[0043] When an application needs to use a network capability, an application server submits a capability ordering request to a management platform, and the network capability is called after the capability ordering request is granted. Along with the development and deployment of edge computing, more and more network capabilities are deployed at a network edge. In the related art, with respect to the network capability deployed at the network edge, on one hand, different applications have different service requirements on a same network capability, but an operator fails to consider how to perform the performance evaluation on the network capability and provide capability classifications for different service requirements based on the evaluation. On the other hand, when the network capability is provided for the application, usually proximate matching is performed in accordance with a distance between the application server and a position where the network capability is deployed. In addition when the application server is switched, the proximate matching is also performed, without considering whether the called network capability meets the service requirement on the application. In a word, in the related art, there is a problem that the called network capability does not match the service requirement of the application.

[0044] Based on the above, the present application provides a capability calling method, a capability calling device, a network node and a storage medium. A first capability is deployed on at least two second nodes, a first network node determines a capability classification corresponding to the first capability on each of the at least two second network nodes based on at least one parameter, and a third network node orders and calls the first capability corresponding to the first capability classification in accordance with the capability classification corresponding to the first capability. As a result, it is able to order and call the capability in a diversified manner, thereby to enable the called capability to match a service requirement of an application.

[0045] The present application will be described hereinafter in more details in conjunction with the drawings and embodiments. It should be appreciated that, in the embodiments of the present application, a capability may be a network capability deployed by an operator at a network edge, i.e., an edge network capability, or a capability deployed by a third-party application at the network edge, e.g., a face recognition function.

[0046] The present application provides in some embodiments a capability calling method for a first network node. Here, the first network node is a management platform, also called as an edge capability management platform or an edge capability open management platform. As shown in FIG. 1, the method includes Step 101 of classifying a capability classification corresponding to a first capability on each of at least two second network nodes in accordance with at least one parameter.

[0047] The first capability is deployed on the at least two second network nodes, and a third network node orders and calls the first capability corresponding to a first capability classification.

[0048] For example, the first capability is a network capability such as a wireless positioning capability, user identification, a bandwidth management capability, a Radio Network Information Services (RNIS), a flow-splitting capability, a cloud game or video encoding/decoding, or a face recognition function deployed by a third-party application. The second network node is a network node where the first capability is deployed, usually a Multi-access Edge Computing MEC) platform. In actual use, the second network node is an Application Programming Interface (API) Gateway (GW) at a network edge. The first network node, as a capability management platform, determines the capability classification corresponding to the first capability on each second network node, so as to provide the first capability with different capability classifications for different applications. The third network node orders and calls the first capability corresponding to the first capability classification to the first network node in accordance with the capability classification corresponding to the first capability.

[0049] In an embodiment of the present application, in the case that the first capability is a network capability, the at least one parameter includes at least one of a position of a corresponding second network node, an access capacity of the corresponding second network node with respect to the first capability, a response delay of the corresponding second network node with respect to the first capability, or performance of the first capability deployed on the corresponding second network node.

[0050] The position of the second network node is just a position in a network where the second network node is located, and it is used to indicate a network distance between the second network node and a wireless side. The access capacity and the response delay depend on the second network node itself, e.g., the performance of the API GW or a configured Edge Computing Platform (ECP) resource. The performance of the first capability depends on the performance of the first capability deployed on the second network node. For example, for the wireless positioning capability, different positioning accuracy is required on different second network nodes. The first network node determines the capability classification corresponding to the first capability on each second network node in accordance with the at least one parameter.

[0051] In actual use, a capability classification function is newly added in the first network node, and when a capability is to be registered in the management platform, a capability classification of the capability is determined and stored by the first network node.

[0052] In an embodiment of the present application, the determining, in accordance with the at least one parameter, the capability classification corresponding to the first capability on each of the at least two second network nodes includes, when registering the first capability, determining, in accordance with the at least one parameter, the capability classification corresponding to the first capability on each of the at least two second network nodes.

[0053] In an embodiment of the present application, the capability calling method further includes sending first information to the third network node and each of the at least two second network nodes, the first information is used to indicate the capability classification corresponding to the first capability on each of the at least two second network nodes, and the third network node is a network node for ordering and calling the first capability.

[0054] In this regard, the third network nodes initiates a request to a corresponding network node in accordance with the first information so as to call the first capability, and the second network node determines the capability classification corresponding to the first capability deployed locally at the second network node in accordance with the first information.

[0055] As shown in FIG. 2, a network capability registration procedure includes the following steps.

[0056] Step 1: initiating a registration request carrying capability information to the edge capability open management platform (i.e., the first network node), so as to request to register a corresponding network capability.

[0057] Step 2: classifying, by the edge capability open management platform, a capability classification corresponding to the network capability on each deployed API GW (i.e., second network node) in accordance with at least one parameter, and storing, by the edge capability open management platform, the level information.

[0058] Here, the edge capability open management platform stores level information about the network capability, apart from registration information about the network capability, i.e., a capability identifier.

[0059] Step 3: sending, by the edge capability open management platform, capability registration success information carrying the level information to each API GW.

[0060] Step 4: locally maintaining, by each API GW, relevant information about the network capability in accordance with the level information, the relevant information including level information corresponding to the network capability locally deployed on each API GW.

[0061] Table 1 shows the level information stored in the first network node. As shown in Table 1, a network capability 1 corresponding to a first level is deployed on both an API GW 1 and an API GW 2. In addition, a network capability 2 corresponding to a second level is further deployed on the API GW 1.

[0062]

TABLE 1
Capability identifier	Deployment position	Level information
Capability 1	API GW1	First level
Capability 1	API GW2	First level
Capability 2	API GW1	Second level

[0063] Table 2 shows the level information stored in the API GW 1, and the level information is determined by the API GW 1 in accordance with the first information sent by the management platform. The level information is related to the network capabilities deployed on the API GW 1, including the network capability 1 corresponding to the first capability classification and the network capability 2 corresponding to the second capability classification deployed on the API GW 1. In addition, a specific deployment path of each network capability on the API GW 1 is recorded at a corresponding deployment position.

[0064]

TABLE 2
Capability identifier	Deployment position	Level information
Capability 1	API GW 1.xx	First level
Capability 2	API GW 2.xxx	Second level

[0065] After determining the capability classifications of the first capability, the third network node may specifically order a capability classification of the first capability. In addition, when storing a capability ordering record of the third network node, the first network node needs to store the capability classification ordered by the third network node besides the capability ordered by the third network node, and send the capability ordering record to each second network node, so that the third network node conveniently calls the capability subsequently.

[0066] Based on the above, in an embodiment of the present application, the method further includes storing second information and sending the second information to each of the at least two second network nodes, and the second information is used to indicate a network capability ordered by a third network node and a capability classification corresponding to the ordered network capability.

[0067] Here, when the first network node or any second network node has received the request for calling the first capability from the third network node, it determines that the third network node has ordered the first capability in accordance with the second information, further determines the capability classification corresponding to the first capability ordered by the third network node in accordance with the second information, and then calls the first capability corresponding to the capability classification for the third network node.

[0068] Table 3 shows the second information sent by the first network node. As shown in Table 3, the capability 1 corresponding to the capability classification 1 is ordered by an application 1 and an application 2.

[0069]

	TABLE 3
	Application information	Capability ordering information
	Application 1	Capability 1-first level
	Application 2	Capability 1-first level

[0070] In an embodiment of the present application, the method further includes: receiving a first request from the third network node, the first request being used to request to call the first capability: in the case that the first capability corresponding to a first capability classification is determined to be ordered by the third network node, generating a first list, the first list including at least one of the at least two second network nodes, and the first capability classification being a capability classification corresponding to the first capability on the second network node in the first list; and sending third information to the third network node in accordance with the first list, the third information being used to indicate one second network node in the first list, to enable the third network node to send the first request to the second network node indicated by the third information.

[0071] When the third network node calls the first capability, at first whether the first capability corresponding to the first capability classification is locally deployed, i.e., whether the first capability corresponding to the first capability classification is deployed on an API GW to which the third network node as an application server accesses, is determined based on the first information sent by the first network node. When the first information indicates that the first capability corresponding to the first capability classification fails to be locally deployed, the third network node sends the first request to the first network node. After determining that the first capability corresponding to the first capability classification is determined to be ordered by the third network node in accordance with the second information, the first network node determines the second network node where the first capability corresponding to the first capability classification is deployed in accordance with the first information, and then generates the first list in accordance with the determined second network node.

[0072] In an embodiment of the present application, the generating the first list includes generating the first list in accordance with a distance between the second network node and the third network node.

[0073] In actual use, when generating the first list, the first network node needs to consider the distance between the second network node and the third network node, so as to ensure as possible that the distance between the third network node and the second network node in the first list is within an appropriate range, thereby to call the first capability more rapidly.

[0074] In an embodiment of the present application, the capability calling method further includes determining the third information in accordance with at least one real-time performance parameter of each second network node in the first list, and the at least one real-time performance parameter includes at least one of an occupancy rate, a response delay, or an upstream rate or downstream rate.

[0075] Here, when the second network node in the first list is selected for the third network node, real-time state information about the second network node is considered. In the case that each first capability being provided corresponds to the first capability classification, the second network node in an optimum real-time state is selected, so that the selected second network node provides the optimum first capability for the third network node.

[0076] In actual use, a corresponding functional module is deployed on the first network node, so as to achieve a function of an edge scheduling center, receive the first list from the management platform, obtain the real-time state of each second network node in the first list, and sends the obtained real-time state to the management platform.

[0077] The present application further provides in some embodiments a capability calling method for any second network nodes in at least two second network nodes. A first capability is deployed on each of the at least two second network nodes. As shown in FIG. 3, the capability calling method includes: Step 301 of receiving first information sent by a first network node; and Step 302 of determining a capability classification corresponding to the first capability in accordance with the first information. The first information is used to indicate the capability classification corresponding to the first capability on each of the at least two second network nodes, and the capability classification is classified by the first network node in accordance with at least one parameter.

[0078] Here, the second network node may be each API GW at a network edge. The first network node, as a capability management platform, determines the capability classification corresponding to the first capability on each second network node. The second network node receives the first information sent by the first network node, and determines therefrom the capability classification corresponding to the first capability deployed locally at the second network node. Based on the determined capability classification, the first capability corresponding to different capability classifications is provided for different applications. The third network node, i.e., an application server, orders and calls the first capability corresponding to the first capability classification to the first network node in accordance with the capability classification corresponding to the first capability when ordering the first capability to the first network node.

[0079] In an embodiment of the present application, the method further includes: receiving a first request sent by a third network node, the first request being used to request to call the first capability; and calling the first capability corresponding to a first capability classification for the third network node in accordance with the first request. The first request is sent by the third network node in the case of determining that the first capability with the first capability classification has been deployed on the second network node.

[0080] In actual use, in the case that the third network node determines that the first capability corresponding to the first capability classification is deployed on the second network node, the third network node sends the first request to the second network node, so as to call the first capability corresponding to the first capability classification in accordance with the first request. Here, the second network node which has received the first request is a network node to which the third network node accesses, or any other second network node.

[0081] In an embodiment of the present application, the method further includes receiving second information sent by the first network node, the second information is used to indicate a network capability ordered by the third network node and a capability classification corresponding to the ordered network capability. The calling the first capability corresponding to the first capability classification for the third network node in accordance with the first request includes, in the case that the first capability corresponding to the first capability classification is determined through the second information to be ordered by the third network node, calling the first capability corresponding to the first capability classification for the third network node in accordance with the first request.

[0082] Upon the receipt of the first request from the third network node, the second network node calls the first capability corresponding to the first capability classification for the third network node in accordance with the first request after the second network node determines that the first capability corresponding to the first capability classification is determined to be ordered by the third network node in accordance with the second information.

[0083] The present application further provides in some embodiments a capability calling method for a third network node. In actual use, the third network node is an application server. As shown in FIG. 4, the method includes Step 401 of ordering a first capability corresponding to a first capability classification to a first network node. The first capability is deployed on at least two second network nodes, and a capability classification corresponding to the first capability on each of the at least two second network nodes is classified by the first network node in accordance with at least one parameter.

[0084] For example, the first capability is a network capability such as a wireless positioning capability, user identification, a bandwidth management capability, an RNIS, a flow-splitting capability, a cloud game or video encoding/decoding, or a face recognition function deployed by a third-party application. The second network node is a network node where the first capability is deployed, usually an MEC platform. In actual use, the second network node is an API GW at a network edge. The first network node, as a capability management platform, determines the capability classification corresponding to the first capability on each second network node, so as to provide the first capability with different capability classifications for different applications. The third network node, i.e., an application server, orders and calls the first capability corresponding to the first capability classification to the first network node in accordance with the capability classification corresponding to the first capability.

[0085] In an embodiment of the present application, the method further includes: receiving first information sent by the first network node, the first information being used to indicate the capability classification corresponding to the first capability on each of the at least two second network nodes; and sending a first request to a corresponding network node in accordance with the first information, the first request being used to request to call the first capability.

[0086] When the third network node calls the first capability, at first whether the first capability corresponding to the first capability classification is locally deployed, i.e., whether the first capability corresponding to the first capability classification is deployed on an API GW to which the third network node as an application server accesses, is determined based on the first information sent by the first network node. When the first information indicates that the first capability corresponding to the first capability classification fails to be locally deployed, the third network node sends the first request to the first network node. After determining that the first capability with the first capability classification is determined to be ordered by the third network node in accordance with the second information, the first network node determines the second network node where the first capability corresponding to the first capability classification is deployed in accordance with the first information, and then generates a first list in accordance with the determined second network node.

[0087] Based on the above, in an embodiment of the present application, the sending the first request to the corresponding network node in accordance with the first information includes: in the case that the first information indicates that the first capability corresponding to the first capability classification is deployed on a fourth network node, sending the first request to the fourth network node, the fourth network node being a network node which accesses to a same local area network as the third network device; and in the case that the first information indicates that the first capability corresponding to the first capability classification is not deployed on the fourth network node, sending the first request to the first network node, receiving third information sent by the first network node, and sending the first request to the second network node indicated by the third information. The third information is used to indicate one second network node in the first list, the first list includes at least one of the at least two second network nodes, and a capability classification corresponding to the first capability on the second network node in the first list matches the first capability classification.

[0088] In actual use, when generating the first list, the first network node needs to consider the distance between the second network node and the third network node, so as to ensure as possible that the distance between the third network node and the second network node in the first list is within an appropriate range, thereby to call the first capability more rapidly. In addition, when the second network node in the first list is selected for the third network node, real-time state information about the second network node is considered. In the case that the first capability being provided corresponds the first capability classification, the second network node in an optimum real-time state is selected, so that the selected second network node provides the optimum first capability for the third network node.

[0089] As shown in FIG. 5, a network capability calling procedure includes the following steps.

[0090] At first, in the case that the first network capability with the first capability classification is deployed on a local API GW of an edge application (e.g., the third network node), the following steps a1 to a3 are performed.

[0091] Step a1: initiating, by the edge application, a capability calling request to the local API GW.

[0092] Step a2: inquiring, by the local API GW, a capability ordering record, so as to determine that the first network capability with the first capability classification is ordered by the edge application.

[0093] Step a3: sending, by the local API GW, a capability calling result to the edge application.

[0094] Next, in the case that the first network capability with the first capability classification is not deployed on the local API GW of the edge application (e.g., the third network node), the following steps b1 to b5 are performed.

[0095] Step b1: initiating, by the edge application, a capability calling request to an edge capability open management platform (i.e., the first network node).

[0096] Step b2: generating, by the edge capability open management platform, a first list that meets a condition in accordance with the capability ordering record and a position of the edge application.

[0097] Step b3: sending, by the edge capability open management platform, the first list to an edge capability scheduling center.

[0098] Step b4: sending, by the edge capability scheduling center, a network node with an optimum real-time state to the edge capability management platform in accordance with the first list and a real-time state of each network node in the first list.

[0099] The edge capability scheduling center inquires the real-time state to each MEC platform in real time, so as to determine the real-time state of each network node.

[0100] Step b5: sending, by the edge capability management platform, a capability calling result to the edge application.
