Abstract
A frequency band control method in an abnormal scenario of a dual-card terminal and a terminal device. For a dual-card user scenario that supports a 5G SA mode or a 5G NSA mode, it is determined whether a frequency band combination of two cards belongs to a preset frequency band combination and whether signal quality of a primary card and/or signal quality of a secondary card meet/meets a preset threshold. If the frequency band combination of the two cards belongs to the preset frequency band combination and the signal quality of the primary card and/or the signal quality of the secondary card are/is less than the preset threshold, an NR capability of a terminal device is controlled to fall back, for example, an SA capability is disabled, or an NR link in an ENDC link is released, to improve the signal quality of the two cards.
