In this article, we present a novel user-centric service provision for immersive communications (IC) in 6G to deal with the uncertainty of individual user behaviors while satisfying unique requirements on the quality of multi-sensory experience. To this end, we propose a data-oriented approach for network resource management, featuring personalized data management that can support network modeling tailored to different user demands. Our approach leverages the digital twin (DT) technique as a key enabler. Particularly, a DT is established for each user, and the data attributes in the DT are customized based on the characteristics of the user. The DT functions, corresponding to various data operations, are customized in the development, evaluation, and update of network models to meet unique user demands. A trace-driven case study demonstrates the effectiveness of our approach in achieving user-centric IC and the significance of personalized data management in 6G.

翻译：本文提出了一种面向6G沉浸式通信的新型用户中心化服务供给方案，旨在应对个体用户行为的不确定性，同时满足多感官体验质量的独特需求。为此，我们提出了一种面向网络资源管理的数据驱动方法，其核心特征为支持按需网络建模的个性化数据管理。本方案以数字孪生技术作为关键使能手段：为每个用户建立专属数字孪生体，并基于用户特征定制数字孪生内的数据属性。对应于不同数据操作的数字孪生功能，将在网络模型的开发、评估与更新过程中进行定制化设计，以满足用户的个性化需求。基于真实数据轨迹的案例研究表明，本方案能有效实现用户中心化的沉浸式通信，并验证了个性化数据管理在6G系统中的重要意义。
