Abstract:
Embodiments of the present disclosure provide a communication method, a network side device, and a user terminal. The method includes: establishing, by a user terminal, a connection to a first base station by using a first component carrier; sending, by the first base station, a preprocessing indication message to the user terminal, to indicate that the user terminal is to perform uplink synchronization with a second base station on a second component carrier; and obtaining, by the first base station, a target second base station, and sending a first indication message to the target second base station, to indicate that the user terminal is to perform data transmission with the target second base station.

Claim (Index 19):
The user terminal according to  claim 15 , wherein the processor further executes the instructions to cause the second user terminal to perform the following steps:\n produce a fifth intermediate key of the user terminal in the second base station based on a fourth intermediate key in the first base station and a third counter value pre-configured by the first base station for the user terminal, and producing a third final key of the user terminal in the second base station based on the fifth intermediate key, wherein the third final key is used to encrypt data transmitted by the user terminal to the second base station; receive a first-base-station key update command sent by the second base station, wherein the first-base-station key update command comprises the fifth intermediate key and the third counter value; and produce a sixth intermediate key in the first base station based on the fifth intermediate key and the third counter value, and producing a fourth final key between the second base station and the user terminal based on the sixth intermediate key, wherein the fourth final key is used to encrypt data transmitted by the user terminal to the second base station.
