[0100] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0101] In order to better understand the network node selection method, device, equipment, system and storage medium provided by this application, the application scenario of this application is first introduced.

[0102] A key trend in the development of sixth-generation wireless systems (6G) networks is a decentralized network architecture that combines centralized and distributed systems. The network architecture of fifth-generation wireless systems (5G) and previous generations of communication technologies is centralized, with core network equipment rooms deployed based on demand and enabling the centralized deployment of core network functions. With the development of networks, driven by both business scenarios and technological advancements, the design of 6G network architectures must consider a distributed network architecture, with control systems gradually evolving towards a distributed approach. With the distributed development of intelligence and cloud computing, new connections and networks will also require distributed deployment.

[0103] 6G will address diverse scenarios and network requirements in the air, space, land, and sea. A centralized network architecture cannot uniformly meet all scenarios. To address this challenge, the 6G network architecture needs to move beyond centralized control and gradually evolve toward a distributed network architecture, extending more network functions to the network edge and establishing distributed, homogeneous small cloud units (SCUs) with varying levels of functionality. Each SCU is self-contained and has complete control and data forwarding capabilities. Multiple SCUs can form autonomous micro-networks based on business needs, providing targeted network services based on specific business scenarios, user scale, geographic environment, and other requirements. These SCUs, also known as distributed network nodes, represent a customized or fully functional core network. These distributed network nodes are managed and controlled by a centralized network node.

[0104] Figure 1 is a schematic diagram of a network structure provided in an embodiment of the present application; Figure 1 As shown, the network structure may include UE, AN device, and distributed network. The communication between UE and AN device may include uplink communication (i.e., communication from UE to AN device) and downlink communication (i.e., communication from AN device to UE). In uplink communication, UE is used to send uplink signals to AN device; AN device is used to receive uplink signals from UE. In downlink communication, AN device is used to send downlink signals to UE; UE is used to receive downlink signals from AN device. The distributed network communicates with AN device. The distributed network includes multiple distributed network nodes. The distributed network nodes in the distributed network will be under the control of AN device.

[0105] UE can be a device that provides voice and / or data connectivity to users, a handheld device with wireless connection function, or other processing equipment connected to a wireless modem. UE can also be called terminal equipment, mobile station (MS), mobile terminal (MT), etc. Figure 1 As shown, according to different ways in which user equipment access the network, user equipment can be divided into: land access equipment, underground access equipment, deep space access equipment, satellite access equipment, underwater access equipment, etc. Furthermore, the user equipment can be a handheld terminal, customer premises equipment (CPE) laptop computer, subscriber unit, cellular phone, smart phone, wireless data card, personal digital assistant (PDA) computer, tablet computer, wireless modem, handheld device, laptop computer, session initiation protocol (SIP) phone, cordless phone or wireless local loop (WLL) station, machine type communication (MTC) terminal, wearable device (such as smart watch, smart bracelet, pedometer, etc.), vehicle-mounted equipment (such as car, bicycle, electric car, airplane, ship, train, high-speed rail, etc.), virtual reality (VR) device, augmented reality (AR) device, etc. The wireless terminals can be used in various fields, such as augmented reality (AR) devices, wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, and electric meters), intelligent robots, workshop equipment, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, flying equipment (such as intelligent robots, hot air balloons, drones, and airplanes), and other devices that can access the Internet.

[0106] AN equipment, also known as radio access network (RAN) equipment, provides wireless access for terminal devices. It is primarily responsible for air interface functions such as radio resource management, quality of service (QoS) flow management, data compression and encryption, etc. Access network equipment can include various types of base stations, such as macro base stations, micro base stations (also known as small base stations), relay stations, and access points. Access network equipment may also include evolved Node B (eNB or eNodeB) in long term evolution (LTE); or base station gNB in ​​5G network or base station in future evolved public land mobile network (PLMN), broadband network service gateway (BNG), aggregation switch or non-third generation partnership project (3GPP) access equipment, etc., wireless fidelity (WiFi) access node (access point, transmitting and receiving point (TRP), transmitting point (TP), mobile switching center and device to device (D2D), vehicle to everything (V2X), machine to machine (M2M) communication. Equipment that assumes the base station function, etc.

[0107] The distributed network 13 includes multiple distributed network nodes. A distributed network node refers to a core network that is customized on demand or fully functional and can provide services to user equipment. In a 6G or next-generation communication system, one or more network elements, devices or entities that can provide services to terminal equipment.

[0108] It should be noted that Figure 1 The network architecture shown is not limited to including only the UE, AN devices and distributed networks shown in the figure, but may also include other UEs, AN devices and distributed networks not shown in the figure, which will not be listed one by one in this application.

[0109] The technical solution of the present application can be applied to cellular systems related to the Third Generation Partnership Project (3GPP), such as 6G communication systems, and can also be applied to wireless fidelity (WiFi) systems, communication systems that support the integration of multiple wireless technologies, or future-oriented evolution systems.

[0110] like Figure 1 As shown, the distributed network includes multiple distributed network nodes. Therefore, it is necessary to select an appropriate distributed network node in the distributed network based on the UE information to allow the UE to access the network and provide network services for the UE. Currently, the commonly used network node selection methods mainly include the following three methods.

[0111] (1) Select network nodes based on configured and contracted network node information

[0112] The network nodes allowed to be accessed, the default network nodes, and the subscribed network nodes are configured in the UE and subscription data functions respectively. When the UE accesses the network, the corresponding network node is selected based on the network node information carried by the UE or the subscribed network node information to access the network.

[0113] (2) Selecting a network node based on Network Attached Storage (NAS) messages

[0114] Assuming the UE has successfully registered with the network, when the UE sends an NAS message to one or more network nodes, in addition to the NAS message, it also needs to carry other parameters for the RAN to select an appropriate network node. These other parameters include, but are not limited to, network node identifiers, UE identifiers, and session identifiers.

[0115] (3) Selecting network nodes based on UE routing strategy

[0116] In a distributed network cross-domain scenario, when the policy control function (PCF) issues the UE routing policy, the routing description adds the location of the data network name (DNN), that is, the network node identifier to which the DNN belongs. When the UE initiates a session establishment, the network node to which the DNN belongs is carried in the radio resource control (RRC) message or the NAS message to assist the AN device or the access management function or session management function of the current service to determine the appropriate session management function. When multiple network nodes appear, a network node that provides services to the UE is determined based on other valid information.

[0117] The three network node selection methods described above only consider the network node's "connectivity" services and fail to consider the UE's own capabilities or service requirements. In a distributed network scenario, the service area of ​​each distributed network node is limited and customized. Distributed network nodes are heterogeneous, providing different capabilities. Furthermore, UEs' network requirements are no longer limited to "connectivity" services; they may require new services such as computing power and AI. 6G networks offer not only "connectivity" services but also "computing power," "computing," and "data" services. UEs are also heterogeneous. For example, some UEs are computing nodes, others have data service capabilities, and others may provide intelligence-related capabilities. Therefore, UEs with different capabilities and / or service requirements require services from distributed network nodes that match their capabilities and / or service requirements. The question is how to select the appropriate distributed network node based on UE needs to achieve "precise" on-demand services and maximize network resource utilization.

[0118] To solve the above technical problems, embodiments of the present application provide a network selection method, device, apparatus, system, and storage medium, wherein a UE sends a first message to an access network device, where the first message includes UE capability information and / or UE service requirement information; after receiving the first message, the access network device determines a first distributed network node in the distributed network based on the UE capability information and / or UE service requirement information, and sends a registration request message to the first distributed network node; after receiving the registration request message, the first distributed network node determines a first target network node in the distributed network based on the UE capability information and / or UE service requirement information, and sends a second message to the UE; the second message includes attribute information of the first target network node; after receiving the second message, the UE accesses the first target network node according to the attribute information of the first target network node.

[0119] Since the first distributed network node is selected by the access network device based on the UE capability information and / or the UE service requirement information, and the first target network node is selected by the first distributed network node based on the UE capability information and / or the UE service requirement information, the first target network node accessed by the UE is selected on demand through the access network device and the first distributed network node, and a suitable network node is matched for the UE, thereby enabling the network node to provide services accurately on demand and maximize network resource utilization.

[0120] Figure 2 This is a flow chart of a method for selecting a network node by a UE according to the present application; Figure 2 , from the perspective of UE, the process of the network node selection method is explained.

[0121] like Figure 2 As shown, the network node selection method provided in the embodiment of the present application mainly includes steps S101 to S103.

[0122] S101. Send a first message to an AN device, where the first message includes UE capability information and / or UE service requirement information, wherein the first message is used to instruct the AN device to select a first distributed network node that matches the UE capability information and / or UE service requirement information.

[0123] The first message is a registration request sent by the UE to the AN device, and the registration request includes UE capability information and / or UE service requirement information.

[0124] UE capabilities refer to the capabilities possessed by the UE, such as the data service capabilities and intelligence-related capabilities possessed by the UE. UE capability information refers to the relevant information used to characterize the capabilities possessed by the UE. Exemplarily, UE capability information includes one or more of the following: UE capability type, UE capability priority, UE capability usage time, and UE capability usage location; UE capability type includes one or more of the following: computing power, artificial intelligence (AI) model, AI algorithm, and data service.

[0125] UE service requirements refer to the UE's requirements for network services. UE service requirement information refers to information that characterizes the UE's requirements for network services. Exemplarily, UE service requirement information includes one or more of the following: UE service type, UE service requirement priority, UE service requirement usage time, and UE service requirement usage location; UE service type includes one or more of the following: computing power service, computing service, and data service.

[0126] In the case where the UE only needs to access a network node that matches the UE capabilities, the first message only includes UE capability information; in the case where the UE only needs to access a network node that matches the UE service requirements, the first message only includes UE service requirement information; in the case where the UE needs to access a network node that matches both the UE capabilities and the UE service requirements, the first message includes UE capability information and UE service requirement information.

[0127] There are multiple distributed network nodes in the distributed network, and the first distributed network node and the first target network node are both distributed network nodes in the distributed network. Furthermore, the first distributed network node is a distributed network node selected by the AN device from the multiple distributed network nodes that matches the UE capability information and / or UE service requirement information. The first target network node is a distributed network node selected by the first distributed network node from the multiple distributed network nodes that matches the UE capability information and / or UE service requirement information.

[0128] In the process of the UE applying for registration with the network, the UE encapsulates the UE capability information and / or UE service requirement information in the AN parameters, encapsulates the UE capability information and / or UE service requirement information in the registration request message, and adds the AN parameters and the registration request message to the first message. The UE sends a first message to the AN device. After receiving the first message, the AN device selects a first distributed network node that matches the UE capability information and / or UE service requirement information based on the UE capability information and / or UE service requirement information in the AN parameters. After the AN device selects the first distributed network node, it sends a registration request message to the first distributed network node. After receiving the registration request message, the first distributed network node selects a first target network node that matches the UE capability information and / or UE service requirement information. After the first distributed network node selects the first target network node, it encapsulates the attribute information of the first target network node in the second message. The first distributed network sends a second message to the UE.

[0129] S102: Receive a second message sent by a first distributed network node, where the second message includes attribute information of a first target network node.

[0130] The first target network node is a distributed network node selected by the first distributed network that matches the UE capability information and / or UE service requirement information. Further, the first target network node may be the first distributed network node that matches the UE capability information and / or UE service requirement information, or may be a second distributed network node selected by the first distributed network node from other distributed network nodes in the distributed network that matches the UE capability information and / or UE service requirement information.

[0131] After determining the first target network node, the first distributed network node encapsulates the attribute information of the first target network node in a second message, and transparently transmits the second message to the UE through the AN device.

[0132] The UE receives the second message sent by the first distributed network node, which mainly includes the following four situations.

[0133] (1) When the first target network node is a first distributed network node, a registration acceptance message sent by the first distributed network node is received, where the registration acceptance message includes attribute information of the first distributed network node.

[0134] The first distributed network node finds that it can provide services for the UE based on its own capability information and / or the service information it provides. The first distributed network node then uses itself as the first target network node. At this time, the first distributed network node encapsulates its own attribute information in a registration acceptance message, and transparently transmits the registration acceptance message to the UE through the AN device. The UE receives the registration acceptance message transparently transmitted through the AN device.

[0135] (2) When the first target network node is the second distributed network node, a registration acceptance message sent by the first distributed network node is received, where the registration acceptance message includes attribute information of the second distributed network node, wherein the second distributed network node is determined by the first distributed network node based on the UE capability information and / or the UE service requirement information.

[0136] Based on its own capability information and / or service information, the first distributed network node discovers that it cannot provide services to the UE. The first distributed network node then reselects a second distributed network node that can provide services to the UE from other distributed network nodes in the distributed network as the first target network node. The first distributed network node then encapsulates the attribute information of the second distributed network node in a registration accept message, transparently transmits the registration accept message to the UE via the AN device, and the UE receives the registration accept message transparently transmitted via the AN device.

[0137] (3) When the first target network node is the second distributed network node, a UE policy message is received from the first distributed network node, where the UE policy message includes attribute information of the second distributed network node, wherein the second distributed network node is determined by the first distributed network node based on the UE capability information and / or the UE service requirement information.

[0138] The first distributed network node finds that it cannot provide services for the UE based on its own capability information and / or the service information it provides. The first distributed network node reselects a second distributed network node that can provide services for the UE as the first target network node from other distributed network nodes in the distributed network.

[0139] The first distributed network node transparently transmits a registration acceptance message to the UE through the AN device, and the registration acceptance message does not include the attribute information of the first target network node. After receiving the registration acceptance message, the UE determines that the first distributed network node receives the UE's registration request. Then, the first distributed network node encapsulates the attribute information of the second distributed network node in a UE policy message, and transparently transmits the UE Policy message to the UE through the AN device. The UE Policy message can be a user equipment routing selection policy (URSP) message, that is, the attribute information of the second distributed network node is encapsulated in the URSP message, and the first distributed network node transmits the attribute information of the second distributed network node through the URSP message.

[0140] After receiving the UE policy message, the UE updates the UE policy based on the UE policy message, and sends a response message corresponding to the UE policy message to the first target network node if the UE supports processing the UE policy.

[0141] In a specific implementation, since it is necessary to add attribute information of the second distributed network node that the UE is allowed to access, the policy control function (PCF) entity in the first distributed network node is triggered to decide to update the UE policy. The PCF entity encapsulates the attribute information of the second distributed network node in a UE policy message, and the PCF entity sends the UE policy message to the access control management function (AMF) entity, and the AMF entity transparently transmits the UE policy message to the UE. After the UE receives the UE policy provided by the PCF entity, the UE supports processing the attribute information of the newly added second distributed network node and sends the result of whether the processing is supported to the AMF entity. The AMF entity sends a response message to the PCF entity.

[0142] (4) When the first target network node is the second distributed network node, a UE configuration update command message sent by the first distributed network node is received, where the UE configuration update command message includes attribute information of the second distributed network node, wherein the second distributed network node is determined by the first distributed network node based on the UE capability information and / or the UE service requirement information.

[0143] The first distributed network node finds that it cannot provide services for the UE based on its own capability information and / or the service information it provides. The first distributed network node reselects a second distributed network node that can provide services for the UE from other distributed network nodes in the distributed network node as the first target network node.

[0144] The first distributed network node transparently transmits a registration accept message to the UE via the AN device. The registration accept message does not include attribute information of the first target network node. After receiving the registration accept message, the UE determines that the first distributed network node has accepted the UE's registration request. The first distributed network node then encapsulates the attribute information of the second distributed network node in a UE Configuration Update Command message and transparently transmits the UE Configuration Update Command message to the UE via the AN device.

[0145] After receiving the UE configuration update command message, the UE performs configuration update based on the UE configuration update instruction; if the configuration update is successful, a configuration update success message is sent to the first target network node.

[0146] In one specific implementation, the AMF entity decides to initiate a UE configuration change due to, for example, a change in a distributed network node accessible to the UE. The AMF entity sends a UE Configuration Update Command message to the UE, including parameters such as a Configuration Update Indication and attributes of a second accessible distributed network node. Upon successful configuration, the UE returns a completion confirmation message.

[0147] S103: Access the first target network node according to the attribute information of the first target network node.

[0148] After receiving the second message, the UE parses the attribute information of the first target network node from the second message and accesses the first target network node based on the attribute information of the first target network node. If the first target network node is the first distributed network node, the UE accesses the first distributed network node; if the first target network node is the second distributed network node, the UE accesses the second distributed network node.

[0149] In one possible implementation, after the UE accesses the first target network node, the UE may establish a service with the first target network node. Specifically, the UE sends a service requirement request message to the first target network node; the service requirement request message is used to instruct the first target network node to determine a second target network node based on the UE startup capability information and / or the UE service requirement information, and the second target network node is used to provide network services for the UE.

[0150] The UE startup capability information and / or the UE service requirement information is encapsulated in the service requirement request message; or the UE startup capability information and / or the UE service requirement information is stored in the first target network node.

[0151] When the second target network node is the first target network node, the first target network node is used to provide network services for the UE; when the second target network node is a third distributed target network node, the third distributed network node provides network services for the UE by collaborating with the first target network node, wherein the third distributed network node is a network node having a collaborative relationship with the first target network node.

[0152] When UE capabilities are activated or there is a service demand request, the UE sends a service demand request message to the first target network node. The service demand request message includes information such as the UE identifier and the UE service identifier. After the first target network node receives the UE's service demand request message, if the service demand request message includes UE activation capability information or UE service demand request information, the first target network node determines whether the current UE requirements can be met. If so, it provides network services to the UE by itself; if not, the second target network node provides network services to the UE through collaboration.

[0153] In one possible implementation embodiment, after the UE accesses the first target network node, the UE capability information and / or UE service requirement information of the UE may be updated over time or environment. At this time, the UE sends an update request message to the first target network node, where the update request message includes the updated UE capability information and / or the updated UE service requirement information; wherein the update request message is used to instruct the first target network node to select a third target network node that matches the updated UE capability information and / or the updated UE service requirement information; receive a third message sent by the first target network node, where the third message includes attribute information of the third target network node; and access the third target network node based on the attribute information of the third target network node.

[0154] The third target network node is a matching distributed network node that is reselected by the first target network node based on the updated UE capability information and / or the updated UE service requirement information.

[0155] In an embodiment of the present application, when UE capability information and / or UE service requirement information is updated, the UE sends an update request message to the first target network node, where the update request message carries the updated UE capability information and / or the updated UE service requirement information. After receiving the update request message, the first target network node selects a third target network node that matches the updated UE capability information and / or the updated UE service requirement information based on the updated UE capability information and / or the updated UE service requirement information.

[0156] The first target network node sends the attribute information of the third target network node to the UE, and the UE re-accesses the third target network node according to the attribute information of the third target network node.

[0157] It should be noted that the process of the UE receiving the third message sent by the first target network node is the same as the process of the UE receiving the second message sent by the first distributed network node. For details, please refer to the description in the above embodiment, and the embodiments of this application will not be repeated.

[0158] It should be noted that after the UE updates the UE capability information and / or UE service requirement information, it may access a third target network node. The process of the UE conducting business requirements with the third target network node is the same as the process of the UE conducting business requirements with the first target network node. For details, please refer to the description in the above embodiment.

[0159] Figure 3 This is a flow chart of a method for selecting a network node by an AN device according to the present application; Figure 3 , in the embodiment of the present disclosure, the process of the network node selection method is described from the perspective of the AN device.

[0160] like Figure 3 As shown, the network node selection method provided in the embodiment of the present application mainly includes steps S201 to S203.

[0161] S201. Receive a first message sent by a UE, where the first message includes UE capability information and / or UE service requirement information.

[0162] UE capabilities refer to the capabilities possessed by the UE, such as the data service capabilities and intelligence-related capabilities possessed by the UE. UE capability information refers to the relevant information used to characterize the capabilities possessed by the UE. Exemplarily, UE capability information includes one or more of the following: UE capability type, UE capability priority, UE capability usage time, and UE capability usage location; UE capability type includes one or more of the following: computing power, artificial intelligence (AI) model, AI algorithm, and data service.

[0163] UE service requirements refer to the UE's requirements for network services. UE service requirement information refers to information that characterizes the UE's requirements for network services. Exemplarily, UE service requirement information includes one or more of the following: UE service type, UE service requirement priority, UE service requirement usage time, and UE service requirement usage location; UE service type includes one or more of the following: computing power service, computing service, and data service.

[0164] The first message includes AN parameters and a registration request message. The AN parameters include a registration reason, as well as UE capability information and / or UE service requirement information. The registration request message includes a registration type, a UE identifier, and UE capability information and / or UE service requirement information. The registration reason indicates the reason why the AN device UE is requesting network access.

[0165] In the process of a UE applying to register with a network, the UE sends a first message to an AN device, and the AN device receives the first message sent by the UE. Specifically, in the process of a UE applying to register with a network, the UE sends a registration request to the AN device, and the AN device receives the registration request sent by the UE. The registration request includes: AN parameters and a registration request message.

[0166] S302: Determine a first distributed network node in the distributed network based on UE capability information and / or UE service requirement information.

[0167] After receiving the AN parameters, the AN device selects a first distributed network node from the distributed network based on the UE capability information and / or UE service requirement information in the AN parameters. The AN device may obtain or locally store configuration information for each distributed network node in the distributed network. This configuration information includes information about the capabilities of the distributed network nodes and information about the services provided by the distributed network nodes.

[0168] The AN device determines the first distributed network node in the following three situations:

[0169] (1) The AN device selects the first distributed network node that matches the UE capability information from the distributed network

[0170] The AN device can obtain capability information of each distributed network node in the distributed network. The AN device matches the capability information of the distributed network node with the UE capability information. If the match is successful, the distributed network node is used as the first distributed network node. If the match fails, the capability information of other distributed network nodes in the distributed network is matched with the UE capability information until it is determined that the capability information of the distributed network node successfully matches the UE capability information, and the distributed network node is used as the first distributed network node.

[0171] For example: if the UE capability type included in the UE capability information is intelligence-related capability, and the distributed network node has the intelligence-related capability, the match is successful; if the UE capability type included in the UE capability information is intelligence-related capability, and the distributed network node does not have the intelligence-related capability, the match fails.

[0172] For another example: if the UE capability priority included in the UE capability information is high priority and the capability priority of the distributed network node is high priority, the match is successful; if the UE capability priority included in the UE capability information is high priority and the capability priority of the distributed network node is low, the match fails.

[0173] For example: if the UE capability usage location included in the UE capability information is location A, and the distributed network node's capability usage location is location A, the match is successful; if the UE capability usage location included in the UE capability information is location A, and the distributed network node's capability usage location is location B, the match fails.

[0174] For example: if the UE capability usage time included in the UE capability information is from 8 pm to 10 pm, and the distributed network node has the capability usage time from 8 pm to 10 pm, the match is successful; if the UE capability usage time included in the UE capability information is from 8 pm to 10 pm, and the distributed network node has the capability usage time from 8 am to 10 am, the match fails.

[0175] It should be noted that since the UE capability information includes multiple pieces of information, when each piece of information in the capability information possessed by the distributed network node is successfully matched with the information included in the UE capability information, it is determined that the capability information possessed by the distributed network node is successfully matched with the UE capability information; when any piece of information in the capability information possessed by the distributed network node fails to match the information included in the UE capability information, it is determined that the capability information possessed by the distributed network node is successfully matched with the UE capability information.

[0176] (2) The AN device selects the first distributed network node that matches the UE service requirement information from the distributed network

[0177] The AN device can obtain service information provided by each distributed network node in the distributed network. The AN device matches the service information provided by the distributed network node with the UE service requirement information. If the match is successful, the distributed network node is used as the first distributed network node. If the match fails, the service information provided by other distributed network nodes in the distributed network is matched with the UE service requirement information until it is determined that the service information provided by the distributed network node successfully matches the UE service requirement information, and the distributed network node is used as the first distributed network node.

[0178] For example, if the UE service type included in the UE service requirement information is computing service and the distributed network node can provide computing service, the matching is successful; if the UE service type included in the UE service requirement information is computing service and the distributed network node cannot provide computing service, the matching fails.

[0179] For example: if the UE service requirement priority included in the UE service requirement information is high priority and the service priority provided by the distributed network node is high priority, the match is successful; if the UE service requirement priority included in the UE service requirement information is high priority and the service priority provided by the distributed network node is low priority, the match fails.

[0180] For example: if the UE service requirement usage location included in the UE service requirement information is location A, and the service usage location provided by the distributed network node is location A, the match is successful; if the UE service requirement usage location included in the UE service requirement information is location A, and the service usage location provided by the distributed network node is location B, the match fails.

[0181] For example: if the UE service demand usage time included in the UE service demand information is from 11pm to 12am, and the distributed network node has the capability to use it from 11pm to 12am, the match is successful; if the UE service demand usage time included in the UE service demand information is from 11pm to 12am, and the distributed network node has the capability to use it from 8am to 10am, the match fails.

[0182] It should be noted that since the UE service requirement information includes multiple pieces of information, when each piece of information in the capability information of the distributed network node is successfully matched with the information included in the UE service requirement information, it is determined that the capability information of the distributed network node is successfully matched with the UE service requirement information; when any piece of information in the capability information of the distributed network node fails to match the information included in the UE service requirement information, it is determined that the capability information of the distributed network node is successfully matched with the UE service requirement information.

[0183] (3) The AN device selects the first distributed network node from the distributed network that matches both the UE capability information and the UE service requirement information.

[0184] When the AN parameters include both UE capability information and UE service requirement information, the AN device selects a first distributed network node from the distributed network that matches both the UE capability information and the UE service requirement information. Only in this way can the selected first distributed network node meet the requirements.

[0185] It should be noted that the embodiment of the present application provides a method for the AN device to select the first distributed network node based on UE capability information and / or the UE service requirement information. In actual environments, the AN device can also select the first distributed network node based on other parameters (e.g., UE identity) or other policies.

[0186] S303. Send a registration request message to the first distributed network node, where the registration request message includes UE capability information and / or UE service requirement information, and the registration request message is used to instruct the first distributed network node to select a first target network node that matches the UE capability information and / or UE service requirement information.

[0187] After the AN device determines the first distributed network node, the AN device sends a registration request message to the first distributed network node. The registration request message includes UE capability information and / or UE service requirement information. After receiving the registration request message, the first distributed network node selects a first target network node that matches the UE capability information and / or UE service requirement information. The first distributed network node sends attribute information of the first target network node to the UE, and the UE can access the first target network node based on the attribute information.

[0188] Furthermore, after the AN device determines the first distributed network node, it also sends the UE location to the first distributed network node, so that the first distributed network node can know the current location of the UE.

[0189] In this embodiment of the present application, after receiving the first message, the AN device selects a first distributed network node from the distributed network that matches the UE capability information and / or UE service requirement information, and sends a registration request message to the first distributed network node. Because the first distributed network node is selected by the access network device based on the UE capability information and / or UE service requirement information, a suitable network node is matched to the UE, enabling the network node to provide services accurately and on demand and maximize network resource utilization.

[0190] Figure 4 This is a flow chart of a distributed network node executing a network node selection method provided by the present application; Figure 4 In the embodiment of the present disclosure, the process of the network node selection method is described from the perspective of the first distributed network node. The first distributed network node is a network node in the distributed network selected by the AN device that matches the UE capability information and / or UE service requirement information.

[0191] like Figure 4 As shown, the network node selection method provided in the embodiment of the present application mainly includes steps S301 to S303.

[0192] S301: Receive a registration request message sent by an AN device, where the registration request message includes UE capability information and / or UE service requirement information.

[0193] After the AN device selects a first distributed network node that matches the UE capability information and / or UE service requirement information from the distributed network, the AN device sends a registration request message to the first distributed network node, where the registration request message includes the UE capability information and / or UE service requirement information.

[0194] S302: Determine a first target network node in the distributed network based on UE capability information and / or UE service requirement information.

[0195] The first target network node refers to a distributed network node selected by the first distributed network node and matching the UE capability information and / or UE service requirement information, wherein the first target network node is a network node that the UE is allowed to visit or access.

[0196] After receiving the registration request message, the first distributed network node determines whether it can provide services for the UE. If it can provide services for the UE, the first distributed network node serves as the first target network node and allows the UE to access or connect to the first distributed network node. If the first distributed network node cannot provide services for the UE, the first distributed network node selects another second distributed network node that can provide services for the UE from the distributed network as the first target node and allows the UE to access or connect to the second distributed network node.

[0197] In one implementation, the first distributed network matches its own capability information and / or provided service information with UE capability information and / or UE service requirement information; if the match is successful, the first distributed network node is determined as the first target network node.

[0198] The process of the first distributed network node matching its own information with the UE capability information and / or UE service requirement information is the same as the process of the AN device matching the capability information and / or provided service information of the distributed network node with the UE capability information and / or UE service requirement information. For details, please refer to the description in the above embodiments.

[0199] In another implementation, if the capability information possessed by the first distributed network node and / or the service information provided fails to match the UE capability information and / or the UE service requirement information, the capability information possessed by other distributed network nodes in the distributed network and / or the service information provided are matched with the UE capability information and / or the UE service requirement information; and the second distributed network node that successfully matches is determined as the first target network node.

[0200] The process of the first distributed network node matching the capability information and / or service information provided by other distributed network nodes in the distributed network with the UE capability information and / or UE service requirement information is the same as the process of the AN device matching the capability information and / or service information provided by the distributed network node with the UE capability information and / or UE service requirement information. For details, please refer to the description in the above embodiments.

[0201] S303: Send a second message to the UE, where the second message includes attribute information of the first target network node, and the attribute information of the first target network node is used to instruct the UE to access the first target network node.

[0202] After the first distributed network node determines the first target network node, it encapsulates the attribute information of the first target network node in a second message, and sends the second message to the UE.

[0203] The first distributed network node sending the second message to the UE mainly includes the following four situations:

[0204] (1) When the first distributed network node is the first target network node, the first distributed network node sends a registration acceptance message to the UE, where the registration acceptance message includes attribute information of the first distributed network node, wherein the attribute information of the first distributed network node is used to instruct the UE to access the first distributed network node.

[0205] (2) When the second distributed network node is the first target network node, the first distributed network node sends a registration acceptance message to the UE, where the registration acceptance message includes attribute information of the second distributed network node, wherein the attribute information of the second distributed network node is used to instruct the UE to access the second distributed network node.

[0206] (3) When the second distributed network node is the first target network node, the first distributed network node sends a UE policy message to the UE, where the UE policy message includes attribute information of the second distributed network node, where the attribute information of the second distributed network node is used to instruct the UE to access the second distributed network node.

[0207] (4) When the second distributed network node is the first target network node, the first distributed network node sends a UE configuration update command message to the UE, where the UE configuration update command message includes attribute information of the second distributed network node, wherein the attribute information of the second distributed network node is used to instruct the UE to access the second distributed network node.

[0208] The specific description of the four situations can refer to the description on the UE side and will not be repeated in the embodiments of this application.

[0209] In the following embodiment, when the first distributed network node is used as the first target network node, the service demand request process and update request process on the network side are introduced.

[0210] After the UE accesses the first target network node using the attribute information of the first target network node, the UE can establish a service with the first target network node. The UE sends a service demand request message to the first target network node, and the first target network node receives the service demand request message sent by the UE; obtains UE startup capability information and / or UE service demand information; and in response to an instruction in the service demand request message, determines a second target network node based on the UE startup capability information and / or the UE service demand information, and the second target network node is used to provide network services for the UE.

[0211] In the case where the service requirement request message includes UE startup capability information and / or UE service requirement information, obtain the UE startup capability information and / or UE service requirement information included in the service requirement request message; in the case where the service requirement request message does not include UE startup capability information and / or UE service requirement information, obtain the UE startup capability information and / or UE service requirement information saved in the first target network node.

[0212] In one implementation, the first target network node determines whether the first target network node's own capability and / or its own service demand situation meets the UE startup capability information and / or UE service demand information; if the first target network node's own capability and / or its own service demand situation meets the UE startup capability information and / or UE service demand information, the first target network node is determined as the second target network node, and the first target network node provides network services for the UE.

[0213] In another implementation, if the first target network node's own capabilities and / or its own service requirements do not meet the UE startup capability information and / or UE service requirement information, a third distributed network node that has a collaborative relationship with the first target network node will be used as the second target network node, wherein the third distributed network node provides network services to the UE by collaborating with the first target network node.

[0214] When the UE capability is activated or there is a service demand request, a service demand request message is sent to the first target network node. The service demand request message includes information such as the UE identifier and the UE service identifier. After the first target network node receives the service demand request message from the UE, if the service demand request message includes UE activation capability information or UE service demand request information, the first target network node determines whether the current UE demand can be met. If so, the first target network node will serve the UE itself; if not, the second target network node will provide services to the UE through collaboration.

[0215] The second target network node provides services to the UE mainly in the following three situations.

[0216] (1) The first target network node's own capability situation and / or its own service demand situation include: the capability priority being served by the first target network and / or the service demand priority being served; the UE startup capability information and / or UE service demand information include: the UE startup capability priority and / or the UE service demand priority; the first target network node's own capability situation and / or its own service demand situation do not meet the UE startup capability information and / or the UE service demand information, including: the capability priority being served by the first target network and / or the service demand priority being served are higher than the UE startup capability priority and / or the UE service demand priority.

[0217] The first target network node is providing services for high-priority capabilities or business needs and selects the corresponding distributed network node. If, at this time, the service corresponding to the business demand request sent by the UE to the first target network node is a low-priority scenario, the business is migrated to the collaborative second network node through collaboration between the distributed network nodes for service.

[0218] (2) The first target network node's own capability status and / or its own service demand status include: the capability usage time being served by the first target network and / or the service demand usage time being served; the UE startup capability information and / or UE service demand information include: the UE startup capability usage time and / or the UE service demand usage time; the first target network node's own capability status and / or its own service demand status do not meet the UE startup capability information and / or UE service demand information, including: the capability usage time being served by the first target network and / or the service demand usage time being served is greater than the UE startup capability usage time and / or the UE service demand usage time.

[0219] The first target network node is providing services for capabilities or business needs with long usage time, and selects the corresponding distributed network node. If at this time, the service corresponding to the business demand request sent by the UE to the first target network node is a scenario with short usage time, the business is migrated to the collaborative second network node through collaboration between the distributed network nodes for service.

[0220] (3) The first target network node's own capability situation and / or its own business demand situation include: the capability usage location being served by the first target network and / or the business demand usage location being served; the UE startup capability information and / or UE business demand information include: the UE startup capability usage location and / or the UE business demand usage location; the first target network node's own capability situation and / or its own business demand situation do not meet the UE startup capability information and / or UE business demand information, including: the capability usage location being served by the first target network and / or the business demand usage location being served are consistent with the UE startup capability usage location and / or the UE business demand usage location.

[0221] The first target network node is providing services for capabilities or business needs using the current location, and selects the corresponding distributed network node. If, at this time, the UE sends a service request corresponding to the business need to the first target network node, the business is migrated to the collaborative second network node through collaboration between the distributed network nodes for service.

[0222] After the UE accesses the first target network node, the UE capability information and / or UE service requirement information of the UE may be updated over time or in response to the environment. At this time, the UE sends an update request message to the first target network node, and the first target network node receives the update request message sent by the UE; the update request message includes the updated UE capability information and / or the updated UE service requirement information; the first target network node determines a third target network node based on the updated UE capability information and / or the updated UE service requirement information; the first target network node sends a third message to the UE, wherein the third message includes attribute information of the third target network node, wherein the attribute information of the third target network node is used to instruct the UE to access the third target network node.

[0223] The process of the first target network node determining the third target network node based on the updated UE capability information and / or the updated UE service requirement information is the same as the process of the first distributed network node determining the first target network node based on the UE capability information and / or the UE service requirement information. For details, please refer to the description in the above embodiment.

[0224] It should be noted that the process of the third target network node sending the third message to the UE is the same as the process of the first target network node sending the second message to the UE. For details, please refer to the description in the above embodiment, and the embodiments of this application will not be repeated here.

[0225] It should be noted that after the UE updates the UE capability information and / or UE service requirement information, it may access a third target network node. The process of the UE conducting business requirements with the third target network node is the same as the process of the UE conducting business requirements with the first target network node. For details, please refer to the description in the above embodiment.

[0226] When the second distributed network node acts as the first target network node, the service demand request process and update request process executed on the network side are the same as the service demand request process and update request process on the network side when the first distributed network node acts as the first target network node. For details, please refer to the description in the above embodiment, and the embodiments of this application will not be repeated here.

[0227] In a specific implementation, an interactive method for selecting a network node during a registration process is provided, such as Figure 5 As shown, the interactive method for selecting a network node during the registration process mainly includes the following steps:

[0228] S401. UE sends a registration request to AN equipment.

[0229] The information carried in the registration request includes AN parameters and a Registration Request message. The AN parameters include information such as the registration reason, UE capability information and / or UE service requirements; the Registration Request message includes information such as the registration type, UE identifier, UE capability information and / or UE service requirements; the UE capability information includes a list of capability types (not limited to computing power, AI models, AI algorithms, data services, etc.), UE capability priority, UE capability usage time, UE capability usage location, etc.; the UE service requirement information includes information such as the UE service requirement type (not limited to computing power, computing, data services, etc.), UE service requirement priority, UE service requirement usage time, and UE service requirement usage location.

[0230] S402: The AN device selects a network node and selects a first distributed network node.

[0231] Since the AN parameters include UE capability information and / or UE service requirements, the AN device selects a first distributed network node that matches the UE capability information and / or UE service requirements. Specific selection methods can refer to the description in the above embodiments.

[0232] S403. The AN device sends a registration request message to the first distributed network node.

[0233] After the AN device selects the first distributed network node, the AN device sends a registration request to the first distributed network node. The registration request carries information such as a Registration Request message and a UE location.

[0234] S404: The first distributed network node reselects a network node based on the registration request message and selects a first target network node.

[0235] After the first distributed network node receives the registration request, since the registration request carries UE capability information and / or UE service requirements, the first distributed network node determines whether its own capability information and / or provided services can meet the UE capability information and / or UE service requirements. If so, it indicates that the first distributed network node can provide services for the UE, and the first distributed network node is used as the first target network node to provide services for the UE.

[0236] If the capability information and / or provided services of the first distributed network node itself cannot meet the UE capability information and / or UE service requirements, a second distributed network node that matches the UE capability information and / or UE service requirements is selected from other distributed network nodes in the distributed network as the first target network node to provide services for the UE.

[0237] S405. The first distributed network node sends a second message to the UE.

[0238] After determining the first target network node, the first distributed network node encapsulates the attribute information of the first target network node in a second message and sends the second message to the UE, so that the UE can receive the attribute information of the first target network node.

[0239] The UE accesses the first target network node based on the attribute information of the first target network node.

[0240] It should be noted that, one of steps S406a and S406b is selected for execution according to actual conditions. When the first target network node is the first distributed network node, S406a is executed; when the first target network node is the second distributed network node, S406b is executed.

[0241] S406a: The UE accesses the first distributed network node.

[0242] In the case that the first target network node is the first distributed network node, the second message carries attribute information of the first distributed network node, and the UE accesses the first distributed network node based on the attribute information of the first distributed network node.

[0243] S406b: The UE accesses the second distributed network node.

[0244] In the case that the first target network node is the second distributed network node, the second message carries attribute information of the second distributed network node, and the UE accesses the second distributed network node based on the attribute information of the second distributed network node.

[0245] like Figure 6As shown, the first distributed network node sends the second message to the UE mainly in four ways.

[0246] In a case where the first target network node is a first distributed network node, a first method of sending a second message is performed, and the first method of sending a second message includes S51a.

[0247] S51a: The first distributed network node sends a registration accept message to the UE. The registration accept message carries attribute information of the first distributed network node.

[0248] In the case that the first target network node is the second distributed network node, any one of the following three methods is selected for execution.

[0249] The second method for sending the second message includes S52a.

[0250] S52a: The first distributed network node sends a registration accept message to the UE. The registration accept message carries attribute information of the second distributed network node.

[0251] The third method for sending the second message includes S53a and S53b.

[0252] S53a: The first distributed network node sends a registration accept message to the UE.

[0253] S53b: The first distributed network node transmits a UE policy message to the UE, where the UE policy message includes attribute information of the second distributed network node.

[0254] The fourth method of sending the second message includes S54a and S54b.

[0255] S53a: The first distributed network node sends a registration accept message to the UE.

[0256] S53b: The first distributed network node transmits a UE configuration update command message to the UE, where the UE configuration update command message includes attribute information of the second distributed network node.

[0257] Furthermore, an interactive method for selecting a network node during a service demand request is provided, such as Figure 7 As shown, the interactive method for selecting a network node during a service demand request mainly includes the following steps:

[0258] S601. A UE transparently transmits a service demand request to a first target network node through an AN device.

[0259] When the UE capability is activated or there is a service requirement request, the UE sends a service requirement request message to the first target network node. The service requirement request message includes a UE identifier, a UE service requirement identifier, UE activation capability information, UE service request information, and the like.

[0260] S602: The first target network node selects a network node based on the service demand request.

[0261] After the first target network node receives the service demand request message from the UE, if the service demand request message carries UE startup capability information or UE service demand request information, the first target network node determines whether it can meet the current UE service demand. If so, step S603a is executed. If not, steps S604a and S604b are executed.

[0262] S603a: The first target network node provides a service for the UE.

[0263] When the first target network node itself can meet the current service demand of the UE, the first target network node provides services for the UE.

[0264] S604a: The first target network node sends a service demand request to the second target network node.

[0265] S604b: The second target network node provides service to the UE in a collaborative manner.

[0266] When the first target network node itself cannot meet the current UE service demand, it sends a service demand request to the second target network node, and the second target network node provides services for the UE in a collaborative manner.

[0267] In a specific implementation, an interactive method for selecting a network node during an update request is provided, such as Figure 8 As shown, the interactive method for selecting a network node during a service demand request mainly includes the following steps:

[0268] S701. UE sends an update request message to a first target network node.

[0269] In the case that the UE capability information and / or the UE service requirement information is updated, the UE sends an update request message to the first target network node, where the update request message carries the updated UE capability information and / or the updated UE service requirement information.

[0270] S702: The first target network node selects a network node based on the update request message.

[0271] After receiving the update request message, the first target network node selects a third target network node that matches the updated UE capability information and / or the updated UE service requirement information based on the updated UE capability information and / or the updated UE service requirement information.

[0272] Other interaction processes between the UE and the first target network node are the same as the interaction processes between the UE and the first distributed network node in the above embodiment. For details, please refer to the description in the above embodiment and will not be specifically limited in this embodiment.

[0273] In a specific implementation, a method for carrying detailed attributes in a UE policy message is provided, such as Figure 9 shown.

[0274] S801. PCF decides to update UE Policy.

[0275] When it is necessary to add / update the network node attribute information available to the UE, or when a UE policy update request (ie, a network node attribute message update) is received, the PCF is triggered to decide to update the UE Policy.

[0276] S802. PCF sends the UE policy message to AMF.

[0277] S803. AMF sends the UE policy message to the UE.

[0278] The available network node attribute information is encapsulated in a UE Policy message, which is transparently transmitted by the AN device and sent to the UE. The UE Policy message can be a URSP message.

[0279] S804: The UE updates the UE policy according to the UE policy message.

[0280] S805. The UE sends the update result to the AMF.

[0281] After receiving the UE policy, the UE updates the UE policy based on the UE policy message, and sends the update result to the first target network node if the UE supports processing the UE policy.

[0282] S806. AMF sends a response message corresponding to the policy update request message to PCF.

[0283] In a specific implementation, a method for carrying detailed attributes in a UE policy message is provided, such as Figure 10 shown.

[0284] S901. AMF initiates UE configuration change.

[0285] In case of changes in the distributed network nodes accessible to the UE, the AMF initiates a UE configuration change.

[0286] S902. The AMF sends a UE configuration update command message to the UE.

[0287] The AMF sends a UE configuration update command message to the UE. The UE configuration update command message includes configuration update indication, accessible distributed network node attribute information and other parameters.

[0288] S903. The UE sends a configuration update complete message to the AMF.

[0289] After receiving the UE configuration update command message, the UE performs configuration update based on the UE configuration update instruction; if the configuration update is successful, a configuration update success message is sent to the first target network node.

[0290] See also Figure 11 , Figure 11 A schematic structural diagram of a network device 1100 provided by an exemplary embodiment of the present application is shown. Figure 11 The network device 1100 shown is used to perform operations involved in the above-mentioned network node selection method. The network device 1100 is, for example, an AN device, a first distributed network node, or a UE.

The bus can be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 11 Only one thick line is used in the diagram, but this does not mean that there is only one bus or one type of bus.
