method of controlling channel shift for wireless communications of hybrid terminal device avoiding local-conflict

摘要

The present invention relates to a technology for controlling a channel shift for channel interference cancellation in a frequency band commonly used by a plurality of wireless communication modules in a hybrid terminal device. More specifically, the present invention relates to a technology for preventing a local channel shift to the same channel and enabling a wireless communication module to quickly complete a channel shift and effectively transmit and receive data, by adjusting the shift target channel of the wireless communication modules when a plurality of wireless communication modules mounted on the hybrid terminal device shifts a channel for channel interference cancellation. A control method includes a step of setting a control channel; a step of performing wireless communication; a step of collecting frequency local usage status; a step of detecting a channel interference event; a step of performing a channel shift; a step of retrying a channel shift; and a step of updating frequency local usage status.
