摘要
传统校园网络用户存在难以接入校园内网、访问校园内网数据资源易断开、需要频繁切换等问题,在5G SA网络能够灵活组网满足不同差异化需求的情况下,希望能够基于5G网络,在校园内外的任何地方使用移动终端通过5G网络安全方便地访问校园内外的网络。部署基于专用DNN的5G双域专网的校园网,只要校园用户完成在网络中的签约,就可以实现基于5G大带宽和低时延的安全高效校园内网资源访问,同时还可以根据应用场景访问公共网络,不影响内网的访问。经信令跟踪并分析验证,5G双域专网技术方案能实现高校用户的4G/5G融合场景下省内/省际漫游下内外网流量的无感切换。通过在某高校5G双域专网的部署验证成功,证明5G双域专网应用解决方案能够满足绝大多数5G专网内外网访问的业务需求。
Traditional campus network users have problems such as difficulty accessing the campus Intranet,easily disconnecting data resources from the campus intranet,and frequent switching.As 5G SA networks have been able to flexibly network to meet differentiated needs,mobile terminals are expected to securely and conveniently access networks on and off campus via 5G networks anywhere on and off campus.After the campus network deployment of the 5G dual-domain private network based on private DNN is completed,campus users can access campus intranet resources with large bandwidth and low delay based on 5G as long as they sign a contract with the network.At the same time,they can access public networks according to application scenarios without affecting intranet access.Through signaling tracing,it has been verified that the 5G dual-domain private network scheme can enable campus users to realize non-sensible switching of internal and external network traffic under intraprovincial/inter-provincial roaming in the 4G/5G fusion scenario.Through the deployment of a 5G dual-domain private network in a university,it is effectively verified that it can meet the vast majority of the business needs of network access inside and outside the 5G private network.
