Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a service resource metering method, a service resource metering device, an electronic device, and a computer-readable storage medium. Background Technology

[0002] Near-field communication (NFC) is an emerging communication technology that allows user terminals to connect to other user terminals wirelessly and connect to the Internet by using other user terminals as relay devices. It effectively solves the problem of insufficient mobile communication coverage in certain scenarios and is an important component of the development of 5G and even 6G mobile communication technologies.

[0003] Generally, multiple relay devices may need to be set up between the user terminal and the Internet. In order to ensure that each relay device in the local area communication network can provide stable services, an effective incentive mechanism needs to be established to measure the services provided by the relay devices and give rewards such as points.

[0004] Currently, the common practice is to upload the traffic data generated by relay devices to a blockchain network each time, where smart contracts calculate the specific settlement fees. However, considering the ever-expanding node scale of near-field communication networks, a large amount of traffic data needs to be recorded on the blockchain between adjacent relay nodes, between end users and relay nodes, and between relay nodes and operators, putting significant pressure on the blockchain's data capacity.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this disclosure is to provide a service resource metering method, a service resource metering device, an electronic device, and a computer-readable storage medium, thereby at least to a certain extent reducing the load pressure on the blockchain network and improving the service resource metering efficiency of each node in the near-field communication network.

[0007] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[0008] According to a first aspect of the present disclosure, a service resource metering method is provided, performed by a first relay communication device in a near-field communication network, the method comprising:

[0009] Obtain verification information of the second relay communication device accessing the near-field communication network, and establish a local metering channel based on the verification information;

[0010] The local metering channel will be used to reach a consensus on the first service resource metering value and the second service resource metering value provided by the second relay communication device.

[0011] The consensus-reached first service resource metering value is stored in the first off-chain ledger, and at the same time, the second relay communication device stores the consensus-reached second service resource metering value in the second off-chain ledger.

A local metering channel can be established between the first and second relay communication devices in a near-field communication network. The frequent traffic between them can be separately recorded and consensused through the local metering channel. When the local metering channel ends, all service resource metering values ​​in all ledgers are settled into a total value and submitted to the blockchain network to complete the final transaction. This effectively reduces the blockchain load problem caused by putting various trivial traffic on the chain, effectively reduces the load pressure on the blockchain network, and improves the service resource metering efficiency of each node in the near-field communication network.

[0062] Figure 1 The diagram schematically illustrates an architecture of a near-field communication network that can be used in embodiments of this disclosure.

[0063] refer to Figure 1 As shown, the near-field communication network can be composed of at least user terminal 101, user terminal 102, relay communication device 103, relay communication device 104, and relay communication device 105. Relay communication device 103 can be connected to the uplink network via mobile base station 106, relay communication device 104 can be connected to the uplink network via mobile base station 107, and relay communication device 105 can be connected to the uplink network via broadband network 108. Of course, the connection methods between user terminals and relay communication devices, between relay communication devices, and between relay communication devices and the Internet are merely illustrative and can be any other arbitrary connection methods, and should not impose any special limitations on this example embodiment.

[0064] Generally, a near-field communication (NFC) system mainly includes two types of participating nodes. One type consists of terminal devices that provide network connectivity services, called relay communication devices, such as relay communication devices 103, 104, and 105. The other type consists of user terminals connected to the internet through relay communication devices, such as user terminals 101 and 102. Typically, the simplest NFC network configuration involves relay communication devices directly connecting to the internet via cellular mobile communication. User terminals then connect to the relay communication devices via wireless technologies such as Wi-Fi, and subsequently connect to the internet through the cellular communication or broadband network connected by the relay communication devices. For example, user terminal 101 connects to relay communication device 103, and relay communication device 103 connects to mobile base station 106, enabling user terminal 101 to connect to the internet. This is the most typical and simplest networking method, which is most evident in the early stages of technology and business development. As NFC technology develops, it will continuously expand and upgrade in various dimensions, specifically in several aspects:

[0065] (1) Number of relay hops. As the business develops, the demand for areas lacking wireless network access will increase, or due to major emergencies, there will be more and more scenarios where a large number of accesses will suddenly increase in a specific area. Therefore, single-hop relays often cannot fully meet the needs of the business, and multiple relay communication devices will be connected in series to jointly serve a single user's Internet access.

[0066] (2) Relay Type. With the continuous development of near-domain service traffic, simply using mobile terminals such as smartphones as relay communication devices often cannot meet users' demands for high-quality services. For example, insufficient battery power, unstable signals due to frequent movement, overheating under high traffic volumes, and high costs are common problems. In this situation, professionals will set up more specialized relay communication equipment to provide services and earn relay service fees. For example, this professional relay type might be a hardware box fixed in a specific location, retaining only the necessary relay communication functions and blockchain wallet functions, achieving low cost, high stability, and high bandwidth simultaneously.

[0067] (3) Uplink network. Near-field communication is no longer limited to allowing relay equipment to access cellular mobile networks. It is possible to simultaneously access broadband networks or even satellite networks. Relay communication equipment can choose to access faster networks to provide services to user terminals.

[0068] With these changes, more users will join local area communication networks to act as relay communication devices long-term and stably, providing professional relay services similar to those of mobile operators, thereby generating service revenue. However, due to cost limitations, these relay services will gradually develop a division of labor in terms of coverage. For example, relay communication device 103 or 104 may be closer to mobile base station 106 or 107, while another relay communication device 105 may be closer to broadband network 108 (such as providing broadband via Wi-Fi). Relay communication devices 103 or 104 can establish a connection channel with relay communication device 105 to bridge their traffic. Thus, when a user accesses a website, if the cellular network is faster, they can directly access the website through relay communication device 103 or 104; if the broadband network is faster, they can connect to relay communication device 105 through relay communication device 103 or 104 to access the website. This situation will occur frequently, especially during sudden surges in live streaming traffic. Distributing traffic across different networks will significantly increase access volume and reduce congestion on various access networks. In addition to coverage division, as relay communication equipment becomes more stable and relay bandwidth continues to increase, expanding internet coverage through multi-hops is a highly cost-effective approach, greatly reducing the costs for operators to build base stations and lay fiber optic cables.

[0069] This type of network, formed by the self-organizing connection of relay devices, is similar in network topology and traffic routing to a network formed by the interconnection of various routers from an operator. It is very common for relays to provide services to each other, acting as upstream and downstream partners. For example... Figure 1 As shown, relay communication devices 103, 104 and 105 are connected to different uplink networks, and they are connected in series to form a self-organizing network. User terminal 101 and user terminal 102 can connect to the Internet through adjacent relay communication devices, and can also communicate with each other through this self-organizing network.

[0070] To ensure stable service provision by relay communication devices in a near-field communication network, an effective incentive mechanism is needed to measure the service resources provided by these devices and award points or similar rewards based on the measured values. Blockchain can record service measurement data confirmed by multiple parties through a consensus mechanism, automatically distributing point rewards without requiring trust in a third party. In a blockchain-based model, the number of services provided by relay communication devices to downstream user terminals will be measured, and the measured service quantity will be written into the blockchain. A blockchain smart contract will then provide the specific settlement fee, and points will be sent to the relay service provider's blockchain account at the same time. The services measured here mainly refer to common traffic services or time-based services, with traffic services being the most common measurement method; the following descriptions will primarily use traffic services.

[0071] Blockchain technology is an immutable technology; all data recorded on the blockchain network is preserved. As metering data is periodically written to the blockchain, the amount of data on the blockchain continuously expands. Considering the ever-expanding scale of nodes in near-field communication networks, there will be a constant flow of metering data that needs to be uploaded to the blockchain between adjacent relay nodes, between end users and relay nodes, and between relay nodes and operators. This places significant pressure on the blockchain network. Furthermore, since blockchain ledger resources are inherently scarce, and metering data often loses value over time, utilizing various optimization techniques to improve blockchain efficiency while ensuring fairness among all participants in near-field communication networks is an important research direction.

[0072] Based on this, in this example embodiment, a service resource metering method is first provided. This service resource metering method can be executed by a first relay communication device in a near-field communication network, such as by... Figure 1 The relay communication equipment 103, relay communication equipment 104 or relay communication equipment 105.

[0073] Figure 2 A schematic flowchart illustrating a service resource metering method according to some embodiments of the present disclosure is shown below. Figure 2 The steps in this example further illustrate the service resource metering method in this embodiment.

[0074] In step S210, the verification information of the second relay communication device accessing the near-field communication network is obtained, and a local metering channel is established based on the verification information.

[0075] In one example embodiment of this disclosure, the second relay communication device refers to a terminal device near the first relay communication device that can provide network relay services. For example, the first relay communication device may be... Figure 1The relay communication device 103 in the middle, the second relay communication device can be Figure 1 The relay communication device 104 or relay communication device 105 can be used, or it can be both relay communication device 104 and relay communication device 105. This example embodiment does not make any special limitation on this. The first relay communication device can search for the second relay communication device within a certain range through wireless signals or wireless search services.

[0076] It should be noted that in this embodiment, the terms "first" and "second" in "first relay communication device" and "second relay communication device" are only used to distinguish different relay communication devices and have no special meaning. They should not impose any special limitations on this example embodiment.

[0077] Verification information refers to data used to prove the identity of the second relay communication device. For example, verification information can be the identity document (unique identifier) ​​of the second relay communication device or the public key address of the second relay communication device. This example embodiment does not impose any special limitations on this.

[0078] A Public Key Infrastructure (PKI) system can be pre-created on the blockchain network to perform real-name user authentication for each relay communication device and user terminal accessing the near-field communication network. The identity document (ID) and corresponding public key address of each relay communication device and user terminal are recorded on the blockchain network. After the first relay communication device detects the second relay communication device, it can obtain the verification information corresponding to the second relay communication device through the PKI system on the blockchain network.

[0079] A local metering channel refers to an off-chain channel created to statistically analyze the service resource values ​​provided by relay communication devices during cooperation. By establishing local metering channels between relay communication device nodes, the service resources provided by the cooperating relay communication devices are effectively measured, while ensuring that the measured service resource values ​​do not cause a large data load on the blockchain network.

[0080] In step S220, consensus is reached on the first service resource metering value and the second service resource metering value provided by the second relay communication device based on the local metering channel.

[0081] In one example embodiment of this disclosure, the first service resource metering value refers to the service resource provision value statistically calculated locally by the first relay communication device. The first service resource metering value may include the uplink and downlink traffic from the first relay communication device to the second relay communication device. The second service resource metering value refers to the service resource provision value statistically calculated locally by the second relay communication device. The second service resource metering value may include the uplink and downlink traffic from the second relay communication device to the first relay communication device.

[0082] A predetermined metering period and method can be used to statistically analyze the first service resource metering value and obtain the second service resource metering value provided by the second relay communication device, as well as a pre-determined metering deviation threshold. Then, when the deviation between the first and second service resource metering values ​​is within an acceptable tolerance range, the second service resource metering value is digitally signed using private key information and returned to the second relay communication device for storage in the corresponding second off-chain ledger, thus completing the consensus on the second service resource metering value. Similarly, the second relay communication device can also statistically analyze the second service resource metering value and obtain the first service resource metering value provided by the first relay communication device. When the deviation between the first and second service resource metering values ​​is within an acceptable tolerance range, the first service resource metering value is digitally signed using private key information and returned to the first relay communication device for storage in the corresponding first off-chain ledger, thus completing the consensus on the first service resource metering value.

[0083] In step S230, the consensus-reached first service resource meter value is stored in the first off-chain ledger, and at the same time, the second relay communication device stores the consensus-reached second service resource meter value in the second off-chain ledger.

[0084] In one example embodiment of this disclosure, the first off-chain ledger refers to the local ledger corresponding to the first relay communication device, and the second off-chain ledger refers to the local ledger corresponding to the second relay communication device. After reaching consensus on the first service resource metering value and the second service resource metering value each time, the service resource metering value is consensused through the local metering channel and does not need to be uploaded to the blockchain network. Only after the current service ends and the local metering channel ends is the aggregated service resource metering value uploaded to the blockchain network for service resource settlement. This effectively reduces the problem of uploading fragmented service resource data to the blockchain network multiple times, reduces the load pressure on the blockchain network, and improves the metering efficiency of service resources.

[0085] In step S240, in response to the local metering channel meeting the termination condition, the first off-chain ledger is uploaded to the blockchain network, and / or the second off-chain ledger is uploaded to the blockchain network by the second relay communication device, so that the blockchain network completes service resource settlement based on the first off-chain ledger and / or the second off-chain ledger, and closes the local metering channel.

[0086] In one example embodiment of this disclosure, the termination condition of the local metering channel may be the arrival of the local metering channel's termination time, or the receipt of a request from the first relay communication device or the second relay communication device to actively interrupt the local metering channel. Of course, other types of termination conditions may also apply, and this example embodiment is not limited thereto.

[0087] When the termination condition is the arrival of the local metering channel's end time, the first relay communication device and the second relay communication device can simultaneously upload the first off-chain ledger and the second off-chain ledger to the blockchain network; when the termination condition is the first relay communication device actively interrupting the local metering channel's request, the first relay communication device can upload the first off-chain ledger to the blockchain network; when the termination condition is the second relay communication device actively interrupting the local metering channel's request, the second relay communication device can upload the second off-chain ledger to the blockchain network; this embodiment does not impose special limitations on the method of uploading the off-chain ledger.

[0088] The blockchain network can verify the service resource incentives based on the uploaded first and / or second off-chain ledgers. After successful verification of the first and / or second off-chain ledgers, the transfer of service resource incentives can be determined based on the first and / or second service resource measurement values ​​recorded in the first and / or second off-chain ledgers. For example, the service resource incentives can be service resource points or other service incentives that can be transferred in the blockchain wallet. This example embodiment does not impose any special limitations on the type of service resource incentives.

[0089] Steps S210 to S240 will be described in detail below.

[0090] In one example embodiment of this disclosure, the blockchain network may include smart contracts for managing local metering channels, and a public key infrastructure system; specifically, it can be achieved through... Figure 3 The steps in the document are as follows to establish a local metering channel:

[0091] Step S310: Send a channel establishment request to the second relay communication device, the channel establishment request including first smart contract information;

[0092] Step S320: Receive request response information returned by the second relay communication device in response to the channel establishment request, wherein the request response information includes second smart contract information created based on the first smart contract information;

[0093] Step S330: Obtain the public key information of the second relay communication device from the public key infrastructure system, and verify the signature of the second smart contract information based on the public key information;

[0094] Step S340: Broadcast the second smart contract information after signature verification to the blockchain network, so that the blockchain network can create a local metering channel based on the second smart contract information and the smart contract for managing the local metering channel.

[0095] The channel establishment request may include first smart contract information, and a digital signature of the first smart contract information by the first relay communication device using the first private key information.

[0096] Specifically, the first smart contract information may include the first identity identifier of the first relay communication device, the start and end time of the local metering channel, the first service resource points available for pledging by the first relay communication device, the metering period, the metering method, and the uplink network information of the first relay communication device.

[0097] The request response information may include second smart contract information created based on the first smart contract information, and a digital signature of the second smart contract information by the second relay communication device using the second private key information.

[0098] Specifically, the second smart contract information may include the first smart contract information verified by the second relay communication device (refer to the description of the first smart contract information in the channel establishment request, which will not be repeated here), as well as the second identity identifier of the second relay communication device, the second service resource points available for staking, and the uplink network information of the second relay communication device. The request response information also includes the digital signature of the second smart contract information by the second relay communication device through the second private key information.

[0099] The first relay communication device can search for a second relay communication device within a certain range using wireless signals or a wireless search service. Upon determining that a local metering channel needs to be established with the second relay communication device, it can send a channel establishment request to the second relay communication device and receive a response from the second relay communication device. It can obtain the public key information of the second relay communication device from the public key infrastructure system, and then verify the signature of the second smart contract information in the response information based on the public key information. Furthermore, it can broadcast the verified second smart contract information to the blockchain network, enabling the blockchain network to create a local metering channel based on the second smart contract information and the smart contract managing the local metering channel.

[0100] In one example embodiment of this disclosure, it can be achieved through Figure 4 The steps in the process achieve consensus on the statistical values ​​of the first service resource and the second service resource provided by the second relay communication device based on the local metering channel, referencing... Figure 4 As shown, it can specifically include:

[0101] Step S410: Based on the metering period and metering method recorded in the smart contract, calculate the metering value of the first service resource;

[0102] Step S420: Obtain the second service resource metering value provided by the second relay communication device, and obtain the metering deviation threshold determined by pre-consensus.

[0103] Step S430: If it is determined that the deviation between the first service resource metering value and the second service resource metering value is less than or equal to the metering deviation threshold, then the second service resource metering value is digitally signed using the first private key information and returned to the second relay communication device to complete the consensus.

[0104] The metering period refers to the pre-set periodic statistical service resource value data. For example, the metering period can be 1 hour or 30 minutes, and this example embodiment does not make any special limitation on it. The metering method refers to the pre-set type of statistical service resource value. For example, the metering method can be based on traffic data or based on service duration, and this example embodiment does not make any special limitation on it.

[0105] The metering deviation threshold refers to a pre-set tolerable deviation range. For example, the metering deviation threshold can be the deviation range of service resource values, such as 10% or 5%. Of course, the metering deviation threshold can also be a specific difference threshold of service resource values, such as 100MB of traffic or 50MB of traffic. The specific threshold can be agreed upon according to the actual application situation. This example embodiment does not make any special limitations on this.

[0106] The first service resource metering value includes the uplink and downlink traffic from the first relay communication device to the second relay communication device. Of course, if data redundancy is not considered, the first service resource metering value may also include the uplink and downlink traffic from the second relay communication device to the first relay communication device. This example embodiment does not make any special limitation on this.

[0107] The second service resource metering value includes the uplink and downlink traffic from the second relay communication device to the first relay communication device. Of course, if data redundancy is not considered, the second service resource metering value may also include the uplink and downlink traffic from the first relay communication device to the second relay communication device. This example embodiment does not make any special limitation on this.

[0108] For example, assuming the billing cycle agreed upon between the first and second relay communication devices is one hour, and the billing method is traffic-based billing, then every hour, both the first and second relay communication devices will calculate the uplink traffic F(AB↑) from the first relay communication device to the second relay communication device within that hour. The second relay communication device will digitally sign the calculated traffic value (via wireless communication through its local metering channel) and send it to the first relay communication device. The first relay communication device will compare this value with its locally recorded traffic value. If the difference is within acceptable limits, it will sign the value again and send it to the second relay communication device. The second relay communication device will store the signed value from the first relay communication device in its local second off-chain ledger, and the first relay communication device will also store the signed value from the second relay communication device in its local first off-chain ledger. If the first relay communication device finds a significant difference between the value sent by the second relay communication device and its locally recorded traffic value, it will choose to renegotiate with the second relay communication device or terminate the local channel according to its local policy. Similarly, every hour, the first and second relay communication devices will calculate the downlink traffic F(AB↓) from the first relay communication device to the second relay communication device, the uplink traffic F(BA↑) from the second relay communication device to the first relay communication device, and the downlink traffic F(BA↓) from the second relay communication device to the first relay communication device within the hour. After reaching a consensus in the aforementioned manner, they will store the data in their local off-chain ledger.

[0109] In one example embodiment of this disclosure, the liquidation of service resources can be achieved through the following steps:

[0110] It can respond to a channel interruption request from at least one of the first and second relay communication devices, or trigger the end time of the local metering channel, to upload the first off-chain ledger to the off-chain storage location, and / or have the second relay communication device upload the second off-chain ledger to the off-chain storage location; then it can send settlement information to the blockchain network so that the verification nodes in the blockchain network can access the first and / or second off-chain ledgers in the off-chain storage location according to the settlement information and complete the service resource settlement;

[0111] The liquidation information may include the first and second service resource metering values ​​within the lifecycle of the local metering channel, the complete off-chain storage address of the first off-chain ledger, and the complete hash value of the first off-chain ledger. Alternatively, if the liquidation information is initiated by a second relay communication device, it may include the first and second service resource metering values ​​within the lifecycle of the local metering channel, the complete off-chain storage address of the second off-chain ledger, and the complete hash value of the second off-chain ledger. The specific liquidation information is related to the initiating device, and this example embodiment does not impose any special limitations on it.

[0112] Off-chain storage location refers to the storage location that can be accessed by the verification nodes in the blockchain network. For example, off-chain storage location can be a centralized storage location or a decentralized storage location. This example embodiment does not make any special limitation on this.

[0113] For example, suppose the first relay communication device wants to interrupt its local channel with the second relay communication device for some reason (such as distrust of the second relay communication device's service metering data or inability to continue providing service due to its own reasons). The first relay communication device sends a channel interruption request to the blockchain network. The smart contract managing the local metering channel in the blockchain network will, based on the first relay communication device's request, change the relevant local metering channel from a normal established state to a liquidation state. In the liquidation state, both the first and second relay communication devices can submit necessary liquidation information to the blockchain network's smart contract. For example, the first relay communication device can first store the complete first off-chain ledger, which records the metering values ​​of each service resource (F(AB↑), F(AB↓), F(BA↑), and F_(BA↓)) (each containing the signatures of both parties), in an off-chain storage location accessible to the verification nodes of the blockchain network (this can be a centralized or decentralized storage location; considering data security and fairness, the latter is generally chosen). Then, it submits some necessary settlement information, digitally signed by the first relay communication device, to the blockchain smart contract. The settlement information can include: the total of all traffic for F(AB↑), F(AB↓), F(BA↑), and F(BA↓) during the entire local channel lifecycle (4 values); the off-chain storage address corresponding to the complete first off-chain ledger; and the hash value of the complete first off-chain ledger.

[0114] Optionally, the verification nodes in the blockchain network can be used to obtain the first off-chain ledger and / or the second off-chain ledger from the off-chain storage location according to the off-chain storage address in the liquidation information, and transfer the first service resource points and the second service resource points pledged in the blockchain network by the first relay communication device and the second relay communication device according to the first service resource measurement value and / or the second service resource measurement value recorded in the first off-chain ledger and / or the second off-chain ledger, thereby completing the service resource liquidation.

[0115] Optionally, the verification nodes in the blockchain network can also be used to compare the first off-chain ledger and the second off-chain ledger when they receive an objection request from the first relay communication device or the second relay communication device, and arbitrate the objection request based on the comparison result, and complete the settlement of service resources.

[0116] For example, during the settlement phase, if the second relay communication device disagrees with the traffic total information of the first relay communication device, it can raise an objection during this period. Assuming the second relay communication device sees the interruption request from the first relay communication device before the settlement phase ends, and disagrees with the traffic total information submitted by the first relay communication device, it can also store the complete second off-chain ledger, recording each value of F(AB↑), F(AB↓), F(BA↑), and F(BA↓) (each containing the signatures of both parties), in an off-chain storage location accessible to validator nodes in the blockchain network. Then, it provides the smart contract with the four traffic totals mentioned above, the ledger storage address of the complete second off-chain ledger, and the hash value of the complete second off-chain ledger. Upon discovering a dispute between the first and second relay communication devices, the validator nodes retrieve the corresponding complete first or second off-chain ledger through the provided ledger storage address, compare the off-chain ledgers, and determine the party with more complete ledger information wins, thus completing the arbitration of the dispute and the final settlement of points.

[0117] During the settlement period, the first relay communication device, which actively interrupts the local metering channel, can provide settlement information first. If the second relay communication device agrees, it does not need to submit settlement information again; it can end the settlement period by directly submitting a message of agreement to the blockchain or wait until the maximum waiting time ends. After the settlement period ends, the blockchain network directly calculates the net flow value and corresponding final point change value in each network data transmission direction between the first and second relay communication devices based on the settlement information provided by the first relay communication device. It then completes the transfer of these changed points between the accounts of the first and second relay communication devices, unlocks the staked points in each account, and terminates the local metering channel. If the second relay communication device disagrees with the first relay communication device's settlement information during the settlement period, it will submit its own settlement information separately. After the settlement period ends, the blockchain network will compare the complete ledgers provided by both parties to determine whose information is more accurate, and then complete the point transfer based on this information, terminating the local channel. If the first relay communication device delays submitting settlement information during the settlement period, the second relay communication device can also submit its own settlement information first to ensure effective settlement. If neither the first relay communication device nor the second relay communication device submits settlement information during the settlement period, the points in both accounts will be automatically unlocked, and no points will be transferred.

[0118] Figure 5 The diagram illustrates a framework of a service resource metering system that can be applied to embodiments of this disclosure.

[0119] refer to Figure 5As shown, the service resource metering system may consist of a blockchain network, relay communication device A, relay communication device B, a local metering channel between relay communication device A and relay communication device B, and off-chain storage locations.

[0120] The blockchain network can include smart contracts that manage local metering channels and a public key infrastructure (PKI) system. Relay communication devices A and B can obtain status information related to the local metering channels from the blockchain network and create local metering channels using the status information. They can also send transaction information related to the operation of local metering channels to the blockchain network. For example, transaction information can include channel interruption requests, objection requests, and settlement information. When the local metering channel meets the termination conditions, relay communication devices A and B upload their local off-chain ledgers to the off-chain storage location. The verification nodes of the blockchain network then retrieve the complete off-chain ledger from the off-chain storage location based on the ledger storage address in the settlement information and complete the settlement or arbitration objection request for service resources between relay communication devices A and B.

[0121] Figure 6 The illustration shows a schematic diagram of the state transition of a local metering channel in a smart contract according to some embodiments of the present disclosure.

[0122] refer to Figure 6 As shown, in this embodiment, the states set by the blockchain smart contract for the local metering channel can include initial state 601, establishment state 602, settlement state 603, and deletion state 604. After the blockchain network receives a transaction message in which both parties have signed and agreed to establish a local metering channel, the initial state 601 is transitioned to the establishment state 602; when at least one party sends a request to actively terminate the local metering channel or the agreed end time of the local metering channel is reached, the establishment state 602 is transitioned to the settlement state 603; when the maximum waiting time for settlement expires or both parties agree to actively end the settlement phase, the settlement state 603 is transitioned to the deletion state 604, and the current local metering channel is terminated.

[0123] In summary, the service resource metering method in this example embodiment can establish a local metering channel between the first and second relay communication devices in a near-field communication network. This local metering channel is used to separately record and reach consensus on frequent traffic flows between them. Once the local metering channel is closed, all service resource metering values ​​in all ledgers are settled into a single total value and submitted to the blockchain network to complete the final transaction. This effectively reduces the blockchain load caused by uploading various fragmented traffic flows to the blockchain, effectively reduces the load pressure on the blockchain network, and improves the service resource metering efficiency of each node in the near-field communication network.

[0124] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.

[0125] Furthermore, in this example embodiment, a service resource metering device is also provided, which is installed in a first relay communication device in a near-field communication network.

At the same time, the second relay communication device stores the second service resource metering value after consensus into the second off-chain ledger.

[0129] The service resource clearing module 740 is used to respond to the local metering channel meeting the termination condition by uploading the first off-chain ledger to the blockchain network, and / or by uploading the second off-chain ledger to the blockchain network by the second relay communication device, so that the blockchain network completes service resource clearing based on the first off-chain ledger and / or the second off-chain ledger, and closes the local metering channel.
