基于虚拟链接的移动终端多通道融合通信方法

Multi-channels Converged Communication Method in Mobile Terminals Based on Virtual Link

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 region overlapping multiple radio signals such as 3G/4G and Wi-Fi, the mobile terminal usually only chooses one of sigals to transmit data. It limits the access bandwidth of the mobile terminal, influences the upper applications running on the devices, and increases the costs of data communication. A new multi-channels converged communication method was proposed according to the analysis of existing technology. The method used the virtual link receiving all the packets sent by upper applications, and sent the packets simultaneously in multi-channels according to the status of every physical channel. The specific implementation processes were given about the system of multi-channels converged communication, and the system was tested and analyzed. The result of test shows that the method is able to start simultaneously using the physical channels such as 3G/4G and Wi-Fi. The average access bandwith of the mobile terminal is improved significantly.
