METHOD OF TRANSMITTING SMALL AMOUNT OF UPLINK DATA AND METHOD OF RECEIVING SMALL AMOUNT OF UPLINK DATA
First Claim
1. A method of transmitting uplink data at a terminal, comprising:
- detecting uplink data to be transmitted;
determining whether or not uplink data transmission is necessary only once;
transmitting a service request message including information instructing that a data radio bearer not be generated when it is determined that uplink data transmission is necessary only once;
starting a radio resource control (RRC) connection setup process; and
performing the uplink data transmission once using a signaling radio bearer without generating the data radio bearer with reference to the information instructing that the data radio bearer not be generated, during the RRC connection setup process, when it is determined that uplink data transmission is necessary only once.

Abstract
Disclosed is a method of transmitting and receiving a small amount of uplink data. A method of transmitting uplink data includes detecting uplink data to be transmitted, determining whether or not uplink data transmission is necessary only once, transmitting a service request message including information instructing that a data radio bearer not be generated when it is determined that uplink data transmission is necessary only once, starting a radio resource control (RRC) connection setup process, and performing the uplink data transmission once using a signaling radio bearer without generating the data radio bearer with reference to the information instructing that the data radio bearer not be generated, during the RRC connection setup process, when it is determined that \ uplink data transmission is necessary only once.

6. A method of receiving uplink data at a base station, comprising:
-
receiving a radio resource control (RRC) connection request message from a terminal; determining whether or not the RRC connection request message includes information instructing that a data radio bearer not be generated; transmitting an initial UE message including information informing that a data radio bearer is not to be generated to a packet core network when it is determined that the RRC connection request message includes the information instructing that the data radio bearer not be generated; and receiving data from a terminal using a signaling radio bearer without generating the data radio bearer with reference to the information instructing that the data radio bearer not be generated, during an RRC connection setup process performed by the RRC connection request message, when it is determined that the RRC connection request message includes the information instructing that the data radio bearer not be generated. - View Dependent Claims (7)

8. A method of receiving uplink data at a packet core network component, comprising:
-
receiving an initial UE message from a base station (eNB); receiving data from the base station through an enhanced mobility management (EMM) application data message without transmitting a message instructing the base station to generate a data radio bearer when the initial UE message includes information instructing that the data radio bearer not be generated; and transmitting a UE context release request message to the base station. - View Dependent Claims (9)
