The invention discloses a context acquisition method and context acquisition equipment for user equipment (UE). The method comprises that: if a target base station does not store the context of the UE when receiving a radio resource control (RRC) connection reestablishment request message from the UE, the target base station transmits a radio link failure (RLF) indication message to a source base station, wherein the RLF indication message carries indication information requiring the feeding-back of the context of the UE; and the target base station receives a response message of the RLF indication message from the source base station, wherein the response message carries context, acquired according to the indication information by the source base station, of the UE. By the method and the equipment, the target base station not storing the context of the UE can acquire the context of the UE only by the interaction of the two messages, thereby reducing signaling interaction and further increasing the connection reestablishment success rate of the UE.
