移动终端在3G/4G,Wi-Fi等多个无线信号重叠的区域,通常只会选择其中的一种信号进行数据通信,限制了终端网络接入的带宽,影响了上层应用的实现,增加了数据通信的成本。在分析现有的多信道混合通信技术的基础上,提出了一种新的多通道融合通信方法。使用虚拟链接接收上层应用程序发送的所有数据包,根据各个物理信道的状况,将数据包分流到多个物理通道上同时发送出去。给出了该多通道融合通信系统的具体实现过程,对系统进行了测试与分析。测试结果表明:该方法可以同时启用3G/4G,Wi-Fi等物理通道,大幅提升了移动终端的平均接入带宽。
In the area where multiple wireless signals such as 3G / 4G and Wi-Fi overlap, the mobile terminal usually selects only one of the signals for data communication, limits the bandwidth for the terminal network access, affects the implementation of the upper layer application, and adds The cost of data communication. Based on the analysis of the existing multi-channel hybrid communication technology, a new multi-channel fusion communication method is proposed. Use the virtual link to receive all the data packets sent by the upper application, according to the status of each physical channel, the data packet is split to multiple physical channels at the same time send out. The concrete realization process of the multi-channel fusion communication system is given, and the system is tested and analyzed. The test results show that this method can simultaneously enable 3G / 4G, Wi-Fi and other physical channels, greatly improving the average access bandwidth of mobile terminals.
