detailed description

The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to specific application scenarios and user requirements, and the unspecified implementation conditions are usually the conditions in routine experiments.

Example

According to the current popularization of mobile terminals, the terminal uses Android smartphones as an example to describe the method of implementing Wi-Fi-based terminal mobile services in large supermarkets. The supermarket has deployed a wireless network, a server and a database applying the method. As shown in Figure 1, the method includes the following steps:

(1) The user accesses an AP through an Android mobile phone, and sends a positioning request to the server through the mobile browser;

(2) The AP sends the collected signal characteristics of the mobile phone to the server, and the positioning unit of the server executes the positioning algorithm to determine the position of the mobile phone;

(3) The server extracts advertisements from the database, especially those related to the location of the user's mobile phone, and sends them to the mobile phone together with the supermarket map;

(4) Display the user's real-time location in the supermarket, selectable services, and play pushed advertisements on the mobile phone.

(5) Users can order and search for advertisements they are interested in;

(6) Users can select the products and infrastructure they want to locate through the advertisement and search functions, send location requests to the server, and obtain information query and navigation services;

(7) Users can make positioning requests for people in the supermarket, but this is limited, and the specific services are provided by the supermarket manager;

(8) Users can choose other value-added services derived from positioning;

(9) The user can choose to cancel the positioning, or directly close the browser to cancel.

In this example, enough wireless APs are arranged in the supermarket to realize positioning. Each AP is connected to a server, and the server can access a database containing information such as advertisements and maps. In actual operation, it is not necessary for every AP to provide access services for the terminal, and some APs can only play the role of positioning. At the same time, the entire wireless network provides Wi-Fi roaming services for terminals entering the supermarket to ensure continuity of positioning. The wireless network can provide users with access to the Internet at the same time.

There are two ways for Wi-Fi to collect location information. In the first type, the user terminal collects signal characteristics of nearby active APs, such as signal strength, and submits them to the server through the accessed AP. This method requires the user to install a client to collect AP signals, and all subsequent positioning-related services will be implemented in the client. The second way is that after the user sends a positioning request, the AP near the user collects the signal characteristics of the terminal and forwards it to the server. This method does not depend on a certain client, and a location request can be sent through a browser, and subsequent location-related services will be implemented in the webpage of the browser window. Both methods are feasible, and obviously the second one is more versatile. Therefore, in this example, after the mobile phone is connected to an AP, open the browser and enter any URL, the location authentication interface will automatically pop up, and the user can choose the location Or access Internet services.

In this example, the positioning unit of the server runs a positioning algorithm, and the characteristic of the wireless signal collected for positioning refers to signal strength (RSSI). There are many RSSI-based positioning algorithms, for example, a location fingerprint recognition algorithm may be used. The algorithm starts with a reasonable distribution of reference points to ensure that sufficient information can be provided for accurate position estimation in the positioning phase. Then measure the RSSI values from different APs at each reference point in turn, and record the corresponding MAC addresses and the location information of the reference points in the database until all reference points in the area are traversed. After the location information database is established, the collected RSSI information can be compared with the existing data, and an algorithm can be run to calculate the estimated location value.

In this example, the contents of the database used mainly include location information required for positioning, advertisements, supermarket internal maps for query and navigation, product information, infrastructure information, user information, and the like. The location information of commodities and basic facilities in the supermarket must be stored in the database. Since advertisements, commodities, and map data are associated, a relational database is preferred.

In this example, the owner of the database is the manager of the supermarket. They need to maintain the wireless network, the normal operation of the server, update advertisements and product information, and collect statistics on user behavior. The supermarket can hand over the technical responsibilities to a third-party professional company. The supermarket has the right to decide the content of the advertisement, so it can charge the advertiser a certain fee.

Fig. 2 is a schematic diagram of the screen display of the mobile phone provided by the present invention after receiving the positioning. Among them, 201 is a positioning map, and 202-205 successively indicate the mobile service buttons provided: advertisement on demand, search, crowd positioning, and value-added services. Through search and advertisement on demand, you can enter object positioning and navigation services. Push advertisements are played in some areas shown in 206 . 207-209 are keys of the mobile phone in turn: function key, menu key, and return key.

In this example, the advertisement pushed by the server is played in the lower area of the screen. The playing format includes text, picture, video, and voice, and the content is preferentially a product advertisement adjacent to the current location of the user terminal. For example, when the user comes to the toiletry area, the toiletry advertisement is automatically pushed; it can also be irrelevant to the current location. Promotional advertising. Advertisements are changed at regular intervals. Users can click the advertisement below to expand reading and obtain further services.

In Figure 2, the user can select the "Advertisement on Demand" button to view what promotional activities are currently available in the supermarket, as well as advertisements for different commodities. The product advertisement classification is presented to the user, and the user selects the product type and displays the corresponding advertisement list. Users can also directly query the advertisement of a product through the search button. When the user wishes to look at the product promoted in the advertisement, the positioning navigation service can be activated to give the position of the product in the supermarket.

In this example, users can also use the search function to query the products they are interested in or want to buy; the server will not only provide information such as the production date, ingredients, and types of the products, but also give the location of the products in the supermarket on the map. And give the optimal path to go. Because the flow of people in different areas of the supermarket is different, the server can find a path with a short distance and less traffic according to the number and location of connected terminals. Users can also query the location of supermarket facilities such as toilets, electronic scales, storage areas, etc., and request navigation services. Whether it is locating objects or crowds, it is closely coordinated with the map. Basic map operations such as dragging and zooming are supported in this example.

In this example, the user can select the crowd positioning service. Such positioning is limited due to the location privacy issues involved with other end users. However, here are several possible positioning services: 1. The user chooses to view the flow of people in the entire supermarket or a certain area; 2. If user B enables user A's location to be visible, A can obtain B's location in the supermarket in real time and Movement path; 3. When the user wants to pay and checkout, the server will recommend to the user the cashier counter that takes the least time to checkout according to the flow of people and service speed at each cashier counter. The historical data generated by crowd positioning can be used for crowd behavior analysis of supermarket operators, thereby improving management and services.

In this instance, users can choose value-added services derived from location. For example, register and log in, become a member of the supermarket, evaluate the products and services of the supermarket, and obtain rewards and discount services; pay to access the Internet, obtain a wider range of product information, and make comparisons; Push advertisements can be turned off; users can add their favorite products to the electronic shopping cart for the convenience of next purchase; users can customize specific product advertisements, and every time the user visits the supermarket, the advertisements that the user needs will be pushed.

In this instance, the user can end the service by canceling the positioning button or closing the browser. For a registered user, his relevant service data will be saved in the database, which is convenient for the user to log in and query next time.

The above-mentioned preferred examples are only to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention shall fall within the protection scope of the present invention.
