[0059] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] The calling method of the virtual number provided in this application can be applied to Figure 1In the application environment shown in FIG.

[0061] Among them, the terminal 102 can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited to these.

[0062] The server 104 may be an independent physical server or a service node in a blockchain system. The service nodes in the blockchain system form a peer-to-peer (P2P) network. The P2P protocol is an application layer protocol running on the Transmission Control Protocol (TCP).

[0063] In addition, server 104 can also be a server cluster composed of multiple physical servers, and can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), as well as big data and artificial intelligence platforms.

[0064] The terminal 102 and the server 104 may be connected via Bluetooth, USB (Universal Serial Bus) or a network or other communication connection methods, which are not limited in this application.

[0065] In one embodiment, Figure 2 As shown, a calling method for a virtual number is provided, which can be applied to a terminal or a server. Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0066] S202, after obtaining the user's authorization authority, obtain the business information and the user's communication account.

[0067] Among them, business information refers to user information, loan information, call result information, etc. User information refers to user name, user level, user communication account and user relationship (self, friend, family, etc.), overdue days, pending stage (M1, M2, M3), user priority and other information related to the user; loan information refers to loan type, loan name, loan amount, loan date, repayment date and other information related to the user's loan; call result information refers to the number of calls made, the number of calls made on the day, the connection status of the last round of calls, whether the user promises to repay, the last round of outbound call numbers and other information related to the calling user. The more overdue days, the higher the pending stage. For example, the user level can be used to determine the line priority. The higher the user level, the higher the line priority. When making an outbound call, a better dialing line can be selected. When the overdue period is 1 to 5 days, the reminder stage is M1, and when the overdue period is 5 to 15 days, the reminder stage is M2; user priorities include: high priority (A01), normal priority (A02), low priority (A03); the number of calls on the day includes: 1 time (B01), 2 times (B02), 3 times (B03).

[0068] The user communication account is the account used by the user for communication, which can refer to a landline number, mobile phone number, etc.

[0069] Specifically, after obtaining user authorization, the terminal can obtain business information and user communication accounts from the business system that stores business information and user communication accounts. The terminal can also receive virtual number call instructions and process the business information and user communication accounts stored in the terminal.

[0070] In one embodiment, after S202, the terminal determines whether the user communication account is a virtual type of number; when the user communication account is a virtual type of number, a calling operation is performed based on the user communication account; when the user communication account is not a virtual type of number, a step of splicing the service information and the user communication account to obtain a spliced ​​string is executed.

[0071] In one embodiment, after S202, the terminal determines whether the user communication account is a virtual type of number; when the user communication account is not a virtual type of number, the user communication account is verified for integrity and correctness; after the user communication account is verified, the step of splicing the service information and the user communication account to obtain a spliced ​​string is executed.

[0072] In one embodiment, after S202, the terminal verifies the integrity and correctness of the user communication account; when the user communication account verification fails, the user communication account is recorded as an abnormal user communication account; an error message is generated based on the abnormal user communication account, and the error message is sent to the server and the call ends.

[0073] S204, concatenate the business information and the user communication account to obtain a concatenated string.

[0074] In one embodiment, before S204, the terminal screens the business information to obtain the business information that is preset and spliced ​​with the user's communication account. For example, the business information includes user information, loan information, and call result information. The business information is screened to obtain the business information that is preset and spliced ​​with the user's communication account: user priority: high priority (A01), call once a day (B01).

[0075] Specifically, the terminal may concatenate the service information and the user communication account in a preset order to obtain a concatenated character string.

[0076] Among them, the preset order can be business information first, user communication account second; business information second, user communication account first, etc.

[0077] For example, the service information is high priority (A01), the call is made once on the same day (B01), the user communication account is 150xxxxxxxx, and the preset order is service information first and user communication account second. "A01", "B01", and "150xxxxxxxx" are concatenated to obtain the concatenated string "A01B01150xxxxxxxx".

[0078] S206, determining whether a hash value matching the concatenated string is stored; if not, performing a hash operation on the concatenated string to obtain a hash value.

[0079] Among them, the hash algorithm can be used for hash operation. The hash algorithm refers to an algorithm that can perform hash operation on an input of any length (user communication account) to obtain an output of a fixed length (hash value). It can be called a hash algorithm. Commonly used hash algorithms include: Message-Digest Algorithm (MD5), Secure Hash Algorithm (SHA) and other algorithms.

[0080] Specifically, the terminal determines whether there is a hash column matching the concatenated string; if not, it determines that no hash value matching the concatenated string is stored; and performs a hash operation on the concatenated string to obtain a hash value. S206 also includes: the terminal initializes the hash column based on the hash value.

[0081] In one embodiment, the terminal determines that there is a hash column that matches the concatenated string, obtains a hash value from the hash column, performs self-increment processing on the hash value, obtains a new hash value, concatenates the new hash value with the encrypted string obtained by encrypting the concatenated string, and uses the concatenated result as a virtual new virtual number to be dialed; in response to the call operation, makes a call based on the new virtual number.

[0082] S208, concatenating the hash value with the encrypted string obtained by encrypting the concatenated string, and using the concatenated result as a virtual number to be dialed.

[0083] Among them, the encryption algorithm used for encrypting the concatenated string can be: RSA algorithm, Data Encryption Standard (DES) algorithm, Triple DES (3DES) algorithm, Advanced Encryption Standard (AES) algorithm, International Data Encryption Algorithm (IDEA), BLOWFISH and other encryption algorithms.

[0084] Specifically, the terminal may use the RSA algorithm to encrypt the concatenated string with a private key to obtain an encrypted string, concatenate the hash value with the encrypted concatenated string in a preset order, and use the concatenated result as the virtual number to be dialed.

[0085] The preset order may be: hash value first, encrypted string second, hash value second, encrypted string first, etc.

[0086] For example, the hash value is "20210906000001", the concatenated string is "A01B01150xxxxxxxx", the concatenated string is encrypted to obtain the encrypted string "AE82df", the preset order is the hash value first and the encrypted string later, the hash value "20210906000001" and the encrypted string "AE82df" are concatenated in the preset order to obtain "20210906000001AE82df" as the virtual number to be dialed.

[0087] S210: In response to the calling operation, making a call based on the virtual number.

[0088] In one embodiment, Figure 3 The algorithm diagram of the calling method of a virtual number in another embodiment may include:

[0089] (1) The terminal obtains service information. When the user communication account is not a virtual number and the user communication account is judged (verified) to be normal, the service information and the user communication account are concatenated to obtain a concatenated string, and the concatenated string is encrypted. If a hash value is stored, the hash value is incremented to obtain a new hash value. After the new hash value is concatenated with the encrypted concatenated string, a virtual number is obtained, a call is made to the virtual number, and a soft phone exchange is performed. The virtual number is decrypted through the line management platform, and finally the network service provider calls the user communication account.

[0090] (2) The terminal obtains service information. When the user communication account is not a virtual number, it is determined (verified) that the user communication account is normal, and the service information and the user communication account are concatenated to obtain a concatenated string. The concatenated string is encrypted. If the hash value is not stored, a hash operation is performed on the concatenated string to obtain a hash value. The hash value is concatenated with the encrypted concatenated string to obtain a virtual number. A call is made to the virtual number, and a soft phone exchange is performed. The virtual number is decrypted through the line management platform, and finally the network service provider calls the user communication account.

[0091] (3) The terminal obtains service information. When the user communication account is not a virtual number and it is determined (verified) that the user communication account is abnormal, an abnormality is recorded.

[0092] (4) The terminal obtains service information. When the user's communication account is a virtual number, a call is made to the virtual number, and a softphone exchange is performed. The virtual number is decrypted by the line management platform, and finally the network service provider calls the user's communication account.

[0093] The calling method of the above virtual number obtains the business information and the user communication account after obtaining the user authorization authority; splices the business information and the user communication account to obtain a spliced ​​string; determines whether a hash value matching the spliced ​​string is stored, and if not, performs a hash operation on the spliced ​​string to obtain a hash value; splices the hash value with the encrypted string obtained by encrypting the spliced ​​string, and uses the spliced ​​result as the virtual number to be dialed; responds to the call operation, and makes a call based on the virtual number. Through the encryption and splicing technology of the user communication account, the encrypted transmission of the user communication account between various systems is realized, and the normal number is restored only when calling, so that the internal circulation is safe and controllable. At the same time, the virtual number is used as the unique serial number of the entire call process, which connects the entire call process in series, which is convenient for problem location. In addition, the business information and the user communication account are spliced, and after being decrypted and read on the line management platform, it is convenient to select the optimal outbound call number and landing gateway and other lines.

[0094] In one embodiment, Figure 4 As shown, the calling steps of the virtual number may include:

[0095] S402, in response to the call operation, decrypt the encrypted string in the virtual number to obtain a concatenated string; extract the service information and the user communication account from the concatenated string.

[0096] In one embodiment, the terminal can respond to a call operation, send the virtual number to a softphone switching platform (e.g., FreeSwitch platform) for softphone switching, transmit the virtual number to a line management platform, and decrypt the encrypted string based on the stored public key and ciphertext to obtain a concatenated string; extract business information and user communication account from the concatenated string.

[0097] For example, the virtual number is "20210906000001AE82df". The terminal can intercept the last six digits of the virtual number to obtain the encrypted string "AE82df", decrypt the encrypted string "AE82df", and obtain the concatenated string "A01B01150xxxxxxxx". Extract the business information and user communication account from the concatenated string "A01B01150xxxxxxxx", and obtain the business information "A01" and "B01", and the user communication account "150xxxxxxxx".

[0098] S404, determining the outbound call number based on the priority in the service information.

[0099] Among them, the priority refers to the customer priority, for example, high priority (A01), normal priority (A02), low priority (A03), and the outbound number is the number used to dial the user's communication account.

[0100] For example, when the customer priority is high priority (A01), you can use numbers with higher fixed-line connection rates as outbound numbers, such as numbers in the 95 and 400 ranges. When the customer priority is normal priority (A02), you can use general numbers as outbound numbers.

[0101] S406: When the number of dialing times in the service information does not reach the preset condition, a call is made to the user's communication account based on the outbound call number.

[0102] The preset condition is a limiting condition on the number of dialing times during the dialing process. For example, the preset condition may refer to the number of successful dialing times being greater than or equal to a preset threshold.

[0103] In one embodiment, when the number of successful dialing in the service information is less than a preset threshold, the terminal calls the user's communication account based on the outbound call number.

[0104] For example, the preset threshold is 1, and when the number of successful dialing is less than 1, the terminal calls the user's communication account based on the outbound call number.

[0105] In one embodiment, when the number of dialing times in the service information reaches a preset condition, calling the user's communication account is stopped.

[0106] In one embodiment, when the number of successful dialing in the service information is greater than or equal to a preset threshold, calling the user's communication account is stopped.

[0107] For example, when the preset threshold is 1, when the number of successful dialing is greater than or equal to 1, calling the user communication account is stopped.

[0108] In one embodiment, after S406, after the terminal call is connected, the service information can be used to

[0109] In one embodiment, before the terminal calls the virtual number, it can also select different outbound numbers, dialing lines, and speech content according to the business information, and determine whether to continue the call next time.

[0110] For example, if the user's waiting stage is M2, you can set more rounds of dialing times and choose an outbound number in the 95 or 400 range with a higher connection rate than ordinary fixed-line numbers to call the user's communication account. At the same time, choose more serious words to talk to the user based on the business information.

[0111] If the user promises to repay the loan according to the call result information in the service information, no call will be made next time. If the user's communication account has been called multiple times with the same outbound call number but has not been connected, a new outbound call number will be used. If the user's communication account has been called with the same line but has been hung up, a new call line will be switched.

[0112] In this embodiment, the encrypted string in the virtual number is decrypted to obtain a concatenated string; the service information and the user communication account are extracted from the concatenated string. The outbound call number is determined based on the priority in the service information. When the number of dials in the service information does not reach the preset condition, the user communication account is called based on the outbound call number, and the encrypted transmission of the user communication account between various systems is realized. The normal number is restored only when a call is made, and the internal circulation is safe and controllable. At the same time, the outbound call number is determined based on the priority in the service information, which improves the connection rate.

[0113] It should be understood that although Figure 2-4 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-4 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
