In such virtualized cellular networks, the load on UPF, which is responsible for the U-Plane function, varies depending on user traffic, so scaling according to the load is considered necessary for the efficient use of computing resources. On the other hand, when considering scale-in in particular, simple scale-in may cause delays and losses in user traffic. Therefore, in this paper, we propose to introduce a function to dynamically switch GTP tunnels between gNBs and UPF in gNBs to achieve seamless traffic switching.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2024-CSEC-104"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233229,"links":{}}
