SMGP程序 与电信网关连接 是不是的会出现连接断开，因为我们有个重连机制，可能需要过10分钟，或者时间更长1天或者更长时间才能连接上网关，请高手赐教！！！
但是SMGP程序是采用长连接的，如果信道上（连接）没有数据，获发送链路包（心跳包）来维持连接，
我自己下了个模拟器测试一直都不会出现这种问题，但是在真是环境下电信网关那 就会出现这种问题，但是网关能支持几百个客户端的连接，网速缓慢因素也不可能（我们传输的数据并不是很大，对于电信网关来说足以）
我自己现在采用了两种模式：多进程时候 我开启多个SMGP程序去连接电信网关 这时只开启一对收发线程 也没问题的，（我自己在模拟环境下测试OK的。）
当采用多线程连接时候 采用并发 也没问题， 我这个程序有个隔3秒就重连，但是程序一直重连失败 不知道啥问题，想请教各位？ 我自己认为是网关关闭了连接，但是我每次在调用socket后都会关闭的啊 郁闷死了，！！！而且每次recv时候我都会设置超时操作！！

------解决方案--------------------
sleep（3）不是三秒，而且，smgp是采用的socket通信，不想cmpp协议采用的心跳来维持长连接，smgp是短连接，所有你建的重练机制完全可以在socket连接失败出现异常时在连接，不需要sleep来做，还有最好在两个socket直接使用单线程！
