It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0052] The verification code receiving and sending method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0053] The verification code receiving and sending method, apparatus and device provided in the embodiments of this application can be applied to scenarios where terminals receive verification codes, especially scenarios where terminals including at least two SIM cards receive verification codes.

[0054] In a specific application scenario, the verification code receiving and sending method provided in this application embodiment can be applied to a scenario in which a terminal with two SIM cards receives a verification code, such as scenario 1.

[0055] In Scenario 1, taking SIM1 as the primary SIM card and SIM2 as the secondary SIM card in the terminal, the first application as a video playback application, the user setting the phone number corresponding to the secondary SIM card as the primary phone number, and the first network device as a base station as an example: When the user logs into the video playback application through their video playback account, the terminal can send a verification code request to the application server of the video playback application. This verification code request may include the phone number corresponding to the secondary SIM card. After receiving the verification code request from the terminal, the application server can send the verification code and the phone number corresponding to the secondary SIM card to the base station, enabling the base station to send the verification code to the phone number corresponding to the secondary SIM card. If the base station fails to send the verification code to the phone number corresponding to the secondary SIM card, it can send the verification code, the phone number corresponding to the secondary SIM card, and the user's manufacturer account to the manufacturer's server. The manufacturer's server can then find the phone number corresponding to the primary SIM card associated with the manufacturer account and different from the phone number corresponding to the secondary SIM card, and send the phone number corresponding to the primary SIM card and the verification code to the base station. Finally, the base station can send the verification code to the terminal based on the phone number corresponding to the primary SIM card sent by the manufacturer's server.

[0056] Another specific application scenario is that the verification code receiving and sending method provided in this application embodiment can be applied to a scenario in which a terminal with three SIM cards receives a verification code, such as scenario 2.

[0057] In Scenario 2, taking SIM1 as the primary SIM card and SIM2 and SIM3 as secondary SIM cards, the first application as a financial management application, and the first network device as a base station, the following scenario applies: When a user logs into the financial management application through their financial management account, the terminal can recommend the user's preferred SIM3 to receive verification codes. The terminal can send a verification code request, including the phone number corresponding to SIM3, to the application server of the financial management application. After receiving the verification code request from the terminal, the application server can send the verification code and the phone number corresponding to SIM3 to the base station, enabling the base station to send the verification code to the phone number corresponding to SIM3. If the base station fails to send the verification code to the phone number corresponding to SIM3, it can send the verification code, the phone number corresponding to SIM3, and the user's manufacturer account to the terminal's manufacturer server. This allows the manufacturer server to send the terminal's identifier and verification code to the base station even if no phone number associated with the manufacturer account and different from the phone number corresponding to SIM3 is found. Finally, the base station can send the verification code to the terminal based on the terminal identifier sent by the manufacturer server.

[0058] The verification code receiving and sending method provided in this application embodiment allows the terminal to flexibly select the phone number to receive the verification code through pre-setting or intelligent recommendation when the terminal needs to receive the verification code, thereby eliminating the need for the user to manually enter the phone number to receive the verification code and improving the flexibility of the terminal in receiving verification codes.

[0059] Figure 2 shows a flowchart of a verification code receiving method provided in an embodiment of this application, which can be applied to a terminal including at least two SIM cards. As shown in Figure 2, the verification code receiving method may include the following steps 201 and 202.

[0060] Step 201: The terminal sends a verification code request to the application server of the first application.

[0061] The verification code request may include a first phone number, which may be a pre-set phone number or a phone number recommended by the terminal.

[0062] In this embodiment of the application, the SIM card corresponding to the first phone number can be one of the SIM cards in the terminal's at least two SIM cards.

[0063] In some embodiments of this application, the terminal described above is a terminal that includes at least two SIM cards. It is understood that the terminal including at least two SIM cards refers to a device capable of inserting and using at least two SIM cards.

[0064] In some embodiments of this application, the first application described above can be any application in the terminal.

[0065] It is understandable that the application server of the first application can be a network device that supports the development, operation and deployment of the first application, and can provide a stable, reliable and secure operating environment for the first application, so that the first application can run in the operating environment.

[0066] In some embodiments of this application, if the first application requires verification code verification during the process of running the first application on the terminal, the terminal can send a verification code request to the application server of the first application.

[0067] For example, taking a communication application as the first application. When a user chooses to use a verification code to log in to their communication account in this application, the terminal can send a verification code request to the application server of the communication application to obtain a verification code that can be used to log in to the communication account.

[0068] In some embodiments of this application, the phone number can be the phone number corresponding to the SIM card in the terminal.

[0069] In some embodiments of this application, the aforementioned telephone number may also be referred to as a mobile subscriber number, specifically a Mobile Station International Subscriber Directory Number (MSISDN), which is a publicly disclosed telephone number for a mobile user. Typically, when a calling terminal wants to call another terminal in a Global System for Mobile Communications (GSM) network, the user of the calling terminal can dial the telephone number of that other terminal.

[0070] In some embodiments of this application, the terminal can read the International Mobile Subscriber Identity (IMSI) and Integrated Circuit Card Identity (CCID) from the SIM card and use the IMSI to initiate a registration request to the mobile network. After receiving the registration request from the terminal, the mobile network can verify the legitimacy of the IMSI and assign a Temporary Mobile Subscriber Identity (TMSI) to the terminal, associating the phone number with the IMSI. The phone number can then be pushed to the terminal via Over-the-Air Technology (OTA), or the terminal can request the phone number from the mobile network through a network query interface. In this way, the terminal can store the obtained phone number corresponding to the SIM card and display it in the corresponding user interface.

[0071] In some embodiments of this application, the aforementioned pre-set phone number can be the default phone number set by the user to receive verification codes. It is understood that users can set a default phone number to receive verification codes based on their usage habits and commonly used phone numbers, thereby ensuring the accuracy of the phone number used to receive verification codes.

[0072] In some embodiments of this application, users can manually set the default phone number for receiving verification codes in the terminal's verification code settings interface.

[0073] For example, the terminal's verification code settings interface may include a selection control for the default phone number to receive verification codes, so that users can select the default phone number to receive verification codes by inputting into the selection control.

[0074] In some embodiments of this application, the telephone number recommended by the terminal may include at least one of the following:

[0075] The phone number associated with the first application;

[0076] The phone number that last received the verification code;

[0077] Phone numbers that receive verification codes more frequently than or equal to a first threshold within the first time period.

[0078] In some embodiments of this application, the phone number associated with the first application may be the phone number associated with the application account corresponding to the first application.

[0079] For example, the phone number associated with the first application may be the phone number associated with the application account used to log in to the first application.

[0080] In some embodiments of this application, the phone number that most recently received the verification code may be the phone number that most recently received the verification code in the first application.

[0081] In some embodiments of this application, the phone number that receives verification codes more frequently than or equal to a first threshold during the first time period can indicate that the phone number is a commonly used phone number for receiving verification codes. Therefore, the terminal can recommend the commonly used phone number for receiving verification codes.

[0082] In some embodiments of this application, the first time period and the first threshold mentioned above can be set by the user, can be the terminal default, or can be determined by the terminal based on big data. This application does not impose specific limitations on these embodiments.

[0083] In some embodiments of this application, when the terminal recommends at least two phone numbers, the user can select the phone number to receive the verification code from the at least two phone numbers recommended by the terminal.

[0084] In some embodiments of this application, after the user selects a phone number to receive the verification code, the terminal may also display a prompt asking the user whether to select that phone number as the default for receiving verification codes in the future. If the user selects "yes," the terminal can set that phone number as the default phone number for receiving verification codes; if the user selects "no," the terminal can display recommended phone numbers for the user to choose from the next time a verification code needs to be received.

[0085] In some embodiments of this application, when the terminal recommends at least two phone numbers, the terminal can display the at least two recommended phone numbers in descending order of their usage frequency. In actual implementation, the terminal can also display the at least two recommended phone numbers in any other possible arrangement. This application does not impose specific limitations on these embodiments.

[0086] Step 202: The terminal receives the verification code corresponding to the verification code request from the application server.

[0087] In some embodiments of this application, after receiving a verification code request sent by the terminal, the application server of the first application can return a verification code corresponding to the verification code request to the terminal, so that the terminal can complete the verification of the first application based on the verification code.

[0088] In some embodiments of this application, after receiving a verification code request from a terminal, the application server can generate a random verification code and send the verification code to the terminal.

[0089] For example, the terminal can randomly generate a 4- to 6-digit number sequence as a verification code and send it to the terminal.

[0090] Understandably, if the verification code is correct, the terminal can pass the verification of the first application; if the verification code is incorrect, the terminal can prompt the user to re-enter the correct verification code.

[0091] The verification code receiving method provided in this application allows the terminal to flexibly select the phone number to receive the verification code through pre-setting or intelligent recommendation when the terminal needs to receive the verification code, thereby eliminating the need for the user to manually enter the phone number to receive the verification code and improving the flexibility of the terminal in receiving verification codes.

[0092] In some embodiments of this application, the terminal can receive a verification code by receiving a message from the application server; that is, the message includes a verification code. This message can be any of the following: a short message, a web message, a notification message, or a voice message.

[0093] In some embodiments of this application, after receiving a verification code request from a terminal, the application server may send a short message containing a verification code to the terminal.

[0094] In some embodiments of this application, the aforementioned short message may refer to Short Message Service (SMS), which is a service that transmits short text messages in a mobile network.

[0095] In some embodiments of this application, the aforementioned short messages can be transmitted via the signaling channel of the mobile network. That is, even when the data network of the SIM card in the terminal is unavailable, short messages can still be sent and received.

[0096] It should be noted that the aforementioned mobile network can also be referred to as a mobile communication network. The two terms have the same meaning and can be used interchangeably in this text. For a detailed description of this mobile network, please refer to the detailed description in step 202a below; to avoid repetition, it will not be repeated here.

[0097] In some embodiments of this application, after receiving a verification code request from a terminal, the application server may send a network SMS containing a verification code to the terminal.

[0098] In some embodiments of this application, the aforementioned online text messaging can refer to a text messaging service sent and received via the Internet, which can utilize the Internet as a transmission medium. That is, online text messaging is transmitted via the Internet, rather than through the signaling channels of a mobile communication network.

[0099] In some embodiments of this application, after receiving a verification code request from a terminal, the application server may send a notification message containing a verification code to the terminal.

[0100] In some embodiments of this application, the notification message may be provided by an application, a terminal operating system, or a service.

[0101] In some embodiments of this application, the notification message can be a notification message sent by the server to the terminal via push notification technology. It is understood that in this case, the user does not need to open the application receiving the notification message to receive it.

[0102] In some embodiments of this application, after receiving a verification code request from a terminal, the application server may send a voice message containing a verification code to the terminal.

[0103] For example, the application server can broadcast the verification code directly to the user via voice call.

[0104] In this way, by using various message formats, it is ensured that the terminal can receive the required verification code.

[0105] In some embodiments of this application, referring to FIG2 and FIG3, the above step 202 can also be implemented by the following step 202a.

[0106] Step 202a: The terminal receives a verification code via a second phone number based on the mobile network.

[0107] The second phone number can be either the first phone number or a third phone number associated with the first phone number. The SIM card corresponding to the third phone number is a different SIM card from the SIM card corresponding to the first phone number among the at least two SIM cards mentioned above.

[0108] In some embodiments of this application, the mobile network described above is a network that uses radio waves to communicate between mobile users or between a mobile user and a fixed user. This mobile network allows users to conduct voice, data, and video communications while on the move.

[0109] It is understood that the mobile network may include multiple devices such as terminals, base stations, and core networks (such as gateways, routers, servers, etc.). These multiple devices can be connected through the transmission network, so that they can transmit and exchange data through the transmission network.

[0110] In some embodiments of this application, the mobile network described above may include, but is not limited to, a 3G network, a 4G network, a 5G network, or a 6G network.

[0111] In some embodiments of this application, the terminal can receive short messages or voice messages from an application server via a mobile network.

[0112] In some embodiments of this application, when the communication service of the SIM card corresponding to the first phone number is normal, the second phone number can be the first phone number. In this case, the terminal can directly receive SMS messages, network SMS messages, or voice messages from the application server through the first phone number.

[0113] In some embodiments of this application, if the communication service of the SIM card corresponding to the first phone number is abnormal, the second phone number can be a third phone number associated with the first phone number. In this case, the terminal can receive a verification code corresponding to the verification code request from the application server through the third phone number associated with the first phone number.

[0114] In some embodiments of this application, when the second phone number is a third phone number associated with the first phone number, the signal quality of the SIM card corresponding to the second phone number is greater than the signal quality of the SIM card corresponding to the first phone number.

[0115] In some embodiments of this application, the third phone number associated with the first phone number can be understood as: the SIM card corresponding to the third phone number and the SIM card corresponding to the first phone number can be located in the same terminal; or, the user to whom the third phone number belongs can be the same as the user to whom the first phone number belongs; or, both the third phone number and the first phone number are associated with the user's vendor account.

[0116] In some embodiments of this application, when the second phone number is a third phone number associated with the first phone number, the terminal can receive the verification code through the second phone number corresponding to one of at least two SIM cards whose signal quality is greater than that of the SIM card corresponding to the first phone number.

[0117] In some embodiments of this application, the aforementioned signal quality may include, but is not limited to, at least one of the following: Received Signal Strength Indicator (RSSI), Bit Error Rate (BER), Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

[0118] It should be noted that a detailed description of how to determine the second phone number corresponding to the SIM card with a signal quality greater than that of the SIM card corresponding to the first phone number from at least two SIM cards can be found in the detailed descriptions below on the first network device side and the manufacturer's server side. To avoid repetition, it will not be repeated here.

[0119] It should be noted that the above-mentioned terminal receiving the verification code corresponding to the verification code request from the application server via the second phone number based on the mobile network can also be understood as: the terminal receiving the verification code corresponding to the verification code request from the application server via the SIM card corresponding to the second phone number based on the mobile network.

[0120] In this way, the terminal can receive a verification code from the application server via a first phone number or a phone number associated with that first phone number, based on the mobile network, thereby ensuring that the terminal can receive the verification code.

[0121] In some embodiments of this application, as shown in FIG3 and FIG4, the above step 202 can also be implemented by the following step 202b.

[0122] Step 202b: If receiving the verification code via the mobile network fails, the terminal receives the verification code via the system application or a second phone number through the wireless network.

[0123] It is understandable that if the terminal fails to receive the verification code via a second phone number based on the mobile network, the terminal can receive the verification code via the system application based on the wireless network, or the terminal can receive the verification code via a second phone number based on the wireless network.

[0124] In some embodiments of this application, a wireless network is a network technology that uses radio waves to transmit data, which allows terminals to communicate and exchange data without a physical connection.

[0125] In some embodiments of this application, the wireless network described above may be a data network or Wireless Fidelity (WiFi).

[0126] In some embodiments of this application, the aforementioned system applications may refer to applications that are tightly integrated with the terminal's operating system and provide basic functions and services. These system applications are typically developed by the terminal manufacturer or operating system developer and pre-installed on the terminal.

[0127] In some embodiments of this application, the step 202b described above, "the terminal receives the verification code via a system application or a second telephone number based on a wireless network," can also be implemented through the following steps 202b1 or 202b2.

[0128] Step 202b1: The terminal receives a notification message via a system application based on the wireless network. The notification message includes a verification code.

[0129] In some embodiments of this application, when the terminal's mobile network is unavailable or malfunctions, i.e., when receiving the verification code via the mobile network fails, the terminal can receive a notification message from the application server via the system application based on the wireless network to achieve the reception of the verification code.

[0130] Step 202b2: The terminal receives a network SMS message via a second phone number based on the wireless network. The network SMS message includes a verification code.

[0131] In some embodiments of this application, when the terminal's mobile network is unavailable or malfunctions, i.e., when receiving the verification code via the mobile network fails, the terminal can receive a network SMS from the application server via a second phone number based on the wireless network to achieve the receiving of the verification code.

[0132] In this way, the terminal can also receive verification codes from the application server via the system application or a second phone number through the wireless network, thereby ensuring that the terminal can receive the verification codes.

[0133] In some embodiments of this application, before step 201 above, the verification code receiving method provided in the embodiments of this application may further include the following step 203.

[0134] Step 203: The terminal sends the first message to the terminal's manufacturer's server.

[0135] The first message can indicate the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0136] In some embodiments of this application, the first message is used by the vendor server to query a third phone number associated with the first phone number.

[0137] In some embodiments of this application, both the third telephone number and the first telephone number are associated with the user's vendor account.

[0138] In some embodiments of this application, the manufacturer server of the aforementioned terminal may refer to a server provided by the terminal manufacturer, which can be used to support and manage the terminals it produces.

[0139] For example, the vendor's server can be used to remotely manage and monitor the status and performance of the terminal, such as firmware updates, configuration management, and fault diagnosis.

[0140] For example, the vendor's server can also be used to collect terminal usage data and feedback information, and to perform data analysis to improve products and services.

[0141] For example, the vendor's server can also be used to provide technical support and assistance to users, and to answer questions that users encounter while using the terminal.

[0142] In some embodiments of this application, during the user's use of the terminal, the user can typically register and log in to the terminal's manufacturer account.

[0143] For example, when a user uses a terminal of brand A, the user can register and log in to the manufacturer account corresponding to brand A on that terminal.

[0144] In some embodiments of this application, the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards can be: a binding relationship or mapping relationship between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0145] In some embodiments of this application, the terminal can bind or map the manufacturer account ID to the phone numbers corresponding to the at least two SIM cards to obtain the association between the manufacturer account and the phone numbers corresponding to the at least two SIM cards.

[0146] For example, assuming the terminal includes SIM card 1 and SIM card 2, the association between the user's manufacturer account 1 and the phone numbers corresponding to at least two SIM cards may include the following two associations: manufacturer account 1 - phone number corresponding to SIM card 1, and manufacturer account 1 - phone number corresponding to SIM card 2.

[0147] In some embodiments of this application, after obtaining the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards, the terminal can store and report the association.

[0148] It should be noted that since the mapping relationship between SIM cards and their corresponding phone numbers is one-to-one, the terminal can also obtain the association relationship between the user's manufacturer account and at least two SIM cards. Thus, the association relationship between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards can be determined through the phone numbers corresponding to the SIM cards.

[0149] In some embodiments of this application, the terminal can bind the user's manufacturer account to the phone numbers corresponding to at least two SIM cards in the terminal, and report the binding relationship to the manufacturer server, so that when the communication of the first phone number included in the verification code request is abnormal, the manufacturer server can find other phone numbers that can transmit data.

[0150] In this way, the terminal can report the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards to the manufacturer's server in advance. Therefore, when receiving the verification code through the first phone number fails, the manufacturer's server can use this association to find other phone numbers that can allow the terminal to receive the verification code.

[0151] In some embodiments of this application, before step 201 above, the verification code receiving method provided in the embodiments of this application may further include the following step 204.

[0152] Step 204: The terminal sends a second message to the first network device.

[0153] The second message indicates the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0154] In some embodiments of this application, the first network device described above may be a network device that provides services to the terminal.

[0155] In some embodiments of this application, the first network device described above may be a message relay network device between a terminal and a server.

[0156] For example, the first network device described above may be a base station.

[0157] In some embodiments of this application, the terminal can bind the user's manufacturer account to the phone numbers corresponding to at least two SIM cards in the terminal, and report the binding relationship to the first network device. In the event of a communication failure of the first phone number included in the verification code request, the terminal can find the corresponding manufacturer server through the first network device, so that the manufacturer server can find other phone numbers that can transmit data.

[0158] In this way, the terminal can report the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards to the first network device in advance. Therefore, when receiving the verification code through the first phone number fails, the first network device can find the corresponding manufacturer server through the association. The manufacturer server can then find other phone numbers that can allow the terminal to receive the verification code through the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0159] In some embodiments of this application, the terminal may report the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards to the first network device and the manufacturer server in advance. Therefore, when receiving a verification code through the first phone number fails, the first network device and the manufacturer server can find other phone numbers that can enable the terminal to receive the verification code through the association.

[0160] Figure 5 shows a flowchart of a verification code sending method provided in an embodiment of this application, which can be applied to a first network device. As shown in Figure 5, the verification code sending method may include the following steps 301 and 302.

[0161] Step 301: The first network device receives the first phone number and verification code from the application server.

[0162] In some embodiments of this application, the first network device described above may be a network device that provides services to the terminal.

[0163] In some embodiments of this application, the first network device described above may be a message relay network device between a terminal and a server.

[0164] For example, the first network device described above may be a base station.

[0165] In some embodiments of this application, after the application server receives a verification code request containing a first phone number sent by the terminal, the application server can generate a random verification code and send the first phone number and the verification code to the first network device so that the verification code can be sent to the terminal through the first network device.

[0166] In some embodiments of this application, after the first network device receives the first phone number and verification code sent by the application server, the first network device may send the verification code to the first phone number.

[0167] It is understandable that when the first network device sends a verification code to the terminal, it can send a short message, network SMS, notification message, or voice message containing the verification code to the terminal.

[0168] Step 302: If sending the verification code to the first phone number fails, the first network device sends the verification code to the system application of the third phone number or terminal.

[0169] The third phone number mentioned above can be a phone number associated with the first phone number.

[0170] In this embodiment of the application, the first network device may be a network device that provides services to the terminal.

[0171] In some embodiments of this application, if the signal quality of the SIM card corresponding to the first phone number is poor or abnormal, the terminal may be unable to receive the verification code through the first phone number, thereby causing the first network device to fail to send the verification code to the first phone number.

[0172] In some embodiments of this application, if sending a verification code to a first phone number fails, the first network device may send a verification code to a system application of a phone number or terminal associated with the first phone number to ensure that the terminal can receive the verification code.

[0173] It should be noted that for a detailed description of steps 301 and 302 above, please refer to the relevant description in the verification code receiving method of the above embodiments. To avoid repetition, it will not be repeated here.

[0174] The verification code sending method provided in this application embodiment allows a first network device to send the verification code to a third phone number or the terminal's system application if sending the verification code to the first phone number fails. Thus, even if the SIM card signal corresponding to the first phone number is weak, the terminal can still receive the verification code through other means, ensuring successful reception of the verification code.

[0175] In some embodiments of this application, as shown in FIG5 and FIG6, the above step 302 can also be implemented by the following step 302a.

[0176] Step 302a: If sending the verification code to the first phone number fails, the first network device sends the verification code to the third phone number based on the mobile network.

[0177] In some embodiments of this application, referring to FIG5 and FIG7, the above step 302 can also be implemented by the following step 302b.

[0178] Step 302b: If sending the verification code to the first phone number fails, the first network device sends the verification code to the terminal's system application via the wireless network.

[0179] It should be noted that the relevant technologies and solutions for mobile networks and wireless networks described here can be found in the description of the verification code receiving method in the above embodiments. To avoid repetition, they will not be repeated here.

[0180] Furthermore, a detailed description of how the first network device determines the third telephone number and terminal system application can be found in the following descriptions of steps 303 and 304. To avoid repetition, these details will not be repeated here.

[0181] In this way, if the first network device fails to send the verification code to the first phone number, it can send the verification code to the third phone number via the mobile network, or send the verification code to the terminal's system application via the wireless network, thereby confirming that the terminal can successfully receive the verification code.

[0182] In some embodiments of this application, referring to FIG5 and FIG8, after step 301 above, the verification code sending method provided in the embodiments of this application may further include the following steps 303 to 305.

[0183] Step 303: The first network device receives a third message from the terminal.

[0184] The third message indicates the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards on the terminal.

[0185] Step 304: The first network device sends the first phone number and the manufacturer account to the terminal's manufacturer server based on the association between the first phone number and the user's manufacturer account.

[0186] In some embodiments of this application, the first network device may store associations between a user's vendor account reported by the terminal and the phone numbers corresponding to at least two SIM cards. In other words, the first network device may store at least two associations, each association indicating the association between a user's vendor account and the phone numbers corresponding to at least two SIM cards.

[0187] In some embodiments of this application, after receiving the first phone number and verification code sent by the application server, if sending the verification code to the first phone number fails, the first network device can search for the user's manufacturer account corresponding to the first phone number from the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards, and thus determine the terminal's manufacturer server based on the user's manufacturer account.

[0188] In some embodiments of this application, when the first network device sends the first phone number and manufacturer account to the manufacturer server of the terminal, it may also send the verification code together with the first phone number and manufacturer account to the manufacturer server of the terminal, that is, the verification code, the first phone number and the manufacturer account are a whole data packet.

[0189] Step 305: The first network device receives the first information from the vendor's server.

[0190] The first information may include the identifier of a third phone number or terminal, wherein the third phone number and the first phone number are phone numbers corresponding to different SIM cards in at least two SIM cards.

[0191] It is understandable that both the third and first phone numbers mentioned above are associated with the aforementioned manufacturer's account.

[0192] In some embodiments of this application, the identifier of the terminal described above can be used to send a verification code to the system application of the terminal.

[0193] In some embodiments of this application, after receiving the first phone number and manufacturer account sent by the first network device, the manufacturer server can search for the identifier of other phone numbers or terminals associated with the manufacturer account based on the association between the user's manufacturer account reported by the terminal and the phone numbers corresponding to at least two SIM cards. This allows the first network device to send a verification code to the system application of the third phone number or terminal.

[0194] In some embodiments of this application, if the signal quality of the SIM card corresponding to the first phone number is poor or abnormal, sending the verification code to the first phone number may fail. Therefore, if the first network device detects that the verification code has failed to be sent, the first network device can forward the verification code to the terminal's manufacturer server based on the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards. The manufacturer server can then use push notification technology to send the verification code to the terminal if the other SIM cards on the terminal have good signals or if the terminal is connected to WiFi.

[0195] In some embodiments of this application, if the vendor server finds other phone numbers associated with the first phone number, the vendor server can send the other phone number to the first network device, so that the first network device can send a verification code to the other phone number.

[0196] In some embodiments of this application, if the vendor server does not find a phone number associated with the first phone number, the vendor server may send the terminal's identifier to the first network device, so that the first network device may send a verification code to the terminal's system application.

[0197] In some embodiments of this application, the identifier of the terminal can be a Mobile Station Equipment Identity (MEI).

[0198] Understandably, by using the terminal's identifier, the first network device can send a system notification containing a verification code to the system application of the terminal specified by that identifier via the wireless network.

[0199] In some embodiments of this application, when the first network device receives the first information from the vendor server, it may also simultaneously receive the verification code from the vendor server.

[0200] This allows the verification code to be successfully received and verified even when the SIM card corresponding to the phone number to which the terminal was originally supposed to receive the verification code has a poor signal, thus improving the success rate of receiving the verification code.

[0201] In some embodiments of this application, after step 301 above, the verification code sending method provided in this application embodiment may further include steps 306 and 307 below, and step 302 above can be specifically implemented by step 302c below.

[0202] Step 306: If sending the verification code to the third phone number fails, the first network device sends the first phone number, the third phone number, and the manufacturer account to the terminal's manufacturer server based on the association between the first phone number and the user's manufacturer account, and the association between the third phone number and the user's manufacturer account.

[0203] In some embodiments of this application, when the vendor server returns a third phone number to the first network device, the first network device may send a verification code to the third phone number.

[0204] In some embodiments of this application, if sending a verification code to a third phone number fails, the first network device may send the first phone number, the third phone number, and the manufacturer account to the terminal's manufacturer server based on the association between the first phone number, the third phone number, and the user's manufacturer account.

[0205] In some embodiments of this application, when the first network device sends the first phone number, the third phone number, and the manufacturer account to the manufacturer server of the terminal, it may also send the verification code together with the first phone number, the third phone number, and the manufacturer account to the manufacturer server of the terminal, that is, the verification code, the first phone number, the third phone number, and the manufacturer account are a whole data packet.

[0206] Step 307: The first network device receives the terminal identifier from the vendor's server.

[0207] In some embodiments of this application, after the vendor server receives the first phone number, the third phone number, and the vendor account sent by the first network device, the vendor server can find the phone number associated with the vendor account that is different from both the first phone number and the third phone number.

[0208] In some embodiments of this application, if no phone number associated with the vendor account and different from both the first and third phone numbers is found, the vendor server may send the terminal's identifier to the first network device.

[0209] Step 302c: If sending the verification code to the first phone number fails, the first network device sends the verification code to the terminal's system application based on the terminal's identifier.

[0210] This allows the verification code to be successfully received and verified even when the SIM card corresponding to the phone number to which the terminal was originally supposed to receive the verification code has a poor signal, thus improving the success rate of receiving the verification code.

[0211] Figure 9 shows a flowchart of a verification code sending method provided in an embodiment of this application, which can be applied to a vendor server. As shown in Figure 9, the verification code sending method may include the following steps 401 to 403.

[0212] Step 401: The vendor server receives the first phone number and the user's vendor account from the first network device.

[0213] Step 402: If a third phone number is found that is associated with the vendor account and is different from the first phone number, the vendor server sends the third phone number to the first network device.

[0214] Step 403: If no phone number associated with the manufacturer account and different from the first phone number is found, the manufacturer server sends the identifier of the terminal corresponding to the manufacturer account to the first network device.

[0215] In some embodiments of this application, the manufacturer's server may store the association relationships between a user's manufacturer account reported by the terminal and the phone numbers corresponding to at least two SIM cards. In other words, the manufacturer's server may store at least two association relationships, each indicating the association relationship between a user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0216] In some embodiments of this application, the vendor server may also store the association between the terminal's identifier and the user's vendor account, so that the vendor server can find the terminal's identifier based on the user's vendor account.

[0217] In some embodiments of this application, the manufacturer server may receive and store the association between the terminal's identifier and the user's manufacturer account reported by the terminal; or, the manufacturer server may directly receive and store the association between the terminal's identifier, the user's manufacturer account, and the phone numbers corresponding to at least two SIM cards reported by the terminal. The embodiments of this application are not specifically limited.

[0218] It can be understood that the execution relationship between steps 402 and 403 above is an "OR" relationship, and one of these two steps will be executed.

[0219] It should be noted that for a detailed description of steps 401 to 403 above, please refer to the descriptions of steps 301 to 305 and their related steps, as well as steps 201 and 202 and their related steps. To avoid repetition, they will not be repeated here.

[0220] This allows the verification code to be successfully received and verified even when the SIM card corresponding to the phone number to which the terminal was originally supposed to receive the verification code has a poor signal, thus improving the success rate of receiving the verification code.

[0221] In some embodiments of this application, referring to FIG9 and FIG10, after step 402 above, the verification code sending method provided in the embodiments of this application may further include the following steps 404 and 405.

[0222] Step 404: The vendor server receives the first phone number, the third phone number, and the vendor account from the first network device.

[0223] Step 405: If no phone number associated with the manufacturer account is found that is different from both the first and third phone numbers, the manufacturer server sends the terminal's identifier to the first network device.

[0224] Understandably, if the terminal fails to receive the verification code via the first and third phone numbers, the first network device sends the first and third phone numbers, along with the vendor account, to the vendor server. The vendor server then searches for a phone number associated with the vendor account that is different from both the first and third phone numbers to send the verification code. If no phone number is found that is associated with the vendor account and is different from both the first and third phone numbers, the vendor server can indicate the terminal's identifier to the first network device. This allows the first network device to send the verification code to the terminal's system application based on the terminal's identifier, enabling the terminal to receive the verification code through the system application.

[0225] It should be noted that for a detailed description of steps 404 and 405 above, please refer to the descriptions of steps 301 to 305 and their related steps, as well as steps 201 and 202 and their related steps. To avoid repetition, they will not be repeated here.

[0226] This allows the verification code to be successfully received and verified even when the SIM card corresponding to the phone number to which the terminal was originally supposed to receive the verification code has a poor signal, thus improving the success rate of receiving the verification code.

[0227] Figure 11 shows a flowchart of a verification code receiving and sending method provided in an embodiment of this application. As shown in Figure 11, the verification code receiving and sending method may include the following steps 501 to 508.

[0228] Step 501: The terminal sends a verification code request to the application server of the first application through the first network device.

[0229] The verification code request may include a first phone number, which may be a pre-set phone number or a phone number recommended by the terminal, and the SIM card corresponding to the first phone number may be one of the terminal's at least two SIM cards.

[0230] Step 502: The application server receives the verification code request sent by the terminal and sends the first phone number and verification code to the first network device.

[0231] Step 503: The first network device receives the first phone number and verification code from the application server.

[0232] Step 504: If sending the verification code to the first phone number fails, the first network device sends the first phone number and the manufacturer account to the terminal's manufacturer server based on the association between the first phone number and the user's manufacturer account.

[0233] Step 505: The vendor server receives the first phone number and the user's vendor account from the first network device.

[0234] Step 506: If a third phone number associated with the manufacturer account and different from the first phone number is found, the manufacturer server sends the third phone number to the first network device; or if no phone number associated with the manufacturer account and different from the first phone number is found, the manufacturer server sends the identifier of the terminal corresponding to the manufacturer account to the first network device.

[0235] Step 507: The first network device sends a verification code to the system application of the third phone number or terminal.

[0236] Step 508: The terminal receives the verification code and performs the verification.

[0237] The verification code receiving and sending method provided in this application allows for flexible selection of the receiving phone number when a terminal needs to receive a verification code. This can be achieved through pre-setting or intelligent recommendation, eliminating the need for the user to manually enter the receiving phone number and improving the flexibility of the terminal in receiving verification codes. Furthermore, if sending the verification code to the first phone number fails, the first network device can send the verification code to a second phone number or the terminal's system application. Thus, even if the SIM card signal corresponding to the first phone number is weak, the terminal can still receive the verification code through other means, ensuring successful reception of the verification code.

[0238] Each of the above-described method embodiments, or various possible implementations of each method embodiment, can be executed individually or in combination of any two or more, depending on actual usage requirements. This application embodiment does not impose any limitations in this regard. The following specific examples illustrate the verification code receiving and sending method provided by this application embodiment.

[0239] Taking a terminal with SIM1 as the primary SIM card, SIM2 as the secondary SIM card, a video playback application as the first application, a user setting the phone number corresponding to the secondary SIM card as the primary phone number, and a base station as the primary network device as an example.

[0240] Example 1: As shown in Figure 12, the verification code receiving and sending method provided in this application embodiment may include the following steps S101 to S105.

[0241] Step S101: The terminal detects the dual-SIM status.

[0242] It's understandable that when the terminal is powered on or a SIM card is inserted, it can detect whether a SIM card is currently inserted and the number of SIM cards inserted. Furthermore, the terminal can determine the primary and secondary SIM cards. Typically, the primary and secondary SIM cards are determined through user settings or default settings. For example, by default, the terminal's SIM1 is set as the primary SIM card, and SIM2 as the secondary SIM card.

[0243] Step S102: The terminal sets the phone number corresponding to the secondary SIM card as the default phone number for receiving verification codes based on the user's input.

[0244] Users can manually set the default phone number for receiving verification codes in the verification code settings interface. This interface can include a "Default Phone Number for Receiving Verification Codes" option, allowing users to select either the phone number associated with their primary SIM card or the phone number associated with their secondary SIM card as the default verification code recipient.

[0245] Step S103: The terminal sends a verification code request to the application server.

[0246] When a user opens an application that requires a verification code to log in or verify their identity (i.e., the first application mentioned above), if the user clicks on a phone number (i.e., the phone number) to log in to their account, the terminal can send a verification code request through the application using the user's preset default phone number for receiving verification codes. This verification code request may include the default phone number selected by the user for receiving verification codes.

[0247] Step S104: The application server receives the verification code request and sends the verification code to the phone number.

[0248] Step S105: The terminal receives the verification code and verifies the login.

[0249] Users can receive a verification code via a selected phone number, which can be sent via SMS or phone call.

[0250] After receiving the verification code, the user can enter it to complete the account login verification. Understandably, if the verification code is correct, the user can successfully log in; if the verification code is incorrect, the terminal can prompt the user to re-enter the verification code.

[0251] In this way, when a terminal needs to receive a verification code, the phone number to receive the verification code can be flexibly selected through pre-setting or intelligent recommendation, thus eliminating the need for the user to manually enter the phone number to receive the verification code and improving the flexibility of the terminal in receiving verification codes.

[0252] Example 2: As shown in Figure 13, the verification code receiving and sending method provided in this application embodiment may include the following steps S201 to S205.

[0253] Step S201: The terminal detects the dual-SIM status.

[0254] Step S202: The terminal displays the recommended phone number and determines the phone number to receive the verification code based on the user's input.

[0255] When a user opens an application that requires verification code login or identity verification, if the user clicks on phone number login, the device can provide a selection interface displaying recommended phone numbers. For example, the device could display two options: the phone number corresponding to the primary SIM card and the phone number corresponding to the secondary SIM card. The user can then choose to use either the primary or secondary SIM card's phone number to receive the verification code.

[0256] Furthermore, after the user selects a phone number, the terminal can pop up a window asking the user whether they want to use the phone number associated with the secondary SIM card to receive verification codes by default. If the user selects "yes," the terminal can automatically save the phone number associated with the secondary SIM card as the default phone number for receiving verification codes in the settings.

[0257] Step S203: The terminal sends a verification code request to the application server.

[0258] Step S204: The application server receives the verification code request and sends the verification code to the phone number.

[0259] Step S205: The terminal receives the verification code and verifies the login.

[0260] In this way, when a terminal needs to receive a verification code, the phone number to receive the verification code can be flexibly selected through pre-setting or intelligent recommendation, thus eliminating the need for the user to manually enter the phone number to receive the verification code and improving the flexibility of the terminal in receiving verification codes.

[0261] Example 3: As shown in Figure 14, the verification code receiving and sending method provided in this application embodiment may include the following steps S301 to S313.

[0262] Step S301: The terminal detects the dual-SIM status.

[0263] Step S302: The terminal obtains the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards.

[0264] After a user logs into the manufacturer's account on the terminal, the terminal can establish and record the binding relationship between that manufacturer's account and the two SIM cards. Specifically, the terminal can record the following mapping relationship: SIM card 1 - Manufacturer account ID, SIM card 2 - Manufacturer account ID, to ensure that a clear one-to-one association is established between each SIM card and its corresponding manufacturer account.

[0265] Step S303: The terminal reports the association between the user's manufacturer account and the phone numbers corresponding to at least two SIM cards to the base station and the manufacturer's server.

[0266] Step S304: The terminal sends a verification code request to the application server through the secondary SIM card.

[0267] Step S305: The application server receives the verification code request sent by the terminal and sends the phone number and verification code corresponding to the secondary SIM card to the base station.

[0268] Step S306: The base station receives the first phone number and verification code from the application server.

[0269] Step S307: If sending the verification code to the phone number corresponding to the secondary SIM card fails, the base station sends the verification code, the phone number corresponding to the secondary SIM card, and the manufacturer account to the terminal's manufacturer server based on the association between the phone number corresponding to the secondary SIM card and the user's manufacturer account.

[0270] It is understandable that if the secondary SIM card cannot receive the verification code normally due to poor network conditions, the base station can forward the verification code to the device manufacturer's server based on the association between the phone number corresponding to the secondary SIM card and the user's manufacturer account when it detects the verification code transmission failure.

[0271] Step S308: The manufacturer's server receives the verification code, the phone number corresponding to the secondary SIM card, and the user's manufacturer account from the base station.

[0272] Step S309: If a phone number corresponding to the primary SIM card that is associated with the manufacturer's account and is different from the phone number corresponding to the secondary SIM card is found, the manufacturer's server sends the phone number and verification code corresponding to the primary SIM card to the base station.

[0273] Step S310: The first network device receives the phone number and verification code corresponding to the primary SIM card. If sending the verification code to the phone number corresponding to the primary SIM card fails, the device sends the verification code, the phone number corresponding to the secondary SIM card, the phone number corresponding to the primary SIM card, and the manufacturer account to the terminal's manufacturer server based on the association between the phone number corresponding to the secondary SIM card, the phone number corresponding to the primary SIM card, and the user's manufacturer account.

[0274] Step S311: If no phone number associated with the manufacturer's account is found, and the phone number corresponding to the secondary SIM card is different from the phone number corresponding to the primary SIM card, the manufacturer's server sends the terminal's identifier and verification code to the base station.

[0275] Step S312: The base station sends a verification code to the terminal's system application based on the terminal's identifier.

[0276] Step S313: The terminal receives the verification code and verifies the login.

[0277] Therefore, when a terminal needs to receive a verification code, the phone number to receive the verification code can be flexibly selected through pre-setting or intelligent recommendation, eliminating the need for the user to manually enter the phone number and improving the flexibility of the terminal in receiving verification codes. Furthermore, if sending the verification code to the first phone number fails, the first network device can send the verification code to a second phone number or the terminal's system application. Thus, even if the SIM card signal corresponding to the first phone number is weak, the terminal can still receive the verification code through other means, ensuring successful reception of the verification code.

[0278] The verification code receiving method provided in this application can be executed by a verification code receiving device; the verification code sending method provided in this application can also be executed by a verification code sending device. This application uses a verification code receiving device executing the verification code receiving method as an example to illustrate the verification code receiving device provided in this application; this application uses a verification code sending device executing the verification code sending method as an example to illustrate the verification code sending device provided in this application.

[0300] The verification code receiving device provided in this application embodiment can flexibly select the phone number to receive the verification code by pre-setting or intelligent recommendation when the verification code receiving device needs to receive the verification code, thereby eliminating the need for the user to manually enter the phone number to receive the verification code and improving the flexibility of the terminal in receiving verification codes.
