LEO satellites, positioned in low orbits, enable low-latency communication; however, their limited coverage necessitates the deployment of large-scale satellite constellations. Due to constraints on the number of satellites in the early stages of business operations, service availability in terms of geographic coverage and time is limited, posing a challenge in securing users. This paper proposes a cooperative service provision model involving multiple LEO satellite operators and introduces a revenue-sharing scheme based on the Shapley value from cooperative game theory. Furthermore, we conduct a numerical evaluation to assess the potential for service expansion through inter-operator cooperation.","subitem_description_type":"Other","subitem_description_language":"en"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2025-IOT-68"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2000693,"updated":"2025-07-07T04:05:30.899666+00:00","links":{}}
