The flexible continuity guarantee is demanded for task-oriented user connection requests in satellite networks. In this paper, we propose a task-oriented satellite conditional handover scheme, D-CHO, based on multi-agent game theory. For the problem formalization, this paper focuses on delay overhead, satellite utilization deviation, and load performance to model the multi-objective optimization. According to game theory, a Nash equilibrium exists among the multi-task game strategies that require satellite links. Through exploration and exploitation, the optimal satellite handover sequence scheme can be identified. This paper explores the optimal solution based on the MAPPO algorithm, which enables multiple tasks to make independent decisions based on their partial observations without requiring global information. This approach is beneficial for the adaptive expansion in response to dynamic changes in different satellite networks. The simulation results show that D-CHO improves performance by 22%, 26%, and 11% compared to the SCDP, G-CHO, and MADDPG-CHO algorithms, respectively, and exhibits better scalability while maintaining satisfactory performance.<\/jats:p>","DOI":"10.3233\/faia250944","type":"book-chapter","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:46:39Z","timestamp":1761126399000},"source":"Crossref","is-referenced-by-count":0,"title":["D-CHO: Task-Oriented Satellite Conditional Handover Decision in NTN Based on Multi-Agent Game"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-7684-1065","authenticated-orcid":false,"given":"Lin","family":"Sun","sequence":"first","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinming","family":"Liu","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fanmeng","family":"Hong","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4535-5038","authenticated-orcid":false,"given":"Haopeng","family":"Chen","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiupu","family":"Lang","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Gui","sequence":"additional","affiliation":[{"name":"Shanghai Jiao Tong University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2025"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA250944","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:46:40Z","timestamp":1761126400000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA250944"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,21]]},"ISBN":["9781643686318"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia250944","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,21]]}}}
