Embodiment 1
[0474] This example illustrates the implementation of NWDAF collecting data and generating UE's EC Application user experience analysis.
[0475] In order to generate a user experience analysis of EC Application deployed on the 3GPP network, NWDAF can collect relevant data from AMF, SMF or AF.
[0476] The data collected from AMF includes: (> indicates that there is an inclusion relationship between these entries)
[0477] Information Description UE ID UE's identity, such as SUPI UE locations(1..max) UE location >UE location The location of the UE, which can be represented by TA or cell >RAN node ID RAN node identity serving UE >Timestamp Timestamp of the UE at the specified location
[0478] Data collected from SMF includes:
[0479]
[0480] Data collected from AF includes:
[0481]
[0482] NWDAF can associate the data collected from SMF with the data collected from AF through timestamp and IP filter information; us...
Embodiment 2
[0486] In this example, the AMF subscribes to the UE's EC Application user experience analysis from the NWDAF and generates auxiliary parameters.
[0487] Figure 7 A schematic flow diagram of the data analysis results provided by the NWDAF to the AMF in Embodiment 2, as shown in the figure, may include the following steps:
[0488] Step 701, UE registers with the network.
[0489] Step 702, establish a PDU session.
[0490] Step 703, Nnwdaf_AnalyticsSubscription_Subscribe (Nnwdaf_AnalyticsSubscription Subscribe).
[0491] Step 704, Nnwdaf_AnalyticsSubscription_Notify (Nnwdaf_Analytics Subscription Notify).
[0492] When the AMF determines that the S-NSSAI and DNN used by the PDU session established by the UE support edge computing, the AMF subscribes to the NWDAF for the user experience analysis of the UE's edge computing application.
[0493] AMF sends a subscription request to NWDAF, and the subscription request can carry data analysis filter conditions, such as S-NSSAI...
Embodiment 3
[0503] This example illustrates the implementation of user experience analysis of a specified EC Application subscribed by AMF to UE.
[0504] Figure 8 A schematic flow diagram of the data analysis results provided by the NWDAF to the AMF in Embodiment 3, as shown in the figure, may include the following steps:
[0505] Step 801, establish a PDU session.
[0506] The UE registers with the network and establishes a PDU session.
[0507] Step 802, Nsmf_EventExposure_Subscribe (Nsmf_event exposure subscription).
[0508] Step 803, Application relocation (application relocation).
[0509] Step 804, Nsmf_EventExposure_Notify (Nsmf_event exposure notification).
[0510] When the AMF determines based on the network configuration information that the S-NSSAI and DNN used by the PDU session established by the UE support edge computing, the AMF subscribes to the SMF for the EC Application information used by the UE.
[0511]The SMF obtains the EC Application information accessed b...
