[0111] Optionally, if the target communication module is not determined according to each scoring value, a first prompt message is output through the display module or the mobile terminal, wherein the first prompt message is used to prompt the user to move the terminal device to a location with a better signal.

[0112] Specifically, if there is no score value greater than or equal to the preset score threshold among the score values, it means that the target communication module has not been determined according to the score values. At this time, the first prompt information can be displayed through the display module to remind the user to adjust the position of the terminal device to find a location with a better signal.
