The present invention may provide a method and apparatus for receiving a first message requesting a first service quality from a device, selecting a first session for transmitting the first message according to a specific reference among at least one preconfigured session, transmitting a configuration change request message that requests a configuration change of the first session based on the first service quality to a network node, receiving a configuration change response message indicating a configuration change result in response to the configuration change request message, and transmitting the first message through the first session and the second session according to the configuration change response message. ## Claims ### Claim 1 A method for transmitting and receiving data performed by an eNB in a wireless communication system, comprising: receiving a first message requesting a first service quality from a device, wherein the message includes a first indicator indicating a transmission through a configuration change of a preconfigured session; selecting a first session for transmitting the first message according to a specific criteria among at least one preconfigured session, wherein the first session is a session configured for transmitting at least one message requesting a second service quality; transmitting a configuration change request message that requests a configuration change of the first session based on the first service quality to a network node; receiving a configuration change response message indicating a configuration change result in response to the configuration change request message; and transmitting the first message through the first session or the second session according to the configuration change response message, wherein the message includes at least one of a destination address field including destination information of the message or a source address field including transmitter information of the message. ### Claim 2 (depends on 1) The method of claim 1, wherein the message is transmitted through the first session, when the configuration change response message indicates a configuration change success. ### Claim 3 (depends on 1) The method of claim 1, wherein the message is transmitted through the second session, when the configuration change response message indicates a configuration change failure. ### Claim 4 (depends on 3) The method of claim 3, further comprising: transmitting a request message requesting a configuration of the second session to the network node; and receiving a response message in response to the request message. ### Claim 5 (depends on 3) The method of claim 3, further comprising: transmitting a request message requesting a logical wireless path configuration between the ENB and the device based on the first service quality to the device; and receiving a response message in response to the request message. ### Claim 6 (depends on 1) The method of claim 1, further comprising: receiving a second message including a second identifier indicating whether the eNB supports a transmission through a configuration change of a preconfigured session from the eNB. ### Claim 7 (depends on 1) The method of claim 1, wherein the specific criteria is one of a priority or a similarity with the first service quality. ### Claim 8 (depends on 1) The method of claim 1, further comprising: recovering the configuration of the first session, when a transmission of the first message is completed. ### Claim 9 (depends on 1) The method of claim 1, further comprising: configuring a configuration change maintenance time of the first session based on the first service quality with the terminal or the network node. ### Claim 10 (depends on 9) The method of claim 9, further comprising: recovering the configuration of the first session when the configuration change maintenance time expires. ### Claim 11 A device for transmitting and receiving data in a wireless communication system, comprising: a communication unit for transmitting and receiving a radio signal with exterior; and a processor functionally connected to the communication unit, wherein the processor is configured to perform: receiving a first message requesting a first service quality from a device, wherein the message includes a first indicator indicating a transmission through a configuration change of a preconfigured session; selecting a first session for transmitting the first message according to a specific criteria among at least one preconfigured session, wherein the first session is a session configured for transmitting at least one message requesting a second service quality; transmitting a configuration change request message that requests a configuration change of the first session based on the first service quality to a network node; receiving a configuration change response message indicating a configuration change result in response to the configuration change request message; and transmitting the first message through the first session or the second session according to the configuration change response message, wherein the message includes at least one of a destination address field including destination information of the message or a source address field including transmitter information of the message.
