Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the The embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the implementation in this application, all other implementations obtained by a person of ordinary skill in the art without creative labor should fall within the protection scope of this application.

The embodiment of the present application provides a payment method, and the payment method can be applied to a system architecture of a client and a payment terminal. The payment terminal may be a payment receiving device having a Bluetooth communication function. During Bluetooth communication with the client, the payment terminal is usually in slave mode and can send out signals in the Bluetooth frequency band. Specifically, the payment terminal may be, for example, a point-of-sale (POS) machine, a bus toll machine, or a campus toll machine with a Bluetooth communication function, or a payment device running on the payment device. Collection support software. The number of the payment terminals is not specifically limited in this embodiment. The payment terminal may be one payment terminal, or may be several payment terminals, or a payment terminal cluster formed by several payment terminals.

In this embodiment, the client may be an electronic device for mobile payment and having a Bluetooth communication function. When performing Bluetooth communication with a payment terminal, the client is usually in a master mode and can obtain signal intensity distribution data corresponding to the signal. Specifically, the client may be, for example, a tablet computer, a notebook computer, a smart phone, a digital assistant, a smart wearable device, and the like. Alternatively, the client may be software capable of running in the electronic device. Specifically, the client may be a mobile application in an electronic device, and the mobile application may be, for example, WeChat, PayPal, or the like.

The embodiment of the present application provides a method for information interaction, and the method for information interaction can be applied to the above-mentioned client. The method may be provided with initial transmission threshold values and initial signal strength distribution data corresponding to when the payment terminal transmits payment data.

In this embodiment, the initial transmission threshold may be a signal strength indication (Received Signal Strength Indication, RSSI) value. The initial transmission threshold may be a transmission threshold corresponding to the first time that the client and the payment terminal transmit payment data, that is, the transmission threshold initially set. Generally, the initially set transmission threshold may be a small value, for example, -100 milliwatts decibel (dbm), to ensure that different clients, such as different smart phones, can trigger the payment terminal. Payment data transfer function.

Not only that, the initial transmission threshold may also be a transmission threshold corresponding to a time when the payment terminal performs payment data transmission after the client and the payment terminal perform payment data transmission for the first time.

In this embodiment, the initial signal strength distribution data may be a type of RSSI distribution data. The RSSI distribution data may be an RSSI value corresponding to a Bluetooth signal sent by the payment terminal and acquired by the client within a specified time period. In this way, the RSSI distribution data may include frequencies corresponding to different RSSI values.

In this embodiment, the initial signal strength distribution data may be signal strength distribution data obtained when the client and the payment terminal transmit payment data for the first time, or may be the first payment data performed by the client and the payment terminal. After transmission, the signal intensity distribution data obtained when the payment data is transmitted with the payment terminal at one time.

In this embodiment, if the initial signal strength distribution data satisfies a condition associated with the initial transmission threshold, the client may perform payment data transmission with the payment terminal. Specifically, the conditions associated with the initial transmission threshold may include that an average value of signal strength in the initial signal strength distribution data is greater than or equal to the initial transmission threshold.

In this embodiment, each time the client performs payment data transmission with the payment terminal, the client may record the transmission threshold value and signal strength distribution data corresponding to the current payment data transmission with the payment terminal to update the data with the payment terminal. The target transmission threshold corresponding to the next time the payment terminal transmits payment data.

Referring to FIG. 3, the method may include the following steps.

S11: Determine a target transmission threshold according to the initial transmission threshold and the initial signal strength distribution data.

In this embodiment, the client may determine the target transmission threshold according to the initial transmission threshold value and the initial signal strength distribution data corresponding to when the payment terminal transmitted the last payment data, as a second time with the payment terminal. Judgment basis for payment data transmission. Specifically, the client may determine based on the specified number of times of payment data transmission before the payment terminal, the specified parameter associated with the number of times of payment data transmission, and the maximum signal strength in the initial signal strength distribution data. A weighting coefficient such that the signal with the largest proportion in the signal strength distribution data corresponding to the specified distance is determined according to the weighting coefficient, the maximum signal strength in the signal strength distribution data, and the target transmission threshold determined by the initial transmission threshold The absolute value of the difference between the intensity values is less than or equal to the specified intensity value. The specified distance may be a distance between the client and the payment terminal during payment data transmission, and the distance may be set according to an actual application scenario. For example, when a user makes a payment on a bus through a smart phone, the distance between the smart phone and the tolling device on the bus can usually be 5-10 cm. Alternatively, when a user makes a payment through the smart phone in the school cafeteria, the distance between the smart phone and the charging device of the cafeteria window is usually 10-15 cm. The specified intensity value may be zero or a smaller value approaching zero. In this way, when the distance between the client terminal used by the user and the payment terminal is close to the specified distance, the probability that the signal strength in the obtained signal strength distribution data is greater than the target transmission threshold is greater, so that the client can be Quickly connect with the payment terminal and perform payment data transmission, so that the payment speed can be improved.

Not only this, but also on the basis of the above-mentioned implementation manner of determining the target transmission threshold, an average value of the signal strength in the initial signal strength distribution data may be considered. Specifically, the client may also be based on the number of times of payment data transmission before the payment terminal, the specified parameter associated with the number of times of payment data transmission, and the average value of the signal strength in the initial signal strength distribution data and A maximum signal strength, and a weight coefficient is determined such that a target transmission threshold determined from the weight coefficient, the average signal strength and the maximum signal strength in the signal intensity distribution data, and the target transmission threshold determined by the initial transmission threshold is at a specified distance The absolute value of the difference between the largest signal intensity values in the corresponding signal intensity distribution data is less than or equal to the specified intensity value.

In this embodiment, when a value obtained by subtracting the initial transmission threshold value from the maximum value of the signal strength in the initial signal strength distribution data is greater than a specified difference, the initial transmission threshold value and the initial signal strength Distribute the data to determine the target transmission threshold. For example, when the value obtained by subtracting the initial transmission threshold from the maximum signal strength in the initial signal strength distribution data is greater than a specified difference, that is, VM _n -T _n > p, where VM _n represents The maximum signal strength in the initial signal strength distribution data corresponding to the payment terminal's nth payment data transmission, T _n represents the initial transmission threshold corresponding to the payment terminal's nth payment data transmission, and p represents the Specify the difference; the target transmission threshold T _{n + 1} can be determined using the following formula:

T _{n + 1} = α (VM _n -q) + (1-α) T _n

Among them, α represents the weight coefficient, and b represents a specified parameter associated with the number n of payment data transmissions. For example, when the number n of payment data transmissions is less than or equal to 2, b is 2, and when n is greater than 2 , B is 5; q and

Each is a parameter associated with the specified difference. For example, when the specified difference is 20dbm, q and

Can be 15 and 18 respectively.

When the value obtained by subtracting the initial transmission threshold value from the maximum value of the signal strength in the initial signal strength distribution data is less than or equal to the specified difference value, use the initial transmission threshold value as the target transmission threshold value, that is, not in Update the transmission threshold. In practical applications, the value range of the specified difference may be generally 15 to 20 dbm.

S13: Acquire current signal intensity distribution data, and determine whether the current signal intensity distribution data meets a condition associated with the target transmission threshold; if it is satisfied, perform payment data transmission with the payment terminal again.

In this embodiment, before the client needs to perform payment data transmission with the payment terminal again, it may first obtain the current signal intensity distribution data and determine whether the current signal intensity distribution data meets the target transmission threshold association. conditions of. If it is satisfied, payment data transmission can be performed with the payment terminal again. The conditions for the target transmission threshold association may specifically include: an average value of signal strength in the current signal intensity distribution data is greater than or equal to the target transmission threshold. In this way, if the average value of the signal strength in the current signal strength distribution data is greater than or equal to the target transmission threshold, the client can perform payment data transmission with the payment terminal again.

In a specific application scenario, the client is a smart phone, and the payment terminal is a cash receiving device on a bus. The cash receiving device is connected to the smartphone and the payment data is transmitted via Bluetooth. The machine is in a slave mode and broadcasts signals of different frequency bands. The smart phone scans the signals and obtains signal intensity distribution data corresponding to the signals. When the user took the bus last time, the user used the smartphone to transmit payment data to the payment device and completed the payment. At the same time, the smartphone recorded the initial transmission threshold and the initial signal corresponding to the payment data transmission with the payment device. The intensity distribution data, and according to the initial transmission threshold and the initial signal strength threshold, calculate a target transmission threshold corresponding to the next payment data transmission with the receiving machine. The user took the bus again, and prepared to pay the bus fare through the smartphone before getting on the bus. In the process of the user holding the smartphone near the cash register, the user can obtain the current signal strength data through the smartphone and determine the current signal strength. The average signal strength in the signal strength data is greater than or equal to the target transmission threshold. When the distance between the smartphone and the cash register reaches a specified distance, it is determined that the average signal strength in the current signal strength data is greater than the target transmission threshold. At this time, the smart phone can perform payment data transmission with the cash receiving device again. In this way, the transmission threshold value that is compatible with the smart phone can be automatically updated, so that at a normal payment distance, users can make normal payments using different smart phones, thereby improving the user's payment experience.

Not only that, for different payment machines, the smartphone can also automatically update the corresponding transmission threshold when transmitting payment data with different payment machines, so as to avoid different signal strengths from different payment machines. Caused compatibility issues.

In one embodiment of the present application, since the client and the payment terminal need to establish a connection before transmitting payment data, the connection usually takes 0.2 to 0.3 seconds. Therefore, in order to further improve the user's payment experience, the customer The terminal may also pre-connect with the payment terminal before transmitting payment data with the payment terminal. Specifically, before determining whether the current signal strength distribution data meets a condition of the target transmission threshold association, the method may further include the following steps.

S21: Determine a target pre-connection threshold according to the target transmission threshold; wherein the target pre-connection threshold is smaller than the target transmission threshold.

In this embodiment, determining the target pre-connection threshold according to the target transmission threshold may specifically include multiplying a first designated coefficient by a parameter associated with the target transmission threshold, and subtracting the target transmission threshold. The product result is obtained the target pre-connection threshold. The target pre-connection threshold is smaller than the target transmission threshold; the parameter associated with the target transmission threshold may be a logarithmic function associated with the target transmission threshold. For example, the following formula may be used to characterize the target pre-connection threshold P _{n + 1} :

P _{n + 1} = T _{n + 1} -c ₁ × C _{n + 1}

Wherein, c ₁ represents the first designated coefficient, and the specific value can be set according to the actual application situation. For example, the value of c ₁ can be 10; C _{n + 1} represents a parameter associated with the target transmission threshold. ; T _{n + 1} represents the target transmission threshold.

The following formula can be used to characterize the parameter C _{n + 1} associated with the target transmission threshold:

Among them, a ₁ and a ₂ are designated constants, and specific values can be set according to the actual application situation. For example, a ₁ and a ₂ can be 100 and 10, respectively.

S23: Determine whether the current signal strength distribution data meets a condition associated with the target pre-connection threshold; if it is satisfied, establish a connection with the payment terminal.

In this embodiment, after determining the target pre-connection threshold, the client can obtain the current signal strength distribution data and determine whether the current signal strength distribution data meets the conditions associated with the target pre-connection threshold, and if it meets, A connection is established with the payment terminal. The conditions related to the target pre-connection threshold may specifically include: an average value of signal strength in the current signal intensity distribution data is greater than or equal to the target pre-connection threshold. Because the target pre-connection threshold is less than the target transmission threshold, before a user uses a client to make a payment, that is, when the distance between the client and the payment terminal is greater than the specified distance, the client may first prepare to contact with The payment terminal is pre-connected. In this way, when the client approaches the payment terminal, the client can have enough time to establish a connection with the payment terminal, so that the distance between the client and the payment terminal When the specified distance is reached, a connection is established with the payment terminal, and at the same time, the current signal strength distribution data meets the conditions associated with the target transmission threshold, and the client can directly transmit payment data with the payment terminal without having to Waiting for a connection again can reduce payment time. For example, the specified distance is 10 centimeters, and when the distance between the client and the payment terminal is 10 centimeters, payment data can be transmitted with the payment terminal; the user holds the client, and keeps approaching the payment terminal, Prepare to make a payment. When the distance between the client and the payment terminal is 30 cm, the obtained signal intensity distribution data meets the conditions associated with the target pre-connection threshold, and may be ready to start pre-connection with the payment terminal. Continue to approach, when the distance between the client and the payment terminal is 10 cm, a connection with the payment terminal is established, and at the same time, the current signal strength distribution data meets the condition of the target transmission threshold association, then Directly perform payment data transmission with the payment terminal.

In an embodiment of the present application, in the case that the client establishes a connection with the payment terminal and does not perform data transmission with the payment terminal, in order to prevent the client from occupying the payment terminal due to the user's sudden departure Of connected resources. The method may further include the following steps.

S31: Determine a target disconnection threshold according to the target transmission threshold; wherein the target disconnection threshold is less than the target pre-connection threshold.

In this embodiment, determining the target disconnection threshold according to the target transmission threshold may specifically include multiplying a second designated coefficient by a parameter associated with the target transmission threshold, and subtracting the target transmission threshold from the target transmission threshold. The result of de-producting is to obtain the target pre-connection threshold. The target disconnection threshold is smaller than the target pre-connection threshold; the second specified coefficient is greater than the first specified coefficient. The parameter associated with the target transmission threshold may be a logarithmic function associated with the target transmission threshold. For example, the following formula can be used to characterize the target disconnection threshold D _{n + 1} :

D _{n + 1} = T _{n + 1} -c ₂ × C _{n + 1}

Among them, c ₂ represents the second designated coefficient, and the specific value can be set according to the actual application situation. For example, the value of c ₂ can be 20; C _{n + 1} represents a parameter associated with the target transmission threshold. ; T _{n + 1} represents the target transmission threshold.

S33: In a case where a connection is established with the payment terminal and no data transmission is performed with the payment terminal, determine whether the current signal strength distribution data meets a condition associated with the target disconnection threshold; if it is satisfied, and The payment terminal is disconnected.

In this embodiment, after determining the disconnection threshold, the client can obtain current signal strength distribution data. In the case where a connection is established with the payment terminal and no data transmission is performed with the payment terminal, the client can determine whether the current signal strength distribution data meets the conditions associated with the target disconnection threshold; if it meets, Disconnected from the payment terminal. Wherein, the condition associated with the target disconnection threshold may specifically include: an average value of signal strength in the current signal intensity distribution data is less than or equal to the target pre-connection threshold. In this way, in the case where a connection is established with the payment terminal and no data transmission is performed with the payment terminal, when the user suddenly leaves, the client is also far away from the payment terminal, resulting in the acquired current signal intensity distribution data. The average value of the signal strength is lower than the target pre-connection threshold. At this time, the client can disconnect from the payment terminal, so as to prevent the phenomenon of occupying connection resources with the payment terminal.

In an embodiment of the present application, in a case where the client establishes a connection with the payment terminal and does not perform payment data transmission with the payment terminal, the user is stalled because of being delayed by other things, causing the client to communicate with the payment terminal. The payment terminal establishes a connection for a long time, but cannot perform payment data transmission with the payment terminal, which will waste the connection resources of the payment terminal. To avoid this situation, the method may further include: in a case where a connection is established with the payment terminal and no data transmission is performed with the payment terminal, determining whether the duration of continuous connection with the payment terminal is greater than or equal to Specify a connection duration; if the duration of continuous connection with the payment terminal is greater than or equal to the specified connection duration, disconnect from the payment terminal. The specified connection duration may be set according to actual application conditions, which is not limited herein.

In an embodiment of the present application, in actual applications, because the signal broadcast by the payment terminal is affected by the actual scene, its propagation path has multipath refraction, which will cause the RSSI value in the signal intensity distribution data obtained by the client. It does not correspond to the distance completely, and even a large error occurs, that is, the phenomenon of jumping, which causes the trigger distance of near-field payment is not stable. For example, as shown in FIG. 4, in the signal strength distribution data obtained when a smart phone is at a specified distance from a payment terminal, jump phenomena occur near RSSI values of -62dbm and -53dbm, respectively. Among them, the abscissa and ordinate in FIG. 4 are the RSSI value and the ratio, respectively, and the units are milliwatt decibel (dbm) and thousandth ratio, respectively. In order to reduce the distance error caused by the jump phenomenon of RSSI value, obtaining the current signal intensity distribution data may include the following steps.

S41: Acquire a current signal intensity sampling point sequence. The signal intensity sampling point sequence includes a plurality of signal intensity sampling points.

In this embodiment, the client can acquire a signal intensity sampling point corresponding to a signal sent by the payment terminal according to a specified time interval. In this way, the client can acquire multiple signal intensity sampling points within the currently specified duration. After the signal intensity sampling points are arranged in chronological order, the current signal intensity sampling point sequence is formed. The value range of the specified time length may be 0.2 seconds to 0.3 seconds, and the value range of the specified time interval may be 0.01 to 0.05 seconds. Generally, the specified duration and the specified time interval can be set according to actual application conditions.

In this embodiment, the client may store a sequence of signal strength sampling points within a specified time period, and the sampling time corresponding to the signal strength sampling points in the sequence is farther than the specified time from the current time, and the client may delete the sequence. And obtain the current signal intensity sampling point sequence within the specified time period again.

S43: Divide the signal intensity sampling point sequence into at least one subsequence, and determine a median signal intensity of the subsequence.

In this embodiment, after acquiring the current signal intensity sampling point sequence, the signal intensity sampling point sequence may be divided into at least one subsequence according to a specified time window and window length, or according to the specified number of sampling points, The signal intensity sampling point sequence is divided into at least one subsequence. Among them, two adjacent subsequences have overlapping signal intensity sampling points. For example, as shown in FIG. 5, two adjacent subsequences A1 and A2, except for the first signal strength sampling point of subsequence A1 and the last signal strength sampling point of subsequence A2, are all other signal strength sampling points. The overlapping signal strength sampling points in the sequences A1 and A2, and the subsequence A2 is equivalent to the subsequence A1 moving a signal strength sampling point.

In this embodiment, after the sequence of signal intensity sampling points is divided into at least one subsequence, the median signal intensity of each subsequence may be determined, that is, the signal intensity of multiple signal intensity sampling points in each subsequence. Median.

S45: Determine the current signal strength distribution data according to a median signal strength of the subsequence.

In this embodiment, determining the current signal strength distribution data according to the median signal strength of the subsequence may specifically include that the median signal strength of the subsequence may be used as an intermediate in the subsequence. The signal strength value of the signal strength sampling point at the position, or the signal strength value of the signal strength sampling point at other specified positions in the subsequence. The median signal intensity of each subsequence is processed in the manner described above, so that the processed signal intensity sampling points can be obtained, and the signal intensity distribution data composed of the signal intensity values of the processed signal intensity samples is described as Current signal strength distribution data. For example, as shown in FIG. 6, when a smartphone is at a specified distance from a payment terminal, the jump phenomenon of RSSI value in the signal intensity distribution data obtained in the above manner within the specified time period is significantly reduced.

In an embodiment of the present application, after dividing the signal intensity sampling point sequence into at least one subsequence, an average value of the signal intensity of the subsequence may be determined, and according to the average value of the signal intensity of the subsequence, Determining the current signal strength distribution data. Alternatively, an average value of the signal strength of the sampling points of the signal strength in the subsequence may be determined, and the current signal strength distribution data may be determined according to the average value of the signal strength of the sampling points of the signal strength in the subsequence. Wherein, the partial signal strength sampling points may be signal strength sampling points in a middle portion of the subsequence, and the number of sampling points of the partial signal strength sampling points may be five percent of the number of sampling points of the subsequence. ten.

In an embodiment of the present application, in actual applications, the client itself may malfunction, causing the acquired signal strength value to always be a small value, even if the distance between the client and the payment terminal is very close. It may also be impossible to transmit payment data with the payment terminal, but in this case, the client will continue to update the transmission threshold, pre-connection threshold, and disconnection threshold, and the updated transmission threshold, pre-connection threshold, and disconnection The connection threshold is a small value, and continuous attempts to perform payment data transmission with the payment terminal will waste time and are not good for users to find problems. To avoid this situation, when at least one of the target transmission threshold, the target pre-connection threshold, and the target disconnection threshold is less than a specified threshold, for example, the specified threshold is -100 dbm, the client The threshold update and transmission conditions are not judged, and a prompt for a client payment failure is given.

In an embodiment of the present application, in actual applications, the client used by the user performs a normal payment data transmission with the payment terminal several times before putting a protective cover made of metal material on the client, and most of the client The area is all wrapped by the protective cover. In this case, due to the signal shielding effect of the protective cover, the signal strength obtained by the client again may be small. According to the last updated transmission threshold, it may be difficult to communicate with the The payment terminal transmits payment data again. To avoid this situation, the client can restore the transmission threshold to the initial transmission threshold corresponding to the first use to re-update the transmission threshold.

In the 1990s, for a technical improvement, it can be clearly distinguished whether it is an improvement in hardware (for example, the improvement of circuit structures such as diodes, transistors, switches, etc.) or an improvement in software (for the improvement of method flow). However, with the development of technology, the improvement of many methods and processes can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by hardware entity modules. For example, a programmable logic device (Programmable Logic Device (PLD)) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. It is programmed by the designer to "integrate" a digital system on a PLD, without the need for a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of making integrated circuit chips by hand, this programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used in program development and writing, but before compilation The original code must also be written in a specific programming language, which is called Hardware Description Language (HDL), and HDL is not only one, but there are many types, such as ABEL (Advanced Boolean ExpressionLanguage) , AHDL (Altera, Hardware, Description, Language), Confluence, CUPL (Cornell, University Programming, Language), HDCal, JHDL (Java, Hardware, Description, Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby, Hardware, Description), etc. It is VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog2. Those skilled in the art should also be clear that as long as the method flow is slightly logically programmed and integrated into the integrated circuit using the above-mentioned several hardware description languages, a hardware circuit that implements the logic method flow can be easily obtained.

Those skilled in the art also know that, in addition to implementing the client and server in a pure computer-readable program code manner, the method steps can be logically programmed to make the client and server use logic gates, switches, application specific integrated circuits, and programmable logic. Controller and embedded microcontroller to achieve the same function. Therefore, such a client and a server can be regarded as a kind of hardware component, and a device included therein for implementing various functions can also be regarded as a structure within the hardware component. Or even, the means for implementing various functions can be regarded as a structure that can be both a software module implementing the method and a hardware component.

It can be known from the description of the foregoing embodiments that those skilled in the art can clearly understand that this application can be implemented by means of software plus a necessary universal hardware platform. Based on such an understanding, the technical solution of the present application, in essence, or a part that contributes to the existing technology, can be embodied in the form of a software product, which can be stored in a storage medium, such as ROM / RAM, magnetic disk , Optical discs, etc., including a number of instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in various embodiments or portions of the embodiments of the present application.

Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the implementation of the computer storage medium, the server, and the client, all can be explained with reference to the introduction of the foregoing method implementation.

This application may be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments in which tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules may be located in local and remote computer storage media, including storage devices.

Although the present application has been described through embodiments, those skilled in the art know that there are many variations and changes in the present application without departing from the spirit of the present application, and it is expected that the appended claims include these variations and changes without departing from the spirit of the present application.
