我轉載此文，主要做個記錄。
由於項目原因最近還是好久沒更新博客了，一直想把移動位置訂閱這個更新上去避免檢測的時候遇到和我一樣的問題。移動位置訂閱是國標28181-2016版本新出的協議，協議里面對移動位置訂閱的描述不是很清晰，檢測的時候還單純的以為是移動位置查詢，結果檢測的時候傻眼了，一看還有移動位置訂閱 移動位置取消訂閱 移動位置上班的檢測項，瞬間就知道是理解錯了，最后只能趁檢測人員午休的時候現改代碼，下面說一下移動訂閱的簡單流程。
1、訂閱和取消訂閱流程
直接參考28181文檔里面的訂閱流程：
移動位置訂閱的包體信息：
<?xml version="1.0"?>
<Query>
<CmdType>MobilePosition</CmdType>
<SN>51</SN>
<DeviceID>64000000001310000001</DeviceID>
<Interval>6</Interval>
</Query>
移動位置取消訂閱的包體信息：
<?xml version="1.0"?>
<Query>
<CmdType>MobilePosition</CmdType>
<SN>7</SN>
<DeviceID>64000000001310000001</DeviceID>
</Query>
2、移動位置通知流程
移動位置通知消息，包體內容：
<?xml version="1.0" ?>
<Notify>
<DeviceID>64000000001310000001</DeviceID>
<CmdType>MobilePosition</CmdType>
<SN>128</SN>
<Time>2017-05-19T10:27:58</Time>
<Longitude>116.336</Longitude>
<Latitude>39.942</Latitude>
<Speed>0.0</Speed>
<Direction>0.0</Direction>
<Altitude>0.0</Altitude>
</Notify>

移動位置上報的抓包信息（由於檢測的時候設備還沒有設備廠商過了GB28181-2016檢測，還是采用的定制海康的設備，包體內容還有些小bug給公安一所說了，后面有所修改）:
