Embodiments of the present invention disclose a parameter configuration method and a configuration device for a mobile terminal. A parameter configuration method for a mobile terminal includes: obtaining a current channel change rate; comparing the current channel change rate with a maximum channel change rate and a minimum channel change rate in each scenario respectively; determining a channel change rate range to which the current channel change rate belongs, and setting a scenario corresponding to the channel change rate range as a target scenario; and obtaining a parameter configuration value group corresponding to the channel change rate range in the target scenario according to a corresponding relationship between a preset parameter configuration value group and the channel change rate range, and configuring a corresponding parameter of each module of the mobile terminal by using each parameter configuration value of the parameter configuration value group.
