[0107] In some embodiments, obtaining data, information, etc. may comply with the laws and regulations of the country where the data is obtained.

[0108] In some embodiments, data, information, etc. may be obtained with the user's consent.

[0109] The 5G system supports the function of tracking and reporting UE mobility events. The Access and Mobility Management Function (AMF) network element provides UE mobility-related event reports to the Network Function (NF) that has been authorized to subscribe to the UE mobility event reporting service. If the NF service consumer subscribes to the UE mobility event notification service provided by the AMF for reporting UE mobility events in the area of ​​interest, the AMF will consider the CM state of the UE and use the NG-RAN procedure to track the location of the UE to determine the presence of the UE in the area of ​​interest. After detecting a change in the presence of the UE in the area of ​​interest, the AMF notifies the subscribed NF service consumer of the UE presence and the new UE location in the area of ​​interest. As shown in the data storage architecture diagram of Figure 1A, the 5G system architecture allows the unified data management function (UDM) network element, policy control function (PCF) and network exposure function (NEF) to store data in the unified data repository function (UDR), including subscription data and policy data of UDM and PCF, structured data for exposure, and application data (including packet flow description for application detection and third-party application function (AF) request information for multiple UEs).

[0110] Currently, NWDAF provides an external AI function to the network, but it cannot analyze network status, UE mobility, node information, and other factors to better utilize network resources. Computing services provided by the network are still executed only within the core network, without utilizing the computing and storage resources of the UE / gNB. There is no solution for computing service migration.

[0111] As UE performance continues to improve, they will possess powerful computing capabilities. If the capabilities of user terminals can be fully utilized, the computing power and service capabilities of the communication network will be greatly enhanced. Furthermore, the computing power of base stations and third-party AFs can also be leveraged. Therefore, collaborative computing between the UE / gNB / AF and the network is foreseeable. However, in practice, due to factors such as tidal fluctuations, user mobility, and failures, services often require timely adjustments. Failure to do so can lead to load imbalances across computing nodes in both time and space, resulting in wasted resources and reduced service quality. Therefore, it is necessary to monitor and predict network status, UE mobility, and node information, dynamically redeploy and migrate computing services, and schedule computing tasks to appropriate nodes to improve service quality and computing capacity utilization efficiency.

[0112] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium, which can improve the computing capability of the network by applying specific computing functions. The network can monitor and predict network status, UE mobility and node information, dynamically redeploy and migrate computing services, and schedule computing tasks to appropriate computing nodes to improve business service quality.

[0113] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G, etc.).

Furthermore, multiple systems may be combined (for example, LTE or LTE EA combined with 5G) for application.

[0175] Figure 2 is a schematic diagram of an interaction method provided by an embodiment of the present disclosure. As shown in Figure 2, an embodiment of the present disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1B. The communication system includes a first terminal and at least one second terminal. The interaction method may include the following steps:

[0176] Step 2101: The first network element analyzes the network status and / or terminal mobility and triggers computing service migration.

[0177] In some embodiments, the first network element subscribes to a reporting service for migration events from other network elements before analyzing the network status and / or terminal mobility. In other words, the first network element needs to call a reporting service for network status and / or terminal mobility from other network elements.

[0178] In some embodiments, the first network element periodically or in response to an unexpected situation such as a fault, analyzes changes in network status and / or terminal mobility and triggers computing service migration. The fault may be the failure of the original computing node to successfully complete a computing task, the failure of the original computing node to successfully report a computing result, or a network disconnection, etc., which are not limited in this disclosure.

[0179] In some embodiments, after analyzing the network status and / or terminal mobility, the first network element triggers computing service migration based on the analysis result, wherein the analysis result is used to indicate whether the first condition is met.

[0180] In some embodiments, terminal mobility is the change in terminal mobility reported by the AMF, and the network status is reported by the computing node. For example, the network element has the ability to perceive internally and can monitor the status within the network, such as sensing connectivity or the computing power of the node. The network element reports the network status when a network failure occurs.

[0181] In some embodiments, the first network element can internally sense the load of the computing node, whether the computing node successfully executes the computing task, and whether the computing node successfully reports the execution result of the computing task.

[0182] For example, the CF network element analyzes the network status and finds that the network status does not meet the execution condition of the computing service, or the CF network element analyzes the position of the first computing node and finds that the position of the first computing node is out of the interest domain of the computing service.

[0183] For example, the CF network element analyzes the perceived load of the computing node and the execution status of the computing node, and obtains that the load of the first computing node does not meet the execution conditions of the computing task, or the first computing node fails to successfully execute the computing task, or the first computing node fails to successfully report the execution result of the computing task.

[0184] In some embodiments, the first network element triggers computing service migration when the analysis result meets the first condition.

[0185] In some embodiments, computing service migration is used to migrate computing tasks deployed on a first computing node to a second computing node.

[0186] In some embodiments, the first condition includes at least one of the following: the network status does not meet the execution conditions of the computing service; due to terminal mobility, the location of the first computing node is out of the domain of interest of the computing service; the load of the first computing node does not meet the execution conditions of the computing task; the first computing node fails to successfully execute the computing task; the first computing node fails to successfully report the execution results of the computing task.

[0187] For example, when the network status does not meet the execution conditions of the computing service, the CF network element triggers the computing service migration and migrates the computing task on the first computing node to the second computing node.

[0188] In the above embodiment, the first network element analyzes and determines the acquired network status and / or terminal mobility. If the analysis result satisfies the first condition, the computing service migration is triggered, migrating the computing task deployed on the first computing node to the second computing node, thereby improving the execution efficiency of the computing service.

[0189] Step 2102: The first network element receives computing power information of the computing node sent by the second network element.

[0190] In some embodiments, the second network element may be a DSF.

[0191] In some embodiments, the first network element may retrieve or query computing power information of the computing node from the second network element.

[0192] In some embodiments, the computing power information of the computing node sent by the second network element may be computing power information of at least one computing node in a first area, where the first area is the area to which the terminal initiating the computing service belongs.

[0193] In some embodiments, the computing node in the first area may be a first computing node and a second computing node, wherein the first computing node is the computing node before computing service migration and the second computing node is the computing node after computing service migration.

[0194] In some embodiments, at least one computing node sends computing power information to the second network element, and the second network element sends the computing power information of the computing node to the first network element.

[0195] In some embodiments, the computing node may be a terminal, a gNB, a third-party AF, a NF, etc., which is not limited in this disclosure.

[0196] For example, the gNB sends the computing power information to the DSF, and the DSF sends the computing power information of the gNB to the CF.

[0197] For example, the third-party AF sends computing power information to the DSF, and the DSF sends the computing power information of the third-party AF to the CF.

[0198] In the above embodiment, the computing power information of the computing node is used by the first network element to determine the target node for computing task migration among the candidate computing nodes, that is, the second computing node.

[0199] Step 2103: The first network element determines a candidate computing node.

[0200] In some embodiments, the first network element determines a candidate computing node from at least one computing node. The candidate computing node meets the requirements of the computing service. For example, the computing power information of the candidate computing node registered in the second network element substantially meets the requirements of the computing service. It should be understood that the candidate computing node can be the node that ultimately executes the computing service, or it can be a node that does not participate in executing the computing service due to factors such as insufficient actual processing power or real-time computing power.

[0201] For example, CF selects a computing node that meets the service requirements.

[0202] In some embodiments, the first network element determines the candidate computing node based on computing power information sent by the second network element.

[0203] In some embodiments, the demand for computing services may be a network status that satisfies the computing task, or a load on a computing node that satisfies the execution conditions of the computing task, or a computing node that has the resources to execute the computing task.

[0204] In some embodiments, the candidate computing nodes may include the first computing node and / or the second computing node.

[0205] Step 2104: The first network element sends a first message to the third network element.

[0206] In some embodiments, the third network element may be a DCF.

[0207] In some embodiments, the first message is used to request the third network element to obtain real-time capability information of the candidate computing node.

[0208] For example, the CF sends a capability reporting request to the DCF.

[0209] In some embodiments, the first network element requests the third network element to obtain the real-time capability information of the candidate computing node in order to determine the computing node to receive the computing service migration (ie, the computing node that can currently execute the computing service) based on the real-time capability information of the candidate computing node.

[0210] Step 2105: The third network element sends a first message to the candidate computing node.

[0211] In some embodiments, after receiving the first message, the third network element forwards the first message to the candidate computing node in order to instruct the candidate computing node to report the real-time capability information to the third network element.

[0212] In some embodiments, a computing node may be any one of a terminal, a gNB, a third-party AF, and a core network NF. The computing node may be at least one of the candidate computing node, the first computing node, and the second computing node mentioned in this disclosure. Optionally, the type and / or number of the first computing node and the second computing node may be the same, partially the same, or different. In one example, the first computing node is a terminal and a third-party AF, and the second computing node is a terminal and a gNB, but this disclosure is not limited to this.

[0213] For example, the DCF sends the first message to a computing power node, which may be one or more computing power nodes, including a terminal, a gNB, a third-party AF, a core network NF, etc. The terminal serving as the computing power node may be a terminal that initiates a computing service or another terminal.

[0214] In the present disclosure, a computing node (computing power node) may include a first computing node (an original computing node that executes the computing service) and a second computing node (a migrated computing node that can execute the computing service).

[0215] In some embodiments, the third network element sends a first message to the first computing node, instructing the first computing node to report real-time capability information. In some examples, this step can be omitted, for example, if the network determines that the original computing node is no longer suitable for performing the computing service, the original computing node may not report its real-time capability information.

[0216] In some embodiments, the third network element sends a first message to the second computing node, instructing the second computing node to report real-time capability information.

[0217] Step 2106: The candidate computing node sends real-time capability information to the third network element.

[0218] In some embodiments, after receiving the first message, the candidate computing node sends its own real-time capability information to the third network element.

[0219] For example, the computing power node reports computing power information to the DCF.

[0220] In some embodiments, the candidate computing nodes include computing nodes before computing service migration and computing nodes after computing service migration.

[0221] In some embodiments, the first computing node and the second computing node send the real-time capability information to the third network element.

[0222] Step 2107: The third network element sends the real-time capability information of the candidate computing node to the first network element.

[0223] In some embodiments, after receiving the real-time capability information sent by the candidate computing node, the third network element may process and / or cleanse the real-time capability information of the candidate computing node and send the processed and / or cleansed real-time capability information to the first network element. Optionally, after receiving the real-time capability information of the candidate computing node, the third network element may not process it and directly send the real-time capability information to the first network element. For example, the format of the real-time capability information of each candidate computing node is the same or compatible.

[0224] For example, after DCF receives the real-time capability information of the old computing power node, the real-time capability information of the new computing power node, and the real-time capability information of other computing power nodes, it processes and / or cleans the real-time capability information and sends the processed and / or cleaned real-time capability information to CF.

[0225] In some embodiments, the processed and / or cleaned real-time capability information is used by the first network element to generate a service migration method.

[0226] Step 2108: The first network element generates a service migration method.

[0227] In some embodiments, the first network element generates a service migration method based on the real-time capability information and / or the first condition.

[0228] For example, the CF network element generates a service migration method according to the received real-time capability information and / or analysis results.

[0229] In some embodiments, the service migration method may be a method for migrating a computing task from an original computing node (a first computing node) to a new computing node (a second computing node): for example, the original computing node may directly migrate the computing task to the new computing node; for example, the original computing node may first send the computing task to an intermediate node, which then sends the task to the new computing node. The intermediate node may be a computing node or a network element function (e.g., AMF).

[0230] In some embodiments, the service migration method may also be a specific computing method, such as which nodes execute the computing service, how to execute the computing service, etc.

[0231] Step 2109: The first network element sends a second message to the second computing node.

[0232] In some embodiments, before sending the second message, the first network element further determines the second computing node from the candidate computing nodes.

[0233] In some embodiments, the first network element determines a second computing node from the candidate computing nodes based on the real-time capability information, and the second computing node is used to receive computing tasks and / or data sent by the first computing node.

[0234] In some embodiments, the first network element sends a second message to the second computing node, where the second message is used to instruct the second computing node to reserve computing resources.

[0235] In some embodiments, the computing resources are used for computing service migration, wherein the computing service migration is used to migrate a computing task deployed on a first computing node to a second computing node.

[0236] In some embodiments, the computing resources reserved by the second computing node are used to execute the computing tasks migrated by the first computing node.

[0237] Step 2110: The second computing node sends a third message to the first network element.

[0238] In some embodiments, the third message is used to feedback the reserved computing resources.

[0239] In some embodiments, after receiving the instruction to reserve computing resources sent by the first network element, the second computing node performs a resource reservation operation and provides feedback to the first network element.

[0240] For example, after receiving the instruction, the new computing node reserves computing resources and then feeds back to the CF the reserved computing resources.

[0241] In some examples, the third message may explicitly provide feedback on reserved computing resources. For example, if a bit in the third message is set to 1, it indicates that the second computing node has reserved computing resources for the computing service, while a bit in the third message is set to 0, indicating that no computing resources have been reserved. The third message may also implicitly provide feedback on reserved resources. For example, if the second computing node sends the third message, it indicates that computing resources have been reserved for the computing service, while if the third message is left blank, it indicates that no computing resources have been reserved.

[0242] In some embodiments, after receiving the indication of reserved computing resources sent by the first network element, the second computing node is unable to reserve computing resources and does not provide feedback to the first network element. Then the first network element needs to re-determine the second computing node among the candidate computing nodes to execute the indication of reserved computing resources and receive the computing tasks migrated by the first computing node.

[0243] Step 2111: The first network element sends a fourth message to the first computing node.

[0244] In some embodiments, the fourth message is used to request computing service migration and / or request the first computing node to release computing resources.

[0245] For example, the CF sends instruction information to the old computing node, instructing the old computing node to perform computing service migration and computing resource release. The old computing node no longer performs computing tasks, but migrates the computing tasks to the new computing node.

[0246] Step 2112: The first computing node performs computing service migration and / or releases computing resources.

[0247] In some embodiments, in response to the fourth message, the first computing node performs computing service migration and / or releases computing resources.

[0248] In some embodiments, the first computing node may perform computing service migration according to a service migration method generated by the first network element.

[0249] In some embodiments, the first computing node performing computing service migration may be sending the computing task to the second computing node.

[0250] For example, the old computing node sends the computing task directly to the new computing node.

[0251] In some embodiments, the first computing node performing computing service migration may be sending the computing task to a fourth network element, and the fourth network element is used to send the computing task to the second computing node.

[0252] For example, the old computing node sends the computing task to the AMF, and the AMF sends the computing task to the new computing node.

[0253] Step 2113: The first computing node sends a fifth message to the first network element.

[0254] In some embodiments, the fifth message is used to feedback computing service migration and / or feedback that the first computing node has released computing resources.

[0255] For example, after receiving the instruction information of computing service migration and computing resource release, the old computing node feeds back the computing service migration result and the computing resource release result to the CF.
