[0082] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar.

[0083] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0084] First, some of the terms used in the embodiments of this disclosure will be explained:

[0085] 5G (Fifth Generation Mobile Communication Technology)

[0086] 6th Generation Mobile Communication Technology (6G)

[0087] Application Function (AF)

[0088] Artificial Intelligence (AI)

[0089] Core Network (CN)

[0090] (Radio Access Network, (RAN))

[0091] Network Function (NF)

[0092] Quality of Service (QoS)

[0093] 5G networks are centralized and interconnected. The movement of terminals (or user equipment, UE) leads to changes in the connected base stations and network nodes (CN and NF), which in turn affects the consistency of terminal services. Furthermore, with the advent of 6G, 6G supports more and more capabilities, and the capabilities of different network nodes vary. Different network nodes provide different service states under different conditions, which will affect the continuity of terminal services.

[0094] To address the aforementioned issues, this disclosure provides a service processing method, apparatus, terminal, and storage medium. When a first node determines that it can no longer process a first service of the terminal, it sends a first instruction message to the terminal; the terminal then migrates its service to a second node based on the first instruction message. The solution provided by this disclosure ensures the continuity of the terminal's services and improves the user experience.

[0095] In some embodiments, the 6G network architecture needs to introduce a central network and distributed subnets. Please refer to Figure 1, which is a schematic diagram of the 6G network architecture provided in this embodiment. As shown in Figure 1, the architecture includes a central network and distributed subnets.

[0096] In some embodiments, a "distributed subnet" can also refer to localized services provided by a Public Land Mobile Network (PLMN), and the name of a distributed subnet can also be "localized services".

[0097] It should be noted that the name of the distributed subnet is not limited in this embodiment. For example, in some embodiments, the distributed subnet may also be referred to as "subnet," "distributed network," "distributed node," "distributed network node," etc., which are interchangeable. Furthermore, the terms "central" and "distributed" in this embodiment are relative and not strictly physical locations. The central network meets the needs of wide-area coverage and universal new service requirements such as intelligence and sensing; the distributed subnet mainly meets specific needs in various scenarios, including connectivity, intelligence, and sensing, such as localized access and customized subnets for enterprises (2B), satellite network access, and personalized subnets for personal services. The 6G network architecture is constructed through flexible, on-demand, and intelligent network design, presenting the connection relationships and network forms between various networks. The central network has relatively complete functions, and the distributed subnet follows the principle of simplicity. Based on the cooperation between the wireless access and the core network, and the interconnection between the central subnet and the distributed subnet, the 6G network evolves from two-dimensional to full-space three-dimensional coverage through high- and low-frequency cooperative access and air-space-ground integrated access networking. This meets the needs of ubiquitous 6G connectivity scenarios and provides 6G with green and sustainable ubiquitous access and co-construction and sharing infrastructure that is compatible with various industry ecosystems.

[0098] In this embodiment of the disclosure, the 6G network has the following capabilities:

[0099] 1. Connectivity: A network uses physical links to connect isolated workstations or hosts, forming data links to achieve resource sharing and communication. Communication is the exchange and transmission of information between people through some medium. Network communication connects isolated devices through a network, enabling communication between people, between people and computers, and between computers through information exchange.

[0100] 2. Sensing Capability: The 6G network adds wireless sensing capability, which is used to receive wireless sensing service requests, perform wireless sensing control, process wireless sensing service data, and open up wireless sensing results to the outside world. The wireless sensing function supports selecting terminals with wireless sensing capability as wireless sensing nodes, obtaining wireless sensing data provided by the terminals, and opening up the wireless sensing results to the terminals.

[0101] Sensing capabilities will be a crucial aspect of mobile communication systems in the 6G era, in addition to their basic communication capabilities. 6G base stations will need to monitor the status of targets within their coverage area, and also possess real-time measurement and sensing capabilities for weather, natural environmental conditions, and urban structural features. Terminals will evolve into intelligent devices capable of sensing the actions and states of people, objects, and other terminals. Integrated sensing will endow 6G networks with the ability to perceive the physical world in real time, enabling real-time processing and analysis of the perceived results with the combined support of network and computing power.

[0102] 3. AI Capabilities: AI capabilities in 6G networks refer to the provision of AI services to users and external parties, both for network operation and maintenance and through the inherent construction of AI elements (computing power, algorithms, and data). Under the orchestration, management, and control of integrated AI and connectivity elements, this enables on-demand customization of AI services and high QoS + rights protection. Native AI capabilities will be a core capability of 6G networks, specifically including training, inference, and model validation functions. The network side will provide lifecycle management functions for AI models and data, such as AI data (e.g., training data reporting, gradient reporting), AI models (e.g., model generation, model storage, model selection, model distribution, model updates, model replacement, model activation and deactivation, model performance monitoring), and AI computing power (e.g., allocation of computing resources for training execution and inference execution).

[0103] Furthermore, the inherent AI capabilities in 6G networks will enhance the intelligent experience of communication, transforming "symbol-level" communication services focused on bit-level information transmission into "meaning-oriented" communication services focused on high-level semantic delivery, thus breaking through the traditional "Shannon limit." By combining AI task orchestration and distributed computing power scheduling across the edge, cloud, and device layers, multimodal and barrier-free communication among natural persons, digital persons, and intelligent and non-intelligent devices will ultimately be achieved.

[0104] 4. Computing Power Capabilities: 6G computing capabilities will include computing awareness, computing control, and computing execution. The computing awareness function is responsible for collecting information on computing nodes within the network management domain; the computing control function will provide ubiquitous computing power control and scheduling strategies based on computing service needs; and the computing execution function will provide services such as session management, traffic control, policy execution, and QoS control based on the scheduling strategies. It is worth noting that computing needs to coordinate with connectivity functions to optimize the efficiency and overall energy consumption of new services such as AI. For example, for AI computing offloading services, the control plane, in coordination with computing awareness and computing control functions, can flexibly select appropriate network paths for computing offloading services, establish a channel for communication and computing convergence, and forward service traffic to the correct computing nodes, providing QoS guarantees for service consistency across computing. Through enhancements to the mobile network in computing power scheduling mechanisms and protocol systems, rapid, flexible, and on-demand service request scheduling, as well as joint and collaborative orchestration scheduling of computing and network resources, will be achieved, realizing deep integration of multi-dimensional perception, collaborative communication, and intelligent computing capabilities.

[0105] The introduction of computing capabilities into 6G networks involves not only changes in network architecture but also the formation of a unified environment for continuous computing services across the edge network and cloud, enabling computing tasks to select the optimal computing node based on latency, bandwidth, computing power, and energy efficiency requirements among terminals, networks, edge nodes, and the cloud.

[0106] 5. Data Capabilities: 5G-based communication networks serve as "pipelines" for communication session data transmission, facilitating information exchange between terminals and the network. 6G will continue to provide point-to-point transmission of communication session data. Simultaneously, data generated and consumed by intelligence, sensing, and network operations within 6G networks requires distributed data collection, preprocessing, storage, and analysis. Therefore, 6G networks need a data service function distinct from traditional user plane technologies to systematically address the challenges of managing and monetizing non-traditional user plane data in 6G mobile information service networks.

[0107] 6G data functionality comprises data orchestration and control, data processing and forwarding, and data storage. Based on the capability matrix reported by the data processing and forwarding nodes and specific data service requirements, the data orchestration and control nodes select data sources and processing and forwarding nodes, orchestrating them to form a data bearer to provide data services. This data bearer possesses the capability for on-the-fly processing and arbitrary topology. The data processing and forwarding nodes provide data services on demand, such as data acquisition, data preprocessing, data storage, data privacy protection and secure data analysis, data sharing, and data forwarding. While 5G networks have multiple data storage functions, such as UDR, UDSF, and ADRF, 6G networks will construct a unified data storage function, enabling rapid indexing and intelligent adaptation of distributed data, allowing for on-demand retrieval. Furthermore, standardization throughout the entire data lifecycle can improve data comparability and reusability, including processes such as data privacy and security, coordinated data generation and collection, data storage, data transmission, data processing, data services, data quality, and rights management.

[0108] In this embodiment of the disclosure, 6G is a centralized and distributed network, with a central network node managing multiple distributed network nodes. The functions of these distributed network nodes are different, meaning they can have different capabilities depending on the business requirements. For example, some network nodes have AI capabilities and computing power capabilities, while other network nodes have connectivity and sensing capabilities. Therefore, the capabilities of these network nodes are heterogeneous.

[0109] In the embodiments of this disclosure, the state of a certain capability of different network nodes may vary at different times or in different scenarios. For example, the AI ​​capability of network node 1 may be available to the outside world at time T1, but may not be available to the outside world at time T2. Therefore, changes in the terminal's CN NF and network nodes, as well as changes in the capability state of network nodes, will affect the continuity of terminal services. For example, please refer to Table 1 below, which shows examples of the capabilities and capability states of a 6G network provided in an embodiment of this disclosure.

[0110] Table 1

[0111] As shown in Table 1 above, the capability status of a 6G network varies depending on the time, location, and policy. Taking the capabilities of a 6G network, such as connectivity, sensing, AI, computing, and data, as an example, the table lists the capability status (service availability, service non-availability, etc.) at different times (T), locations (A), and policies (P). "Yes" indicates that service is available, and "No" indicates that service is not available. For example, the 6G network shown in Table 1 has connectivity, AI, and data capabilities at different times, but lacks sensing and computing capabilities; it has connectivity, sensing, and data capabilities at different locations, but lacks AI and computing capabilities; and it has connectivity, AI, and data capabilities under different policies, but lacks sensing and computing capabilities.

[0112] It should be noted that Table 1 above is only an example, and the scenarios are included but not limited to those listed. For example, 6G networks may have capabilities beyond those mentioned above, such as connectivity, sensing, AI, computing, and data, and their states may vary depending on the time, location, and policy.

The name of the terminal may differ in different systems; for example, in a 5G or 6G system, the terminal may be called User Equipment (UE). The wireless terminal can be a USB storage device, other personal computer memory devices, and a dongle. It can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminals. Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

Each node represents a core network that is customized on demand or has complete functionality. The centralized node possesses full functionality and business characteristics and can manage all distributed network nodes.

Since the methods and apparatus solve problems in similar principles, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0120] It should be noted that, in the embodiments of this disclosure, a node can refer to a basic functional unit in a network. It can be a hardware device, a software system, or a combination of both, used to perform specific network functions. In some embodiments, the name of "node" is not limited. For example, "node" can be used interchangeably with terms such as "network node," "network element," "network device," "network function," and "network element."

[0121] Figure 2a is an interactive schematic diagram of a business processing method provided in an embodiment of this disclosure. As shown in Figure 2a, the business processing method includes the following steps:

[0122] S211. When the first node determines that it cannot continue to process the terminal's first service, it sends a first instruction message to the terminal.

[0123] In some embodiments, the first node is the node currently providing services to the terminal and meeting the terminal's service needs. The terminal's services include a first service.

[0124] In some embodiments, the first node is the localized services provided by the PLMN.

[0125] In some embodiments, the first node is localized services.

[0126] In some embodiments, the first node can be replaced with localized services provided by PLMN.

[0127] In some embodiments, the first node can be replaced with localized services.

[0128] In some embodiments, when the localized services provided by the PLMN determine that the terminal's first service cannot be processed, they send a first indication message to the terminal.

[0129] In some embodiments, the first service may be one service; or, the first service may be multiple services (i.e., multiple services processed by the first node for the terminal cannot be processed further).

[0130] In some embodiments, the first indication information is used to indicate that the first node cannot continue to process the first service of the terminal.

[0131] In this embodiment of the disclosure, when a first node cannot provide a certain service to a terminal at a certain time, in a certain region, or under a certain policy, that is, when the first node determines that it cannot process the corresponding service of the terminal. For example, taking AI service as an example, if the first node does not have AI capabilities at time T1, then the first node cannot continue processing the AI ​​service at time T1. At this time, the first node will indicate to the terminal that it cannot continue processing the terminal's AI service. Specifically, the first node can send a first indication message to the terminal to indicate that the first node cannot continue processing the terminal's first service.

[0132] In some embodiments, the first node can send the first instruction information to the terminal by triggering a service modification request.

[0133] In some embodiments, the second node and the first node can synchronize terminal service information. This service information includes, but is not limited to, at least one of the following:

[0134] Terminal registration information;

[0135] Terminal session information;

[0136] The context of the terminal's business;

[0137] The terminal's contract data.

[0138] S212. The terminal migrates its services to the second node according to the first instruction information.

[0139] In some embodiments, the service in step S212 above is the service to be migrated from the terminal.

[0140] In some embodiments, the service includes a first service. That is, when a portion of the service established by the terminal at the first node (e.g., the first service) can no longer be processed, the terminal can migrate only that portion of the service. Other services that can continue to be processed at the first node, excluding the first service, will still be processed by the first node. For example, if the services processed by the terminal at the first node include service 1, service 2, and service 3, when the first node can no longer process service 1 (service 1 being the first service), the terminal can migrate service 1 to the second node, where the first node will continue processing services 2 and 3, and the second node will process service 1.

[0141] In some embodiments, the service further includes a second service. The second service is any service established by the terminal at the first node other than the first service. That is, when some services established by the terminal at the first node (e.g., the first service) can no longer be processed, the terminal can migrate all services established at the first node. For example, if the services processed by the terminal at the first node include service 1, service 2, and service 3, when the first node can no longer process service 1 (service 1 being the first service), the terminal can migrate services 1, 2, and 3 to the second node, where the second node will process services 1, 2, and 3.

[0142] In some embodiments, the first node can act as a relay between the second node and the terminal, sending service-related information of the services migrated to the second node to the second node.

[0143] In some embodiments, the second node may be indicated to the terminal by the first node. For example, when the first node determines that it cannot continue processing the terminal's first service, it may determine a second node that can process the first service and indicate the second node to the terminal; accordingly, the terminal may migrate its service to the second node indicated by the first node.

[0144] In some embodiments, the second node may be pre-configured or pre-defined. For example, at least one node capable of handling terminal services may be pre-configured for the terminal. When the first node can no longer handle the terminal's services, the terminal determines a second node from the at least one node to handle the terminal's services and migrates the services to that second node.

[0145] In some embodiments, the second node may be determined by the terminal itself. Specifically, the second node may be determined by the terminal based on one or more other nodes indicated by the first node, as well as the capabilities and / or status of those other nodes. For example, the first node may send the capabilities and capability status information of other nodes to the terminal, and the terminal may determine, based on the capabilities and capability status information of the other nodes, a second node whose capabilities and capability status information meet the business requirements.

[0146] Among them, capability information is used to indicate the types of services that a node can provide, and capability status information is used to indicate whether a node is currently able to provide the services corresponding to the types of services.

[0147] For example, if the first service is an AI service, the terminal can migrate the first service to a second node that can meet the needs of the AI ​​service. The second node will then provide services for the terminal's first service, ensuring its normal operation. In some embodiments, when the terminal has multiple services of different types, different types of services can be migrated to different second nodes. For example, if service 1 is an AI service and service 2 is a sensing service, service 1 can be migrated to second node 1 (e.g., distributed node 2), and service 2 can be migrated to second node 2 (e.g., distributed node 3).

[0148] In some embodiments, the second node is localized services provided by the PLMN.

[0149] In some embodiments, the second node is localized services.

[0150] In some embodiments, the second node can be replaced with localized services provided by the PLMN.

[0151] In some embodiments, the second node can be replaced with localized services.

[0152] In some embodiments, the terminal migrates its services to the localized services provided by the PLMN according to the first instruction information.

[0153] In some embodiments, when the localized services provided by the PLMN determine that they can no longer process the terminal's first service, they send a first instruction message to the terminal, and the terminal migrates its service to another localized service provided by the PLMN according to the first instruction message.

[0154] It is understandable that when both the first node and the second node are localized services provided by PLMN, the localized services provided by PLMN for the first node are different from those for the second node.

[0155] The solution provided in this embodiment allows the first service to be promptly migrated to other nodes when the first node is unable to process the first service for the terminal. This avoids the impact of changes in the capability status of each node on the continuity of the terminal's services, thereby ensuring the continuity of the terminal's services and improving the user experience.

[0156] Figure 2b is a second interactive schematic diagram of a business processing method provided in an embodiment of this disclosure. As shown in Figure 2b, the business processing method includes the following steps:

[0157] S221, The first node sends the second instruction information to the terminal.

[0158] In some embodiments, the second indication information is used to indicate the capability information and / or capability status information of at least one node. The capability information is used to indicate the service types that the node can provide, and the capability status information is used to indicate whether the node is currently able to provide the service corresponding to the service type.

[0159] In some embodiments, the second indication information may be sent to the terminal during the establishment of a service session between the terminal and the first node. For example, the second indication information may be carried in a service establishment response message sent by the first node to the terminal.

[0160] S222. When the first node determines that it cannot continue to process the terminal's first service, it sends a first instruction message to the terminal.

[0161] In some embodiments, the first indication information is used to indicate that the first node cannot continue to process the first service of the terminal.

[0162] In some embodiments, step S221 is optional. For example, the content of the second indication information can be carried in the first indication information and sent synchronously to the terminal. That is, the first indication information is used to indicate that the first node cannot continue to process the terminal's first service, and at the same time, it is also used to indicate the capability information and / or capability status information of at least one node.

[0163] In some embodiments, the first node can send the first instruction information to the terminal by triggering a service modification request.

[0164] S223. The terminal determines the second node based on the second instruction information.

[0165] In some embodiments, the second node is a node among at least one node indicated in the second indication information.

[0166] Specifically, the second node can be determined by the terminal based on the capabilities and / or status of at least one node indicated by the first node. For example, the terminal can determine a second node whose capabilities and capability status information meet the business requirements from at least one node, based on the capabilities and capability status information of at least one node.

[0167] For example, if the first service is an AI service, the terminal can migrate the first service to a second node whose capabilities and capability status information can meet the needs of the AI ​​service. The second node will then provide services for the terminal's first service, ensuring its normal operation.

[0168] In some embodiments, the number of second nodes determined by the terminal can be one or more. For example, when the terminal has multiple services to migrate and these services are of different types, the terminal can determine one or more second nodes from at least one node that can handle the multiple services of the terminal, based on the capability and / or capability status information of at least one node.

[0169] S224. The terminal migrates its services to the second node according to the first instruction information.

[0170] In some embodiments, the service in step S224 above is the service to be migrated from the terminal.

[0171] In some embodiments, the service includes a first service.

[0172] In some embodiments, the service further includes a second service. The second service is a service established by the terminal at the first node, other than the first service.

[0173] It should be noted that the implementation of step S224 is described in step S212 of the embodiment shown in Figure 2a, and will not be repeated here.

[0174] S225, The terminal sends a first request message to the first node.

[0175] In some embodiments, the first request message is used to request the release of resources corresponding to the service.

[0176] S226. The first node releases the resources corresponding to the service based on the first request message.

[0177] S227, the terminal and the second node transmit service data.

[0178] In some embodiments, a terminal can send service data of a service to a second node through a first node.

[0179] Specifically, the first node can receive service data sent by the terminal and forward the service data to the second node; and / or, the first node can also receive service data sent by the second node and forward the service data to the terminal; wherein, the second node is the node for the terminal to migrate services.

[0180] In some embodiments, the terminal can also directly send service data to the second node.

[0181] The solution provided in this embodiment allows the first service to be promptly migrated to other nodes when the first node is unable to process the first service for the terminal. This avoids the impact of changes in the capability status of each node on the continuity of the terminal's services, thereby ensuring the continuity of the terminal's services and improving the user experience.

[0182] Furthermore, in this embodiment of the present disclosure, the terminal can accurately determine the second node based on the node's capability information and / or capability status information, thereby enabling the determined second node to handle the migrated services and ensuring service continuity.

[0183] Figure 2c is a schematic diagram of the interaction of a business processing method provided in an embodiment of this disclosure. As shown in Figure 2c, the business processing method includes the following steps:

[0184] S231. When the first node determines that it cannot continue to process the terminal's first service, it sends a first instruction message to the terminal.

[0185] In some embodiments, the first indication information is used to indicate that the first node cannot continue to process the first service of the terminal.

[0186] It should be noted that the implementation of step S231 can refer to step S211 in the embodiment shown in Figure 2a above, and will not be repeated here.

[0187] S232, The first node sends the third instruction information to the terminal.

[0188] In some embodiments, the third indication information is used to indicate a second node, which is a node capable of processing the terminal's services.

[0189] In some embodiments, step S232 is optional. For example, the content of the third indication information can be carried in the first indication information and sent synchronously to the terminal. That is, the first indication information is used to indicate that the first node cannot continue to process the terminal's first service, and at the same time, the first indication information is also used to indicate that the second node can process the service.

[0190] In some embodiments, the number of second nodes indicated by the first node can be one or more. For example, when the first node determines that it cannot continue to process the first service, it determines one or more second nodes from at least one node that can process the terminal's service based on the capability and / or capability status information of at least one node, and indicates the second nodes to the terminal through third indication information (or first indication information).

[0191] In some embodiments, the first node can send the first instruction information to the terminal by triggering a service modification request.

[0192] In some embodiments, the first node is determined from at least one node based on the capability and / or capability status information of at least one node.

[0193] S233. The terminal determines the second node based on the third instruction information.

[0194] S234. The terminal sends a first request message to the first node.

[0195] In some embodiments, the first request message is used to request the release of resources corresponding to the service.

[0196] S235. The first node releases the resources corresponding to the service based on the first request message.

[0197] S236. The terminal migrates its services to the second node according to the first instruction information.

[0198] In some embodiments, the service in step S236 above is the terminal's service to be migrated.

[0199] In some embodiments, the service includes a first service.

[0200] In some embodiments, the service further includes a second service. The second service is a service established by the terminal at the first node, other than the first service.

[0201] It should be noted that the implementation of step S236 is described in step S212 of the embodiment shown in Figure 2a, and will not be repeated here.

[0202] In some embodiments, when the number of second nodes indicated by the third indication information is one, the terminal can migrate its services to the second node indicated by the third indication information.

[0203] In some embodiments, when there are multiple second nodes indicated by the third indication information, the terminal can perform service migration in, but is not limited to, the following ways:

[0204] Method 1: When the number of second nodes indicated by the third instruction information is multiple and the service to be migrated is one, the terminal can randomly select a node from the multiple second nodes and migrate the service to be migrated to that node.

[0205] Method 2: When the number of second nodes indicated by the third instruction information is multiple and the number of services to be migrated is multiple but of the same type, a node can be randomly selected to handle all services; or multiple nodes can be selected to handle different services respectively.

[0206] Method 3: When the third instruction information indicates multiple second nodes and multiple services of different types to be migrated, the node to process each service can be determined based on the type of each service to be migrated and the capabilities and / or capability status information of the multiple second nodes. For example, if the services to be migrated are Service 1 (AI service), Service 2 (perception service), and Service 3 (computing service); and the third instruction information indicates Node 1 (currently capable of processing AI and computing services) and Node 2 (currently capable of processing perception services), then Service 1 and Service 3 can be migrated to Node 1, and Service 2 can be migrated to Node 2.

[0207] S237, the terminal and the second node transmit service data.

[0208] In some embodiments, a terminal can send service data of a service to a second node through a first node.

[0209] Specifically, the first node can receive service data sent by the terminal and forward the service data to the second node; and / or, the first node can also receive service data sent by the second node and forward the service data to the terminal; wherein, the second node is the node for the terminal to migrate services.

[0210] In some embodiments, the terminal can also directly send service data to the second node.

[0211] The solution provided in this embodiment allows the first service to be promptly migrated to other nodes when the first node is unable to process the first service for the terminal. This avoids the impact of changes in the capability status of each node on the continuity of the terminal's services, thereby ensuring the continuity of the terminal's services and improving the user experience.

[0212] Furthermore, in this embodiment, the first node instructs the terminal to identify the second node for migrated services, ensuring the accuracy of the second node and its ability to process the migrated services, thus guaranteeing service continuity. Additionally, by having the first node indicate the second node for migrated services to the terminal, the terminal does not need to determine the second node, reducing its data processing load, increasing service migration speed, and ensuring service continuity.

[0213] Figure 2d is an interactive schematic diagram of a business processing method provided in an embodiment of this disclosure. As shown in Figure 2d, the business processing method includes the following steps:

[0214] S241. When the first node determines that it cannot continue to process the terminal's first service, it sends a first instruction message to the terminal.

[0215] In some embodiments, the first indication information is used to indicate that the first node cannot continue to process the first service of the terminal.

[0216] In some embodiments, step S241 is optional. For example, when the first node determines that it cannot continue to process the first service of the terminal, it can directly execute step S242 to migrate the terminal's service to the second node.

[0217] In some embodiments, the implementation of step S241 can refer to step S211 in the embodiment shown in FIG2a above, and will not be repeated here.

[0218] S242, The first node migrates the terminal's services to the second node.

[0219] In some embodiments, the service in step S242 above is the terminal's service to be migrated.

[0220] In some embodiments, the service includes a first service. That is, when one of the services (e.g., the first service) established by the terminal at the first node can no longer be processed, the first node can migrate only that service. Other services that can continue to be processed at the first node, excluding the first service, will still be processed by the first node. For example, if the services processed by the terminal at the first node include service 1, service 2, and service 3, when the first node can no longer process service 1 (service 1 being the first service), the first node can migrate service 1 to the second node, whereby the first node continues to process services 2 and 3, and the second node processes service 1.

[0221] In some embodiments, the service further includes a second service. The second service is any service established by the terminal at the first node other than the first service. That is, when one of the services established by the terminal at the first node (e.g., the first service) can no longer be processed, the first node can migrate all services established at the first node. For example, if the services processed by the terminal at the first node include service 1, service 2, and service 3, when the first node can no longer process service 1 (service 1 being the first service), the first node can migrate services 1, 2, and 3 to the second node, where the second node will process services 1, 2, and 3.

[0222] In some embodiments, when a terminal has multiple services to be migrated and the service types are different, the first node can migrate different types of services to different second nodes. For example, service 1 is an AI service and service 2 is a perception service; service 1 can be migrated to second node 1 (e.g., distributed node 2), and service 2 can be migrated to second node 2 (e.g., distributed node 3).

[0223] In some embodiments, the first node is determined from at least one node based on the capability and / or capability status information of at least one node.

[0224] S243, The first node releases the resources corresponding to the service.

[0225] S244, The first node transmits service data.

[0226] In some embodiments, the first node can transmit service data via transparent transmission. That is, the second node handles the services migrated from the terminal, the first node obtains the service data processed by the second node, and sends the service data to the terminal. Correspondingly, the first node can also obtain service data sent by the terminal and send the service data to the second node.

[0227] In some embodiments, the second node is localized services provided by the PLMN.

[0228] In some embodiments, the first node can be replaced with localized services.

[0229] In some embodiments, the second node is localized services provided by the PLMN.

[0230] In some embodiments, the second node can be replaced with localized services.

[0231] With the solution of this embodiment, when the first node is unable to process the first service for the terminal, the first node can promptly migrate the first service to other nodes, avoiding the impact of changes in the capability status of each node on the continuity of the terminal's services, thereby ensuring the continuity of the terminal's services and improving the user experience.

[0232] Furthermore, this process does not require terminal involvement, which can reduce signaling interaction, lower terminal processing pressure, improve service migration efficiency, ensure service continuity, and enhance user experience.
