摘　　要：基于5G CU分离架构,结合5G ULCL分流技术,建设政务外网双网双域5G专网,实现人(2C)和物(2B)“双网”接入,内网(政务外网)和外网(互联网)“双域”访问。对接AAA服务器实现二次认证,强化5G接入安全,建设一网多平面的5G+政务外网架构。双网双域5G专网融合固网接入,解决了“最后一公里”的末端接入问题。Based on the 5G CU separation architecture,combined with the 5G ULCL offloading technology,a dual-network and dual-domain 5G private network for government extranet is constructed to realize the "dual network" access of people(2C)and things(2B),and the "dual domain" access of the internal network(government affairs net)and the external network(Internet).It connects with AAA server to achieve secondary authentication,strengthens 5G access security,and builds a 5G government extranet architecture with one network and multiple planes.The dual-network and dual-domain 5G private network integrates fixed network access,solves the "last mile" end access problem.
