[0002] The future trend of 6G networks is a decentralized hierarchical network with centralized and distributed collaboration. 6G networks are organized in a way of centralized and distributed collaboration and distributed autonomy. On the one hand, more network functions are extended to the network edge, and on the other hand, the core functions facing the whole are centralized. Through cloud-network integration and distributed collaboration, more complex services are supported. At the same time, the network also needs to improve the network data analysis ability and optimization strategy to adapt to the complex network environment and the changing network and service requirements.

[0155] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0156] In the embodiments of the present application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0157] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0158] The embodiments of the present application provide a data processing method and device to ensure service continuity and user experience.

[0159] Among them, the method and the device are based on the same inventive concept. Since the principles for solving problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0160] See Figure 1 , Figure 1 It is the flowchart of the data processing method provided by the embodiment of the present application, applied to the first network data function. As Figure 1 shown, it includes the following steps:

[0161] Step 101: Obtain first network data and second network data, where the first network data includes network data of the network function of the first network node corresponding to the first network data function, and the second network data includes network data of the first base station accessing the first network node.

[0162] Among them, the Network Data Function (NWDF) introduced in the network can provide specific network data services to the network. In the embodiments of the present application, through the network data functions introduced in each network node (distributed node and centralized node), the core network data in the node and the data of the base stations of the access nodes are collected and then uniformly reported to the intelligent management and control center. The intelligent management and control center globally controls the resource utilization degree, service type, network status, terminal range of services, etc. of the network nodes, so as to monitor the network and optimize the policies, and select appropriate service base stations and network nodes for the terminals.

[0163] Such as Figure 2 shown, NWDF belongs to the core network control plane network element and is connected to each control plane network element using service-based interfaces. At the same time, in the subsequent research on the service-based architecture of the Radio Access Network (RAN), NWDF can also be directly connected to the RAN through service-based interfaces.

[0164] Among them, NWDF interacts with different entities for different purposes:

[0165] Data collection based on event subscription is provided by the RAN, Access and Mobility Management Function (AMF), Session Management Function (SMF), Policy Control Function entity (PCF), Unified Data Management entity (UDM), Application Function (AF) (directly or through the Network Exposure Function (NEF)), and Operation Administration and Maintenance (OAM);

[0166] Retrieve information from the data repository (for example, the Unified Data Repository (UDR) obtains subscriber-related information through the UDM);

[0167] Retrieve information about network functions (NFs) (e.g., the Network Repository Function (NRF) for NF-related information and the Network Slice Selection Function (NSSF) for slice-related information).

[0168] Among them, the data collected by the NWDF includes, in addition to the specific data declared above, the resources of network nodes, network status, link status, and node failure problems, etc. The NWDF of a distributed node can only collect data from the RAN accessing this node. The NWDF of a centralized node can obtain the data collected by the NWDFs within each distributed node through the network interface between nodes. The NWDFs of each distributed node can obtain the data collected by the NWDFs within neighboring distributed nodes through the network interface between nodes. The processes of the NWDF registering, updating, and deregistering with the NRF can refer to the existing processes of NFs registering, updating, and deregistering with the NRF.

[0169] Set up an intelligent control center in the network. The intelligent control center is deployed above the network and can collect network data from the NWDFs of each node. Based on the collected information such as user connection, mobility management, session management, accessed services, and network conditions, the intelligent control center uses an Artificial Intelligence (AI) model to evaluate and analyze the data, optimize radio resource management and access strategies, etc., so as to perform subsequent network optimization.

[0170] In this step, the first network data function can receive a first request from the network function, where the first request includes the first network data. The first network data function can send a second request to the first base station and receive the second network data sent by the first base station.

[0171] Step 102: Send the first network data and the second network data to the intelligent control center.

[0172] After obtaining the above data, the first network data function can send the above data to the intelligent control center.

[0173] Optionally, based on this embodiment, the first network data function can also obtain updated first network data and / or updated second network data, and send the updated first network data and / or the updated second network data to the intelligent control center. Thus, in this way, the accuracy of the intelligent control center in determining node selection strategies, etc., can be ensured.

[0174] Optionally, the updated first network data and / or the updated second network data include:

[0175] Information of the first base station, where the first base station cannot provide services; or information of the first network node, where the first network node cannot provide services, so that the intelligent management and control center can select a base station or a network node and formulate a node selection strategy.

[0176] Optionally, based on this embodiment, the first network data function may further receive third network data and / or fourth network data sent by the second network data function, where the third network data includes network data of the network function of the second network node corresponding to the second network data function, and the fourth network data includes network data of the second base station accessing the second network node. Then, the first network data function may send the third network data and / or the fourth network data to the intelligent management and control center. Wherein, the first network node and the second network node are distributed nodes, or the first network node is a centralized node and the second network node is a distributed node.

[0177] In an embodiment of the present application, the first network data function may send first network data and second network data to the intelligent management and control center, where the first network data includes network data of the network function of the first network node corresponding to the first network data function, and the second network data includes network data of the first base station accessing the first network node, so as to facilitate the intelligent management and control center to determine the corresponding node selection strategy, and further ensure service continuity and user experience.

[0178] See Figure 3 , Figure 3 is a flowchart of a data processing method provided by an embodiment of the present application, which is applied to an intelligent management and control center. As Figure 3 shown, it includes the following steps:

[0179] Step 301, receive the first network data and the second network data sent by the first network data function;

[0180] Wherein, the first network data includes network data of the network function of the first network node corresponding to the first network data function, and the second network data includes network data of the first base station accessing the first network node.

[0181] Optionally, based on the above embodiment, the intelligent management and control center may further determine a node selection strategy, etc.

[0182] Optionally, when the terminal initially accesses the network, the intelligent management and control center may send a first node selection policy to the terminal; wherein, the first node selection policy includes information of a third base station and / or information of a third network node, the third base station includes a base station for providing services to the terminal, and the third network node includes a network node for providing services to the terminal.

[0183] For example, the intelligent management and control center may receive an access request from the terminal and send a first node selection policy to the terminal according to the access request.

[0184] Optionally, the intelligent management and control center may predict the network situation and / or optimize the access policy of the terminal according to one or more of the first network data and the second network data and the historical data reported by the terminal.

[0185] For example, the intelligent management and control center may use reliable analysis and prediction models to evaluate and analyze different types of users based on the collected network data and the self and service data reported by historical terminals, determine the movement trajectories and service usage habits of users, and predict user behaviors.

[0193] See Figure 4 , Figure 4 is a flowchart of the data processing method provided by the embodiment of the present application, applied to a terminal, such as Figure 4As shown in the figure, the method includes the following steps:

[0194] Step 401: During the process of initially accessing the network, receive the first node selection policy sent by the intelligent management and control center.

[0195] For example, the terminal may send an access request to the intelligent management and control center and receive the first node selection policy sent by the intelligent management and control center based on the access request.

[0196] Step 402: Access the network according to the first node selection policy.

[0197] The first node policy is determined by the intelligent management and control center according to the updated first network data and the updated second network data. The first network data includes the network data of the network functions of the first network nodes corresponding to the first network data function, and the second network data includes the network data of the first base station accessing the first network node.

[0201] The following describes the specific implementation process of the embodiment of the present application in detail in combination with different embodiments. In the following embodiments, taking the distributed node 1 as an example, the interaction process between the intelligent management and control center and each distributed node is represented, and the principle of the processing process of the intelligent management and control center and the centralized node is the same.

[0202] Such as Figure 5As shown, it is a flowchart of data processing of an embodiment of the present application, which may include:

[0203] Step 501: After registration, each NF, database, etc. of distributed node 1 actively sends a data reporting request to the NWDF of distributed node 1, and reports network data, including node data information and network status, etc.

[0204] Step 502: After receiving the data, the NWDF of distributed node 1 sends a data reporting response to each NF, database, etc. of distributed node 1.

[0205] Step 503: The NWDF of distributed node 1 initiates a data collection request to the RAN connected to distributed node 1 through the IP (or subsequent RAN service interface) of the RAN connected to distributed node 1 reported by the AMF of distributed node 1, and obtains network data of the RAN, such as data, status, resources, etc., and carries the update subscription identifier.

[0206] Step 504: RAN sends a data collection response to the NWDF of distributed node 1 and returns data.

[0207] Step 505: The NWDF of distributed node 1 sends a data reporting request to the intelligent management and control center, and reports the collected network data, such as node data information and network status.

[0208] Step 506: After receiving the data, the intelligent management and control center sends a data reporting response to the NWDF of distributed node 1.

[0209] Step 507: If the network data of the distributed node 1 is updated, the updated data is automatically reported to the NWDF.

[0210] Step 508: If the RAN data accessing the distributed node 1 is updated, the updated data is automatically reported to the NWDF.

[0211] Step 509: If the NWDF has data update, the updated data will be automatically reported to the intelligent management and control center.

[0212] like Figure 6 As shown, it is a flowchart of the initial selection of the terminal to access the RAN and network nodes in an embodiment of the present application, assuming that the intelligent control center has collected the network data of each network node in the network and the network data of the RAN accessing the network. It may include:

[0213] Step 601: The terminal sends a request to the intelligent management and control center to obtain a node selection policy, reports service type, slice information, UE (User Equipment) capabilities and other information, and obtains a node selection policy, including information about RAN and network nodes.

[0214] Step 602: The intelligent management and control center comprehensively analyzes the information reported by the terminal, as well as the resource data of the network nodes and the RAN, the service range of the serving terminal, the network status, and historical stability data, etc., formulates the node selection strategy for the RAN and network nodes of the terminal, and returns a policy response to the terminal.

[0215] Among them, the specific method for formulating the strategy by the intelligent management and control center is not limited in the embodiments of the present application.

[0216] Step 603: After receiving the selection strategy from the intelligent management and control center, the terminal initiates an access request to the corresponding RAN and network nodes.

[0217] Step 604: The distributed network node updates the data to the NWDF of this distributed node.

[0218] Step 605: The RAN updates the data to the NWDF of the accessed distributed node.

[0219] Step 606: The NWDF of the distributed node reports the data update to the intelligent management and control center.

[0220] Step 607: Perform subsequent other service request processes.

[0221] In addition, the intelligent management and control center can evaluate and analyze different types of users, determine the user's movement trajectory and service usage habits, and predict user behavior by using reliable analysis and prediction models based on the collected network data and the data of the terminal itself and services reported historically. The intelligent management and control center can realize the statistics and prediction of users and network performance based on the analysis and prediction data, so as to optimize the strategies of wireless resource management, slice resource and selection, service and access, etc. for the terminal in advance.

[0222] If during the process that the terminal has normally accessed the RAN and network nodes and is providing normal services, the RAN or network node suddenly crashes or exits the network and other operations that cannot continue to serve the terminal, the network will immediately report to the intelligent management and control center, and the intelligent management and control center will re-select the RAN or the accessed network node for the terminal to ensure the service continuity of the terminal and the user experience.

[0223] As Figure 7 shown, it is the processing flow chart for the situation where the RAN itself cannot provide services during the terminal service process in the embodiments of the present application. In Figure 7 the shown embodiment, when the RAN itself cannot provide services during the terminal service process, other RANs within the node are preferentially selected. That is, when the terminal is normally accessing and providing services, if the RAN suddenly crashes or other situations where it cannot continue to serve the terminal occur, the intelligent management and control center will first consider selecting the RAN that the terminal can access within this network node to take over the terminal's services. It may include:

[0224] Step 700: When the terminal is accessing the service normally, the RAN suddenly fails to provide service.

[0225] Step 701: The non-functional RAN ( Figure 7 the old-RAN in it) updates the data to the NWDF of the corresponding distributed node, indicating that it cannot provide normal service. If this function is also lost, this step is skipped.

[0226] Step 702: The distributed node updates the data to the corresponding NWDF, including carrying the identifier of the non-functional RAN.

[0227] Step 703: The NWDF of the distributed node updates the data to the intelligent management and control center.

[0228] Step 704: The intelligent management and control center updates the RAN selection strategy according to the updated network data and the previously saved terminal information. The intelligent management and control center can give priority to considering the RAN within the coverage of the currently serving network node to take over the service of the terminal, and return the selection strategy to the terminal.

[0229] Step 705: The terminal returns a policy response to the intelligent management and control center.

[0230] Step 706a: The terminal sends an access request to the new RAN ( Figure 7 the New-RAN in it).

[0231] Step 706b: The new RAN sends an access request to the distributed node.

[0232] Step 707a: The new RAN updates the data to the NWDF of the corresponding distributed node.

[0233] Step 707b: The distributed node updates the corresponding NWDF.

[0234] Step 708: The NWDF of the distributed node updates the data to the intelligent management and control center.

[0235] Step 709: Proceed with the subsequent other service request processes.

[0236] As Figure 8 shown, it is the processing flow chart for the situation where the RAN itself fails to provide service during the terminal service process of this application embodiment. In this embodiment, when the RAN itself fails to provide service during the terminal service process, the RAN and the network node are comprehensively selected. That is, if there is no eligible RAN within the current network node, the intelligent management and control center can optimize the strategy according to the terminal request and network conditions, etc., and re-select the access RAN and network node. It may include:

[0237] Step 800: When the terminal is accessing the service normally, the RAN suddenly fails to provide service.

[0238] Step 801: The non-functional RAN ( Figure 8 the old-RAN in it) updates the data to the NWDF of the corresponding distributed node, indicating that it cannot provide normal service. If this function is also lost, this step is skipped.

[0239] Step 802: The distributed node updates the data to the corresponding NWDF, including carrying the identifier of the non-functional RAN.

[0240] Step 803: The NWDF of the distributed node updates the data to the intelligent management and control center.

[0241] Step 804: The intelligent management and control center cannot select a RAN within the current access network node to take over the terminal service through data analysis. Therefore, a new access RAN and network node are selected for the terminal, and the selection strategy is returned to the terminal.

[0242] Step 805: The terminal returns a policy response to the intelligent management and control center.

[0243] Step 806: The terminal sends an access request to the newly selected RAN ( Figure 8 the New-RAN in it) and network node ( Figure 8 the New-distributed node in it).

[0244] Step 807: Subsequent data update and service process.

[0245] As Figure 9 shown, it is a flowchart for handling the situation where the network node itself fails to provide service during the terminal service process of this application embodiment. In the embodiment of this application, during the terminal service process, if the network node itself fails to provide service, the intelligent management and control center can preferentially select other network nodes that the RAN can access. That is, when the terminal is accessing and serving normally, if the network node suddenly crashes or other situations where it cannot continue to serve the terminal occur, the intelligent management and control center should first consider selecting network nodes that the currently accessed RAN can access to take over the terminal's service.

[0246] Step 900: When the terminal is accessing the service normally, the network node suddenly fails to provide service.

[0247] Step 901: The RAN updates the data.

[0248] Step 902: The non-functional network node ( Figure 9 the old-distributed node in it) updates the data to the NWDF of the corresponding distributed node, indicating that it cannot provide normal service.

[0249] Step 903: The NWDF of the distributed node updates data to the intelligent management and control center.

[0250] Step 904: The intelligent management and control center cannot select a RAN within the currently accessed network node to take over the terminal service through data analysis. Therefore, it selects a network node that the currently accessed RAN can access for the terminal and returns a selection policy to the terminal.

[0251] Step 905: The terminal returns a policy response to the intelligent management and control center.

[0252] Step 906: The terminal sends an access request to the newly selected network node ( Figure 9 New - distributed node in).

[0253] Step 907: The newly selected network node updates data to the NWDF of the corresponding distributed node.

[0254] Step 908: The NWDF of the distributed node updates data to the intelligent management and control center.

[0255] Step 909: Subsequent data update and service process.

[0256] As Figure 10 shown, it is a processing flow chart for the situation where the network node itself cannot provide services during the terminal service process of this application embodiment. When the network node itself cannot provide services during the terminal service process, the RAN and the network node are comprehensively selected. That is, if there is no eligible network node accessed by the currently accessed RAN, the intelligent management and control center can optimize the policy according to the terminal request and network conditions, etc. as shown in Figure 5 the embodiment shown, and re - select the accessed RAN and network node.

[0257] Step 1000: When the terminal is performing normal access service, the network node suddenly fails to provide services.

[0258] Step 1001: The original RAN ( Figure 10 old - RAN in) updates data to the NWDF of the corresponding distributed node.

[0259] Step 1002: The original distributed node ( Figure 10 old - distributed node in) updates data to the corresponding NWDF, indicating that it cannot provide normal services.

[0260] Step 1003: The NWDF of the distributed node updates data to the intelligent management and control center.

[0261] Step 1004: The intelligent management and control center cannot select a RAN within the currently accessed network node to take over the terminal service through data analysis. Therefore, a new access RAN and network node are selected for the terminal, and a selection policy is returned to the terminal.

[0262] Step 1005: The terminal returns a policy response to the intelligent management and control center.

[0263] Step 1006: The terminal sends an access request to the newly selected RAN (New-RAN in Figure 10 ) and network node (New-Distributed Node in Figure 10 ).

[0264] Step 1007: Subsequent data update and service process.

[0265] In the embodiment of the present application, during the process of terminal service, the intelligent management and control center can also update the RAN and network node selection policies.

[0266] When the terminal is normally accessed and in service, the intelligent management and control center updates the RAN and network node selection policies for the terminal according to the terminal location, service resources of the RAN, service resources and stability of the network node, etc. (the gain after the terminal reconnects is greater than the energy consumption of reconnection, etc.).

[0267] As Figure 11 shown, during the terminal service process, the intelligent management and control center can update the RAN selection policy within the same node. When the terminal is normally accessed and in service, if the intelligent management and control center reselects a better accessible RAN within this network node for the terminal according to the terminal location, service resources of the RAN, etc., it will return the updated policy result to the terminal, and the terminal will select whether to access the new RAN according to its own configuration. If it chooses not to access the new RAN, the terminal will ignore the policy. If the terminal receives the new policy, it specifically includes:

[0268] Step 1100: When the terminal is normally accessing and serving, the intelligent management and control center reselects other accessible RANs within this node for the terminal according to the network situation.

[0269] Step 1101: The intelligent management and control center returns the updated RAN selection policy to the terminal.

[0270] Step 1102: The terminal returns a policy response to the intelligent management and control center.

[0271] Steps 1103 - 1105: Handover process.

[0272] Step 1106a: The new RAN (New-RAN in Figure 11 ) updates data to the NWDF of the distributed node.

[0273] Step 1106b: The original RAN ( Figure 11 Old-RAN in it) updates data to the NWDF of the distributed node.

[0274] Step 1107: The NWDF of the distributed node reports the updated data to the intelligent management and control center.

[0275] Step 1108: Execute other service request processes.

[0276] As Figure 12 shown, during the process of terminal service, the intelligent management and control center updates the selection strategies of the RAN and network nodes. When the terminal is normally accessed and serviced, if the intelligent management and control center reselects a better RAN and network nodes for the terminal according to the terminal location, service resources of the RAN, resource status of the network nodes, etc., it will return the updated policy result to the terminal, and the terminal will select whether to access the new RAN and network nodes according to its own configuration. If it chooses not to access, the terminal will ignore the policy. If the terminal receives the new policy, it may include:

[0277] Step 1200: When the terminal is normally accessing the service, the intelligent management and control center reselects new RAN and network nodes for the terminal according to the network situation.

[0278] Step 1201: The intelligent management and control center returns the updated selection strategies of the RAN and network nodes to the terminal.

[0279] Step 1202: The terminal returns a policy response to the intelligent management and control center.

[0280] Steps 1203 - 1205: Handover process.

[0281] Step 1206a: The new distributed node ( Figure 12 New distributed node in it) updates data to the NWDF of the New distributed node.

[0282] Step 1206b: The new RAN ( Figure 12 New-RAN in it) updates data to the NWDF of the New distributed node.

[0283] Step 1207: The NWDF of the New distributed node reports the updated data to the intelligent management and control center.

[0284] Step 1208a: The original distributed node ( Figure 12 Old distributed node in it) updates data to the NWDF of the Old distributed node.

[0285] Step 1208b: The original RAN ( Figure 12The Old-RAN) updates data to the NWDF of the Old distributed node.

[0286] Step 1209: The NWDF of the Old distributed node reports the updated data to the intelligent management and control center.

[0287] Step 1210: Execute other service request processes.

[0288] It can be seen from the above description that by introducing the network data function NWDF and the intelligent management and control center into the network, the global data of the distributed network can be monitored and analyzed, so as to optimize the network status and terminal access situation, select the most suitable access RAN and network nodes for the terminal to serve, and improve service continuity and user experience.
