Abstract: This application provides a frequency band control method in an abnormal scenario of a dual-card terminal and a terminal device, and relates to the field of communications technologies. In solutions of this application, 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 is in a blacklist 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 is in the blacklist 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. Further, when the frequency band combination of the two cards changes and a changed frequency band combination of the two cards is not in the blacklist, the NR capability of the terminal device may be controlled to be restored. In the solutions of this application, a case in which signal quality deteriorates because the dual-card terminal device works on a problem frequency band combination can be alleviated.

Abstract: Embodiments of this application relate to the field of electronic technologies, and provide a network icon display method and a terminal, so that display of a 5G network icon can be more consistent with an actual network status of a terminal, a quantity of times of switching of a network icon can be reduced, and user experience can be improved. A specific solution is as follows: An NR SCG is added to a terminal after the terminal registers with a first cell for the first cell, where the first cell is a long term evolution LTE cell. The terminal registers with the first cell for the second time, where an interval between a time point of registering with the first cell for the second time and a time point of registering with the first cell for the first time is less than or equal to preset duration T. The terminal displays a 5G network icon. Embodiments of this application are used to display a network icon.

Abstract: Embodiments of this application provide a method for selecting a network, applied to an electronic device, the method including: receiving a redirect message, where the redirect message carries information about a first frequency: selecting, based on a signal parameter of the first frequency and a signal parameter of a prior frequency, a target frequency from the first frequency and the prior frequency; and redirecting to a cell at the target frequency. It can be seen that after receiving the redirect message, the electronic device selects, based on the signal parameter of the frequency carried in the redirect message and the signal parameter of the prior frequency, the target frequency to be redirected to. Compared with a manner of redirecting to a cell at the frequency carried in the redirect message, the method is more conducive to selecting a frequency at which a signal is better, and further redirecting to a network in which a signal is better. Therefore, the electronic device has a better network selection function.
