[置顶] 【GBT28181开发:SIP协议实践】之设备远程启动

下面学习的是设备远程控制的流程,和设备信息、设备目录、设备状态的流程差不多,主要是描述的协议字段不同,模拟SPVMN系统向源设备发送远程启动控制指令,记录下交互的消息,详细研究了下:

一.环境搭建:

环境准备:http://blog.csdn.net/longlong530/article/details/9176989

UAC(模拟IPC):

IP:192.168.10.177(同事人不在~,直接用自己的机子模拟了下)

Port:5061


UAS(模拟SIP服务器):

 

IP:192.168.10.177

Port:5060


SPVMN操作过程:
1.先选择调测设备类型
3.点击设备远程启动,会在左边的文本框中显示xml。
<?xml version="1.0"?>
<Control>
<CmdType>DeviceControl</CmdType>
<SN>17298</SN>
<DeviceID>34020000001320000001</DeviceID>
<TeleBoot>Boot</TeleBoot>
</Control>
4.点击发送消息,右边对话框即可显示消息交互的过程。(图就不截了~)

二.业务时序图:



三.消息详解:

第一步,UAS-->UAC
设备控制命令同样是采用Message消息
Content-type头域为Application/MANSCDP+xml,设备状态查询命令采用MANSCDP协议格式,具体参见GBT28181国标。
请求命令包含命令类型(CmdType)、命令序列号(SN)、设备编码(DeviceID)
MESSAGE sip:34020000001320000001@3402000000 SIP/2.0

</Control>

第二步,UAC-->UAS
UAC收到请求后,立马返回200 0K响应

SIP/2.0 200 OK
Via: SIP/2.0/UDP 192.168.10.177:5060;branch=z9hG4bKc2be9be1-4121-42af-b4e2-e4896ab42120_53173353_18042259617961

CSeq: 1 MESSAGE
User-Agent: eXosip/3.6.0
Content-Length: 0

第三步,UAC-->UAS
源设备响应服务器的设备远程启动请求,同样采用MANSCDP协议,返回状态相关信息
MESSAGE sip:34020000001320000001@192.168.10.177 SIP/2.0
Via: SIP/2.0/UDP 192.168.10.177:5061;rport=5061;branch=z9hG4bK3569164341;received=192.168.10.177

Call-ID: 2825372510
CSeq: 20 MESSAGE
Content-Type: Application/MANSCDP+xml
Max-Forwards: 70
User-Agent: eXosip/3.6.0
Content-Length: 162

<?xml version="1.0"?>
<Response>
<CmdType>DeviceControl</CmdType>
<SN>17298</SN>
<DeviceID>34020000001320000001</DeviceID>
<Result>OK</Result>
</Response>

第四步,UAS-->UAC
服务器收到响应后,立马返回200 OK响应,整个业务结束。

SIP/2.0 200 OK
