Abstract
A method, a terminal, and a storage medium is provided. The method includes: sending, on the first uplink carrier, a random access request to a network device when being out of uplink synchronization on a first uplink carrier in a first uplink frequency range, where the first uplink carrier is a carrier that is determined by the network device in the first uplink frequency range in a paired combination of frequency bands; obtaining, when the random access request on the first uplink carrier fails, a first quantity of failures of the random access request; and determining a first target uplink frequency range in a second uplink frequency range in the paired combination of the frequency bands when the first quantity of failures reaches a preset threshold value, and sending, on a second uplink carrier in the first target uplink frequency range, the random access request to the network device.
