Optionally, the blockchain network is a peer-to-peer network.
The invention provides a number portability calling method, which aims to solve the technical problems in the prior art.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a number portability calling method according to an embodiment of the present invention. The embodiment of the invention provides a number portability calling method aiming at the technical problems in the prior art, which comprises the following specific steps:
In this embodiment, as shown in fig. 1, the user node 14 is originally a node belonging to a second operator, that is, the second operator provides a communication service for the user node 14, and when the user node 14 performs number portability in advance, the user node 14 sends a first broadcast message in the blockchain network, where the first broadcast message is used to indicate that the user node 14 applies for number portability, i.e., forwards the number portability from the second operator network.
Alternatively, the department of industry and telecommunication node 10, the first operator node 11, the second operator node 12, and the third operator node 13 shown in fig. 1 may be configured to receive the first broadcast message sent by the user node 14 as a mining node in the blockchain network, and store the first broadcast message locally. In addition, the first broadcast message may also be written to a new block in the blockchain network, i.e., the first broadcast message is written to a blockchain ledger.
When the second operator node 12 receives the first broadcast message sent by the user node 14, the second operator node 12 determines that the user node 14 belongs to the second operator according to the identification information of the user node 14. Optionally, the second operator node 12 locally stores user information of a user node belonging to the second operator, and since the first broadcast message is used to indicate that the user node 14 applies for number portability, that is, is ported out from the second operator network, the second operator node 12 deletes the user information of the user node 14 from the local, and performs suspension processing, charging settlement operation, and the like on the current service of the user node 14. In addition, the second operator node 12 also sends a second broadcast message in the blockchain network, optionally, the user node 14 is embodied as a mobile terminal such as a mobile phone, and the second broadcast message may include: a cell phone number of the user node 14, a message that the second operator node 12 and the user node 14 have released the contract, an identification and a public key of the second operator node 12, and the like. Optionally, the second broadcast message is signed by a private key of the second operator node 12 and then broadcast to the blockchain network.
When the second operator node 12 broadcasts the second broadcast message into the blockchain network, the first operator node 11 receives the second broadcast message and may determine from the second broadcast message that the second operator node 12 and the user node 14 have contracted.
After receiving the first broadcast message sent by the user node 14 and the second broadcast message sent by the second operator node 12, the first operator node 11 records the identification information of the user node 14, and pushes the detailed information of the service or package of the first operator to the user node 14, and optionally, the detailed information of the service or package is signed by using the private key of the first operator node 11 and then sent to the user node 14. After receiving the detailed information of the service or package pushed by the first operator node 11, the user node 14 selects one of the service packages, and signs an intelligent contract about the service package with the first operator node 11, optionally, the user node 14 signs the intelligent contract with its own private key and sends the intelligent contract to the first operator node 11, after receiving the intelligent contract, if it is determined that the intelligent contract is correct, the first operator node 11 signs the intelligent contract with its own private key for the second time, and thus, the intelligent contract is formally signed.
Step 204, the first operator node receives an account book query request sent by a call session control function entity.
As shown in fig. 1, the user node 15 is a node belonging to a first operator, and when the user node 15 calls the user node 14, the call session control function entity sends an account book query request to an operator node to which the user node 15 belongs, for example, the first operator node 11, where the account book query request is used to query identification information and province information of an operator to which the called end, i.e., the user node 14, currently belongs.
Since the first operator node 11 is a node in the blockchain network, the first operator node 11 locally stores a blockchain account book, and the blockchain account book stores identification information and province information of a user node, i.e., an operator to which the user terminal currently belongs, of the number portability. When the first operator node 11 receives the account book query request sent by the call session control function entity, query the local blockchain account book, determine that the user node 14 is a user node from the second operator to the first operator, and query and obtain the identification information and provincial information of the operator to which the user node 14 currently belongs from the blockchain account book.
The first operator node 11 sends the identification information and province information of the operator to which the user node 14 currently belongs to the user node 15, and a Gateway Mobile Switching Center (GMSC) of the first operator to which the user node 15 belongs transfers a call of the user node 15 to the user node 14 to the GMSC of the operator to which the user node 14 currently belongs.
According to the embodiment of the invention, the block chain network is formed by the business information part node and the plurality of operator nodes, when the user node needs number portability, the user node broadcasts the broadcast message of the number portability network to the block chain network, so that the business information part node and the plurality of operator nodes can both receive the broadcast message and carry out number portability for the user node according to the broadcast message.
Fig. 3 is a flowchart of a number portability calling method according to another embodiment of the present invention. On the basis of the foregoing embodiment, after the first operator node pushes the service information to the user node according to the first broadcast message and the second broadcast message, the method further includes the following steps:
Optionally, the user node 14 signs the smart contract with its own private key and sends the signed smart contract to the first operator node 11.
After the first operator node 11 receives the intelligent contract, if the intelligent contract is determined to be correct, the first operator node 11 performs secondary signature on the intelligent contract by using its own private key.
And step 303, the first operator node sends the intelligent contract signed again to the user node.
The first operator node 11 sends the twice signed smart contract to the user node 14.
According to the embodiment of the invention, the block chain network is formed by the business information part node and the plurality of operator nodes, when the user node needs number portability, the user node broadcasts the broadcast message of the number portability network to the block chain network, so that the business information part node and the plurality of operator nodes can both receive the broadcast message and carry out number portability for the user node according to the broadcast message.

In addition, the head office node may also update the list in real time.
When the first operator node wants to become the operator node in the block chain network where the business department node is located, the first operator node sends application information to the business department node, wherein the application information is used for indicating that the first operator node applies to become the operator node in the block chain network. Optionally, the application information includes information such as an identifier, a public key, a company name, a legal representative (name + identification number), a registered capital, a registered address, an enterprise registration number (registration number such as 569876654324567), and an establishment time corresponding to the first operator node.
When the business and information department node receives the application information sent by the first operator node, the business and information department node verifies the operator qualification of the first operator node, if the business and information department node passes the verification of the operator qualification of the first operator node, the business and information department node further verifies the locally stored basic information of each operator node, and optionally, the basic information of each operator node comprises the identification, the public key, the terminal equipment number and other information of each operator node; if the business and information department node also passes the verification of the stored basic information of each operator node, the business and information department node sends a broadcast message to the block link network, wherein the broadcast message may specifically include a verification result of the business and information department node on the operator qualification of the first operator node, and the verification result indicates that the business and information department node passes the operator qualification verification of the first operator node. Optionally, the work and trust department node uses its private key to sign the audit result and broadcasts the result to the blockchain network. Further, the carrier node adds information about the first operator node to a list stored locally at the carrier node.
According to the embodiment of the invention, the block chain network is formed by the business information part node and the plurality of operator nodes, when the user node needs number portability, the user node broadcasts the broadcast message of the number portability network to the block chain network, so that the business information part node and the plurality of operator nodes can both receive the broadcast message and carry out number portability for the user node according to the broadcast message.

Optionally, the work and information department node signs the broadcast message with its own private key, and broadcasts the signed broadcast message to the block chain network, and optionally, the created block is a first block of a block chain corresponding to the block chain network.
When the first operator node joins the blockchain network for the first time, information such as identity information, identification information and a public key of the first operator node is broadcasted in the blockchain network. Optionally, the first operator node encrypts information such as identity information, identification information, and a public key of the first operator node using its own private key, and broadcasts the encrypted information to the blockchain network.
Optionally, the first operator node queries its neighboring node for the created block in the blockchain network, for example, the first operator node sends a query request to its neighboring node, where the query request is used to query the created block in the blockchain network. Optionally, the first operator node signs the query request with its own private key and sends the signed query request to the neighboring nodes, where the number of the neighboring nodes is not limited, and may be multiple or one. If the number of the adjacent nodes of the first operator node is multiple, the first operator node receives the created blocks respectively sent by the multiple adjacent nodes, the created blocks respectively sent by the multiple adjacent nodes may be the same or different, and if the created blocks respectively sent by the multiple adjacent nodes are different, the first operator node determines that created blocks exceeding a certain number percentage threshold among the created blocks respectively sent by the multiple adjacent nodes are real; if the created blocks sent by the adjacent nodes are the same, the first operator node determines that the created blocks are real.
When the first operator node acquires a real created block from an adjacent node, the created block is stored locally, network address information of the Ministry of industry and communications node is acquired from the created block, and application information is sent to the Ministry of industry and communications node according to the network address information of the Ministry of industry and communications node.
And step 510, the first operator node sends the intelligent contract signed again to the user node.
