[0002] In related technologies, phone number attribution information can be obtained from the first 7 digits of a phone number, revealing the mobile operator and the province / city / region where the number is located. However, with the implementation of number portability, many users have changed their phone numbers' operators, rendering the previous method of querying number attribution information based on a fixed 7-digit code ineffective.

Detailed Implementation

[0018] 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.

[0019] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0020] See Figure 1 , Figure 1 This is a flowchart illustrating the blockchain-based number storage method provided in an embodiment of this application. Figure 1As shown, a blockchain-based number storage method may include the following steps: Step 101: Obtain multiple numbers and multiple number information that need to be stored. The multiple number information corresponds one-to-one with the multiple numbers. The number information includes the number portability data of the corresponding number between multiple operators.

[0021] In this embodiment, each number corresponds to a number information, which includes the number portability data of the corresponding number among multiple operators. Specifically, number portability data refers to the relevant data in the mobile communication industry on how a user transfers their mobile phone number from one operator to another without changing their phone number.

[0022] It should be noted that multiple numbers and information can be obtained by querying data from multiple operators. For example, if a number belongs to operator XX, a query request can be sent to operator XX's server to obtain the number and its corresponding information.

[0023] Optionally, the number portability data includes at least one of the following: the number portability history of the corresponding number, the outgoing operator of the corresponding number, the incoming operator of the corresponding number, the ownership information of the corresponding number, and the time information of the most recent number portability.

[0024] Specifically, each operator periodically or in real time extracts the mobile phone numbers of users who have performed number portability operations. The extracted information includes: the number portability history of the mobile phone number; the operator data of the first number porting out and the number porting in; the current number's ownership information and the timestamp of the most recent number portability.

[0025] Step 102: Store the multiple numbers in the main chain of the blockchain and store the information of the multiple numbers in multiple side chains of the blockchain. The main chain of the blockchain is connected to the multiple side chains, and the blockchain is managed by the multiple operators.

[0026] In this embodiment, the main chain and sidechains are two different blockchain structures. The main chain is the core of the blockchain network, carrying the network's core functions and major transaction records. It is the foundation of the blockchain and the initially created blockchain. Sidechains are blockchains relatively independent of the main chain, capable of bidirectional connections and asset transfers with the main chain. They are primarily used to extend the functionality of the main chain and provide different features. In other words, the main chain is the core of the blockchain network, providing the foundation for security and decentralization, while sidechains provide scalability and flexibility, enabling different applications and functions through interaction with the main chain.

[0027] By storing multiple numbers in the main chain of the blockchain and storing multiple number information in multiple side chains of the blockchain, the security of number and number information storage is improved.

[0028] Step 103: In the blockchain, synchronize the multiple numbers and the information of the multiple numbers to the nodes corresponding to the multiple operators.

[0029] In this embodiment, once the sidechain data is generated, the system broadcasts the complete sidechain to the entire blockchain network, ensuring that the data of all operators' corresponding nodes in the blockchain remains synchronized. The nodes corresponding to multiple operators can be one or more nodes; this embodiment does not impose a specific limitation. The initial blockchain structure is automatically generated and data synchronization is completed through blockchain technology. Smart contracts and automated initialization processes not only simplify the operators' operational steps but also ensure data consistency and accuracy. Leveraging the automation characteristics of blockchain, large-scale data initialization and synchronization can be completed quickly, effectively solving the problems of high complexity and cumbersome operation processes in traditional systems.

[0030] The technical solution of this application, after obtaining multiple numbers and multiple number information that need to be stored, stores the numbers in the main chain of the blockchain and stores the multiple number information in multiple side chains of the blockchain according to the multiple number information. After storage is completed, the multiple numbers and the multiple number information are synchronized to the nodes corresponding to the multiple operators. By using the blockchain to store multiple numbers and multiple number information, the stability and security of the numbers during storage are improved.

[0031] In some feasible implementations, optionally, obtaining the multiple numbers and multiple number information to be stored includes: Retrieve multiple numbers that need to be stored; Information is queried on the multiple servers corresponding to the multiple operators to determine the number information corresponding to each number, thereby obtaining multiple initial number information; The multiple initial number information is generated after security and integrity verifications are performed on each of the initial number information.

[0032] In this embodiment, information is queried on the collected numbers across multiple servers corresponding to each operator. This process involves accessing different databases or APIs to obtain relevant information for each number (such as user registration information, account status, etc.).

[0033] By querying, the system will obtain information on several initial phone numbers. Specifically, the query will retrieve basic data related to the number. For example, this data may include the number's location, account opening date, account status, and service plan information.

[0034] After obtaining the initial number information, the system needs to perform security and integrity verification on this information to ensure the authenticity and tamper-proof nature of the data. Security verification ensures that the data has not been tampered with or leaked by unauthorized operations, and may involve methods such as encryption and authentication. Integrity verification ensures that the data has not been modified during transmission and storage and accurately represents the original information, for example, by using methods such as hash algorithms.

[0035] With both security and integrity verifications passed, the system ultimately generated multiple valid number information entries.

[0036] Optionally, storing the plurality of numbers in the main chain of the blockchain and storing the plurality of number information in multiple side chains of the blockchain includes: The blockchain is initialized. If the number information corresponding to the target number indicates that the number portability count of the target number is less than or equal to 1, the hash value corresponding to the target number is stored in the main chain of the blockchain, and the number information corresponding to the target number is stored in a side chain connected to the main chain, wherein the target number is any one of the plurality of numbers; If the number information corresponding to the target number indicates that the number portability count of the target number is greater than 1, the hash value corresponding to the target number is stored in the main chain of the blockchain, and the number information corresponding to the target number is stored in N sequentially connected side chains, where N is the number portability count of the target number, and the first side chain among the N sequentially connected side chains is connected to the main chain.

[0037] In this embodiment, the existing historical number portability data is first initialized on a blockchain, with the main blockchain created by the original operator. Then, after the outgoing and incoming operators confirm the historical data is correct, block 0 of the sidechain is generated. Subsequent portability operations sequentially generate new sidechain blocks until the current operator is confirmed. To ensure the integrity and immutability of the data initialization process, a timestamp server is introduced to timestamp each initialization operation, ensuring the correct order of historical data. The incoming operator checks each number to determine if there are any subsequent portability operations. If so, block 1 is generated, until all portability operations are completed.

[0038] In this embodiment, the blockchain consists of a main chain and multiple side chains, used to record the historical number portability operations for each number. The main chain blocks record the hash value of the user's mobile number to ensure user privacy; these blocks are generated by the operator network through a consensus mechanism, avoiding the generation process of blocks controlled by a single operator. The side chains are responsible for storing specific number portability records. Block 0 stores the initial number portability operation data, and each subsequent portability generates a new block, recording the portability time, the sending / receiving operator information, and the digital signatures of both parties. Furthermore, in this application, each block in the main chain can automatically trigger updates to the side chains via smart contracts, ensuring that portability records are written in real time. A layered storage strategy is adopted, storing the most frequently accessed latest portability records in a high-efficiency storage layer, while historical records are stored in a cold storage layer, improving access efficiency.

[0039] The memory structure for one-time transfer and two-time transfer is as follows: Figure 2 , Figure 3 As shown, Figure 2 This is one of the schematic diagrams of the blockchain structure of this invention. Figure 3 This is the second schematic diagram of the blockchain structure of this invention. The main chain blocks contain the hash values ​​of the mobile phone numbers of users porting their numbers. The blocks of the attached side chains correspond to each porting record. Each main chain block has a corresponding side chain attached. Block 0 of the side chain records the first porting operation for that mobile phone number, including the first porting time, the porting-out operator's information, the porting-out operator's digital signature, the porting-in operator's information, and the porting-in operator's signature data. Block 1 records the second porting operation, similarly including the porting time, the porting-out operator's information, the porting-out operator's digital signature, the porting-in operator's information, and the porting-in operator's signature data. Blocks 2, 3, and so on, store the records of the third and fourth porting operations. The information stored in the block with the highest block number is the latest number porting information for that mobile phone number.

[0040] The main chain records the hash value of each user's mobile phone number in each block to ensure user privacy. The main chain is generated using a decentralized consensus mechanism, avoiding the risk of data control by a single operator. Sidechains record the detailed number portability history of each mobile phone number; a new block is generated and relevant information is recorded for each portability operation. The advantage of this structure is that it leverages the decentralized nature of blockchain to achieve data security, immutability, and transparency, while providing more efficient access performance.

[0041] Optionally, synchronizing the multiple numbers and their information to the nodes corresponding to the multiple operators in the blockchain includes: Generate synchronization information, which indicates that the storage of the plurality of numbers and the information of the plurality of numbers has been completed in the blockchain; The synchronization information is broadcast to the nodes corresponding to the multiple operators.

[0042] Specifically, after storing multiple numbers and their information in the blockchain, synchronization information is generated and broadcast to the multiple operators, thereby ensuring that the multiple operators can always maintain data synchronization.

[0043] Each number portability operation requires confirmation from both the sending and receiving operators, and both parties must record the information in the sidechain block using digital signatures. This multi-party consensus mechanism effectively prevents disputes or errors that might arise from unilateral data manipulation, making the data confirmation process more transparent and fair. Furthermore, this mechanism reduces the possibility of human error and enhances the data's tamper-proof capabilities through digital signatures.

[0044] Optionally, after synchronizing the plurality of numbers and the plurality of number information to the nodes corresponding to the plurality of operators in the blockchain, the method further includes: A first permission is assigned to the user terminal, which is used to query the multiple numbers in the blockchain. The user terminal is the user terminal that requests to query information in the blockchain. A second permission is assigned to the multiple operators, the second permission being used to query the multiple numbers and the multiple number information in the blockchain.

[0045] In this embodiment, once the blockchain is initialized, it can provide services to the outside world. Specifically, users can use the first permission, meaning enterprise users can join the blockchain network and become nodes or light nodes to access and synchronize data. To ensure data security and privacy, enterprise users can only access data within their authorized scope and maintain the synchronization of number attribution information by listening to broadcast updates on the blockchain. Multiple operators can use the second permission; enterprise users do not need to store all the data in the entire blockchain, but only need to obtain the number attribution information related to them, thereby achieving lightweight data management and updates.

[0046] It's important to clarify that operators play a dual role in the blockchain: they are both builders and users. As builders, operators are responsible for adding and updating main chain blocks and side chain blocks in the blockchain. During number portability, the sending and receiving operators confirm relevant data through a multi-party consensus mechanism and generate new side chain blocks in the blockchain, recording each portability operation. The process of adding blocks requires digital signatures from both operators for confirmation, ensuring the legality and immutability of number portability. As users, operators are responsible for regularly synchronizing the latest number portability information through broadcast updates on the blockchain and providing this information to enterprise users through their own systems, ensuring data real-time performance and consistency.

[0047] To ensure the consistency of number portability data across operators, the blockchain system employs a network-wide broadcast and consensus mechanism, enabling all operator nodes to maintain synchronized data updates. After each number portability operation is completed, a new block is generated and broadcast through the blockchain network. All participating operator nodes receive the latest number attribution information and synchronize their own data copies. If a node of one operator fails, other operators can still continue to provide query and synchronization services, ensuring high availability and fault tolerance of the system.

[0048] The technical solution of this application, after obtaining multiple numbers and multiple number information that need to be stored, stores the numbers in the main chain of the blockchain and stores the multiple number information in multiple side chains of the blockchain according to the multiple number information. After storage is completed, the multiple numbers and the multiple number information are synchronized to the nodes corresponding to the multiple operators. By using the blockchain to store multiple numbers and multiple number information, the stability and security of the numbers during storage are improved.
