Design and implementation of 5G network user interface function selection method based on knowledge map
Qing Huang Huang, Sun Qibo Sun · 2022
The UPF (user plane function) in 5G core network carries the user data of 5G mobile communication system, so flexible and reasonable UPF selection is of great significance. Aiming at the problem of insufficient flexibility and low efficiency of UPF selection in 5G core network, this paper proposes a UPF selection method based on knowledge graph, and implements and tests the method based on Mininet platform. The measure is the time the user sets up the PUD session. The results show that in different edge computing scenarios, the UPF selection method based on knowledge graph can meet the specific needs, improve the flexibility and efficiency of UPF selection, and reduce the signaling interaction process.
