AI Technical Summary
Existing technologies cannot establish local area networks across core networks, especially in low-Earth orbit satellite networks, where static configurations cannot meet dynamic requirements due to the dynamic changes in the UPF.
The first session management function (SMF) sends SMF information of the first user equipment to the application function and receives network group SMF information of the virtual network group, including the second SMF information of the second user equipment. Then, it sends the information of the first user plane function (UPF) to the second SMF of the second user equipment and receives the information of the second UPF, thereby realizing tunnel interoperability between UPFs.
It enables the establishment of a local area network across the core network in a low-Earth orbit satellite network, ensuring the utilization rate and service quality of network resources, enhancing the flexibility and dynamic adaptability of the system, reducing the complexity of operation and maintenance, and improving the practicality and competitiveness of the network in NTN scenarios.
