这里使用WinInet API设计实现了基于IP方式的彩信收发模块。该模块具备与彩信中心(MMSC)通过HTTP方式交互的功能,除了使用IP方式提高发送成功率外,还通过异步工作方式实现了彩信并发、收发进度显示以及中途终止发送和接收的扩展功能,并充分考虑了网络较差的情况。结果表明,该设计优于传统的WAP方式的实现方案。同时,该设计也扩展了无线上网卡的功能,增加了其附加值。
Here use WinInet API design and implementation of the IP-based MMS transceiver module. This module has the function of interacting with Multimedia Message Center (MMSC) via HTTP. In addition to using IP to improve the transmission success rate, this module also realizes MMS extension, sending and receiving progress display and expiration of sending and receiving in the middle through asynchronous operation Fully considered the network is poor. The result shows that the design is superior to the traditional WAP scheme. At the same time, the design also expanded the function of the wireless network card, increasing its added value.
