Description

一种用户文本感知业务的处理方法及网络设备 技术领域
本申请涉及但不限于移动通信领域，尤指一种用户文本感知业务的处理方法及网络设备。
背景技术
图1为长期演进系统(Long Term Evolution，简称LTE)的总体架构示意图，如图1所示，LTE架构包括：移动管理实体(Mobility Management Entity，简称MME)，服务网关(Serving GateWay，简称SGW)，用户设备或称为终端(User Equipment，简称UE)和基站(eNodeB，简称为eNB)之间是UU接口，eNB和MME之间是S1-MME(S1for the control plane，控制面S1)接口，eNB和SGW之间是S1-U接口，eNB之间是X2-U(X2-User plane，用户面X2)和X2-C(X2-Control plane，控制面X2)接口。在LTE中，S1-MME接口的协议栈从下往上分为以下几个协议层：L1协议，L2协议，因特网协议(Internet Protocol，简称IP)，流控制传输协议(Stream Control Transmission Protocol，简称SCTP)，S1应用协议(S1-Application Protocol，简称S1-AP)。在LTE中，S1-U接口的协议栈从下往上分为以下几个协议层：L1协议，L2协议，用户数据协议/因特网协议(UDP/IP)，GPRS隧道协议-用户面(GPRS Tunneling Protocol-User plane，简称GTP-U)。
同时，随着通信技术的发展，到了物联网时代，未来的数百亿物体均要接入网络。不同的终端接入移动网络而对服务的需求也不尽相同，具备了允许应用软件开发本地内容和实时信息的本地接入网络的条件。运营商网络中的业务模型从传统单一的语音和短信业务，演变为多样化的互联网业务。多样化的业务模型对运营商的网络运营、维护优化带来新的挑战，如何保障多样化业务的业务体现，满足用户的感知需求，将成为未来运营商竞争的核心问题。
CDN(Content Delivery Network，内容分发网络)技术通过在已有的Internet中增加一层新的网络架构，将网站的内容发布到最接近用户的网络“边缘”(边缘服务器)，使用户可以就近取得所需的内容，解决Internet 网络拥挤的状况，提高用户访问网站的响应速度。从技术上全面解决由于网络带宽小、用户访问量大、网点分布不均等原因所造成的用户访问网站响应速度慢的问题。CDN网络架构主要由两大部分组成，分为中心和边缘两部分，中心指CDN网管中心和DNS(Domain Name System，域名解析服务器)重定向解析中心，负责全局负载均衡，设备系统安装在管理中心机房；边缘主要指异地节点，CDN分发的载体，主要由Cache(缓存)和负载均衡器等组成。
简单地说，CDN是一个经策略性部署的整体系统，包括分布式存储、负载均衡、网络请求的重定向和内容管理4个要件。使用了CDN服务后，用户的访问流程包括如下步骤：
步骤1：用户向浏览器提供要访问网站的域名，域名解析的请求被发往网站的DNS；
步骤2：由于网站的DNS对此域名的解析设置了CNAME(规范名字)，请求被指向CDN网络中的智能DNS负载均衡系统；
步骤3：智能DNS负载均衡系统对域名进行智能解析，将响应速度最快的节点IP(Internet Protocol，互联网协议)返回给用户；
步骤4：浏览器在得到速度最快节点的IP地址以后，向CDN节点发出访问请求；
步骤5：由于是第一次访问，CDN节点将回到源站点取用户请求的数据并发给用户；
步骤6：当有其他用户再次访问同样内容时，CDN将直接将数据返回给客户，完成请求/服务过程。
上述流程只适用于IP数据，无法适用目前3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)系统下的业务管理模型。
