Method and apparatus for transreceiving data in radio access system supporting multi-rat

摘要

The present invention relates to a method for a terminal transreceiving data with a first base station supporting first radio access technology (RAT) and a second bases station supporting second RAT in a radio access system supporting Multi-RAT, and comprises the following steps: performing initial network entry with the first base station; negotiating with the first base station Multi-RAT capability for exchanging information necessary to access the second base station; performing the access process with the second base station; and simultaneously transreceiving data between the first base station and the second base station, which is accessed through the access process, wherein the step of negotiating Multi-RAT capability further comprises a step of transmitting control information that expresses a specific service flow or a QoS type, which prefers communication with the second base station, to the first base station.

1. A method for a terminal to transmit and receive data with a first base station supporting a first radio access technology (RAT) and a second base station supporting a second RAT, different from the first RAT, in a radio access system supporting multi-RAT, the method comprising:
performing an initial network entry process with the first base station; performing a multi-RAT capability negotiation process with the first base station in order to exchange information needed to access the second base station, performing an access process with the second base station, and transmitting and receiving data simultaneously with the first base station and the second base station which has been accessed by the access process, wherein performing the multi-RAT capability negotiation process comprises transmitting control information, to the first base station, indicating a specific service flow or a quality of service (QoS) type favoring communication with the second base station that requires a data rate higher than a threshold value, and wherein the control information is transmitted to the first base station through multiple system request messages.
