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

摘要

A method for transreceiving data disclosed in the present invention is a method for a terminal transreceiving between a first base station supporting a first radio access technology (RAT) and a second base station supporting a second RAT in a radio access system supporting Multi-RAT, and comprises the following steps: receiving access information for the second base station from the first base station; accessing the second base station based on access information of the second base station; transmitting to the first base station command information including an address on the second RAT, which is used for accessing the second base station; and transreceiving data having a first flow ID from the first base station through the first RAT, and transreceiving data having a second flow ID from the second base station through the second RAT.

1. A method for a terminal transmitting and receiving data between a first base station supporting a first radio access technology (RAT) and a second base station supporting a second RAT in a radio access system supporting multi-RAT, the method comprising:
receiving, by the terminal, a first message including access information for the second base station from the first base station; accessing, by the terminal, the second base station based on the access information included in the first message; transmitting, by the terminal, a second message informing a result of the accessing the second base station by the terminal, wherein the second message includes address information between the terminal and the second base station; and transmitting and receiving, by the terminal, data having a first flow identifier (ID) with the first base station through the first RAT, and transmitting and receiving, by the terminal, data having a second flow ID with the second base station through the second RAT, wherein the data having the first flow ID and the data having the second flow ID are simultaneously transmitted and received between the terminal and the first/second base station, wherein the data having the second flow ID matches with the address information between the terminal and the second base station, wherein the second base station is a selected access point (AP) among a plurality of access points (APs), and wherein the terminal is a multi-RAT terminal that can simultaneously communicate the data with the first base station and the second bases station.
