Abstract
A method for managing uplink carrier frequencies is provided, which is applicable to the field of communication. The method includes the following steps: A state switching response message sent by a UE is received, where the state switching response message includes a result of state switching performed by on a secondary uplink carrier serving cell; The result of the state switching is notified to a secondary uplink carrier non-serving cell in a secondary carrier active set through an RNC. A device and a system for managing uplink carrier frequencies are further provided. Through the method, device, and system provided in embodiments of the present invention, the uplink carrier frequencies are managed, so as to facilitate transmission of uplink data during multi-cell collaboration.
