TR-069 协议完整的通信过程
TR-069协议完整的通信过程
以下为设备重启到挂上TR069网管的报文流程解析
- (1) 设备启动；根据配置的ACS(自动配置服务器)地址，建立安全的HTTP连接以后，每次连接CPE都必须首先对ACS发出一个Inform的RPC调用请求来向ACS汇报本次连接的信息。ACS会返回给一个Inform response作为确认连接。
标准的Inform方法的参数如表所示
| 参数名称 | 参数说明 |
|---|---|
| DeviceID | 数据结构标识CPE |
| Event | 标识此次Inform发起的原因 |
| MaxEnvelopes | HTTP Response可携带SOAP信封数 |
| CurrentTime | CPE当前的时间 |
| RetryCount | 这次Session最大的重复连接次数 |
| ParameterList | 这次Inform所需携带的参数 |

TR069协议簇的其他规范
TR069协议不仅仅包括TR-069子协议，还包括其他一些的协议，构成了一个完整的网管协议簇。与之配套的TR-098协议和TR-104协议分别定义了CPE的数据业务的管理参数和VoIP业务的管理参数，WT-135协议用于定义数字机顶盒的管理参数，TR-111协议定义了在家庭内部数字设备上实施TR069网管的机制，WT-121协议则是各个厂家在实现和部署TR069过程中对协议的修订。
