Description

Technical Field

[0001] The present invention relates to the field of 5G communication technology, and in particular to a method, device, equipment and storage medium for collecting terminal information in a 5G network. Background Art

[0002] 5G (5th Generation Mobile Communication Technology) networks are designed for a more extreme service experience, providing ultra-high bandwidth, ultra-low latency, and ultra-high-density connectivity. This places increasingly complex demands on network resource management and scheduling, and traditional data analysis architectures are struggling to meet these demands. To meet the demand for faster and more real-time network automation management and optimization, 3GPP (3rd Generation Partnership Project) has designed a core network data analysis architecture based on the Network Data Analytics Function (NWDAF) in 5G networks to collect and analyze network data. The architecture also defines a series of functions and processes for data collection, storage, analysis, and management.

[0003] However, the current NWDAF can only collect data from 5G core network elements. A channel between the NWDAF and the UE (User Equipment, also known as the 5G terminal) has not yet been established. Therefore, the NWDAF cannot directly collect relevant information from the UE. For example, the uplink packet loss rate (UL PLR) calculated by the UE through PMF (Performance Measurement Function) messages exchanged between the UE and the UPF (User Plane Function) can differ from the downlink packet loss rate calculated by the network-side UPF even in TDD (Time Division Duplex) mode. In FDD (Frequency Division Duplex) mode, the difference is even more significant due to the lack of TDD channel reciprocity. Therefore, collecting UE-side parameters is important for improving the network's perception of UE-side performance and optimizing parameters. In addition, with the gradual deepening of research on integrated communication and perception in the 5G-Advanced stage, the integration of the logical network element SF (Sensing Function) responsible for perception processing and the NWDAF in the network architecture is also one of the current mainstream options. The NWDAF also has the need to obtain CSI (Channel State Information), location and other perception information from the UE.

[0004] It can be seen that collecting terminal-side information (i.e., UE-side information) in 5G networks has become an important issue that the industry urgently needs to solve. Summary of the Invention

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation, and are therefore not to be construed as limiting the present invention. Unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be broadly construed, for example, to mean a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following combination Figures 1-4 Specific embodiments of the present invention are described.

[0037] In one embodiment, Figure 1 As shown, a method for collecting terminal information in a 5G network is provided, and the method is applied to Figure 1 The following steps are used to illustrate the use of the NWDAF (Network Data Analytics Function) network element in the example:

[0038] Step 101: Invoke the N1N2 message transmission service operation of the AMF network element; the N1N2 message transmission service operation carries a target terminal identifier and an N1 parameter management message container; the N1 parameter management message carried in the N1 parameter management message container is a UE parameter request message or a UE parameter subscription message; the N1N2 message transmission service operation is used to request the target terminal indicated by the target terminal identifier to report the parameter value corresponding to the parameter list to be reported included in the N1 parameter management message;

[0039] The Access and Mobility Management Function (AMF) network element is a key unit in the 5G core network. It directly manages UE access requests and performs registration, connection, reachability, and mobility management for UEs. The N1N2 message transfer service operation, Namf_Communication_N1N2MessageTransfer, is used by NF (Network Function) entities to send downlink N1 messages to UEs or N2 messages to NG(RAN) (Next Generation Radio Access Network, generally used to represent 5G access networks) through the AMF.

[0040] Specifically, if Figure 2 As shown, Figure 2 The timing diagram for collecting relevant measurement quantities on the UE side is shown. NWDAF calls the N1N2 message transmission service operation of AMF (i.e., Namf_Communication_N1N2MessageTransfer) to request the UE to report relevant parameters. The above-mentioned N1N2 message transmission service operation carries the target terminal identifier and the N1 parameter management (PM, Parametermanagement) message container (hereinafter referred to as the N1 PM message container). The N1 PM message carried in the N1 PM message container can be a UE parameter request message or a UE parameter subscription message; the N1 PM message also contains a parameter list of parameters to be reported that the NWDAF expects the UE to report. The parameters to be reported can be PLR, RTT, CSI, location information, CDRX parameters, and battery power information, etc. The format of the information element (IE) of the parameter list to be reported is shown in Table 1 below, where the D bit indicates the direction, a value of 1 indicates the downlink direction from the network to the UE, and a value of 0 indicates the uplink direction from the UE to the network:

[0041]

[0042]

[0043] Table 1 Parameter Lists Message

[0044] If there is no active N1 and N2 connection (i.e. the UE is in CM-IDLE state), the AMF needs to invoke the network-triggered service request procedure to page the UE and restore the N1 and N2 connections, such as Figure 2As shown in steps 2a-4a in , specifically including:

[0045] Step 2a: The AMF sends a Paging message to the NG(RAN) node included in the UE tracking area list;

[0046] Step 3a: The relevant NG (RAN) node sends a Paging message to page the UE.

[0047] Step 4a: The UE responding to the paging initiates a Service Request procedure to restore the air interface RRC connection and N2 connection;

[0048] If the UE is in the RRC-Inactive state, the NG (RAN) node initiates paging, and the UE responds to the paging and restores the RRC connection through the Resume process.

[0049] If N1 and N2 connections are available, the AMF sends the message to the UE or NG-RAN as requested, such as Figure 2 As shown in steps 5-6 in the , specifically including:

[0050] Step 5: The AMF sends a Downlink NAS Transport message to the NG (RAN), carrying a PM NAS (Non-Access-Stratum) message (a PM NAS message is a non-access stratum message carrying a parameter list, which can be divided into a request UE parameter message or a subscription UE parameter message);

[0051] Step 6: NG (RAN) sends a DL information transfer message to the UE, carrying a PM NAS message (request UE parameter message or subscription UE parameter message).

[0052] Step 102, subscribe to the UE parameter reporting event to the AMF network element, and receive an event open notification of the UE parameter reporting event from the AMF network element; wherein the parameter value is sent to the AMF network element by the target terminal through the response message of the N1 parameter management message of the N1 interface.

[0053] Specifically, NWDAF subscribes to the UE parameter reporting event from the AMF network element, and receives the event open notification (ie, Namf_EventExposure_Notify) of the UE parameter reporting event from the AMF network element; Figure 2 As shown in steps 7-9:

[0054] Steps 7-8: The UE reports the requested parameters to the AMF via the NG(RAN) according to the requirements of the PM NAS message. If the PM NAS message is a request for UE parameters, the UE parameter response NAS message is used to report; if the PM NAS message is a subscription UE parameter message, the UE parameter notification NAS message is used;

[0055] Step 9: AMF sends Namf_EventExposure_Notify to NWDAF, with Event ID "UE parameter reporting" and carrying the UE identifier and the parameters reported by the UE.

[0056] In the above embodiment, NWDAF subscribes to the UE parameter reporting event from the AMF network element and calls the N1N2 message transmission service operation of the AMF network element to request the UE to report relevant parameters. The AMF provides an open service for UE parameter reporting events, and the NWDAF obtains the parameters reported by the UE through the N1 PM response message by subscribing to this event. The present invention introduces the N1 PM (Parameter Management) message for parameter management and enhances the interface based on the existing process to open the parameter transmission channel between the UE and NWDAF, improve the network's perception of UE-side performance, and perform parameter optimization.

[0057] In one embodiment, if the N1 parameter management message in the N1 parameter management message container is a UE parameter request message, the UE parameter request message further includes a terminal parameter reporting mode, and the terminal parameter reporting mode is a periodic reporting mode or an immediate reporting mode;

[0058] If the N1 parameter management message in the N1 parameter management message container is a subscription UE parameter message, the subscription UE parameter message also includes the threshold of each parameter to be reported, and the parameter value is reported by the target terminal when the parameter to be reported exceeds the corresponding threshold.

[0059] Specifically, when the N1 parameter management message in the N1 parameter management message container is a UE parameter request message, the UE parameter request message also includes a terminal parameter reporting mode, and the terminal parameter reporting mode is a periodic reporting mode or an immediate reporting mode; when the NWDAF requests parameters from the UE, the parameter list format is as shown in Table 2:

[0060]

[0061] Table 2 Parameter list when the D bit is set to 1 and the NWDAF requests parameters from the UE

[0062] When the N1 parameter management message in the N1 parameter management message container is a subscription UE parameter message, the subscription UE parameter message also includes the threshold value of each parameter to be reported. When the parameter on the UE side exceeds the threshold value, the parameter reporting process is triggered. When the NWDAF subscribes to the UE, the parameter list format is as shown in Table 3 below:

[0063]

[0064] Table 3 Parameter list when the D bit is set to 1 and the NWDAF subscribes to the UE

[0065] In the above embodiment, the corresponding reporting method or reporting content is determined according to different types of N1 parameter management messages, and different parameter list formats are determined to provide a data format for parameter reporting.

[0066] In one embodiment, the information unit corresponding to the parameter list to be reported also includes a direction bit; if the direction bit is 1, it indicates that the parameter list is transmitted according to the downlink from the network side to the terminal side; if the direction bit is 0, it indicates that the parameter list is transmitted (reported) according to the uplink from the terminal side to the network side.

[0067] The direction bit is the D bit in Table 1 above. When the D bit is 1, it indicates from the network to the UE, and when it is 0, it indicates from the UE to the network. When the D bit is set to 1, if the NWDAF requests parameters from the UE, the parameter list format is as shown in Table 2 above. When the D bit is set to 1, if the NWDAF subscribes to parameters from the UE, the parameter list format is as shown in Table 3 above.

[0068] When the D bit is set to 0, it indicates that the UE responds to the NWDAF's request or subscription and reports parameters to the NWDAF, including immediate reporting, periodic reporting, and triggered reporting when the threshold condition is reached. The parameter list format is shown in Table 4:

[0069]

[0070] Table 4 Parameter list when the D bit is set to 0

[0071] In this embodiment, the D bit is introduced as a parameter transmission direction indicator so that the uplink and downlink can reuse the same parameter list information unit format.

[0072] In one embodiment, the parameter value or the analysis result regarding the parameter value is sent to the AF network element;

[0073] The AF network element subscribes to the UE parameter reporting event to the AMF, and the AMF sends a UE parameter reporting event notification to the AF after receiving the parameter list reported in the response message of the PM message sent by the UE;

[0074] or,

[0075] The AF network element subscribes to the analysis result from the network data analysis function network element, where the analysis result is derived by the network data analysis network element in combination with the parameters reported by the UE.

[0076] Furthermore, if the AF network element is in a trusted domain, the parameter value or the analysis result on the parameter value is directly sent to the AF network element; if the AF network element is in an untrusted domain, the analysis result is sent to the AF network element via the NEF network element.

[0077] Specifically, if Figure 2 As shown in steps 10-13:

[0078] 10. NWDAF uses the parameters reported by the UE to derive relevant analysis. NWDAF can use the parameters reported by the UE alone or in combination with information collected from other data sources (such as core network NF, OAM, etc.) to derive relevant analysis.

[0079] Steps 11-13: The application server AF can subscribe to the relevant analysis results from the NWDAF or directly obtain the UE parameters through the AMF's UE parameter reporting event open service:

[0080] 11. NWDAF can open relevant analysis results to AF. If AF is in a trusted domain, it can open directly; if AF is in an untrusted domain, it can open through NEF.

[0081] 12-13: AF can also subscribe to UE parameter reporting events to AMF directly or through NEF. After receiving the parameters carried in the PM NAS reported by the UE, AMF notifies the AF of the UE parameters through Namf_EventExposure_Notify (for simplicity, the step of AF subscribing to UE parameter reporting events to AMF is not shown in the figure).

[0082] The AF can directly subscribe to the analysis results from the NWDAF or directly obtain the parameters reported by the UE for processing. For example, in scenarios like XR, the AF can consider changing the codec or data rate based on the CDRX parameters and battery level reported by the UE to better balance the service experience and power conservation. It should be noted that there is no time sequence relationship between step 11 and steps 12-13; either or both can be performed.

[0083] In the above embodiment, the application server subscribes to the relevant analysis results from NWDAF or directly obtains the UE parameters through the UE parameter reporting event open service of AMF.

[0084] The following describes the device for collecting terminal information in a 5G network provided by the present invention.
