Method and apparatus for transmitting/receiving data in mobile communication system
First Claim
1. A method for transmitting data by a terminal in a wireless communication system, the method comprising:
- transmitting, to a base station, a radio resource control (RRC) connection request message if a terminal is in evolved packet system (EPS) connection management idle (ECM-IDLE) state and uplink data associated with an EPS bearer occurs;
receiving a RRC connection setup message in response to the RRC connection request message; and
transmitting a RRC connection setup complete message comprising a non-access stratum (NAS) message, the NAS message including the uplink data associated with the EPS bearer,wherein integrity protection is applied to the NAS message and the uplink data associated with the EPS bearer is ciphered.

Abstract
The present invention relates to a method and an apparatus for transmitting/receiving data, and a method for a user equipment transmitting data, according to one embodiment of the present invention, comprises: a step of determining conditions for determining whether a condition for transmitting short data is satisfied, when data to be transmitted is generated; and a step of including the data to be transmitted in a radio resource control (RRC) connection setup completion message and transmitting same, when the condition for transmitting the short data is satisfied. According to one embodiment of the present invention, the problem of network overload can be prevented by reducing signaling overhead when processing small packets, which are generated intermittently, in the mobile communication system, and an apparatus and a method for enhancing battery performance in the user equipment can be effectively provided.
