TR-069 協議完整的通訊過程

TR-069協議完整的通訊過程

以下為裝置重啟到掛上TR069網管的報文流程解析 (1) 裝置啟動；根據配置的ACS(自動設定伺服器)地址，建立安全的HTTP串連以後，每次串連CPE都必須首先對ACS發出一個Inform的RPC調用請求來向ACS彙報本次串連的資訊。ACS會返回給一個Inform response作為確認串連。

標準的Inform方法的參數如表所示

參數名稱	參數說明
DeviceID	資料結構標識CPE
Event	標識此次Inform發起的原因
MaxEnvelopes	HTTP Response可攜帶SOAP信封數
CurrentTime	CPE當前的時間
RetryCount	這次Session最大的重複串連次數
ParameterList	這次Inform所需攜帶的參數

(2) ACS伺服器接受到裝置端(CPE端)發出的inform訊息之後，會給予一個 informresponse響應機cwmp串連建立成功

HTTP/1.1 200 OKDate: Tue, 02 Aug 2011 03:20:53 GMTServer: Microsoft-IIS/6.0X-Powered-By: ASP.NETX-AspNet-Version: 2.0.50727Set-Cookie: SerialNumber=00100400RJ0100100000001AA9800003; path=/Cache-Control: privateContent-Type: text/xml;charset=UTF-8Content-Length: 522<!-- 對裝置端inform訊息的響應即接受串連請求 --><soap:Envelope  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:cwmp="urn:dslforum-org:cwmp-1-0"  xmlns:xsd="http://www.w3.org/2001/XMLSchema"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">  <soap:Header>    <cwmp:ID soap:mustUnderstand="1">946684824</cwmp:ID>    <cwmp:HoldRequests soap:mustUnderstand="1">0</cwmp:HoldRequests>  </soap:Header>  <soap:Body>    <!-- ACS接受裝置端(cpe)端的inform請求(即建立cwmp串連的請求) -->    <cwmp:InformResponse>      <MaxEnvelopes>1</MaxEnvelopes>    </cwmp:InformResponse>  </soap:Body></soap:Envelope>

(3) 裝置端發送空訊息，表示沒有後續的請求

POST /service.tr069 HTTP/1.1Host: 183.62.12.23:8012  User-Agent: cwmpContent-Type: text/xml; charset=utf-8Connection: keep-aliveCookie: SerialNumber=00100400RJ0100100000001AA9800003;path=/Content-Length: 0<!-- Host: ACS(自動設定伺服器)地址 --><!-- Cookie: 設定在裝置的序號--><!-- Content-Length: 訊息內容長度為0代表空訊息-->

(4) ACS伺服器收到空訊息後，根據空訊息中攜帶的序號對裝置進行合法性驗證，若驗證通過則進行後續操作，若不通過則下發訊息提示裝置非法。序號的判斷在ACS內部判斷，未體現在報文中

(5) ACS驗證裝置序號合法，發送訊息要求裝置端上報網管的帳號資訊

HTTP/1.1 200 OKDate: Tue, 02 Aug 2011 03:20:53 GMTServer: Microsoft-IIS/6.0X-Powered-By: ASP.NETX-AspNet-Version: 2.0.50727Set-Cookie: SerialNumber=00100400RJ0100100000001AA9800003; path=/Cache-Control: privateContent-Type: text/xml;charset=UTF-8Content-Length: 658<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cwmp="urn:dslforum-org:cwmp-1-0"  xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">  <soap:Header>    <cwmp:ID soap:mustUnderstand="1">1</cwmp:ID>    <cwmp:HoldRequests soap:mustUnderstand="1">0</cwmp:HoldRequests>  </soap:Header>  <soap:Body>    <!-- 請求的方法為GetParameterValues，擷取裝置端的參數資訊 -->    <cwmp:GetParameterValues>      <ParameterNamesSOAP-ENC:arrayType="xsd:string[2]">        <!-- 擷取裝置TR069網管使用者名稱 -->        <string>Device.ManagementServer.Username</string>        <!-- 擷取裝置TR069網管密碼 -->        <string>Device.ManagementServer.Password</string>      </ParameterNames>    </cwmp:GetParameterValues>  </soap:Body></soap:Envelope>

(6) 裝置端接收該ACS伺服器請求上報帳號的訊息後，將發送裝置上配置的帳號資訊作為請求的響應

HTTP/1.1Host: 183.62.12.23:8012User-Agent: cwmpContent-Type: text/xml; charset=utf-8Connection: keep-aliveCookie: SerialNumber=00100400RJ0100100000001AA9800003;path=/Content-Length: 828SOAPAction: ""<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cwmp="urn:dslforum-org:cwmp-1-0">  <SOAP-ENV:Header>    <cwmp:ID SOAP-ENV:mustUnderstand="1">1</cwmp:ID>  </SOAP-ENV:Header>  <SOAP-ENV:Body>    <!-- 將帳號資訊作為ACS請求的響應訊息 -->    <cwmp:GetParameterValuesResponse>            <ParameterList xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="cwmp:ParameterValueStruct[2]">        <ParameterValueStruct>          <!-- 設定在裝置上的網管使用者名稱 -->          <Name>Device.ManagementServer.Username</Name>          <!-- 使用者名稱的具體值 -->          <Value>66661160</Value>        </ParameterValueStruct>        <ParameterValueStruct>          <!-- 設定在裝置上的網管密碼 -->          <Name>Device.ManagementServer.Password</Name>          <!-- 密碼的具體值 -->          <Value>66661160</Value>        </ParameterValueStruct>      </ParameterList>    </cwmp:GetParameterValuesResponse>  </SOAP-ENV:Body></SOAP-ENV:Envelope>

(7) ACS伺服器收到訊息後，根據訊息中攜帶的帳號資訊進行合法性驗證，若驗證通過則進行後續操作，若不通過則下發訊息提示帳號非法。序號的判斷在ACS內部判斷，未體現在報文中

(8) ACS驗證帳號合法，發送訊息要求裝置從特定URL上下載設定檔

HTTP/1.1 200 OKDate: Tue, 02 Aug 2011 03:21:04 GMTServer: Microsoft-IIS/6.0X-Powered-By: ASP.NETX-AspNet-Version: 2.0.50727Set-Cookie: SerialNumber=00100400RJ0100100000001AA9800003; path=/Cache-Control: privateContent-Type: text/xml;charset=UTF-8Content-Length: 856<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cwmp="urn:dslforum-org:cwmp-1-0" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">  <soap:Header>    <cwmp:ID soap:mustUnderstand="1">1</cwmp:ID>    <cwmp:HoldRequests soap:mustUnderstand="1">0</cwmp:HoldRequests>  </soap:Header>  <soap:Body>    <cwmp:Download>      <CommandKey>M Download</CommandKey>      <!-- 檔案類型 設定檔-->      <FileType>3 Vendor Configuration File</FileType>      <!-- 設定檔的URL地址，裝置端從該地址擷取設定檔並自動載入裝置 -->      <URL>http://183.62.12.23:8012/Config.aspx?ID=00100400RJ0100100000001AA9800003</URL>      <Description></Description>      <Username></Username>      <Password></Password>      <FileSize>0</FileSize>      <TargetFileName>ConfigFile.xml</TargetFileName>      <DelaySeconds>0</DelaySeconds>      <SuccessURL></SuccessURL>      <FailureURL></FailureURL>    </cwmp:Download>  </soap:Body></soap:Envelope>

(9) 裝置接收到該訊息之後，並根據訊息中的URL地址下載設定檔並自動設定，同時給ACS伺服器一個下載成功的響應訊息

Host: 183.62.12.23:8012User-Agent: cwmpContent-Type: text/xml; charset=utf-8Connection: keep-aliveCookie: SerialNumber=00100400RJ0100100000001AA9800003;path=/Content-Length: 484SOAPAction: ""<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cwmp="urn:dslforum-org:cwmp-1-0">  <SOAP-ENV:Header>    <cwmp:ID SOAP-ENV:mustUnderstand="1">1</cwmp:ID>  </SOAP-ENV:Header>  <SOAP-ENV:Body>    <!-- 通過該訊息告知ACS伺服器裝置成功擷取設定檔 -->    <cwmp:DownloadResponse>      <!-- 成功下載的狀態代碼 -->      <Status>1</Status>    </cwmp:DownloadResponse>  </SOAP-ENV:Body></SOAP-ENV:Envelope>

(10) ACS伺服器發送訊息，要求裝置從特定的URL下載升級檔案(是否升級可由使用者自行決定)

HTTP/1.1 200 OKDate: Tue, 02 Aug 2011 03:21:04 GMTServer: Microsoft-IIS/6.0X-Powered-By: ASP.NETX-AspNet-Version: 2.0.50727Set-Cookie: SerialNumber=00100400RJ0100100000001AA9800003; path=/Cache-Control: private
