摘要
在GPRS数据模式通信中,TCP服务器端意外断开时,GPRS模块仍然保持连接状态造成虚连接现象。提出了缩短未确认时间和定时判断的方法,较好地解决了虚连接现象,实现了GPRS模块自动联网功能。
In view of problems that virtual connection in the communication of GPRS mode resulted by the phenomenon of GPRS module remains connected when TCP server disconnected unexpectedly, this paper proposed a design scheme of shorten the unconfirmed time and time to determine,which gets a better solution of the virtual connection, and achieves the automatic network connection of GPRS module.
