摘要
面向5G政务专网应用场景,在梳理典型业务需求的基础上,整合形成了基于终端号卡分流、DNN分流和UL CL分流3类解决方案,并指出其主要优势、局限性和场景适用性。最后针对现有UL CL方案的不足,提出了UL CL随行漫游和2B、2C融合优化思路。
For 5G government private network application scenarios,three types of traffic offloading solutions based on SIM card,DNN and UL CL technologies are integrated and formed on the basis of sorting out typical service requirements.Then,all of these solutions' main advantages,limitations and scenario applicability are pointed out.Finally,aiming at the shortcomings of existing UL CL schemes,an optimization idea of UL CL accompanying roaming and 2B,2C fusion is proposed.
