- Provided are a data transmission method for a detached machine type communication (MTC) device and a mobile communication system providing an MTC service. The method includes sensing an MTC device performing a detachment procedure from a network, when the MTC device being detached is sensed, storing, at a first gateway (GW), context information about the MTC device being detached from the network, storing, at the detached MTC device, context information that has been lastly allocated and used before the detachment, receiving, at the first GW, downlink data transmitted from an MTC server to the detached MTC device, and buffering the received data, transmitting a paging message to the detached MTC device, and performing, at the MTC device receiving the paging message, an attachment process to the network, and receiving the DL data buffered in the first GW.
