Description

Technical Field

[0002] Edge computing is a distributed computing architecture that moves the computation of applications, data, and services from the central network node to logically located edge nodes. This allows large services that were originally handled by the central node to be broken down into smaller, more manageable parts and distributed to edge nodes. In edge computing applications, due to user location changes, the network side needs to modify the user path plane to ensure a good user experience, enabling edge applications to migrate and adjust accordingly. However, current application migration and adjustment processes consider relatively few factors, resulting in low accuracy. Summary of the Invention

Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0062] It should be understood that the steps described in the method embodiments of this disclosure may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.

[0063] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0064] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0065] In edge computing applications, due to user location changes, the network side needs to modify the user plane path and notify the application function (AF) network elements to ensure user service experience. In this way, the AF network elements can adjust their service migration strategies accordingly.

[0066] Currently, AF network elements select new application servers based on the data network access identifier (DNAI) and related configuration information sent by the network side. However, the lack of terminal participation in the selection process results in low accuracy of service migration between servers.

[0067] The background art has already provided a brief introduction to the currently common application configuration methods. In order to solve the above problems, this disclosure provides an application configuration method, apparatus, device and storage medium.

[0068] Figure 1 A flowchart of an application configuration method in an embodiment of this disclosure is shown. It should be noted that the above method is applied to AF network elements.

[0069] like Figure 1 As shown, the method may include:

[0070] S110, send a first request message to the core network element so that the core network element sends the first request message to the terminal. The first request message includes candidate edge cloud computing power information.

[0071] In some embodiments, the first request information may include an initial message AppRelocationInfo. For example, the initial message AppRelocationInfo may be an event NSmfEvenfExposureAppRelocationInfo from a session management function.

[0072] In some embodiments, the first request information may further include edge cloud computing power information, wherein the edge cloud computing power information is used to represent edge cloud computing power-related data. For example, the edge cloud computing power information may include the edge cloud's identifier, server resource status, supported application types, and network latency / bandwidth information.

[0073] In some embodiments, the edge cloud can be configured on the AF network element.

[0074] S120 receives the edge cloud selection strategy sent by the core network element.

[0075] In some embodiments, prior to S120, the terminal may send the edge cloud selection policy to the core network element.

[0076] In some embodiments, after the terminal receives the first request information, the first request information can be displayed to the user through a display screen so that the user can determine the edge cloud selection strategy.

[0077] In some embodiments, after the terminal receives the first request information, the terminal itself can generate an edge cloud selection strategy based on the first request information.

[0078] In some embodiments, core network elements include Session Management Function (SMF) elements and Access and Mobility Management Function (AMF) elements.

[0079] In some embodiments, sending a first request message to a core network element may include: the AF network element sending a first request message to the SMF network element.

[0080] In some embodiments, after the SMF network element receives the first request message, it can request the N1N2MessageTransfer service from the AMF network element. When the AMF network element constructs a NAS message PDU SessionModification Command and sends it to the terminal, it adds edge cloud computing power information to the enhanced policy control optimization ePCO field.

[0081] It should be noted that N1N2MessageTransfer is an important function in 5G networks. It allows network functions (such as SMF network elements) to transmit N1 or N2 information to terminals or RAN (Radio Access Network) through AMF network elements, or transmit both simultaneously.

[0082] In some embodiments, the NAS message can be a PDU Session Modification Command (PDU Session ModificationCommand).

[0083] In some embodiments, after receiving edge cloud computing power information, the terminal can determine an edge cloud selection strategy by combining terminal information. This terminal information may include application type, terminal status, and user habits.

[0084] In some embodiments, after determining the edge cloud selection strategy, the terminal can send the selected edge cloud selection strategy to the core network element through the ePCO field.

[0085] The application configuration method provided in the embodiments of this disclosure sends a first request information to the core network element, so that the core network element sends the first request information to the terminal, receives the edge cloud selection strategy sent by the core network element, and selects the edge cloud through the terminal, thereby improving the migration accuracy of the edge cloud currently carrying the service.

[0086] Figure 2 A flowchart of another application configuration method in an embodiment of this disclosure is shown. It should be noted that the above method is applied to AF network elements.

[0087] like Figure 2 As shown, the method may include:

[0088] S210, send a subscription user plane management request to the core network element.

[0089] In some embodiments, user plane management requests include requests where the user plane path changes when the user's location moves, and the core network element needs to send the information about the changed user plane path to the AF network element.

[0090] It should be noted that when a user moves, the user plane path, i.e. the path connecting to the network, will usually change in order to ensure the user's network quality.

[0091] S220, send a first request message to the core network element so that the core network element sends the first request message to the terminal. The first request message includes candidate edge cloud computing power information.

[0092] In some embodiments, prior to S220, the method may further include:

[0093] When the terminal location changes, it receives terminal location change information sent by the core network element.

[0094] In some embodiments, when the terminal location changes, the terminal's connection information to the core network changes, and the core network element determines that the terminal location has changed based on the changed information.

[0095] In some embodiments, the terminal location change information can be an Early Notification message.

[0096] In some embodiments, the terminal location change information may include DNAI information.

[0097] In some embodiments, the core network element sends terminal location change information after the terminal location begins to move but before it stops moving.

[0098] S230 receives edge cloud selection strategies sent by core network elements.

[0099] The application configuration method provided in the embodiments of this disclosure sends a first request information to the core network element, so that the core network element sends the first request information to the terminal, receives the edge cloud selection strategy sent by the core network element, and selects the edge cloud through the terminal, thereby improving the migration accuracy of the edge cloud currently carrying the service.

[0100] Figure 3 A flowchart of another application configuration method in an embodiment of this disclosure is shown. It should be noted that the above method is applied to AF network elements.

[0101] like Figure 3As shown, application configuration methods may include:

[0102] S310, send a first request information to the core network element so that the core network element sends the first request information to the terminal. The first request information includes candidate edge cloud computing power information.

[0103] S320 receives edge cloud selection strategies sent by core network elements.

[0104] S330 determines service migration applications based on edge cloud selection strategies, configuration information, and data network access identifier (DNAI).

[0105] In some embodiments, the configuration information may include application deployment information and a resource view, wherein the application deployment information may include information about the application deployment in the edge cloud. The resource view may include resource information such as computing resources and network resources for different applications.

[0106] In some embodiments, configuration information may be pre-stored on the AF network element.

[0107] The application configuration method provided in the embodiments of this disclosure sends a first request information to the core network element, so that the core network element sends the first request information to the terminal, receives the edge cloud selection strategy sent by the core network element, and selects the edge cloud through the terminal, thereby improving the migration accuracy of the edge cloud currently carrying the service.

[0108] Based on the same inventive concept, this disclosure also provides an application configuration method, as shown in the following embodiment. Since the principle by which this embodiment solves the problem is similar to that of the above method embodiments, the implementation of this embodiment can refer to the implementation of the above method embodiments, and repeated details will not be described again.

[0109] Figure 4 A flowchart of another application configuration method in this disclosure is shown. It should be noted that the above method is applied to core network elements.

[0110] S410 receives a first request message sent by the application function AF network element, the first request message including candidate edge cloud computing power information;

[0111] S420, the first request information is sent to the terminal so that the terminal can determine the edge cloud selection strategy based on the edge cloud computing power information;

[0112] S430 sends the edge cloud selection strategy to the AF network element.

[0113] In some embodiments, the core network element can send the edge cloud selection policy to the AF network element through a handover completion message.

[0114] In some embodiments, user path switching can be performed by core network elements, and edge application traffic will be diverted from PSA1 to PSA2 for routing. It should be noted that PSA (Path Switch Action) generally refers to a path switching action. It is an instruction or operation used to change the transmission path of data packets in the event of network failure or congestion. In network architecture, especially when complex routing and transmission strategies are involved, PSA can also be a critical component.

[0115] In some embodiments, the switching completion information may include a Late Notification message.

[0116] Specifically, in this embodiment of the disclosure, the core network element can be an SMF network element.

[0117] The application configuration method provided in the embodiments of this disclosure sends a first request information to the core network element, so that the core network element sends the first request information to the terminal, receives the edge cloud selection strategy sent by the core network element, and selects the edge cloud through the terminal, thereby improving the migration accuracy of the edge cloud currently carrying the service.

[0118] To provide a detailed description of this disclosure, an embodiment of this disclosure provides a schematic diagram of an application configuration architecture.

[0119] Figure 5 This illustration shows a schematic diagram of an application configuration architecture according to an embodiment of the present disclosure, such as... Figure 5 As shown.

[0120] The application configuration architecture may include: application configuration network elements, core network elements, terminals, base stations, traffic switching devices, and edge computing modules.

[0121] The application configuration network elements may include AF network elements. Core network elements may include NEF network elements, PCF network elements, SMF network elements, and AMF network elements. Traffic switching devices may include uplink classifiers (ULCL); edge computing modules may include APP and MEC servers.

[0122] It's important to note that ULCL is a feature introduced in 5G networks used to offload user uplink data packets. Specifically, ULCL allows the network side to offload IP data packets sent by terminals, that is, to route data packets from different services originating from the user to different paths. In 5G networks, this feature is part of the 5G Edge Computing (MEC) feature set.

[0123] The insertion or deletion of ULCLs is initiated by the SMF network element via the N4 interface and sent to the UPF network element that supports this function. The SMF can decide to insert ULCL UPFs according to its own configured rules when or after the PDU network element session is established, and multiple ULCL UPFs can be inserted for a single PDU session. For the user terminal, the insertion and deletion of ULCLs are transparent, that is, the UE is unaware of the existence of ULCL traffic splitting in the network.

[0124] The application configuration architecture provided in the embodiments of this disclosure sends a first request message to the core network element, so that the core network element sends the first request message to the terminal, receives the edge cloud selection strategy sent by the core network element, and selects the edge cloud through the terminal, thereby improving the migration accuracy of the edge cloud currently carrying the service.

[0125] To provide a detailed description of this disclosure, embodiments of this disclosure provide yet another application configuration method.

[0126] Figure 6 A signaling diagram of an application configuration method according to an embodiment of this disclosure is shown, such as... Figure 6 As shown, application configuration methods may include:

[0127] S601, AMF network element or SMF network element triggers user movement event.

[0128] In some embodiments, a user movement event may include an AF notification trigger met when the AF notification trigger condition is met.

[0129] S602, the AMF or SMF network element sends a user mobility notification to the NEF network element.

[0130] In some embodiments, user mobile notifications may include Nsmf_EventExposure_Notify(EarlyNotification).

[0131] S603, the NEF network element sends a terminal location movement pre-notification message to the Source AF network element.

[0132] In some embodiments, the terminal location movement pre-notification message may include Nnef_TrafficInfluence_Notify(Early Notification).

[0133] S604, the AMF network element or SMF network element sends a terminal location movement pre-notification message to the Source AF network element.

[0134] S605, the Source AF network element sends a terminal relocation message to the NEF network element.

[0135] In some embodiments, the terminal relocation message may include application relocation information guided by the Nnef_TrafficInfluence_AppRelocationInfo network open function.

[0136] S606, the NEF network element sends a terminal relocation message to the AMF network element or the SMF network element.

[0137] S607, the Source AF network element sends a terminal relocation message to the AMF or SMF network element.

[0138] In some embodiments, the terminal relocation message may include computing power information of the candidate edge cloud, such as the edge cloud identifier, server resource status, supported application types, network latency / bandwidth information, etc.

[0139] S608, UPF network element triggers terminal location change information.

[0140] In some embodiments, terminal location change information may include UPF addition, relocation or removal, insertion or redirection of user plane functions, and the edge cloud selection policy determined by the UE Selection Policy.

[0141] For example, the NAS message PDU Session Modification Command / ACK that the AMF needs to send to the UE can carry computing power information of candidate edge clouds, such as edge cloud identifier, server resource status, supported application types, network latency / bandwidth information, etc., as well as the edge cloud identifier selected by the terminal based on its own information.

[0142] S609, the AMF or SMF network element sends a notification message to the NEF network element after the terminal location has moved.

[0143] In some embodiments, the notification message after the terminal location moves may include Nsmf_EventExposure_Notify(Late Notification).

[0144] S610, the NEF network element sends a notification message to the Source AF network element after the terminal location has moved.

[0145] S611, the AMF network element or SMF network element sends a notification message about the terminal location moving to the Source AF network element.

[0146] In some embodiments, the notification message after the terminal location moves may include an edge cloud selection strategy.

[0147] For example, Nsmf_EventExposure_Notify(Late Notification) can notify the AF of the acquired terminal selection policy (edge ​​cloud identifier) ​​so that the AF can make decisions and make references for service migration. Since the UPF reselection and UE information acquisition in S608 are parallel steps (there will be a sequence of execution), SMF needs to do a logical enhancement to wait for the UPF reselection and UE information acquisition to be completed before sending the Late Notification.

[0148] S612, Source AF element confirms whether the AF example needs to be changed.

[0149] In some embodiments, confirming whether an AF instance needs to be changed may include checking whether an application functionality instance needs to be modified.

[0150] S613, the Source AF network element sends a function migration message to the NEF network element.

[0151] In some embodiments, the feature migration message may include Nnef_TrafficInfluence_AppRelocationInfo.

[0152] S614, the NEF network element sends a function migration message to the AMF network element or the SMF network element.

[0153] S615, the Source AF network element sends a function migration message to the AMF network element or SMF network element.

[0154] The application configuration method provided in the embodiments of this disclosure obtains the computing power information of the terminal, and configures the application based on the computing power information of the terminal, pre-configured information and data network access identifier (DNAI). In the process of configuring the application, the computing power information of the terminal is taken into consideration, making the application configuration more accurate.

[0155] Figure 7 A flowchart of an application configuration method in an embodiment of this disclosure is shown. It should be noted that the method in this embodiment is applied to core network elements.

[0156] like Figure 7 As shown, the method may include:

[0157] S710 receives the first request information sent by the application function AF network element. The first request information includes candidate edge cloud computing power information.

[0158] S720 sends the first request information to the terminal so that the terminal can determine the edge cloud selection strategy based on the edge cloud computing power information.

[0159] When the terminal location changes, the S730 sends a terminal location change information to the AF network element.

[0160] S740 sends the edge cloud selection strategy to the AF network element.
