Examples
Embodiment 1
[0127] In this example, the c-NWDAF sends a data analysis subscription request to the designated d-NWDAF according to the request of the consumer NF (consumer NF).
[0128] Image 6 It is a schematic diagram of the implementation process of subscription processing in Embodiment 1, as shown in the figure, which may include:
[0129] 1. c-NWDAF receives the analysis request (Analytics Request) sent by the consumer NF, where the analysis request carries the analytics ID and filter conditions, including the area of interest (area of interest), UE ID, etc. The c-NWDAF queries the NRF according to the Area of interest to obtain the d-NWDAF list currently serving the area, and queries the UDM according to the UE ID to obtain the 5GC NF (AMF or SMF) currently serving the UE. For details, reference may be made to relevant implementation manners in the prior art.
[0130] 2. The c-NWDAF determines the d-NWDAF associated with it according to the 5GC NF (AMF / SMF) currently serving...
Embodiment 2
[0137] In this example, the c-NWDAF instructs the d-NWDAF to suspend the data analysis request according to the request of the consumer NF.
[0138] Figure 7 It is a schematic diagram of the implementation process of subscription processing in Embodiment 2, as shown in the figure, which may include:
[0139] 1-2, can refer to embodiment 1.
[0140] 1. The c-NWDAF receives the analysis request sent by the consumer NF, where the analysis request carries the analytics ID and filter conditions, including the area of interest (area of interest), UE ID, etc. c-NWDAF queries NRF (Network Repository Function) according to Area of interest to obtain the d-NWDAF list currently serving the area, and queries UDM according to UE ID to obtain the 5GC NF (AMF or SMF) currently serving UE. For details, reference may be made to the implementation of the prior art.
[0141] 2. The c-NWDAF determines the associated d-NWDAF according to the 5GC NF (AMF / SMF) currently serving the UE, whi...
Embodiment 3
[0149] In this example, the UE notifies the c-NWDAF after moving out of the current d-NWDAF service range.
[0150] Figure 8 It is a schematic diagram of the implementation process of subscription processing in Embodiment 3, as shown in the figure, which may include:
[0151] 1-2. The c-NWDAF requests the UE's data analysis result Nnwdaf_AnalyticsSubscription_Subscribe / Notify from the serving d-NWDAF. Therefore d-NWDAF1 performs data collection (Datacollection) and data analysis. For details, reference may be made to the implementation of the prior art.
[0152] 3. When the UE moves out of the service range of the serving d-NWDAF1, the serving d-NWDAF needs to report to the c-NWDAF. The serving d-NWDAF determines that the UE moves out of its serving area (UE moves out of d-NWDAF1 serving area) according to the 5GC NF information provided in the Nudm_SDM_Notification sent by UDM or the event report of the 5GC NF in the data collection report. When the serving d-NWDAF repor...
