[0059] In the system framework of edge computing, the UPF is deployed at the network edge to offload user traffic accessing edge services deployed on the ECP. The methods for issuing edge computing traffic offloading strategies include: (1) static configuration, i.e., issuing to the UPF through the SMF, or configuring through the UPF network management system; (2) dynamic configuration. The capabilities that can be opened on the ECP include network capabilities and industry capabilities. Both types of capabilities are exposed in the form of application programming interfaces (APIs) on the API gateway. Furthermore, the capabilities of each ECP are uniformly aggregated to the ECM and then opened to large network applications through the capability opening platform.
[0060] Furthermore, in practical applications, such as Figure 1As shown, large-scale network applications can access edge network capabilities provided on the ECP through the capability open platform, ECM, and ECP. Alternatively, they can access core network capabilities such as Quality of Service (QoS) and voice messaging through the capability open platform, Network Exposure Function (NEF), and 5G core network (5GC). When a large-scale network application initiates a request for a composite capability to the capability open platform, it needs to go through the configuration process of the regional core network. After the network traffic offloading policy takes effect, the corresponding edge capability policy is then issued. Once both policies are in effect, the NEF replies to the capability open platform with the composite capability call result, and the central application pays based on the call result.
[0061] In other words, in related technologies, the scheduling channels for network traffic offloading strategies and edge capability strategies are separate, making it difficult to guarantee consistency in policy execution and ensuring that the application instance offloaded is consistent with the application instance selected by the ECM. Furthermore, since the ECM does not know the UPF that the user is connected to, nor can it perceive the user's online status, the user may not be online during large-scale network scheduling, leading to inaccurate billing.
[0062] Based on this, in various embodiments of this application, through a first communication interface set between the ECP and the UPF, the first ECP, upon receiving first information from the ECM, sends second information to each of at least one first UPF; wherein, the first information includes at least a first capability invocation indication; the first capability invocation indication is used to instruct the first ECP to provide capabilities for the first application; the second information is used at least to configure the first UPF to route the corresponding capability invocation request to the first ECP. By defining a first communication interface between the ECP and the UPF, the ECP can configure a routing strategy for the corresponding UPF through the first communication interface, thereby ensuring that the application instance routed through the UPF is consistent with the application instance selected by the ECM.
[0063] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.
[0064] Figure 2 This illustration shows an architecture diagram applicable to the capability invocation configuration scheme provided in the embodiments of this application, such as... Figure 2 As shown, a new capability open interface Mp2 is defined between ECP and UPF. Through the Mp2 interface, ECP can issue corresponding API gateway or application traffic offloading policies to UPF.
[0065] based on Figure 2 The illustrated architecture diagram shows that this application provides a configuration method for capability invocation, such as... Figure 3As shown, this method is applied to the first ECP and includes:
[0066] Step 301: Upon receiving the first information from the ECM, send the second information to each of the at least one first UPFs through the first communication interface.
[0067] The first communication interface is Figure 2 The Mp2 interface is located between the ECP and the UPF; the first information includes at least a first capability call indication; the first capability call indication is used to instruct the first ECP to provide capabilities to the first application; the second information is used to configure the first UPF to route the corresponding capability call request to the first ECP.
[0068] In practical applications, a large network application requests a composite capability call request from the capability open platform to enable a composite capability call for a specific user, and includes the application's IP address in the composite capability call request. The capability open platform forwards this composite capability call request, which includes the IP address, to the ECM. Based on the received composite capability call request, the ECM selects the first ECP that can provide the best capability from among multiple ECPs, based on the IP address carried in the composite capability call request, and according to the ECP's location information, status information, and load conditions, and sends first information to the first ECP. Here, the first information includes at least a first capability call instruction.
[0069] Based on the first capability call instruction, the first ECP sends second information to each of the at least one first UPFs connected to the first ECP through the first communication interface. The second information is used to configure the corresponding first UPF to route the corresponding capability call request to the first ECP.
[0070] In practical applications, the second information sent by the first ECP to the first UPF through the first communication interface is not limited to configuring the first UPF to route corresponding capability call requests to the first ECP. It may also include Domain Name Resolution (DNS) rules, used to configure the mapping relationship between the IP address and domain name of the large network application on the UPF; bandwidth management capabilities, used to control the bandwidth limit for specific users to access applications through the UPF; blacklist and whitelist capabilities, to restrict or open user access to applications through blacklists and whitelists in the UPF; and terminal identification query requests, used by the ECP to obtain the unique identifier of the terminal from the UPF.
[0071] In one embodiment, the first information further includes at least one of the following:
[0072] The IP address of the first application;
[0073] The port of the first application;
[0074] Call the token.
[0075] Since only legitimate users can successfully invoke capabilities, the ECM can use a call token to inform the first ECP of the caller's identity information, ensuring that legitimate users will not be rejected when initiating calls subsequently.
[0076] For example, the first information sent by ECP to UPF includes, but is not limited to, the information listed in Table 1:
[0077] Table 1
[0078]
[0079] In one embodiment, the method further includes:
[0080] Through the first communication interface, a first response regarding the second information is received from at least one of the at least one first UPFs.
[0081] Based on the received first response, a third message is sent to the first application.
[0082] The first response indicates that the first UPF has successfully configured the second information, and the third information indicates the result of the first application's capability invocation.
[0083] Here, after the first UPF successfully configures itself based on the second information, it returns a first response to the first ECP. In this way, the first ECP can determine which first UPFs have successfully configured themselves based on the second information based on the received first response. Subsequently, based on the received first response, the first ECP sequentially returns third information representing the capability invocation result to the first application. Thus, the first application, based on the third information sent by the first ECP, invokes the capability from the first ECP.
[0084] In one embodiment, the method further includes:
[0085] Upon completion of the capability invocation of the first application, a fourth message is sent to each of the at least one first UPFs via the first communication interface; the fourth message is used to configure the first UPF to delete the configuration related to the second message.
[0086] After the first application completes the capability call to the first ECP, the billing is completed accordingly. The ECM side issues an instruction to delete the traffic splitting policy configuration. The first ECP issues fourth information to each of the at least one first UPF to configure the corresponding UPF to delete the configuration related to the second information, that is, to instruct the first UPF to delete the corresponding traffic splitting policy.
[0087] Correspondingly, embodiments of this application also provide a configuration method for capability invocation, such as... Figure 4 As shown, this method is applied to the first UPF and includes:
[0088] Step 401: Receive the second information sent by the first ECP through the first communication interface.
[0089] The first communication interface is located between the ECP and the UPF; the second information is at least used to configure the first UPF to route the capability call requests related to the first application to the first ECP.
[0090] In practical applications, a large network application requests a composite capability call request from the capability open platform to enable a composite capability call for a specific user, and includes the application's IP address in the composite capability call request. The capability open platform forwards this composite capability call request, which includes the IP address, to the ECM. Based on the received composite capability call request, the ECM selects the first ECP that can provide the best capability from among multiple ECPs, based on the IP address carried in the composite capability call request, and according to the ECP's location information, status information, and load conditions, and sends first information to the first ECP. Here, the first information includes at least a first capability call instruction.
[0091] Based on the first capability call instruction, the first ECP sends second information to each of the at least one first UPFs that it is connected to. The second information is used to configure the corresponding first UPF to route the corresponding capability call request to the first ECP.
[0092] In one embodiment, the method further includes:
[0093] If the second information is successfully configured, a first response is returned to the first ECP through the first communication interface.
[0094] The first response indicates that the first UPF has successfully configured the second information.
[0095] Here, after the first UPF successfully configures itself based on the second information, it returns a first response to the first ECP. In this way, the first ECP can determine which first UPFs have successfully configured themselves based on the second information based on the received first response. Subsequently, based on the received first response, the first ECP sequentially returns third information representing the capability invocation result to the first application. Thus, the first application, based on the third information sent by the first ECP, invokes the capability from the first ECP.
[0096] In one embodiment, the method further includes:
[0097] The system receives the fourth information sent by the first ECP through the first communication interface; the fourth information is used to configure the first UPF to delete the configuration related to the second information.
[0098] Based on the fourth information, the configuration related to the second information is deleted.
[0099] After the first application completes the capability call to the first ECP, the billing is completed accordingly. The ECM side issues an instruction to delete the traffic splitting policy configuration. The first ECP issues fourth information to each of the at least one first UPF to configure the corresponding UPF to delete the configuration related to the second information, that is, to instruct the first UPF to delete the corresponding traffic splitting policy.
[0100] In one embodiment, the method further includes:
[0101] The traffic splitting strategy successfully configured based on the second information is sent to the SMF via the second communication interface.
[0102] The second communication interface is located between the UPF and the SMF.
[0103] In related technologies, the traffic splitting strategy of UPF is issued by SMF. Here, by adding a second communication interface between UPF and SMF, UPF will send the traffic splitting strategy configured and effective through the Mp2 interface to SMF. In this way, SMF can control UPF's traffic splitting strategy and ensure the accuracy of differentiated billing.
[0104] It should be noted that, based on the enhanced interface added between UPF and SMF as described above, the configuration of the traffic splitting strategy provided in the embodiments of this application can be achieved, and it can also be used to configure DNS rules or implement other enhanced management and control capabilities.
[0105] The present application will be further described in detail below with reference to application examples.
[0106] In this application embodiment, from Figure 5 The architecture diagram shows that Mp2 interfaces are defined between ECP and UPF 1, and between ECP and UPF 2, based on... Figure 5 The architecture shown, along with the corresponding edge network policy configuration and composite capability invocation process, is as follows: Figure 6 As shown:
[0107] Step 1: The big network application sends a composite capability call request to the capability open platform, requesting to enable composite capabilities for user 1342639XXXX. The composite capability call request carries the IP address.
[0108] Step 2: The capability open platform forwards the composite capability call request to ECM.
[0109] Step 3: EMC determines the target ECP based on factors such as the ECP's location information, edge capability status information, load conditions, call frequency, and availability.
[0110] Step 4: The ECM sends a capability call instruction, a capability call token, and the IP address of the corresponding capability to the target ECP.
[0111] Step 5: ECP configures the traffic offloading policy to UPF 1 through the capability open interface.
[0112] Step 6: UPF 1 returns a configuration success response to ECP.
[0113] Step 7: ECP configures the traffic offloading policy to UPF 2 through the capability open interface.
[0114] Step 8: UPF 2 returns a configuration success response to ECP.
[0115] Step 9: ECP returns the traffic offloading strategy and industry capacity scheduling results to the main network application in the order of successful UPF configuration.
[0116] Step 10: Capability call ends, billing is completed, ECM sends the traffic distribution policy to ECP, and deletes the configuration.
[0117] Step 11: ECP sends the configuration for deleting the traffic splitting policy to UPF 1 and UPF 2 respectively.
[0118] In the capability invocation configuration method, apparatus, network node, and storage medium provided in this application embodiment, through a first communication interface set between ECP and UPF, the first ECP, upon receiving first information issued by ECM, issues second information to each of at least one first UPF; wherein, the first information includes at least a first capability invocation indication; the first capability invocation indication is used to instruct the first ECP to provide capabilities for a first application; the second information is at least used to configure the first UPF to route the corresponding capability invocation request to the first ECP. By defining a first communication interface between the ECP and UPF, the ECP can configure traffic offloading policies for the corresponding UPF through this interface. Using this scheme, for composite capability requests from large-scale network applications, the ECM simultaneously handles network policy and industry capability scheduling. When a large-scale network application requests composite capability scheduling, it carries an IP address representing the terminal's location region. The ECM prioritizes selecting industry capability nodes (ECPs) based on the IP address. The ECM sends the selected node's industry capability offloading information to the ECP via the southbound management interface. The ECP initiates traffic offloading policy configuration requests to the UPFs it interfaces with via the MP2 interface, directly exposing the edge network capabilities on the ECP to industry applications. In this way, the configuration of edge network capabilities does not need to go through the traffic offloading policy configuration process of the regional core network, achieving a local closed loop. This ensures that the application instances offloaded through the UPF are consistent with the application instances selected by the ECM.
