Abstract: 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.
