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...

Abstract

The invention discloses an information providing method, a base station auxiliary information generating method, a target base station determining method and device, and a medium, and the method comprises the following steps: a network data analysis function receives a data analysis request of a core network function and/or a wireless access network node about an application; and the network data analysis function analyzes application operation data collected from the access and mobility management function and/or the session management function and/or the application function, and provides a data analysis result to the core network function and/or the wireless access network node, so that the core network function and/or the wireless access network node can select the target base station based on the analysis result. By adopting the scheme, in the switching decision process of the base station, the target base station can be selected by referring to the data analysis result, the selection is not only dependent on the measurement result of the air interface wireless signal any more, the target base station can be considered from the perspective of user experience or service performance, and the user experience and service performance are ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, equipment and medium for providing information, generating auxiliary information of a base station, and determining a target base station. Background technique [0002] Mobile edge computing technology migrates computing storage capabilities and business service capabilities to the edge of the network, eliminating the need to transmit data back to the cloud as much as possible, reducing the waiting time and network costs for data to and from the cloud. Based on the 5G distributed cloud infrastructure, the 5G user plane and 5G MEC (Mobile Edge Computing) nodes are built on the edge cloud. The 5G MEC nodes provide the MEC application platform to implement the deployment and management capabilities of third-party applications. Users can obtain services through MEC applications. [0003] figure 1 It is a schematic diagram of the edge computing netwo...
