Please refer to FIG. 1, which shows a flowchart of a service providing method shown in an embodiment of the present application. In this embodiment, the service provision method is used in a terminal with positioning and navigation functions as an example for description, and the method includes:

Step 101: Turn on the subway mode.

Optionally, the subway mode is a mode set in the terminal to provide users with travel services when they take the subway, which can help users inquire about routes, stations, timetables, and other information. The subway mode in the embodiment of this application has the function of providing convenient services for special groups of people.

In a possible implementation manner, the terminal obtains the user location information in real time, and when it is determined that the user enters the subway station according to the user location information, the subway mode is automatically turned on. In another possible implementation manner, when the user uses a payment application to swipe his card to enter the station, the terminal confirms to enter the subway station and turns on the subway mode.

Of course, in addition to automatically entering the subway mode through the above method, the user can also manually turn on the subway mode, which is not limited in this embodiment.

Step 102: Determine the current station in response to a preset riding scene in the subway mode. The preset riding scene is a scene of a preset crowd riding the subway, and the preset crowd includes at least one of the elderly, children, and disabled persons.

In a possible implementation manner, after the terminal enters the subway mode, it further determines whether it is currently in a preset riding scene, that is, whether it is necessary to provide corresponding services to the current user during the subway ride. For the method of determining whether it is in a preset riding scene, optionally, the riding scene selection interface is displayed first. When the user selects a preset riding scene that provides services for a preset crowd, the terminal enters the preset riding scene and determines the current station .

In another possible implementation manner, the terminal may determine whether the user belongs to a preset group of people according to the historical data of the user, so as to determine to enter the preset riding scene when it is recognized that the user belongs to the preset group of people. For example, when the terminal detects that a learning APP is installed, it determines whether the user is a child by obtaining the age range of the user group corresponding to the APP; when the terminal detects that the font size of the system font is large, the user is determined to be an elderly person.

Optionally, each time the subway arrives at a station, the terminal will re-determine the current station and update the arrival information in real time.

Optionally, the user can select a default preset riding scene in the subway mode, and when the terminal enters the subway mode, it automatically enters the preset riding scene.

Step 103: Determine a site service corresponding to the current site according to the current site and the destination site, and the site service includes at least one of arrival reminder, location sharing, and destination site navigation.

The station services for unused stations may be different. Optionally, the arrival reminder is used to remind the user of the current station when the subway arrives at the station, so as not to miss the subway station announcement information or see the station information in the subway car; Sharing is to share the user's current location with family, friends, etc., to grasp the user's dynamics in real time, and to discover in time when there is an abnormality in the user's dynamics; the destination site navigation is used to help the user exit the station, and can plan a suitable outbound route for the user.

In a possible implementation manner, each time the subway arrives at a station, the terminal determines the station service corresponding to the current station according to the relationship between the current station and the destination station. Among them, the destination site can be manually entered by the user when the subway mode is turned on; it can also be automatically filtered according to the user's historical travel records, and if the user changes the itinerary, the destination site will be reselected.

Step 104: Provide site services.

The terminal provides users with site services corresponding to the current site. Illustratively, when the terminal determines that the current site is the destination site, it will remind the user of arrival and navigation of the destination site, and remind the user to get off the car in time and leave the station safely.

To sum up, in the embodiment of this application, the terminal is preset with subway mode riding scenes for the elderly, children, and the disabled. After the terminal enters the preset riding scene, when the subway arrives at a certain station, it is determined The current site, and based on the relationship between the current site and the destination site, determine the site services that the current site should provide. The site services include at least one of arrival reminders, location sharing, and destination site navigation, which can promptly remind users of the current site. It also provides users with outbound navigation of the destination site, which improves the convenience of subway travel for special groups.

In a possible implementation manner, in order to further simplify user operations and facilitate the preset crowd to quickly switch to the preset riding mode when riding, the terminal automatically judges based on the user's historical data when the user does not actively set the riding scene Whether the user belongs to a preset crowd, and it is recommended to switch to the preset riding scene when it is determined to belong to the preset crowd. The service providing method in the embodiment of the present application further includes the following steps:

1. The account label is determined based on historical usage data. The historical data includes at least one of account information, application types of historically running applications, and system setting data. The account label is used to indicate the user type.

For example, when the terminal detects that a learning app is installed, it determines whether the user is a child by obtaining the age range of the user group corresponding to the app; when the terminal detects that the font size of the system font is large, the user is determined to be an elderly person; or, the terminal Determine the account label directly based on the age in the account information set by the user.

2. In response to the account label indicating that the user type belongs to a preset group of people and is not in a preset riding scene, a prompt message for switching riding scenes is displayed.

When the terminal determines that the account label of the currently logged-in account is the account label of the preset group of people, and the interrupt is not currently in the preset riding scene, the terminal interface displays the prompt message for switching the riding scene, and displays the control for switching the riding scene, so as to preset When the crowd has not set the riding scene, the terminal can quickly enter the preset riding scene after the subway mode is turned on, thereby simplifying user operations and providing convenience for the preset crowd.

Please refer to FIG. 2, which shows a flowchart of a service providing method shown in another embodiment of the present application. In this embodiment, the service provision method is used in a terminal with positioning and navigation functions as an example for description, and the method includes:

Step 201: Turn on the subway mode.

In a possible implementation manner, the terminal may automatically turn on the subway mode according to the current application scenario, and step 201 may include the following steps A and B:

A. Get the interface information of the current user interface.

For the user who enters the station by brushing the code, the terminal can obtain the user interface (UI) interface information through the system embedding point. In a possible implementation manner, the developer performs the system embedding point for the application related to the service provision method in advance. . As shown in Figure 3, the Android system embedded points 306 are preset in the terminal. These embedded points mainly include WiFi information, APP switching, location, bright screen, and Bluetooth. According to the Android system embedded points 306, the terminal can check the geographic location, The user's activities and application usage information are collected and identified. In the embodiment of the present application, the interface information is obtained through APP switching in the Android system embedded point 306.

Schematically, please refer to FIG. 8, which shows a schematic diagram of an application system embedding point. The left side is the view tree 801 of the system embedding point, and the right side is a corresponding UI interface 802, which can be seen from the figure. Out, each text information and image information in the UI interface 802 has a corresponding system embedded point in the view tree 801, for example, the outbound text view on the left "Successful Outbound-Longhua Middle Road" 803 corresponds to the UI interface 802 on the right In the text box "Successfully Outbound-Longhua Middle Road" 804.

B. In response to the current user interface containing the interface information of a successful pit stop, turn on the subway mode.

When the terminal detects the UI information containing the successful entry, it determines that the user enters the station and turns on the subway mode. Therefore, the user does not need to manually turn it on, which simplifies the operation steps.

Optionally, the terminal can automatically close the subway mode according to the interface information including the successful exit.

Or, for users who take card entry or other methods, the above steps A and B can be replaced with the following steps C and D:

C. Collect ambient sound through a microphone.

In a possible implementation manner, the terminal may turn on the microphone when detecting that the user is in a subway station according to the user's location, and collect ambient sound in real time.

D. Turn on the subway mode in response to recognizing that the ambient sound includes the alarm bell of subway door opening or closing.

The terminal recognizes the ambient sound, and when it recognizes the subway door opening or closing alarm bell, it determines that the user enters the subway station and automatically turns on the subway mode.

Step 202: In the subway mode, a contact setting interface is displayed, and the contact setting interface is used to prompt a preset group of people to enter the contact information of the emergency contact.

In a possible implementation manner, after the terminal enters the subway mode, the contact setting interface is displayed in the user interface, or the user manually opens the contact setting interface, and enters the contact information of the emergency contact in the interface.

Optionally, the number of emergency contacts is at least one, and the user needs to enter the contact's mobile phone number or communication software account in the contact setting interface.

Step 203: In response to receiving the contact information input in the contact setting interface, determine the preset riding scene in the subway mode.

In a possible implementation manner, the user inputs and submits the emergency contact's contact information, and the terminal can receive the emergency contact's contact information, thereby confirming to enter the preset riding scene.

Optionally, the user can select the default preset riding scene in the subway mode, set and save the contact information of the emergency contact, when the terminal enters the subway mode, it will automatically enter the preset riding scene and obtain the contact information of the emergency contact .

Step 204: In response to the preset riding scene in the subway mode, determine the operating state of the subway according to the sensor data. The operating state includes entering a station, exiting a station, stopping, and driving between stations.

Since the terminal provides services to users at various stations in the preset riding scene, it is necessary to obtain the operating status of the subway in real time, determine whether the subway arrives at the station, and provide related services.

In a possible implementation manner, the terminal uses a sensor algorithm to determine the operating status of the subway. As shown in Figure 3, an acceleration sensor is installed in the terminal. Through the sensor management component 301, the sensor data collected by the acceleration sensor is uploaded to the sensor classification system 302 through the secondary classification, and the processed sensor data is uploaded to the state machine 303 Finally, the operating status of the subway is determined according to the sensor data, where the terminal usually uses the vehicle detection algorithm 307 and the multi-line static detection algorithm 308 when performing data acquisition and secondary classification.

Schematically, as shown in Figure 4, it shows a data distribution diagram of an acceleration sensor. This segment of data is the subway acceleration value within 80,000 ms, the sampling rate is 100 Hz, and there are a total of 8,000 data points. The acceleration in the figure is relatively stable. Part of it corresponds to the stop state of the subway, the denser part with a small change range corresponds to the subway running between stations, and the part where the acceleration changes drastically corresponds to the running state of the subway leaving or entering the station.

Optionally, the terminal may also use sensor data collected by other sensors such as a speed sensor and a position sensor to determine the operating status of the subway, which is not limited in this embodiment of the application.

Optionally, the terminal can also use audio algorithms to determine the operating status of the subway. When the terminal detects the preset riding scene of entering the subway mode, it turns on the microphone and uses the microphone to collect ambient sound in real time. Input the audio classification system 305, and upload the processed result to the state machine 303, and judge whether the subway arrives at the station by identifying whether there is an alarm bell when the subway door opens or closes in the environmental sound.

Schematically, please refer to Figure 5, which shows the door opening and closing sound detection results of two subway lines. The left side is the spectrogram 501a of Metro Line 1 and the recognition result diagram 501b after audio recognition, and the right side is The spectral map 502a of Metro Line 12 and the recognition result map 502b after audio recognition. It can be seen from the figure that the alarm bells when the subway door is opened and closed are particularly obvious compared with other environmental sounds and can be easily identified. Therefore, the accuracy of using audio algorithms to determine whether the subway arrives at the station is relatively high.

Step 205: In response to the operating status being inbound or outbound, a mapping table is obtained, and the mapping table contains the corresponding relationship between the station and the base stations around the station.

When the terminal detects that the subway enters or exits the station, the current station needs to be updated. In a possible implementation manner, the terminal uses the base station to locate the station to determine the current station. Due to the limited coverage of base stations, usually 2 to 5 kilometers, and because the signal quality in the subway is poor, major operators will deploy more base stations in the subway line to ensure the signal in the subway, so in different sites, terminals Will be registered to different base stations.

Optionally, a mapping table is stored in the terminal. As shown in Table 1, the mapping table contains the corresponding relationship between each site and the base stations around the site.

Base station	subway station
mcc-460-mnc-00-ci-25935874-pci-435-tac-6270	Shanghai Metro Line 12_Longhua Middle Road
mcc-460-mnc-00-ci-142503585-pci-435-tac-6237	Shanghai Metro_Pujiang Line_Dongcheng First Road
mcc-460-mnc-00-ci-142503585-pci-435-tac-6237	Shanghai Metro_Pujiang Line_Huizhen Road

Table 1

Step 206: Determine the current site according to the mapping table and the base station information of the currently registered base station of the terminal.

In a possible implementation manner, the terminal obtains the base station information of the currently registered base station, and queries the corresponding base station in the mapping table to obtain the corresponding site, which is the current site. For example, the currently registered base station of the terminal is mcc-460-mnc-00-ci-25935874-pci-435-tac-6270, and the current station is determined to be Shanghai Metro_Line 12_Longhua Middle Road according to the mapping table.

Optionally, the mapping table is stored in the background server, and when the terminal detects the entry, it sends the base station information of the currently registered base station to the background server, and determines the current site according to the site information fed back by the background server.

Since the number of sites that a base station may correspond to is greater than 1, at this time, the current site cannot be determined directly according to the mapping table. In a possible implementation manner, step 206 includes the following steps 1 and 2:

1. In response to finding the site corresponding to the currently registered base station from the mapping table, and the number of sites is one, the site found is determined as the current site.

If the site corresponding to the currently registered base station in the mapping table is unique, the site can be determined as the current site.

2. In response to finding the site corresponding to the currently registered base station from the mapping table, the number of sites is at least two, and the neighboring site of the previous site is obtained; the intersection site of the found site and the neighboring site is determined as the current site.

If the number of sites corresponding to the currently registered base station in the mapping table is greater than 1, the current site cannot be directly determined. Considering that the proximity relationship of each station in a subway line is fixed, and before the terminal determines the current station, the displayed station is the previous station, so it can be determined by taking the intersection of the station corresponding to the current base station and the adjacent station of the previous station The current site.

In a possible implementation manner, the terminal stores information about each site of the current line, including the neighboring sites corresponding to each site. When the number of sites corresponding to the currently registered base station obtained by the terminal from the mapping table is greater than 1, the terminal obtains An adjacent station of a station (that is, the station displayed by the current terminal).

Optionally, the database of the back-end server stores the subway lines of each city, the terminal can upload the name of the previous site to the server, and the server queries the neighboring sites from the database and feeds it back to the corresponding terminal.

Schematically, please refer to Figure 6. In the subway line where the terminal is currently located, the coverage area of the base station 601 corresponds to the station A, the coverage area of the base station 602 corresponds to the station B, and the coverage area of the base station 603 corresponds to the station C and D, there is a site E corresponding to the coverage of the base station 604. The subway where the user is traveling is from station B to station C, and the station currently displayed by the terminal is station B. When the terminal detects that the subway is entering the station, the stations obtained by the current registered base station 603 are station C and station D, and the current station cannot be determined. Therefore, the terminal obtains the neighboring sites of the site B, and obtains the neighboring sites as sites A and C. By taking the intersection of the neighboring sites A and C and the sites C and D corresponding to the currently registered base station 603, the current site is obtained as the site C.

Optionally, if there are three or more sites on a line in the coverage area of a certain base station, the current site may not be determined by obtaining neighboring sites. At this time, the wireless fidelity (Wireless Fidelity, The WiFi) network determines the current site.

Step 207: In response to the current site being the target intermediate site, it is determined that the site service is arrival reminder and location sharing.

Among them, the target intermediate station is a station whose number of stations separated from the destination station is less than the threshold. In a possible implementation manner, the terminal is preset with a threshold, and when the destination site input by the user is received, the target intermediate site is determined according to the threshold, and the site service corresponding to the target intermediate site is arrival reminder and location sharing. For example, if the threshold is 5, when the user's subway arrives at a station 5 stations away from the destination station, the terminal will remind and share the location every time it arrives at a station. Optionally, the threshold can be set by the user.

Optionally, the user may also set every other stop from the starting station as a target intermediate station, or set each station to perform arrival reminder and location sharing, which is not limited in this embodiment.

Step 208: In response to the current site being the destination site, it is determined that the site service is arrival reminder, location sharing, and destination site navigation.

When the user arrives at the destination site, the terminal reminds the user to arrive at the destination site and get off the car in time through the arrival reminder site service; at the same time, in order to ensure that emergency contacts can know that the user has arrived at the destination site, location sharing services need to be provided, and SMS messages can be added when necessary Special reminders such as, vibration, etc., to prevent emergency contacts from missing messages; users need to continue walking for a certain distance after getting off the bus to leave the station. Therefore, the terminal provides site services for navigation of the destination site to help users exit the station smoothly.

Step 209: In response to the current site being another site, it is determined that the site service is an arrival reminder.

Among them, the current site is a site other than the target intermediate site and the destination site. In a possible implementation manner, the terminal judges whether the current site is the target intermediate site or the target site every time it arrives at a station, and if the current site does not belong to the target intermediate site and the target site, only the arrival reminder service is provided.

Different site services correspond to different functions. When the site service includes an arrival reminder, the terminal executes steps 210 and 211.

Step 210: In response to the site service being a site arrival reminder, a prompt message to arrive at the current site is generated.

When the terminal detects that the subway enters a station, it automatically generates prompt information to arrive at the current station. The prompt information includes the site name of the current station and transfer information, etc. The prompt information can be text or voice.

Optionally, if the current site is a target intermediate site or other sites, the prompt message can include the number of sites from the destination site, so that the user can get off the car in advance when they are about to arrive at the destination site.

Step 211: Display the prompt information in a preset manner.

Among them, the preset mode may be the default preset mode of the terminal, or it may be set by the user. For example, the preset mode can be voice prompt. When the terminal receives the instruction to remind the station, it will play the voice prompt through the speaker; the preset mode can also be text message and vibration, when the terminal receives the instruction to remind the station. , Vibrate and display related text messages in the current interface.

When the site service includes location sharing, the terminal executes step 212.

Step 212: In response to the site service being location sharing, share location information including the current site to emergency contacts.

The terminal generates the location information containing the current site, obtains the preset contact information of the emergency contact, and sends the location information to the terminal of the corresponding emergency contact to ensure that the emergency contact can obtain the geographic location of the user in real time.

Optionally, when the contact method is a mobile phone number, the terminal sends the location information by SMS; when the contact method is an account of a communication application, the location information is sent to the account of the corresponding application; when the emergency contact is serving the user When providing a friend whose method corresponds to an application, the terminal can directly send location information to the friend. When receiving a stop notification instruction sent by an emergency contact, the terminal will no longer send location information to the emergency contact's terminal.

When the site service includes destination site navigation, the terminal performs steps 213 and 214.

Step 213: In response to the site service being the destination site navigation, an outbound navigation route is generated, and the outbound navigation route is used to indicate a route from the current location to the barrier-free outbound facility.

In a possible implementation manner, when arriving at the destination site, the terminal obtains the location information of the barrier-free outbound facility in the destination site, and generates an outbound navigation route according to the location of the user and the location of the barrier-free outbound facility.

Optionally, the outbound navigation route may be multiple routes, or the best route automatically screened out by the terminal. The best route is the route with the shortest walking distance or the route with the least current flow of people.

Step 214: Display the outbound navigation route.

The terminal displays the outbound navigation route in the user interface in the form of a map, and at the same time turns on voice prompts to guide the user to safely and smoothly exit the station.

In the embodiment of the application, the user interface is switched to determine whether the user is on the subway, or the alarm bell of the subway door opens and closes the subway station, so that the subway mode of the terminal is automatically turned on, and the user does not need to manually turn on the subway mode, which simplifies the user's operation Steps: When the terminal is in the preset riding scene, the sensor data is used to determine the subway operating status and determine whether the subway arrives at the station. When the subway is detected in or out of the station, the current station is determined by using the terminal's current registered base station and the station corresponding to the base station Or the next station, no need to obtain the station announcement voice through the voice recognition model, low power consumption and high accuracy; provide different site services for different sites, timely arrival reminders, location sharing or destination site navigation to ensure emergency contacts It can grasp the dynamics of users, and can help users find barrier-free exit facilities and exit the station smoothly, which improves the convenience and safety of travel for special groups of people.

The subway station may be an indoor underground station or an outdoor station. Therefore, different stations need to use different methods for positioning and navigation. In a possible implementation manner, step 213 includes the following steps:

1. In response to the destination site being an outdoor site, the current location is determined according to the positioning component.

Outdoor sites usually do not have WiFi equipment, but the efficiency of outdoor receiving antenna radiation signal is high, so the current location can be determined directly according to the positioning component of the terminal, such as the Global Positioning System (GPS) component.

2. Generate outbound navigation routes based on the current location and the site map corresponding to the destination site.

Due to the inconvenience of the elderly, children, people with disabilities and other preset groups of people, they often need to use barrier-free outbound facilities, so the terminal obtains the location of the barrier-free outbound facilities at the destination site, and according to the current location and the location of the barrier-free outbound facilities, And the site map corresponding to the destination site generates the outbound navigation route.

In a possible implementation manner, when the destination site is an indoor site, the terminal performs the following steps three to six:

3. In response to the destination site being an indoor site, the current WiFi fingerprint is obtained. The current WiFi fingerprint is determined according to the terminal's received signal strength RSS of the WiFi signal, and the WiFi signal is transmitted by at least one WiFi device around the terminal.

The antenna radiation signal of an indoor site is usually weak, and it may not be able to generate a line quickly and accurately by directly relying on the positioning component. However, indoor sites are usually installed with multiple WiFi devices to meet people's network requirements, so WiFi signals can be used for positioning and navigation. In the embodiment of the present application, a WiFi-based location fingerprint method is used to complete the site service for target site navigation.

There are many types of location fingerprinting, and any feature that is helpful for distinguishing location can be used as a location fingerprint. Among them, the Received Signal Strength (RSS) is a feature necessary for the normal operation of most wireless communication devices. Many communication systems require RSS information to sense the quality of the link, achieve handover, adapt to the transmission rate, etc., and RSS is not affected by the signal bandwidth. Because of the influence of, high bandwidth is not required, so the acquisition of RSS is relatively simple. In this embodiment of the present application, RSS is used to obtain WiFi fingerprints.

In a possible implementation manner, the developer collects location fingerprints of each indoor site. First divide the site to obtain M grids, and then detect the RSS of each wireless access point (AccessPoint, AP) at a specific location (such as the grid center) of each grid, and obtain the RSS observation value of each grid. As shown in Figure 7, AP1 and AP2 are set in the indoor station 701, and the RSS of each grid to the two APs is detected respectively, and the RSS distribution of the indoor station 701 is obtained, as shown on the right side of Figure 7, and each network is represented by a vector. The RSS of the grid, this vector is the WiFi fingerprint. The developer enters the collected WiFi fingerprints into the WiFi fingerprint library of the corresponding site, stores it to the background server, and updates it in time.

When the terminal receives the instruction to perform the navigation service of the destination site, it obtains the RSS vector of the location in real time, that is, the current WiFi fingerprint.

4. In the WiFi fingerprint database corresponding to the destination site, the WiFi fingerprint with the highest matching degree with the current WiFi fingerprint is determined as the target WiFi fingerprint.

Among them, the matching degree can be calculated according to the Euclidean distance between the current WiFi fingerprint vector and each WiFi fingerprint vector in the WiFi fingerprint library. The calculation formula of Euclidean distance is:

Among them, N is the AP sequence number of the destination site, r _i is the vector of the current WiFi fingerprint, ρ _i is the vector of each WiFi fingerprint in the WiFi fingerprint library, and D is the Euclidean distance. The WiFi fingerprint with the smallest Euclidean distance from the current WiFi fingerprint is the target WiFi fingerprint. The principle can be referred to the right side of Figure 7, using the Tyson polygon method to draw the decision boundary. In the area contained by each Tyson polygon in the space, each point is closest to the WiFi fingerprint in the area. The current WiFi fingerprint is located in the Tyson Position in the polygon The position where the fingerprint is located, the current position of the terminal.

5. Determine the current location according to the location coordinates corresponding to the target WiFi fingerprint.

In a possible implementation manner, the background database stores the location coordinates of each WiFi fingerprint, acquires the location coordinates of the target WiFi fingerprint, and determines the location coordinates as the current location of the terminal.

6. Generate outbound navigation routes based on the current location and the site map corresponding to the destination site.

After the terminal opens the site service of the destination site navigation, it will determine the user's current location in real time and update it in the navigation route to remind the user whether it deviates from the outbound navigation route based on the user's dynamic location, and adjust the outbound navigation route in time according to the user's current location .

For the implementation of step six, reference may be made to step two above, which will not be repeated in this embodiment.

In the embodiments of this application, different methods are used for target site navigation for different sites. For outdoor sites, positioning components are used directly, and for indoor sites, location fingerprinting is used for navigation, which improves the accuracy of positioning and navigation, and does not require To obtain the location of the AP in advance, only need to detect the RSS of the terminal itself, which improves the efficiency of positioning and navigation and reduces the power consumption of the terminal.

In step 901, when the station entry is detected, the station arrival reminder function is turned on.

Step 902: When reaching the target intermediate site, perform location sharing.

Step 903: Determine whether the number of stations with the destination station is less than n. If yes, go to step 904; if not, go back to step 902.

Step 904: Send a special reminder to the emergency contact.
