[0002] Number blocking is an important feature offered by smartphones and telecommunications operators, designed to help users reduce unwanted nuisance and scam calls.
[0003] Current number blocking methods typically involve persistently storing a large number of reference numbers (such as numbers to be blocked) locally, or using a database or FTP (File Transfer Protocol) file server. When a call number is obtained, the system checks the stored reference numbers to see if the number exists, and then blocks the call based on the query result.

[0071] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0072] Reference Figure 1 The diagram illustrates a flowchart of a number blocking method according to an embodiment of this application.
[0073] like Figure 1 As shown, the number blocking method may include the following steps:
[0074] Step 101: Convert the reference number into N reference sub-objects in advance according to the target conversion method, and for each reference sub-object, map and store the reference sub-object into bitmap data.
[0075] In this embodiment of the application, the reference number refers to the number that needs to be saved as the basis for number interception.
[0076] For example, the reference number can be a number that needs to be blocked, or a number that does not need to be blocked. For example, the number that needs to be blocked can be a scam phone number, a telemarketing phone number, a harassing phone number, and so on. For example, the number that does not need to be blocked can be other phone numbers besides the numbers mentioned above that need to be blocked, and so on.
[0077] In this embodiment, the reference sub-object refers to a sub-object obtained by converting a reference number. The reference sub-object can be a value calculated from the reference number, or it can be a portion of the extracted reference number.
[0078] The specific value of N can be set according to actual needs, and this embodiment does not impose any restrictions on it. For example, N can be set to 2, 3, etc.
[0079] In one optional implementation, the process of converting a reference number into N reference sub-objects in advance according to the target conversion method may include: performing a first calculation on the reference number to obtain a first reference sub-object, performing a second calculation on the reference number to obtain a second reference sub-object, and determining the first reference sub-object and the second reference sub-object as the N reference sub-objects.
[0080] For example, the process of performing a first calculation on the reference number to obtain a first reference sub-object may include: dividing the reference number by a preset value to obtain a reference quotient, and using the integer part of the reference quotient as the first reference sub-object. Wherein, the preset value is 10. n n is a positive integer less than the number of digits (total number of digits) of the reference number.
[0081] In this method, the first reference sub-object is specifically the first L digits of the reference number, where L is the difference between the number of digits in the reference number and n.
[0082] For example, for a reference number that is 11 digits long, the value is set to 10. 7 That is, 10000000, then the first reference sub-object obtained after calculation is the first 4 digits of the reference number.
[0083] The specific value of n can be set according to actual needs, and this embodiment does not impose any restrictions on it.
[0084] For example, the process of performing a second calculation on the reference number to obtain a second reference sub-object may include: converting the reference number into a reference binary number of a set number of bits, performing a bitwise AND operation between the reference binary number and the mask binary number of the set number of bits to obtain a first binary number, and using the decimal number corresponding to the first binary number as the second reference sub-object. Wherein, the first m bits of the mask binary number are 0, the last m bits are 1, and m is half of the set number of bits.
[0085] In the process of converting the reference number into a reference binary number with a set number of bits, the reference number can first be converted into a binary number, which is called the initial reference binary number. If the number of bits in the initial reference binary number is less than the set number of bits, zeros are padded in front of the first digit of the initial reference binary number until the sum of the number of zeros padded and the number of bits in the initial reference binary number reaches the set number of bits. The resulting binary number is the reference binary number with the set number of bits.
[0086] The reference number is a decimal number. For the process of converting a decimal number to a binary number, any applicable method can be selected based on practical experience.
[0087] For example, decimal numbers can be converted to binary numbers using methods such as "dividing by 2 and taking the remainder" or "program calculation".
[0088] For example, the process of the "divide by 2 and take the remainder method" is as follows:
[0089] (1) Divide a decimal number by 2: First, divide the decimal number to be converted by 2.
[0090] (2) Record the remainder: After each division operation, record the remainder (0 or 1). This remainder is one bit in the binary number.
[0091] (3) Repeat steps (1) and (2) for the quotient: divide the quotient obtained in the previous step by 2 again and record the remainder. Repeat this process until the quotient is 0.
[0092] (4) Reverse the order of remainders: Arrange all the recorded remainders in reverse order (i.e., place the first remainder in the least significant bit and the last remainder in the most significant bit). The resulting number is the binary representation of the original decimal number.
[0093] In the process of performing a bitwise AND operation between the reference binary number and the mask binary number of a set number of bits, the bitwise AND operation refers to performing a logical AND operation between each bit of the reference binary number and the corresponding bit of the mask binary number. If the value of the bit being ANDed is 1 in both the reference binary number and the mask binary number, the result of the bitwise AND operation is 1; otherwise, the result of the bitwise AND operation is 0. The i-th bit in the reference binary number corresponds to the i-th bit in the mask binary number.
[0094] The specific value of the number of bits can be set according to actual needs, and this embodiment does not impose any restrictions on it. The number of bits can be an even number, specifically a power of 2, such as 64 bits, 128 bits, etc.
[0095] For example, if the set bit length is 64 bits, and the initial reference binary number obtained from the reference number has 34 bits, then 30 zeros are added before the first digit of the initial reference binary number to obtain a 64-bit reference binary number. The first 32 bits of the mask binary number are all 0s, and the last 32 bits are all 1s. A bitwise AND operation is performed between the 64-bit reference binary number and the 64-bit mask binary number. The resulting first binary number has the first 32 bits all 0s, and the last 32 bits are the last 32 bits of the reference binary number.
[0096] After obtaining the first binary number, since the first binary number is a binary number, it is then converted into a decimal number, and the decimal number corresponding to the first binary number is used as the second reference sub-object.
[0097] For the process of converting binary numbers to decimal numbers, any applicable method can be selected based on practical experience.
[0098] For example, you can iterate through each bit of the binary number from right to left, multiply it by the corresponding power of 2 (starting from 0), and then add it to the result.
[0099] Suppose we have a binary number b n b n-1 ...b1b0, where b n b0 is the most significant bit (leftmost bit), and b0 is the least significant bit (rightmost bit). Multiply the rightmost bit (b0) by 2. 0 The next bit (b1) is multiplied by 2 1 And so on, until the highest bit (b) n Multiply by 2 n Finally, by adding all the products together, you can obtain the decimal number corresponding to the binary number.
[0100] In one optional implementation, the process of converting a reference number into N reference sub-objects in advance according to the target conversion method may include: performing a first calculation on the reference number to obtain a first reference sub-object, performing a second calculation on the reference number to obtain a second reference sub-object, and performing a third calculation on the reference number to obtain a third reference sub-object; and determining the first reference sub-object, the second reference sub-object, and the third reference sub-object as the N reference sub-objects.
[0101] For example, the process of performing a third calculation on the reference number to obtain a third reference sub-object may include: converting the reference number into a reference binary number of a set number of bits, shifting the reference binary number right by m bits to obtain a second binary number, and using the decimal number corresponding to the second binary number as the third reference sub-object. Here, m is half of the set number of bits.
[0102] The process of converting the reference number into a reference binary number of a set number of bits can be referred to the relevant description above, and will not be discussed in detail here.
[0103] The process of right-shifting the reference binary number by m bits involves deleting the last m bits of the reference binary number and padding the first digit of the reference binary number with m zeros. Therefore, the second binary number obtained by right-shifting the reference binary number by m bits has the first m bits as 0s and the last m bits as the first m bits of the reference binary number.
[0104] For example, if the set bit length is 64 bits, and the initial reference binary number obtained from the reference number has 34 bits, then 30 zeros are added before the first digit of the initial reference binary number to obtain a 64-bit reference binary number. The 64-bit reference binary number is then right-shifted by 32 bits, resulting in a second binary number where the first 32 bits are all 0s, and the last 32 bits are the first 32 bits of the original reference binary number.
[0105] After obtaining the second binary number, since it is a binary number, it is then converted to a decimal number, and the corresponding decimal number is used as the third reference sub-object. The specific conversion process can be found in the description above, and will not be discussed in detail here.
[0106] After converting the reference number into N reference sub-objects, for each reference sub-object, the reference sub-object is mapped and stored in bitmap data.
[0107] Bitmap data is a data structure that represents a dense set in a finite field, where each element appears at least once and is not associated with any other data. Bitmap data is a compact data structure used to represent the state (presence or absence) of elements in a fixed-size set or sequence. It uses a bit array to represent the state of elements in the set, with each element corresponding to one bit, thus achieving high space and time performance.
[0108] In this embodiment of the application, bitmap data that can meet storage requirements is set. The bitmap data contains multiple bits, each bit having its own corresponding position index. The initial value of each bit in the bitmap data is a first value indicating non-existence.
[0109] For example, the process of mapping and storing the reference sub-object in bitmap data may include: using the reference sub-object as a reference position index in the bitmap data, and setting the value of the bit corresponding to the reference position index in the bitmap data to a second value indicating its existence. It should be noted that the reference position index is the position index corresponding to the bit in the bitmap data; in this embodiment, it is referred to as the reference position index for ease of distinction.
[0110] For example, if the reference sub-object is 1561, then the bit in the bitmap data with position index 1561 is set to a second value indicating its existence.
[0111] The specific forms of the first and second values can be set according to actual needs, and this embodiment does not impose any restrictions on them. For example, the first value can be set to 0, the second value to 1, and so on.
[0112] Step 102: After obtaining the target number, the target number is converted into N target sub-objects according to the target conversion method. For each target sub-object, the existence of the target sub-object is queried from the bitmap data to obtain the query result of the target sub-object.
[0113] In this embodiment, call requests are monitored. Upon detection, the call request can be temporarily blocked, and the target number can be obtained from the call request. The target number refers to the number from which it needs to be determined whether to block it.
[0114] In this embodiment, a target sub-object refers to a sub-object derived from a target number. The target sub-object can be a calculated value derived from the target number, or it can be a portion of the extracted target number. The number of target sub-objects derived from a target number is the same as the number of reference sub-objects derived from a reference number.
[0115] In one optional implementation, the process of converting the target number into N target sub-objects according to the target conversion method may include: performing the first calculation on the target number to obtain a first target sub-object, performing the second calculation on the target number to obtain a second target sub-object, and determining the first target sub-object and the second target sub-object as the N target sub-objects. The first calculation is the same as the first calculation in the process of performing the first calculation on the reference number described above, and the second calculation is the same as the second calculation in the process of performing the second calculation on the reference number described above.
[0116] In one optional implementation, the process of converting the target number into N target sub-objects according to the target conversion method may include: performing a first calculation on the target number to obtain a first target sub-object, performing a second calculation on the target number to obtain a second target sub-object, and performing the third calculation on the target number to obtain a third target sub-object; and determining the first target sub-object, the second target sub-object, and the third target sub-object as the N target sub-objects. Wherein, the first calculation is the same as the first calculation in the process of performing a first calculation on the reference number, the second calculation is the same as the second calculation in the process of performing a second calculation on the reference number, and the third calculation is the same as the second calculation in the process of performing a third calculation on the reference number.
[0117] For example, the process of performing a first calculation on the target number to obtain a first target sub-object may include: dividing the target number by the preset value to obtain a target quotient, and using the integer part of the target quotient as the first target sub-object. The preset value is the same as the preset value used in the process of performing a first calculation on the reference number to obtain a first reference sub-object described above.
[0118] For example, the process of performing a second calculation on the target number to obtain a second target sub-object may include: converting the target number into a target binary number of a set number of bits, performing a bitwise AND operation between the target binary number and a mask binary number of the set number of bits to obtain a third binary number, and using the decimal number corresponding to the third binary number as the second target sub-object. Wherein, the set number of bits is the same as the set number of bits used in the process of performing a second calculation on the reference number to obtain a second reference sub-object, the first m bits of the mask binary number are 0, the last m bits are 1, and m is half of the set number of bits.
[0119] For example, the process of performing a third calculation on the target number to obtain a third target sub-object may include: converting the target number into a target binary number of a set number of bits, shifting the target binary number right by m bits to obtain a fourth binary number, and using the decimal number corresponding to the fourth binary number as the third target sub-object. Here, the set number of bits is the same as the set number of bits used in the process of performing a third calculation on the reference number to obtain a third reference sub-object, and m is half of the set number of bits.
[0120] After converting the target number into N target sub-objects, for each target sub-object, query the bitmap data to see if the target sub-object exists, and obtain the query result of the target sub-object.
[0121] For example, the process of querying whether the target sub-object exists in the bitmap data and obtaining the query result of the target sub-object may include: using the target sub-object as the target position index of the target sub-object in the bitmap data, and using the value of the corresponding bit of the target position index in the bitmap data as the query result of the target sub-object.
[0122] The query result for the target sub-object indicates whether the target sub-object exists in the bitmap data. When the query result for the target sub-object is a first value indicating non-existence (e.g., 0), it means that the target sub-object does not exist in the bitmap data; when the query result for the target sub-object is a second value indicating existence (e.g., 1), it means that the target sub-object exists in the bitmap data.
[0123] For example, if the target sub-object is 1561, then the value of the bit with position index 1561 in the bitmap data will be used as the query result of the target sub-object.
[0124] In one optional implementation, the number of bitmap data can be N, that is, the number of bitmap data is the same as the number of reference sub-objects converted from a reference number, and each reference sub-object converted from a reference number corresponds to one bitmap data. At the same time, the number of bitmap data is the same as the number of target sub-objects converted from a target number, and each target sub-object converted from a target number corresponds to one bitmap data.
[0125] For example, the process of mapping and storing the reference sub-object into bitmap data may include: mapping and storing the reference sub-object into the bitmap data corresponding to the reference sub-object.
[0126] For example, the process of querying whether the target sub-object exists in the bitmap data and obtaining the query result of the target sub-object may include: querying whether the target sub-object exists in the bitmap data corresponding to the target sub-object and obtaining the query result of the target sub-object.
[0127] Reference Figure 2 This diagram illustrates a bitmap data according to an embodiment of this application. Figure 2 As shown, it contains bitmap data 1, bitmap data 2, and bitmap data 3. Each bit in each bitmap data has its own position index (e.g., ...). Figure 2 The reference number is represented by 00000001, 00000002, 00000003, etc., where each bit has a value of 0 (indicating non-existence) or 1 (indicating presence). After converting the reference number into three sub-objects, each sub-object is mapped and stored in its corresponding bitmap data. After converting the target number into three target sub-objects, the existence of the target sub-object is checked in the bitmap data corresponding to each sub-object.
[0128] For the specific mapping, storage, and query process, please refer to the relevant description above. This embodiment will not elaborate further here.
[0129] By setting up multiple bitmap data sets and storing different types of reference sub-objects separately, the amount of data in each bitmap data set can be reduced, thereby improving the efficiency of mapping storage and querying.
[0130] In one optional implementation, the reference number can be a mobile phone number. Accordingly, before the step of converting the target number into multiple target sub-objects according to the target conversion method after obtaining the target number, the method may further include: after obtaining the user number in the call request, if it is determined that the user number is a mobile phone number, then the user number is used as the target number; if it is determined that the user number is not a mobile phone number, then the user number is not used as the target number. Therefore, the process of converting the target number into multiple target sub-objects according to the target conversion method after obtaining the target number is not executed, and thus the user number in the call request can be avoided.
[0131] The specific process for determining whether a user's number is a mobile phone number can be handled using any applicable method based on practical experience; this embodiment does not impose any restrictions on this. For example, the characteristics of a mobile phone number, such as the number of digits or the fact that each digit is a number, can be used to determine whether the user's number matches the characteristics of a mobile phone number. If it does, the user's number is determined to be a mobile phone number; otherwise, it is determined not to be a mobile phone number.
[0132] Step 103: Based on the query results of the N target sub-objects, determine whether the target number needs to be intercepted. If so, intercept the target number.
[0133] In one optional implementation, the process of determining whether to intercept the target number based on the query results of the N target sub-objects may include: when the reference number is a number that needs to be intercepted, if all the query results of the N target sub-objects exist, then it is determined that the target number needs to be intercepted; when the reference number is a number that does not need to be intercepted, if at least one of the query results of the N target sub-objects does not exist, then it is determined that the target number needs to be intercepted.
[0134] Specifically, if all N target sub-objects have a query result indicating that they exist, it means that the target number exists in the bitmap data; if at least one of the N target sub-objects has a query result indicating that they do not exist, it means that the target number does not exist in the bitmap data.
[0135] For example, the first value representing non-existence is set to 0, and the first value representing existence is set to 1. The target number is converted into a first target sub-object, a second target sub-object, and a third target sub-object. If the query results of the first target sub-object, the second target sub-object, and the third target sub-object are all 1, then it can be considered that the target number exists in the bitmap data; otherwise, it is considered that the target number does not exist in the bitmap data.
[0136] If it is determined that the target number needs to be blocked, then the target number can be blocked, and the specific blocking method can be handled based on practical experience. If it is determined that the target number does not need to be blocked, then the target number is not blocked, and the call request is forwarded to the next destination (such as forwarding it to the called user, etc.).
[0137] In this embodiment, a bitmap data mapping is used to store reference sub-objects converted from reference numbers. A query is performed based on the bitmap data to determine if a target sub-object converted from a target number exists. The query result for the target sub-object is then used to determine whether the target number needs to be intercepted; if so, the target number is intercepted. Since each reference sub-object can be mapped to a bit in the bitmap data, this method saves a significant amount of storage space compared to storing the entire reference number. Furthermore, the query operation in bitmap data involves simple read operations on individual bits, resulting in faster query speeds. This improves the efficiency of number interception and enhances the performance of the number interception device.
[0138] Reference Figure 3 The diagram shows a flowchart of a number interception method according to an embodiment of this application.
[0139] like Figure 3 As shown, number blocking methods may include:
[0140] The reference number (specifically a mobile phone number) is transformed to obtain N reference sub-objects, and bitmap data is generated based on the reference sub-objects. This process corresponds to step 101 above.
[0141] Access authentication is performed to obtain the user's number from the call request.
[0142] Determine if the user's number is a mobile phone number. If yes, proceed to the next step; otherwise, authentication fails.
[0143] The user's number is used as the target number, and the target number is transformed to obtain N target sub-objects.
[0144] Match N target sub-objects with bitmap data.
[0145] Determine if all N target sub-objects exist in the bitmap data. If yes, authentication passes; otherwise, authentication fails.
[0146] Successful authentication indicates that the target number exists in the bitmap data, while unsuccessful authentication indicates that the target number does not exist in the bitmap data.
[0147] In this embodiment of the application, by converting the number into multiple sub-objects for processing, the application scenarios are more extensive and are not limited by the number of digits.
