<font color=#000000>中国移动<span lang=EN-US>cmnet</span>拨号成功后，会给手机分配一个<span lang=EN-US>10</span>开头的私网<span lang=EN-US>IP</span>，例如：<span lang=EN-US>10.72.90.251</span>。没有公网<span lang=EN-US>IP</span>而只有私网<span lang=EN-US>IP</span>的话，只能通过网关的<span lang=EN-US>NAT</span>转换。对于一般互联网应用无所谓，用起来就像网吧一样。但这样对于某些应用如语音传输是很影响传输效率的</font>

<font color=#000000 size=3>测试地点：上海嘉定区同济大学嘉定校区</font>
<font color=#000000>测试平台：多普达<span lang=EN-US>577w</span>手机，运行<span lang=EN-US>Windows Mobile 5.0</span>系统</font>
<font color=#000000 size=3>测试内容：拨号速度测试、连接速度测试和数据传输速度测试。</font>
<span lang=EN-US>
<font color=#000000>拨号速度测试主要测试<span lang=EN-US>GPRS</span>的拨号速度。从拨号请求发起开始，到<span lang=EN-US>GPRS</span>拨号成功结束。</font>
<font color=#000000>连接速度主要测试网络的路由，<span lang=EN-US>ping</span>的回应速度。</font>
<font color=#000000 size=3>数据传输速度测试主要针对网络的数据上传和下载进行测试。</font>
<span lang=EN-US>
<font color=#000000>拨号速度测试</font>
<font color=#000000> 拨号测试主要测试<span lang=EN-US>GPRS</span>的拨号速度。从拨号请求发起开始，到<span lang=EN-US>GPRS</span>拨号成功结束。</font>
<span lang=EN-US>
<font color=#000000>本测试主要使用<span lang=EN-US>ConnMgrEstablishConnectionSync</span>函数拨号建立连接。代码如下：</font>
