Claim:
1. A method of supporting signal transmission and reception using two or more radio access technologies (RATs) by a user equipment (UE), the method comprising: receiving, by the UE from a base station of a first communication network supporting a first RAT, a first message for requesting information regarding whether the UE supports simultaneous access to the two or more RATs; transmitting, by the UE to the base station of the first communication network, a second message containing an indicator indicating whether the UE supports the simultaneous access to the two or more RATs in response to the first message, wherein the second message further contains information indicating a preferred evolved packet system (EPS) bearer QoS type which the UE desires to receive from a base station of a second communication network supporting a second RAT; and simultaneously receiving by the UE: traffic corresponding to the preferred EPS bearer QoS type indicated by the second message, from the base station of the second communication network; and traffic corresponding to a EPS bearer QoS type which is different from the preferred EPS bearer QoS type, from the base station of the first communication network.
