1. A data transmission method of a terminal, the method comprising:
- determining whether small data transfer procedure is triggered;
transmitting, to a base station, a radio resource control (RRC) connection request message including a temporary data radio bearer (DRB) request;
receiving an RRC connection setup message, including a temporary DRB configuration, from the base station; and
transmitting data via the temporary DRB.

Abstract
A method and an apparatus for transmitting a small size data packet efficiently while reducing signaling overhead in a mobile communication system are provided. The method includes determining to apply a low security transfer procedure, transmitting, to a base station, a Radio Resource Control (RRC) connection request message including a temporary Data Radio Bearer (DRB) request to which Access Stratum (AS) security is not applied, receiving an RRC connection setup message, including a temporary DRB configuration, from the base station, and transmitting an Internet Protocol (IP) packet over the temporary DRB.

5. A data transmission method of a terminal, the method comprising:
-
determining whether small data transfer procedure is triggered; transmitting a random access preamble to a base station; receiving a random access response (RAR) message from the base station; and transmitting, in response to the receiving of the RAR message, first data including second data received from upper layer to the base station if the small data transfer procedure is triggered. - View Dependent Claims (6, 7)
