关于5G双域快网的实现方案

Implementation Plan for 5G Dual Domain Fast Network

中国电信5G双域快网,是指在5G定制网的“比邻”模式下,基于中国电信边缘UPF设备,为特定用户(指行业客户的特定群体,如师生、政务员工、医护人员等)和非特定用户(指到访客户指定的特定区域的所有电信5G用户,如普通游客)提供数据流量本地卸载和就近处理,使中国电信5G移动业务用户、物联网5G用户不换卡、不换号,可同时访问客户内网和互联网。文章主要说明5G双域快网基于增强型ULCL分流方式和DNN分流方式,实现4G和5G网络均可以访问客户内网和互联网的功能,同时增加域名分流和DNS重定向的方案以实现附加的功能。

China Telecom 5G dual domain fast network refers to the neighboring mode of the 5G customized network,based on China Telecom edge UPF devices,providing local offloading and processing of data traffic for specific users(referring to spccific groups of industry customcrs,such as teachers and students,government cmployccs,medical staff,etc.)and non-specific users(referring to all telecom 5G users visiting spccific arcas designated by customers,such as ordina-ry tourists),cnabling China Telecom 5G mobile business users 5G users of the Internet of Things do not change their cards or numbers,and can access both the customer's intranet and in-ternet simultaneously.This paper mainly explains that the 5G dual domain fast network based on enhanced ULCL and DNN shunting methods,achieving the function of both 4G and 5G net-works accessing customers internal networks and the internet.At the same time,a solution for domain name shunting and DNS redirection is added to achieve additional functions.
