.Net/C# 实现 中国移动 CMPP v3.0 ISMG SP 收发短信的 SP 客户端 (CMPP SP Client)

                           /*
.Net/C# 实现 中国移动 CMPP v3.0 ISMG <-> SP 收发短信的 SP 客户端 (CMPP SP Client)
本程序严格按
《中国移动通信企业标准》之《中国移动通信互联网短信网关接口协议(China Mobile Point to Point)》(版本号: 3.0.0)
即: CMPP v3.0.0
http://www.spzone.net/protocol/CMPPV3.0.rar
文档,实现了下面消息的定义及其相关协议级交互:

8.4 业务提供商 (SP) 与互联网短信网关 (ISMG) 间的消息定义 8
8.4.1 SP 请求连接到 ISMG(CMPP_CONNECT) 操作 8
8.4.1.1 CMPP_CONNECT 消息定义 (SP -> ISMG) 8
8.4.1.2 CMPP_CONNECT_RESP消息定义 (ISMG -> SP) 9
8.4.2 SP 或 ISMG 请求拆除连接 (CMPP_TERMINATE)操作 9
8.4.2.1 CMPP_TERMINATE 消息定义 (SP -> ISMG 或 ISMG -> SP) 9
8.4.2.2 CMPP_TERMINATE_RESP 消息定义 (SP -> ISMG 或 ISMG -> SP) 10
8.4.3 SP 向 ISMG提交短信 (CMPP_SUBMIT) 操作 10
8.4.3.1 CMPP_SUBMIT 消息定义 (SP -> ISMG) 10
8.4.3.2 CMPP_SUBMIT_RESP 消息定义 (ISMG -> SP) 11
8.4.5 ISMG 向 SP 送交短信 (CMPP_DELIVER) 操作 13
8.4.5.1 CMPP_DELIVER 消息定义 (ISMG -> SP) 13
8.4.5.2 CMPP_DELIVER_RESP 消息定义 (SP -> ISMG) 16
8.4.7 链路检测 (CMPP_ACTIVE_TEST) 操作 17
8.4.7.1 CMPP_ACTIVE_TEST定义 (SP -> ISMG 或 ISMG <- SP) 17
8.4.7.2 CMPP_ACTIVE_TEST_RESP定义 (SP -> ISMG 或 ISMG <- SP) 17

可采用《中国移动通信 CMPP v3.0 短消息网关模拟器 v1.10》进行测试:

本程序以熟悉理解 CMPP 3.0 协议为主要目的,只将 "消息定义" 对象化,其相关协议级交互并未作更深层次的 OO!
也暂无任何错误处理程序!
消息定义的所有字段名称及其数据类型均与上述之 CMPP v3.0.0 文档完全一致!

其间参阅过 shanhe@优快云 or yexiong@cnBlogs 大作(在此鸣谢):
http://blog.youkuaiyun.com/shanhe/archive/2004/07/19/45383.aspx
http://cnblogs.com/yexiong/articles/115330.aspx
但其中有些消息定义字节错位,因此不能正常交互?!且对象化层次较高,不利于理解协议本身!
遂自己动手,丰衣足食,实现部分主要协议(SP 收发短信):
