[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0058] In edge computing system applications, existing scenarios mostly focus on fixed MEC systems and services deployed in fixed environments. With the development of industries such as vehicle-to-the-world information exchange, the demand for service switching and invocation between MEC systems is gradually increasing, and collaboration technologies between MEC systems are also gaining importance. However, current MEC system relocation solutions involve relocating the user device to another MEC system before applying context data and application instances, which can lead to insufficient resources in the target MEC system and subsequent service interruptions. Therefore, this invention provides a technical solution that pre-deploys other MEC systems based on changes in the user device's movement speed and location information. This reduces the latency of switching between multiple edge computing systems due to location changes, achieving continuous and seamless switching of MEC system services. It prevents resource shortages caused by neighboring edge computing systems during edge computing system switching, or slow context data transmission or application instance establishment, thus avoiding further service interruptions and improving service quality and user experience.

[0059] Figure 1 This is one of the flowcharts illustrating the user equipment relocation method provided by the present invention, applied to an initial MEC system, including:

[0060] If the first moving speed is greater than or equal to the preset speed, and / or if the difference between the first location information and the first preset range is less than the first preset difference, deploy resource messages related to the user equipment and add a relocation request identifier to the user equipment to generate a relocation request for the user equipment.

[0061] Extract all target MEC systems from all MEC systems within the scope of the initial multi-access edge computing MEC system, and send the relocation request and resource message to all target MEC systems;

[0062] If the difference between the second location information and the second preset range is less than the second preset difference, the edge computing application instance and context data related to the user equipment are sent to all target MEC systems.

[0063] If the service signal strength between any target MEC system and the user equipment is greater than the service signal strength between the initial MEC system and the user equipment, the target MEC system is determined to be the final MEC system.

[0064] The first moving speed and the first location information are obtained by the user equipment during the initial MEC system service.

[0065] The second location information is obtained after the initial MEC system sends the relocation request and resource message to all target MEC systems;

[0066] The resource message refers to the memory required for edge computing application instances and context data;

[0067] The target MEC system is a MEC system in a preset available state.

[0068] In step 101, the first moving speed and the first location information are obtained by the user equipment under the service of the initial MEC system. That is, in this invention, the MEC system that provides services to the user equipment is designated as the initial MEC system, the execution entity is the initial MEC system, and the initial MEC system obtains the real-time moving speed and location information of the user equipment, namely the first moving speed and the first location information.

[0069] In another optional embodiment, the execution entity can also be the application relocation module in the initial MEC system. In such an embodiment, the application relocation method based on edge computing described in this invention is implemented by adding an application relocation module within the edge computing system. Specifically, the application relocation module is mainly responsible for identifying the relocation requirements of user devices, sending and obtaining the distance to the target MEC system, sending resource reservation information, application instance deployment messages, context data, and other operations to the target MEC system.

[0070] The preset speed is a preset value for the application relocation requirement, which can be customized according to the requirements and service resources. The first preset range is the maximum boundary of the service quality assurance range. The first preset difference can be customized according to the requirements and service resources. That is, when the user equipment is a certain distance away from the maximum boundary of the service quality assurance range, resource messages related to the user equipment are deployed, and a relocation requirement identifier is added to the user equipment to generate the relocation requirement of the user equipment.

[0071] In an optional embodiment, if the first moving speed is greater than or equal to a preset speed, a resource message related to the user equipment is deployed, and a relocation request identifier is added to the user equipment to generate a relocation request for the user equipment.

[0072] In another optional embodiment, if the difference between the first location information and the first preset range is less than the first preset difference, a resource message related to the user equipment is deployed, and a relocation request identifier is added to the user equipment to generate a relocation request for the user equipment.

[0073] In another alternative embodiment, if the first moving speed is greater than or equal to a preset speed, and if the difference between the first location information and the first preset range is less than a first preset difference, resource messages related to the user equipment are deployed, and a relocation request identifier is added to the user equipment to generate a relocation request for the user equipment.

[0074] Optionally, resource messages related to the user device are deployed. These resource messages are the memory required for edge computing application instances and context data, i.e., information representing the memory size that needs to be deployed. Adding a relocation requirement identifier to the user device is to generate a relocation requirement for the user device, at which point the user device may need to switch to the MEC system.

[0075] In step 102, all target MEC systems are extracted from all MEC systems within the scope of the initial multi-access edge computing (MEC) system. The relocation request and resource message are then sent to all target MEC systems. These target MEC systems are those in a preset available state; not all MEC systems within the scope of the initial MEC system are available. Some MEC systems may be unable to accept or respond to the handover service due to equipment failure, high load, or incompatibility, thus becoming unavailable. In such cases, all target MEC systems need to be extracted from all MEC systems, allowing the initial MEC system to send the relocation request and resource message determined in step 101 to all target MEC systems. This invention, upon receiving the relocation request and resource message from the user equipment of the initial MEC system, reserves the required memory and computing resources for seamless handover of subsequent application relocation services.

[0076] In step 103, if the difference between the second location information and the second preset range is less than the second preset difference, the edge computing application instance and context data related to the user equipment are sent to all target MEC systems. The second location information is obtained after the initial MEC system sends the relocation request and resource message to all target MEC systems. Optionally, if the second preset difference is less than the first preset difference, that is, the user equipment is closer to the boundary of the quality of service assurance range, it is possible that the user equipment is already at the boundary of the quality of service assurance range, or is within the quality of service assurance range of other target MEC systems. In this case, the edge computing application instance and context data related to the user equipment can be sent to all target MEC systems.

[0077] Compared to step 102, where the relocation request and resource message with a smaller data volume are sent to other target MEC systems to reserve relevant memory locations, step 103 directly sends the specific content, namely the edge computing application instance and context data related to the user equipment, to each target MEC system to correspond with the reserved memory locations. After receiving the edge computing application instance and context data related to the user equipment, all target MEC systems use the reserved resources to establish the application instance and context data, preparing for the user equipment to enter the service quality assurance range boundary.

[0078] In step 104, if the service signal strength between any target MEC system and the user equipment is greater than the service signal strength between the initial MEC system and the user equipment, the target MEC system is determined to be the final MEC system. This invention monitors the service quality of the user equipment for all target MEC systems in real time. After the service quality of any target MEC system obtained by the user equipment is better than that of the initial MEC system, a service request is initiated to the target MEC system, and the target MEC system begins to provide services, becoming a new source MEC, that is, the final MEC system.

[0079] Optionally, after determining that the target MEC system is the final MEC system, the method further includes:

[0080] Send the first instruction to all unselected target MEC systems;

[0081] The first instruction is used to instruct all unselected target MEC systems to release the edge computing application instances and context data associated with the user equipment;

[0082] The unselected target MEC systems refer to all target MEC systems other than the final MEC system.

[0083] Since the edge computing application instances and context data related to the user equipment were sent to all target MEC systems in step 103, a cache of these user equipment-related edge computing application instances and context data exists in all target MEC systems. If this cache is not cleared in time, it may lead to insufficient system resources, slow operation, or freezing in other target MEC systems. Therefore, after determining the final MEC system, it is necessary to release the user equipment-related edge computing application instances and context data in all unselected target MEC systems in a timely manner. That is, the initial MEC system sends a first instruction to all unselected target MEC systems, and all unselected target MEC systems release the user equipment-related edge computing application instances and context data after receiving the first instruction.

[0084] The application relocation method provided by this invention includes resource reservation for the target MEC system, pre-establishment of edge computing application instances, transmission of context data, and release of reserved expired resources. It can achieve seamless switching of MEC systems without excessive redevelopment or modification of existing MEC systems, further realizing the interoperability of ubiquitous edge computing power, improving service continuity, and enhancing user experience and service quality.

[0085] This invention provides a user equipment relocation method, apparatus, device, and medium. When the user equipment's movement speed and location information change, requiring switching between multiple edge computing systems, the method allows the target MEC system to prepare for the switch in advance based on the user equipment's different location states and preset judgment conditions. Specifically, before the user equipment moves into the target MEC system's range, resources are reserved in advance, application instances are deployed, and context data is transmitted to ensure that the user equipment has the ability to directly provide services when it enters the final MEC system's range. This meets the requirement for MEC service continuity during user mobility and improves service quality and user experience.

[0086] Figure 2 This is a flowchart illustrating the process of extracting all target MEC systems provided by the present invention. The step of extracting all target MEC systems from all MEC systems within the scope of the initial multi-access edge computing MEC system includes:

[0087] After identifying all MEC systems within the third preset range that have the same service capabilities as the initial MEC system, a first request instruction is sent to all MEC systems.

[0088] All target MEC systems are identified based on the first feedback instruction;

[0089] The first feedback instruction is a feedback instruction issued by the MEC system in a preset available state after receiving the first request instruction.

[0090] In step 1021, firstly, all MEC systems with the same service capabilities as the initial MEC system within a third preset range are identified. The third preset range can be customized according to needs and service resources. Then, a first request instruction is sent to all MEC systems. The first request instruction is used to instruct all MEC systems to choose whether to generate a first feedback instruction based on their own operating status.

[0091] In step 1022, all target MEC systems are determined according to the first feedback instruction. The first feedback instruction is a feedback instruction issued by the MEC system in the preset available state after receiving the first request instruction. That is, only the MEC system in the available state will send the first feedback instruction to the initial MEC system. The initial MEC system then receives the first feedback instruction and determines all target MEC systems according to the first feedback instruction.

[0092] Figure 3 This is the second flowchart of the user equipment relocation method provided by the present invention, which is applied to all target MEC systems. The execution entity is all target MEC systems, including:

[0093] After receiving a relocation request and resource message, each target MEC system reserves reserved memory that matches the resource message of the user equipment.

[0094] After receiving the edge computing application instance and context data related to the user equipment, each target MEC system receives the edge computing application instance and context data related to the user equipment according to the reserved memory.

[0095] If any target MEC system receives the second instruction, the final MEC system is determined from all target MEC systems.

[0096] The second instruction is used to instruct the user equipment to switch its services in the initial MEC system to the user's services in the final MEC system.

[0097] In step 201, the initial MEC system sends relocation requests and resource messages to all target MEC systems so that each target MEC system can receive the relocation requests and resource messages. After receiving the relocation requests and resource messages, each target MEC system starts reservation processing according to the relocation requests, determines the user equipment, and reserves reserved memory that matches the resource messages of the user equipment according to the resource messages.

[0098] In step 202, the initial MEC system sends the user equipment-related edge computing application instance and context data to all target MEC systems, so that each target MEC system receives the user equipment-related edge computing application instance and context data. After receiving the user equipment-related edge computing application instance and context data, since reserved memory matching the resource message of the user equipment has been reserved in step 201, it can receive the user equipment-related edge computing application instance and context data according to the reserved memory.

[0099] In step 203, according to step 104, if the service signal strength between any target MEC system and the user equipment is greater than the service signal strength between the initial MEC system and the user equipment, the target MEC system is determined to be the final MEC system, and a second instruction is generated. The initial MEC system sends the second instruction to the final MEC system among all target MEC systems. On the target MEC system side, that is, when any target MEC system receives the second instruction, the final MEC system is determined from all target MEC systems. The second instruction is used to instruct the user equipment to switch the service in the initial MEC system to the user's service in the final MEC system.

[0100] Optionally, after determining the final MEC system from all target MEC systems, the process also includes:

[0101] Upon receiving the first instruction, the edge computing application instance and context data associated with the user equipment are released.

[0102] The first instruction is used to instruct all unselected target MECs to release the edge computing application instances and context data associated with the user equipment;

[0103] The unselected target MEC systems refer to all target MEC systems other than the final MEC system.

[0104] In such an embodiment, after the final MEC system is determined, it is necessary to promptly release the edge computing application instances and context data related to the user equipment in all unselected target MEC systems. That is, the initial MEC system sends a first instruction to all unselected target MEC systems, and all unselected target MEC systems release the edge computing application instances and context data related to the user equipment after receiving the first instruction.

[0105] Optionally, after determining the final MEC system from all target MEC systems, the process also includes:

[0106] The second moving speed and third location information of the user equipment in the final MEC system are obtained until the handover of the user equipment in any MEC system is completed.

[0107] Those skilled in the art will understand that, after determining the final MEC system from all target MEC systems, the final MEC system is used as the execution entity to obtain the second moving speed and third location information of the user equipment providing services within the final MEC system. Then, if the second moving speed is greater than or equal to a preset speed, and / or if the difference between the third location information and a first preset range is less than a first preset difference, resource messages related to the user equipment are deployed, and a relocation request identifier is added to the user equipment to generate a relocation request for the user equipment. All target MEC systems related to the final MEC system are extracted from all MEC systems within the scope of the final MEC system, and the relocation request and resource messages are sent to the target MEC system with the most... The target MEC system related to the final MEC system; if the difference between the fourth location information and the second preset range is less than the second preset difference, the edge computing application instance and context data related to the user equipment are sent to all target MEC systems. The fourth location information is obtained after the final MEC system sends the relocation request and resource message to all target MEC systems. If the service signal strength between any target MEC system related to the final MEC system and the user equipment is greater than the service signal strength between the final MEC system and the user equipment, the target MEC system is determined to be the MEC system to be switched. The user equipment's movement speed and location information are obtained in the MEC system to be switched until the user equipment is switched to any MEC system.

[0108] Figure 4This is one of the structural schematic diagrams of the user equipment relocation device provided by the present invention. The present invention provides a user equipment relocation device, the execution subject of which is an initial MEC system, including a deployment module 11: used to deploy resource messages related to the user equipment and add a relocation requirement identifier to the user equipment when the first moving speed is greater than or equal to a preset speed, and / or when the difference between the first location information and the first preset range is less than the first preset difference, so as to generate the relocation requirement of the user equipment. The working principle of the deployment module 11 can be referred to the aforementioned step 101, and will not be repeated here.

[0109] The user equipment relocation device further includes an extraction module 12: used to extract all target MEC systems from all MEC systems within the scope of the initial multi-access edge computing MEC system, so as to send the relocation request and resource message to all target MEC systems. The working principle of the extraction module 12 can be referred to the aforementioned step 102, and will not be repeated here.

[0110] The user equipment relocation device further includes a sending module 13: when the difference between the second location information and the second preset range is less than the second preset difference, it sends the edge computing application instance and context data related to the user equipment to all target MEC systems. The working principle of the sending module 13 can be referred to the aforementioned step 103, and will not be repeated here.

[0111] The user equipment relocation device further includes a first determining module 14: used to determine the target MEC system as the final MEC system when the service signal strength between any target MEC system and the user equipment is greater than the service signal strength between the initial MEC system and the user equipment. The working principle of the first determining module 14 can be referred to the aforementioned step 104, and will not be repeated here.

[0112] The first moving speed and the first location information are obtained by the user equipment during the initial MEC system service.

[0113] The second location information is obtained after the initial MEC system sends the relocation request and resource message to all target MEC systems;

[0114] The resource message refers to the memory required for edge computing application instances and context data;

[0115] The target MEC system is a MEC system in a preset available state.

[0116] This invention provides a user equipment relocation method, apparatus, device, and medium. When the user equipment's movement speed and location information change, requiring switching between multiple edge computing systems, the method allows the target MEC system to prepare for the switch in advance based on the user equipment's different location states and preset judgment conditions. Specifically, before the user equipment moves into the target MEC system's range, resources are reserved in advance, application instances are deployed, and context data is transmitted to ensure that the user equipment has the ability to directly provide services when it enters the final MEC system's range. This meets the requirement for MEC service continuity during user mobility and improves service quality and user experience.

[0118] The user equipment relocation device further includes a receiving module 22: after each target MEC system receives the edge computing application instance and context data related to the user equipment, it receives the edge computing application instance and context data related to the user equipment according to the reserved memory.
