Abstract

本发明提供了一种数据包传输装置及方法，用以解决NB M2M***在进行上行或下行数据包传输过程中，存在的各个数据包传输时间不均衡的问题。本发明方法包括：第一设备根据数据包的最大传输时间设置定时器；当第一设备向第二设备传输数据包时，第一设备启动定时器；第一设备接收第二设备反馈的数据包接收结果，当数据包接收结果为数据包接收失败消息、且定时器未超时时，第一设备向第二设备重传数据包；或者，第一设备接收第二设备反馈的数据包接收结果，当数据包接收结果为数据包接收成功消息、且定时器未超时时，第一设备关闭定时器；或者，第一设备接收第二设备反馈的数据包接收结果，当数据包接收结果为数据包接收失败消息、且定时器超时时，第一设备放弃向第二设备传输数据包。
