The method includes receiving, from a base station, a first message including bearer related information; identifying access category information based on quality of service (QoS) class identifier (QCI) information included in the bearer related information; transmitting, to the base station, a second message in response to the first message; and transmitting, to a terminal, data based on the access category information. ## Claims ### Claim 1 A method by a wireless local area network (WLAN) termination (WT) node in a second radio access technology (RAT), the method comprising: receiving, from a base station in a first RAT, a WT addition request message including quality of service (QoS) parameters for at least one bearer; identifying access category information for the at least one bearer, based on the QoS parameters received from the base station; transmitting, to the base station, a WT addition request acknowledge message including an identity of an admitted bearer among the at least one bearer and access category information of the admitted bearer based on the admitted bearer being an uplink bearer, the access category information of the admitted bearer being forwarded from the base station to a terminal; and receiving, from the terminal, data based on the access category information. ### Claim 2 (depends on 1) The method of claim 1, wherein the WT addition request message further includes an identity of the at least one bearer, wherein the QoS parameters include at least one of a QoS class identifier (QCI) value, allocation and retention priority (ARP), or guaranteed bit rate (GBR) QoS information, and wherein the access category information for the at least one bearer is identified based on a QoS priority. ### Claim 3 (depends on 1) The method of claim 1, further comprising: considering, if the QoS parameters include a QCI value indicating a guaranteed bit rate (GBR) bearer and the QoS parameters do not include GBR QoS information, an establishment associated with the GBR bearer as failed. ### Claim 4 (depends on 1) The method of claim 1, wherein the WT addition request acknowledge message includes an identity of a bearer which is not admitted. ### Claim 5 A method by a base station in a first radio access technology (RAT), comprising: transmitting, to a wireless local area network (WLAN) termination (WT) node in a second RAT, a WT addition request message including quality of service (QoS) parameters for at least one bearer; receiving, from the WT node, a WT addition request acknowledge message including an identity of an admitted bearer among the at least one bearer and access category information of the admitted bearer based on the admitted bearer being an uplink bearer; and transmitting the access category information of the admitted bearer to the terminal, wherein the access category information is identified, by the WT node, based on the QoS parameters, and wherein the access category information is used by the WT node to receive data from a terminal. ### Claim 6 (depends on 5) The method of claim 5, wherein the WT addition request message further includes an identity of the at least one bearer, wherein the QoS parameters include at least one of a QoS class identifier (QCI) value, allocation and retention priority (ARP), or guaranteed bit rate (GBR) QoS information, and wherein, if the QoS parameters include a QCI value indicating a GBR bearer and the QoS parameters do not include the GBR QoS information, considering an establishment associated with the GBR bearer as failed. ### Claim 7 (depends on 5) The method of claim 5, wherein the WT addition request acknowledge message includes an identity of a bearer which is not admitted, and wherein the access category information is identified based on a QoS priority. ### Claim 8 A wireless local area network (WLAN) termination (WT) node in a second radio access technology (RAT), comprising: a transceiver; and a controller configured to: receive, from a base station in a first RAT, a WT addition request message including quality of service (QoS) parameters for at least one bearer, identify access category information for the at least one bearer, based on the QoS parameters received from the base station, transmit, to the base station, a WT addition request acknowledge message including an identity of an admitted bearer among the at least one bearer and and access category information of the admitted bearer based on the admitted bearer being an uplink bearer, the access category information of the admitted bearer being forwarded from the base station to a terminal, and receive, from the terminal, data based on the access category information. ### Claim 9 (depends on 8) The WT node of claim 8, wherein the WT addition request message further includes an identity of the at least one bearer, wherein the QoS parameters include at least one of a QoS class identifier (QCI) information, allocation and retention priority (ARP), or guaranteed bit rate (GBR) QoS information, and wherein the access category information is identified based on a QoS priority. ### Claim 10 (depends on 9) The WT node of claim 9, wherein the controller is further configured to consider, if the QoS parameters include a QCI value indicating a GBR bearer and the QoS parameters do not include GBR QoS information, an establishment associated with the GBR bearer as failed. ### Claim 11 (depends on 8) The WT node of claim 8, wherein the WT addition request acknowledge message includes an identity of a bearer which is not admitted. ### Claim 12 A base station in a first radio access technology (RAT), comprising: a transceiver; and a controller configured to: transmit, to a wireless local area network (WLAN) termination (WT) node in a second RAT, a WT addition request message including quality of service (QoS) parameters for at least one bearer, receive, from the WT node, a WT addition request acknowledge message including an identity of an admitted bearer among the at least one bearer and access category information of the admitted bearer based on the admitted bearer being an uplink bearer, and transmit the access category information of the admitted bearer to the terminal, wherein the access category information is identified, by the WT node, based on the QoS parameters, and wherein the access category information is used by the WT node to receive data from a terminal. ### Claim 13 (depends on 12) The base station of claim 12, wherein the WT addition request message further includes an identity of the at least one bearer, wherein the QoS parameters include at least one of a QoS class identifier (QCI) value, allocation and retention priority (ARP), or guaranteed bit rate (GBR) QoS information, and wherein the access category information is identified based on a QoS priority. ### Claim 14 (depends on 13) The base station of claim 13, wherein, if the QoS parameters include a QCI value indicating a GBR bearer and the QoS parameters do not include GBR QoS information, considering an establishment associated with the GBR bearer as failed. ### Claim 15 (depends on 12) The base station of claim 12, wherein the WT addition request acknowledge message includes an identity of a bearer which is not admitted.
