cmpp3.0短信问题 冰天雪地裸体跪求大侠、大神解答

本人做一个项目，需要用到短信功能，只需要发送短信功能，
根据网上的代码拼凑了一个cmpp接口程序，
通过CMPP3.0短信网关模拟器SIM1.8 和
CMPP3.0Smg.exe 两个模拟网关程序测试都没有问题，但到真正在移动网关上测试的时候，
SP请求连接到ISMG（CMPP_CONNECT）的操作能成功，证明说，已经通过验证，和网关建立连接了，可是发送短信的时候，也不知道什么地方出错，就是无法发送成功，
也没有CMPP_CONNECT_RESP 消息返回。

由于小弟只是临阵磨枪，对 CMPP3.0协议理解不深，甚至是c#端口通信也一一知半解，实在是无法找出错误所在，
现在跪求各位大哥大姐帮帮忙，

这是我在CMPP3.0Smg.exe 程序上 测试时的数据包，也不知道是不是数据包有问题，请大家帮看看，

一个找不出错误的菜鸟，痛苦的寻求帮助，人生最痛苦的事莫过于，有错，却找不到错，甚至不知从合入手。

希望大家多多帮助！
