Abstract
A method and an apparatus for controlling user equipment (UE) context between a plurality of nodes are provided. The method includes transmitting, to a second node, a first message to request a user equipment (UE) context update, receiving, from the second node, a second message indicative of a completion of the UE context update or a third message indicative of a failure of the UE context update in response to the transmission of the first message, and determining whether to retransmit the first message to the second node based on the reception of the second message or the third message. The procedure of the UE context update may be initiated by the transmission of a message to request an operation of the UE context update to be performed between a UE and a third node from the second node to the third node.
