A method for transmitting and receiving data in a wireless communication system supporting low latency service, the method performed by a terminal comprising: transmitting a request message for switching from an idle state to a connected state to a base station , wherein the idle state is divided into a first mode incapable of data transmission and reception and a second mode capable of low latency service data transmission and reception, and when the RRC layer of the terminal has not been logically connected to a Radio Resource Control, RRC, layer of an Evolved Universal Terrestrial Radio Access Network, E-UTRAN, and a Non-Access Stratum, NAS, layer of the terminal has not been logically connected to the NAS layer of a Mobility Management Entity, MME, the terminal is in the idle state, wherein the request message includes a mode transition information element, IE, field requesting transition to the connected state; receiving a response message including resource information related to a transmission and reception of the low latency service data in response to the request message from the base station ; transmitting or receiving a transfer message including the low latency service data to or from the base station based on the response message; switching from the idle state to the connected state; and transmitting or receiving additional data related to the low latency service data to or from the base station in the connected state, wherein the low latency service data is transmitted or received to or from the base station in the second mode of the idle state, and wherein the additional data related to the low latency service data is transmitted or received to or from the base station in the connected state. transmitting a request message for switching from an idle state to a connected state to a base station , wherein the idle state is divided into a first mode incapable of data transmission and reception and a second mode capable of low latency service data transmission and reception, and when the RRC layer of the terminal has not been logically connected to a Radio Resource Control, RRC, layer of an Evolved Universal Terrestrial Radio Access Network, E-UTRAN, and a Non-Access Stratum, NAS, layer of the terminal has not been logically connected to the NAS layer of a Mobility Management Entity, MME, the terminal is in the idle state, wherein the request message includes a mode transition information element, IE, field requesting transition to the connected state; receiving a response message including resource information related to a transmission and reception of the low latency service data in response to the request message from the base station ; transmitting or receiving a transfer message including the low latency service data to or from the base station based on the response message; switching from the idle state to the connected state; and transmitting or receiving additional data related to the low latency service data to or from the base station in the connected state, wherein the low latency service data is transmitted or received to or from the base station in the second mode of the idle state, and wherein the additional data related to the low latency service data is transmitted or received to or from the base station in the connected state. <EOS>
