CMPP提供了基于TCP的长连接接口和短连接接口标准，SGIP提供了基于TCP和HTTP/TCP的短连接接口标准。CMPP中的短信网关为TCP服务器，通过接收SP发起的TCP连接来发送MT/MO/Report/Resp等消息。SGIP中发送MT/MTResp时是短信网关为TCP服务器，发送MO/MOResp/Report/ReportResp时短信网关作为TCP客户端。



长连接接口

通信双方以客户-服务器方式建立TCP连接，用于双方信息的相互提交。当信道上没有数据传输时，通信双方应每隔时间C发送链路检测包以维持此连接，当链路检测包发出超过时间T后未收到响应，应立即再发送链路检测包，再连续发送N-1次后仍未得到响应则断开此连接。



短连接接口

通信双方以客户-服务器方式建立TCP连接，应答与请求在同一个连接中完成。系统采用客户/服务器模式，操作以客户端驱动方式发起连接请求，完成一次操作后关闭此连接。-CMPP provides a TCP-based connection interface long and short connection interface standard, SGIP provides a short connection interface based on standard TCP and HTTP/TCP s. The CMPP SMS Gateway is TCP server, SP initiated by receiving a TCP connection to send MT/MO/Report/Resp other news. When SGIP sent MT/MTResp is SMS gateway TCP server, sending MO/MOResp/Report/ReportResp when SMS Gateway as a TCP client.

 

              Long connection interface

              Communicating parties with client- server mode to establish a TCP connection, for the parties to submit information to each other. When there is no data transmission channel, the two sides should be changed every time a communication link C test kits sent to maintain this connection, when the link test packets sent over time T has not received a response, and then immediately send link test packets, and then It has not yet been sent after continuous N-1 times in
