Method, apparatus, and system for processing message

A method of processing a message, comprising:

• receiving, by a relay node (RN), a first message sent from a donor base station (DeNB) according to identity information of a cell, the identity information of the reestablished cell is parsed by the DeNB from a handover request message A sent to the DeNB by a source base station (SeNB) and the identity information of the cell being obtained for reestablishing connection in case of a handoff failure from a source cell controlled by the SeNB to the RN through the DeNB;
• obtaining, from the first message, user equipment (UE) context information of the cell, the UE context information of the cell being parsed by the DeNB from the handover request message A;
• and
• preparing, by the RN, a connection for the UE according to the UE context information,
• wherein before the handover request message A is sent from the source base station, the method further comprises:
• sending, by the DeNB, a second message to the SeNB, wherein the second message is used to notify the SeNB of sending a handover request with regard to a target cell and the cell, respectively,
• wherein the handover request message A comprises the UE context information prepared for the cell and excludes UE context information prepared for a target cell.

An apparatus for processing a message, comprising:

• a first receiving unit, configured to receive a handover request message A from a source base station (SeNB);
• a parsing unit, configured to parse the handover request message A to obtain identity information of a cell and user equipment (UE) context information of the cell, the identity information of the cell being obtained for reestablishing connection in case of a handoff failure from a source cell controlled by the SeNB to a Relay Node (RN);
• a first sending unit, configured to send a first message to the RN according to the identity information of the cell, wherein the first message comprises the UE context information prepared for the cell, so that the RN prepares a connection for the UE according to the UE context information;
• a second sending unit, configured to send a second message to the SeNB before the first receiving unit receives the handover request message A from the SeNB, wherein the second message is used to notify the source base station of sending a handover request with regard to a target cell and the cell respectively, wherein:
• the handover request message A comprises the UE context information prepared for the cell, and excludes UE context information prepared for a target cell.
