Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a network node adaptation method, apparatus, and storage medium. Background Art

[0002] The current native design of 5G mobile communication network systems is centralized control. With the emergence of emerging services and scenarios and the development of the network, the trend of 6G networks is a combined centralized and distributed network architecture. 6G will build distributed network nodes with different functions, and different network nodes will have different capabilities, permissions, and service scopes. At the same time, new service scenarios represented by immersive XR, holographic communication, etc. have put forward higher requirements for the network, including not only the enhancement of traditional connection services, but also the expansion of new capabilities or new services such as computing power services, AI services, and data services.

[0003] In traditional technologies, a distributed network can select or generate a network node that meets the user's initial requirements according to the user's needs. For example, if a user requests a connection service, the network can select a network node that can provide the connection service; if a user requests a computing power service, the network can select a network node that can provide a data service; if a user requests a connection service and a computing power service, the network can select or generate a network node that can provide both the connection service and the computing power service. However, at different times, the user's service state will change dynamically, and the functions and / or performance of the network nodes required for different services will also be different. For example, at different times, large-bandwidth services, computing power services, intelligent services, etc. will be initiated, resulting in the original network nodes no longer being applicable. Therefore, there is an urgent need for a network node adaptation method that can quickly adapt to changes in the UE state to dynamically meet the needs of the UE. Summary of the Invention

[0100] The network node adaptation method provided by the embodiments of this application can be applied to Figure 2 the application scenario shown in Figure 2 . As

[0101] The technical solutions provided by the embodiments of the present application can be applicable to a variety of systems. For example, the applicable systems can be Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, etc. These various systems can include terminal devices and network devices. The system can also include a core network part, such as an Evolved Packet System (EPS), a 5G system (5GS), etc.

[0102] The terminal device involved in the embodiments of the present application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be referred to as a User Equipment (UE). The wireless terminal device can be a USB storage device, other personal computer memory devices, and dongles. It can also communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, Machine-type Communication (MTC) terminal devices, etc. The wireless terminal device can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, and wireless access points and routers / modems that meet the limitations of this definition. The embodiments of the present application do not limit this.

[0103] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells that provide services to terminals. Depending on specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or other names. The network device can be used to mutually replace the received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the attributes of the air interface. For example, the network device involved in the embodiments of the present application may be an evolved network device (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), etc., or may also be a Home evolved Node B (HeNB), a relay node, a femto, a pico, a network test device, etc. The embodiments of the present application do not limit this. In some network architectures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged separately geographically.

[0104] In the embodiments of the present application, the terminal device sends relevant information or similar descriptions to the network-side device, which only indicates that the relevant information is sent in the form of a wireless signal, and the intended recipient is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0105] In an exemplary embodiment, as Figure 3 shown, a network node adaptation method is provided. Taking the distributed network shown in Figure 2 as an example for illustration. As Figure 3 shown, the method may include:

[0106] Step S301, the terminal device sends a service request to the RAN.

[0107] Among them, the service request includes the service type, and the service request can be used to request the establishment of a service of this service type for the terminal device.

[0108] Step S302, the RAN receives the service request sent by the terminal.

[0109] Step S303: In response to the service request, the RAN sends a service establishment request to the target network node.

[0110] Among them, the target network node can represent the network node among the multiple network nodes connected to the RAN that can meet the service requirements of the terminal device. The target node can be determined based on the service type of the terminal device and the information attributes of each network node connected to the RAN. The information attributes can be used to indicate the capabilities of the network node.

[0111] Step S304: In response to the service establishment request, the target network node establishes a service.

[0112] Step S305: The target network node sends a service request response to the terminal device.

[0113] Among them, the service request response can be used to indicate that the service establishment is completed.

[0114] In the above network node adaptation method, when a RAN is connected to multiple network nodes, the target network node can be determined based on the service type of the terminal device and the information attributes of each network node connected to the RAN, so that for the requests initiated by the terminal device at any time, a suitable target network node can be quickly adapted to establish a service, realizing the dynamic adaptation of network nodes in a distributed network and better meeting the service requirements of the terminal device.

[0115] In step S301, the service request includes the service type, and the service request can be used to request to establish a service of this service type for the terminal device. When the terminal device initiates a service, it can send a service request carrying the service type of this service to the RAN. After receiving the service request, the RAN can establish a service of this service type for the terminal device through the network node.

[0116] In a possible implementation, the terminal device can send a service request to the RAN when initiating a service for the first time; the terminal can also send a service request to the RAN after the service changes. For example, at the first moment, the terminal device needs to initiate Service 1 and sends a service request for Service 1 to the RAN. At the second moment, the service of the terminal device changes from Service 1 to Service 2 and it needs to initiate Service 2, so it can send a service request for Service 2 to the RAN at the second moment.

[0117] Among them, the service type can be divided as needed. In one example, the service type can include large broadband services, intelligent services, data processing services, etc. In another example, the service type can include instant messaging services, video services, voice services, etc.

[0118] In response to a service request, the RAN may send a service establishment request to a target network node, so that the target network node establishes a service for the terminal device according to the corresponding service type.

[0119] Among them, the target network node may represent a network node among multiple network nodes connected to the RAN that can meet the service requirements of the terminal device. The target node may be determined based on the service type and the information attributes of each network node connected to the RAN of the terminal device.

[0120] Among them, the information attribute may be used to indicate the capabilities of the network node. In one example, the information attributes of the network node may include the network node identifier, the list of the capability types of the network node, the service range of the network node, the resource situation of the network node, and the location information of the network node, etc. Among them, the network node identifier may be used to identify a unique network node, and the network node identifier may be the number or IP address of the network node, etc. The list of the capability types of the network node may be used to indicate the capability types possessed by the network node. In one example, the network node may include the capability of processing large bandwidth services, the capability of intelligent services, and the capability of data processing services, etc. In a possible implementation manner, when the network node has multiple types of capabilities, one type of capability may be set as the main capability, and the remaining types of capabilities may be set as the auxiliary capabilities. The network node may preferentially provide the main capability externally.

[0121] In the embodiments of the present application, the target information attribute may be determined by the terminal device based on the service type of the terminal device and the information attributes of each network node connected to the RAN, or the target information attribute may be determined by the RAN based on the service type of the terminal device and the information attributes of each network node connected to the RAN, and then the target network node is determined. The following describes these two methods separately.

[0122] In a possible implementation manner, the service request may include the service type and the target information attribute. The target information attribute may be used to represent the information attribute of the target network node. At this time, the terminal device determines the target information attribute based on the service type of the terminal device and the information attributes of each network node connected to the RAN. Then, the RAN determines the target network node according to the target information attribute.

[0123] In one example, the RAN stores the information attributes of each network node it is connected to. The terminal device can obtain the information attributes of each network node connected to the RAN from the RAN. For example, the terminal device can send a Radio Resource Control (RRC) connection establishment request to the RAN. The RAN can carry the information attributes of each network node connected to the RAN in the RRC connection establishment request response sent back to the terminal device. After receiving the RRC connection establishment request response sent by the RAN, the terminal device can obtain the information attributes of each network node connected to the RAN from the RRC connection establishment request response. Of course, the terminal device can also obtain the information attributes of each network node connected to the RAN from the RAN during the interaction process after establishing an RRC connection with the RAN. In the embodiments of this application, there are no restrictions on the method and timing for the terminal device to obtain information attributes from the RAN.

[0124] In another example, the terminal device can obtain the information attributes of each network node connected to the RAN from a third party. Among them, the third party can be a management platform, an orchestration manager, or a central node, etc. The management platform can be used to manage network nodes, so the information attributes of each network node can be obtained from the management platform. The orchestration management platform can be used to orchestrate and manage network nodes, so the information attributes of each network node can be obtained from the orchestration management platform. The central node can be used to manage each network element in the network, so the information attributes of each network node can be obtained from the central node.

[0125] After the terminal device obtains the information attributes of each network node connected to the RAN, it can determine the target information attributes, that is, the information attributes of the target network node, according to the service type of the terminal device and these obtained information attributes.

[0126] In one possible implementation, the terminal device can determine the target network node according to the information attributes whose capabilities match the service type among the information attributes of each network node connected to the RAN.

[0127] In one example, if there is an attribute information among the information attributes of each network node connected to the RAN whose capability matches the service type of the terminal device, then the network node corresponding to the attribute information that matches the service type of the terminal device is determined as the target network node. That is to say, the attribute information that matches the service type of the terminal device can be first determined as the target information attribute, and then the network node corresponding to the target information attribute is determined as the target network node. For example, the information attributes of each network node connected to the RAN are information attribute 1, information attribute 2, and information attribute 3. Among them, the capabilities indicated by information attribute 1 are the capabilities of processing large bandwidth services and intelligent services, the capability indicated by information attribute 2 is the capability of intelligent services, and the capabilities indicated by information attribute 3 are the capabilities of intelligent services and data processing services. If the service type of the terminal device is a data processing service, the capability of information attribute 3 matches the service type of the terminal device, information attribute 3 is the target information attribute, and the network node corresponding to information attribute 3 is the target network node.

[0128] In one example, if there are multiple information attributes among the information attributes of each network node connected to the RAN whose capabilities match the service type of the terminal device, then the information attribute with the smallest corresponding capability among these information attributes is determined as the target information attribute. Referring to the above example, if the service type of the terminal device is an intelligent service, the capabilities of information attribute 1, information attribute 2, and information attribute 3 all match the service type of the terminal device. The information attribute with the smallest intelligent service capability among information attribute 1, information attribute 2, and information attribute 3 can be determined as the target information attribute, and the network node corresponding to this target information attribute is the target network node.

[0129] In the embodiments of the present application, when selecting the target information attribute or the target network node, the principle of the minimum capability set that conforms to the service of the terminal device is adopted, which can provide guarantee for the services of other terminal devices. For example, assume that the bandwidths of network node 1 and network node 2 are 100M and 30M respectively. If the service of terminal device 1 requires 20M bandwidth, at this time both network node 1 and network node 2 can serve it. However, if network node 1 is selected to serve it, when a certain service of terminal device 2 also requires 100M bandwidth, since network node 1 has been allocated to serve terminal device 1, there is no sufficient bandwidth to meet the network node requirements of the service of terminal device 2 at this time. Therefore, the network node with the appropriate minimum set of capabilities is selected according to the service of the terminal device, so as to ensure that other network nodes can serve the services of other terminal devices, and avoid the situation where the services of the terminal device cannot be satisfied due to improper selection or update.

[0130] When the service request includes the service type and the target information attribute, after receiving the service request, the RAN can obtain the target information attribute from the service request, and then determine the network node corresponding to the target information attribute as the target network node. In one example, the RAN can determine the network node with the same information attribute as the information attribute information as the target network node. In another example, the RAN can determine the network node corresponding to the network node identifier in the target information attribute as the target network node.

[0131] In a possible implementation, the service request may include the service type. At this time, the RAN determines the target information attribute based on the service type of the terminal device and the information attributes of each network node connected to the RAN, and then determines the target network node.

[0132] The information attributes of each network node connected to the RAN are stored in the RAN. In one example, the information attributes stored in the RAN can be pre-configured. In another example, the RAN can obtain the information attributes of each network node connected to it through a third party. Among them, the third party can be a management platform, an orchestration manager, a central node, etc.

[0133] In response to the service request, the RAN can determine the target information attribute according to the information attribute whose capability matches the service type among the information attributes of each network node connected, and determine the network node corresponding to the target attribute information as the target network node. Among them, the process of the RAN determining the target information attribute can refer to the process of the terminal device determining the target information, which will not be elaborated here.

[0134] After that, in response to the service request, the RAN can send a service establishment request to the target network node. The service establishment request can be used to request the target network node to establish a service of the service type required by the terminal device.

[0135] In response to the service establishment request, the target network node can establish a service to meet the service requirements of the terminal device. Among them, in a distributed network, the target network node can include at least one AMF, at least one SMF, and at least one UPF.

[0136] In a possible implementation, in response to a service request, the RAN may determine a target AMF from at least one AMF of the target network node, and then send a service establishment request to the target AMF. The target AMF may determine a target SMF from at least one SMF of the target network node, and then send a service establishment request to the target SMF. After receiving the service establishment request, the target SMF determines a target UPF from at least one UPF of the target network node, and then the target UPF starts to process the service of the terminal device to establish a service for the terminal device. After the service is successfully established, the target SMF returns a service establishment request response to the target AMF. After receiving this response, the target AMF returns a service request response to the terminal device.

[0137] Among them, the process of determining the target AMF, target SMF, and target UPF may refer to related technologies. The interaction process between the target AMF and the target SMF, the interaction process between the target SMF and the target UPF, and the process of the target UPF establishing a service may refer to related technologies, which will not be elaborated here.

[0138] In the above network node adaptation method, when a RAN is connected to multiple network nodes, the target network node can be determined based on the service type of the terminal device and the information attributes of each network node connected by the RAN. Therefore, for a request initiated by the terminal device at any time, the appropriate target network node can be quickly adapted to establish a service, realizing the dynamic adaptation of network nodes in a distributed network and better meeting the service requirements of the terminal device.

[0139] The above considers selecting the target network node from multiple network nodes currently connected by the RAN. However, there may also be a situation where none of the multiple network nodes currently connected by the RAN can meet the service requirements of the terminal device. To meet the service requirements of the terminal device, in the embodiments of the present application, a new network node may be generated and the newly generated network node may be used as the target network node.

[0140] In a possible implementation, the network node adaptation method provided in the embodiments of the present application may further include: in the case that there is no target network node among the network nodes currently connected by the RAN, sending a node generation request to the manager; in the case of receiving a node generation request response sent by the manager, connecting to the new network node and determining the new network node as the target network node.

[0141] Among them, the management node may be a management and orchestration node (MANO) or a slice manager, etc. In the embodiments of the present application, there is no limitation on the management node, as long as it has the functions of network node generation and management.

[0142] The node generation request may include the service type of the terminal device. The node generation request can be used to request the generation of a new network node. It can be understood that the new network node can meet the service requirements of the terminal device. After the new network node is generated, the management node can send a node generation request response to the RAN, and the node generation request response is used to notify the RAN that the new network node has been generated and can be used. Therefore, after receiving the node generation request response, the RAN can connect to the new network node and determine the new network node as the target network node.

[0143] In one example, the RAN can directly determine the new network node as the target network node. In another example, after connecting to the new network node, the RAN can store the information attributes of the new network node, and then determine the target information attributes based on the service type of the terminal device and the information attributes of each connected network node (including the attribute information of the previously connected network node and the attribute information of the new network node), and then determine the target network node. Since the previous network nodes cannot meet the service requirements of the terminal device, but the new network node can meet the service requirements of the terminal device, the new network node is finally determined as the target network node.

[0144] In the above process, the method for the management node to generate a new network node and the method for the RAN to connect to the new network node can refer to the related technologies and will not be elaborated here.

[0145] In one example, at the first moment, after receiving the service request sent by the terminal device, the RAN finds that each currently connected network node cannot meet the service request of the terminal device. At this time, the RAN can send a node generation request to the manager; in the case of receiving the node generation request response sent by the manager, connect to the new network node and determine the new network node as the target network node.

[0146] In another example, at the first moment, after receiving the service request sent by the terminal device, the RAN determines the target network node, and the target network node provides service for the terminal device. At the second moment, the RAN finds that due to the change of the terminal device service or the previous target network node being interfered, each currently connected network node of the RAN cannot meet the service request of the terminal device. At this time, the RAN can send a node generation request to the manager; in the case of receiving the node generation request response sent by the manager, connect to the new network node and determine the new network node as the target network node.

[0147] The above network node adaptation method can urgently generate a new network node for the terminal device, realizes the dynamic adaptation of network nodes in a distributed network, and better meets the service requirements of the terminal device.

[0148] In an exemplary embodiment, as Figure 4 shown, a network node adaptation method is provided, and this method is described by taking the distributed network shown in Figure 2 as an example. In this embodiment, when a terminal device sends a service request, which carries both a service type and a target information attribute, after the RAN receives this service request, it can determine that the target network node provides service for the terminal device according to the target information attribute carried in the service request. As Figure 4 shown, this method may include:

[0149] Step S400: The terminal device obtains the information attributes of each network node connected to the RAN.

[0150] The terminal device can obtain the information attributes of each network node connected to the RAN from the RAN or a third party.

[0151] Step S401: At a first moment, the terminal device sends a service request to the RAN, and the service request carries a service type 1 and a network node information attribute 1.

[0152] Among them, the first moment can represent any moment. The service type 1 can represent the service type of the terminal device, and the service type 1 can be any service type. The network node information attribute 1 can represent the target node information attribute. When the target network node is network node 1, the network node information attribute 1 is the information attribute of network node 1.

[0153] Of course, the service request can also carry the information required when establishing a service, which can refer to the related technology and will not be elaborated here.

[0154] Step S402: The RAN selects the AMF of network node 1 according to the network node information attribute 1 carried in the service request.

[0155] Each network node may include at least one AMF, at least one SMF, and at least one UPF. When network node 1 includes one AMF, the RAN can send a service establishment request to this AMF. When network node 1 includes multiple AMFs, the RAN can first select one AMF from them, and then send a service establishment request to the selected AMF. The process of selecting the AMF can refer to the related technology and will not be elaborated here. The processing processes of the SMF and UPF can refer to the processing process of the AMF and will not be elaborated here.

[0156] Step S403: The RAN initiates a service establishment request to the AMF of network node 1.

[0157] The service establishment request can refer to the related technology and will not be elaborated here.

[0158] Step S404: The AMF of network node 1 selects the SMF of network node 1.

[0159] Step S405: The AMF of network node 1 sends a service 1 establishment request to the SMF of network node 1.

[0160] Service 1 represents the service of service type 1. This service 1 establishment request is used to request the SMF to establish user plane related resources for the terminal device.

[0161] Step S406: The service 1 establishment process is completed, and the UPF of network node 1 starts to process the service 1 of the terminal device.

[0162] Step S407: The SMF of network node 1 sends a service 1 establishment response to the AMF of network node 1.

[0163] Step S408: The AMF of network node 1 sends a service 1 request response to the terminal device.

[0164] This service 1 request response is the service request response sent by the target network node to the terminal device, and is used to indicate that the service 1 establishment is completed.

[0165] In an exemplary embodiment, as Figure 5 shown, a network node adaptation method is provided. Taking the case where this method is applied to the Figure 2 distributed network shown as an example for illustration. In this embodiment, when the terminal device sends a service request and only carries the service type, when the RAN receives this service request, it can select the target network node for the terminal device according to the service type of the terminal device to provide service for it. As Figure 5 described, this method may include:

[0166] Step S500: The RAN obtains the information attributes of each network node it is connected to.

[0167] The information attributes of each network node can be pre-configured on the RAN, or the information attributes of each network node can be obtained from a third party.

[0168] Step S501: At a first moment, the terminal device sends a service request, and the service type 1 is carried in this service request.

[0169] Step S502: The RAN selects the AMF of network node 1 according to the service type 1 carried in the service request.

[0170] Here, network node 1 is the target network node.

[0171] Step S503: The RAN initiates a service establishment request to the AMF of network node 1.

[0172] Step S504: The AMF of network node 1 selects the SMF of network node 1.

[0173] Step S505: The AMF of network node 1 sends a service 1 establishment request to the SMF of network node 1.

[0174] Step S506: The service 1 establishment process is completed, and the UPF of network node 1 starts to process service 1 of the terminal device.

[0175] Step S507: The SMF of network node 1 replies to the AMF of network node 1 with a service 1 establishment response.

[0176] Step S508: The AMF of network node 1 sends a service 1 request response to the terminal device.

[0177] In an exemplary embodiment, Figure 6 As shown, a network node adaptation method is provided, which is applied to Figure 2 This embodiment is for the case where the service type of the terminal device changes and the service request carries both the service type and the target information attribute. When the RAN receives a new service request, it updates the target network node served by the terminal device according to the target information attribute carried in the new service request. Figure 6 As shown, the method may include:

[0178] Step S601: Execute steps S400 to S408.

[0179] Step S602: At the second moment, the service type of the terminal device changes, and a service request is sent to the RAN. The service request carries service type 2 and network node information attribute 2.

[0180] The second moment may represent any moment after the first moment. Service type 2 may represent the service type after the terminal device changes, and service type 2 may be any service type different from service type 1. Network node information attribute 2 may represent the target node information attribute. When the target network node is network node 2, network node information attribute 2 is the information attribute of network node 2.

[0181] The business request here represents a business update request.

[0182] Step S603: RAN selects the AMF of network node 2 according to the network node information attribute 2 carried in the service request.

[0183] Step S604: RAN initiates a service establishment request to the AMF of network node 2.

[0184] The service establishment request here represents a service update establishment request.

[0185] Step S605: The AMF of network node 2 selects the SMF of network node 2.

[0186] Step S606: The AMF of network node 2 sends a service 2 establishment request to the SMF of network node 2.

[0187] Service 2 represents a service of service type 2. This service 2 establishment request is used to request the SMF to establish user plane related resources for the terminal device.

[0188] Step S607: The service 2 update establishment process is completed, and the UPF of network node 2 starts to process service 2 of the terminal device.

[0189] Step S608: The SMF of network node 2 sends a service 2 establishment response to the AMF of network node 2.

[0190] Step S609: The AMF of network node 2 sends a request response for service 2 to the terminal device.

[0191] This service 2 request response is the service request response sent by the target network node to the terminal device, and is used to indicate that the establishment of service 2 is completed.

[0192] In an exemplary embodiment, as Figure 7 shown, a network node adaptation method is provided, and this method is illustrated by taking the distributed network shown as an example. This embodiment is for the case where the service type of the terminal device changes and the service request only carries the service type. When the RAN receives a new service request, it updates the target network node that provides services for the terminal device according to the service type carried in the new service request. As Figure 2 shown, this method may include: Figure 7 shown, this method may include:

[0193] Step S701: Execute steps S500 to S508.

[0194] Step S702: At the second moment, the service type of the terminal device changes, and a service request is sent to the RAN. The service type 2 is carried in this service request.

[0195] Step S703: The RAN selects the AMF of network node 2 according to the service type 2 carried in the service request.

[0196] Step S704: The RAN sends a service establishment request to the AMF of network node 2.

[0197] Step S705: The AMF of network node 2 selects the SMF of network node 2.

[0198] Step S706: The AMF of network node 2 sends a service 2 establishment request to the SMF of network node 2.

[0199] This service 2 establishment request is used to request the SMF to establish user plane related resources for the terminal device.

[0200] Step S707: The service 2 establishment process is completed, and the UPF of network node 2 starts to process service 2 of the terminal device.

[0201] Step S708: The SMF of network node 2 sends a service 2 establishment response to the AMF of network node 2.

[0202] Step S709: The AMF of network node 2 sends a request response for service 2 to the terminal device.

[0203] In an exemplary embodiment, as Figure 8 shown, a network node adaptation method is provided. Taking the method applied to the Figure 2 distributed network shown as an example for illustration. In this embodiment, for all network nodes connected to the RAN serving the terminal device that have suffered strong internal or external burst interference, resulting in a sharp deterioration of network node functions, resources, etc., and being unable to meet the service requirements for the terminal device, a network node that can meet the service requirements can be urgently generated for the terminal device. As Figure 8 shown, the method may include:

[0204] Step S801: Execute step S400 to step S408 or execute step S500 to step S508.

[0205] Step S802: At the second moment, when the target network node suffers external interference and / or the service of the terminal device changes, and the RAN finds that the network node it is connected to can no longer serve the terminal device, the RAN sends a node generation request to the manager.

[0206] The node generation request includes the service type of the terminal device. Of course, the node generation request may also include other information for generating network nodes, which is not limited in this embodiment of the present application.

[0207] Among them, the manager can be a MANO or a slice manager, and its main function is to instantiate the network, that is, by inputting certain parameters, a network node that meets these parameters can be generated.

[0208] Step S803: After receiving the node generation request, the manager generates a new network node that can serve the terminal device according to the carried service type, and sends the information attributes of the new network node to the RAN.

[0209] Step S804: The RAN selects the AMF of network node 2 according to the information attributes of the new network node returned by the manager.

[0210] Here, network node 2 represents the new network node generated by the manager.

[0211] Step S805: The RAN initiates a service 3 establishment request to the AMF of network node 2.

[0212] Service 3 can be the same as service 1 or different from service 1.

[0213] Step S806: The AMF of network node 2 selects the SMF of network node 2.

[0214] Step S807: The AMF of network node 2 sends a service 3 establishment request to the SMF of network node 2.

[0215] This service establishment request is used to request the SMF to establish user plane related resources for the terminal device.

[0216] Step S808: The service 3 establishment process is completed, and the UPF of network node 2 starts to process service 3 of the terminal device.

[0217] Step S809: The SMF of network node 2 sends a service 3 establishment response to the AMF of network node 2.

[0218] Step S810: The AMF of network node 2 sends a request response of service 3 to the terminal device.

[0219] In an exemplary embodiment, as Figure 9 shown, a network node adaptation method is provided. Taking the method applied to Figure 2 the distributed network shown as an example for illustration. In this embodiment, when all network nodes connected to the RAN serving the terminal device cannot meet the service requirements of the terminal device, that is, cannot serve the changed service of the terminal device, a network node that can meet the service requirements can be urgently generated for the terminal device. As Figure 9 shown, the method may include:

[0220] Step S901: Execute step S400 to step S408 or execute step S500 to step S508.

[0221] Step S902: At the second moment, the service of the terminal device changes, and a service request is sent to the RAN. The service type 2 is carried in the request.

[0222] Step S903: The RAN discovers that the network nodes it is connected to can no longer serve the new service of the terminal device, then the RAN sends a node generation request to the manager.

[0223] Among them, the new business is the business corresponding to business type 2.

[0224] Step S904: After receiving the node generation request, the manager generates a new network node that can serve the terminal device according to the carried service type, and sends information attributes of the new network node to the RAN.

[0225] Step S905: RAN selects the AMF of network node 2 according to the information attributes of the new network node returned by the manager.

[0226] Step S906: RAN initiates a service 2 establishment request to the AMF of network node 2.

[0227] Step S907: The AMF of network node 2 selects the SMF of network node 2.

[0228] Step S908: The AMF of network node 2 sends a service 2 establishment request to the SMF of network node 2.

[0229] Step S909: The service 2 establishment process is completed, and the UPF of network node 2 starts to process service 2 of the terminal device.

[0230] Step S910: The SMF of network node 2 replies to the AMF of network node 2 with a service 2 establishment response.

[0231] Step S911: The AMF of network node 2 sends a request response for service 2 to the terminal device.

[0232] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more network node adaptation device embodiments provided below can refer to the limitations of the network node adaptation method above, and will not be repeated here.

[0234] In an exemplary embodiment, as Figure 10 shown, a network node adaptation device is provided. This device is applied to a terminal device.
