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 14):
The second base station according to  claim 10 , wherein the processor further executes the instructions to cause the second base station to perform the following steps:\n produce a second intermediate key between the second base station and the user terminal based on a first intermediate key of the user terminal in the first base station and a first counter value pre-configured by the first base station for the user terminal, and producing a first final key between the second base station and the user terminal based on the second intermediate key, wherein the first final key is used to encrypt data transmitted by the second base station to the user terminal; receive a key update request message sent by the first base station; produce a third intermediate key by using the first intermediate key of the user terminal in the first base station and a second counter value pre-configured by the second base station for the user terminal; and adding the third intermediate key to a key update response message and sending the key update response message to the first base station, wherein the second counter value is different from the first counter value; and send a first-base-station key update command to the user terminal, wherein the first-base-station key update command carries the second counter value, so that the user terminal produces the third intermediate key in the first base station based on the first intermediate key and the second counter value, and produces a second final key between the user terminal and the first base station based on the third intermediate key, wherein the second final key is used to encrypt data transmitted by the user terminal to the first base station.
