Description

网络架构中网元之间的交互方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种网络架构中网元之间的交互方法及装置。
背景技术
为了保持第三代移动通信系统在通信领域的竞争力，为用户提供速率更快、时延更低、以及更加个性化的移动通信服务，同时，降低运营商的运营成本，第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)标准工作组正致力于演进分组系统(Evolved Packet System，简称EPS)的研究。
图1为相关技术中分组域系统的结构示意图，如图1所示，整个PS系统分为3G无线接入网和3G核心网两部分。
在3G无线接入网中，包含了基站(NodeB)和3G无线网络控制器(Radio Network Controller，简称为RNC)，它主要负责无线信号的收发，通过空中接口和终端联系，管理空中接口的无线资源、资源调度、以及接入控制。
在3G核心网中，包含了归属位置寄存器(Home Location Register，简称为HLR)、服务GPRS支持节点(Serving GPRS Support Node，简称为SGSN)、网关GPRS支持节点(Gateway GPRS Support Node，简称为GGSN)、策略和计费规则功能(Policy and Charging Rules Function，简称为PCRF)、在线计费系统(Online Charging System，简称为OCS)。
图2为相关技术中演进分组域系统的结构示意图，如图2所示，整个EPS系统分为4G无线接入网和4G核心网两部分。
4G无线接入网，包含了演进基站(Evolved NodeB，简称为eNodeB)，它主要负责无线信号的收发，通过空中接口和终端联系，管理空中接口的无线资源、资源调度、以及接入控制。
在4G核心网中，包含了归属用户服务器(Home Subscriber Server，简称为HSS)、移动性管理实体(Mobility Management Entity，简称为MME)、服务网关(Serving Gateway，简称为S-GW)和分组数据网关(PDN Gateway，简称为P-GW)、策略和计费规则功能(Policy and Charging Rules Function，简称为PCRF)、在线计费系统(Online Charging System，简称为OCS)。
在宽带领域，内容分发网络(Content Delivery Network，简称为CDN)通过在不同地点缓存内容，通过负载均衡等技术将用户请求定向到最近的缓存服务器上获取内容，提高用户访问网站的响应速度。CDN通过用户就近性和服务器负载的判断，以一种更为高效的方式为用户的请求提供服务。
为了充分利用CDN的优势，移动网络运营商希望将CDN部署在移动网络中，将CDN与 移动网络融合，加速移动用户的内容，提高响应速度，节约带宽。

其中，如果APN为激活RAN CDN功能的APN，则SGSN在DNS查询请求消息中，携带RNC ID，示例为internet.rnc0001.mnc021.mcc206.gprs。其中rnc0001为UE所在覆盖区域的RNC。
如果APN为不激活RAN CDN功能的APN，以黑莓为例，则SGSN在DNS查询请求消息中，携带APN，示例为blackberry.mnc021.mcc206.gprs。
步骤S1107，DNS Server向SGSN回答DNS查询响应(DNS Query Response)消息，携带RAN CDN地址。
其中，DNS Server的DNS解析文件，包含有一行RNC ID和RAN CDN的IP地址的对应关系的配置记录。举例如下：
internet.rnc0001.mnc021.mcc206.gprs IN A 10.5.155.28 //For RAN CDN APN
blackberry.mnc021.mcc206.gprs IN A 12.5.155.28 //For Non RAN CDN APN
步骤S1108，SGSN从DNS查询响应消息中获得RAN CDN地址，向选定的RAN CDN发送创建PDP请求(Create PDP Request)消息。
步骤S1109，RAN CDN向SES发送信用控制请求初始消息(Credit Control Request Initial，简称为CCR_I)。CCR消息，是RAN CDN基于Diameter协议，通过SES向PCRF系统发送的信用控制请求消息，申请PCRF对当前用户使用的业务进行信用控制。CCR_I消息，是会话建立的时候RAN CDN基于Diameter协议，通过SES向PCRF发送的会话初始化消息，主要功能是查询用户状态，申请策略控制。
步骤S1110，SES向PCRF发送CCR_I消息。
步骤S1111，PCRF开始进行策略控制。PCRF向SES回答信用控制应答初始消息(Credit Control Answer Initial，简称为CCA_I)。CCA消息，是PCRF基于Diameter协议，通过SES向RAN CDN发送的信用控制应答消息，RAN CDN根据CCA消息控制用户使用业务。CCA_I消息，主要功能是回答用户状态、进行策略控制。
