Embodiment 1

[0457] This example illustrates the implementation of NWDAF collecting data and generating user experience analysis of EC Application.

[0458] In order to generate a user experience analysis of EC Application deployed on the 3GPP network, NWDAF can collect relevant data from SMF and AF.

[0459] Data collected from SMF may include:

[0460]

[0461] Data collected from AF can include:

[0462]

[0463] NWDAF can correlate the data collected from SMF with the data collected from AF through timestamp and IP filter information. NWDAF uses machine learning algorithms to mine out the relationship between data, and the generated data analysis results can include the following:

[0464] Table 1: User experience analysis of EC Application (> indicates that there is an inclusion relationship between these table items)

[0465]

Embodiment 2

[0467] This example illustrates the implementation of NWDAF providing SMF with user experience analysis of each EC Application.

[0468] The data analysis content provided by NWDAF includes the content in Table 1. In addition, if the SMF requests user experience analysis, it can also request the NWDAF to directly provide Anchor UPF (anchor UPF) recommendation information that can guarantee user experience or service performance.

[0469] Figure 6 It is a schematic flow diagram of the NWDAF providing data analysis results to the SMF in Embodiment 2. As shown in the figure, based on the analysis provided by the NWDAF, the SMF can optimize the user plane path when the UE accesses the edge computing application. The flow can be as follows:

[0470] Step 601, PDU Session is established.

[0471] The UE creates a PDU session, and the carried S-NSSAI (Single-NetworkSlice Selection Assistance Information, Single-NetworkSlice Selection Assistance Information) and DNN indicate that t...

Embodiment 3

[0495] This example illustrates the implementation of NWDAF providing EC Application user experience analysis to AF.

[0496] The data analysis content provided by NWDAF includes the following:

[0497] Table 2: User experience analysis of EC Application (> indicates that there is an inclusion relationship between these table items)

[0498]

[0499] In addition, if the AF requests user experience analysis, it can also request the NWDAF to provide DNAI recommendation information that can guarantee user experience / service performance.

[0500] Figure 7 It is a schematic flow diagram of the NWDAF providing data analysis results to the AF in Embodiment 3. As shown in the figure, based on the analysis provided by the NWDAF, the AF can determine the optimal application server when the UE accesses the edge computing application. The flow can be as follows:

[0501] Step 701, PDU Session is established.

[0502] Step 702, Data Traffic.

[0503] The UE creates a PDU session, a...

Abstract

The invention discloses a method for determining a user plane function and providing information, equipment and a medium. The method comprises that: after receiving a data analysis request of a session management function and / or an application function about an application, a network data analysis function analyzes application operation data collected from the session management function and the application function to generate a user experience analysis result and / or a performance analysis result containing the location area of the UE, the location of the application and the location of a user plane anchor point, and a corresponding relationship with user experience analysis and / or performance analysis of the application; the data analysis result is provided for the session management function and / or the application function, so that the session management function can optimize the user plane path based on the analysis result; and the application function can adjust the position of the target application based on the analysis result. By adopting the invention, selection of the transmission path and the target service server can be considered from the perspective of user experience or service performance, and the user experience and the service performance are ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and medium for determining user plane functions and providing information. 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 network architecture. In the edge computing network architectu...
