Specifically, the following steps can be included:

Bl: The UE currently uses two carrier frequencies for communication, and the UE sends a measurement report to the RNC. (This step is optional)

Step 306: The UE detects the HS-SCCH order signaling on the primary carrier frequency of the target cell, and determines that the target can communicate with the target.

Step 307: The UE feeds back a new link establishment through CQI 31 signaling.

Step 308: The target NODEB will send a Cell Change Complete message to the RNC to indicate a new link setup.

Step 309: The RNC will stop sending data to the unused link and release unused resources. The air interface reconfiguration message provided in this embodiment includes at least a cell indicating the carrier frequency information, so that the UE performs multi-carrier air interface reconfiguration in the DC-HSDPA technology according to the modified air interface reconfiguration message.
