Method for reconstructing radio resource control connection and small base station cluster controller

The invention provides a method for reconstructing a radio resource control connection and a small base station cluster controller. The method for reconstructing the radio resource control connection is applied to the small base station cluster controller and comprises the following steps: receiving request information of acquiring a client context sent by a target small base station, and forwarding the request information to a device where a source cell is located; receiving response information returned by the device where the source cell is located according to a signaling flow that causes the reconstruction of the radio resource control connection of the client; when the response information is success response information, forwarding the information to the target small base station, so that the target small base station executes the reconstruction of the radio resource control connection; and when the response information is failure response information, sending information of acquiring client context fa
