, user portrait information is not static. After the user uses it, the satisfaction evaluation will be collected, and the user feature data will be accurately collected, so that the customer satisfaction score of each application solution based on the character portrait set will be higher and higher.

[0021] Furthermore, for users with large evaluation deviations, door-to-door installation and maintenance services are provided to collect more accurate information, so that the national speed measurement system based on character portraits is closer to user needs and can greatly improve customer satisfaction.

[0030] Example 1 Reference Figure 1 This embodiment provides a speed measurement system for all people based on character portraits, including: Character portrait subsystem, satisfaction improvement subsystem and multiple application subsystems; The character portrait subsystem collects basic character portrait information from the satisfaction improvement subsystem and multiple application subsystems when the system is initialized; and establishes a character portrait set for each user according to different application scenarios of each user in each application subsystem; When the national speed test system receives a user's request for a solution recommendation for the application subsystem, the character portrait subsystem outputs a plurality of application solutions with the highest satisfaction associated with the corresponding character portrait according to the character portrait set and the application category of the application subsystem combined with the network quality information, and recommends them to the corresponding application subsystem for execution; After the application subsystem is executed, the satisfaction improvement subsystem tracks the user's satisfaction feedback and updates it to the character portrait subsystem; At the next request, the character portrait subsystem outputs multiple application solutions with the highest satisfaction scores based on the latest character portrait set and recommends them to the corresponding application subsystems for execution.

[0031] Specifically, in this embodiment, the application subsystem includes: a speed measurement subsystem, a points mall subsystem, and a marketing conversion subsystem. The speed measurement subsystem is used to collect information such as the time when the user's speed measurement is initiated, the test frequency, the download rate, the upload rate, the network delay, and the network jitter. The points mall subsystem is used to collect information such as the products, categories, price ranges, points ranges, and whether they are pure points redemption purchased by users. The marketing conversion subsystem is used to collect information such as the categories, price ranges, timeliness, and satisfaction of users' purchases of new recommended packages.

[0032] In this embodiment, the national speed measurement system also includes an on-site installation and maintenance subsystem, which is used to collect information about the user's education level, house type, contracted uplink bandwidth, downlink bandwidth, Internet usage, installation and maintenance timeliness score, and installation and maintenance quality score at the doorstep, and feed the information back to the character portrait subsystem.

[0033] The satisfaction improvement subsystem is used to collect the evaluation time, evaluation timeliness, satisfaction score, expectation score, and recommendation score of the recommended solution by the user. The satisfaction improvement subsystem is used to evaluate the acceptance of the recently recommended solution. The character portrait subsystem establishes and updates a character portrait set based on customer satisfaction based on various information collected by the speed measurement subsystem, the points mall subsystem, the satisfaction improvement subsystem, the home installation and maintenance subsystem, and the marketing conversion subsystem.

[0034] The working principle of this embodiment is as follows: First, based on the ITMS and cloud platform technology of telecommunications, combined with network perception neuron technology, a national speed measurement system is established, which consists of a speed measurement subsystem, a satisfaction improvement subsystem, a points mall subsystem, a door-to-door installation and maintenance subsystem, a marketing conversion subsystem, and a character portrait subsystem. Second, when the system is initialized, the character portrait subsystem collects basic character portrait information from the speed measurement subsystem, the points mall subsystem, the satisfaction improvement subsystem, the door-to-door installation and maintenance subsystem, and the marketing conversion subsystem. Third, the character portrait subsystem establishes a character portrait set for each user according to the different application scenarios of each user in each subsystem, and gives a customer satisfaction score based on historical data during initialization. Fourth, when the national speed measurement system receives a user's speed measurement, points exchange or marketing conversion recommendation request, the character portrait subsystem outputs the corresponding character portrait-associated application solutions with the highest satisfaction according to the user's login information and the subsystem application category and recommends them to the corresponding application subsystem for execution. Fifth, after each application subsystem is executed, the satisfaction improvement subsystem is notified to collect the satisfaction score of the application solution based on the character portrait. Finally, the character portrait subsystem updates the customer satisfaction score of each application solution based on the evaluation information of the satisfaction improvement subsystem. When the next request is made, the latest character portrait-based solution with the highest satisfaction score will be provided based on the user information, and will be recommended to each application subsystem first. If the final evaluation of a user is significantly different from the internal score of the character portrait subsystem, the on-site installation and maintenance subsystem will be notified to provide on-site services and collect accurate character feature data.

[0035] Based on this system, it can be achieved that: the character portrait subsystem collects basic information such as the user's house type, education level, Internet usage, hobbies, etc., rather than just the traditional network quality information. When recommending user solutions, the marketing conversion system not only uses the traditional network quality information, but also combines the user's personal attributes, behavioral characteristics and network quality to form character portrait information, and further screens and recommends application solutions with higher satisfaction. The satisfaction improvement subsystem evaluates the acceptance of the recently recommended solutions and feeds back to the character portrait subsystem. When the installation and maintenance personnel visit the door-to-door system, they further obtain more accurate character portrait information (the user's house type, education level, Internet usage, hobbies) and add it to the character portrait system. The subsequent national speed measurement system will make recommendations based on more accurate character portrait information, so that marketing conversion solutions, speed measurement solutions, and points mall applications are all displayed or recommended based on character portraits, which is closer to user needs and achieves the goal of further improving customer satisfaction.

[0036] Example 2 This embodiment provides a method for speed measurement for all people based on character portraits, including: Step 1: Collect the user's personal attribute data and behavioral characteristic data to establish a collection of basic information about the character portrait; Step 2: When the user initiates a corresponding recommendation request to each subsystem of the system, several solutions are recommended to the user based on the set of basic information of the character portrait and network quality information; Step 3: Track user satisfaction feedback on the recommended solution. If the evaluation is lower than the threshold, arrange installation and maintenance personnel to collect accurate user personal attribute data and behavioral characteristic data to update the basic information of the character portrait. If the evaluation is higher than the threshold, receive the update request of the basic information of the character portrait from each subsystem and update the basic information of the character portrait. Step 4: When the user initiates a corresponding recommendation request to each subsystem of the system again, steps 2 and 3 are repeated.

[0037] Specifically, step S101: Initialization of the national speed measurement system: Based on the ITMS and cloud platform technology of telecommunications, combined with network perception neuron technology, a national speed measurement system is established. The system consists of the following six subsystems (see Figure 1 ): speed measurement subsystem, satisfaction improvement subsystem, points mall subsystem, door-to-door installation and maintenance subsystem, marketing conversion subsystem and character portrait subsystem. Go to step S102; Step S102: Collect parameters: 1) On-site installation and maintenance subsystem: collects information such as the user's education level, apartment type, contracted uplink bandwidth, downlink bandwidth, and Internet usage (watching videos, playing games, browsing the web, office work, downloading, and other), installation and maintenance timeliness score, and installation and maintenance quality score.

[0038] 2) Speed ​​test subsystem: collects information such as the time when the user initiates the speed test (time period of each day), test frequency (number of speed tests initiated per month), download rate, upload rate, network latency, network jitter, etc.

[0039] 3) Satisfaction improvement subsystem: collects user evaluation time, evaluation timeliness, satisfaction score, expectation score, recommendation score, etc.

[0040] 4) Points Mall Subsystem: collects information such as the products purchased by users, categories, price ranges, points ranges, and whether they are pure points redemption.

[0041] 5) Marketing conversion subsystem: collects information on the categories, price range, timeliness and satisfaction of users’ purchase of new recommended packages.

[0042] After the basic character portrait information is collected, proceed to step S103.

[0043] Step S103: Establishing character portraits: The character portrait subsystem establishes a character portrait set based on customer satisfaction after collecting these basic information. For example, a certain portrait information is as follows: 1. Users with a bachelor's degree, who often watch videos, have an upstream rate of 100Mbps and a downstream rate of 300Mbps. When the network speed reaches 100Mbps, the satisfaction is 99 points. 2. Users with a bachelor's degree, who often watch videos, have an average monthly traffic of 50G, a maximum of 70G, and a minimum of 30G. The satisfaction of package A is 60 points, that of package B is 80 points, and that of package C is 99 points. 3. Users with a bachelor's degree, who browse the web, have an upstream rate of 100Mbps and a downstream rate of 300Mbps. When the network speed reaches 10Mbps, the satisfaction is 99 points. At this point, enter step S104.

[0044] Step S104: National speed test application: According to the user's characteristics and current behavior, several solutions with the highest satisfaction are recommended for the user to choose. That is, according to the user's login information for logging into the national speed test system, the sub-function module selected by the user, the user's current login time and other information, the user's satisfaction profile information is confirmed. Example 1: When the user enters the speed test system, the user's personal attribute information can be obtained, and then the profile information is obtained according to the application selected by the user (undergraduate degree, users who often watch videos, users with an upstream rate of 100Mbps and a downstream rate of 300Mbps, and users who are sensitive to download speeds between 19:00 and 21:00). Then, in the speed test interface, the download speed test entrance is displayed first. And test the download speed of major well-known video download websites that users care about. Instead of displaying the speed test page in a stereotyped way. Example 2: After the user completes the speed test, the marketing conversion subsystem obtains the profile information based on the user's personal attribute information (bachelor's degree, frequent video watcher, average monthly traffic of 50G, maximum of 70G, minimum of 30G. Satisfaction with package A is 60 points, package B is 80 points, and package C is 99 points.), then in the package change interface, it is displayed to the user in the above-mentioned order of satisfaction, rather than recommending a certain plan in a stereotyped manner, or determining the recommended plan based on a certain marketing strategy of the operator. When the user completes an application, it proceeds to step S105.

[0045] Step S105: Satisfaction evaluation: Track user satisfaction feedback and update user portrait basic information (enter step S107). The fundamental starting point of the national speed test system is to improve user satisfaction. Therefore, after the user completes an application, the satisfaction improvement subsystem will track the user's satisfaction feedback in a timely manner and update it to the character portrait subsystem. Subsequent solution recommendations will be based on the latest customer satisfaction evaluation character portrait information. If a user's evaluation is low, proceed to step S106.

[0046] Step S106: On-site maintenance: When the maintenance personnel visit the site, they will further obtain more accurate character portrait information (user's house type, education, Internet usage, hobbies) and add it to the character portrait system. The subsequent national speed test system will make recommendations based on more accurate character portrait information, so that marketing conversion plans, speed test plans, points mall and other applications are displayed or recommended based on character portraits, which is closer to user needs and achieves the goal of further improving customer satisfaction.

[0047] Step S107: Update basic character portrait information: receive update requests for basic character portrait information from each subsystem, and update basic user attributes or user behavior information.

[0048] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
