Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, an application scenario diagram of the terminal payment method and apparatus provided in the embodiment of the present application is shown, as shown in fig. 1, a communication system 10 includes a terminal device 100 and a reading device 200, the terminal device 100 and the reading device 200 are located in a wireless network or a wired network, the terminal device 100 includes a communication module, and the terminal device 100 performs data interaction with the reading device 200 based on the communication module.

In some embodiments, the communication system 10 further includes a server 300, and the terminal device 100, the reading device 200, and the server 200 are located in a wireless network or a wired network, which may perform data interaction.

The terminal device 100 may be a portable electronic device such as a cell phone, a tablet computer, a wearable electronic device with wireless communication capabilities (e.g., a smart watch), etc., that also contains other functions such as personal digital assistant and/or music player functions. Exemplary embodiments of portable electronic devices include, but are not limited to, portable electronic devices that carry iOS, Android, Microsoft, or other operating systems. The portable electronic device may also be other portable electronic devices such as a Laptop computer (Laptop) or the like. It should also be understood that in other embodiments, the electronic device may not be a portable electronic device, but may be a desktop computer.

The terminal device 100 supports accessing to a Hotspot (i.e., Hotspot) of a Wireless Local Area Network (WLAN) through Wireless Fidelity (WiFi) to implement a network access function, and specifically, the terminal device 100 may include a Wireless network card or a WiFi chip for scanning and detecting Hotspot information. In an example, a user may selectively turn on or off a WiFi function of the terminal device 100 through a preset WLAN function switch, when the WiFi function of the terminal device 100 is in an on state, the terminal device 100 is in a detection state for a WiFi signal, a management program for WiFi connection and use may obtain hotspot information of the WiFi signal detected by the WiFi chip by calling a driver of the terminal device 100, where the hotspot information may include at least one of a Service Set Identifier (SSID), a physical address (Media Access Control, MAC) address, and the like. In one example, in combination with the SSID and the MAC as hotspot information, an index may be established according to the SSID, and then a specific WIFI hotspot may be determined according to the MAC.

It should be noted that the WLAN function switch is only a word used in the embodiment of the present application, and the meaning and function of the word are described in the embodiment of the present application, and the name of the word does not limit the embodiment of the present application; it is understood that in other embodiments of the present application, the above words may also use other names, such as WiFi function switch, etc.

The reading device 200 may be an electronic device having a communication function, which can perform data transmission with the terminal device 100, such as a (Point of Sale POS) terminal. In one example, the reader 200 may be an electronic device with Near Field Communication (NFC) function, and the terminal device 100 is provided with an NFC module inside, and may perform data interaction with the reader 200 based on the NFC module. When the reader 200 performs data interaction with the terminal device 100, the reader 200 sends an Application Identifier (AID) instruction to the terminal device 100 in the communication range of the reader, and after receiving the AID instruction, the NFC module of the terminal device 100 routes the AID instruction to an Application corresponding to the AID, so as to activate a corresponding analog card in the Application program and complete payment based on the analog card.

In another example, the reading device 200 may also be an electronic device with a code scanning function, in which an application capable of supporting code scanning payment is installed on the terminal device 100, and in response to an operation of the application by the user, the terminal device may open the application and display a code scanning payment page for the reading device 200 to read, thereby completing a code scanning payment process.

In daily life, more and more scenes are provided with reading equipment, such as (Point of Sale POS) terminals, and at least one of payment modes such as code scanning payment and NFC payment is supported, so that a user can realize convenient non-contact payment through interaction between the terminal equipment and the reading equipment. However, the inventor finds that, in research, when a user needs to use a terminal device for payment, the user often needs to perform a series of operations before selecting a required payment mode according to different scenes. For example, if code scanning payment is needed, the terminal device is often unlocked first, then an application supporting code scanning payment is selected, and a page for code scanning payment is opened; if NFC payment is needed, the user needs to set default payment on the terminal device to a corresponding payment card according to an actual scene before payment every time, and then the subsequent payment process can be completed. The steps of the payment method are complicated, and the payment efficiency is not high, so that the user experience is not good.

Therefore, in order to solve the above-mentioned defect, an embodiment of the present application provides a terminal payment method, which is applicable to the above-mentioned terminal device, as shown in fig. 1, and specifically, the method includes: s111 to S113.

S111: and detecting hotspot information.

The terminal equipment is provided with a WLAN module, a user can selectively turn on or turn off the Wifi function of the terminal equipment through a WLAN function switch, the terminal equipment can control the turning on or turning off of the WLAN module through detecting a trigger event of the WLAN function switch, the WLAN module is enabled to be in a working state when the WLAN module is turned on, and at the moment, the terminal equipment can detect hotspot information based on the WLAN module. The hotspot information may include at least one of a Service Set Identifier (SSID), a physical address (MAC) address, and the like.

At present, with the development of smart cities, public transport free Wifi gradually covers each big city, and public transport free Wifi is that a wireless hotspot is installed on a public transport means (such as a subway, a bus and the like) for free use of a user, so that the user can also connect to the internet and watch online videos and the like without using data connection when taking the public transport means. At this time, if the WLAN module of the user terminal device is in a working state, when the user waits at a bus station, a subway station, or nearby, or is already on the bus or subway, the terminal device may scan and detect the hotspot information of the WiFi signal of the bus or subway. In addition to public transportation scenarios, wireless hotspots are also used in many other scenarios, such as bank scenarios, shopping mall scenarios, etc.

In some embodiments, different wireless hotspots have different working ranges, and the larger the working range is, the farther a terminal device can detect hotspot information of the wireless hotspot. In one example, the working range of the wireless hotspot is generally dozens of meters, so taking a bus scene as an example, when a bus arrives at a station, or when a user arrives at a subway station to wait for a train, if the user is waiting for the bus to arrive at the station at the moment, the terminal device can be in the working range of the wireless hotspot of the bus no matter whether the bus arriving at the station is a route required by the user. If the user is riding or waiting for the subway, as the subway is generally provided with the wireless hot spots, the terminal equipment can scan at least for multiple times during the time of waiting for the train after the user enters the station with the terminal equipment, and the hot spot information of the wireless hot spot of the subway is scanned and detected.

The terminal equipment WLAN module also comprises a connection state and a non-connection state in the working state, wherein when the terminal equipment is accessed to the wireless hotspot and can surf the internet based on the accessed wireless hotspot, the WLAN module of the terminal equipment is in the connection state, and if the terminal equipment is not accessed to the wireless hotspot, the WLAN module is in the non-connection state. In some embodiments, in the disconnected state, the WLAN module may detect the hotspot information based on a default interval time, for example, once every 15 seconds, and the default interval time may be fixed or may be adjusted by a user). In addition, as an embodiment, if the terminal device is in the non-sleep state, the frequency of detection is higher than that in the sleep state. Therefore, by taking a bus scene as an example, the terminal device can scan the wireless hotspot of the bus or the subway before the bus/subway arrives/stops, and detect the hotspot information of the wireless hotspot.

S112: and when target hotspot information matched with the preset hotspot information is detected, determining the position information of the terminal equipment according to the target hotspot information.

The preset hotspot information is prestored hotspot information. In some embodiments, the preset hotspot information may include an SSID of the wireless hotspot, and may also include a partial string in the SSID of the wireless hotspot, for example, the SSID may be, for example, BUS-freeWiFi, SUBWAY-WiFi, CCB-WiFi, BC-WiFi, Mall-WiFi, or the like, and the preset hotspot information may be the SSID or the partial string of the SSID, such as BUS, SUBWAY, CCB, BC, Mall. Therefore, when the hotspot information is matched with the preset hotspot information, the target hotspot information can be determined through partial keyword matching, the coverage rate of the preset hotspot information on hotspot information matching is improved, and the usability is improved. In one example, the hotspot attributes such as the usage scenario of the wireless hotspot corresponding to the SSID may be determined according to the SSID of the hotspot information, for example, based on the foregoing example, the wireless hotspot corresponding to the SSID may be determined to be used for public transportation according to the SSID, such as BUS-freeWifi, similarly, the wireless hotspot corresponding to the SSID may be determined to be used for SUBWAY according to SUBWAY-WiFi, the wireless hotspot corresponding to the SSID may be determined to be used for bank according to CB-WiFi, and the wireless hotspot corresponding to the SSID may be determined to be used for shopping Mall according to Mall-WiFi.

In other embodiments, the preset hotspot information may include an SSID and a MAC address of the wireless hotspot, the detected hotspot information also includes the SSID and the MAC address, and a scene of the wireless hotspot corresponding to the SSID may be determined based on the SSID and the MAC address. In some examples, based on the big data collection, the geographical location of the wireless hotspot, the attribute of the hotspot such as the unit to which the wireless hotspot belongs can be judged according to the MAC address of the wireless hotspot. As an implementation manner, the terminal device may request, based on Google Mobile Service (GMS) of Google, to acquire a hotspot attribute corresponding to hotspot information from the GMS according to the hotspot information of the wireless hotspot. As another implementation, a database may also be built locally on the terminal device or in the server, so that the hotspot attribute corresponding to the hotspot information can be obtained according to the hotspot information.

In an embodiment, the terminal locally stores a preset database, the preset database includes at least one preset hotspot information, and the preset database may further include a hotspot attribute corresponding to each preset hotspot information. In one example, the preset database includes at least one preset hotspot message and a hotspot attribute corresponding to each preset hotspot message, so that the terminal device can obtain the hotspot attribute corresponding to the preset hotspot message based on matching with the preset hotspot message. Taking a public transportation scene as an example, the preset hotspot information may include an SSID of a preset hotspot, such as EGOBUS-WiFi, and the hotspot attribute corresponding to the preset hotspot information may include a city where the preset hotspot is located, such as shenzhen, so that when the terminal device detects that the hotspot information includes the SSID, such as EGOBUS-WiFi, the terminal device may determine that the city where the target hotspot corresponding to the target hotspot information is located is the shenzhen by matching with the preset hotspot information. Therefore, the preset database is stored in the terminal equipment so as to still be capable of quickly inquiring and matching when the network quality is poor, and the inquiring and matching efficiency is improved

In another example, the terminal device stores at least one preset hotspot message, and since SSIDs of some wireless hotspots contain information that can be used to determine hotspot attributes, for example, in a bus scenario, the hotspot message may include an SSID such as SZBUS-WiFi, and according to "SZBUS" in the SSID, the hotspot attribute of the hotspot message may be obtained, such as that a city where the wireless hotspot corresponding to the SSID is located is shenzhen. Therefore, the method can be realized only by storing the preset hotspot information. Therefore, the query and matching efficiency is improved, the storage pressure of the terminal equipment is reduced, and the operation processing efficiency of the terminal equipment is improved.

In other embodiments, the server is pre-configured with a preset database, where the preset database includes at least one preset hotspot message and may further include a hotspot attribute corresponding to each preset hotspot message. When the terminal device detects the hotspot information, a query request can be sent to the server, the server queries whether preset hotspot information matched with the hotspot information exists or not according to the hotspot information and returns a query result to the terminal device, the terminal device receives the query result returned by the server, whether the detected hotspot information is matched with the preset hotspot information or not can be determined, and the hotspot information which is successfully matched is taken as target hotspot information. The query result may include a result of whether to query, and when querying, the query result may further include the hotspot attribute of the matched preset hotspot information. The preset database is stored in the server, the terminal equipment is inquired and matched through the server, the storage pressure on the terminal equipment can be reduced, and the preset database is convenient to update when stored in the server, so that more and more comprehensive hot spot information can be continuously covered, and the usability is improved.

When the terminal device matches the detected hotspot information with the preset hotspot information and matches the detected hotspot information with the preset hotspot information successfully, the hotspot information which is matched successfully can be used as target hotspot information, and the position information of the terminal device is determined according to the target hotspot information. In some embodiments, the location information may be a relative distance between the terminal device and a target hotspot corresponding to the target hotspot information, or may be an absolute distance.

In one embodiment, the location information of the terminal device may be a relative distance between the terminal device and the target hotspot. In one example, according to the target hotspot information, the signal intensity corresponding to the target hotspot information detected by the terminal device can be determined, and according to the signal intensity, the relative distance between the terminal device and the target hotspot is determined and taken as the position information of the terminal device. The detailed description of the embodiments can be seen in the following examples, which are not repeated herein.

In another embodiment, the location information of the terminal device may also be an absolute distance between the terminal device and the target hotspot. In one example, the terminal device may obtain a geographic location, such as latitude and longitude coordinates, of the terminal device as location information based on the positioning function, and the terminal device may further obtain a MAC address of the target hotspot according to the target hotspot information, and determine the geographic location of the target hotspot according to the MAC address, thereby obtaining the geographic locations of the terminal device and the target hotspot, determining an absolute distance between the terminal device and the target hotspot, and using the absolute distance as the location information of the terminal device. The detailed description can also be seen in the following embodiments, which are not repeated herein.

In some other embodiments, the location information of the terminal device may also be determined according to the geographical location of the terminal device. In one example, the terminal device obtains its geographic location, such as latitude and longitude coordinates, and uses the geographic location as the location information of the terminal device.

S113: and when the position information meets a preset effective condition, controlling the terminal equipment to start a payment function corresponding to the target hotspot information.

In some embodiments, the manner of determining whether the position information satisfies the preset valid condition is different according to the difference of the position information. The position information of the terminal equipment can be used for representing the distance between the terminal equipment and a target hotspot corresponding to the target hotspot information, and when the distance meets a certain distance range, the payment function corresponding to the target hotspot information is started, so that false triggering can be effectively avoided, the accuracy of judgment on the intention of a user whether to start the payment function is improved, and it can be understood that the smaller the set distance range is, the less the position information is covered by the preset effective condition, the more cautious the starting is, and the lower the probability of false triggering is.

The terminal device can support multiple payment functions, each payment function can correspond to different payment applications, and different payment applications can correspond to different scenes, for example, the bus payment function is realized by using the bus payment application in a bus scene. Because the terminal device detects the target hotspot information matched with the preset hotspot information and when the position information meets the preset effective condition, the possibility that the user needs to pay is high, and the terminal device starts the payment function corresponding to the target hotspot information at the moment, the intention of the user that the payment needs to be started can be accurately judged, the payment function corresponding to the target hotspot information can be automatically started, the complicated operation is avoided, and the automatic selective payment can be realized without the manual operation of the user.

In an example, taking a BUS scene as an example, the target hotspot information includes an SSID such as BUS-freeWiFi, and when the position information satisfies a preset effective condition, it may be considered that a request for payment by using a BUS card exists on a BUS, at a BUS station, or near the BUS station, and at this time, a BUS payment function may be started so that the user can pay for getting on the BUS. Therefore, the terminal equipment can judge the current scene according to the hotspot information and control the starting of the payment function corresponding to the scene, so that the switching of the payment function is automatically controlled, manual operation of a user is not needed, and the payment efficiency is greatly improved.

In some embodiments, each payment function may further include one or more payment modes, the payment function may include a bus payment function including one or more bus payment modes, a bank payment function including one or more bank payment modes, and the like. Taking the bus payment function as an example, the bus payment mode may correspond to a bus card, for example, if the terminal device is required to support two types of bus card payment, the bus payment mode corresponding to the two types of bus cards may be preconfigured, for example, the bus card may be Shenzhen tong or Yangcheng tong, and the bus payment function may include a bus payment mode for performing payment based on Shenzhen tong and a bus payment mode for performing payment based on Yangcheng tong.

It should be noted that "payment function" and "payment mode" are only two terms used in the embodiments of the present application, and their representative meanings are already described in the embodiments of the present application, and their names do not constitute any limitation to the embodiments of the present application; it is understood that in other embodiments of the present application, the above words may also be used by other names.

In some embodiments, the terminal device may be used for multiple payment modes, such as two-dimensional code payment and NFC payment, and the payment modes are different based on different payment modes according to different payment modes of the terminal device, for example, the payment mode based on two-dimensional code payment, and the bus payment mode may correspond to two-dimensional codes corresponding to different bus cards; and based on a payment mode of NFC payment, the bus payment mode can correspond to a radio frequency card simulated by the NFC module based on the bus card.

In an implementation manner, the terminal device may be used for two-dimensional code payment, in a two-dimensional code payment mode, the terminal device needs to display a two-dimensional code for payment, and the reading device may perform interaction of a payment process by scanning the two-dimensional code displayed on a screen of the terminal device. When the location information of the terminal device meets the preset effective condition, starting a specific implementation mode of a payment function corresponding to the target hotspot information may include: and determining a payment application corresponding to the target hotspot information, and displaying a payment page of the payment application, wherein the payment page is used for being read by the reading equipment for payment.

For example, when the terminal device detects that the target hotspot information matched with the preset hotspot information includes an SSID (service set identifier), such as BUS-freeWiFi, the user can be considered to be in a BUS scene at present and possibly need to take a BUS, then the position information of the terminal device is acquired, when the position information meets a preset effective condition, the user can be considered to need to pay by BUS, and at the moment, a BUS payment function corresponding to the target hotspot information can be started, that is, a payment page of a BUS payment application corresponding to the target hotspot information is displayed, so that the reading device can read and complete payment. Therefore, the scene of the user can be judged according to the hotspot information without manual operation of the user, whether the user needs to pay is judged by combining the position information of the terminal equipment, when the position information meets the preset effective condition, the fact that the user needs to start the payment function in the scene is judged, the payment function corresponding to the target hotspot information is started at the moment, automatic payment preparation is achieved, the user does not need to manually select the required payment function before paying, the payment process is rapidly completed, and the payment efficiency is improved.

In another embodiment, the terminal device may be used for NFC payment, and in the card simulation mode of the NFC module, one or more radio frequency cards (hereinafter, referred to as simulation cards for convenience of description) may be simulated by the NFC module to support different payment modes, for example, the terminal device may simulate a plurality of bus cards to support different bus payment modes and simulate a plurality of bank cards to support different bank payment modes by the NFC module. And the terminal equipment can interact with the reading equipment supporting the NFC payment based on the analog card to complete the payment.

It should be noted that there are three main forms for the terminal device to implement NFC Card simulation, one is based on a Secure Module (SE), where the Secure Module is used to securely store sensitive information and provide a Secure execution environment for transaction, and may be integrated in a processor of the terminal device, or a Subscriber Identity Module (SIM) Card, or a Secure Digital Memory Card (SD) of the terminal device, or may be an independent chip, or the like; secondly, based on Host Card Emulation (HCE), various cards can be emulated by using app (application) application program on the Host to realize the Host Card Emulation function; and thirdly, a Universal Integrated Circuit Card (UICC) based. The NFC module stores routing information, the routing information comprises a routing position corresponding to the card simulation based on at least one form, and after receiving the AID instruction, the NFC module can send the AID instruction to the corresponding routing position based on the routing information, so that the module at the routing position executes the operation corresponding to the instruction.

As an embodiment, the security module may also be replaced by an Embedded security module (eSE), where the eSE is more Secure than the SE, and the hardware security level of the eSE is higher than EAL6 +. Therefore, the terminal equipment adopts the eSE, so that the payment security of the terminal equipment is higher. Specifically, the eSE may be installed with various types of card simulation applications, and when receiving the AID instruction sent by the NFC module, the eSE may start a corresponding card simulation application (APPLet) and activate a simulation card in the card simulation application to perform payment.

Referring to fig. 3, an interaction diagram of data interaction between a card emulation and a reading device based on two forms of an eSE and an HCE according to an embodiment of the present application is shown, as shown in fig. 3, a terminal device includes an NFC module, a security module, and a Host processor (Host CPU), optionally, the security module may be an eSE, the Host processor is configured to implement the card emulation based on the HCE form, a card emulation application runs on the security module and the Host processor, the reading device supports an NFC function, and can send an AID instruction to the terminal device, the terminal device can obtain the AID instruction based on the NFC module, and route the AID instruction into the security module or the Host processor, so as to start a function of the card emulation application in the security module or the Host processor, for example, start a payment function of a payment application in the security module.

In one example, the terminal device includes an NFC module and a security module, such as including an NFC module and an eSE, the eSE having installed thereon a card simulation application for transit payment, such as a transit payment application. For example, the terminal device detects that the target hotspot information matched with the preset hotspot information includes an SSID (service set identifier), such as BUS-freeWiFi, it can be considered that the user is currently in a BUS scene and may need to take a BUS, then the position information of the terminal device is acquired, and when the position information meets a preset effective condition, it can be considered that the user needs to pay by taking the BUS, at this time, a default route of the NFC module can be switched to the eSE, and the eSE is controlled to start a BUS payment application to realize a BUS payment function, and a BUS card in the BUS payment application is activated to activate a BUS payment mode, such as activating a deep kinjen can activate a deep kinjen payment mode, so that the BUS payment function based on the BUS payment mode is started, and when the terminal device approaches the reading device, payment can be performed based on the deep kinjen payment mode of the BUS payment function. Because the user is often required to judge the analog card to be selected according to a specific scene when NFC payment is used at present, the operation steps performed in the terminal equipment in the process are complex, the interaction capacity between the terminal equipment and the user is reduced, and the payment efficiency is low, therefore, the scene of the user is judged through hotspot information, whether the user needs to pay is judged by combining the position information of the terminal equipment, and when the position information meets the preset effective condition, the user needs to start the payment function under the scene, at the moment, the eSE is controlled to start the payment function corresponding to the target hotspot information, so that the default route switching is completed and the payment function corresponding to the target hotspot information is started before the user pays, the payment mode corresponding to the target hotspot information is activated, the safe automatic 'card-selecting' payment is realized, and the required payment function does not need to be manually selected before the user pays, therefore, the payment process is completed quickly, and the payment efficiency is improved.

In other examples, the terminal device may not include the security module, and the payment function is initiated based on the HCE or the HICC, and when the reading device supports the HCE or the UICC, the method provided in the embodiment of the present application may still be applied.

Compared with the prior art that the user needs to judge the card to be selected according to a specific scene, the operation steps performed in the mobile device in the process are very complicated, the intelligent interaction capacity between the mobile device and the user is seriously reduced, and the payment efficiency is low.

In addition, because public transportation systems of different cities or provinces are independent, when hotspot information of a public transportation category is detected and hotspot information of a non-public transportation category is detected, a difference exists when the terminal device starts a payment function corresponding to target hotspot information, specifically, referring to fig. 4, a terminal payment method provided by the embodiment of the present application is shown, and the method includes: s401 to S407.

S401: and detecting hotspot information.

S402: and when target hotspot information matched with the preset hotspot information is detected, determining the position information of the terminal equipment according to the target hotspot information.

In an embodiment, when target hotspot information matched with preset hotspot information is detected, determining a specific embodiment of location information of a terminal device according to the target hotspot information may include: when target hotspot information matched with preset hotspot information is detected, acquiring the signal intensity of the target hotspot information; and determining the position information of the terminal equipment according to the signal intensity.

In one example, when the terminal device detects the target hotspot information, the terminal device may obtain a signal strength corresponding to the target hotspot information, and according to the strength of the signal strength, the distance from the terminal device to the target hotspot, that is, the relative distance between the terminal device and the target hotspot may be determined, and the relative distance is used as the location information of the terminal device. In one example, a mapping relationship between the signal strength and the relative distance may be stored in advance, and according to the signal strength, the relative distance corresponding to the signal strength may be determined, so as to determine the location information of the terminal device. Therefore, the terminal equipment can still obtain the position information of the terminal equipment without starting positioning or having a positioning function, and is used for judging whether to start the payment function, so that the power consumption can be reduced, and the calculation complexity and the calculation efficiency can be improved because the distance between the equipment position and the hot spot position does not need to be calculated.

In another embodiment, when target hotspot information matched with preset hotspot information is detected, the specific embodiment of determining the location information of the terminal device according to the target hotspot information may include: when target hotspot information matched with preset hotspot information is detected, acquiring a hotspot position of the target hotspot information; and determining the position information of the terminal equipment according to the hot spot position.

In one example, the terminal device may obtain a hotspot location of the target hotspot information according to the MAC address of the target hotspot information based on GSM, where the hotspot location is a geographic location of a target hotspot corresponding to the target hotspot information. The terminal equipment acquires the current geographic position as the position information of the terminal equipment, and can acquire the absolute distance between the target hotspot and the terminal equipment according to the hotspot position and the position information of the terminal equipment, and the absolute distance is used as the position information of the terminal equipment. Therefore, the absolute distance between the target hotspot and the terminal equipment is used as the position information of the terminal equipment, so that the judgment accuracy of whether the position information meets the preset effective condition can be improved, and the accuracy of starting the payment function corresponding to the target hotspot information is also improved.

Further, in some embodiments, when target hotspot information matched with preset hotspot information is detected, determining a specific embodiment of the location information of the terminal device according to the target hotspot information may include: judging whether the position of the hot spot is kept unchanged within a first preset duration; and if the position of the hot spot is kept unchanged within the first preset duration, determining the position information of the terminal equipment according to the position of the hot spot.

In one example, if the hotspot location does not remain unchanged for the first preset duration, the subsequent steps may not be executed, and the hotspot information may be continuously detected, so that the payment function corresponding to the target hotspot information may not be started when the hotspot location is continuously changed. Taking a bus scene as an example, when a user does not need to take a bus and acts on the road, the terminal device may detect hot spot information of the bus which is running on the road, and at the moment, the bus may only pass through without stopping to carry passengers, so that the position information of the terminal device is determined by judging whether the position of the hot spot is kept unchanged within a first preset duration time and when the position of the hot spot is kept unchanged. Optionally, when the position of the hot spot is continuously changed, that is, only the passing bus is detected, and the bus stop is not detected, the subsequent steps are not executed, so that the false triggering probability can be reduced, the power consumption of equipment is saved, and the system availability is improved.

S403: and when the position information meets the preset effective condition, acquiring the category corresponding to the target hotspot information.

In some embodiments, when the location information satisfies the preset effective condition, the specific implementation of obtaining the category corresponding to the target hotspot information includes: judging whether the position information meets a preset effective condition or not; and if the position information meets the preset effective condition, acquiring the category corresponding to the target hotspot information. In some embodiments, if the location information does not satisfy the predetermined valid condition, the detection of the hotspot information may be performed in return, thereby saving power consumption.

The category is used to characterize a scene category corresponding to the hotspot information, and may be a category identifier used to characterize the scene category. The terminal equipment can determine the category corresponding to the category identification by acquiring the category identification of the target hotspot information, so as to acquire the category corresponding to the target hotspot information.

In one embodiment, the hotspot information includes an SSID, and the category corresponding to the target hotspot information can be acquired according to the SSID of the target hotspot information. For example, according to the fact that the SSID of the target hotspot information is BUS-freeWiFi, the category corresponding to the target hotspot information is determined to be a public traffic category according to the BUS of the BUS represented in the SSID. For another example, the SSID of the target hotspot information is Bank-WiFi, and the category corresponding to the target hotspot information can be determined to be the Bank category according to the "Bank" that represents the Bank in the SSID.

In some embodiments, the terminal device may further obtain a sub-category of the target hotspot information according to the SSID of the target hotspot information, for example, the bank category further includes a sub-category corresponding to each big bank, and when the terminal device queries whether the SSID has an identifier corresponding to the identifier of the sub-category, the sub-category of the target hotspot information, that is, a bank specifically corresponding to the sub-category, may be determined.

In another embodiment, the category is stored in a preset database, specifically, at least one preset hotspot message and a category corresponding to each preset hotspot message are stored in the preset database in advance, and when the terminal device searches for target hotspot messages matched with the preset hotspot messages based on the preset database, the category corresponding to the matched preset hotspot messages can be acquired as the category corresponding to the target hotspot messages.

S404: and judging whether the category is a public transportation category.

The category may be a category identifier for characterizing a category of the scene, and whether the category is a public transportation category may be determined based on whether the category identifier matches a category identifier of the public transportation category,

in an embodiment, the terminal device obtains the category corresponding to the target hotspot information according to the SSID of the target hotspot information, and at this time, as one mode, it may directly determine whether the category is a public transportation category based on the SSID, and determine whether the category is a public transportation category according to whether the SSID of the target hotspot information matches the public transportation category. And judging whether the SSID has characters or character strings related to the public traffic category to judge whether the category is the public traffic category. For example, a character or a character string corresponding to a public transportation category, such as "bus" indicating a bus, "or" subway "indicating a subway, is stored in advance, and it is determined whether the previously stored character or character string exists in the SSID. As another mode, the type of the acquired target hotspot information can be judged,

in another embodiment, the terminal device obtains the category corresponding to the target hotspot information based on the preset database, and at this time, whether the category is a public transportation category or not can be judged according to the category of the target hotspot information. Whether the category of the target hotspot information is consistent with the public transportation category or not can be judged, and when the category is consistent with the public transportation category, the category can be judged to be the public transportation category, and when the category is not consistent with the public transportation category, the category can be judged not to be the public transportation category.

In this embodiment, after determining whether the category is a public transportation category, the method may start a payment function corresponding to the category according to a determination result, and specifically may include:

if the category is the public transportation category, step S405 may be executed;

if the category is not the public transportation category, step S407 can be executed.

S405: and acquiring the hotspot attribute of the target hotspot information.

And if the category is the public transport category, acquiring the hotspot attribute of the target hotspot information. The hotspot attribute can be used for determining an effective use area of the target hotspot corresponding to the target hotspot information, and the effective use area can correspond to different cities or provinces. In one example, the transit systems of different cities or provinces are independent, and the transit cards which can support payment in different cities or provinces cannot be used universally, for example, Shenzhen can use Shenzhen to pay for taking a transit, but cannot use Shencheng to pay, so that the effective use region corresponding to the target hotspot information can be obtained by obtaining the hotspot attribute of the target hotspot information.

As an embodiment, the SSID of the hotspot information may include a character or a character string that characterizes the valid usage region, and at this time, the hotspot attribute of the target hotspot information may be determined according to the SSID of the target hotspot information, for example, the SSID is SZBUS-WiFi, and according to the SSID, the valid usage region where the target hotspot information can be obtained by "SZ" is Shenzhen, and the valid usage region is used as the hotspot attribute.

As another embodiment, the preset database stores hotspot attributes corresponding to the preset hotspot information, and the terminal device may obtain, based on the preset database, hotspot attributes corresponding to the preset hotspot information corresponding to the target hotspot information, and add the hotspot attributes as the hotspot attributes of the target hotspot information.

As another implementation manner, the terminal device may obtain a geographic location of the target hotspot information, obtain an area corresponding to the geographic location as an effective use area, and use the effective use area as a hotspot attribute of the target hotspot information. Therefore, an effective use region is determined according to the actual geographic position of the target hotspot information, for example, the target hotspot information includes a MAC address and an SSID of the target hotspot, such as SZBUS-WiFi, the terminal device can obtain the geographic position of the target hotspot corresponding to the target hotspot information based on GSM according to the MAC address of the target hotspot information, and use the geographic position as the geographic position of the target hotspot information, for example, the geographic position corresponds to a longitude and latitude coordinate located in shenzhen south mountain, the region corresponding to the geographic position can be obtained as shenzhen, and the shenzhen is used as the effective use region. Optionally, the area corresponding to the geographic location is obtained, the area can be determined according to the existing city or province of the public transportation system, the matching is performed according to the geographic location and the public transportation system, the matched city or province is used as the area of the geographic location, and the area is used as an effective use area, namely the hotspot attribute of the target hotspot information.

S406: and starting a payment function corresponding to the category according to the hotspot attribute.

And when the category is the public transportation category, the payment function corresponding to the category is the payment function corresponding to the public transportation category and is marked as the public payment function. The public payment function comprises one or more public payment modes, different public payment modes can correspond to different simulation cards and different hotspot attributes, for example, the public payment mode can comprise but is not limited to a Shenzhen payment mode based on Shenzhen payment, and the corresponding hotspot attribute is Shenzhen; the corresponding hotspot attribute of the Yangchengtong payment mode based on the Yangchengton payment is Guangzhou.

In an example, the specific implementation of the terminal device starting the payment function corresponding to the category according to the hotspot attribute may include: and determining a bus payment mode corresponding to the hotspot attribute according to the hotspot attribute, and starting a bus payment function based on the bus payment mode so as to automatically select a simulation card corresponding to the bus payment mode to wait for executing payment. For example, if the hotspot attribute of the target hotspot information corresponds to Shenzhen, it can be determined that the bus payment mode corresponding to Shenzhen is a Shenzhen bus payment mode, and the bus payment function is started based on the Shenzhen bus payment mode, so that when the category of the target hotspot information is a public traffic category, the payment function corresponding to the category is started in combination with the hotspot attribute and the category of the target hotspot information, and the supported payment mode can be accurately selected in a bus scene, and the payment mode does not need to be switched by a user through manual operation, so that automatic and accurate selection is realized, a payment process is quickly completed, and user experience of the terminal device in the bus scene is improved.

In another example, the hotspot attribute includes a geographic location of the target hotspot information, and the specific implementation manner of starting the payment function corresponding to the category according to the hotspot attribute is as follows: and starting a payment function corresponding to the category according to the geographic position. For example, the geographic position corresponds to a longitude and latitude coordinate located in the Shenzhen nan mountain, the region corresponding to the geographic position can be obtained as the Shenzhen, the Shenzhen is used as an effective use region, and the bus payment function is started based on the Shenzhen corresponding to the Shenzhen bus payment mode. Therefore, the terminal equipment can directly determine the bus payment mode under the bus payment function according to the position of the target hotspot information, and can automatically switch different bus payment modes under the bus payment function according to the position change of the target hotspot information, for example, a user arrives at Guangzhou from Shenzhen, when the hotspot information of Guangzhou is detected, and when the position information meets preset effective conditions, the bus payment function can be started based on the Yangchun bus payment mode, so that the user does not need manual operation, namely, when the Guangzhou needs to take the bus, the bus payment function corresponding to the Yangchun bus can be automatically started, the convenience and the efficiency of user terminal payment are greatly improved, and the terminal payment experience is improved.

S407: and starting a payment function corresponding to the category.

And if the category is not the public transport category, starting a payment function corresponding to the category. In one example, when the category of the target hotspot information is not a public transportation category, a payment function corresponding to the category is started, which is different from the particularity of a public transportation scene, and when other scenes are used, the payment function corresponding to the category can be started without acquiring the hotspot attribute of the target hotspot information. For example, if the SSID of the target hotspot information is CCB-WiFi, the type of the SSID is a bank type, and the SSID is not a public transportation type, the payment function corresponding to the bank type may be started, and the payment function is recorded as a bank payment function.

In some embodiments, the bank payment function includes one or more payment modes, denoted as bank payment modes, with different bank payment modes corresponding to different banks or bank cards.

It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.

The terminal payment method provided by this embodiment considers that public transportation systems of different cities or provinces are independent, so when hot spot information of a public transportation category is detected and when hot spot information of a non-public transportation category is detected, a difference exists when a terminal device starts a payment function corresponding to target hot spot information, so when the position information meets a preset effective condition, a category corresponding to the target hot spot information is obtained to determine a payment function to be started, whether the category is the public transportation category is judged, and when the category is the public transportation category, a payment mode under the payment function to be started is determined based on a hot spot attribute representing an effective use area of the target hot spot, and the payment function corresponding to the public transportation category is started, so that automatic 'card-selecting' payment in public transportation payment is realized without manual operation of a user, and when the category is not the public transportation category, the corresponding payment function is directly started according to the category. Therefore, various scenes are supported, and the terminal payment experience is further optimized.

Referring to fig. 5, a terminal payment method provided in the embodiment of the present application is shown, where the method includes: s501 to S504.

And judging whether the position information is in a preset position range, wherein the preset position range is used for judging whether the terminal device is close enough to a target hotspot corresponding to the target hotspot information, and for example, the preset position range may be within 30 meters from the target hotspot. If the position information is within the preset position range, the distance between the terminal device and the target hotspot is short, and if the position information is not within the preset position range, the distance between the terminal device and the target hotspot is long. And when the position information is within the preset position range, starting a payment function corresponding to the target hotspot information. When the terminal equipment is far away from the target hotspot, the probability that the user needs to execute the payment function corresponding to the target hotspot information is low, so that the false triggering probability can be effectively reduced, the accuracy rate of starting the function switching of the payment function is improved, frequent switching is avoided, and the power consumption can be reduced.

In this embodiment, after determining whether the position information is within the preset position range, the method further includes:

In the terminal payment method provided by this embodiment, on the basis of the foregoing embodiment, when determining whether the position information meets the preset effective condition, by first determining whether the position information is within the preset position range, and when the position information is within the preset position range, starting the payment function corresponding to the target hotspot information, because the probability that the user will execute the payment function corresponding to the target hotspot information is low when the terminal device is far away from the target hotspot, it is determined whether to start the payment function corresponding to the target hotspot information by determining whether the position information is within the preset position range, so that the false trigger probability can be effectively reduced, the accuracy of starting the payment function and performing the function switching can be improved, frequent switching can be avoided, and power consumption can be reduced.

In addition, in some embodiments, when determining whether the position information meets the preset effective condition, the hotspot position may be determined first before the position information of the terminal device is obtained, and when the hotspot position is not changed, it is determined whether the position information of the terminal device is within the preset position range, so as to avoid power consumption caused by executing subsequent steps when the bus only passes but does not stop, and further improve system availability. Referring to fig. 6, a terminal payment method provided in the embodiment of the present application is shown, specifically, the method includes: s601 to S606.

S601: and detecting hotspot information.

S602: and when target hotspot information matched with the preset hotspot information is detected, determining the position information of the terminal equipment according to the target hotspot information.

S603: and acquiring the hotspot position of the target hotspot information.

In some embodiments, the hotspot location of the target hotspot information may be obtained based on the GSM provided by *** according to the MAC address of the target hotspot information.

S604: and judging whether the position of the hot spot is kept unchanged within a first preset duration.

In this embodiment, after determining whether the hotspot location remains unchanged within the first preset duration, the method further includes:

if the hotspot position remains unchanged within the first preset duration, step S605 may be executed;

if the hotspot position does not remain unchanged within the first preset duration, the method may return to step S601 to continue to detect the hotspot information.

S606: and starting a payment function corresponding to the target hotspot information.

In addition, in some embodiments, when determining whether the location information meets the preset effective condition, the location information of the terminal device may be obtained first, and if the location information is within the preset location range, the time that the terminal device stays within the preset location range may be obtained again, and the payment function corresponding to the target hotspot information is started only when the terminal device stays overtime, so that the accuracy of determining the payment intention of the user may be improved, and false triggering caused by the fact that the payment function corresponding to the target hotspot information is still started when the user only passes through a bus station and has no intention of buses such as a bus station may be avoided, thereby avoiding unnecessary power consumption and improving usability. Specifically, please refer to fig. 7, which illustrates a terminal payment method provided in the embodiment of the present application, where the method includes: s701 to S706.

S701: and detecting hotspot information.

S702: and when target hotspot information matched with the preset hotspot information is detected, determining the position information of the terminal equipment according to the target hotspot information.

S703: and judging whether the position information is in a preset position range.

if the position information is within the preset position range, step S704 may be executed;

if the position information is not within the preset position range, the step S701 may be executed again to continue to detect the hotspot information.

S704: and acquiring the duration of the position information within the preset position range as the stay time.

And if the position information is in the preset position range, acquiring the duration time of the position information in the preset position range as the stay time. The length of the stay time can represent the length of the stay time of the user in the preset position range. For example, in a bus scene, if the terminal device detects hotspot information of a bus and the terminal device is located in a preset position range, the terminal device may be considered to be near the bus, and the longer the terminal device stays in the preset position range, the longer the user stays near the bus.

The terminal device may acquire the geographical position of the terminal device itself as the position information based on a positioning module such as a GPS module. As an implementation manner, the terminal device may obtain the position information of the terminal device in real time, and after determining whether the position information is within the preset position range, determine that the position information is within the preset position range at a first time, and accumulate the duration time, that is, the accumulated staying time, until the time when the position information is not within the preset position range is monitored, end the accumulation, and obtain the staying time of the accumulation.

As another embodiment, the terminal device may further obtain the location information at intervals according to a specified time interval, determine whether the location information obtained each time is within a preset location range, obtain a second time when the location information is not within the preset location range, and further obtain a duration between the first time and the second time as the retention time.

Further, in some embodiments, if the staying time exceeds the preset time threshold, the accumulation may be ended in advance, and the subsequent steps may be executed.

S705: and judging whether the retention time exceeds a preset time threshold value.

The preset time threshold may be preset by a program or may be user-defined. Alternatively, the preset time threshold may be 1 minute, 5 minutes, etc., and is not limited herein. When the staying time exceeds the preset time threshold, the payment function corresponding to the target hotspot information is started, so that it can be understood that the longer the preset time threshold is, the more cautious the judgment of starting the payment function corresponding to the target hotspot information is, and the higher the accuracy of judging whether the user has the payment intention is. In addition, with the reduction of the preset time threshold, the judgment rate of the payment intention can be ensured, and the judgment efficiency is improved, so that the payment function corresponding to the target hotspot information can be started more quickly when the payment function is required to be started.

In this embodiment, after determining whether the staying time exceeds the preset time threshold, the method further includes:

if the staying time exceeds the preset time threshold, step S706 may be executed;

if the staying time does not exceed the preset time threshold, the step S701 may be executed again to continue to detect the hotspot information.

S706: and if the retention time exceeds a preset time threshold, starting a payment function corresponding to the target hotspot information.

If the stay time in the preset position range exceeds the preset time threshold, the user can be considered to wait for the bus and have a strong intention of bus payment, and at the moment, the payment function corresponding to the target hotspot information is started, so that the accuracy rate of judging the payment intention of the user can be improved, the false triggering caused by starting the payment function corresponding to the target hotspot information when the user only passes through the bus station and has no intention of waiting at the bus station and the like can be avoided, unnecessary power consumption is avoided, and the usability is improved.

In addition, in some embodiments, when determining whether the location information meets a preset effective condition, the location information of the terminal device may be obtained first, if the location information is within a preset location range, the hotspot location of the target hotspot information may be obtained again, and when the hotspot location is still, the staying time of the terminal device within the preset location range is obtained again, and when the staying time is overtime, the payment function corresponding to the target hotspot information is started. Therefore, whether the hot spot position of the target hot spot information is kept unchanged within the specified duration is determined before whether the user stays overtime is judged, and the stay time is obtained to judge whether the user stays overtime when the stay time is not changed, so that the false triggering caused by starting the payment function under the condition that the user only passes through a bus station and the bus only passes through the user but does not stop can be avoided, the judgment accuracy of the payment intention of the user is further improved, the starting accuracy is improved, and the system availability is further improved. Specifically, please refer to fig. 8, which illustrates a terminal payment method provided in the embodiment of the present application, where the method includes: s801 to S808.

Therefore, when the target hotspot information matched with the preset hotspot information is detected, false triggering caused by the fact that the user starts the payment function corresponding to the target hotspot information only passing by the vicinity of the target hotspot can be avoided, power consumption caused by frequent starting is reduced, and system availability is improved.

Therefore, the absolute distance between the terminal equipment and the target hotspot does not need to be calculated, the calculation complexity is reduced, and the calculation efficiency is improved. Specifically, please refer to fig. 10, which illustrates a terminal payment method provided in the embodiment of the present application, where the method includes: s1001 to S1005.

S1001: and detecting hotspot information.

S1002: and when target hotspot information matched with the preset hotspot information is detected, acquiring the signal intensity of the target hotspot information.

When the WLAN module is in an open state, the terminal equipment can acquire the signal intensity of the target hotspot information.

S1003: and determining the position information of the terminal equipment according to the signal intensity.

The mapping relation between the signal intensity and the distance value is stored in advance, the distance value corresponding to the signal intensity can be determined according to the signal intensity, and the distance value is used as the position information of the terminal equipment. And the distance value corresponding to the signal intensity represents the relative distance between the terminal equipment and the target hotspot.

The preset signal strength can be preset by a program or customized by a user, and the preset signal strength can be used for determining a scale for judging a scene or a payment intention of the user. After the signal intensity exceeds the preset signal intensity, the payment function corresponding to the target hotspot information is started, so that on one hand, the higher the preset signal intensity is, the closer the terminal device is to the target hotspot, and the accuracy of judging the payment intention of the user can be improved; on the other hand, the lower the preset signal intensity is, the farther the terminal device is from the target hotspot, and the judgment efficiency can be accelerated.

As an embodiment, the preset signal strength may be determined according to a distance value corresponding to a preset position range, so that whether the position information is within the preset position range may be determined by determining whether the signal strength exceeds the preset signal strength. For example, the preset location range is within 10 meters from the target hotspot, and the corresponding distance value is 10 meters, and the preset signal strength may be a detectable signal strength of the terminal device at a distance of 10 meters from the target hotspot, such as-60 dbm.

In this embodiment, after determining whether the signal strength exceeds the predetermined signal strength, the method further includes:

if the signal strength exceeds the predetermined signal strength, step S1005 may be executed;

if the signal strength does not exceed the predetermined signal strength, the method may return to step S1001 to continue detecting the hotspot information.
