It should be noted that, in the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.
The communication nouns to which the present application relates are first described below.
(1) 5G network data analysis service
Referring to fig. 2 and 3, the network data analysis function (Network Data Analytics Function, NWDAF) is one of the 5G core network control plane (5 GC) network functions, and interacts with different entities according to different purposes:
collecting data based on event subscriptions provided by access and mobility management functions (Access and Mobility Management Function, AMF), session management functions (Session Management Function, SMF), policy control function entities (Policy Control Function, PCF), unified data management entities (Unified Data Management, UDM), application functions (Application Function, AF) (either directly or through network opening functions (Network Exposure Function, NEF)) or operation management maintenance (Operation Administration Maintenance, OAM);
using a data collection coordination function (Data Collection Coordination Function, DCCF) for analysis and data collection;
retrieving information from a data store (e.g., retrieving user-desired requests (User Desired Requirement, UDR) for user-related information via a UDM);
storing and retrieving information from an analytical data store function (Analytics Data Repository Function, ADRF);
Analyzing and data collecting from the messaging framework adapter function (Messaging Framework Adaptor Function, MFAF);
retrieving information about Network Function entities (Network functions, NFs) (e.g., retrieving information related to NFs from NF storage functions (NF Repository Function, NRF);
providing an analysis to the consumer according to the demand;
providing a consumer with a large amount of data.
Although the 5G core network control plane NWDAF supports data analysis based on core network Control Plane (CP) data and optionally analysis and data collection by DCCF, its functionality is limited to subscription events provided by the 5G core network control plane network functions and does not support data collection for the core network user plane, radio access network and UE. In addition, the existing network does not support real-time data subscription and service, on one hand, interface performance and function design are not supported, and on the other hand, network element equipment does not consider the cost due to the function related to the non-standardized data service, so that a large amount of real-time data reporting can influence network performance.
(2) 5G O-RAN network architecture
As shown in fig. 4, the open radio access network (Open Radio Access Network, O-RAN) proposes wireless intelligent controllers (RAN intelligence controller, RIC), including Non-Real time wireless intelligent controllers and near Real time wireless intelligent controllers, as compared to existing 5G radio access network architecture and functionality. From the management plane, a non-real-time wireless intelligent controller is added in the service management and arrangement system, and strategy, auxiliary information and the like are sent in an interactive way with the near-real-time wireless intelligent controller through an A1 interface. From the network function, a near real-time wireless intelligent controller is introduced, and is connected with a base station (such as gNB or eNB, etc.) or a base station subsystem (part of baseband functions such as CU-CP (centralized unit-control plane), CU-UP (centralized unit-user plane) or DU (distributed unit)) through an E2 interface, so that data can be acquired, strategy and control information can be sent, etc.
The wireless intelligent controller of the O-RAN is an intelligent function hung by the 3GPP 5G protocol standard, and although the near real-time wireless intelligent controller is defined as a network function in the O-RAN standard, the near real-time wireless intelligent controller can be connected with a plurality of gNB/gNB-CU/gNB-CU-CP/eNB, is transparent to CN and UE, and therefore the logic connection relationship is more similar to the network management function. Moreover, the near-real-time wireless intelligent controller is focused on data analysis application at the network side, and cannot support providing data collection and analysis services for external functions of the network. Because the category belongs to the wireless side, the UE ID association problem of persistent data cannot be supported for UE-level data. In addition, the resources of the wireless side network device are more scarce, so that the existing base station device cannot support reporting of a large amount of near-real-time or real-time data when the traffic load is high.
(3) 5G UE capability definition and reporting scheme
According to the definition of 38.822UE features, a part of mandatory features (mandatory feature) are UE capability (capability) signaling interactions are not required. If the Network needs to know other UE capability information on the basis of the mandatory feature, according to the definition of 38.331, as shown in fig. 5, the Network (Network) may send a UE capability request (UE capability requirement) to the UE, and the UE reports the corresponding UE capability information (UE capability information) based on the request message. UE capabilities are defined at 38.306, with the UE capabilities currently being based on radio access individual protocol layers (traffic data adaptation protocol (Service Data Adaption Protocol, SDAP)/packet data convergence protocol (Packet Data Convergence Protocol, PDCP)/radio link control (Radio Link Control, RLC)/medium access control (Media Access Control, MAC)/physical layer (PHY)).
The definition of the existing protocol UE feature and UE capability and the UE capability reporting scheme do not consider the content related to the target surface, and the content needs to be considered after the target surface is introduced.
The method and the device for reporting and acquiring the target surface capability of the network function instance or the network element provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 6, an embodiment of the present application provides a method for reporting target plane capability of a network function instance or a network element, including:
step 61: the first network function instance or the network element reports the target surface capability information of the first network function instance or the network element, wherein the target surface is a protocol function surface for supporting at least one of data collection, data distribution, data security, data privacy, data analysis and data preprocessing.
The network function instance refers to a 3GPP or 3GPP defined processing module employed in the network, having defined functional behaviors and 3GPP defined interfaces, and the network function may be implemented as a network element on dedicated hardware, a software instance running on dedicated hardware, or a virtualized function instantiated on a suitable platform (such as a cloud infrastructure). The network function instance is implemented by software and/or hardware capable of running the network function.
A network element refers to a discrete telecommunication entity in the network that can be managed through a specific interface.
In the embodiment of the application, the capability of the target surface comprises the capability of the network function instance or the network element for carrying out the interaction of the control information and/or the data information of the target surface. The control information of the target surface comprises configuration information of one or more of the functions of connection establishment, data collection, data distribution, data security, data privacy, data analysis, data preprocessing and the like of the target surface, and the data information of the target surface comprises data required by the execution of the functions.
In the application, a target plane is used as a protocol function plane which is newly added on the basis of a Control Plane (CP) and a User Plane (UP) and is used for supporting at least one of data collection, data distribution, data security, data privacy, data analysis and data preprocessing. The target plane may also be referred to as a data plane.
In the embodiment of the application, the target surface can be used for network optimization, so that the network efficiency and the user experience are improved; the method can also be used for realizing 6G newly added application services (such as perception, calculation and the like) with high service quality (Quality of Service, qoS) guarantee; and a data anchor point can be provided for the user, so that the data rendering and data security requirements of the user are met. For each network function instance or network element, the target surface characteristics and the capability definition can meet the requirements of operators on the data surface according to the software and hardware design functions and the willingness of operators, and the software and hardware design cost of equipment operators can be reduced, so that various situations and different combinations of situations of the software and hardware design are supported.
In the embodiment of the application, the network function instance or the network element reports the capability information of the target surface, and the target surface is a protocol function surface for supporting at least one of data collection, data distribution, data security, data privacy, data analysis and data preprocessing, so that the data collection and the use of the end-to-end network function are realized.
In an embodiment of the present application, optionally, the target surface capability information includes at least one of the following:
1) Information indicating whether the first network function instance or network element supports a target plane;
2) Information indicating that the first network function instance or network element supports providing data to a network internal function and/or providing data to a network external function;
wherein the data comprises: the first network function instance or the network element itself may generate data and/or receive data of other functions; the network internal functions and/or the network external may be further refined based on security levels or security domains. For example supporting network functions with security level a outside the network.
3) Information indicating whether the target surface capability is a static capability or a dynamic capability;
in the embodiment of the present application, the static capability indicates that the target plane capability is static and is not dynamically adjusted, for example, the static capability may be a maximum target plane capability or a minimum target plane capability that can be supported by the first network function instance or the network element, where the capability may be set by the first network function instance or the network element according to its own hardware design and/or resource allocation, and a definition of the minimum capability refers to a target plane capability that is supported when meeting a peak performance (peak throughput and/or peak user number, etc.) condition or a high load of a communication service, etc.; the definition of maximum capability refers to the target surface capability that can be supported when the target surface is prioritized or under low load.
Dynamic capabilities means that the capabilities of the target plane are dynamic and can be dynamically adjusted, e.g. dynamic capabilities dynamically adjust updates with the weight of the first network function instance or network element communication load. One way to define dynamic capabilities is to select one or more key target-plane capability parameters (such as storage size, rate, subscription data item) as capability information of interest of the target plane according to the requirement of the target plane, and consider that the target-plane capability is dynamically changed if the change occurs or meets a certain condition. Another way of defining the dynamic capabilities is to define one or more combinations of communication capabilities and/or target plane capabilities based on the communication load (parameters related to the user plane and/or the control plane) and/or the target plane load, which may be further classified into one or more classes based on the situation of the target plane capabilities.
When the target surface capability is static capability, the first network function instance or the network element reports or queries corresponding target surface capability information by the network, and the corresponding target surface capability information is unchanged. When the target surface capability includes static capability and dynamic capability, the maximum or minimum target surface capability is generally taken as an upper limit or a lower limit of the target surface capability, and the current capability condition is dynamically decided according to influence factors.
In the foregoing embodiment, the target plane capability defining manner associated with the relevant parameters of the user plane and/or the control plane (such as the number of active users, the uplink throughput, the downlink throughput, the uplink utilization (such as the PUSCH RB utilization), the downlink utilization (such as the PDSCH/PDCCH RB utilization), the RRC connection number, the PDU session average flow or the radio bearer (such as the DRB) average flow, the perceived service/task number, and the calculated service/task number) may be potentially advantageous in that the relevant parameters of the user plane and/or the control plane of the first network function instance or the network element in the existing communication flow may be collected by the communication measurement volume or the network management, so that the target plane may query the relevant parameters of the user plane and/or the control plane to the corresponding network function and/or the network management function, and the target plane capability of the first network function instance or the network element may be known based on the relevant parameters of the user plane and/or the control plane.
In the embodiment of the present application, if the definition of the dynamic capability of the target plane of the first network function instance or the network element is defined by the combination of the values or the value intervals of the key parameters of the user plane and/or the control plane and the dynamic capability of the target plane, the first network function instance or the network element target plane dynamic capability information, and the network function of the target plane (such as the first target plane network function instance or the second target plane network function instance) may query the network management function or other network functions for the key parameter values of the user plane and/or the control plane defined in combination with the target plane dynamic capability, and further obtain the target plane capability information based on the combination definition information. The joint definition may be that different values or value intervals of key parameters of the user plane and/or the control plane are defined as different communication capability levels, and then the capability level of the target plane and the communication capability level have a mapping relation. For example, the first network function instance or the network element communication capability state is defined as three levels of high, medium and bottom based on the information such as the uplink and downlink PRB utilization, the number of RRC connection state users, and the uplink and downlink speeds, and corresponds to the first network function instance or the network element three target plane capabilities, and examples are shown in the following table. The target surface network function instance inquires parameter values or grade information of the current communication capability state of the first network function instance or the network element, and then the current capability grade of the terminal target surface is obtained.
| Communication capability level | Target surface capability level |
| High height | Low and low |
| In (a) | In (a) |
| Low and low | High height |

6) A supported target surface data reporting mode;

in the embodiment of the present application, optionally, the transmission direction of the supported target plane includes uplink and/or downlink. The control information interaction capability of the target plane is usually both upstream and downstream. For the data interaction capability of the target surface, if uplink is supported, the first network function instance or the network element supports the data reporting of the target surface; if downstream is supported, it means that the first network function instance or network element supports reception of target plane data.
For example, reporting communication data may be communication measurement data required for providing communication service quality optimization, reporting perception data may be providing perception measurement quantity required for perception, reporting calculation or AI data may be providing calculation input and/or output data required for calculation, receiving communication data may be data information required for local communication decision of the first network function instance or the network element, receiving perception data may be receiving perception measurement quantity or perception result required for local perception or decision, and receiving calculation input and/or output data.
11 The maximum data uplink rate of the supported target surface;
the maximum data uplink rate of the supported target surface can also be expressed as the supported maximum data collection rate or the maximum reporting rate. To avoid that the continuous data range of the item is too large, representing difficulties, different rate ranges may be defined as different levels of rate, and then the item only needs to give level information, improving the representation efficiency.
12 A supported target plane maximum data downlink rate;
the term may also be expressed as a supported maximum data usage rate or maximum data distribution rate or maximum reception rate. Likewise, different rate ranges may be defined as different levels of rate, so this term only needs to give level information to improve the presentation efficiency.
13 The total buffer size of the target surface;
the term may be the total buffer size of all protocol layers, or may be a hierarchical total buffer size, such as a Layer-2 (Layer 2) total buffer size and/or a Layer-3 (Layer 3) total buffer size.

this is used to indicate the maximum data collection items that can be supported simultaneously, e.g., maximum simultaneous support of reference signal received power (Reference Signal Received Power, RSRP) and reference signal received quality (Reference Signal Received Quality, RSRQ) 2 items of data collection, because data collection requires corresponding hardware resources and software processing support. This term may be the maximum number of data collection terms that can be supported for all data. When classifying or hierarchically defining data, this term may also be expressed as the maximum number of data collection terms supported for a certain class or level of data.
16 The size of the ID sequence number supported;
For example, in the data collection configuration, a data collection subscription ID is typically sent to the first network function instance or network element, and the length of the ID number may be represented by how many bits; when the first network function instance or network element needs to use the data provided by the target plane, there is also a corresponding data receiving subscription ID.
17 A minimum temporal granularity of supported data collection;
a minimum time granularity of data that the first network function instance or network element is able to collect is indicated, e.g. for RSRP, the minimum time granularity is per Transmission Time Interval (TTI).
18 A minimum time granularity of supported data reporting;

In the first embodiment of the application: target surface capability reporting scheme based on interface between network function examples

In the second embodiment of the application: network function instance or network element target surface capability reporting+on-demand query scheme based on service architecture
The service-oriented core network functions, or the 6G radio access network, may also evolve towards the service direction. In the service architecture, in order to facilitate discovery of network function instances or network elements and maintenance of description information (profile) of the network function instances or network elements, a certain network function instance is typically set to be responsible for the above functions. In the following embodiments, this network function instance is referred to as a network storage function (Network Repository Function, NRF), and accordingly, a network function instance or a network element target plane capability reporting scheme is briefly described as follows:
Step 1: the first network function instance or network element sends the description information of the first network function instance or network element to the NRF (i.e. the second network function instance), wherein the description information comprises the first network function instance or network element target plane capability information.
Step 2: the first target plane network function instance is a first network function instance or network element selected according to an external data request and/or an internal function decision.

Step 4: the NRF sends the target plane capability information of the first network function instance or the network element to the first target plane network function instance.
The third embodiment of the application: reporting scheme for static capacity and dynamic capacity
As described in the foregoing technical solutions, the embodiments of the present application consider a reporting scheme of static capability and dynamic capability when the first network function instance or the network element supports static capability and/or dynamic capability. For example, static capability may be defined as maximum capability and/or minimum capability, where a definition of minimum capability refers to a target surface capability condition supported when peak performance (peak throughput and/or peak number of users, etc.) conditions or high load of communication services are met; the definition of maximum capability refers to the target surface capability that can be supported when the target surface is prioritized or under low load. One way to define dynamic capabilities is to select one or more key target-plane capability parameters (such as storage size, rate, subscription data item) as capability information of interest of the target plane according to the requirement of the target plane, and consider that the target-plane capability is dynamically changed if the change occurs or meets a certain condition. Another way of defining the dynamic capabilities is to define one or more combinations of communication capabilities and/or target plane capabilities based on the communication load (parameters related to the user plane and/or the control plane) and/or the target plane load, which may be further classified into one or more classes based on the situation of the target plane capabilities.
In the foregoing embodiment, the target plane capability defining manner associated with the relevant parameters of the user plane and/or the control plane (such as the number of active users, the uplink throughput, the downlink throughput, the uplink utilization (such as the PUSCH RB utilization), the downlink utilization (such as the PDSCH/PDCCH RB utilization), the RRC connection number, the PDU session average flow or the radio bearer (such as the DRB) average flow, the perceived service/task number, and the calculated service/task number) may be potentially advantageous in that the relevant parameters of the user plane and/or the control plane of the first network function instance or the network element in the existing communication flow may be collected by the communication measurement volume or the network management, so that the target plane may query the relevant parameters of the user plane and/or the control plane to the corresponding network function and/or the network management function, and the target plane capability of the first network function instance or the network element may be known based on the relevant parameters of the user plane and/or the control plane.
In the embodiment of the present application, if the definition of the dynamic capability of the target plane of the first network function instance or the network element is defined by the combination of the values or the value intervals of the key parameters of the user plane and/or the control plane and the dynamic capability of the target plane, the first network function instance or the network element target plane dynamic capability information, and the network function of the target plane (such as the first target plane network function instance or the second target plane network function instance) may query the network management function or other network functions for the key parameter values of the user plane and/or the control plane defined in combination with the target plane dynamic capability, and further obtain the target plane capability information based on the combination definition information. The joint definition may be that different values or value intervals of key parameters of the user plane and/or the control plane are defined as different communication capability levels, and then the capability level of the target plane and the communication capability level have a mapping relation. For example, the first network function instance or the network element communication capability state is defined as three levels of high, medium and bottom based on the information such as the uplink and downlink PRB utilization, the number of RRC connection state users, and the uplink and downlink speeds, and corresponds to the first network function instance or the network element three target plane capabilities, and examples are shown in the following table. The target surface network function instance inquires parameter values or grade information of the current communication capability state of the first network function instance or the network element, and then the current capability grade of the terminal target surface is obtained.
| Communication capability level | Target surface energyForce rating |
| High height | Low and low |
| In (a) | In (a) |
| Low and low | High height |
In the embodiment of the application, the target surface capability updating condition can be one or more of the following:
1) The grade of the target surface capacity of the first network function instance or the network element changes;
in the embodiment of the application, the target surface capacity can be defined into a plurality of grades according to the parameters, the numerical range and the like of the target surface capacity, and when the capacity is changed from one grade to another grade, the capacity needs to be updated;
2) And the parameters and/or the numerical range of the target surface capability of the first network function instance or the network element configured by the target surface network function instance meet the preset condition.
For example, the target plane network function instance configures the update capability when the target plane total buffer size (total buffer size) is less than a.
If the first network function instance or the network element target surface capability changes, the update mode may adopt the following potential update method:
1) A first network function instance or network element updates description information of the first network function instance or network element to an NRF, wherein the description information comprises target surface capability information of the first network function instance or network element; the NRF is used for maintaining the target surface capability information of the network function instance or the network element; the target network function instance subscribes the target network function instance or network element capability information of one or more network function instances or network elements to the NRF, and when the NRF receives the capability update information, the NRF sends the capability update information to the target network function instance.
2) When the change of the target surface capability affects the function flow related to the target surface in which the first network function instance or the network element participates, the first network function instance or the network element reports the target surface capability information of the first network function instance or the network element to the target surface network function instance without being transferred by an NRF or other network functions, and the mode is beneficial to the target surface to make adjustment according to the update condition more quickly;
3) If the target plane function requests the target plane capability information of the first network function instance or network element or NRF or other network function (such as AMF), the corresponding function sends the corresponding target plane capability information.
Referring to fig. 10, when the first network function instance or the network element supports both dynamic capability and static capability, and supports multiple update manners, and the update manners are configurable, the relevant steps of a target plane capability reporting scheme are briefly described as follows:
step 1: reporting static capability to NRF when the first network function instance or network element establishes interface connection, wherein the static capability can be maximum capability and/or minimum capability, and the target network function instance can be the first target network function instance and/or the second target network function instance and/or the third target network function instance. The first target surface network function instance is a core network target surface network function instance; the second target plane network function instance is a radio access network target plane network function instance, and the third target plane network function instance is a UE target plane network function instance.
Step 2: the target plane network function instance decides the reporting/updating mode of the first network function instance or the network element target plane capability according to the static capability and/or other information.
Step 3: the target plane network function instance transmits a mode configuration and/or condition, wherein the mode configuration may be configured to change one or more of active reporting, configuration condition reporting, and query reporting, provided that the condition of the target plane capability change, e.g., a level-based capability change, a critical capability parameter, and/or a threshold, etc.
Step 4: the first network function instance or the network element and the target plane function report/update the dynamic capacity according to the information and/or other information in the step 3.
In the embodiment of the application, the first network function instance or the network element can support the target surface function according to the requirement of the target operator and/or the hardware cost and the like when designing. And when the network function supports the target surface, the network function can share hardware resources with other processes such as communication in a dynamic capability mode, and when the dynamic capability related to the related parameters of the user surface and/or the control surface is used, the mapping of the related parameters of the user surface and/or the control surface can be based, so that the cost for updating the dynamic capability is saved.
The execution subject can be the target surface capability reporting device of the network function instance or the network element. In the embodiment of the application, the method for reporting the target surface capability of the network function instance or the network element by using the target surface capability reporting device of the network function instance or the network element as an example is explained.
