[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] To facilitate understanding of this application, the following content is first described.

[0052] Please refer to Figure 1 , Figure 1This is the architecture diagram of edge capability open provided by the embodiments of the present invention. As Figure 1 shown, the architecture of edge capability open mainly includes a three-level architecture, namely a network capability open platform, an edge computing management (Edge Computing Management, ECM) platform, and an ECP.

[0053] Among them, the network capability open platform, as a network element in the capability open layer, is used to uniformly open edge computing capabilities and large network capabilities for applications across the network. This large network capability can be understood as core network capabilities, representing the network capabilities supported by the capability network access module such as the Network Exposure Function (NEF) in the core network. In the core network, each network element such as the Access Management Function (AMF), Session Management Function (SMF), Policy Control Function (PCF), and / or Unified Data Management (UDM) can publish functions and events through the NEF. The SMF in the core network can interact with the User Plane Function (UPF) in the core network and the edge UPF, and the UPF in the core network can interact with the edge UPF.

[0054] The ECM platform is a network element in the edge capability access layer, used for aggregating and accessing edge computing capabilities. The ECM platform is connected to the ECP and can manage the ECP. Specifically, in implementation, the ECM platform can be connected to the Business & Operation Support System (BOSS) to support business operations in the BOSS.

[0055] As an example, as Figure 1 shown, the ECM platform can include a first-level ECM platform and a second-level ECM platform. The first-level ECM platform is connected to the second-level ECM platform and can manage the second-level ECM platform. The second-level ECM platform is not directly connected to the network capability open platform and does not belong to the network elements in the edge capability access layer. In specific implementation, it is optional, that is, the second-level ECM platform can be absent, and only the first-level ECM platform exists. For example, the first-level ECM platform can be optionally a national-level ECM platform, and the second-level ECM platform can be optionally a provincial-level ECM platform.

[0056] The ECP is a network element that provides an edge capability enabling layer, used to provide edge capabilities such as edge computing capabilities, and supports network capabilities and vertical industry capabilities. Among them, network capabilities include terminal location capabilities (UE Location), terminal identification capabilities (UE ID, such as mobile subscriber number MSISDN), bandwidth management capabilities, etc., and vertical industry capabilities include video encoding and decoding, image recognition, voiceprint recognition, etc. Both types of capabilities are registered with the API gateway in the form of Application Programming Interfaces (APIs), and provided to applications for invocation in the form of restful API interfaces.

[0057] In specific implementation, the ECP can support the flexible deployment of the operator's own services or third-party applications at the edge of the mobile network. The ECP is carried by the Edge Computing Infrastructure (ECI), provides a running environment and services for various Edge Computing Applications (ECAs) running on it, and is managed by the ECM platform. Communication networks such as 5G networks can open network capabilities to the ECP through the capability open interface based on the API call method. The core function of the ECP is the API gateway.

[0058] It can be understood that the edge capability open solution in this application is not limited to 5G communication systems, but can also be used in 6G communication systems and future extended communication systems.

[0059] Next, in conjunction with the accompanying drawings, the network capability invocation method provided by the embodiments of the present invention will be described in detail through specific embodiments and their application scenarios.

[0060] Please refer to Figure 2 , Figure 2 which is a flowchart of a network capability invocation method provided by an embodiment of the present invention. This method is executed by a network capability invocation system, which may include a network capability open platform, an ECM platform, and multiple ECPs. As Figure 1 shown, the method includes the following steps:

[0061] Step 21: The network capability open platform receives an edge capability invocation request sent by a network application, and forwards the edge capability invocation request to the ECM platform.

[0062] It can be understood that the network application is an application in the network that does not provide edge services and is different from edge applications.

[0063] Step 22: According to the edge capability invocation request, the ECM platform selects a target ECP from multiple ECPs and sends the address information of the target ECP to the network capability open platform.

[0064] Step 23: The network capability open platform sends the address information of the target ECP to the network application.

[0065] Among them, the address information of the target ECP is used for the network application to determine the target ECP and perform edge capability invocation to the target ECP.

[0066] As an example, when a new edge capability of an ECP goes online, it can be sent to the ECM platform in real time through the restful interface between the ECP and the ECM platform. Through the capability registration interface, the ECM platform can register the new available capabilities to the network capability open platform. The ECM platform maintains the location of all ECP nodes in the network and the list of capability APIs deployed on the ECPs.

[0067] In the network capability invocation method of the embodiment of the present invention, the network capability open platform can receive the edge capability invocation request sent by the network application and forward the edge capability invocation request to the ECM platform. Then, according to the edge capability invocation request, the ECM platform can select a target ECP from multiple ECPs and send the address information of the target ECP to the network capability open platform, so that the network capability open platform sends the address information of the target ECP to the network application. Thus, the network application can determine the target ECP and perform edge capability invocation to the target ECP, thereby realizing the network application to invoke the edge capability.

[0068] In the embodiment of the present invention, in order to achieve secure access to the ECP, an authentication mechanism can be introduced to enable the network application to perform edge capability invocation to the ECP based on the authentication information.

[0069] Optionally, the above network capability invocation method may further include: the ECM platform sends the invocation authentication information of the target ECP to the network capability open platform; then, the network capability open platform sends the invocation authentication information to the network application. Among them, the invocation authentication information is used for the network application to perform edge capability invocation to the target ECP based on the invocation authentication information within the valid time of the invocation authentication information. The invocation authentication information is, for example, an invocation authentication identifier, a token, etc. In this way, secure access to the target ECP can be achieved with the help of the invocation authentication information.

[0070] In one implementation, when a network application makes an edge capability call to a target ECP, it can initiate a capability call request that conforms to the call template to the target ECP within the valid time of the call authentication identifier, so as to obtain a call result. The call result can be different in different scenarios. For example, in the scenario of shunt rule subscription, the obtained call result can be a completion identifier, or in the scenario of Quality of Service (QoS) resource application, the obtained call result can be resource indication information, etc.

[0071] In an embodiment of the present invention, in order to facilitate the ECM platform to select a suitable target ECP, the above-mentioned edge capability call request may include the location information of the network application. The ECM platform may select a target ECP from multiple ECPs according to the location information of the network application and the following content:

[0072] The deployment locations of multiple ECPs;

[0073] The status information of multiple ECPs.

[0074] Optionally, the status information of the multiple ECPs may include at least one of the following:

[0075] The load conditions of the multiple ECPs;

[0076] The called frequencies of the multiple ECPs;

[0077] The availability of the multiple ECPs.

[0078] In one implementation, the ECM platform may select an optimal capability node as the target ECP from multiple ECPs according to the location information of the network application, in combination with the deployment locations, availability, and load conditions of the multiple ECPs.

[0079] In an embodiment of the present invention, the ECP may proxy the ECA to call the core network capabilities, which is implemented by the core function API gateway of the ECP. The API gateway is the unified entry for the ECA to call network capabilities and can simultaneously complete authentication, measurement of call times / frequencies, traffic control, etc. Through the proxy call of the API gateway, unified management of the unified entry for edge capabilities and core network capabilities can be achieved. Among them, the prerequisite for the ECP to proxy the ECA to initiate a capability call request to the network capability open platform is that the ECA has been registered on the capability open platform. The ECA can obtain a list of all callable capabilities through the API gateway in the ECP, including the core network capabilities from the network capability open platform.

[0080] Optionally, the above network capability invocation method may further include: First, the ECP receives a capability invocation request initiated by an edge application and forwards the capability invocation request to the network capability open platform; then, the network capability open platform performs invocation processing according to the capability invocation request and sends the invocation result to the ECP; finally, the ECP sends the invocation result to the edge application. The invocation result may be different in different scenarios. For example, in the scenario of shunt rule subscription, the obtained invocation result may be a completion identifier, or in the scenario of QoS resource application, the obtained invocation result may be resource indication information, etc.

[0081] In this way, through the proxy of the ECP, the edge application can invoke the core network capabilities.

[0082] The following Figures 3 to 5 will describe the embodiments of the present invention in detail.

[0083] In the embodiments of the present invention, in combination with Figure 3 as shown, the process of the edge application invoking the core network capabilities may include the following steps:

[0084] S1: The ECA initiates a capability invocation request to the ECP.

[0085] S2: After the ECP identifies that the current invocation belongs to the proxy capability invocation, it identifies the ECA identifier that initiates the invocation and forwards the capability invocation request to the network capability open platform. Optionally, the ECP may control the invocation according to a preset flow control rule.

[0086] S3: After receiving the capability invocation request from the ECP, the network capability open platform performs invocation processing after passing authentication and sends the invocation result to the ECP. It can be understood that, as Figure 3 shown, when the network capability open platform performs invocation processing, it may be implemented through the NEF based on network functions in the core network such as UDM, UDR, and / or PCF, etc.

[0087] S4: The ECP returns the invocation result to the corresponding ECA and records the invocation information.

[0088] In the embodiments of the present invention, in combination with Figure 4 and Figure 5 as shown, the process of the network application invoking the edge capabilities may include the following steps:

[0089] S1: The network application initiates an edge capability invocation request to the network capability open platform, and the request includes the location information of the network application such as the IP address. The request is, for example, a Hypertext Transfer Protocol http request.

[0090] S2: The network capability exposure platform forwards the edge capability call request including location information to the ECM platform.

[0091] S3: After receiving the edge capability call request, the ECM platform matches the ECP's deployment location, availability, load, etc. according to the location information of the network application, and selects an optimal capability node as the target ECP.

[0092] S4: The ECM platform sends a call instruction and capability call token to the target ECP.

[0093] S5: The ECM platform returns the address information and token of the target ECP to the network capability exposure platform.

[0094] S6: The network capability exposure platform returns the address information and token of the target ECP to the network application.

[0095] S7: The network application carries the token within the validity period of the token and initiates a capability call request that complies with the call template to the target ECP.

[0096] S8: The target ECP responds to the capability call of the network application and returns the call result. The capability call can be completed with a single result return or may require multiple data transmissions.

[0097] S9: After the call is completed, the target ECP counts the call results and returns the end character to the ECM platform.

[0098] S10: The ECM platform forwards the end character to the network capability exposure platform to complete an edge capability calling process.

[0099] It should be noted that when new edge capabilities of ECP are launched, they need to be sent to the ECM platform in real time through the restful interface between the ECP and the ECM platform. The ECM platform registers the new available capabilities to the network capability exposure platform through the capability registration interface. The ECM platform maintains the location of ECP nodes in the entire network and the capability API list deployed on the ECP.
