针对大连理工大学城市学院的5G应用需求,设计了一种基于“5G+教育”的双域DNN专网规划方案。用户可以通过线上/线下渠道自主申请5G专网服务,实现无缝访问校园内外资源,显著提升用户体验。通过校园—5G RADIUS与运营商—5G RADIUS的双重鉴权和信息同步机制,实现了对5G专网用户的实时化、自动化、精细化管理,确保了用户能够安全、可信、可溯源且分级分权访问资源。5G RADIUS与校园统一身份管理平台的对接,实现了用户账户全生命周期管理,极大提高了网络管理的效率和透明度。该方案通过融合校园网认证与5G网络,致力于打造城院5G校园专网,实现了校园用户随时随地安全访问内网,为其他高校在5G专网建设方面提供了理论参考和实践指导。

In response to the 5G application requirements of Dalian University of Technology City College, this paper designs a dual-domain Dedicated Network Name (DNN) private network planning scheme based on "5G+Education". Users can independently apply for 5G private network services through online and offline channels, achieving seamless access to both on-campus and off-campus resources, and significantly enhancing the user experience. Through the dual-authentication and information synchronization mechanism between the users-5G RADIUS and the telcos-5G RADIUS, real-time, automated, and refined management of 5G private network users is realized, ensuring that users can access resources securely, reliably, and traceably at different privilege levels. The integration of 5G RADIUS with the campus-wide identity management platform has enabled unified collection and traceability management of internet usage and data traffic, greatly improving the efficiency and transparency of network administration. By integrating campus network authentication with 5G technology, this plan aims to create a 5G campus private network for City College, enabling campus users to access the internal network securely from anywhere and at any time, and also providing theoretical references and practical guidance for other universities in the construction of 5G private networks.
