The number portability and network switching service is also called number portability and number switching without changing, namely, a user of one operator can become a user of another operator after handling the number portability and network switching service without changing the terminal number of the user, and can enjoy various services provided by the other operator.
However, many users currently transact the number portability service, and find that the service provided by the ported-in target operator is not as expected. When the user wants to transfer the terminal number back to the initial operator, the user needs to transact the number portability service again, which brings inconvenience to the user and results in poor service experience of the user.
In order to solve the above problems, the present invention provides a number portability network switching method based on a block chain network, so that a user can perform a pre-network switching operation, a pre-switched operator system of the user can provide temporary operator service experience for the user, and the user can determine whether to switch the number portability to the pre-switched operator system after experiencing the service provided by the pre-switched operator system, thereby avoiding inconvenience caused by the fact that the user finds that the service provided by the switched operator system does not reach the expectation and wants to switch back to the initial operator system after handling the number portability network switching service.
The invention provides a number portability method based on a block chain network, which is applied to a pre-transfer operator system. The method can be implemented in an intelligent contract in a blockchain network comprising a plurality of operator systems and user terminals. As shown in fig. 1, the method comprises the steps of:
step S101, responding to a first network connection request of a user terminal, and acquiring a temporary number portability corresponding to the user terminal, which is broadcasted in advance by an initial operator system, from a block chain network to which the user terminal belongs to transfer out a transaction.
The temporary number portability transfer-out transaction is a transaction which is signed by a user terminal and an initial operator system in advance, and comprises a user identifier corresponding to the user terminal and a temporary transfer-out period, wherein the temporary transfer-out period comprises a time period from the temporary transfer-out starting time to the temporary transfer-out ending time. The initial operator system is the operator system that the user terminal is currently pre-roll-out.
In one embodiment, when a user wants to roll out from an initial carrier system, a temporary roll-out transaction is generated by the user terminal. The temporary number portability transfer-out transaction comprises a user identifier corresponding to the user terminal and a temporary transfer-out period.
As an example, the subscriber identity of the subscriber terminal may be a mobile subscriber number (mobile subscriber international ISDN/PSTN number, msisdn for short), such as a mobile phone number. The data format of the temporary number portability transaction may be: t isout{[msisdn→WildCard，duration d]Therein, [ msisdn → Wildcard, duration d]Is the temporary take-over transaction ToutMsisdn is the user identification; WildCard indicates that the attribution state of the user identifier is a WildCard state; msisdn → WildCard indicates that the state of the user identification is set to WildCard; duration is a preset intelligent contract function; d is a temporary roll-out period, e.g., 1/2020-1/31/2020; duration d represents that the number portability time limit of the user identifier is set as d; [ msisdn → Wildcard, duration d]Indicating that the home state of the user corresponding to msisdn is set to the wildcard state, and the corresponding temporary roll-out deadline is set to d. In the wildcard state, the user identifier corresponding to the user terminal does not belong to any operator within the temporary roll-out period d.
In one embodiment, after the user terminal generates the temporary serial number transfer-out transaction, the user terminal signs the temporary serial number transfer-out transaction and sends the temporary serial number transfer-out transaction signed by the user terminal to the initial operator system, and the initial operator system signs the temporary serial number transfer-out transaction signed by the user terminal and signed by the initial operator system and broadcasts the temporary serial number transfer-out transaction signed by the user terminal and the initial operator system to the blockchain network.
In one embodiment, the first network connection request includes a temporary serial number transfer-out transaction identifier, and the pre-entry operator system obtains a temporary serial number transfer-out transaction corresponding to a user terminal that is broadcast in advance by an initial operator system from a local blockchain network, including: and the pre-transfer operator system obtains the temporary serial number portability transaction corresponding to the temporary serial number portability transaction identifier from the block chain network according to the temporary serial number portability transaction identifier.
And step S102, generating a temporary number portability transaction based on the temporary number portability transfer-out transaction and signing the temporary number portability transfer-in transaction.
Wherein the temporary number portability transaction comprises temporary number portability fee information.
In one embodiment, to improve security, the step of generating a temporary number portability transaction based on the temporary number portability transaction by the pre-roll operator system comprises: sending a network authentication request aiming at the user terminal to the initial operator system according to the signature of the initial operator system in the temporary number portability transfer transaction, for example, extracting an operator system identifier from the signature of the initial operator system, sending the network authentication request aiming at the user terminal to the initial operator system corresponding to the operator system identifier so that the initial operator system authenticates the user terminal based on the network authentication request, and returning an authentication success message or an authentication failure message; under the condition of the received authentication success message, responding to the authentication success message which is fed back by the initial operator system and aims at the user terminal, and generating a temporary number portability to be transferred into the transaction; and under the condition of the received authentication failure message, refusing to provide the temporary network access service for the user terminal in response to the authentication failure message which is fed back by the initial operator system and aims at the user terminal.
In one embodiment, the temporary number portability transaction is a transaction which is signed by the user terminal and signed by the initial operator system in advance, and comprises a user identifier corresponding to the user terminal and a temporary destage deadline. In order to save system resources and avoid an illegal terminal operating by using an expired transaction, before the pre-transfer operator transfers the signature of the initial operator system in the transaction according to the temporary number portability and sends a network authentication request aiming at the user terminal to the initial operator system, the method further comprises the following steps: judging whether the current system date is within a temporary transfer-out period or not, wherein the current system date is the self system date currently identified by a pre-transfer operator system; under the condition that the current system date is judged not to be within the temporary transfer-out period, the pre-transfer operator system refuses to provide temporary network access service for the user terminal; and under the condition that the current system date is judged to be within the temporary transfer-out period, executing the step of sending a network authentication request aiming at the user terminal to the initial operator system according to the signature of the initial operator system in the temporary number portability transaction.
In one embodiment, the temporary number portability transactions generated by the pre-ported operator system include at least one temporary number portability tariff transaction, each temporary number portability tariff transaction including a corresponding temporary number portability tariff information.

In one embodiment, the step of signing the temporary piggyback transaction by the pre-roll-in carrier system comprises: and signing each temporary number portability transaction contained in the temporary number portability transaction by using a private key of the pre-ported operator system.
And step S103, transferring the temporary mobile number signed by the mobile terminal into a transaction and sending the transaction to the user terminal.
It should be noted that, because the two parties involved in the temporary serial number portability transaction are the pre-ported operator system and the user terminal, the temporary serial number portability transaction signed only by the pre-ported operator system is still an unsuccessful transaction in the blockchain network, and the temporary serial number portability transaction does not have a constraint effect on the two parties of the transaction at present. The pre-transfer operator system sends the temporary portability signed by the pre-transfer operator system to the user terminal through step S103, so that the user terminal can sign the temporary portability signed by the pre-transfer operator system to the transaction additional terminal, and after the signature is added, the temporary portability with the signature pre-transfer operator system and the user terminal is transferred to the transaction broadcast to the block chain network, so that the transaction of the temporary portability is established. If the user terminal broadcasts the temporary number portability transaction without adding a signature to the temporary number portability transaction, or if the temporary number portability transaction of which the blockchain network still does not receive the signature of the additional terminal broadcasted by the user terminal within a certain time, the temporary number portability transaction is invalid.
In one embodiment, after the user terminal receives the temporary token-plus-transaction signed by the pre-roll-in operator system, each temporary token-plus-transaction signed by the pre-roll-in operator system included in the temporary token-plus-transaction signed by the pre-roll-in operator system is subjected to a tariff transaction additional signature, and the temporary token-plus-transaction with the signatures of the pre-roll-in operator system and the user terminal is broadcasted into the blockchain network.

In one embodiment, after acquiring the temporary mobile number transfer transaction broadcasted by the user terminal in the affiliated blockchain network, the pre-transfer operator system determines whether the temporary mobile number transfer transaction is established, that is, identifies whether the temporary mobile number transfer transaction broadcasted by the user terminal has a self-signature and a signature of the user terminal. And under the condition that the temporary portability number broadcasted by the user terminal is identified to be transferred into the transaction without the self signature or the signature of the user terminal, refusing to provide the temporary network access service for the user terminal.
And step S105, providing the temporary network access service for the user terminal under the condition that the temporary portability of the user terminal broadcast is identified that the transaction has the self signature and the signature of the user terminal.
The pre-transfer operator system identifies that the temporary number portability transaction broadcasted by the user terminal has self signature and the signature of the user terminal, and shows that the temporary number portability transaction is established currently, and the pre-transfer operator system and the user terminal have constraint effectiveness. The pre-transfer-in operator system provides temporary network access service for the user terminal based on the temporary number portability transaction so that the user terminal can experience the temporary service provided by the pre-transfer-in operator system.
In an embodiment, after providing the network access service for the user terminal, in a case where the user terminal needs to re-access the network, for example, in a case where the user terminal is restarted after being powered off, or an area covered by a network signal is performed from an area not covered by the network signal, as shown in fig. 2, the method for number portability based on a blockchain network further includes:
step S201, receiving a second network connection request sent by the user terminal, where the second network connection request includes a temporary number portability transaction identifier and a temporary number portability transaction identifier.
In the case that the temporary number portability transaction includes at least one temporary number portability transaction, the temporary number portability transaction identifier may include temporary number portability transaction identifiers corresponding to the temporary number portability transaction.
Step S202, according to the temporary number portability transferring transaction identification, the temporary number portability transferring transaction corresponding to the temporary number portability transferring transaction identification is obtained from the block chain network.
Step S203, determine whether the current system date is within the temporary transfer-out deadline in the temporary number portability transfer-out transaction.
Wherein the current system date is the current self-system date identified by the pre-transfer operator system.
In one embodiment, the pre-roll-in operator system refuses to provide the network access service for the user terminal in case that the current system date is judged not to be within the temporary roll-out period.
And step S204, under the condition that the current system date is judged to be within the temporary transfer-out period, acquiring a temporary number portability corresponding to the temporary number portability transfer-in transaction identifier from the block chain network according to the temporary number portability transfer-in transaction identifier.
In one embodiment, after the pre-roll-in operator system acquires the temporary number portability transaction corresponding to the temporary number portability transaction identifier from the blockchain network, the system identifies whether the temporary number portability transaction has the self signature and the signature of the user terminal. And under the condition that the temporary number portability transaction is identified to have no self signature or the signature of the user terminal, refusing to provide the network access service for the user terminal.
And step S205, under the condition that the temporary portability transaction is identified to have the self signature and the signature of the user terminal, providing network access service for the user terminal.
In some implementation scenarios, under the condition that a user corresponding to a user terminal is satisfied with temporary services provided by a pre-transfer operator system, the user can officially handle a number portability service to become an official user of the pre-transfer operator system; under the condition that a user corresponding to the user terminal is not satisfied with the temporary service provided by the pre-transfer operator system, the user terminal can continue to achieve the temporary number portability transfer transaction with other pre-transfer operator systems within the temporary transfer-out period contained in the temporary number portability transfer transaction, or regenerate the temporary number portability transfer transaction and achieve the temporary number portability transfer transaction with other pre-transfer operator systems, so as to experience the temporary service provided by other pre-transfer operator systems until the satisfied temporary service provided by the pre-transfer operator system is met. If the user terminal is not satisfied with all temporary services provided by the pre-transfer operator system, the user terminal can continue to belong to the initial operator corresponding to the initial operator system without handling the number portability service.
The embodiment of the invention provides a number portability method based on a block chain network, which comprises the steps of firstly, responding to a first network connection request of a user terminal, obtaining a temporary number portability transaction corresponding to the user terminal, which is broadcasted in advance by an initial operator system, from a belonging block chain network, wherein the temporary number portability transaction is a transaction which is signed by the user terminal and signed by the initial operator system in advance and comprises a user identifier corresponding to the user terminal and a temporary portability deadline; secondly, generating a temporary number portability transfer transaction and signing the temporary number portability transfer transaction based on the temporary number portability transfer transaction, wherein the temporary number portability transfer transaction comprises temporary number portability transfer tariff information; then, the temporary portable number signed by the user is transferred into a transaction and sent to the user terminal; and finally, acquiring the temporary number portability of the user terminal broadcast in the affiliated block chain network to be transferred into the transaction, and providing temporary network access service for the user terminal under the condition that the temporary number portability of the user terminal broadcast in the transaction is recognized to have self signature and the signature of the user terminal, namely realizing the pre-network transfer service provided for the user, so that the user can experience the service provided by the pre-transferred operator system firstly and then decide whether to handle the number portability service or not, the convenience of the user can be improved, and the user experience is improved.
The embodiment of the invention provides a number portability method based on a block chain network, which is applied to a user terminal. The method can be implemented in a manner of intelligent contracts in a blockchain network. As shown in fig. 3, the method comprises the steps of:
step S301, sending a first network connection request to the pre-roll-in operator system, so that the pre-roll-in operator system obtains a temporary take-off transaction pre-broadcast by the initial operator system from the affiliated blockchain network in response to the first network connection request, and then generates a temporary take-off transaction based on the temporary take-off transaction and signs the temporary take-off transaction.
The temporary number portability transferring transaction is a transaction which is signed by the user and an initial operator system in advance, and comprises a user identifier corresponding to the user terminal and a temporary transferring deadline, and the temporary number portability transferring transaction comprises temporary number portability information.
In one embodiment, before the user terminal sends the first network connection request to the pre-transfer operator system, the method includes: generating a temporary take-out transaction. As an example, the data format of the temporary number portability transaction may be: t isout{[msisdn→WildCard，duration d]Therein, [ msisdn → Wildcard, duration d]Is the temporary take-over transaction ToutMsisdn is the user identification; WildCard indicates that the attribution state of the user identifier is a WildCard state; msisdn → Wildcard indicates that the user is identifiedSetting the state to be a wildcard state; duration is a preset intelligent contract function; d is a temporary roll-out period, e.g., 1/2020-1/31/2020; duration d represents that the number portability time limit of the user identifier is set as d; [ msisdn → Wildcard, duration d]Indicating that the home state of the user corresponding to msisdn is set to the wildcard state, and the corresponding temporary roll-out deadline is set to d. In the wildcard state, the user identifier corresponding to the user terminal does not belong to any operator within the temporary roll-out period d.
Because the user identifier corresponding to the user terminal does not belong to any operator, the user terminal cannot automatically select a network and log in. The user terminal may select the pre-entry operator system automatically by the block link point or manually by the user through a pre-stored list of available networks (or from a pre-designated operator). In addition, the user terminal may connect to the network through the WIFI hotspot at this time to complete operations that need to perform information transmission, such as sending the first network connection request to the pre-transfer operator system in step S301.
The user terminal also signs the temporary number portability transaction, sends the self-signed temporary number portability transaction to the initial operator system so that the initial operator system signs the temporary number portability transaction, and broadcasts the temporary number portability transaction with the signature of the user terminal and the signature of the initial operator system to the block chain network. It should be noted that, because the two transaction parties involved in the temporary serial number portability transaction are the user terminal and the initial operator system, the temporary serial number portability transaction signed only by the user terminal is still an unsuccessful transaction in the blockchain network, and the temporary serial number portability transaction does not have a constraint effect on the two transaction parties at present. The user terminal sends the temporary number portability roll-out transaction signed by the user terminal to the initial operator system through the above, so that the initial operator system signs the temporary number portability roll-out transaction, and broadcasts the temporary number portability roll-out transaction with the signature of the user terminal and the signature of the initial operator system to the block chain network, so that the temporary number portability roll-out transaction is established.
Step S302, receiving the temporary number portability transaction signed by the pre-transfer operator system sent by the pre-transfer operator system.
And step S303, signing the temporary number-portability transaction signed by the pre-transfer operator system.
In one embodiment, the temporary number portability transaction comprises at least one temporary number portability transaction signed by a pre-ported operator system. The step that the user terminal signs the temporary number portability transaction signed by the pre-ported operator system comprises the following steps: and each temporary number portability signed by the pre-transfer operator system included in the temporary number portability transaction signed by the pre-transfer operator system is transferred to a charge transaction additional signature, and the temporary number portability with the signature of the pre-transfer operator system and the user terminal is broadcasted to the block chain network.
Step S304, the temporary number portability transaction with the self signature is broadcasted to the blockchain network, so that the pre-portability operator system provides the temporary network access service under the condition that the temporary number portability transaction is identified to have the signature of the user terminal and the signature of the pre-portability operator system.
When the user terminal broadcasts the temporary portability number signed by the user terminal to the transaction to the blockchain network, the temporary portability number is transferred to the transaction, and the temporary portability number is transferred to the transaction and has constraint effect on pre-transferring to an operator system and the user terminal.
In an embodiment, in a case that the user terminal needs to re-access the network corresponding to the pre-ported-to operator system, for example, in a case that the user terminal is restarted, rebooted after being powered off, or an area with network signal coverage is performed from an area without network signal coverage, the method further includes:
and sending a second network connection request to the pre-roll-in operator system, so that after the pre-roll-in operator system receives the second network connection request, obtaining a temporary number portability transaction corresponding to a temporary number portability transaction identifier contained in the second network connection request from the blockchain network, obtaining the temporary number portability transaction corresponding to the temporary number portability transaction identifier contained in the second network connection request from the blockchain network under the condition that the current system date is judged to be within the temporary portability deadline, and providing network access service under the condition that the temporary number portability transaction has a self signature and a signature of the user terminal.
In some implementation scenarios, when a user corresponding to a user terminal is satisfied with a temporary service provided by a pre-transfer operator system, the user terminal can officially handle a number portability service to become an official user of the pre-transfer operator system; under the condition that a user corresponding to the user terminal is not satisfied with the temporary service provided by the pre-transfer operator system, the user terminal can continue to achieve the temporary number portability transfer transaction with other pre-transfer operator systems within the temporary transfer-out period contained in the temporary number portability transfer transaction, or regenerate the temporary number portability transfer transaction and achieve the temporary number portability transfer transaction with other pre-transfer operator systems, so as to experience the temporary service provided by other pre-transfer operator systems until the satisfied temporary service provided by the pre-transfer operator system is met. If the user terminal is not satisfied with all temporary services provided by the pre-transfer operator system, the user terminal can continue to belong to the initial operator corresponding to the initial operator system without handling the number portability service.
In some implementation scenarios, in a case that a temporary roll-out period included in the temporary number portability roll-out transaction expires and the user terminal does not handle the number portability network service, or the user terminal wants to continue to belong to an initial operator corresponding to the initial operator system, the user terminal detects that its own card information is not changed (for example, SIM card information is not changed), and then the user terminal automatically sends a third network connection request to the initial operator system, so that the initial operator system responds to the third network connection request and provides a network access service based on pre-stored user information corresponding to the user terminal, where the third network connection request does not include the temporary number portability transaction identifier and the temporary number portability transaction identifier.
The invention provides a number portability method based on a block chain network, which comprises the steps of firstly, sending a first network connection request to a pre-ported operator system so that the pre-ported operator system can respond to the first network connection request, obtaining a temporary number portability transfer-out transaction broadcasted in advance by an initial operator system from a affiliated block chain network, generating the temporary number portability transfer-in transaction based on the temporary number portability transfer-out transaction and signing the temporary number portability transfer-in transaction, wherein the temporary number portability transfer-in transaction comprises temporary number portability transfer-in charge information; the temporary number portability transfer-out transaction is a transaction which is signed by the temporary number portability transfer-out transaction and an initial operator system in advance, and comprises a user identifier corresponding to the user terminal and a temporary transfer-out deadline; secondly, receiving a temporary number portability switching transaction which is sent by the pre-switching operator system and signed by the pre-switching operator system; then, the temporary number-carrying transfer-in transaction signed by the pre-transfer-in operator system is signed; and finally, the temporary number portability transaction which is signed by the pre-portability operator system is broadcasted to the blockchain network, so that the pre-portability operator system provides temporary network access service under the condition that the temporary number portability transaction is identified to have the signature of the user terminal and the signature of the pre-portability operator system, namely the pre-portability operator system realizes the pre-portability service provided for the user, the user can experience the service provided by the pre-portability operator system firstly and then decide whether to handle the number portability service or not, the convenience of the user can be improved, and the user experience is improved.
