校园5G专网的设计与实现

Design and implementation of 5G campus private network

目前校园网存在明确的地域边界,应用限制在校园网内部,外部用户需要通过各种VPN系统接入校园网,存在使用不便性能下降的问题;其次,校园内移动终端接入校园网需要大量WiFi设施,投资大效果一般。利用5G网络高速率、低时延和高并发的特点,使用UPF分流技术构建校园5G融合专网,将访问校园网的数据通过5G融合网关到达校园网,扩展校园网边界,二次鉴权系统保证校园网接入安全,实现了大规模移动终端和物联网设备接入校园网,具备投资少性能好的优势。测试表明校园5G专网用户与校内用户体验一致,使用方便且性能优良。

At present,there are clear geographical boundaries in the campus network,which is only available for internal users.External users who want to access the campus network need to connect the network through various VPN systems,which cause inconvenient use and reduced performance.In addition,mobile terminals on campus require a large amount of WiFi facilities to access the campus network,which needs large investment but the effect is not satisfactory.Considering the advantages of 5G network,namely,high speed,low latency,and high concurrency,it is advisable to use UPF diversion technology to construct a 5G campus fusion private network,which can transmit the data accessing the campus network through 5G fusion gate and expand the boundaries of the campus network.The secondary authentication system ensures the security of campus network access,which cannot only realize the integration of large-scale mobile terminals and IoT devices into the campus network,but also reduce investments and get good performance.The test shows that the experience of campus 5G private network users is consistent with that of on campus users,which is convenient to use and has excellent performance.
