Description

Edge intercommunication service execution method, device, system, electronic device and medium

This disclosure claims priority to Chinese patent application number 202211194116.4, filed on September 28, 2022, and entitled “Edge intercommunication service execution method, device, system, electronic device and medium”, the entire contents of which are incorporated herein by reference.

Technical Field

The present disclosure relates to the field of blockchain technology, and in particular to an edge intercommunication service execution method, an edge intercommunication service execution device, an edge intercommunication service execution system, an electronic device, and a storage medium.

Background technique

In the service ecosystem of edge computing, there are various service providers such as network operators, edge cloud service providers, and application providers. In different edge environments, the parties that provide services may be different. In order to ensure the reliability of end-user experience of edge services, GSMA (Global System for Mobile Communications Association) proposed the concept of operator platform OP (Operator Platform), hoping to introduce the functional entity of OP and standardize a series of interoperability interfaces, so that OP can become an intermediary and interconnection platform for different service providers to achieve ecological co-construction. However, since OP does not have a recognized and interest-decoupled operator, the fairness and justice of cooperative operation is questioned, which in turn leads to the inability to provide users with optimal service solutions.

It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

Detailed ways

Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and/or processor devices and/or microcontroller devices.

As shown in Figure 1, in the currently defined OP architecture, the OO platform has features such as capability exposure, alliance management, and service resource management, and contracts cooperation through standardized interfaces. Each provider has its own OP, and the main functions of OP include: southbound control, calling various resources and capabilities; northbound opening of various resources and network capabilities, providing application deployment and monitoring interfaces; east-west federation intercommunication management, and application image, application metadata transmission and management collaboration.

In addition, OP provides the following interfaces: SBI-NR (network resource southbound interface), SBI-CR (cloud resource southbound interface), SBI-CHF (billing function southbound interface), EWBI (east-west interface, intercommunication between OPs), NBI (northbound interface, used to open capabilities to applications) and UNI (user-network interface). Based on the above interfaces, network connections with each sub-OP (including OP1, OP2 and OP3, etc.), as well as application providers, cloud resource providers, network resource providers, billing engines and clients are realized.

This architecture currently has the following defects: on the one hand, since the selection of partners is completely determined unilaterally by the OP, it is impossible to review the rationality from the perspective of user experience; on the other hand, the cooperation process cannot be effectively held accountable. If one party does not keep its word, it may lead to damage to the interests of the other party.

The solution provided by the present application is that, in a blockchain network including a first operating platform and a second operating platform, when the first operating platform receives a business request of an edge application sent by a terminal, the first operating platform executes a query operation of a matching business solution on the blockchain based on a smart contract to find out matching application deployment requirements and cloud resources, and based on the matching result, determines a second operating platform that has deployed or can deploy the edge application, so that the second operating platform can provide edge application services, and further generates a network access policy for accessing the edge application based on its own network resources, and sends the network access policy to the terminal, so that the terminal establishes a network connection with the edge cloud where the edge terminal is located, so that a better service solution that meets the business request can be configured based on the resources shared on the blockchain. On the one hand, it is conducive to improving the user's access experience to the edge application, and on the other hand, it can also ensure the fairness of the service solutions determined by the cooperation of multiple operating platforms, and prevent the phenomenon that some resource providers provide non-optimized service solutions based on their own interests.

Hereinafter, each step of the edge intercommunication service execution system and the edge intercommunication service execution method in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

As shown in FIG2 , an edge intercommunication service execution system according to an embodiment of the present disclosure includes: a blockchain includes a first operation platform, a second operation platform and a third operation platform.

As shown in FIG. 2 , an edge intercommunication service execution system according to another embodiment of the present disclosure includes a blockchain network, wherein the blockchain network includes a first operation platform OP1 corresponding to a network resource provider, a second operation platform OP2 corresponding to a cloud resource provider, and a third operation platform OP3 corresponding to an application provider, wherein the first operation platform OP1 is used to publish shared network resources in the blockchain and perform network resource management, the second operation platform OP2 is used to publish shared cloud resources in the blockchain and perform cloud resource management, and the third operation platform OP3 is used to publish shared application deployment requirements in the blockchain and perform application requirement management, and the application deployment requirements further include cloud resource requirements and network requirements.

Specifically, the network resources released by the first operating platform OP1 include but are not limited to: service area, cloud resource connection information and network open capability information.

The cloud resources and edge platforms released by the second operating platform OP2 include but are not limited to: service areas, computing resources, and storage resources;

The application deployment requirements released by the third operating platform OP3 include but are not limited to: network QoS, computing resources, storage resources and capability calling requirements.

In addition, each operating platform stores smart contracts for implementing edge application business requests.

In the process of executing edge intercommunication services, the first operation platform is used to respond to the service request of the edge application sent by the terminal, query the cloud resource requirements and network requirements matching the service request on the blockchain based on the deployed smart contract, and initiate the service transaction on the blockchain.

The second operating platform is used to deploy, select or adjust edge applications on the matching edge cloud based on smart contracts and cloud resource requirements, and initiate business transactions on the blockchain.

The first operation platform is also used to: generate a network access policy for the terminal to access the edge application based on the smart contract and network requirements, and send the network access policy to the terminal so that the terminal can establish a network connection with the edge cloud based on the network access policy, so that the terminal can access the edge application.

Specifically, the first operation platform OP1, the second operation platform OP2 and the third operation platform OP3 are constructed as network nodes in the blockchain network. In the present disclosure, by adopting multiple operation platforms as nodes to construct a chain structure, multiple operation platforms can share the resources or information published by the network provider, the cloud resource provider and the application provider respectively, so that when the edge application service request sent by the terminal 206 is received, matching resources can be configured for the edge application service.

In addition, the first operating platform OP1, the second operating platform OP2 and the third operating platform OP3 can also be nodes at the edge of the network, that is, edge nodes. By downlinking the edge intercommunication service to the operating platform, the data or service of the application is transferred from one or more central nodes to the edge node. On the one hand, it can effectively reduce the delay of the computing system, reduce the data transmission bandwidth, relieve the pressure of the cloud computing center, improve availability, and protect data security and privacy. On the other hand, using the operating platform as a blockchain node and an edge node, resource sharing of multiple providers is realized. Based on the shared resource configuration and the smart contract of the blockchain, the configuration of the optimal execution plan for the edge intercommunication service is realized.

Those skilled in the art can understand that the business requests of edge applications are used to request edge services executed based on edge nodes, mainly to provide local services to meet the requirements of real-time, cost, security and privacy protection. The services of edge applications include but are not limited to: data collection, message parsing or protocol parsing, data cleaning or filtering, local scene linkage, analysis and alarm, data recording, video preprocessing or video analysis, voice preprocessing or voice analysis, local machine learning, and function computing.

In addition, the smart contract can be understood as a functional module that determines the edge intercommunication service resources that best match the service request. In this disclosure, the functions completed by the smart contract include but are not limited to:

(1) Evaluate the service resources and application requirements and compatibility of the service area based on the application request, and match the optimal combination.

(2) Triggering application enablement of cooperative OPs (transferring application images between OPs, integrating and instantiating applications on the cloud, building UE service policies and feeding back to UEs, and transferring management information such as billing and monitoring between OPs).

(3) Confirmation of ownership of shared resources.

(4) Record the resource sharing status on the chain and control the shared life cycle, and update the resource and application demand data on the blockchain through the consensus process.

Furthermore, the first operating platform OP1 is respectively connected to the network resource provider, the client and the billing engine for communication.

The second operation platform OP2 is communicated with the cloud resource provider and the billing engine respectively.

The third operating platform OP3 is communicated with the application provider and the billing engine respectively.

In this embodiment, the federal management function of OP is executed by the smart contract of the blockchain network. Based on the smart contract, the cooperation process can be automatically executed towards the preset goal while ensuring fairness and credibility.

Furthermore, based on the edge intercommunication service execution system disclosed in the present invention, the functions of OP can be simplified. Specifically, the provider's own management system can be used to undertake the OP.

By adopting the OPs of each provider to form a consortium chain, network providers and cloud service providers publish their sharable resources on the blockchain through their respective OPs, and application providers publish their application deployment requirements and business requirements on the blockchain through their respective OPs. By reaching a consensus on the collaboration goals among all partners, the optimization of the business experience is guaranteed.

Specifically, relevant strategies are deployed in the form of smart contracts. When there is a business request, the smart contract automatically matches supply and demand and triggers related operations of resource allocation and application deployment, and records shared indicators on the blockchain in the form of transactions.

In addition, in order to prevent the performance impact caused by storing too much data on the blockchain, a combination of on-chain and off-chain storage can be adopted: for data that does not involve transactions and consensus (such as application resource demand data), only the data storage address can be stored on the chain.

In this embodiment, a blockchain network is constructed based on multiple operating platforms, and an edge intercommunication service execution system is generated. When a terminal initiates an edge intercommunication service request, the first operating platform to which the network it accesses belongs receives the service request at the first time. The first operating platform matches the accessible network, edge cloud resources, and application deployment requirements (resources, network requirements, whether deployed) and service indicators (including performance, cost, service response time, etc.) of the terminal at its location by querying the data on the blockchain based on the deployed smart contract, and decides on the optimal service solution (including access strategy, network solution, and cloud service selection, etc.), further triggering related operating platforms to implement network configuration and resource occupation, image push, and application instantiation operations, which are recorded on the blockchain in the form of a transaction after sharing and confirmation. The terminal's network access policy and edge application endpoint information are returned to the terminal through a response message, so that the terminal uses the edge service according to the access strategy.

The following describes the specific processing process of the edge intercommunication service execution system based on the edge intercommunication service execution method executed on the first operation platform side, the second operation platform side and the terminal side respectively.

FIG3 is a schematic diagram showing a method for executing edge intercommunication services in an embodiment of the present disclosure.

As shown in Figure 3, according to an edge intercommunication business execution method of an embodiment of the present disclosure, it is applied to a first operation platform, the first operation platform is used to manage network resources, the first operation platform and at least one second operation platform are configured as blockchain nodes in a blockchain network, and the first operation platform and the second operation platform store and install smart contracts.

Specifically, the edge intercommunication service execution method includes:

Step S302, in response to the business request of the edge application sent by the terminal, query the application requirements matching the business request on the blockchain based on the deployed smart contract, so as to determine the second operating platform for processing the business request based on the application requirements.

The business request of the edge application is used to request the edge service executed based on the edge node.

Based on the deployed smart contract, the application requirements that match the business request are queried on the blockchain, specifically including: determining the application information corresponding to the business request, querying the application configuration requirements published by the third operating platform based on the application information, including cloud resource requirements and network requirements, determining the matching second operating platform based on the cloud resource requirements, obtaining the corresponding edge application from the second operating platform, and further establishing a network connection between the terminal and the edge application.

Step S304: Initiate a business transaction on the blockchain so that the second operating platform can obtain edge applications that meet application requirements on the matching edge cloud based on the smart contract.

Among them, the second operation platform obtains edge applications that meet application requirements on the matching edge cloud based on the smart contract, including but not limited to the following implementation methods:

If an edge application that meets the business request has been deployed, directly select the edge application. If the deployed edge application cannot meet the application requirements, adjust the edge application to obtain an edge application that meets the business request. If an edge application that meets the business request has not been deployed, directly perform the deployment operation.

Step S306: Generate a network access policy for the terminal to access the edge application based on the smart contract, and perform network configuration based on the network access policy.

Among them, generating a network access policy for network terminals to access edge applications and performing network configuration based on the network access policy can be achieved by configuring a customized network.

Step S308: Send the network access policy to the terminal, so that the terminal establishes a network connection with the edge cloud based on the network access policy, so that the terminal accesses the edge application.

Among them, based on the acquired edge application, it is necessary to further configure the network access policy for the terminal to access the edge application so that the terminal can access the edge application.

In this embodiment, in a blockchain network including a first operating platform and a second operating platform, when the first operating platform receives a business request of an edge application sent by a terminal, the first operating platform performs a query operation of a matching business plan on the blockchain based on a smart contract to find out matching application deployment requirements and cloud resources, and based on the matching result, determines a second operating platform that has deployed or can deploy the edge application, so that the second operating platform can provide edge application services, and further generates a network access policy for accessing the edge application based on its own network resources, and sends the network access policy to the terminal, so that the terminal establishes a network connection with the edge cloud where the edge terminal is located, so that a better service plan that meets the business request can be configured based on the resources shared on the blockchain. On the one hand, it is conducive to improving the user's access experience to the edge application, and on the other hand, it can also ensure the fairness of the service plan determined by the cooperation of multiple operating platforms, and prevent the phenomenon that some resource providers provide non-optimized service plans based on their own interests.

In one embodiment of the present disclosure, in response to a service request of an edge application sent by a terminal, querying an application requirement matching the service request on a blockchain based on a deployed smart contract includes:

In response to business requests, the cloud resource requirements and network requirements of edge application deployment are queried on the blockchain based on smart contracts.

Identify cloud resource requirements and network requirements as application requirements.

In this embodiment, based on the available connections and network openness published by the network provider through the first operating platform on the blockchain, the service area, computing resources, fees, etc. of the resource pool published by the cloud service provider through the second operating platform on the blockchain, and the deployment requirements and business requirements (service area, performance indicators, continuity assurance requirements, service call requirements, etc.) of the application published by the application provider on the blockchain, the first operating platform can query the deployment requirements and business requirements of the application published by the application provider on the blockchain on the chain after obtaining the business request, and then determine the corresponding cloud resource requirements and network requirements based on the deployment requirements and business requirements of the application, so as to determine the matching and preferred application requirements.

As shown in FIG. 4 , in one embodiment of the present disclosure, in step S304, a business transaction is initiated on the blockchain, so that the second operation platform obtains an edge application that meets the application requirements on the matching edge cloud based on the smart contract. A specific implementation method includes:

Step S402: calling the location information of the terminal based on the network capability, or receiving the location information reported by the terminal.

Step S404, triggering the smart contract to determine the service area matching the location information.

Step S406, triggering the smart contract to query the blockchain for cloud resource requirements that match the business request and are within the service area, where the cloud resource requirements include computing resource requirements and storage resource requirements.

Step S408, triggering the smart contract to query the available edge cloud resources in the service area that match the business request on the blockchain, and selecting target cloud resources that match the cloud resource requirements and network requirements from the edge cloud resources to determine a matching edge cloud that can obtain the edge application.

In this embodiment, the location information of the terminal is obtained to determine the corresponding service area, and the cloud resource demand belonging to the service area is further determined, so that the available edge cloud resources in the service area can be queried based on the cloud resource demand to obtain the target cloud resources that match the cloud resource demand and the network demand, so as to ensure that the edge applications deployed based on the target cloud resources can be reliably accessed by the terminal.

In one embodiment of the present disclosure, a target cloud resource that matches the cloud resource requirements and the network requirements is selected from the edge cloud resources to determine a matching edge cloud that can acquire the edge application, and also includes: receiving the access IP of the edge application fed back by the second operating platform to send the access IP and the network access policy to the terminal.

As shown in FIG. 5 , in one embodiment of the present disclosure, in step S306, a specific implementation method of generating a network access policy for a terminal to access an edge application based on a smart contract includes:

Step S502, triggering the smart contract to query the blockchain for network requirements that match the business request, where the network requirements include at least one of network isolation requirements, network capabilities, and network service quality.

Step S504, triggering the smart contract to determine the network resources that match the network requirements.

Step S506 , triggering the network management platform to configure a customized network for accessing edge applications based on network resources and access IP.

Specifically, as a specific implementation method for configuring a customized network, it specifically includes: configuring network slices that can use network resources to access edge applications on a network management platform based on smart contracts as a customized network. Each network slice can provide complete network functions (including the functions of the access network (RAN) and the core network (CN)), thereby meeting the needs of network customization.

In addition, those skilled in the art can understand that any solution that can implement network customization based on specified resources falls within the protection scope of this solution.

Step S508: Generate a network access policy for the customized network.

In one embodiment of the present disclosure, in step S508, a specific implementation of generating a network access policy for a customized network includes:

Based on the identification of network resources and edge applications, the corresponding path descriptor TD and routing descriptor RSD are determined; based on TD and RSD, a terminal routing policy URSP is generated to serve as a network access policy for the terminal.

Specifically, a URSP (User Terminal Routing Selection Policy) rule is defined in the 3GPP 5G protocol. This rule is used to describe the correspondence between edge applications and customized networks. The terminal operating system needs to select a customized network for edge applications according to the URSP rule. There are two important groups of parameters in the URSP rule. One group is the Traffic Descriptor (path descriptor) parameters that describe the attributes of edge applications, including AppId, DNN (data network name), IP Descriptor (IP triplet), Domain Descriptor (domain name descriptor), Connection Capabilities and other parameters. The other group is the Route Selection Descriptor (route selection descriptor) that describes the data bearer attributes, including S-NSSAI (network slicing), SSC Mode (session and service continuity mode), DNN and other parameters. The URSP rule is actually the correspondence between multiple groups of Traffic Descriptors and Route Selection Descriptors. When the terminal knows the Traffic Descriptor parameters related to the edge application, it can naturally find the Route Selection Descriptor related to data carrying according to the URSP rules, which contains the customized network information to determine which customized network the edge application should access.

In this embodiment, by configuring a corresponding customized network for the edge application based on the first operating platform in the blockchain network, on the one hand, the fairness and reliability of the customized network configuration are guaranteed, and on the other hand, the traceability of the network configuration transaction is also guaranteed.

Specifically, as shown in FIG6 , the network requirements include:

Network isolation requirement: Medium.

Network capabilities: including traffic offloading and UE positioning.

QoS: Bandwidth: 100M, latency: 20ms, packet loss rate: 10^-2.

Cloud network connection: 1000M.

Based on the above network requirements, the smart contract is triggered to determine the network resources that match the network requirements, including:

Slice S-NSSAI-a. Guaranteed bandwidth: 100M. 5QI=79.

Cloud network dedicated line product 1: 1000M SRV6EVPN

In order to enable users to use services in a customized network, the smart contract also generates relevant user access policies, such as URSP (User Routing Selection Policy), as shown below:

TD (Traffic Descriptor): Application descriptor = federation example

RSD (Route Selection Descriptor): Network Slice Selection: S-NSSAI-a.

As shown in FIG7 , according to another embodiment of the present disclosure, a method for executing edge intercommunication services is applied to a first operation platform and specifically includes:

Step S702: Publishing network resources that can provide network connection on the blockchain.

Step S704, in response to the business request of the edge application sent by the terminal, query the application requirements matching the business request on the blockchain based on the deployed smart contract.

Step S706: Initiate a business transaction on the blockchain so that the second operating platform can obtain edge applications that meet the application requirements on the matching edge cloud based on the smart contract.

Step S708: Generate a network access policy for the terminal to access the edge application based on the smart contract, and perform network configuration based on the network access policy.

Step S710, in response to the generated network access policy, broadcast first transaction information of the edge intercommunication service executed by the first operating platform in the blockchain based on the smart contract to record the first transaction information in the blockchain.

Step S712: updating network resources that can provide network connection based on the first transaction information.

In this embodiment, after completing the matching and configuration transaction process based on the smart contract, the transaction is confirmed to further complete the update of resource data and the record of transactions on the blockchain. On the one hand, it ensures that the transaction records are traceable. On the other hand, based on the update of resource data, when a business request from a new edge application is obtained, the application configuration is performed based on the updated resource data.

As shown in FIG8 , according to another embodiment of the present disclosure, an edge intercommunication service execution method is applied to a second operation platform, and the second operation platform is used to manage cloud resources. The edge intercommunication service execution method includes:

Step S802, in response to a business transaction of the edge intercommunication service initiated by the first operating platform on the blockchain, an edge application that meets the application requirements of the edge intercommunication service is obtained on a matching edge cloud based on a deployed smart contract.

In this embodiment, in a blockchain network including a first operating platform and a second operating platform, when the first operating platform receives a business request for an edge application sent by a terminal, the first operating platform initiates a business transaction for an edge intercommunication business to the second operating platform. In response to the business transaction, the second operating platform provides the edge application services required for the business transaction, so as to configure a better service solution that meets the business request based on the resources shared on the blockchain. On the one hand, this is conducive to improving the user's access experience to the edge application. On the other hand, it can also ensure the fairness of the service solutions determined by the cooperation of multiple operating platforms, and prevent the occurrence of the phenomenon that some resource providers provide non-optimized service solutions based on their own interests.

As shown in FIG. 9 , in one embodiment of the present disclosure, in step S802, a specific implementation method of obtaining an edge application that meets the application requirements of the edge intercommunication service on a matching edge cloud based on a deployed smart contract includes:

Step S902: Detecting a plurality of selectable edge clouds.

Select a matching edge cloud from multiple selectable edge clouds based on preset priority selection conditions to obtain edge applications, including:

Step S904: A first edge cloud having a deployed edge application is detected among a plurality of selectable edge clouds.

Step S906: If there is only one first edge cloud, directly determine the first edge cloud as the matching edge cloud.

Step S908: If there are multiple first edge clouds, a target edge cloud is selected from the multiple first edge clouds based on a preset selection rule and determined as a matching edge cloud.

The preset selection rules include but are not limited to at least one of a quality priority rule, a cost priority rule and a deployment difficulty priority rule.

Further, determining the first edge cloud as a matching edge cloud specifically includes:

Step S910, detect whether the edge application on the first edge cloud meets the business transaction, if "yes", go to step S908, if "no", go to step S910.

Step SS912, directly obtain edge application.

Step SS914, adjust the edge application to satisfy the business transaction to obtain the adjusted edge application.

Among them, adjusting edge applications includes but is not limited to adjusting storage space, adjusting the number of CPU cores, adjusting the number of CPU cores, and adjusting the application deployment method.

Step SS916, detects that the first edge cloud is not included in multiple selectable edge clouds, determines the second edge cloud with the most idle resources in the multiple selectable edge clouds, determines the second edge cloud as a matching edge cloud, and deploys edge applications on the second edge cloud based on the smart contract.

In this embodiment, if there are multiple selectable edge clouds, a matching edge cloud is selected from these edge clouds based on the set priority conditions. Specifically, if there is a first edge cloud on which the edge application has been deployed, the first edge cloud can be determined as a matching edge cloud. Further, it is detected whether the edge application satisfies the business transaction. If it does, the application can be directly acquired. If it does not, it can be acquired after adjustment. If there is no first edge cloud, a second edge cloud with the most idle resources is selected from multiple selectable edge clouds, and the edge application deployment operation is performed to further acquire the edge application, thereby ensuring that the acquired edge application is the preferred service solution.

As shown in FIG. 10 , in one embodiment of the present disclosure, in step S910, deploying edge applications on a matching edge cloud based on a smart contract includes:

Step S1002, in response to the business transaction, query the available edge cloud resources in the service area that can meet the business request on the blockchain based on the smart contract.

Step S1004, selecting a target cloud resource that matches the cloud resource requirements and the network requirements from the edge cloud resources to determine a matching edge cloud that can acquire the edge application.

Step S1006, deploying edge applications on the edge cloud based on smart contracts.

In this embodiment, the available edge cloud resources in the service area are queried based on the cloud resource requirements to obtain target cloud resources that match the cloud resource requirements and network requirements, so as to ensure that edge applications deployed based on the target cloud resources can be reliably accessed by the terminal.

As shown in Figure 11, the application requirements include: 1T storage space, 20 CPU cores, 10 GPU cores, and container deployment mode. Matching is performed based on pre-deployed business resources. The corresponding matching results include:

The specific products are cloud storage product 1 and cloud computing product 1.

Application integration includes network traffic diversion, positioning capabilities, and containerized deployment.

The access IP is 10.50.2.2.

Specifically, in step S1006, a specific implementation method of deploying edge applications on the edge cloud based on smart contracts includes: creating a service instantiation of the edge cloud on the cloud management platform using an image based on the smart contract to deploy the edge application.

In one embodiment of the present disclosure, selecting a target cloud resource that matches the cloud resource requirement and the network requirement from the edge cloud resources to determine a matching edge cloud capable of acquiring the edge application also includes:

Feedback the access IP address of the edge application to the first operation platform.

As shown in FIG. 12 , an edge intercommunication service execution method according to another embodiment of the present disclosure is applied to a second operation platform and specifically includes:

Step S1202, publish cloud resource pool information on the blockchain, the cloud resource pool information includes service area, computing resources and deployed application information.

Step S1204, in response to the business transaction of the edge intercommunication service initiated by the first operating platform on the blockchain, an edge application that meets the application requirements of the edge intercommunication service is obtained on the matching edge cloud based on the deployed smart contract.

Step S1206, in response to the deployment operation of the edge application, broadcast the second transaction information of the edge intercommunication service executed by the second operation platform in the blockchain based on the smart contract to record the second transaction information in the blockchain.

Step S1208: Update the cloud resource pool information based on the second transaction information.

In this embodiment, after completing the matching and configuration transaction process based on the smart contract, the transaction is confirmed to further complete the update of resource data and the record of transactions on the blockchain, thereby ensuring that the transaction records of the cloud resource pool information are traceable and broadcasting the cloud resources that can be provided after the update on the chain.

As shown in FIG13 , a method for executing an edge intercommunication service according to another embodiment of the present disclosure is applied to a terminal, including:

Step S1302: Send a business request for the edge application to the first operation platform, so that the first operation platform triggers the second operation platform in the blockchain to obtain the edge application on the edge cloud based on the business request.

Step S1304: receiving a network access policy of the edge application based on the service request feedback from the first operation platform, so as to establish a network connection for accessing the edge application based on the network access policy.

In this embodiment, the terminal sends a business request of the edge application to the first operating platform to which the accessed network belongs, and receives a network access policy for the edge application generated by the first operating platform based on the service resources provided in the blockchain network, so as to obtain a better service solution that meets the business request based on the resources shared on the blockchain. On the one hand, it is conducive to improving the user's access experience to the edge application. On the other hand, it can also ensure the fairness of the service solutions determined by the cooperation of multiple operating platforms, and prevent the occurrence of the phenomenon that some resource providers provide non-optimized service solutions based on their own interests.

In one embodiment of the present disclosure, in step S1304, an implementation method of establishing a network connection for accessing an edge application based on a network access policy includes:

A protocol data unit (PDU) session is established based on the network access policy.

Specifically, taking network slicing configuration and customized network as an example, the implementation method of establishing a protocol data unit PDU session based on the network access policy includes: establishing a protocol data unit PDU session with the network slice based on the network access policy, and the network slice is configured by the first operating platform on the network management platform.

Receive the access IP of the edge application sent by the first operation platform to access the edge application based on the access IP and PDU session.

As shown in FIG14 , according to an edge intercommunication service execution interaction method of another embodiment of the present disclosure, the interaction parties include a wireless access device AC, a terminal UE, a network provider, a first operation platform OP1, a blockchain storage device, a second operation platform OP2, and a cloud service provider or an application service provider, wherein the blockchain storage device is used to store the shared resources and information of the network provider, the edge cloud provider, and the application provider, and the interaction process specifically includes:

In step S1402, the network provider, edge cloud provider, and application provider publish their respective shared resources and information through their respective OPs, and communicate with the management and control channels between each OP and the corresponding resource entity.

Specifically, as a starting condition, the resource conditions of the network and cloud have been recorded on the blockchain, and each OP has reached an agreement on the terms of cooperation and deployed smart contracts.

Step S1404: The AC initiates an edge application service request to the UE.

Step S1406: UE initiates an edge application service request to OP1.

Specifically, if an application client on a UE wants to access a certain edge application, it first initiates a service discovery request.

In addition, the UE is attached to the designated network, so the request is sent to OP1 to which the network belongs.

Step S1408, OP1 obtains the terminal location information.

OP1 may obtain the location of the terminal by invoking the network location capability, or OP1 may obtain the location of the terminal by other means, such as obtaining the location of the terminal through reporting by the client.

Step S1410, reading blockchain data based on the smart contract to determine network resources and application products that match the current location and business request.

Specifically, the smart contract on OP1 reads the blockchain data, matches the resources and application requirements of the current location, and assumes that the matching result is the cloud service product on the edge cloud 2 of OP2, and then initiates a transaction on the blockchain to reach a consensus.

Step S1412, based on the smart contract, the image is captured, and the application product is instantiated and deployed on the cloud server or application server, and the business access policy is fed back.

Specifically, the smart contract triggers OP2 to grab the image and complete the service instantiation and application deployment on edge cloud 2 on the cloud management.

Step S1414, based on the smart contract trigger, the slice network is configured on the network management, and a network access policy for the UE to access the cloud server or application server is generated.

Specifically, the smart contract triggers OP1 to configure the slice network on the network management system and generate a network access policy for UE to access edge applications.

Step S1416: After the smart contract executes the management process, the transaction is confirmed, and the resource data is updated and the transaction is recorded on the blockchain.

Specifically, after the smart contract executes the management process, it confirms the transaction and completes the update of resource data and transaction recording on the blockchain.

Step S1418: Return the network access policy and service visitor policy to the UE.

Specifically, OP1 returns the network access policy and access endpoint to the UE via a response message.

Step S1420, establish a network slice session connection based on the network access policy.

Specifically, the UE establishes a network connection for accessing edge applications according to the network access policy, that is, establishes a session connection for a customized slice.

Step S1422, return the request result.

Specifically, the UE returns the application endpoint information returned by OP1 to the AC.

Step S1424, access edge application.

Specifically, the AC uses the endpoint information as the access target and accesses the application on the edge cloud through the session connection established by the UE.

In this embodiment, in order to introduce OP to build the security, trustworthiness, fairness and justice of the edge computing service ecosystem, the network provider publishes the connection and network openness capabilities it can provide on the blockchain through its affiliated OP, the cloud service provider publishes the service area, computing power resources, and fees of its resource pool on the blockchain through its affiliated OP, and the application provider publishes the deployment requirements and business requirements (service area, performance indicators, continuity guarantee requirements, service call requirements, etc.) of its application on the blockchain through its affiliated OP. All OPs form a consortium chain and run smart contracts. When the UE initiates an edge intercommunication service request, the affiliated OP of the network it accesses receives the information at the first time. The smart contract of the OP matches the accessible network, edge cloud resources, application deployment requirements (resources, network requirements, whether it has been deployed) and service indicators (including performance, cost, service response time, etc.) of the UE at its location by querying the data on the blockchain, and decides on the optimal service plan (including network access strategy, network plan and cloud service selection, etc.), further triggering the relevant OP to implement network configuration and resource occupation, image push and application instantiation and other operations, and record them on the blockchain in the form of transactions after sharing confirmation. The user network access policy and edge application endpoint information are returned to the UE through a response message, and the UE uses the edge service according to the network access policy.

The above solution prevents some operators or service providers from providing non-optimized service solutions based on their own interests, which affects user experience. At the same time, it ensures that the cooperative operation process is traceable and cannot be tampered with, enabling a fair and just cooperative operation environment.
