[0083] First Embodiment: Controlling Activation After Bearers Using WLAN Radio Resources Are Configured as Inactive method

[0084] As described above, after sending the WLAN measurement report to the eNB, the UE may receive configuration information for applying a new radio configuration from the eNB.

[0085] For example, the UE receives the RRCConenctionReconfiguration message from the eNB, and can apply new radio configuration information included in the corresponding message to the UE.

[0086] For example, the UE may configure a tunnel entity that uses tunnels to control data transmission / reception to be in a disabled (suspended or disabled) state until data transmission can be performed through WLAN radio resources based on WLAN access authentication and tunnel establishment. That is, the UE can configure the tunneling entity to be disabled until figure 1 Operation S180 or S185 or S190 in . Alternatively, the UE may configure the tunnel entity to be in an invalid ...

[0093] The second implementation mode: the method of configuring the bearer of the tunnel after the tunnel is established

[0094] As shown above, after sending the WLAN measurement report to the eNB, the UE may receive configuration information from the eNB for adopting a new radio configuration. For example, the UE receives the RRCConenctionReconfiguration message from the eNB, and applies new radio resource configuration information included in the corresponding message to the UE.

[0095] The new radio resource configuration information for using WLAN radio resources may include WLAN cell configuration information. The WLAN cell configuration information may include at least one or more of the following: WLAN cell identifier information, WLAN mobility set information, WLAN band / frequency information, and WLAN identification information (BSSID / HESSID / SSID). Alternatively, in combination with a cell for which WLAN access authentication is to be performed among WLAN cells,...

[0103] Embodiment 3: A method for simultaneously establishing a tunnel bearer and its associated E-UTRAN bearer

[0104] As described above, after sending the WLAN measurement report to the eNB, the UE may receive configuration information for applying a new radio configuration from the eNB. For example, the UE receives the RRCConenctionReconfiguration message from the eNB, and can apply new radio resource configuration information included in the corresponding message to the UE.

[0105] The new radio resource configuration information for using WLAN radio resources may include WLAN cell configuration information and tunnel bearer configuration information. In addition, the radio resource configuration information may include E-UTRAN bearer configuration information of the E-UTRAN associated with the tunnel bearer. WLAN cells have smaller coverage than E-UTRAN cells and it is difficult to control radio resources. Therefore, the eNB includes the E-UTRAN bearer configuratio...

Abstract

One embodiment of the present invention relates to a method and an apparatus for processing a control plane transmitting and / or receiving predetermined user plain data between a base station and a terminal through a wireless local area network (WLAN) carrier when adding an evolved UMTS terrestrial radio access network (E-UTRAN) carrier to radio resources of a WLAN in a radio access network (RAN) level to transmit the user plane data. In particular, a data transmitting / receiving method of a terminal comprises the following steps of: receiving, from a base station, WLAN cell configuration information using the radio resources of the WLAN to transmit / receive data; performing a WLAN access operation based on the WLAN cell configuration information; transmitting a WLAN access confirmation message to the base station; and receiving tunnel configuration information for enabling the base station and the terminal to set a tunnel through the radio resources of the WLAN from the base station through upper layer signaling.
