[0040] Note that example implementations can be implemented in various forms and should not be construed as being limited to the examples set forth herein.

[0041] For ease of understanding, the related art and terms involved in the present disclosure are first explained as follows.

[0042] UE (User Equipment, user equipment) is also called a user terminal, and is an access terminal of a mobile network and a granularity for implementing mobility management and session management of a mobile network.

[0043] UPF (User Plane Function, user plane function) is a network function for performing user plane policy and forwarding user data of a 5G core network.

[0045] EAS (Edge Application Server, edge application server).

[0046] EASDF (EAS Discovery Function, EAS discovery function) is a network function introduced by a 5GC core network to support edge application addressing.

[0047] DNS (Domain Name System, domain name server), provides domain name resolution service.

[0048] eDNS, refers to a processing manner of carrying additional information in a reserved field of a DNS packet in a negotiated manner.

[0049] MEC (Multi-access Computing, multi-access edge computing), a scenario of providing a nearby service at the network edge, and when used independently, usually refers to an MEC edge node or an EDN (Edge Data Network) in an MEC system, on which an edge application is deployed.

[0052] MEO (MEC Orchestrator), a management entity for implementing unified orchestration management of resources in an MEC system or life cycle management of an application.

[0053] NMS (Network Management System), in the embodiments of the present disclosure, is a unified network management of a network, and has management functions of performance, configuration, monitoring, alarm, security, etc. of a core network, a transmission network, a wireless network, etc.

[0054] NWDAF (Network Data Analytics Function, data analysis function introduced in a 5G core network), performs functions of collecting data from peripheral network elements, management units, etc., and performing data analysis, provides policy decision basis, network optimization basic data, or other control policy data, etc. according to analysis results, and can open authorized analysis data to the outside.

[0055] SMF (Session Management function), session management function, is responsible for tunnel maintenance, IP address allocation and management, UP function selection, policy implementation and control in QoS, charging data collection, roaming, etc.

[0056] The traditional addressing method of mobile Internet is domain name addressing. After the introduction of mobile edge computing, the domain name resolution of distributed edge application mainly considers the location information of user access. With the expansion of mobile services, many services need to rely on sufficient computing power to ensure low processing delay and good processing effect. Therefore, it is not enough to rely on location for addressing of distributed application.

[0057] As shown in Figure 1 The current known method is that the core network element EASDF carries the terminal location information in the eDNS enhancement field by performing eDNS processing on the DNS request packet, thereby providing the user location information for the external DNS system. According to the location information of the terminal, the DNS can resolve to the nearest application instance of the user, but cannot guarantee that the resource condition of the application instance is optimal, thereby cannot guarantee the ideal user experience.

[0058] In the MEC system architecture, the orchestration management function MEO has a unified view of the computing resources and applications in the whole network, but is mainly responsible for orchestration and life cycle management, and does not fully play the important role of having a unified view.

[0059] The method, device, equipment and medium provided by the embodiment of the disclosure can solve the defects of the current edge application addressing by combining the capability of MEO.

[0060] The embodiment of the disclosure provides an edge application addressing method based on computing power. An EASDF pre-configures the MEO address of the MEC system corresponding to the edge application. A network management system NMS and / or a data analysis network element NWDAF continuously collects network data and analyzes connection performance. As shown in Figure 2 The method based on computing power provided by the embodiment of the disclosure includes steps S202-S208.

[0061] In S202, after receiving the DNS request of the distributed application forwarded by the EASDF, the MEO obtains the location information of the UE.

[0062] In some embodiments, the DNS request is forwarded by the EASDF to the corresponding MEO according to the domain name information in the DNS request, and the EASDF performs eDNS processing on the DNS request message and carries the location information of the UE in the eDNS information.

[0063] In some embodiments, the MEO obtains the location information of the UE, including: in the case that the DNS request carries the location information of the UE, the MEO obtains the location information of the UE from the DNS request; in the case that the DNS request does not carry the location information, the MEO queries the location information of the UE from the network.

[0064] In S204, the MEO queries the N application access paths of the UE and the performance of the N application access paths based on the location information of the UE through the NMS, the NWDAF, or the SMF associated with the current session of the UE.

[0065] The N application access paths are possible application access paths of the UE, one end of the N application access paths is the UE, and the other end is an edge node that provides services for the UE, and N is a positive integer.

[0066] The N application access paths are feasible paths of the UE to the edge node that provides services for the UE. In some embodiments, the above-mentioned S204 can be that the MEO queries the N application access paths of the UE and the performance of the N application access paths based on the location information of the UE through the NMS or the NWDAF; in the case where neither the NMS nor the NWDAF has the information of the application access paths of the UE, the NMS or the NWDAF subscribes to or queries the N application access paths of the UE and the performance of the N application access paths to the SMF associated with the current session of the UE.

[0067] In S206, the target application instance is determined in combination with the application access paths and the performance of the paths and the unified view information of the applications and resources possessed by the MEO.

[0068] In some embodiments, the unified view information of the applications and resources includes the application deployment situation of the edge nodes and the resource situation of each edge node.

[0069] In some embodiments, the unified view information of the applications and resources further includes the demand information of the applications.

[0070] In S208, the IP address of the target application instance and the edge anchor point information are returned to the EASDF, so that the EASDF feeds back the IP address of the target application instance to the UE through a DNS response.

[0071] In some embodiments, the above-mentioned edge application addressing method based on computing power can further include that in the case where the currently deployed application instance cannot meet the performance requirement of the access service, the MEO adjusts the resources of the service node or starts a new application instance on the node.

[0072] In some embodiments, the above-mentioned edge application addressing method based on computing power can further include that in the case where the currently deployed application instance cannot meet the performance requirement of the access service and the resources of the service node do not meet the demand of the new instance, a suboptimal node that meets the demand is selected.

[0073] In some embodiments, the above-mentioned edge application addressing method based on computing power can further include that in the case where the current session path of the UE is not the path corresponding to the edge anchor point, user plane relocation is triggered.

[0074] The embodiment of the present disclosure can solve the problem that the addressing of distributed edge application needs to comprehensively consider the computing resource of service node, fully reuse the understanding ability of MEO to edge application demand and the management ability of edge computing, expand the arrangement and management function of MEO to naturally undertake the distributed application addressing task of site selection, and realize the overall scheduling of computing network.

[0075] Figure 3 An edge application addressing method based on computing power provided by the embodiment of the present disclosure is shown in the figure. Figure 3 As shown in the figure, the EASDF of 5GC configures the MEC system to which the distributed edge application belongs, when the EASDF receives the DNS request of edge application, the request is forwarded to the MEO in the MEC system corresponding to the domain name, and the terminal location information is carried through eDNS.

[0076] The MEO has the resource and application deployment view of each edge node in the system; the MEO queries the possible edge path and path delay information in the service area corresponding to the user location through network management NMS or intelligent network element NWDAF, calculates and evaluates the computing network resource in combination with the unified view information of application and resource possessed by the MEO (including the deployment situation of application, the resource situation of each edge node, etc.), determines the appropriate application instance or edge node, if the currently deployed application instance cannot guarantee the required service performance, the MEO can adjust the resource of service node or start a new service instance on the appropriate node, and then the IP address of the corresponding application instance and edge anchor point information (such as DNAI (Data Network Access Identifier)) are replied to the EASDF. The EASDF feeds back the IP address of the application instance to the UE through DNS response, and if the current session path of the UE is not the path corresponding to the edge anchor point, the user plane relocation can be triggered, such as inserting edge shunt point and edge anchor point, to establish the optimal path for the edge application to access the application instance.

[0077] The edge application addressing method based on computing power provided by the embodiment of the present disclosure enables the MEO to determine the optimal service instance by comprehensively considering the proximity of service and the resource advantage of business processing, guarantees the optimal performance of end-to-end, and the addressing of distributed edge application not only considers the proximity of service location, but also comprehensively considers the computing resource of service node, can provide better service experience for users, and guarantees the optimal state of the whole network resource advantage.

[0078] Figure 4 An edge application addressing method based on computing power provided by the embodiment of the present disclosure is shown in the figure, which includes the implementation process of EASDF forwarding DNS request to MEO to select appropriate edge application to provide application service for terminal user.

[0079] As a prerequisite, the EASDF pre-configures the MEO address of the MEC system corresponding to the edge application; the network management system NMS and / or the data analysis network element NWDAF continuously perform network data collection and connection performance analysis.

[0080] 1. In the process of establishing a session by the UE, the EASDF receives a DNS context generation request message forwarded by the UPF from the SMF, and then generates the DNS context of the session, including the UE IP address, SUPI, location information, pre-configured or acquired DNS processing rules, etc.

[0081] 2. The UE initiates a DNS request for a certain service through the session, and the request is sent to the EASDF;

[0082] 3. If the request matches the notification event of the DNS information processing (such as the domain name FQDN), the EASDF notifies the SMF of the received DNS request information, and the SMF replies after receiving it;

[0083] 4. If the SMF judges that the DNS message processing rule corresponding to the notification information needs to be updated, it requests the EASDF to update, and the EASDF replies after receiving it;

[0084] 5. The EASDF performs eDNS processing on the DNS request message, attaches the location information of the UE in the eDNS information, and forwards it to the corresponding MEO according to the domain name information in the DNS request;

[0085] 6. The MEO queries the NMS / NWDAF for the possible application access path and the performance of the path in the location of the UE;

[0086] 7. The MEO has a unified view of the resources and application deployment of the edge node; the MEO further combines the application deployment and resource situation of the edge node, the demand of the application and the queried information to determine the edge node or application instance providing the service;

[0087] 8. If the existing application instance cannot meet the performance requirements of the access service, the MEO starts a new application instance of the application on a suitable node, and the MEO can complete the instantiation of the application through other management network elements such as MEPM and VIM;

[0088] 9. The MEO returns the IP address of the determined instance and the corresponding edge network information (DNAI) of the corresponding edge node to the EASDF;

[0089] 10. If the EAS IP address or FQDN in the DNS response message matches the notification trigger condition, the EASDF sends a DNS message report to the SMF through a notification message (including EAS information, DNAI); then, the EASDF waits for the SMF instruction, that is, buffers the DNS response message without other operations; the SMF receives the notification and replies;

[0090] 11. If the SMF judges that the EAS IP address of the DNS response packet is an edge IP address, and the corresponding UE session anchor point is inconsistent with the DNAI, the ULCL / BP and local anchor L-PSA insertion operations are performed according to the DNAI, and the edge offloading user plane is established.

[0091] 12. The SMF updates the DNS information processing rule through a DNS context update request message, which includes a rule indicating that the EASDF sends the DNS response message buffered in step 10 to the UE; the EASDF replies to the DNS context update response message.

[0092] 13. The EASDF delivers the DNS response message to the UE.

[0093] 14. The UE accesses the corresponding application instance B through the established local offloading user plane according to the application instance IP (application instance B IP) in the DNS response message, thereby guaranteeing the experience of accessing the application.

[0094] In the embodiments of the present disclosure, the demand understanding ability of the MEO for edge applications and the management ability of edge computing are fully reused, the orchestration management function of the MEO is extended to naturally undertake the distributed application addressing task of the distribution point selection, and the overall scheduling of the algorithm network is realized; the network information subscription ability and the network analysis open ability of the NWDAF and the NMS are fully utilized, and the network and computing power are overall analyzed to realize the best matching with the end-to-end performance of the application, and better meet the high-capacity computing power demand of new business.
