| 摘要 |
The invention provides a method of splitting data to a secondary base station in a carrier aggregation based communication System, a method of ending splitting data to a secondary base station in a carrier aggregation based communication System, and a method of processing data, which is buffered in a secondary base station due to release of a small cell, in a carrier aggregation based communication System. In one embodiment of the present invention, a primary base station sends a control signaling to a user equipment, the control signaling indicating that a small cell is added for the user equipment; receives a confirmation message from the user equipment in response to the control signaling; sends a first indication message to the secondary base station, the first indication message indicating that the primary base station added the small cell for the user equipment; and sends a second indication message to a core network, the second indication message indicating the core network to split the data to the secondary base station; or splits the data to the secondary base station. |
