In the embodiment of the present application, when the terminal registers, the terminal transmits the first registration request to the second server of any one of the plurality of second servers. The embodiment of the present application does not particularly limit the second server of any one of them. The second server of any one of them may be a server corresponding to a base station servicing the area where the terminal is located.

Notification signaling for the terminal is transmitted to the terminal. The terminal further receives the notification signaling and sends a first registration request to any one of the second servers based on the terminal's public key.

In one possible embodiment, each second server further monitors in real time whether there are any newly joining terminals in the area served by the base station corresponding to the second server. When it is monitored that a newly participating terminal exists in the area served by the base station, a notification signaling is transmitted to the newly participating terminal.

Triggered based on the signaling of the second server, it can be registered in a timely manner, and the timeliness and reliability of terminal registration can be guaranteed.

(1-2), the at least one first server verifies the terminal based on the public key of the terminal, and returns a verification result for showing the success or failure of the verification for the terminal.

In the embodiment of the present application, a plurality of public keys and verification information corresponding to each public key are stored in the at least one first server, and the verification information is used as the IMSI (International) of the terminal. It includes, but is not limited to, Mobile Subscriber Identity Number (International Mobile Subscriber Identification Number) information and communication charge balance information of the terminal.

The at least one first server further acquires verification information corresponding to the public key, that is, verification information of the terminal, based on the public key of the terminal, and the terminal is based on the verification information of the terminal. To verify.

Here, the at least one first server is a terminal of a user for whom the terminal is valid, and the remaining call charge of the terminal is larger than a predetermined threshold, that is, based on the IMSI information of the terminal. If it is verified that the terminal is a legitimate terminal and is qualified to use the communication service, it is considered that the verification for the terminal is successful, and conversely, the terminal is valid based on the IMSI information of the terminal. If it is verified that the terminal is not a user's terminal, or that the remaining call charge of the terminal is equal to or less than the predetermined threshold value, it is assumed that the terminal fails in the verification.

The any one second server further receives the verification result transmitted from the at least one first server, and among the plurality of second servers, the second server other than the present server. The verification result is transmitted.

Here, in the terminal registration process, the public key of the terminal in the target blockchain is the information agreed by the plurality of second servers. In the consensus building process, the plurality of second servers further form a consensus on the public key of the terminal, and when the consensus is reached, record the public key of the terminal in the target blockchain.

Here, when the plurality of second servers form a consensus on the block, the role of the plurality of second servers may be realized by the witness server among the plurality of second servers. , The witness server may be a server elected by a consensus algorithm. In the consensus building process, the roles of the witness server and the plurality of second servers are as follows.

If the verification result indicates successful verification of the terminal, the witness server further packetizes the public key of the terminal to generate a block, and uses the block as a plurality of second servers in the blockchain network. Of these, transmission is performed to a plurality of second servers other than this server. The plurality of second servers further form an agreement on the block, and when the agreement is reached, record the block on the target blockchain.

Here, when the plurality of second servers further agree on the block of the second server exceeding a predetermined number among the plurality of second servers, the block becomes a target blockchain. Record.

The agreement algorithm may be a PBFT (Practical Byzantine Fault Tolerant) algorithm, and the PBFT algorithm may be a malicious server or no response among the plurality of second servers. It is permissible for servers to exist, for example, if there are 3f + 1 second servers in the blockchain network, then there are f unresponsive or malicious servers (f is greater than 1 positive). Integer). The predetermined number may be two-thirds or one-third of the total number of the plurality of second servers, and the embodiments of the present application do not particularly limit this. In the embodiment of the present application, the non-response server refers to a server among a plurality of second servers that does not respond to the verification result for the block.

In order to more clearly explain the terminal registration process, the present embodiment describes the terminal registration process by taking a second server of one of a plurality of second servers as an example, and the second. The server may be any of the plurality of second servers, and the embodiments of the present application do not particularly limit this. FIG. 3 is a flowchart of a terminal registration method, and as shown in FIG. 3, the method includes the following steps 301 to 307.

In step 301, the second server sends a notification signaling to the terminal to instruct the terminal to send the public key of the terminal to the second server.

Here, the second server can trigger the reporting of the public key to the second server of the terminal by signaling. The second server further monitors in real time whether or not there is a newly participating terminal in the area serviced by the base station corresponding to the second server, and the base station services. When it is monitored that there is a newly participating terminal in the existing area, notification signaling can be transmitted to the newly participating terminal.

In step 302, the terminal receives the notification signaling and sends a first registration request to the second server based on the terminal's public key.

Here, the first registration request includes the public key of the terminal.

In step 303, the second server receives the first registration request for the terminal.

The second server acquires the public key of the terminal from the registration request.

In step 304, the second server transfers the public key of the terminal to the at least one first server.

In step 305, the at least one first server verifies the terminal based on the public key of the terminal and returns the verification result.

Here, the verification result is for showing the success or failure of the verification for the terminal. The at least one first server acquires the verification information corresponding to the public key, that is, the verification information of the terminal, based on the public key of the terminal, and verifies the terminal with the verification information of the terminal. be able to. Here, it is verified that the at least one first server is a terminal of a valid user and the remaining call charge of the terminal is larger than a predetermined threshold value based on the IMSI information of the terminal. If so, it is assumed that the verification for the terminal is successful, and conversely, based on the IMSI information of the terminal, the terminal is not a valid user's terminal, or the remaining call charge of the terminal is equal to or less than the predetermined threshold. If it is verified that the terminal has failed the verification. The any one second server receives the verification result transmitted from the at least one first server, and among the plurality of second servers, the verification is performed on a second server other than the main server. Send the result.

In step 306, if the verification result indicates successful verification of the terminal, the second server records the public key of the terminal in the target blockchain.

Here, in the terminal registration process, the public key of the terminal in the target blockchain is the information agreed by the plurality of second servers. In the consensus building process, the plurality of second servers form a consensus on the public key of the terminal, and when the consensus is reached, the public key of the terminal is recorded in the target blockchain.

Here, when the plurality of second servers form a consensus on the block, the process of putting the public key of the terminal into the chain may be realized by the witness server among the plurality of second servers. , The witness server may be a server elected by a consensus algorithm.

In the consensus building process, when the verification result indicates the verification success of the terminal, the witness server packetizes the public key of the terminal to generate a block, and the block is converted into a plurality of orders in the blockchain network. Of the two servers, transmission may be performed to a plurality of second servers other than this server. The plurality of second servers form an agreement on the block, and when the agreement is reached, the block is recorded on the target blockchain.

Here, the plurality of second servers further target the block when an agreement is reached on the block among the second servers exceeding a predetermined number among the plurality of second servers. It may be recorded on the blockchain.

The agreement algorithm may be a PBFT algorithm, and the PBFT algorithm can allow a malicious server or a non-responding server to exist in the plurality of second servers, for example, a blockchain. If there are 3f + 1 second servers in the network, allow f f unresponsive or malicious servers. In the embodiment of the present application, the non-response server refers to a server among a plurality of second servers that does not respond to the verification result for the block.

In step 307, the second server sends a registration success notification to the terminal.

In the terminal registration process, the terminal sends the public key of the terminal to the second server, the second server transfers the public key to the first server, and the first server verifies the terminal. If the verification is successful, the unauthorized terminal is eliminated by recording the public key of the terminal in the target blockchain through the agreement formation process by the plurality of second servers, and the base station corresponding to the second server is released. , Guarantee that the communication service is provided only to the terminal that has been successfully verified, and further improve the reliability of the terminal registration process and the accuracy and security of the subsequent communication connection.

Even if the base station initializes and accesses the network, or even after the base station loses connection due to a link and re-enters the network, the server corresponding to the base station before joining the blockchain network. Must be registered in the core network. Here, in the registration process of the registration target server, the role of the at least one first server is as follows.

(2-1), the first server of any one of the at least one first server further receives the second registration request of the server to be registered, and the registration in the second registration request. The registration target server is verified based on the public key of the target server, and if the verification for the registration target server is successful, the public key of the registration target server is transmitted to the plurality of second servers, and the registration target is registered. Send a registration success notification to the server.

Here, the second registration request requests registration as a second server in the blockchain network. The at least one first server stores the public key of the server qualified to participate in the blockchain network and the base station identifier of the base station corresponding to the server qualified to participate in the blockchain network. ing.

The at least one first server further searches for the public key of the registration target server from the correspondence between the public key stored in the server and the base station identifier based on the public key of the registration target server. However, if the public key of the registration target server is found, it is assumed that the verification for the registration target server is successful.

In one possible embodiment, the at least one first server further bases on the registration target server, based on the correspondence between the public key and the base station identifier, based on the public key of the registration target server. When the station is acquired, the base station corresponding to the registration target server is verified, and the verification is successful, the registration target server is qualified to participate in the blockchain network, and the verification of the registration target server by the server is performed. Determine to be successful.

In one possible embodiment, the at least one first server further provides the plurality of second servers with the public key of the registration target server and the base station identifier of the base station corresponding to the registration target server. And send.

In addition, the at least one first server further transmits the public key of the registration target server to the second server of any one of the plurality of second servers, and the first one of the registration target servers. The second server transmits the public key of the registration target server to a plurality of second servers of the blockchain network.

Here, the base station identifier of the base station may be the ID (identity, identity identifier) information of the base station.

Further, in the process of registering the server as the second server, the roles of the plurality of second servers in the blockchain network are as follows.

(2-2), the plurality of second servers further record the public key of the registration target server in the target blockchain.

In one possible embodiment, the plurality of second servers further record the public key of the registration target server and the base station identifier of the base station corresponding to the registration target server in the target blockchain. , Achieve an agreement on the identity of the server to be registered as the second server.

As a matter of course, in the server registration process, the public key of the registration target server is also the information agreed in the consensus building process by the plurality of second servers. In the consensus building process, the plurality of second servers further form a consensus on the public key of the registration target server, and when the agreement is reached, record the public key of the registration target server in the target blockchain. Here, the consensus building process may be realized based on the witness server among the plurality of second servers, and the role of the plurality of second servers is the same as the consensus building process at the time of terminal registration. It has a similar role.

In order to more clearly explain the server registration process, the present embodiment describes the server registration process by taking one first server as an example, and the first server is a plurality of first servers. Any of the servers may be used, and the embodiments of the present application do not particularly limit this. FIG. 4 is a flowchart of a server registration method, which, as shown in FIG. 4, includes the following steps 401-404.

In step 401, the registration target server transmits a second registration request to the first server based on the public key of the registration target server.

Here, the second registration request includes the public key of the registration target server.

In step 402, the first server receives the second registration request of the registration target server and verifies the registration target server based on the public key of the registration target server in the second registration request.

Based on the public key of the registration target server, the at least one first server searches for the public key of the registration target server from the correspondence between the public key stored in the server and the base station identifier. If the public key of the registration target server is found, it is assumed that the verification for the registration target server is successful.

In one possible embodiment, the at least one first server will further be based on the public key of the server to be registered, and if the public key of the server to be registered is found, the public key and the base station identifier. From the correspondence relationship, the base station corresponding to the registration target server is acquired, the base station corresponding to the registration target server is verified, and if the verification is successful, the registration target server is eligible to participate in the blockchain network. Then, it is assumed that the verification of the registration target server by the server is successful. If the verification of the base station corresponding to the registration target server fails, it is determined that the registration target server is not qualified to participate in the blockchain network, and the verification of the registration target server by the server fails. do.

In step 403, when the verification for the registration target server is successful, the first server transmits the public key of the registration target server to the plurality of second servers, and sends a registration success notification to the registration target server. do.

In one possible embodiment, the at least one first server further provides the plurality of second servers with the public key of the registration target server and the base station identifier of the base station corresponding to the registration target server. And can be sent.

As a matter of course, when the verification of the registration target server by the server fails, the first server does not send the public key of the registration target server to the plurality of second servers, and the registration target does not send the public key of the registration target server. The server also cannot participate in the blockchain network.

In step 404, the plurality of second servers record the public key of the registration target server in the target blockchain.

Here, the plurality of second servers in the blockchain network form an agreement on the public key of the registration target server, and when the agreement is reached, the public key of the registration target server is recorded in the target blockchain. As a matter of course, the plurality of second servers can further record the public key of the registration target server and the base station identifier of the base station corresponding to the registration target server in the target blockchain.

Here, the plurality of second servers can realize a process of putting the public key of the registration target server into the chain by a consensus building process based on the witness server. The process in this step is the same as that in step 306.

In the process of being registered as the second server in the blockchain network, the verification was successful by the verification by the first server and the consensus formation by the plurality of second servers in the blockchain network. The public key of the server is accurately recorded in the target blockchain, the accuracy of server registration is improved, and the consensus formation of a plurality of subsequent second servers for the amount of communication data and the communication billing data is facilitated.

In the embodiment of the present application, when the terminal succeeds in registration, the terminal can receive the communication service provided by the base station. In general, one terminal can detect signals of a plurality of base stations at the same time. The target blockchain records the charge rates of a plurality of base stations, and the terminal starts a consignment contract and informs the second server of the high and low rates of the plurality of base stations. By outsourcing, it is possible to later select the base station with the lowest charge rate and have the terminal provide the communication service. In the process of the terminal initiating the consignment contract, the roles of the terminal and the plurality of second servers are as follows.

(3-1), the terminal further transmits the first consignment contract to the plurality of second servers, and the first consignment contract transmits at least the base station identifiers of the plurality of base stations. include.

The plurality of base stations are base stations to which the terminal can receive signals.

The terminal further monitors the signals of the plurality of receivable base stations in real time, and generates the first consignment contract based on the base station identifiers of the plurality of base stations capable of receiving the signals. The first consignment contract is transmitted to the second server of the above. In addition, the terminal further transmits the first consignment contract to the second server of any one of the plurality of second servers. The embodiment of the present application does not particularly limit the second server of any one of them, and for example, the second server of any one of them is a server corresponding to a base station servicing the area where the terminal is located. It may be there.

In one possible embodiment, the terminal further monitors the signal strengths of the plurality of base stations in real time based on the received signals of the plurality of base stations, and based on the signal strengths of the plurality of base stations. , Delete a base station having a signal strength lower than the target signal strength from a plurality of base stations capable of receiving a signal. The target signal strength is the lowest signal strength that satisfies the communication demand of the terminal, and can be further selected from the base stations having the higher signal strength later to significantly satisfy the communication service demand of the terminal.

In one possible embodiment, the terminal also acquires the service conditions of the terminal and adds the service conditions to the first consignment contract. The first consignment contract may further include service conditions for the terminal, which are intended to indicate the target service quality of the base station required for the terminal.

In one possible embodiment, the terminal further performs a step of transmitting the first consignment contract to the second server only if the terminal satisfies the contract start condition, and the contract start condition is This includes the fact that the terminal has been successfully registered, or that the number of base stations whose signal strength has reached the target signal strength among the candidate base stations of the terminal does not exceed a predetermined threshold value.

Further, the terminal signs the first consignment contract with the terminal's private key, and the signature may be a digital signature.

In the communication process, when the communication service provided by the base station cannot meet the communication demand, for example, when the signal strength of the original base station is weakened due to the position change of the terminal, the terminal is the original. It is necessary to switch to another base station that can meet the communication demand. Further, immediately after the terminal succeeds in registration, the terminal has not yet determined the target base station, and in this case, the terminal selects the target base station based on the charge rate instruction information of the second server. As such, the first consignment contract may be transmitted to the second server.

(3-2), the plurality of second servers further form an agreement on the first consignment contract, and when the agreement is reached, the first consignment contract is recorded in the target blockchain.

Here, the first consignment contract in the target blockchain is a contract agreed by a consensus building process by a plurality of second servers. In the consensus building process, the plurality of second servers further verify the signed first consignment contract based on the public key of the terminal, and if the verification is successful, the first consignment contract. On the target blockchain.

As a matter of course, in the process of consensus building on the first consignment contract, the role of the plurality of second servers may be realized based on the witness server among the plurality of second servers. Correspondingly, the role of the plurality of second servers is the same as the consensus building process at the time of terminal registration.

In order to more clearly explain the process by which the terminal initiates the consignment contract, the present embodiment exemplifies that the terminal transmits the first consignment contract to any one of the second servers. Explains the process of initiating a consignment contract, but the embodiments of the present application do not particularly limit this. FIG. 5 is a flowchart of a method in which the terminal initiates a consignment contract, which method comprises the following steps 501-502, as shown in FIG.

In step 501, the terminal transmits the first consignment contract to any one second server.

Here, the first consignment contract includes at least the base station identifiers of the plurality of base stations. The plurality of base stations are base stations to which the terminal can receive signals. The terminal may monitor the signals of the plurality of receivable base stations in real time and generate the first consignment contract based on the base station identifiers of the plurality of base stations capable of receiving the signals. The terminal signs the first consignment contract with the private key of the terminal, and transmits the signed first consignment contract to the plurality of second servers.

In one possible embodiment, the terminal further monitors the signal strengths of the plurality of base stations in real time based on the received signals of the plurality of base stations, and based on the signal strengths of the plurality of base stations. , It is possible to delete a base station having a signal strength lower than the target signal strength from a plurality of base stations capable of receiving a signal.

In one possible embodiment, the terminal can further acquire the service conditions of the terminal and add the service conditions to the first consignment contract. The service condition is for indicating the target service quality of the base station required for the terminal.

In one possible embodiment, step 501 is performed only if the terminal meets the contract start condition, where the contract start condition is that the terminal has successfully registered or is a candidate for the terminal. In the base station list, the number of base stations satisfying the signal condition that the signal strength is equal to or higher than the target signal strength does not exceed a predetermined threshold value.

When the terminal transmits the first consignment contract to any one of the second servers, the one of the second servers has a plurality of the first consignment contracts in the blockchain network. Broadcast to a second server.

In step 502, the plurality of second servers form a consensus on the first consignment contract, and when the consensus is reached, the first consignment contract is recorded in the target blockchain.

In the consensus building process, the plurality of second servers verify the digitally signed first consignment contract based on the public key of the terminal. If the verification is successful, the first consignment contract is recorded on the target blockchain. Here, the plurality of second servers in the blockchain network can form a consensus on the first consignment contract, and when the consensus is reached, the first consignment contract can be recorded in the target blockchain. .. Not surprisingly, the plurality of second servers can also record the first consignment contract on the target blockchain.

Here, the plurality of second servers can realize the process of putting the first consignment contract into the chain by the consensus building process based on the witness server. The process in this step is the same as that in step 306.

When the terminal can transmit the first consignment contract, the plurality of second servers form a consensus on the first consignment contract, and the first consignment contract for which the agreement has been reached is executed. Can be recorded on the target blockchain. This guarantees the accuracy and reliability of the information on the target blockchain. Further, the recording process of the consignment contract triggers a plurality of second servers to assign a base station to the terminal, and the consignment process is merely an interaction process between the terminal and the second server. It does not increase the signaling overhead of the operator's first server.

In the embodiment of the present application, when the second server joins the blockchain network, the second server starts a consignment contract and sets the charge rate of the base station corresponding to the second server to the target blockchain. It can be recorded publicly and transparently. In the process of the second server initiating the consignment contract, the roles of the plurality of second servers are as follows.

(4-1), each second server of the plurality of second servers is further based on the rate of at least one base station corresponding to each second server, the blockchain network. The second consignment contract is transmitted to a plurality of second servers other than this server.

Here, the second consignment contract includes the rate of at least one base station corresponding to each of the second servers. Further, each of the second servers further signs the second consignment contract with the private key of each of the second servers, and a plurality of second servers other than the present server in the blockchain network. Sends a signed second consignment contract to.

In one possible embodiment, the second consignment contract may further include the quality of service of the base station, where each second server further includes the quality of service of at least one base station corresponding to each server. And add the quality of service of the at least one base station to the second consignment contract.

In one possible embodiment, each of the second servers further monitors the service quality of the base station corresponding to each of the second servers in real time and services of the base station corresponding to each of the second servers. If you monitor a change in quality, adjust the rate of the base station based on the target adjustment policy and the current service quality of the base station corresponding to each second server, and adjust the rate. Based on the above, the third consignment contract is transmitted to a plurality of second servers other than the present server in the blockchain network. Here, the third consignment contract includes an adjusted rate.

Here, the target adjustment policy is that when the service quality of the base station is too low, the second server corresponding to the base station increases the charge rate of the base station, and the service quality of the base station is too high. A second server corresponding to the base station may reduce the rate of the base station.

In one possible embodiment, the channel resource utilization of the base station can represent the quality of service of the base station, the higher the channel utilization, the busier the base station, the lower the quality of service, and the channel. The lower the utilization rate, the more vacant the base station is and the higher the quality of service. The target adjustment policy is that if the base station's channel resource utilization is too high, the second server increases the base station's rate, and if the base station's channel resource utilization is too low, the second server. The server may reduce the rate of the base station. Here, the target adjustment policy can be specifically embodied as a correspondence relationship between a plurality of levels of the channel resource utilization rate and a plurality of charge rates of the base station, and channel resource utilization depending on the level. The rates are different, and each level corresponds to one rate. The second server adjusts according to the correspondence between the level and the charge rate, and the second server further adjusts according to the level of the current channel resource utilization of the base station. The current charge rate of the base station is acquired from the correspondence between the charge rate and the charge rate.

The second server further periodically acquires the current charge rate of the base station, and whether or not the current charge rate of the base station and the charge rate of the base station in the previous cycle are the same. If they are not the same, a third consignment contract is transmitted to a plurality of second servers other than the present server in the blockchain network based on the current rate.

By recording the charge rate of the base station in the target blockchain by the second server, the charge rate cannot be tampered with, the transparency and reliability of the information are improved, and the load status of the base station is used. Therefore, by adjusting the charge rate of the base station in real time, the load on each base station does not become too large, and the communication service quality and communication service efficiency of the base station are improved. At the same time, the load between the plurality of base stations is balanced, and the service stress of the base station that has become a hot spot is significantly alleviated.

(4-2), the plurality of second servers further form an agreement on the second consignment contract, and when the agreement is reached, the second consignment contract is recorded in the target blockchain.

The plurality of second servers further verify the second consignment contract based on the public key of the server that is the source of the second consignment contract, and if the verification is successful, the second consignment contract. Is recorded on the target blockchain. In one possible embodiment, the plurality of second servers further form a consensus on the third consignment contract, and when the consensus is reached, record the third consignment contract in the target blockchain.

The blockchain network may be provided with a witness server for packetizing a second consensus contract to generate a block and transmitting the block to a plurality of second servers. The plurality of second servers further form an agreement on the block of the witness server, and when the agreement is reached, the block is put into the target blockchain. Correspondingly, when the second server transmits a second consignment contract, the role of each second server is to further witness the second consignment contract within the target blockchain network. Further includes sending to the server.

As a matter of course, in the process of consensus building on the second consignment contract and / or the third consignment contract, the roles of the plurality of second servers and the witness server are the same as the consensus building process at the time of terminal registration. It has a similar role.

Here, the witness server may be one or more servers selected by a plurality of second servers in the blockchain network based on an agreement mechanism. The witness server executes the block packetization process, the plurality of second servers verifies the block, omits the process of packetizing any of the plurality of second servers, and puts the consignment contract into the chain. Increase speed and improve blockchain network processing efficiency.

In order to more clearly explain the process by which the second server initiates the consignment contract, in the present embodiment, any one second server initiates the consignment contract based on the corresponding one base station. This will be described as an example of the process by which the second server initiates the consignment contract, but the embodiment of the present application is not particularly limited to this. FIG. 6 is a flowchart of a method in which the second server initiates a consignment contract, which method includes the following steps 601 to 605, as shown in FIG.

In step 601 the second server is entrusted to a plurality of second servers other than the present server in the blockchain network based on the charge rate of the base station corresponding to the second server. Send the contract.

Here, each of the second servers further signs the second consignment contract with the private key of each of the second servers, and a plurality of second servers other than the present server in the blockchain network. Send the signed second consignment contract to the server.

In step 602, the plurality of second servers form a consensus on the second consignment contract, and when the consensus is reached, the second consignment contract is recorded in the target blockchain.

The plurality of second servers can further verify the second consignment contract based on the public key of the server that is the source of the second consignment contract. In addition, each of the second servers can further transmit the second consignment contract to the witness server in the target blockchain network. The witness server packetizes the second consignment contract to generate a block, transmits the block to a plurality of second servers, and correspondingly, the plurality of second servers further obtain a block. An agreement is formed on the block of the witness server, and when the agreement is reached, the block can be put into the target blockchain. In this step, the process of putting the second consignment contract into the chain is realized by the consensus building process. This is the same process as step 306.

In step 603, the second server monitors the quality of service of the base station in real time, and if it monitors that the quality of service of the base station has changed, it is based on the target adjustment policy and the quality of service of the base station. To adjust the charge rate of the base station.

In an embodiment of the present application, after the second server records the base station charge rate on the target blockchain, each second server further dynamically adjusts the base station charge rate. The service quality of base stations can be guaranteed and the load between multiple base stations can be balanced. Here, the target adjustment policy is that if the service quality of the base station is too low, the second server increases the charge rate of the base station, and if the service quality of the base station is too high, the second server. The server may reduce the rate of charge for the base station.

In one possible embodiment, where the channel resource utilization of a base station represents the quality of service of the base station, the target coordination policy corresponds to the base station if the channel resource utilization of the base station is too high. If the second server increases the charge rate of the base station and the channel resource utilization rate of the base station is too low, the second server corresponding to the base station decreases the charge rate of the base station. You may. Here, the target adjustment policy may be specifically embodied as a correspondence relationship between a plurality of levels of channel resource utilization and a plurality of charge rates of the base station. In one possible embodiment, the second server determines the current rate of the base station from the correspondence between the level and the rate, depending on the level of the base station's current channel resource utilization. Can be obtained.

In step 604, the second server transmits a third consignment contract to a plurality of second servers other than the present server in the blockchain network based on the adjusted rate.

The second server periodically acquires the current charge rate of the base station, and determines whether or not the current charge rate of the base station and the charge rate of the base station in the previous cycle are the same. If it is determined and not the same, the third consignment contract can be transmitted to a plurality of second servers other than the present server in the blockchain network based on the current rate.

In step 605, the plurality of second servers form a consensus on the third consignment contract, and when the agreement is reached, the third consignment contract is recorded in the target blockchain.

This step is the same process as step 602.

By recording the base station charge rate in the target blockchain, the second server makes the charge rate of each base station public and transparent, and is monitored by a plurality of second servers without permission. Make it immutable and make the data source of the later communication billing process more reliable. Further, the second server appropriately adjusts the charge rate of the base station based on the change status of the service quality of each base station, balances the load between the base stations, and provides the base station. It is possible to guarantee the service quality of the communication service to be performed and improve the service efficiency of the communication service of the base station.

The charge rates of a plurality of base stations are acquired, and the charge rate instruction information is returned to the terminal.

Here, the charge rate instruction information is for indicating the level of the charge rate of the plurality of base stations. The charge rate instruction information is a charge rate of a plurality of base stations sorted according to the level of the charge rate, or a charge rate level indicating a high or low status of the charge rate of the plurality of base stations. good. The embodiment of the present application does not particularly limit the charge rate instruction information.

The plurality of second servers further acquire the service qualities of the plurality of base stations, and are included in the first consignment contract based on the service qualities of the plurality of base stations and the service conditions of the terminals. The base stations whose service quality does not meet the service conditions are deleted from the plurality of base stations. Here, the second server further acquires the service quality of the plurality of base stations from the target blockchain, and the service quality of the plurality of base stations is determined based on the service conditions in the first consignment contract. It is determined whether or not the service condition is satisfied.

In one possible embodiment, the plurality of second servers further transmit a charge rate contract to the terminal based on the charge rates of the plurality of base stations, and when an agreement is reached on the charge rate contract, Record the rate contract on the target blockchain. The plurality of second servers further transmit the rate contract to at least one first server. Here, the charge rate contract may include the charge rates of a plurality of base stations after sorting. The sort order of the plurality of base stations can be sorted in descending order according to the level of the charge rate. The plurality of second servers also add the quality of service of the plurality of base stations to the rate contract.

In one possible embodiment, in the process of communication between the base station and the terminal, the charge rate of the base station may change dynamically, that is, a third consignment contract is added to the target blockchain. In the case, the second server further determines a terminal that has established a communication connection with the base station in the third consignment contract based on the third consignment contract, and a terminal that has established a communication connection with the base station. Send the updated rate rate instruction information to.

Here, the plurality of second servers further acquire the first consignment contract of at least one terminal that has established a communication connection with the base station, and the plurality of base stations in the first consignment contract of each terminal. Based on the base station identifier of the above and the base station charge rate in the third consignment contract, the charge rate instruction information of a plurality of base stations in the first consignment contract is redetermined. As a matter of course, the third consignment contract may include the quality of service of the base station, and the plurality of second servers may further include the quality of service of the base station in the third consignment contract. Based on the service conditions in the first consignment contract, the base stations whose service quality does not satisfy the service conditions are deleted from the plurality of base stations included in the first consignment contract.

In the process of recording the rate contract in the target blockchain, the role of the plurality of second servers may be realized by the witness server among the plurality of servers, and the witness server is an agreement algorithm. It may be a witness server selected by. When the witness server receives the first consignment contract of the terminal, the witness server further acquires the charge rates of the plurality of base stations based on the base station identifiers of the plurality of base stations in the first consignment contract. , The charge rate instruction information is returned to the terminal.

The witness server further transmits a charge rate contract to the terminal based on the high and low charge rates of the plurality of base stations, and charges the charges to a server other than the present server among the plurality of second servers. The rate contract is transmitted, and in response to this, the plurality of second servers further form an agreement on the rate contract, and when the agreement is reached, the rate contract is recorded in the target blockchain. Here, the plurality of second servers further target the block when an agreement is reached on the block among the second servers exceeding a predetermined number among the plurality of second servers.

The agreement algorithm may be a PBFT algorithm, and the PBFT algorithm can allow a malicious server or a non-responding server to exist in the plurality of second servers, for example, a blockchain. If there are 3f + 1 second servers in the network, allow f f unresponsive or malicious servers. In the embodiment of the present application, the non-response server refers to a server among a plurality of second servers that does not respond to the verification result for the rate contract.

It should be noted that the plurality of second servers record the charge rate contract in the target blockchain, and later charge the communication process of the terminal based on the charge rate contract for later communication. Billing accuracy is guaranteed. In addition, the plurality of second servers further update the charge rate instruction information for the terminal in real time based on the dynamically updated base station charge rate, so that the charge rate instruction information is accurate. Sexuality and aging can be further guaranteed. Further, by performing an interaction between the second server and the terminal, a process of allocating the base station having the lowest charge rate to the terminal is realized, and the participation of the first server becomes unnecessary in the process, and the core network Reduce signaling overhead.

In addition, by realizing the roles of the plurality of second servers by the witness server selected by the agreement algorithm, damage to the blockchain network of the malicious server or the invalid server is effectively eliminated, and the blockchain network. The influence on the communication system can be reduced and the reliability of the communication system can be improved.

Here, the terminal further selects the target base station having the lowest charge rate from the plurality of base stations according to the level of the charge rate of the plurality of base stations indicated by the charge rate instruction information.

In addition, based on the charge rate instruction information, the terminal selects the target base station having the lowest charge rate and establishes a communication connection, and the communication cost of the terminal is significantly reduced. Further, on the premise that the communication cost of the terminal is reduced by further selecting the base stations that satisfy the service condition for the terminal based on the service quality of the plurality of second servers, the communication demand of the terminal is met. I am most satisfied.

In order to more clearly explain the process in which the second server assigns a base station to a terminal, the present embodiment takes any one of the second servers as an example, and the second server assigns a base station to the terminal. The process of allocation will be described. FIG. 7 is a flowchart of a method in which the second server assigns a base station to a terminal, and as shown in FIG. 7, the method includes the following steps 701 to 702.

In step 701, when the first consignment contract of the terminal is received, the second server charges the plurality of base stations based on the base station identifiers of the plurality of base stations in the first consignment contract. The rate is acquired, and the charge rate instruction information is returned to the terminal.

In this step, the second server acquires a plurality of second consignment contracts from the target blockchain based on the base station identifiers of the plurality of base stations in the first consignment contract, and the plurality of second consignment contracts. Obtain the charge rates of the plurality of base stations from the consignment contract of.

Base stations whose service quality does not meet the service conditions can be deleted from the plurality of base stations included in the first consignment contract.

In one possible embodiment, the second server further transmits a toll rate contract to the terminal based on the high and low toll rates of the plurality of base stations, after the toll rate contract has been agreed upon. , The rate contract can be recorded in the target blockchain and the rate contract can be transmitted to at least one first server. Here, the second server can sort the charge rates of the plurality of base stations and generate a charge rate contract according to the charge rates of the sorted plurality of base stations. The second server can also add the quality of service of the plurality of base stations to the rate contract.

When a third consignment contract is added to the target blockchain, the second server is a terminal that further establishes a communication connection with the base station in the third consignment contract based on the third consignment contract. Is determined, and the updated charge rate instruction information can be transmitted to the terminal that has established a communication connection with the base station. As a matter of course, the plurality of second servers are further included in the first consignment contract based on the service quality of the base station in the third consignment contract and the service conditions in the first consignment contract. Base stations whose quality of service does not meet the service conditions can be deleted from the plurality of base stations.

Note that this step may be realized by a witness server among a plurality of servers. Correspondingly, the witness server generates a rate contract, sends the rate contract to a plurality of second servers, and the plurality of second servers validate the rate contract. If the verification is successful, the rate contract is recorded in the target blockchain. Here, the process of recording the rate contract on the target blockchain in the consensus building process based on the witness server is the same process as in step 306.

In step 702, the terminal establishes a communication connection with the target base station having the lowest charge rate among the plurality of base stations based on the charge rate instruction information.

The second server allocates the base station with the lowest charge rate to the terminal on the premise of guaranteeing the service quality of the base station based on the consignment contract in the target blockchain. In addition, by recording the charge rate contract in real time on the target blockchain and making the charge rate of the base station public and transparent, it is possible to charge the communication based on the charge rate contract after the agreement. The reliability of the source of data required for the billing process is guaranteed.

In the communication process between the terminal and the target base station, the target server can acquire the communication data amount of the terminal in real time, and the plurality of second servers form a consensus on the communication data amount. In the process of consensus building on the amount of communication data, the roles of the terminal, the plurality of second servers, and at least one first server are as follows.

Here, the data amount message includes an uplink communication data amount message and a downlink communication data amount message, and the uplink communication data amount message includes the communication data amount when the terminal performs uplink communication. The downlink communication data amount message includes the amount of communication data when the terminal performs downlink communication.

Here, the downlink communication means that the service server transmits the service data to the terminal via the first server in the core network, and the data flow direction during the downlink communication is from the service server to the core. It is transmitted to the terminal via the first server in the network and then through the target base station.

Uplink communication means that the terminal transmits service data to the service server via the first server in the core network, and the data flow direction during uplink communication is from the terminal to the target base station. Is transmitted to the service server via the first server in the core network.

(6-2), the plurality of second servers form an agreement on the amount of communication data in the target communication process of the terminal, and when the agreement is reached, the amount of the communication data is recorded in the target blockchain.

The target server among the plurality of second servers further verifies the data amount message based on the communication data amount in the target communication process of the terminal that the target server statistics, and verifies the data amount message. If successful, the data volume message is first signed, the first signed data volume message is transmitted to the plurality of second servers, and the plurality of second servers are said to be said. When an agreement is reached on the first signed data volume message, the first signed data volume message is recorded in the target blockchain. Here, the target server further determines that the public key is the same as the public key of the target server, based on the public key in the data volume message.

In one possible embodiment, the data volume message may be a second signed message by the terminal. Correspondingly, in the process in which the plurality of second servers form an agreement on the data amount message, the plurality of second servers further receive the data amount message of the target server and the terminal. The data amount message of the target server is verified by the public key of the target server, and when the verification of the data amount message of the target server is successful, the data amount message of the target server is recorded in the target blockchain.

As a matter of course, in the process of consensus building on the rate contract and putting it in the chain, the roles of the plurality of second servers and the witness server are the same as the consensus building process at the time of terminal registration.

In the embodiment of the present application, in the process of the terminal performing target communication with the target base station, the plurality of second servers acquire the communication data amount of the terminal in real time, and the communication data is successfully verified. By recording the amount in the target blockchain in real time, the plurality of second servers make communication charges publicly and transparently in the blockchain network based on the amount of communication data. Further, even if the target server maliciously falsifies the information in the data amount message by verifying the data amount message based on the second signature of the terminal by the plurality of second servers, the target server can perform the data amount message. Since the private key of the terminal cannot be known, the signature of the terminal in the data amount message cannot be tampered with. Therefore, even if the target server is maliciously tampered with, it can be easily detected by a plurality of second servers, and the accuracy of the data amount message is further guaranteed.

(6-3), the at least one first server further validates the data volume message in the target blockchain, and if the validation against the data volume message fails, a penalty policy for the target server. To carry out.

Here, the penalty policy includes subtracting the target numerical value from the communication charge distributed to the target server, or deleting the target server from the blockchain network. The at least one first server further generates a data amount message based on the communication data amount of the terminal, signs the data amount message, and sends the signed data amount message to the target server.

In one possible embodiment, the at least one first server further statistics the amount of communication data in the target communication process of the terminal.

In the above (6-1), the terminal transmits the uplink communication data amount message and the downlink communication data amount message as an example. In reality, in the process in which a plurality of second servers reach an agreement on the amount of communication data, the terminal sends an uplink communication data amount message for the amount of communication data to be agreed upon, and the first server May send a downlink communication data amount message, or the first server may send an uplink communication data amount message and a downlink communication data amount message. Correspondingly, in the process, the roles of the terminal, the plurality of second servers, and at least one first server may be as follows.

When the terminal sends an uplink communication data amount message and the first server sends a downlink communication data amount message,
(6-4), the terminal transmits an uplink communication data amount message to the plurality of second servers, and the uplink communication data amount message is sent to the uplink communication communication data amount in the target communication process of the terminal. And the public key of the target server.

The amount of communication data for downlink communication in the above and the public key of the target server are included.

(6-6), the plurality of second servers further form an agreement on the uplink communication data amount message of the terminal and form an agreement on the downlink communication data amount message of at least one first server. When the agreement on the uplink communication data amount message and the downlink communication data amount message is established, the uplink communication data amount message and the downlink communication data amount message are recorded in the target blockchain.

Alternatively, when the first server sends an uplink communication data amount message and a downlink communication data amount message,
(6-7), the at least one first server further sends a data volume message to the plurality of second servers.

Here, the data amount message includes an uplink communication data amount message and a downlink communication data amount message. The data amount message includes the amount of communication data in the target communication process of the terminal and the public key of the target server.

(6-8), the plurality of second servers further verify the data amount message of at least one first server, and if the verification is successful, the uplink communication data amount message and the downlink communication data. Record the volume message on the target blockchain.

In order to more clearly explain the billing process of the second server, the present embodiment exemplifies that the terminal transmits an uplink communication data amount message and a downlink communication data amount message. The process in which the server determines the amount of communication data will be described. FIG. 8 is a flowchart of a method in which the second server determines the amount of communication data, and as shown in FIG. 8, the method includes the following steps 801 to 804.

In step 801 the terminal sends a data volume message to the plurality of second servers.

Here, the terminal generates the data amount message based on the communication data amount in the target communication process of the terminal and the public key of the target server. In the target communication process, the terminal can periodically send a data amount message to the target server. In addition, the terminal can further sign the data amount message with the private key of the terminal.

In step 802, the target server verifies the data amount message based on the amount of communication data in the target communication process of the terminal that the target server has statistic, and if the verification for the data amount message is successful, the data. The amount message is first signed, and the first signed data amount message is transmitted to the plurality of second servers.

Here, the terminal and the target server can synchronously statistic the communication data amount of the terminal, and when the terminal sends a data amount message to a plurality of second servers in the blockchain network. The target server among the plurality of second servers determines that the data amount message is a data amount message when the communication service is provided by the target base station based on the public key in the data amount message. decide.

In one possible embodiment, the at least one first server can further stat the amount of communication data in the target communication process of the terminal. If the target server fails to verify the data volume message or has not received the data volume message, the target server receives communication data from the at least one first server in the target communication process of the terminal. Get the quantity.

Here, in the process of periodically transmitting the data amount message by the terminal, the transmission is suddenly interrupted, so that the target server does not receive the data amount message, or the target server responds to the data amount message. If the verification fails, the target server can acquire the communication data amount of the terminal from the first server. Here, the first server can generate a data amount message based on the communication data amount of the terminal, sign the data amount message, and send the signed data amount message to the target server. .. The target server second-signs the data volume message, sends the second signed data volume message to a plurality of second servers, and the second signed data volume. If the verification of the message by the plurality of second servers is successful, the data amount message for which the verification is successful is recorded in the target blockchain.

In step 803, the plurality of second servers form a consensus on the data volume message transmitted from the target server.

The plurality of second servers can verify the data amount message with the public key of the target server. In one possible embodiment, if the data volume message includes a second signature of the terminal, the plurality of second servers further validate the data volume message based on the terminal's public key. Then, it is possible to determine whether or not the data amount message has been maliciously tampered with, and if it is verified that the data amount message has not been maliciously tampered with, record the data amount message in the target blockchain. can.

Actually, this step is an embodiment in which the plurality of second servers verify the amount of communication data in the target communication process of the terminal, and as a matter of course, the plurality of second servers further include.

In step 901, when the verification of the communication data amount of the terminal is successful, the plurality of second servers are based on the communication data amount and the charge rate of the target base station recorded in the target blockchain. The communication charge data of the terminal is determined.

This step may be executed by a plurality of second servers, or may be executed by a witness server among the plurality of second servers. Taking the witness server as an example, the witness server determines the communication data amount of the terminal based on the data amount message in the target blockchain, and the communication data amount and the target acquired by the target blockchain. The communication charge data in the target communication process of the terminal is determined based on the charge rate of the base station.
