Problems solved by technology

[0003] However, the associated backfill technology based on the N9 interface in the prior art is generally realized by collecting the data of the N4 interface between the SMF network element and the PDU session anchor point and relying on the network element. However, since the user information carried in N4 is not comprehensive, the When performing associated backfilling, the associated user information will be missing, which will affect the accuracy of the associated backfilling results

Abstract

Embodiments of the present invention disclose a 5G core network-based user information association backfill method, device, equipment and medium. The method includes: acquiring user information and N3 network elements by collecting session messages of AMF network elements and SMF network elements in an N11 interface. The first correspondence between the UPF identifiers corresponding to the interfaces; the second correspondence between the UPF identifiers corresponding to the N3 interface and the UPF identifiers corresponding to the N9 interface is obtained by collecting the session messages of the SMF network element and the UPF network element in the N4 interface; User information is searched according to the UPF identifier corresponding to the N9 interface, the second corresponding relationship and the first corresponding relationship, and the user information is associated with the user operation behavior and backfilled. By collecting the conversation messages between AMF and SMF and between SMF and UPF, the corresponding relationship of user information query is established, so that when the user operation behavior of the N9 interface is obtained, the user information association of N9 user plane data is guaranteed based on the above corresponding relationship. The comprehensiveness of user information during backfilling improves the accuracy of associated backfilling results.

Description

technical field [0001] Embodiments of the present invention relate to the field of 5G communications, and in particular, to a method, apparatus, device, and medium for backfilling user information associated with a 5G core network. Background technique [0002] With the rapid development of the 5G industry, operators are currently deploying 5G standalone (SA) networks on a large scale. In the SA network architecture, the user plane and control plane of the 5G core network are completely separated, and in edge computing scenarios The user data needs to be offloaded, and the private network traffic will be offloaded to the edge private network. At this time, an N9 interface will be added to transmit the large network traffic to the operator side. In this scenario, the Access and Mobility Management Function (AMF) network elements and the Session Management Function (SMF) network elements connected through the N11 interface are connected to the user plane through the N4 interfa...
