Method, device, and system for managing uplink carrier frequencies
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.
1. A method for managing uplink carrier frequencies, comprising:
receiving, by a Radio Network Controller (RNC), through a Node B Application Part (NBAP) message from a base station, a result of state switching performed by a User Equipment (UE) on a secondary uplink carrier serving cell, wherein the result of state switching performed by the UE on the secondary uplink carrier serving cell is contained in a state switching response message, and wherein a decision of the state switching on a secondary uplink carrier serving cell by the UE is made by the base station;
sending, by the RNC, a state notification message, which indicates the result of state switching performed by the UE on the secondary uplink carrier serving cell, to a secondary uplink carrier non-serving cell in a secondary carrier active set.
2. The method for managing uplink carrier frequencies according to claim 1 , wherein the state notification message is an NBAP message or Frame Protocol (FP) frame.
3. The method for managing uplink carrier frequencies according to claim 1 , wherein the state switching response message is sent through a high speed dedicated physical control channel (HS-DPCCH).
4. The method for managing uplink carrier frequencies according to claim 1 , wherein the result of the state switching comprises the secondary uplink carrier serving cell is activated or the secondary uplink carrier serving cell is deactivated.
5. The method for managing uplink carrier frequencies according to claim 1 , further comprising:
stopping, by the secondary uplink carrier non-serving cell in the secondary carrier active set, detecting an uplink dedicated physical control channel (DPCCH).
