| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In 5G Core Network (5GC) deployment services, network functions maintain UE context information. This adds complexity to the 5G network architecture and causes major breakdown when problems occur. To resolve this problem, in previous research, we proposed stateless 5GC, which enables stateless procedural processing. In this procedural 5GC, the state is removed from the 5GC Procedure by storing and restoring a UE context used in each NF to the external storage. In this paper, we describe the design of Proc5GC ORM, which stores and restores UE contexts in external storage using Proc5GC. Then, we performed I/O to the external database using Proc5GC ORM and evaluated the performance when many UEs access the same time. | |
