Disclosed are a sending and acquiring method, system and apparatus for a radio resource control (RRC) reestablishment preparation message, relating to the technical field of communication and used for improving cell reestablishment success rate for terminals. In the present invention, when a relay node (RN) prepares a RRC reestablishment preparation message, besides preparing the RRC reestablishment preparation message for a target cell, the RN also prepares a RRC reestablishment preparation message for a donor evolved Node B (DeNB) belonging to the RN and/or cells of other RNs managed by the DeNB, and sends the prepared RRC reestablishment preparation message to the DeNB over a handover request message. After receiving the handover request message, the DeNB needs to parse the handover preparation information in the handover request message, and store the obtained RRC reestablishment preparation message of the cell managed by the DeNB. Employing the technical scheme can greatly improve the reestablishment suc
