各位大牛们，实现过或者知道怎么做的请帮我回答一下啊，万分感谢！
Bidirection mode: both platform Server and Tracker can act as TCP socket server, both platform Server can initiate a connection to Tracker and Tracker can initiate a connection to platform Server. GPRS module in Tracker can be opened always to assure wireless link available if platform Server want to initiate a connection to Tracker in anytime.

做服务器首先要有一个唯一的iP地址， 手机通过3G上网获取的是动态iP，
动态iP的话理论上也是可以来做服务器的， 不过要做动态域名解析，
像3g卡有些接入点就可以获取到动态IP, 这种方式理论上应该是可以实现，但如果
像wap接入点这种通过运营商网关（10.10.10.172）转接的方式是不可能实现的。
楼上兄弟应该对此很熟悉吧?因为是国外卡，每张卡都有一个独立的静态IP，是不是就可以直接bind、listen?
