Description

Data acquisition method, device, equipment, network system, medium and program product Technical Field The present application relates to the field of communications networks, and in particular, to a data acquisition method, apparatus, device, network system, medium, and program product. Background In 5G private network park deployment, a "shared UPF park" where the core network is not sinking is a widely adopted model for cost reduction. Under this architecture, the terminals and the base stations are deployed in the enterprise campus, the user plane function UPF is usually located at the city side, and the control plane network elements such as the access and mobility management function AMF, the session management function SMF, and the unified data management UDM are centralized at the provincial side. This distributed architecture reduces the hardware deployment and maintenance costs on the enterprise side, but also presents challenges for operation and maintenance monitoring of the campus network. In the prior art, there are mainly two schemes for data collection for such shared UPF parks. The first is a network management system that relies on each network element itself. The method has low cost, but the data is scattered, each network element only collects the index of the network element, and the network element lacks an integral view of an opposite end-to-end service link, so that the cross-domain fault is difficult to quickly locate. And secondly, the deep packet inspection equipment is widely deployed on each key node (such as N1, N2, N3, N4, N6 and other interfaces) of the signaling plane and the user plane to collect and analyze the flow. The scheme can provide comprehensive data, but has the obvious defects that firstly, the cost of multipoint deployment DPI equipment is high, along with the rapid increase of the number of 5G private network cards, the required storage and processing resources are huge, secondly, the signaling efficiency of filtering specific single cards from mass data is low, the operation and maintenance requirements of enterprises on specific fault scenes (such as offline cards and arrearages) are not met, and finally, the traffic mirror image can cause additional delay to a high-load network. Therefore, in view of the above situation, there is an urgent need to provide a data acquisition networking method based on a 5G private network with no sinking of the core network, so as to overcome the shortcomings in the current practical application. Disclosure of Invention The technical scheme of the application aims to provide a data acquisition method, a device, equipment, a network system, a medium and a program product, which are used for realizing centralized and effective monitoring of the network flow and the terminal state of a shared UPF park with the lowest deployment cost.
