Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the current technical solution, after the user carries the number and changes the network, when a third-party operator (e.g., a bank, a hospital, etc.) sends information to the terminal, the information is still sent to the industry gateway of the change-out operator, so that the industry gateway of the change-out operator forwards the information to the terminal. However, the industry gateway of the operator can not send information to the terminal any more, so that the terminal cannot be correctly addressed, and the terminal fails to receive information.
In view of this, the present application provides a terminal addressing method, which is suitable for addressing a number portability terminal, so that a third-party operator can correctly address the terminal, thereby avoiding the number portability user from missing information reception, and improving the number portability experience of the user.
The application provides a terminal addressing method in a first aspect. Fig. 1 is a flowchart of a terminal addressing method according to an embodiment of the present application, where the method is applicable to a number portability server. As shown in fig. 1, the method comprises the steps of:
step S101, a first number portability request sent by a transfer-in operator is forwarded to a transfer-out operator.
The first number portability request comprises the compensation amount of the transfer-in operator to the transfer-out operator. The transfer-in operator is a communication operator to which the terminal is to be transferred through number portability, and the transfer-out operator is an attributive communication operator before the number portability of the terminal.
The number portability server is a server which can realize the terminal addressing method. In some embodiments, the number portability server is set by an authority (e.g., an industry and informatization department). In other embodiments, the number portability servers are co-located by the carriers. In practical application, the number portability server can be flexibly set according to specific requirements, and the application is not limited to this.
In some embodiments, when the transfer-in operator learns that the terminal has a transfer-in requirement of number portability, the transfer-in operator sends a first number portability request to the number portability server. The number portability server receives a first number portability request sent by the transfer-in operator, and forwards the first number portability request to the transfer-out operator, so that the transfer-out operator can obtain the compensation amount proposed by the transfer-in operator for the number portability of the terminal through the first number portability request.
It should be noted that, because the number portability server is authoritative, the number portability server obtains the approval of all communication operators. Therefore, whether the operator is transferred out or transferred in, the message sent by the number portability server is received, and the authenticity of the message is approved.
Step S102, receiving the number portability approval message returned by the transfer-out operator.
Wherein, the number portability approval message is a message returned under the condition that the remittance operator agrees the compensation amount.
In some embodiments, after receiving the first number portability request forwarded by the number portability server, the transfer-out operator obtains the compensation amount proposed by the transfer-in operator for the terminal number portability according to the first number portability request, and determines whether to approve the compensation amount. And under the condition that the transfer-out operator agrees to the compensation amount, the transfer-out operator generates a number portability approval message and sends the number portability approval message to the number portability server. And the number portability server receives the number portability approval message sent by the transfer-out operator.
It should be noted that, when the roll-out operator does not agree with the compensation amount proposed by the roll-in operator, the roll-out operator generates and sends a number portability rejection message to the number portability server. The number portability network transfer server forwards the number portability network transfer refusal message to the transfer-in operator, or generates and sends a number portability network transfer failure message to the transfer-in operator according to the number portability network transfer refusal message, and terminates execution of the number portability network transfer process. The number portability failure message may include a failure reason, so that the portability operator determines subsequent operations (for example, increasing the compensation amount or rejecting the number portability request of the terminal) according to the failure reason.
And step S103, generating and sending a number portability success message to the transfer-in operator so that the transfer-in operator can pay the reimbursement money to the transfer-out operator according to the reimbursement amount.
In some embodiments, the number portability server receives a number portability approval message sent by the transfer-out operator, learns the amount of compensation the transfer-out operator agrees to propose by the transfer-in operator, generates a number portability success message, and sends the number portability success message to the transfer-in operator. The transfer-in operator receives the successful number portability message sent by the number portability server, knows the reimbursement amount agreed by the transfer-out operator, and pays the reimbursement money to the transfer-out operator according to the reimbursement amount.
And step S104, addressing the terminal according to the communication number of the terminal in the terminal addressing request under the condition of receiving the terminal addressing request sent by the third-party operator.
Wherein the third party operator is other operators except the transfer-in operator and the transfer-out operator. For example, the third-party operators include banks, hospitals, e-commerce platforms, intermediary service platforms, and the like. In practical applications, the terminal addressing request may be generated by a server or other communication device of the third-party operator and sent to the number portability server.
In some embodiments, when the third-party operator addresses the terminal, the third-party operator generates a terminal addressing request according to the communication number of the terminal, and sends the terminal addressing request to the number portability server. The number portability network server receives the terminal addressing request, determines the transfer-in operator of the terminal according to the communication number of the terminal, and then addresses the terminal through the transfer-in operator. The communication number of the terminal includes, but is not limited to, a mobile phone number and a fixed phone number.
In the terminal addressing method provided by this embodiment, the number portability server forwards a first number portability request sent by the transfer-in operator to the transfer-out operator, where the first number portability request includes an amount of compensation of the transfer-in operator to the transfer-out operator; receiving a number portability approval message returned by the roll-out operator, wherein the number portability approval message is a message returned under the condition that the roll-out operator agrees to the compensation amount; generating and sending a number portability success message to the transfer-in operator so that the transfer-in operator can pay the reimbursement money to the transfer-out operator according to the reimbursement amount; under the condition of receiving a terminal addressing request sent by a third-party operator, the terminal is addressed according to the communication number of the terminal in the terminal addressing request, even if the operator does not timely and uniformly update the data of the number portability user, the third-party operator can address the terminal through the number portability server, the number portability user is prevented from missing receiving information, and the number portability experience of the user is improved.
Fig. 2 is a flowchart of a terminal addressing method according to a second embodiment of the present application, where the method is applicable to a number portability server. As shown in fig. 2, the method comprises the steps of:
step S201, a first number portability request sent by a portability operator is received.
Step S201 in this embodiment is the same as step S101 in the first embodiment of this application, and is not described herein again.
Step S202, receiving a network switching public key of the terminal sent by the switching operator.
The network transfer public key is a key set by the transfer operator for the terminal to carry the number and transfer the network. And corresponding to the network switching public key, the switching operator also sets a network switching private key for the terminal and sends the network switching private key to the terminal.
In some embodiments, the terminal sends a third number portability request to the portability operator. And after the transfer-in operator receives the third number portability request, setting a network transfer public key and a network transfer private key for the terminal number portability at this time, sending the network transfer public key to the number portability server, and sending the network transfer private key to the terminal through a preset channel. The preset channel is a communication channel with a higher security level, so that the leakage of the network switching private key is avoided.
In some specific implementations, the transit operator sets a communication number of the terminal as a transit public key, and generates a transit private key of the terminal based on a preset initial key, a public parameter and the transit public key of the terminal. In this specific implementation manner, the transit operator may not send the transit public key of the terminal to the number portability transit server, but may inform the number portability transit server of the setting manner of the transit public key in advance, so that the number portability transit server may directly use the communication number of the terminal as the transit public key of the terminal.
And step S203, verifying the signature of the first number portability request based on the network-forwarding public key of the terminal.
When the first number portability network forwarding request is a request signed by a network forwarding private key of the terminal, the number portability network forwarding server can verify the signature of the first number portability network forwarding request by using a network forwarding public key of the terminal. When the signature of the first number portability request passes the verification, the first number portability request is a request for obtaining the terminal approval; and when the signature of the first number portability request is not verified, the first number portability request is not approved by the terminal, and the number portability server terminates the subsequent flow.
And step S204, under the condition that the signature of the first number portability request passes the verification, forwarding the first number portability request to a transfer-out operator.
The signature of the first number portability request is verified, which indicates that the first number portability request is a request approved by the terminal, and the number portability server further forwards the first number portability request to the roll-out operator, so that the roll-out operator determines whether to agree with the compensation amount proposed by the roll-in operator for the terminal number portability.
Step S205, receiving the number portability approval message returned by the rollout operator.
Step S206, a number portability success message is generated and sent to the transfer-in operator, so that the transfer-in operator can pay the reimbursement money to the transfer-out operator according to the reimbursement amount.
And step S207, addressing the terminal according to the communication number of the terminal in the terminal addressing request under the condition of receiving the terminal addressing request sent by the third-party operator.
Steps S205 to S207 in this embodiment are the same as steps S102 to S104 in the first embodiment of the present application, and are not described again here.
The terminal addressing method provided by the embodiment comprises the steps that a transfer-in operator sets a network transfer public key and a network transfer private key for a terminal, the terminal uses the network transfer private key to sign a first number portability request, and a number portability server uses the network transfer public key to verify the signature of the first number portability request, so that the authenticity and the legality of the first number portability request are guaranteed, the potential safety hazard caused by counterfeiting the number portability request to a user is avoided, and the security of number portability is improved.
A second aspect of the present application provides a terminal addressing method. Fig. 3 is a flowchart of a terminal addressing method provided in the third embodiment of the present application, where the method is applicable to an operator server. As shown in fig. 3, the method comprises the steps of:
step S301, a first number portability request is sent to a preset number portability server.
The first number portability request comprises the compensation amount of the transfer-in operator to the transfer-out operator. The number portability server is a server which can realize the terminal addressing method.
In some embodiments, the number portability server is set by an authority (e.g., an industry and informatization department). In other embodiments, the number portability servers are co-located by the carriers. In practical application, the number portability server can be flexibly set according to specific requirements, and the application is not limited to this.
In some embodiments, when the transfer-in operator learns that the terminal has a transfer-in requirement of number portability, the transfer-in operator sends a first number portability request to the number portability server.
For example, the terminal user initiates a request for handling number portability service to the transfer-in operator in an online manner, or the terminal user line transfers the number portability service to the business hall of the operator, the transfer-in operator learns the transfer-in requirement of the number portability of the terminal, and sends a first number portability request to the number portability server.
Step S302, receiving the successful number portability message sent by the number portability server, paying the reimbursement money to the remittance operator according to the reimbursement amount, so that the number portability server can address the terminal according to the communication number of the terminal in the terminal addressing request under the condition that the number portability server receives the terminal addressing request of the third-party operator.
The number portability successful message is a message sent by the number portability server after the number portability server receives a number portability approval message sent by a transfer-out operator, and the number portability approval message is a message generated and sent to the number portability server under the condition that the transfer-out operator agrees to the compensation amount.
In some embodiments, the number portability server forwards the first number portability request sent by the transfer-in operator to the transfer-out operator. And after receiving the first number portability request sent by the number portability server, the transfer-out operator acquires the compensation amount proposed by the transfer-in operator for the terminal number portability according to the first number portability request and determines whether to agree with the compensation amount. And under the condition that the transfer-out operator agrees to the compensation amount, the transfer-out operator generates a number portability approval message and sends the number portability approval message to the number portability server. The number portability network switching server receives the number portability network switching approval message sent by the switching-out operator, generates a number portability network switching success message according to the number portability network switching approval message, and sends the number portability network switching success message to the switching-in operator. The transfer-in operator receives the successful message of number portability, knows the amount of compensation agreed by the transfer-out operator, and the terminal can be transferred to the transfer-in operator through the number portability.
It should be noted that, after the terminal portability, when the third-party operator addresses the terminal, the third-party operator sends a terminal addressing request to the portability server, and carries the communication number of the terminal in the terminal addressing request. After the number portability network server receives the terminal addressing request, the number portability network server determines the transfer-in operator of the terminal according to the communication number of the terminal and addresses the terminal through the transfer-in operator.
According to the terminal addressing method provided by the embodiment, the transfer-in operator sends a first number portability request to the preset number portability network server, the number portability network server sends a number portability success message to the transfer-in operator after receiving the number portability network approval message sent by the transfer-out operator, and when a third-party operator has a requirement for addressing the terminal, the number portability network server determines the transfer-in operator of the terminal, and then the terminal is addressed, so that the success rate of addressing the terminal is improved, and the situation that a number portability user misses receiving information is avoided.
Fig. 4 is a flowchart of a terminal addressing method provided in the fourth embodiment of the present application, where the method is applicable to an operator server. As shown in fig. 4, the method includes the steps of:
step S401, receiving a third number portability request sent by the terminal, and determining the compensation amount for the transfer-out operator.
And the third number portability request comprises the communication number of the terminal.
In some embodiments, the transfer-in operator receives a third number portability request sent by the terminal, and verifies the authenticity of the communication number of the terminal through the transfer-out operator. And under the condition that the communication number of the terminal is determined to be a real number, the transfer-in operator acquires account balance information of the terminal and credit information of the terminal, and determines the compensation amount of the transfer-out operator according to the account balance information of the terminal and the credit information of the terminal.
It should be noted that, when verifying the authenticity of the communication number of the terminal, the forwarding operator may perform verification by determining whether the terminal can obtain the preset verification code from the forwarding operator. The transfer-in operator can also directly send a communication number query request to the transfer-in operator so as to obtain a feedback result of the transfer-in operator on the authenticity of the terminal communication number.
It should be noted that the credit information of the terminal may be information obtained by the transfer-in operator from the transfer-out operator (that is, the credit information of the terminal is information obtained by evaluating the terminal by the transfer-out operator), or may be information obtained by evaluating the transfer-in operator according to account balance information of the terminal or other information (that is, the credit information of the terminal is obtained by evaluating by the transfer-in operator).
It can be understood that the terminal cannot carry out number portability under the condition that the terminal has arrearages. The terminal user needs to pay corresponding fee in advance, so that the terminal does not waste time and applies for handling the number portability service.
And step S402, generating a second number portability request according to the compensation amount, and sending the second number portability request to the terminal.
The transfer-in operator sends the second number portability request to the terminal so as to obtain the approval of the terminal for the second number portability request.
In some embodiments, the terminal may indicate its approval of the second number portability request by signing the second number portability request.
And step S403, setting the communication number of the terminal as the network forwarding public key of the terminal.
In some embodiments, the network transfer operator sets the communication number of the terminal as the network transfer public key of the terminal. In these embodiments, the transit operator may not send the transit public key of the terminal to the number portability server, but may inform the number portability server of the setting manner of the transit public key in advance, so that the number portability server may directly use the communication number of the terminal as the transit public key of the terminal.
And step S404, generating a network switching private key of the terminal based on the preset initial secret key, the public parameter and the network switching public key of the terminal.
In some embodiments, the network-forwarding private key of the terminal is generated Based on an Identity-Based Encryption (IBE) manner. For example, a network forwarding public key PK of the terminal is set as a communication number of the terminal, the preset initial key is MasterKey, the preset public parameter is Para, and a network forwarding private key SK of the terminal is F (MasterKey, Para, PK). Wherein f (x) is a preset key generation function.
And S405, sending the network switching private key of the terminal to the terminal through a preset channel.
The preset channel is a communication channel with a higher security level, the network switching private key is sent through the preset channel, leakage of the network switching private key can be avoided, and the security of the network switching private key is improved.
And step S406, sending the network forwarding public key of the terminal to the number portability server.
The transit public key of the terminal can be used for signature verification and decryption. Specifically, for the information signed or encrypted by the network switching private key of the terminal, the number portability server can use the network switching public key of the terminal to perform signature verification or decryption operation.
Step S407, receiving a first number portability request returned by the terminal, where the first number portability request is a request generated after the terminal signs a second number portability request.
In some embodiments, the terminal signs the second number portability request by using the private network portability key, generates a first number portability request, and sends the first number portability request to the network portability operator.
Because the network forwarding private key can be obtained only by the terminal, the first number portability request signed by the network forwarding private key can represent the approval of the first number portability request by the terminal.
Step S408, a first number portability request is sent to a preset number portability server.
