Description

支付方法及用戶端Payment method and client

本申請關於互聯網技術領域，特別關於一種支付方法及用戶端。This application relates to the field of Internet technology, particularly to a payment method and a user terminal.

隨著互聯網技術的快速發展，行動支付的應用不斷增多。利用智慧手機（如Android手機、iOS手機等）、平板電腦以及行動上網裝置（Mobile Internet Devices，MID）、PAD等用戶端進行線上支付已成為一種便捷、流行的支付方式。 在實際應用中發現，在基於低功耗藍牙（Bluetooth Low Energy，BLE）近場支付的方法中，針對不同的用戶端，例如不同的智慧手機，即使分別與支付終端之間的距離相同，但接收到的信號強度指示（Received Signal Strength Indication，RSSI）卻可能存在差異。例如，如圖1和圖2所示，兩種分別為華為mate8和小米5s的智慧手機，在與支付終端相同距離下接受到的RSSI並不相同，其中，距離包括2厘米、5厘米、20厘米和50厘米；圖1和圖2中的橫坐標和縱坐標分別為RSSI值和占比，單位分別為毫瓦分貝（dbm）和千分比。這樣，可能導致用戶在使用某款智慧手機時，由於該智慧手機在通常支付距離處的RSSI小於設定的支付資料傳輸閾值，而無法進行正常支付，從而降低用戶的支付體驗。With the rapid development of Internet technology, the application of mobile payment continues to increase. Using smart phones (such as Android phones, iOS phones, etc.), tablet computers, mobile Internet devices (Mobile Internet Devices, MID), PAD and other user terminals for online payment has become a convenient and popular payment method. In practical applications, it is found that in the near-field payment method based on Bluetooth Low Energy (BLE), for different user terminals, such as different smart phones, even if the distance between each and the payment terminal is the same, The received signal strength indication (RSSI) may be different. For example, as shown in Figure 1 and Figure 2, two smartphones, namely Huawei mate 8 and Xiaomi 5s, receive different RSSIs at the same distance from the payment terminal. The distances include 2 cm, 5 cm, 20 Centimeters and 50 centimeters; the abscissa and ordinate in Fig. 1 and Fig. 2 are the RSSI value and the proportion, respectively, and the units are decibels (dbm) and thousandths per milliwatt. In this way, when a user uses a certain smart phone, because the RSSI of the smart phone at the normal payment distance is less than the set payment data transmission threshold, normal payment may not be performed, thereby reducing the user's payment experience.

和

分別可以為15和18。 當所述初始信號強度分佈資料中的信號強度最大值減去所述初始傳輸閾值後得到的值小於或等於所述指定差值時，將所述初始傳輸閾值作為所述目標傳輸閾值，即不在更新傳輸閾值。在實際應用中，所述指定差值的取值範圍通常可以為15~20 dbm。 S13：獲取當前的信號強度分佈資料，並判斷所述當前的信號強度分佈資料是否滿足所述目標傳輸閾值關聯的條件；若滿足，與所述支付終端再次進行支付資料傳輸。 在本實施方式中，在用戶端需要與所述支付終端再次進行支付資料傳輸之前，可以先獲取當前的信號強度分佈資料，並判斷所述當前的信號強度分佈資料是否滿足所述目標傳輸閾值關聯的條件。若滿足，便可以與所述支付終端再次進行支付資料傳輸。所述目標傳輸閾值關聯的條件，具體可以包括：所述當前的信號強度分佈資料中的信號強度平均值大於或等於所述目標傳輸閾值。這樣，在所述當前的信號強度分佈資料中的信號強度平均值大於或等於所述目標傳輸閾值的情況下，用戶端可以與所述支付終端再次進行支付資料傳輸。 在一個具體應用場景中，所述用戶端為智慧手機，所述支付終端為公車上的收銀機具，該收銀機具與該智慧手機透過藍牙進行連接和支付資料傳輸，其中，該收銀機具處於從模式，廣播不同頻段的信號，該智慧手機掃描所述信號，並獲取所述信號對應的信號強度分佈資料。在上次乘坐公車時，用戶透過該智慧手機與該收銀機具進行支付資料傳輸，並完成支付，同時該智慧手機記錄與該收銀機具進行支付資料傳輸時對應的初始傳輸閾值和初始信號強度分佈資料，並根據初始傳輸閾值和初始信號強度閾值，計算下次與該收銀機具進行支付資料傳輸時對應的目標傳輸閾值。用戶再次乘坐公車，上車前準備透過該智慧手機進行支付公共運輸費用，在用戶手持該智慧手機靠近該收銀機具的過程中，可以透過該智慧手機獲取當前的信號強度資料，並判斷當前的信號強度資料中的信號強度平均值大於或等於目標傳輸閾值，當該智慧手機與該收銀機具之間的距離達到指定距離時，判定當前的信號強度資料中的信號強度平均值大於目標傳輸閾值，這時，該智慧手機便可以與該收銀機具再次進行支付資料傳輸。如此，可以自動更新與該智慧手機相適應的傳輸閾值，以使得在通常的支付距離處，用戶使用不同的智慧手機都可以進行正常支付，從而提高用戶的支付體驗。 不僅如此，針對不同的收銀機具，該智慧手機也可以自動更新分別與不同收銀機具進行支付資料傳輸時對應的傳輸閾值，這樣，便可以避免因不同的收銀機具發出的信號強度不同而導致的相容性問題。 在本申請一個實施方式中，由於用戶端與所述支付終端在進行支付資料傳輸之前，需要先建立連接，而通常建立連接需要0.2秒~0.3秒，因此，為了進一步提高用戶的支付體驗，用戶端還可以在與所述支付終端進行支付資料傳輸之前，先與所述支付終端進行預連接。具體地，在判斷所述當前的信號強度分佈資料是否滿足所述目標傳輸閾值關聯的條件之前，所述方法還可以包括以下步驟。 S21：根據所述目標傳輸閾值，確定目標預連接閾值；其中，所述目標預連接閾值小於所述目標傳輸閾值。 在本實施方式中，根據所述目標傳輸閾值，確定目標預連接閾值，具體可以包括，將第一指定係數乘以與所述目標傳輸閾值相關聯的參數，並將所述目標傳輸閾值減去乘積結果，得到所述目標預連接閾值。其中，所述目標預連接閾值小於所述目標傳輸閾值；與所述目標傳輸閾值相關聯的參數可以是與所述目標傳輸閾值相關聯的對數函數。例如，可以採用下述公式表徵所述目標預連接閾值

和
Figure 02_image041
可以分別為100和10。 S23：判斷所述當前的信號強度分佈資料是否滿足所述目標預連接閾值關聯的條件；若滿足，與所述支付終端建立連接。 在本實施方式中，在確定目標預連接閾值之後，用戶端可以獲取當前的信號強度分佈資料，並判斷所述當前的信號強度分佈資料是否滿足所述目標預連接閾值關聯的條件，若滿足，與所述支付終端建立連接。其中，所述目標預連接閾值關聯的條件，具體可以包括：所述當前的信號強度分佈資料中的信號強度平均值大於或等於所述目標預連接閾值。由於所述目標預連接閾值小於所述目標傳輸閾值，用戶在使用用戶端進行支付之前，也就是用戶端與所述支付終端之間的距離大於所述指定距離時，用戶端可以先準備與所述支付終端進行預連接，這樣，在用戶端靠近所述支付終端的過程中，用戶端可以有足夠的時間與所述支付終端建立連接，以使得在用戶端與所述支付終端之間的距離達到所述指定距離時，正好與所述支付終端建立連接，同時，正好當前的信號強度分佈資料滿足所述目標傳輸閾值關聯的條件，用戶端可以直接與所述支付終端進行支付資料傳輸，無需再等待連接，從而可以縮短支付時間。例如，所述指定距離為10厘米，在用戶端與所述支付終端之間的距離為10厘米時，可以與所述支付終端進行支付資料傳輸；用戶手持用戶端，不斷靠近所述支付終端，準備進行支付，當用戶端與所述支付終端之間的距離為30厘米時，獲取的信號強度分佈資料滿足所述目標預連接閾值關聯的條件，可以準備開始與所述支付終端進行預連接，繼續靠近，待用戶端與所述支付終端之間的距離為10厘米時，正好與所述支付終端建立連接，同時，正好當前的信號強度分佈資料滿足所述目標傳輸閾值關聯的條件，便可以直接與所述支付終端進行支付資料傳輸。 在本申請一個實施方式中，在用戶端與所述支付終端建立連接且未與所述支付終端進行資料傳輸的情況下，為了防止因用戶突然離開而導致的該用戶端佔用與所述支付終端的連接資源的現象。所述方法還可以包括以下步驟。 S31：根據所述目標傳輸閾值，確定目標斷開連接閾值；其中，所述目標斷開連接閾值小於所述目標預連接閾值。 在本實施方式中，根據所述目標傳輸閾值，確定目標斷開連接閾值，具體可以包括，將第二指定係數乘以與所述目標傳輸閾值相關聯的參數，並將所述目標傳輸閾值減去乘積結果，得到所述目標預連接閾值。其中，所述目標斷開連接閾值小於所述目標預連接閾值；所述第二指定係數大於所述第一指定係數。與所述目標傳輸閾值相關聯的參數可以是與所述目標傳輸閾值相關聯的對數函數。例如，可以採用下述公式表徵所述目標斷開連接閾值

可以分別為100和10。 S33：在與所述支付終端建立連接且未與所述支付終端進行資料傳輸的情況下，判斷所述當前的信號強度分佈資料是否滿足所述目標斷開連接閾值關聯的條件；若滿足，與所述支付終端斷開連接。 在本實施方式中，在確定所述斷開連接閾值之後，用戶端可以獲取當前的信號強度分佈資料。在與所述支付終端建立連接且未與所述支付終端進行資料傳輸的情況下，用戶端可以判斷所述當前的信號強度分佈資料是否滿足所述目標斷開連接閾值關聯的條件；若滿足，與所述支付終端斷開連接。其中，所述目標斷開連接閾值關聯的條件，具體可以包括：所述當前的信號強度分佈資料中的信號強度平均值小於或等於所述目標預連接閾值。如此，在與所述支付終端建立連接且未與所述支付終端進行資料傳輸的情況下，當用戶突然離開時，用戶端也遠離所述支付終端，導致所獲取的當前的信號強度分佈資料中的信號強度平均值小於所述目標預連接閾值，這時，用戶端便可以與所述支付終端斷開連接，從而可以防止佔用與所述支付終端的連接資源的現象。 在本申請一個實施方式中，在用戶端與所述支付終端建立連接且未與所述支付終端進行支付資料傳輸的情況下，由於用戶被其他事情耽擱而停滯不前，導致用戶端與所述支付終端長時間建立連接，卻不能與所述支付終端進行支付資料傳輸，這樣會浪費所述支付終端的連接資源。為了避免這種情況發生，所述方法還可以包括：在與所述支付終端建立連接且未與所述支付終端進行資料傳輸的情況下，判斷與所述支付終端持續連接的時長是否大於或等於指定連接時長；若與所述支付終端持續連接的時長大於或等於指定連接時長，與所述支付終端斷開連接。其中，所述指定連接時長可以根據實際應用情況來設定，此處不作限定。 在本申請一個實施方式中，在實際應用中，由於所述支付終端廣播的信號受到現實場景影響，其傳播路徑存在多徑折射，這樣會導致用戶端所獲取的信號強度分佈資料中的RSSI值與距離不完全對應，甚至出現較大誤差，即出現跳變的現象，從而導致近場支付的觸發距離並不穩定。例如，如圖4所示，某智慧手機在與某支付終端相距指定距離時獲取的信號強度分佈資料中，RSSI值分別為-62 dbm和-53 dbm的附近出現了跳變現象。其中，圖4中的橫坐標和縱坐標分別為RSSI值和占比，單位分別為毫瓦分貝（dbm）和千分比。為了減少RSSI值跳變現象所帶來的距離誤差，獲取當前的信號強度分佈資料，具體可以包括以下步驟。 S41：獲取當前的信號強度採樣點序列；其中，所述信號強度採樣點序列中包括多個信號強度採樣點。

在本實施方式中，用戶端可以儲存指定時長內的信號強度採樣點序列，在該序列中的信號強度採樣點對應的採樣時間距離當前時間超過所述指定時長，用戶端可以將該序列刪除，並再次獲取當前的所述指定時長內的信號強度採樣點序列。 S43：將所述信號強度採樣點序列劃分為至少一個子序列，並確定所述子序列的信號強度中值。 在本實施方式中，在獲取所述當前的信號強度採樣點序列後，可以按照指定時窗窗長將所述信號強度採樣點序列劃分為至少一個子序列，還可以按照指定採樣點數量，將所述信號強度採樣點序列劃分為至少一個子序列。其中，相鄰兩個子序列有重疊的信號強度採樣點。例如，如圖5所示，相鄰兩個子序列A1和A2，除了子序列A1的第一個信號強度採樣點和子序列A2的最後一個信號強度採樣點以外，其他的信號強度採樣點都是子序列A1和A2中重疊的信號強度採樣點，子序列A2相當於子序列A1移動了一個信號強度採樣點。 在本實施方式中，在將所述信號強度採樣點序列劃分為至少一個子序列之後，可以分別確定每個子序列的信號強度中值，即每個子序列中多個信號強度採樣點的信號強度的中值。 S45：根據所述子序列的信號強度中值，確定所述當前的信號強度分佈資料。 在本實施方式中，根據所述子序列的信號強度中值，確定所述當前的信號強度分佈資料，具體可以包括，可以將所述子序列的信號強度中值作為所述子序列中的中間位置處的信號強度採樣點的信號強度值，或者作為所述子序列中的其他指定位置處的信號強度採樣點的信號強度值。對每個子序列的信號強度中值，均按照上述方式進行處理，從而可以得到處理後的信號強度採樣點，並將這些處理後的信號強度採樣的信號強度值構成的信號強度分佈資料作為所述當前的信號強度分佈資料。例如，如圖6所示，某智慧手機與某支付終端相距指定距離時，在所述指定時長內按照上述方式獲取的信號強度分佈資料中，RSSI值的跳變現象明顯減少很多。 在本申請一個實施方式中，在將所述信號強度採樣點序列劃分為至少一個子序列之後，還可以確定所述子序列的信號強度平均值，並根據所述子序列的信號強度平均值，確定所述當前的信號強度分佈資料。或者，還可以確定所述子序列中部分信號強度採樣點的信號強度平均值，並根據所述子序列中部分信號強度採樣點的信號強度平均值，確定所述當前的信號強度分佈資料。其中，所述部分信號強度採樣點可以是所述子序列的中間部分的信號強度採樣點，所述部分信號強度採樣點的採樣點數量可以是所述子序列的採樣點數量的百分之五十。 在本申請一個實施方式中，在實際應用中，用戶端本身可能會出現故障，導致所獲取的信號強度值始終為較小的值，即使用戶端與所述支付終端之間的距離很近，也可能無法與所述支付終端進行支付資料傳輸，但在這種情況下，用戶端仍會不斷更新傳輸閾值、預連接閾值和斷開連接閾值，所更新的傳輸閾值、預連接閾值和斷開連接閾值為較小的值，不斷嘗試與所述支付終端進行支付資料傳輸，這樣會浪費時間，不利於用戶發現問題。為了避免這種情況，在所述目標傳輸閾值、所述目標預連接閾值和所述目標斷開連接閾值中至少一個閾值小於指定閾值的情況下，例如，所述指定閾值為-100 dbm，用戶端不進行閾值更新和傳輸條件的判定，並給出用戶端支付故障的提示。 在本申請一個實施方式中，在實際應用中，用戶使用的用戶端在與所述支付終端前幾次進行正常支付資料傳輸後，給用戶端套上金屬材質的保護套，而且用戶端的大部分區域都被該保護套包裹，在這種情況下，由於受到保護套的信號遮罩的影響，該用戶端再次獲取的信號強度可能較小，根據上次更新的傳輸閾值，可能很難與所述支付終端再次進行支付資料傳輸。為了避免這種情況發生，用戶端可以將傳輸閾值恢復到首次使用時對應的初始傳輸閾值，以重新更新傳輸閾值。

在20世紀90年代，對於一個技術的改進可以很明顯地區分是硬體上的改進（例如，對二極體、電晶體、開關等電路結構的改進）還是軟體上的改進（對於方法流程的改進）。然而，隨著技術的發展，當今的很多方法流程的改進已經可以視為硬體電路結構的直接改進。設計人員幾乎都透過將改進的方法流程程式設計到硬體電路中來得到相應的硬體電路結構。因此，不能說一個方法流程的改進就不能用硬體實體模組來實現。例如，可程式設計邏輯元件（Programmable Logic Device, PLD）（例如現場可程式設計閘陣列（Field Programmable Gate Array，FPGA））就是這樣一種積體電路，其邏輯功能由用戶對元件程式設計來確定。由設計人員自行程式設計來把一個數位系統“集成”在一片PLD 上，而不需要請晶片製造廠商來設計和製作專用的積體電路晶片。而且，如今，取代手工地製作積體電路晶片，這種程式設計也多半改用 “邏輯編譯器（logic compiler）”軟體來實現，它與程式開發撰寫時所用的軟體編譯器相類似，而要編譯之前的原始代碼也得用特定的程式設計語言來撰寫，此稱之為硬體描述語言（Hardware Description Language，HDL），而HDL 也並非僅有一種，而是有許多種，如ABEL（Advanced Boolean Expression Language）、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 Language）等，目前最普遍使用的是VHDL（Very-High-Speed Integrated Circuit Hardware Description Language ） 與Verilog2。本領域技術人員也應該清楚，只需要將方法流程用上述幾種硬體描述語言稍作邏輯程式設計並程式設計到積體電路中，就可以很容易得到實現該邏輯方法流程的硬體電路。 本領域技術人員也知道，除了以純電腦可讀程式碼方式實現用戶端、伺服器以外，完全可以透過將方法步驟進行邏輯程式設計來使得用戶端、伺服器以邏輯閘、開關、專用積體電路、可程式設計邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種用戶端、伺服器可以被認為是一種硬體部件，而對其內包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。 In order to enable those skilled in the art to better understand the technical solutions in the application, the following will clearly and completely describe the technical solutions in the embodiments of the application in conjunction with the drawings in the embodiments of the application. Obviously, the described The embodiments are only a part of the embodiments of the present application, rather than 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 work shall fall within the protection scope of this application. The embodiments of the present application provide a payment method, which can be applied to the system architecture of the user terminal and the payment terminal. The payment terminal may be a collection device with Bluetooth communication function. When performing Bluetooth communication with the user terminal, the payment terminal is usually in a slave mode and can send signals in the Bluetooth frequency band. Specifically, the payment terminal may be, for example, a collection device such as a Point of Sale (POS) machine with a Bluetooth communication function, a public transportation toll collection machine, a campus toll collection machine, etc.; it can also be running in the collection device, Software that supports payment collection. In this embodiment, the number of payment terminals is not specifically limited. The payment terminal may be one payment terminal, several payment terminals, or a payment terminal cluster formed by several payment terminals. In this embodiment, the user terminal may be an electronic device that is used for mobile payment and has a Bluetooth communication function. When performing Bluetooth communication with the payment terminal, the user terminal is usually in the main mode and can obtain signal strength distribution data corresponding to the signal. Specifically, the user terminal may be, for example, a tablet computer, a notebook computer, a smart phone, a digital assistant, a smart wearable device, etc. Alternatively, the client can also be software that can be run in the aforementioned electronic device. Specifically, the user terminal may be a mobile application in an electronic device, and the mobile application may be, for example, WeChat, PayPal, etc. The embodiment of the present application provides an information interaction method, which can be applied to the above-mentioned user terminal. The method may be provided with initial transmission threshold and initial signal strength distribution data corresponding to when the payment terminal performs payment data transmission. 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 transmission of payment data between the user terminal and the payment terminal, that is, the initially set transmission threshold. Generally, the initially set transmission threshold may be a small value, such as -100 milliwatt decibels (dbm), to ensure that different user terminals, such as different smart phones, can trigger the connection with the payment terminal. Payment data transmission function between the two. Not only that, the initial transmission threshold may also be a transmission threshold corresponding to the payment data transmission performed by the payment terminal for a certain time after the user terminal and the payment terminal perform payment data transmission for the first time. In this embodiment, the initial signal strength distribution data may be a kind of RSSI distribution data. Wherein, the RSSI distribution data may be the RSSI value corresponding to the Bluetooth signal sent by the payment terminal acquired by the user terminal 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 the signal strength distribution data obtained when the user terminal and the payment terminal perform payment data transmission for the first time, or may be the first payment data between the user terminal and the payment terminal. After the transmission, the signal strength distribution data obtained during a certain transmission of payment data with the payment terminal. In this embodiment, when the initial signal strength distribution data meets the conditions associated with the initial transmission threshold, the user terminal may perform payment data transmission with the payment terminal. Specifically, the condition for the initial transmission threshold association may include that the average 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 user terminal transmits payment data with the payment terminal, it can record the transmission threshold and signal strength distribution data corresponding to the payment data transmission with the payment terminal this time, so as to update the payment data with the payment terminal. The target transmission threshold corresponding to the next time the 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 user terminal may determine the target transmission threshold based on the initial transmission threshold and initial signal strength distribution data corresponding to the last time the payment terminal was transmitting payment data, as a re-transmission with the payment terminal Judgment basis for payment data transmission. Specifically, the user terminal may determine based on the number of times the payment terminal has previously transmitted payment data, the designated parameters associated with the number of payment data transmissions, and the maximum signal strength in the initial signal strength distribution data The weight coefficient, so that the target transmission threshold determined according to the weight coefficient, the maximum signal strength in the signal strength distribution data, and the initial transmission threshold is the signal with the largest proportion in the signal strength distribution data corresponding to the specified distance The absolute value of the difference in intensity value is less than or equal to the specified intensity value. Wherein, the specified distance may be the distance between the user terminal and the payment terminal when payment data is usually transmitted, and the distance may be set according to actual application scenarios. For example, when a user makes a payment through a smartphone on a bus, the distance between the smartphone and the charging device on the bus can usually be 5-10 cm. Or, when the user pays through the smart phone in the school cafeteria, the distance between the smart phone and the charging device in the cafeteria window is usually 10-15 cm. The specified intensity value may be zero, or may be a smaller value approaching zero. In this way, when the distance between the user terminal used by the user and the payment terminal is close to the specified distance, the signal strength in the obtained signal strength distribution data is more likely to be greater than the target transmission threshold. In this way, the user terminal can be more Quickly connect with the payment terminal and perform payment data transmission, so that the payment speed can be improved. Not only that, but on the basis of the foregoing implementation manner for determining the target transmission threshold, the average value of the signal strength in the initial signal strength distribution data may be considered. Specifically, the user terminal may also be based on the number of times the payment terminal has previously performed payment data transmissions, the designated parameters associated with the number of payment data transmissions, and the signal strength average value in the initial signal strength distribution data and The maximum value of the signal strength, and the weighting coefficient is determined so that the target transmission threshold determined according to the weighting coefficient, the signal strength average value and the signal strength maximum value in the signal strength distribution data, and the initial transmission threshold is within a specified distance The absolute value of the difference of the signal intensity value with the largest proportion in the corresponding signal intensity distribution data is less than or equal to the specified intensity value. In this embodiment, when the value obtained by subtracting the initial transmission threshold 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 and the initial signal strength Distribute data and determine the target transmission threshold. For example, when the maximum value of the signal strength in the initial signal strength distribution data minus the initial transmission threshold is greater than the specified difference, that is

These are the parameters associated with the specified difference. For example, when the specified difference is 20 dbm,

Figure 02_image024
Can be 15 and 18 respectively. When the maximum value of the signal strength in the initial signal strength distribution data minus the initial transmission threshold is less than or equal to the specified difference, the initial transmission threshold is used as the target transmission threshold, that is, not Update the transmission threshold. In practical applications, the value range of the specified difference can usually be 15-20 dbm. S13: Obtain current signal strength distribution data, and determine whether the current signal strength distribution data meets the 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 user terminal needs to transmit the payment data with the payment terminal again, it can first obtain the current signal strength distribution data, and determine whether the current signal strength distribution data meets the target transmission threshold association conditions of. If it is satisfied, the payment data can be transmitted again with the payment terminal. The condition associated with the target transmission threshold may specifically include: the average signal strength in the current signal strength distribution data is greater than or equal to the target transmission threshold. In this way, in the case where the average signal strength in the current signal strength distribution data is greater than or equal to the target transmission threshold, the user terminal can perform payment data transmission again with the payment terminal. In a specific application scenario, the user terminal is a smart phone, the payment terminal is a cash register device on a bus, and the cash register device is connected to the smart phone via Bluetooth and transfers payment data. The cash register device is in slave mode. , Broadcasting signals of different frequency bands, the smart phone scans the signals, and obtains the signal strength distribution data corresponding to the signals. During the last bus ride, the user used the smartphone to transfer payment data to the cash register device and complete the payment. At the same time, the smartphone records the initial transmission threshold and initial signal strength distribution data corresponding to the payment data transmission to the cash register device , And according to the initial transmission threshold and the initial signal strength threshold, calculate the target transmission threshold corresponding to the next payment data transmission with the cash register device. The user takes the bus again and prepares to pay for public transportation through the smart phone before getting on the bus. When the user is holding the smart phone close to the cash register device, the user can obtain the current signal strength data through the smart phone and determine the current signal The average signal strength in the strength data is greater than or equal to the target transmission threshold. When the distance between the smartphone and the cash register reaches the specified distance, it is determined that the average signal strength in the current signal strength data is greater than the target transmission threshold. , The smart phone can transfer the payment data with the cash register again. In this way, the transmission threshold corresponding to the smart phone can be automatically updated, so that at a normal payment distance, the user can make normal payments using different smart phones, thereby improving the user's payment experience. Not only that, for different cash registers, the smart phone can also automatically update the corresponding transmission thresholds when transmitting payment data with different cash registers. In this way, it can avoid the difference caused by the different signal strengths of different cash registers. Capacitive issues. In one embodiment of the present application, since the user terminal and the payment terminal need to establish a connection before transmitting the payment data, it usually takes 0.2 seconds to 0.3 seconds to establish a connection. Therefore, in order to further improve the user's payment experience, the user The terminal may also pre-connect with the payment terminal before transmitting the payment data with the payment terminal. Specifically, before judging whether the current signal strength distribution data meets the 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 less 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 specified coefficient by a parameter associated with the target transmission threshold, and subtracting the target transmission threshold Multiply the result to obtain the target pre-connection threshold. Wherein, the target pre-connection threshold is less 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 can be used to characterize the target pre-connection threshold

S23: Determine whether the current signal strength distribution data meets the condition of the target pre-connection threshold association; if so, establish a connection with the payment terminal. In this embodiment, after the target pre-connection threshold is determined, the user terminal can obtain the current signal strength distribution data, and determine whether the current signal strength distribution data meets the target pre-connection threshold association condition, if so, Establish a connection with the payment terminal. Wherein, the condition of the target pre-connection threshold association may specifically include: the average signal strength in the current signal strength distribution data is greater than or equal to the target pre-connection threshold. Since the target pre-connection threshold is less than the target transmission threshold, before the user uses the user terminal to make a payment, that is, when the distance between the user terminal and the payment terminal is greater than the specified distance, the user terminal can first prepare to The payment terminal is pre-connected, so that when the user terminal is approaching the payment terminal, the user terminal can have enough time to establish a connection with the payment terminal, so that the distance between the user terminal and the payment terminal When the specified distance is reached, a connection is established with the payment terminal, and at the same time, when the current signal strength distribution data meets the conditions associated with the target transmission threshold, the user terminal can directly transmit payment data with the payment terminal without Wait for the connection again, which can shorten the payment time. For example, the designated distance is 10 cm, and when the distance between the user terminal and the payment terminal is 10 cm, payment data can be transmitted with the payment terminal; the user holds the user terminal and keeps approaching the payment terminal, Ready to make a payment. When the distance between the user terminal and the payment terminal is 30 cm, the acquired signal strength distribution data satisfies the conditions associated with the target pre-connection threshold, and the pre-connection with the payment terminal can be prepared, Continue to approach, when the distance between the user terminal and the payment terminal is 10 cm, the connection is established with the payment terminal, and at the same time, the current signal strength distribution data meets the condition of the target transmission threshold association. Directly transmit payment data with the payment terminal. In one embodiment of the present application, when the user terminal establishes a connection with the payment terminal and does not perform data transmission with the payment terminal, in order to prevent the user terminal from occupying the payment terminal due to the sudden departure of the user The phenomenon of connecting resources. The method may also 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.

S33: When 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 the condition of the target disconnection threshold association; The payment terminal is disconnected. In this embodiment, after the disconnection threshold is determined, the user terminal 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 user terminal can determine whether the current signal strength distribution data meets the condition of the target disconnection threshold association; if so, Disconnect from the payment terminal. Wherein, the condition associated with the target disconnection threshold may specifically include: the average signal strength in the current signal strength distribution data is less than or equal to the target pre-connection threshold. In this way, when a connection is established with the payment terminal and no data transmission is performed with the payment terminal, when the user suddenly leaves, the user terminal is also far away from the payment terminal, resulting in the current signal strength distribution data obtained The average signal strength of is less than the target pre-connection threshold. At this time, the user terminal can disconnect from the payment terminal, thereby preventing the phenomenon of occupying connection resources with the payment terminal. In one embodiment of the present application, when the user terminal establishes a connection with the payment terminal and does not transmit payment data with the payment terminal, the user is delayed by other things and stagnates, causing the user terminal 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 connection resources of the payment terminal. In order to avoid this situation, the method may further include: in the case of establishing a connection with the payment terminal and no data transmission with the payment terminal, determining whether the duration of the continuous connection with the payment terminal is greater than or Equal to the designated connection duration; if the duration of the continuous connection with the payment terminal is greater than or equal to the designated connection duration, the payment terminal is disconnected. Wherein, the specified connection duration can be set according to actual application conditions, which is not limited here. In one embodiment of the present application, in practical applications, since 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 strength distribution data obtained by the user terminal Incomplete correspondence with the distance, or even a large error, that is, a jump phenomenon, which causes the trigger distance of the near-field payment to be unstable. For example, as shown in Figure 4, in the signal strength distribution data obtained when a smart phone is at a specified distance from a payment terminal, the RSSI values of -62 dbm and -53 dbm have jumped around. Among them, the abscissa and ordinate in Figure 4 are the RSSI value and the proportion, respectively, and the units are decibels (dbm) and per thousand respectively. In order to reduce the distance error caused by the jump phenomenon of the RSSI value, obtaining the current signal strength distribution data may specifically include the following steps. S41: Obtain a current signal strength sampling point sequence; wherein the signal strength sampling point sequence includes multiple signal strength sampling points. In this embodiment, the user terminal can obtain a signal strength sampling point corresponding to the signal sent by the payment terminal at a specified time interval. In this way, the user terminal can obtain multiple signal strength samples within the current specified time period. After these signal strength sampling points are arranged in a time sequence, they constitute the current signal strength sampling point sequence. Wherein, 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 seconds 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 user terminal can store a sequence of signal strength sampling points within a specified time period. The sampling time corresponding to the signal strength sampling point in the sequence exceeds the specified time period from the current time. Delete, and obtain the current signal strength sampling point sequence within the specified time period again. S43: Divide the signal strength sampling point sequence into at least one sub-sequence, and determine a median signal strength of the sub-sequence. In this embodiment, after acquiring the current sequence of signal strength sampling points, the sequence of signal strength sampling points may be divided into at least one sub-sequence according to a specified time window length, and the sequence of sampling points may also be divided according to the number of specified sampling points. The signal strength sampling point sequence is divided into at least one sub-sequence. Among them, two adjacent subsequences have overlapping signal strength sampling points. For example, as shown in Figure 5, for 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, the other signal strength sampling points are The overlapping signal strength sampling points in the subsequence A1 and A2, and the subsequence A2 is equivalent to the subsequence A1 moving one signal strength sampling point. In this embodiment, after dividing the sequence of signal strength sampling points into at least one sub-sequence, the median signal strength of each sub-sequence can be determined separately, that is, the signal strength of multiple signal strength sampling points in each sub-sequence. Median. S45: Determine the current signal strength distribution data according to the median signal strength of the subsequence. In this embodiment, determining the current signal intensity distribution data according to the median signal intensity of the subsequence may specifically include: the median signal intensity of the subsequence can be used as the middle value of the subsequence. The signal strength value of the signal strength sampling point at the position, or as the signal strength value of the signal strength sampling point at other designated positions in the subsequence. The median signal strength of each sub-sequence is processed in the above manner, so that the processed signal strength sampling points can be obtained, and the signal strength distribution data composed of the signal strength values of these processed signal strength samples is used as the Current signal strength distribution data. For example, as shown in Fig. 6, when a certain smart phone and a certain payment terminal are separated by a specified distance, the RSSI value jump phenomenon is significantly reduced in the signal strength distribution data obtained in the above-mentioned manner within the specified time period. In an embodiment of the present application, after the sequence of signal strength sampling points is divided into at least one subsequence, the average signal strength of the subsequence can also be determined, and according to the average signal strength of the subsequence, Determine the current signal intensity distribution data. Alternatively, it is also possible to determine the average signal strength of some signal strength sampling points in the sub-sequence, and determine the current signal strength distribution data based on the average signal strength of some signal strength sampling points in the sub-sequence. Wherein, the partial signal strength sampling points may be the signal strength sampling points of the middle part 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 practical applications, the user terminal itself may malfunction, resulting in the signal strength value obtained is always a small value, even if the distance between the user terminal 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 user terminal 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 relatively small value, and continuous attempts to transmit payment data with the payment terminal will waste time and make it difficult for users to discover problems. In order 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 user The terminal does not perform threshold update and determination of transmission conditions, and gives a reminder of the user terminal payment failure. In one embodiment of the present application, in practical applications, after the user terminal used by the user performs normal payment data transmission with the payment terminal several times before, the user terminal is covered with a metal protective cover, and most of the user terminal The area is covered by the protective cover. In this case, due to the influence of the signal mask of the protective cover, the signal strength obtained again by the user terminal may be small. According to the last updated transmission threshold, it may be difficult to The payment terminal transmits the payment data again. In order to avoid this situation from happening, the user terminal can restore the transmission threshold to the corresponding initial transmission threshold at the first use to update the transmission threshold again.

Of course, there are other types of memory, such as quantum memory, graphene memory and so on. In this embodiment, the processor can be implemented in any suitable manner. For example, the processor may take the form of a microprocessor or a processor and a computer-readable medium, logic gates, switches, dedicated products that store computer-readable program codes (such as software or firmware) executable by the (micro) processor Body circuit (Application Specific Integrated Circuit, ASIC), programmable logic controller and embedded microcontroller form, etc. In one embodiment, when the computer program is executed by the processor, the following steps are further implemented: based on the number of transmissions of the payment data, designated parameters associated with the number of transmissions of the payment data, and the initial The maximum value of the signal strength in the signal strength distribution data, and the weight coefficient is determined so that the target transmission threshold determined according to the weight coefficient, the maximum value of the signal strength in the signal strength distribution data and the initial transmission threshold is at a specified distance The absolute value of the difference between the signal strength values with the highest probability in the corresponding signal strength distribution data is less than or equal to the specified strength value.

In the 1990s, the improvement of a technology can be clearly distinguished from the improvement of the hardware (for example, the improvement of the circuit structure of diodes, transistors, switches, etc.) or the improvement of the software (for the method flow Improve). However, with the development of technology, the improvement of many methods and processes of today 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 the hardware entity module. For example, Programmable Logic Device (PLD) (such as Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the component. It is designed by the designer to "integrate" a digital system on a PLD without having to ask the chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized by using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation must also be written in a specific programming language, which is called the Hardware Description Language (HDL), and there is not only one HDL, but many, such as ABEL (Advanced Boolean Expression Language), 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 Language), etc., The most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog2. It should also be clear to those skilled in the art that only a little logic programming of the method flow using the above hardware description languages and programming into an integrated circuit can easily obtain a hardware circuit that implements the logic method flow. Those skilled in the art also know that, in addition to realizing the client and server in a purely computer-readable code, it is entirely possible to design the method steps in logic to make the client and server use logic gates, switches, and dedicated integrated circuits. , Programmable logic controller and embedded microcontroller to achieve the same function. Therefore, the client and server can be regarded as a kind of hardware component, and the devices included in it for realizing various functions can also be regarded as the structure within the hardware component. Or even, the device for realizing various functions can be regarded as both a software module for realizing the method and a structure in a hardware component.
