Disclosed in the present invention are a method, device, terminal device and system for adjusting working state of an aggregated link. The method includes: when it is determined that the modulation mode of a first sub-link of an aggregated link will be switched from a first modulation mode to a second modulation mode, the transmission delay in transmitting data slices on the first sub-link with the second modulation mode is determined; the transmission delay in transmitting data slices on the first sub-link with the second modulation mode is compared with the transmission delays in transmitting data slices on other sub-links of the aggregated link to obtain the difference; if the difference meets a preset condition, information for controlling the working state of the first sub-link is sent to a sending end device, so that the sending end device can control the working state of the first sub-link with the second modulation mode. With the present invention, the effect of the change of the sub-link delay difference upon delay difference sensitive services after the modulation mode is switched can be reduced, so that voice, video and other services can be used normally. |
