目前，欧洲电信标准化协会(European Telecommunications Standards Institute，ETSI)标准为MEC技术定义了标准架构，在MEC的标准架构程中，当部署一个新的MEC APP的时候，需要人工参与该MEC APP的上线，比如，需要人工配置该MEC APP的网络域与计算域之间的通信链路。因此，目前在MEC APP上线的过程中，需要人工参与，导致MEC APP上线效率低，对MEC App的运维成本比较高。At present, the European Telecommunications Standards Institute (ETSI) standard defines a standard architecture for MEC technology. In the standard architecture process of MEC, when deploying a new MEC APP, it is necessary to manually participate in the online launch of the MEC APP. For example, the communication link between the network domain and the computing domain of the MEC APP needs to be manually configured. Therefore, at present, in the process of launching MEC APP, manual participation is required, resulting in low efficiency of launching MEC APP and high operation and maintenance cost of MEC APP.

为了便于理解本申请，首先在此介绍本申请实施例涉及的相关技术知识。In order to facilitate the understanding of the present application, the related technical knowledge involved in the embodiments of the present application is first introduced here.

伴随5G技术成熟和普及，高带宽低时延应用业务在终端侧逐渐发展成熟，5G连接+边缘计算融合解决方案成为各大厂家纷纷追求的目标和愿景。欧洲电信标准化协会(European Telecommunications Standards Institute，ETSI)标准中定义的多接入边缘计算(Multi-access Edge Computing，MEC)解决方案，满足了信息提供方(Over The Top，OTT)在边缘侧对低时延、高吞吐业务的诉求。With the maturity and popularization of 5G technology, high-bandwidth and low-latency application services have gradually developed on the terminal side, and 5G connection + edge computing fusion solutions have become the goals and visions of major manufacturers. The Multi-access Edge Computing (MEC) solution defined in the European Telecommunications Standards Institute (ETSI) standard meets the requirements of the information provider (Over The Top, OTT) on the edge side to low Delay and high-throughput business demands.

ETSI标准定义了多接入边缘计算应用编排器(Multi-access Edge Computing Application Orchestrator，MEAO)和多接入边缘计算平台管理器(Multi-access Edge Computing Platform Manager，MEPM)两个部署于中心侧的管理部件，同时定义了应用程序描述(Application Description，APPD)信息，其中，APPD描述了即将部署的多接入边缘计算应用程序(Multi-access Edge ComputingApplication，MEC APP)的实例信息，比如，MEC APP的资源信息、依赖的多接入边缘计算MEC服务(Service)、提供的服务、分流规则(Traffic Rule)、优雅退出、MEC APP的标识，等等；然后，MEPM通过Mm5接口以配置请求(Configure Request)消息将APPD中的关键信息下发给边缘侧的MEP处理，MEP对Configure Request进行解析，与本地的数据平台(Date Plane)完成MEC APP的实例化部署。下面结合附图说明MEC APP的实例化部署过程。The ETSI standard defines the Multi-access Edge Computing Application Orchestrator (MEAO) and the Multi-access Edge Computing Platform Manager (MEPM) which are deployed on the center side. The management component also defines the application description (Application Description, APPD) information, where the APPD describes the instance information of the multi-access edge computing application (Multi-access Edge Computing Application, MEC APP) to be deployed, for example, MEC APP resource information, dependent multi-access edge computing MEC services (Service), provided services, traffic rules (Traffic Rule), graceful exit, MEC APP identification, etc.; then, MEPM uses the Mm5 interface to configure the request (Configure Request) message sends the key information in the APPD to the MEP on the edge side for processing, the MEP parses the Configure Request, and completes the instantiation and deployment of the MEC APP with the local data platform (Date Plane). The instantiation deployment process of the MEC APP is described below in conjunction with the accompanying drawings.

如图1所示，操作支持***(Operations Support Systems，Oss)向MEAO发送应用程序实例化请求(Instantiate application request)消息，MEAO将Instantiate application request消息转发给MEPM；然后，MEPM向网络功能虚拟化基础设施(Network Functions Virtualization Infrastructure，NFVI)发送资源分配请求(resource allocation request)消息；NFVI完成资源分配后，向MEPM返回资源分配响应(resource allocation response)消息，该resource allocation request携带分配好的资源信息；MEPM向MEP发送Configure Request消息，该Configure Request消息携带MEC APP的关键信息以及分配好的资源；MEP基于该Configure Request消息配置该MEC APP，即对MEC APP进行实例化；最后，实例化完成之后，MEP向MEAO返回应用程序实例化响应(Instantiate application response)消息，并将Instantiate application response消息转发给Oss。As shown in Figure 1, the operations support system (Operations Support Systems, Oss) sends an application instantiation request (Instantiate application request) message to MEAO, and MEAO forwards the Instantiate application request message to MEPM; then, MEPM sends a message to the network function virtualization foundation The facility (Network Functions Virtualization Infrastructure, NFVI) sends a resource allocation request (resource allocation request) message; after the NFVI completes the resource allocation, it returns a resource allocation response (resource allocation response) message to the MEPM, and the resource allocation request carries the allocated resource information; The MEPM sends a Configure Request message to the MEP, and the Configure Request message carries the key information of the MEC APP and allocated resources; the MEP configures the MEC APP based on the Configure Request message, that is, instantiates the MEC APP; finally, after the instantiation is completed, MEP returns an application instantiation response (Instantiate application response) message to MEAO, and forwards the Instantiate application response message to Oss.

虽然，APPD描述了MEC APP的实例信息，但是描述字段有限，有些信息没有描述，对于未描述的信息则需要人工重新配置。比如，ETSI MEC标准定义的MEP为MEC APP提供了MP1接口集(MEP functional MP1接口)，该MP1接口集包括多种功能的MP1接口，这些MP1接口包括用于服务发布的MP1接口，用于服务发现的MP1接口，用于接收订阅的MP1接口，等等。然而，并不是所有的MEC APP都支持该MP1接口集中的所有MP1接口，也就是说有些应用提供方会根据自己的需求为MEC APP开发相应的MP1接口，为了MEP与MEC APP在MP1接口集上的成功对接，则在MEC APP上线时，人工将MEC APP所支持的MP1接口，通过APPD描述文件传递给MEPM，并通过MEPM下发给MEP。Although APPD describes the instance information of MEC APP, the description fields are limited, some information is not described, and manual reconfiguration is required for undescribed information. For example, the MEP defined by the ETSI MEC standard provides an MP1 interface set (MEP functional MP1 interface) for the MEC APP. The MP1 interface set includes MP1 interfaces with multiple functions, and these MP1 interfaces include MP1 interfaces for service publishing. MP1 interface for discovery, MP1 interface for receiving subscriptions, etc. However, not all MEC APPs support all MP1 interfaces in the MP1 interface set, that is to say, some application providers will develop corresponding MP1 interfaces for MEC APP according to their own needs, for MEP and MEC APP on the MP1 interface set If the connection is successful, when the MEC APP goes online, manually transfer the MP1 interface supported by the MEC APP to the MEPM through the APPD description file, and deliver it to the MEP through the MEPM.

此外，在完成对MEC APP的实例化之后，为了本地分流则需要打通MEC APP的通信链路，即MEC APP、MEC服务实例以及用户面功能实体(User Plane Function，UPF)之间的通信链路。目前，都是在人工查看到MEC APP的实例化完成(Ready)之后，人工配置MEC APP与MEC Service实例之间的通信链路，以及人工配置MEC Service实例与UPF之间的通信链路。In addition, after the instantiation of the MEC APP is completed, the communication link of the MEC APP needs to be opened for local offloading, that is, the communication link between the MEC APP, the MEC service instance and the User Plane Function (UPF). . At present, after manually viewing the instantiation of the MEC APP (Ready), manually configure the communication link between the MEC APP and the MEC Service instance, and manually configure the communication link between the MEC Service instance and the UPF.

可以看出，目前在MEC APP上线的过程中，需要人工参与，导致MEC APP上线效率低，对MEC APP的运维成本比较高。It can be seen that at present, in the process of launching MEC APP, manual participation is required, resulting in low MEC APP launch efficiency and relatively high operation and maintenance costs for MEC APP.

参阅图2，图2为本申请实施例提供的一种业务路径建立的***架构图。该***架构包括多接入边缘计算平台10和多接入边缘计算应用程序20。其中，多接入边缘计算平台10中部署有一个或多个接入边缘计算服务实例，多接入边缘计算应用程序20中部署有一个或多个服务实例，其中，多接入边缘计算服务实例用于为该多接入边缘计算应用程序20中的服务实例提供多接入边缘计算服务，每个服务实例用于为用户提供边缘内容。Referring to FIG. 2 , FIG. 2 is a system architecture diagram for establishing a service path according to an embodiment of the present application. The system architecture includes a multi-access edge computing platform 10 and a multi-access edge computing application 20 . Among them, one or more access edge computing service instances are deployed in the multi-access edge computing platform 10, and one or more service instances are deployed in the multi-access edge computing application program 20, wherein the multi-access edge computing service instances are It is used to provide multi-access edge computing services for service instances in the multi-access edge computing application 20, and each service instance is used to provide users with edge content.

示例性的，多接入边缘计算应用程序20向多接入边缘计算平台10发送第一请求消息，其中，该第一请求消息用于从多接入边缘计算平台10获取多接入边缘计算服务实例与多接入计算应用程序之间的业务路径；多接入边缘计算平台10配置多接入边缘计算服务实例与多接入边缘计算应用程序20之间的业务路径，并将该业务路径下发给多接入边缘计算应用程序20，相应的，多接入边缘计算应用程序20根据该业务路径，建立与多接入边缘计算服务实例之间的业务路径，即打通了多接入边缘计算应用程序20和多接入边缘计算服务实例之间的业务链路。Exemplarily, the multi-access edge computing application 20 sends a first request message to the multi-access edge computing platform 10, where the first request message is used to obtain the multi-access edge computing service from the multi-access edge computing platform 10. The service path between the instance and the multi-access computing application; the multi-access edge computing platform 10 configures the service path between the multi-access edge computing service instance and the multi-access edge computing application 20, and assigns the service path to the service path. It is sent to the multi-access edge computing application 20. Correspondingly, the multi-access edge computing application 20 establishes a business path with the multi-access edge computing service instance according to the service path, that is, the multi-access edge computing is opened. A business link between an application 20 and a multi-access edge computing service instance.

可以看出，在本申请实施例中，多接入边缘计算平台可以根据第一请求消息自动配置多接入边缘计算应用程序与多接入边缘计算服务实例之间的业务路径，无需人工配置，进而降低多接入边缘计算应用程序的运维成本。It can be seen that in the embodiment of the present application, the multi-access edge computing platform can automatically configure the service path between the multi-access edge computing application and the multi-access edge computing service instance according to the first request message, without manual configuration, This in turn reduces the operation and maintenance cost of multi-access edge computing applications.

应理解，该***架构中还包括多接入边缘计算编排器(Multi-access Edge Orchestrator，EMAO)、多接入边缘计算平台管理器(Multi-access Edge Manager，MEPM)，等等。这些设备用于执行其他的业务过程，比如，在建立业务路径之前，MEAO、网络功能虚拟化编排器(Network Functions VirtualizationOrchestrator，NFVO)与其他设备之间协调工作，完成多接入边缘计算应用程序的部署以及实例化，本申请不去描述多接入边缘计算应用程序的部署过程。It should be understood that the system architecture also includes a multi-access edge computing orchestrator (Multi-access Edge Orchestrator, EMAO), a multi-access edge computing platform manager (Multi-access Edge Manager, MEPM), and the like. These devices are used to perform other business processes. For example, before establishing a business path, MEAO, Network Functions Virtualization Orchestrator (NFVO) and other devices coordinate work to complete multi-access edge computing applications. Deployment and instantiation, this application does not describe the deployment process of multi-access edge computing applications.

参阅图3，图3为本申请实施例提供的一种业务路径建立方法的流程示意图。该方法包括以下步骤：Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a method for establishing a service path according to an embodiment of the present application. The method includes the following steps:

301：多接入边缘计算应用程序向多接入边缘计算平台发送第一请求消息。301: The multi-access edge computing application sends a first request message to the multi-access edge computing platform.

其中，第一请求消息用于从多接入边缘计算平台获取多接入边缘计算服务实例与多接入边缘计算应用程序之间的业务路径，多接入边缘计算服务实例用于提供多接入边缘计算服务。示例性的，该业务路径包括业务规则和/或通信链路。The first request message is used to obtain the service path between the multi-access edge computing service instance and the multi-access edge computing application program from the multi-access edge computing platform, and the multi-access edge computing service instance is used to provide multi-access edge computing services. Edge computing services. Exemplarily, the service path includes service rules and/or communication links.

具体的，业务规则用于表征该多接入边缘计算服务实例与该多接入边缘计算应用程序中的服务实例之间的对应关系，该多接入边缘计算服务实例用于给该多接入边缘计算应用程序提供该多接入边缘计算服务，该多接入边缘计算应用程序中的服务实例用于给用户提供边缘数据。比如，该多接入边缘计算服务实例用于提供负载均衡(Load Balance，LB)服务(Service)，并且该多接入边缘计算服务实例的数量是2个，而且，这两个多接入边缘计算服务实例为该多接入边缘计算应用程序的10个服务实例提供LB Service；然后，建立这2个多接入边缘计算服务实例与该10个服务实例之间的映射关系，比如，第一个多接入边缘计算服务实例为该10个服务实例中的前五个服务实例提供LB Service，第二个多接入边缘计算服务实例为该10个服务实例中的后五个服务实例提供LB Service，即建立了多接入边缘计算服务实例与该多接入边缘计算应用程序之间的业务规则。Specifically, the business rule is used to characterize the correspondence between the multi-access edge computing service instance and the service instance in the multi-access edge computing application program, and the multi-access edge computing service instance is used to provide the multi-access edge computing service instance to the multi-access edge computing service instance. The edge computing application program provides the multi-access edge computing service, and the service instances in the multi-access edge computing application program are used to provide edge data to users. For example, the multi-access edge computing service instance is used to provide a load balancing (Load Balance, LB) service (Service), and the number of the multi-access edge computing service instance is 2, and the two multi-access edge computing service instances are The computing service instance provides LB Service for 10 service instances of the multi-access edge computing application; then, establish the mapping relationship between the two multi-access edge computing service instances and the 10 service instances, for example, the first The first multi-access edge computing service instance provides LB service for the first five service instances among the 10 service instances, and the second multi-access edge computing service instance provides LB service for the last five service instances among the 10 service instances. Service, that is, establishes business rules between the multi-access edge computing service instance and the multi-access edge computing application.

具体的，该路由参数用于表示该多接入边缘计算服务实例与多接入边缘计算应用程序之间的通信链路。示例性的，该路由参数可以为该多接入边缘计算服务实例的下行路由参数，则MEC APP可以基于该下行路由参数以及本端的上行路由参数，建立与该MEC服务实例之间的通信链路，然后，在上行传输的过程中，将本端的上行路由参数作为源地址，将多接入边缘计算服务实例的下行路由参数作为目标地址，建立通信链路，并传输数据报文。其中，MEC APP本端的上行路由参数可以由MEC APP的控制面为该MEC APP分配，并由该MEC APP注册给该MEP，然后，由该MEP转发给该多接入边缘计算服务实例，不再详细叙述。Specifically, the routing parameter is used to represent the communication link between the multi-access edge computing service instance and the multi-access edge computing application. Exemplarily, the routing parameter can be the downlink routing parameter of the multi-access edge computing service instance, then the MEC APP can establish a communication link with the MEC service instance based on the downlink routing parameter and the uplink routing parameter of the local end. , and then, in the process of uplink transmission, the uplink routing parameter of the local end is used as the source address, and the downlink routing parameter of the multi-access edge computing service instance is used as the destination address to establish a communication link and transmit data packets. Among them, the upstream routing parameters of the local end of the MEC APP can be allocated by the control plane of the MEC APP for the MEC APP, and registered with the MEP by the MEC APP, and then forwarded by the MEP to the multi-access edge computing service instance, no longer Describe in detail.

进一步地，通信链路还包括MEC APP与多接入边缘计算服务实例之间的VPN链路、网络切片实例、带宽、接口，等等。即MEC APP与MEC服务实例之间可使用的计算资源以及存储资源，使用哪条VPN链路，以及哪个接口(比如，N6接口)进行数据传输。Further, the communication link also includes the VPN link, network slice instance, bandwidth, interface, etc. between the MEC APP and the multi-access edge computing service instance. That is, the computing resources and storage resources that can be used between the MEC APP and the MEC service instance, which VPN link to use, and which interface (for example, the N6 interface) is used for data transmission.

示例性的，MEC APP可以通过MP1接口集中的第一MP1接口向该MEP发送该第一请求消息，其中，该第一MP1接口为多接入边缘计算平台的MP1接口集中提供多接入边缘服务订阅功能的MP1接口。也就是说，该第一请求消息是一条订阅消息，多接入边缘计算应用程序向多接入边缘计算平台订阅该多接入边缘计算服务。相应的，多接入边缘计算平台通过第一MP1接口向该多接入边缘计算应用程序发送该业务路径。Exemplarily, the MEC APP may send the first request message to the MEP through the first MP1 interface in the MP1 interface set, where the first MP1 interface is the MP1 interface set of the multi-access edge computing platform that provides multi-access edge services. MP1 interface for subscription function. That is, the first request message is a subscription message, and the multi-access edge computing application subscribes to the multi-access edge computing service from the multi-access edge computing platform. Correspondingly, the multi-access edge computing platform sends the service path to the multi-access edge computing application through the first MP1 interface.

应理解，若MEP中已部署了用于提供该多接入边缘计算服务的多接入边缘计算服务实例，并且该多接入边缘计算服务实例有足够的资源给该MEC APP提供该多接入边缘计算服务。比如，该多接入边缘计算服务实例的数量是2个，目前只给一个MEC APP中的5个服务实例提供多接入边缘计算服务，并且每个多接入边缘计算服务实例最多可以为MEC APP中的5个服务实例提供服务，因此，确定出该多接入边缘计算服务实例有剩余的资源给该MEC APP提供服务，则不用去部署该多接入边缘计算服务实例，只需要配置相应的业务规则以及通信链路即可。当然，若确定出该多接入边缘计算服务实例没有剩余资源或者未部署该多接入边缘计算服务实例，则需要先部署该多接入边缘计算服务实例。但是，这个多接入边缘计算服务实例不一定是由该MEC APP申请的，该MEC APP只是订阅了这个多接入边缘计算服务，也就是说，在没有相应的MEC服务实例的情况下，MEP可能不会立马去部署一个相应的MEC服务实例，而是等待该MEC服务实例上线。比如，后续其他MEC APP申请部署了这个MEC服务实例，MEP可以配置该MEC APP与该MEC服务实例之间的业务路径。It should be understood that if a multi-access edge computing service instance for providing the multi-access edge computing service has been deployed in the MEP, and the multi-access edge computing service instance has sufficient resources to provide the MEC APP with the multi-access Edge computing services. For example, the number of multi-access edge computing service instances is 2. Currently, only 5 service instances in one MEC APP are provided with multi-access edge computing services, and each multi-access edge computing service instance can be up to MEC The 5 service instances in the APP provide services. Therefore, it is determined that the multi-access edge computing service instance has remaining resources to provide services for the MEC APP, so there is no need to deploy the multi-access edge computing service instance, and only the corresponding The business rules and communication links are sufficient. Of course, if it is determined that the multi-access edge computing service instance has no remaining resources or the multi-access edge computing service instance is not deployed, the multi-access edge computing service instance needs to be deployed first. However, this multi-access edge computing service instance is not necessarily applied for by the MEC APP. The MEC APP just subscribes to this multi-access edge computing service. That is to say, in the absence of a corresponding MEC service instance, the MEP It may not immediately deploy a corresponding MEC service instance, but wait for the MEC service instance to go online. For example, when other MEC APPs apply to deploy this MEC service instance, the MEP can configure the business path between the MEC APP and the MEC service instance.

示例性的，MEC APP还可以通过新增的第一接口向该MEP发送该第一请求消息，该新增的第一接口用于提供多接入边缘计算服务申请的功能。也就是说，MEC APP通过该新增的第一接口发送第一请求消息，向MEP动态申请多接入边缘计算服务。Exemplarily, the MEC APP may also send the first request message to the MEP through a newly added first interface, where the newly added first interface is used to provide a function of applying for a multi-access edge computing service. That is to say, the MEC APP sends a first request message through the newly added first interface to dynamically apply for the multi-access edge computing service to the MEP.

应理解，在多接入边缘计算应用程序接收第一请求消息之前，则MEP需要扩增用于接收MEC服务申请消息的第一接口，以及发送MEC服务申请响应消息的第二接口，并将该新增的第一接口和新增的第二接口开放给MEC APP。因此，MEP在通过该新增的第一接口接收到该第一请求消息之后，解析该第一请求消息可得到该多接入边缘计算服务；然后，MEP根据该新增的第一接口的功能，确定该MEC APP申请部署该多接入边缘计算服务。相应的，MEP通过该新增的第二接口向该MEC APP发送该业务路径。It should be understood that before the multi-access edge computing application receives the first request message, the MEP needs to expand the first interface for receiving the MEC service application message, and the second interface for sending the MEC service application response message, and use the The newly added first interface and the newly added second interface are open to the MEC APP. Therefore, after receiving the first request message through the newly added first interface, the MEP can obtain the multi-access edge computing service by parsing the first request message; then, the MEP can obtain the multi-access edge computing service according to the function of the newly added first interface. , determine that the MEC APP applies for deploying the multi-access edge computing service. Correspondingly, the MEP sends the service path to the MEC APP through the newly added second interface.

应理解，若MEP中已部署了用于提供该多接入边缘计算服务的多接入边缘计算服务实例，并且该多接入边缘计算服务实例有足够的资源给该MEC APP提供该多接入边缘计算服务，则不用部署该多接入边缘计算服务实例，只需配置相应的业务规则以及路由参数。若确定出该多接入边缘计算服务实例没有剩余资源或者未部署该多接入边缘计算服务实例，则需要立即部署该多接入边缘计算服务实例，并在部署完成之后，配置该多接入边缘计算服务实例与该MEC APP之间的业务路径。It should be understood that if a multi-access edge computing service instance for providing the multi-access edge computing service has been deployed in the MEP, and the multi-access edge computing service instance has sufficient resources to provide the MEC APP with the multi-access For edge computing services, you do not need to deploy the multi-access edge computing service instance, but only need to configure corresponding business rules and routing parameters. If it is determined that the multi-access edge computing service instance has no remaining resources or the multi-access edge computing service instance is not deployed, the multi-access edge computing service instance needs to be deployed immediately, and after the deployment is completed, the multi-access edge computing service instance is configured The business path between the edge computing service instance and the MEC APP.

示例性的，MEC APP还可以通过MP1接口集中的任意一个MP1接口发送该第一请求消息，该第一请求消息是与该MP1接口格式匹配的消息，但在该第一请求消息中增加了新的字段，并在MEP和MEC APP中均增加对该字段的定义。这样MEP在接收到该第一请求消息后，除了解析该第一请求消息本身的功能之外，还可解析出该字段的功能。比如，在一个注册消息中新增了MEC服务申请的字段，并在该字段中携带该多接入边缘计算服务，则MEP解析该字段，除了获得该MEC APP的拓扑信息之外，还可以解析出该MEC APP申请部署该MEC服务。Exemplarily, the MEC APP can also send the first request message through any MP1 interface in the MP1 interface set, where the first request message is a message matching the format of the MP1 interface, but a new message is added in the first request message. field, and the definition of this field is added in both MEP and MEC APP. In this way, after receiving the first request message, the MEP can parse out the function of this field in addition to the function of parsing the first request message itself. For example, if a field of MEC service application is added in a registration message, and the multi-access edge computing service is carried in this field, the MEP parses this field. In addition to obtaining the topology information of the MEC APP, it can also parse the field. Apply to deploy the MEC service from the MEC APP.

302：多接入边缘计算平台配置多接入边缘计算服务实例与多接入边缘计算应用程序之间的业务路径，并向多接入边缘计算应用程序下发业务路径。相应的，多接入边缘计算应用程序建立与多接入边缘计算服务实例之间的业务路径。302: The multi-access edge computing platform configures a service path between the multi-access edge computing service instance and the multi-access edge computing application, and delivers the service path to the multi-access edge computing application. Correspondingly, the multi-access edge computing application program establishes a service path between the multi-access edge computing service instance.

应理解，多接入边缘计算平台同时将该业务路径发送给该多接入边缘计算服务实例。相应的，该多接入边缘计算服务实例建立与该多接入边缘计算应用程序之间的业务路径。It should be understood that the multi-access edge computing platform simultaneously sends the service path to the multi-access edge computing service instance. Correspondingly, the multi-access edge computing service instance establishes a service path with the multi-access edge computing application.

可以看出，在本申请实施例中，多接入边缘计算平台可自动生成多接入边缘计算服务实例与多接入边缘计算应用程序之间的业务路径，而不需要人工配置，降低了对多接入边缘计算应用程序的运维成本。It can be seen that, in the embodiment of the present application, the multi-access edge computing platform can automatically generate the service path between the multi-access edge computing service instance and the multi-access edge computing application program without manual configuration, which reduces the need for manual configuration. Operational and maintenance costs of multi-access edge computing applications.

示例性的，MEP配置该多接入边缘计算服务实例与多接入边缘计算应用程序之间的业务规则以及路由参数。示例性的，MEP可按照预先注入的业务策略模板配置该业务规则，比如，每个LB服务实例，服务MEC APP中的5个服务实例，并且按照从前往后的顺序依次进行配置；也可以按照预设算法进行配置，等等，本申请对配置方式不进行限定。Exemplarily, the MEP configures business rules and routing parameters between the multi-access edge computing service instance and the multi-access edge computing application. Exemplarily, the MEP can configure the business rule according to the pre-injected business policy template, for example, each LB service instance serves 5 service instances in the MEC APP, and configures it in order from front to back; The configuration is performed by a preset algorithm, etc., and the configuration method is not limited in this application.

应理解，由于该业务规则实质上是该多接入边缘计算服务实例与该多接入边缘计算应用程序中的服务实例之间的对应关系。因此，多接入边缘计算应用程序可以针对性的向多接入边缘计算应用程序中的服务实例发送该业务规则，即将每个多接入边缘计算应用程序中的服务实例可使用的多接入边缘计算服务的标识发送给该多接入边缘计算应用程序。示例性的， LB服务实例包括LB Service1和LB Service2，且该LB Service1为该MEC APP中的服务实例1～服务实例5提供边缘计算服务，LB Service2为该MEC APP中的服务实例6～服务实例10提供边缘计算服务，则可以将该LB Service1的标识(比如，虚拟IP地址)发送给服务实例1～服务实例5，并指示该服务实例1～服务实例5使用该LB Service1进行负载均衡。It should be understood that, because the business rule is essentially a correspondence between the multi-access edge computing service instance and the service instance in the multi-access edge computing application program.

表1：Table 1:

应理解，表1示出的指示MEC APP的网络参数的方式仅为举例说明，仅是说明可以通过在APPD通过新增字段的方式来指示MEC APP的网络参数，具体的指示可以多种多样的，比如，可以通过一个字段指示多个网络参数，等等。本申请不对指示方式进行限定。It should be understood that the method of indicating the network parameters of the MEC APP shown in Table 1 is only for illustration, and it is only to illustrate that the network parameters of the MEC APP can be indicated by adding a new field in the APPD, and the specific instructions can be various. , for example, multiple network parameters can be indicated by one field, and so on.

示例性的，MEP根据多接入边缘计算应用程序的网络参数，为该多接入边缘计算应用程序分配可使用的网络资源；然后，根据该多接入边缘计算应用程序可使用的网络资源配置该多接入边缘计算应用程序与该多接入边缘计算服务实例之间的通信链路。Exemplarily, the MEP allocates available network resources for the multi-access edge computing application according to the network parameters of the multi-access edge computing application; and then configures the network resources available for the multi-access edge computing application according to the A communication link between the multi-access edge computing application and the multi-access edge computing service instance.

示例性的，该通信链路包括但不限于下行路由参数、网络切片实例、带宽、虚拟专用网络(Virtual Private Network，VPN)链路、通信接口。比如，MEP可以根据MEC APP所属的网络切片进行网络切片实例映射，确定MEC APP可使用的网络切片实例；根据该MEC APP所属的签约用户组以及所属的虚拟局域网，配置MEC APP的VPN链路；根据MEC APP所属的签约用户组为该MEC APP分配相应的带宽以及通信接口，等等。Exemplarily, the communication link includes but is not limited to downlink routing parameters, network slice instances, bandwidth, virtual private network (Virtual Private Network, VPN) links, and communication interfaces. For example, the MEP can map network slice instances according to the network slice to which the MEC APP belongs, and determine the network slice instances that the MEC APP can use; configure the VPN link of the MEC APP according to the subscription user group to which the MEC APP belongs and the virtual local area network to which it belongs; The corresponding bandwidth and communication interface are allocated to the MEC APP according to the subscriber group to which the MEC APP belongs, and so on.

此外，MEP还可以根据该MEC APP的网络参数为MEC APP进行网络隔离以及权限管控。比如，MEP根据MEC APP所属的网络切片将MEC APP的行为隔离在该网络切片所对应的网络区域，也就是将该MEC APP所能订阅的MEC Service或者注册的服务实例隔离在这个网络区域，比如，该MEC APP所属的网络切片是提供2B业务，MEC APP所注册的服务实例，只能是用来提供2B服务，对于非法注册的服务实例则予以无效，也就是管理该MEC APP不能提供这类服务；此外，根据MEC APP所属的签约用户组对该MEC APP进行权限管理，比如，该MEC APP所属的签约用户组为已授权了位置信息访问权限或者带宽管理权限的签约用户组，则MEC APP可以进行位置访问和带宽管理。In addition, the MEP can also perform network isolation and permission control for the MEC APP according to the network parameters of the MEC APP. For example, the MEP isolates the behavior of the MEC APP in the network area corresponding to the network slice according to the network slice to which the MEC APP belongs. , the network slice to which the MEC APP belongs is to provide 2B services. The service instances registered by the MEC APP can only be used to provide 2B services, and the illegally registered service instances are invalid, that is, the management of the MEC APP cannot provide such services. In addition, the MEC APP is subject to authority management according to the contracted user group to which the MEC APP belongs. For example, if the contracted user group to which the MEC APP belongs is a contracted user group that has authorized location information access rights or bandwidth management rights, then the MEC APP Location access and bandwidth management are possible.

示例性的，多接入边缘计算平台根据多接入边缘计算应用程序的接口能力，与该MEC APP所支持的MP1接口进行对接，对该MEC APP所支持的MP1接口，自动化接收该MEC APP的交互消息，比如，可以将MEC APP所支持的MP1接口导入到MP1接***互以及自动化使能状态机中，这样可以通过该MP1接***互以及自动化使能状态机完成与该MEC APP的自动对接。比如，MEC APP支持上述第一MP1接口，则MEP可以对该第一MP1接口使能，自动化接收MEC APP的订阅消息，对于该MEC APP不支持的MP1接口，则不对这类MP1接口使能，也就不向该MEC APP开放这类的MP1接口。Exemplarily, the multi-access edge computing platform connects with the MP1 interface supported by the MEC APP according to the interface capability of the multi-access edge computing application, and automatically receives the MEC APP's MP1 interface supported by the MEC APP. For interactive messages, for example, the MP1 interface supported by the MEC APP can be imported into the MP1 interface interaction and automation enabling state machine, so that the automatic docking with the MEC APP can be completed through the MP1 interface interaction and the automation enabling state machine. For example, if the MEC APP supports the above-mentioned first MP1 interface, the MEP can enable the first MP1 interface to automatically receive subscription messages from the MEC APP. This kind of MP1 interface is not open to the MEC APP.

可以看出，通过在APPD中描述MEC APP的接口能力，可以使MEP仅与MEC APP所支持的MP1接口完成对接，有针对性的开放部分MP1接口，提高MEP与MEC APP对接的灵活性。It can be seen that by describing the interface capability of the MEC APP in APPD, the MEP can only be connected with the MP1 interface supported by the MEC APP, and some MP1 interfaces can be opened in a targeted manner to improve the flexibility of the connection between the MEP and the MEC APP.

Among them, the topology information and selection rules of the MEC APP are manually arranged, registered to the Unified Data Repository (UDR), and forwarded to the PCF by the UDR.

示例性的，如图3所示，可以人工编排该MEC APP的拓扑信息以及选择规则，并将MEC APP的拓扑信息以及选择规则人工注册给UDR，UDR将MEC APP的拓扑信息以及选择规则转发给PCF，然后，PCF根据该网络参数选择相应的会话管理功能(Session Management Function，SMF)，比如，PCF根据该MEC所属的网络切片，进行切片映射，得到网络切片实例，然后，在该网络切片实例内选择相应的SMF，并将该MEC APP的拓扑信息以及网络参数下发给该SMF；SMF根据该网络参数，选择相应的UPF，比如，根据MEC APP所属的网络切片以及DNAI选择匹配的UPF。然后，SMF向该UPF***该MEC APP的实例信息以及上行分流规则。Exemplarily, as shown in Figure 3, the topology information and selection rules of the MEC APP can be manually arranged, and the topology information and selection rules of the MEC APP are manually registered to the UDR, and the UDR forwards the topology information and selection rules of the MEC APP to the UDR. PCF, and then the PCF selects the corresponding session management function (Session Management Function, SMF) according to the network parameters. For example, the PCF performs slice mapping according to the network slice to which the MEC belongs to obtain a network slice instance, and then, in the network slice instance Select the corresponding SMF in the MEC APP, and deliver the topology information and network parameters of the MEC APP to the SMF; the SMF selects the corresponding UPF according to the network parameters, for example, according to the network slice to which the MEC APP belongs and the DNAI to select the matching UPF. Then, the SMF inserts the instance information of the MEC APP and the upstream distribution rule into the UPF.

可以看出，通过以上通信链路的配置，自动化打通了MEC APP、MEP中的多接入边缘计算服务实例以及UPF中的多接入边缘计算服务实例之间的通信链路。如图3所示，每个MEC APP可以在各自的通信链路上进行本地分流，即每个MEC APP在各自的网络域(网络切片)使用相应的网络切片实例，在各自的通信链路上进行本地分流。It can be seen that through the configuration of the above communication links, the communication links between the MEC APP, the multi-access edge computing service instance in MEP, and the multi-access edge computing service instance in UPF are automatically opened. As shown in Figure 3, each MEC APP can perform local offloading on its own communication link, that is, each MEC APP uses the corresponding network slice instance in its own network domain (network slice), on its own communication link Perform local shunting.

应理解，在后续建立用户会话之后，UPF可以接收用户设备的边缘访问请求，根据该边缘访问请求确定该用户设备所要访问的MEC APP的实例信息以及访问时使用的VPN，这样UPF获取与该MEC APP的实例信息对应的上行分流规则，若该VPN符合本地分流条件，则对该用户设备进行本地分流处理，若不符合，则将该用户的数据报文转发到中心侧UPF，从中心侧获取数据内容。It should be understood that after the subsequent establishment of the user session, the UPF can receive the edge access request of the user equipment, and determine the instance information of the MEC APP to be accessed by the user equipment and the VPN used during the access according to the edge access request, so that the UPF obtains and accesses the MEC.
