Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the method for forwarding group number portability based on blockchain and the system for forwarding group number portability based on blockchain of the present invention are further described in detail below with reference to the accompanying drawings and the detailed description.
The invention provides a block chain-based group number portability method, as shown in figure 1, comprising the steps of:
step S1): and the user registers in the block chain, inquires the work and credit department node of the block chain and obtains the address of the work and credit department node.
The block chain at least comprises a business communication department node and a plurality of service control point nodes of operators. In this step, for example, a user with the cell phone number 18601102222 of Unicom registers a user node A in the blockchain, and when the user first accesses the blockchain, the user node A operator queries the information of the created block and extracts the address of the Ministry of industry and once the information of the created block is queried and the corresponding address is extracted, the information can be stored in the local blockbook for later use.
As shown in fig. 2, the step of the user node a operator user inquiring information of the created block and extracting an address of the work and trust department node includes:
step S11): the user node A broadcasts the query request information of the user node A to the block chain, the query request information comprises the identity information, the mobile phone number, the public key and other information of the user node A, and the query request information is broadcasted to the block chain after being signed by the private key of the node. When the user node a queries the created blocks of the block chain to its own neighboring nodes, the user node a may query the created blocks to its own neighboring nodes, and then compare the received created blocks to determine whether they are consistent, and if so, the user node a regards them as real created blocks. If not, it is true to define a created block that exceeds a certain number percentage threshold, since the existence of any blockchain assumes that most of the blockchains are good;
step S12): the user node A inquires the created blocks of the block chain from the adjacent nodes of the user node A, and the inquiry request is signed by using the private key of the user node A and then is sent to each adjacent node;
step S13): the user node A receives the created block returned from the adjacent node and subjected to correctness verification, the created block is stored in the local of the user node A, and the address of the originator node of the block chain, namely the address of the Ministry of industry and communications node, is taken out from the created block.
Step S2): the user node inquires the current latest operator list from the business and information department node of the block chain, and sends a message to be forwarded with the number to the block chain, wherein the message to be forwarded with the number at least comprises the operator to which the terminal number of the user node is forwarded with the number, and the block chain at least comprises the business and information department node and the service control point nodes of a plurality of operators.
In this step, when the user node a queries the current and latest operator list from the carrier node of the blockchain and sends the message to be ported to the blockchain, as shown in fig. 3, the method includes:
step S21): the user node A inquires the address of the business and information department node of the block chain, and requests the business and information department node to inquire the operator list of the block chain according to the address of the business and information department node, and the inquiry information is signed by using the private key of the user node A;
step S22): the business and information department node receives the inquiry information of the user node A, replies the current latest operator list of the block chain to the user node A, and the reply information is signed by using the private key of the business and information department node and then is sent to the user node A;
step S23): after receiving the latest operator list, the user node a selects an operator to be ported in with the number according to the operator information in the list, and broadcasts a message to be ported in with the number to a block chain, wherein the message to be ported in with the number at least comprises: the identity and the public key of the user node A, the identifier of a new operator to be carried in the network, and the network information to be carried in the network is signed by the private key of the user node A and then is broadcasted to the block chain.
Step S3): and the service control point node of the current home operator corresponding to the terminal number receives the network forwarding message to be number-portability and confirms whether the terminal number is a group number.
In this step, after receiving 18601102222 the broadcast message of number portability, a certain connected service control point node inquires its internal group number list to determine whether the user node a is a group user. The group number, that is, the terminal number information of a plurality of accounts of the group user is stored in the service control point node of the operator. In this step, the service control point nodes of the operators at least include at least two of a unicom service control point node, a telecommunication service control point node, and a mobile service control point node, and the office node and the service control point node of each operator have an identifier, a public key, and a private key.
Step S4): if the terminal number is a group number, the service control point node of the current home operator corresponding to the terminal number broadcasts group attribute information of the terminal number, the group attribute information at least comprises a long number-group short number corresponding relation list of the terminal number and a current home operator identifier, and the group attribute information is signed by using a private key of the service control point node of the current home operator.
In this step, if a certain connected service control point node is queried and finds that the number 18601102222 belongs to a certain group number, the information that the number 18601102222 belongs to the group number is broadcasted. That is, if the terminal number is a group number, the call and data Network service can be traced in the communication process by the long number-group short number correspondence list of the terminal number and the tracking of the current home operator identifier, and an internal charging mode of a Virtual Private Network (VPN) of the group is implemented, so that the group number can be ensured to normally obtain the call and data Network service provided by the operator after the operator is changed, and the group number can enjoy the preference of group package.
Step S5): and the service control point nodes of other operators except the current home operator corresponding to the terminal number receive the group attribute information, verify whether the signature of the group attribute information is correct, record the group attribute information if the signature of the group attribute information is correct, and complete number portability of the terminal number.
In this step, the group attribute information at each number portability is recorded in the account book of the service control point node of each operator, and the long number-group short number correspondence of the terminal number of the user node a and the tracking of the home operator are provided. Therefore, in the multi-number portability, the account book of the service control point node of each operator sequentially records the number portability information of the user node A, continuously tracks the corresponding relation of the long number and the group short number of the terminal number and the home operator, and ensures that the group service can be normally used after the terminal number is ported out. Preferably, an additional number identifier is added to the long number-group short number of the terminal number, and the additional number identifier is used for distinguishing different long numbers corresponding to group short numbers with the same value.
In this embodiment, after receiving the broadcast message, the service control point node of each operator records the content of the broadcast message whose signature is verified to be correct. The broadcast record is mainly used for tracking and recording the corresponding relation between the long number and the short number of the group number and the attribution of an operator if the group number of the second or more than second number portability needs to be used and the calling mode of the group short number is still used; in order to avoid duplication between a certain carried-in short number and the previous short number of the operator, a number identifier is attached to the long number-group short number of each carried-out terminal number to distinguish different long numbers corresponding to the same short number, so that the latest communication access network capable of tracing back to the terminal number is always maintained.
It should be understood that, as shown in fig. 4, before the user node a sends the message to be ported to the blockchain, a preprocessing procedure is further included, which includes steps of building the blockchain and admitting the service control point node of the operator, including:
step S01) creating a block of the block chain established by the Gongsu node, wherein the creating block comprises the ID of the Gongsu node, the public key and the record information of the identity information of the originator, and the record information is signed by using the private key of the Gongsu node.
In this step, the industrial and telecommunications department node issues a created block of the local block chain in the block chain by using a broadcast message as an originator of the local block chain, wherein the created block includes the following contents: the identity and public key of the Ministry of industry and trust node and identity information of the originator. The broadcast message is signed by the private key of the Ministry of industry and information node and then is broadcast to the block chain, and the created block is used as the first block of the block chain.
In the service control point node of the operator, the information such as the long number-group short number corresponding relation list of the terminal number belonging to the operator, the identifier of the current belonging operator and the like is prestored.
Step S02) the operator user inquires information of the created block and extracts the address of the work and letter department node.
In this step, the operator user, for example, node B, queries its neighboring node for the created block of the block chain, and sends the query request after signing with the private key of node B.
Step S03) the operator user sends application information to the business department node to apply for becoming the business control point node of the operator, the application information includes the self identification, public key and identity information of the registered node, and uses the private key of the registered node to sign, the identity information at least includes the company name, legal representative, registered capital, registered address, enterprise registration number and establishment time of the operator user.
In this step, the operator user sends an application request to the carrier service control point node, where the application request includes the blockchain identifier and the public key of the node B, the company name, legal representative (name + identification number), registered capital, registered address, enterprise registration number (registration number such as 569876654324567), and establishment time of the node B.
Step S04), the Ministry of industry and information department node receives the application of the registered node, checks the operator qualification of the operator user and the record information of the corresponding operator user obtained through the non-block chain way, and judges whether the registered node has the operator qualification.
In the step, the node of the business and the letter department receives the application request of the node B for becoming the service control point node of the operator of the block chain, the operator qualification of the node B is checked, if the check is passed, the basic information reported to the operator in advance by each operator obtained by the non-block chain way in the business and the letter department node of the node B is checked, and the basic information comprises the identification and the public key of the block chain of the service control point node of the operator, the identification and the public key of the home location register and the like.
Step S05), the industrial and telecommunications department node uses the private key signature of the industrial and telecommunications department node to broadcast the attribute information of the registered node which passes the qualification audit of the operator to the block chain to declare the registered node to become the service control point node of the operator, and the attribute information comprises the identifier and the public key of the registered node.
In this step, if all the audits are passed, the Ministry of industry and communications node sends a broadcast message to the blockchain, declares that the node B becomes a service control point node of an operator of the blockchain, and broadcasts the broadcast message after being signed by a private key of the Ministry of industry and communications node.
Step S06) the carrier node stores the attribute information of the service control point nodes of all the operators in the local list.
In this step, the irc node adds the information about the node B to the list information of the service control point node of the operator stored in its own home.
Based on the created block, before the operator user sends the application information application to the Ministry of industry and information node for the first time to become the service control point node of the operator, the method also comprises the step that the operator user confirms the Ministry of industry and information node and the authenticity qualification thereof in the block chain, and comprises the following steps:
step S07) the operator user broadcasts notification information to the blockchain, wherein the notification information comprises the self identification, the public key and the identity information of the registered node, and the private key of the registered node is used for signature.
In this step, when a node B wants to apply for a service control point node of an operator of the local blockchain, the node first broadcasts its identity information to the blockchain when the node B first accesses the blockchain, the broadcast message includes information such as the service control point node identity information, an identifier, and a public key of the operator of the node B, and the broadcast message is signed by using a private key of the node and then broadcast to the blockchain.
Step S08) the registered node sends query information for the founding block to at least one neighboring node of the block chain, the query information being signed using the private key of the functional node.
In this step, the node B queries its own neighbor node for the created block of the block chain, and the query request is signed by using the private key of the node B and then sent to each neighbor node. The node B may perform a discovery block query to its neighboring nodes.
Step S09) the registration node confirms the authenticity of the created block of the block chain by the authenticity information of the created block returned by the adjacent node or the percentage of the authenticity information of the created block returned by two or more adjacent nodes.
In this step, the node B compares whether the received created blocks are consistent, and if so, the created blocks are considered to be real created blocks; if not, since the existence of any blockchain assumes that most of the blockchains are good, it can be determined whether the returned information is a real created block by defining whether the returned information has consistency exceeding a certain number percentage threshold. And the node B receives the created block returned from the adjacent node and subjected to correctness verification, stores the created block information in the local of the node B, and takes the address of the originator node of the block chain, namely the address of the Ministry of industry and communications node from the created block information.
